Organizzare il codice nel file functions.php del tuo tema WordPress?

Piùpersonalizzo su WordPress,più comincio apensare se dovrei organizzare questofile o suddividerlo.

Più specificamente,se ho un sacco difunzionipersonalizzate che si applicano solo all'area di amministrazionee altre che si applicano solo almio sito Webpubblico,c'è qualchemotivoperincluderetutte lefunzioni di amministrazionenelpropriofile o raggrupparleinsieme?
/p>
Suddividendoliin file separati o raggruppandoliinsieme,sipotrebbe velocizzare un sito Web WordPress oppure WordPress/PHP salta automaticamente lefunzioni che hanno unprefisso di codiceis_admin?

Qual èilmodomigliorepergestire unfile difunzioni digrandi dimensioni (ilmio è lungo 1370 righe).

The more customization I make to WordPress the more I start thinking about if I should be organizing this file or splitting it up.

More specifically, if I have a bunch of custom functions which only apply to the admin area and others which just apply to my public website is there any reason to possibly include all admin functions within their own file or group them together?

Would splitting them up into separate files or grouping them together possibly speed up a WordPress website or does WordPress/PHP automatically skip over functions which have an is_admin code prefix?

What's the best way to deal with a large functions file (mine is 1370 lines long).

Comeincluderei filenelmodogiusto:

funzione wpse1403_bootstrap () { //Qui cariciamo dallanostra directoryinclude //Questo considera anchei temipadree figlio locate_template (array ('inc/foo.class.php'),true,true); } add_action ('after_setup_theme','wpse1403_bootstrap');

Lo stessofunziona anche coni plugin.

Come ottenereilpercorso corretto o URi

Dai anche un'occhiata allefunzioni API delfile system come:

home_url()

plugin_dir_url()

plugin_dir_path()

admin_url()

get_template_directory()

get_template_directory_uri()

get_stylesheet_directory()

get_stylesheet_directory_uri()

ecc.

Come ridurreilnumero di include/require

Se devi recuperare tutti i file da una directory vai con

foreach (glob ('path/to/folder/*.php') as $file) include $file;

Tienipresente che questoignoraglierrori (forse utiliper l'usoin produzione)/i filenon caricabili.

Permodificare questo comportamentopotresti voler utilizzare una configurazione diversa durante lo sviluppo:

$files=(defined ('WP_DEBUG') AND WP_DEBUG) ? glob ('percorso/alla/cartella/*.php',GLOB_ERR) :glob ('percorso/a/cartella/*.php') foreach ($file come $file) include $file;

Modifica: approccio OOP/SPL

Dato che sono appenatornatoe ho visto che questa risposta sta ottenendo semprepiù votipositivi,hopensato dipotermostrare come lo stofacendo algiorno d'oggi -in unmondo PHP 5.3+. L'esempio seguente caricatuttii file da una sottocartella ditemi denominata src/. Qui è dove ho lemie librerie chegestiscono determinate attività comemenu,immagini,ecc. Non devinemmenopreoccuparti delnomepoiché ogni singolofile viene caricato. Se hai altre sottocartellein questa directory,vengonoignorate.

\ FilesystemIterator èil supercedor PHP 5.3+ su \ DirectoryIterator . Entrambifannoparte di PHP SPL. Sebbene PHP 5.2 abbia resopossibile disattivare l'estensione SPLincorporata (meno dell'1% ditutte leinstallazioni lo hafatto),SPL orafaparte del core PHP.

& lt;?php Tema dello spazio deinomi; $files=new \ FilesystemIterator (__DIR __. '/src',\ FilesystemIterator :: SKIP_DOTS); foreach ($file come $file) { /** @noinspection PhpIncludeInspection */ ! $files- >isDir ()e includi $files- >getRealPath (); }

Inprecedenza,sebbene supportassi ancora PHP 5.2.x,utilizzavo la seguente soluzione: un \ FilterIterator nella directory src/Filters per recuperare soloi file (enonpuntopuntatori di cartelle)e un \ DirectoryIterator pereseguireil cicloe il caricamento.
tema dello spazio deinomi; usa Theme \ Filters \ IncludeFilter; $files=new IncludeFilter (new \ DirectoryIterator (__DIR __. '/src')); foreach ($file come $file) { include_once $files- > current () - >getRealPath (); }

Il \ FilterIterator è stato così semplice:

& lt;?php spazio deinomi Theme \ Filters; class IncludeFilterestende \ FilterIterator { funzionepubblica accetta () { ritorno ! $this- > current () - >isDot () e $this- > current () - >isFile () e $this- > current () - >isReadable (); } }

Aparteilfatto che PHP 5.2 è ormaimorto/EOL (e anche 5.3),c'èilfatto chenelgioco c'èpiù codicee un altrofile,quindinon c'èmotivo di andare conil successivoe supportare PHP 5.2.x .

Riassunto

Quindi usa Composer e un composer.json pergestire letue dipendenzee lasciarlo automaticamente creailtuo autoloader PHP (cheimporta automaticamente unfile semplicemente chiamando use \ & lt;namespace > \ ClassName ).

Late answer

How to include your files the right way:

function wpse1403_bootstrap() { // Here we load from our includes directory // This considers parent and child themes as well locate_template( array( 'inc/foo.class.php' ), true, true ); } add_action( 'after_setup_theme', 'wpse1403_bootstrap' );

The same works in plugins too.

How to get the right path or URi

Also take a look at file system API functions like:

home_url()

plugin_dir_url()

plugin_dir_path()

admin_url()

get_template_directory()

get_template_directory_uri()

get_stylesheet_directory()

get_stylesheet_directory_uri()

etc.

How to reduce the number of include/require

If you need to fetch all files from a directory go with

foreach ( glob( 'path/to/folder/*.php' ) as $file ) include $file;

Keep in mind that this ignores failures (maybe good for production use)/not loadable files.

To alter this behavior you might want to use a different config during development:

$files = ( defined( 'WP_DEBUG' ) AND WP_DEBUG ) ? glob( 'path/to/folder/*.php', GLOB_ERR ) : glob( 'path/to/folder/*.php' ) foreach ( $files as $file ) include $file;

Edit: OOP/SPL approach

As I just came back and saw that this answer is getting more and more upvotes, I thought I might show how I'm doing it nowadays - in a PHP 5.3+ world. The following example loads all files from a themes subfolder named src/. This is where I have my libraries that handle certain tasks like menus, images, etc. You don't even have to care about the name as every single file gets loaded. If you have other subfolders in this directory, they get ignored.

The \FilesystemIterator is the PHP 5.3+ supercedor over the \DirectoryIterator. Both are part of the PHP SPL. While PHP 5.2 made it possible to turn the built in SPL extension off (below 1% of all installs did that), the SPL now is part of PHP core.

<?php namespace Theme; $files = new \FilesystemIterator( __DIR__.'/src', \FilesystemIterator::SKIP_DOTS ); foreach ( $files as $file ) { /** @noinspection PhpIncludeInspection */ ! $files->isDir() and include $files->getRealPath(); }

Previously while I still supported PHP 5.2.x, I used the following solution: A \FilterIterator in the src/Filters directory to only retrieve files (and not dot pointers of folders) and a \DirectoryIterator to do the looping and loading.
namespace Theme; use Theme\Filters\IncludesFilter; $files = new IncludesFilter( new \DirectoryIterator( __DIR__.'/src' ) ); foreach ( $files as $file ) { include_once $files->current()->getRealPath(); }

The \FilterIterator was as easy as that:

<?php namespace Theme\Filters; class IncludesFilter extends \FilterIterator { public function accept() { return ! $this->current()->isDot() and $this->current()->isFile() and $this->current()->isReadable(); } }

Aside from PHP 5.2 being dead/EOL by now (and 5.3 as well), there's the fact that it's more code and one more file in the game, so there's no reason to go with the later and support PHP 5.2.x.

Summed up

EDIT The obviously correct way is to use namespaced code, prepared for PSR-4 autoloading by putting everything in the appropriate directory that already is defined via the namespace. Then just use Composer and a composer.json to manage your dependencies and let it auto-build your PHP autoloader (that imports automatically a file by just calling use \<namespace>\ClassName). That's the de-facto standard in the PHP world, the easiest way to go and even more pre-automated and simplified by WP Starter.

Mipiace usare unafunzioneperi file all'interno di una cartella. Questo approccio semplifica l'aggiunta dinuovefunzionalità quando si aggiungononuovifile. Ma scrivo semprein classe o con spazi deinomi: dagli unmaggiore controllo sullo spazio deinomi difunzioni,metodoecc.

Di seguito unpiccoloesempio; utilizzabile anche con l'accordo sulla classe * .php

 funzionepubblica __construct () {

    $this- > load_classes ();
}

/**
 * Restituisce anche una serie difunzionalità
 * Esamina la sottocartella deiplugin "/classes"
 *
 * @ dalla 0.1
 * @return void
 */
funzioneprotetta load_classes () {

//caricatuttii file con la classepattern - *.php dalla directory classes
 foreach (glob (dirname (__FILE__). '/classes/class-*.php') as $ class)
        require_once $ class;

}

In Temi uso spesso un altro scenario. Definisco lafunzione delfileexternelin un ID supporto,vedi l'esempio. Ciò è utile se disattiveròfacilmente lafunzionalità delfileesterno. Uso lafunzioneprincipale di WP require_if_theme_supports () e carica solo se l'ID supportoera attivo. Nell'esempio seguente ho definito questo ID supportatonella rigaprima di caricareilfile.

 /**
     * Aggiunta del supportoper Theme Customizer
     *
     * @ dal 09/06/2012
     */
    add_theme_support ('documentation_customizer',array ('all'));
//Includeilpersonalizzatore deltemaper le opzioni delle opzioni deltema,seiltema è supportato
    require_if_theme_supports (
        "documentation_customizer",
 get_template_directory (). "/inc/theme-customize.php"
    );

Puoi vederepiù di questonel repo di questotema .

I like to use a function to the files inside a folder. This approach makes it easy to add new features when adding new files. But I write always in class or with namespaces - give it more control about the Namespace of functions, method etc.

Below a small example; ut also useage with the agreement about the class*.php

public function __construct() {

    $this->load_classes();
}

/**
 * Returns array of features, also
 * Scans the plugins subfolder "/classes"
 *
 * @since   0.1
 * @return  void
 */
protected function load_classes() {

    // load all files with the pattern class-*.php from the directory classes
    foreach( glob( dirname( __FILE__ ) . '/classes/class-*.php' ) as $class )
        require_once $class;

}

In Themes I use often a other scenario. I define the function of the externel file in a support ID, see the example. That is usefull if I will easy deactivate the feture of the externel file. I use the WP core function require_if_theme_supports() and he load only, if the support ID was active. In the follow example I deifned this supported ID in the line before load the file.

    /**
     * Add support for Theme Customizer
     * 
     * @since  09/06/2012
     */
    add_theme_support( 'documentation_customizer', array( 'all' ) );
    // Include the theme customizer for options of theme options, if theme supported
    require_if_theme_supports( 
        'documentation_customizer',
        get_template_directory() . '/inc/theme-customize.php'
    );

You can see more of this in the repo of this theme.

in termini di scomposizione,nellamiapiastra della caldaia utilizzo unafunzionepersonalizzataper cercare una cartella chiamatafunctionsnella directory deltema,senon è lì la crea. Quindi crea un array dituttii file .php chetrovain quella cartella (sepresenti)edesegue uninclude (); su ciascuno diessi.

In questomodo,ogni volta che devo scrivere qualchenuovafunzionalità,aggiungo semplicemente unfile PHP alla cartella dellefunzionie non devopreoccuparmi di codificarlonel sito.

 <?php

      $files[] = $filename;
    }
    if ($sorting_order == 0) {
      sort($files);
    } else {
      rsort($files);
    }
    return ($files);
  }
}

function get_function_directory_extension($template_url = FALSE) {
  //get template url if not passed

  //replace slashes with dashes for explode
  $template_url_no_slash = str_replace('/', '.', $template_url);

  $template_url_array = array_splice($template_url_array, $offset, 3);
  //put back togther as string
  $template_url_return_string = implode('/', $template_url_array);
  fb::log($template_url_return_string, 'Template'); //firephp

  //if admin, change out of admin folder before storing working dir, then change back again.
  if (is_admin()) {
    $admin_directory = getcwd();
    chdir("..");
    $current_working_directory = getcwd();
    chdir($admin_directory);
  } else {
    $current_working_directory = getcwd();
  }
  fb::log($current_working_directory, 'Directory'); //firephp

  //alternate method is chdir method doesn't work on your server (some windows servers might not like it)
  //if (is_admin()) $current_working_directory = str_replace('/wp-admin','',$current_working_directory);

  $function_folder = $current_working_directory . '/' . $template_url_return_string . '/functions';


  if (!is_dir($function_folder)) mkdir($function_folder); //make folder, if it doesn't already exist (lazy, but useful....ish)
  //return path
  return $function_folder;

}

//removed array elements that do not have extension .php
function only_php_files($scan_dir_list = false) {
  if (!$scan_dir_list || !is_array($scan_dir_list)) return false; //if element not given, or not array, return out of function.
  foreach ($scan_dir_list as $key => $value) {
    if (!strpos($value, '.php')) {

      unset($scan_dir_list[$key]);
    }
  }
  return $scan_dir_list;
}
//runs the functions to create function folder, select it,
//scan it, filter only PHP docs then include them in functions

  if (is_array($all_php_docs)) {
    foreach ($all_php_docs as $include) {
      include($functions_dir . '/' . $include);
    }
  }

}

in terms of breaking it up, in my boiler plate I use a custom function to look for a folder called functions in the theme directory, if it is not there it creates it. Then is creates an array of all the .php files it finds in that folder (if any) and runs an include(); on each of them.

That way, each time I need to write some new functionality, I just add a PHP file to the functions folder, and don't have to worry about coding it into the site.

<?php
/*

//if running on php4, make a scandir functions

      $files[] = $filename;
    }
    if ($sorting_order == 0) {
      sort($files);
    } else {
      rsort($files);
    }
    return ($files);
  }
}
/*

  $template_url_no_slash = str_replace('/', '.', $template_url);

  //create array from URL
  $template_url_array = explode('.', $template_url_no_slash);

  //--splice array

  //Calculate offset(we only need the last three levels)
  //We need to do this to get the proper directory, not the one passed by the server, as scandir doesn't work when aliases get involved.

Bellomaporta a rigidità,anche cosa succede se un attaccante riesce ainserireilproprio codice lì dentro?E se l'ordine degliinclude èimportante?

Nice but it leads to inflexibilities, also what happens if an attacker manages to drop their code in there? And what if the ordering of includes is important?

@kaiser, I suppose you could do it with cron scripts running a function that run's the above folder search but writes the results to a DB/textfile, then bases the loads on that function. This could potentially lead to unfinished work going into the load also.

based on the solution outlined by @mildfuzz - what do you guys believe to be the best method to automatically exclude any file or folder (and its subfiles/folders) from being included within his auto-include approach?

devi solo cambiare `if (! strpos ($ value,'.php'))`perincludere qualunque sistematu scelga.

you just need to change `if (!strpos($value, '.php'))` to include whatever system you choose.

Gestisco un sito con circa 50tipi dipaginapersonalizzati univociin lingue diverse server su un'installazione di rete. Insieme atantissimiplugin.

A un certopunto siamo stati costretti a divideretutto. Unfile difunzioni con 20-30k righe di codicenon è affatto divertente.

Abbiamo deciso di completareil refactoring dituttoil codicepergestiremeglio labase di codice. La struttura deltemapredefinita di wordpress èbuonaperi sitipiccoli,manonperi sitipiùgrandi.

Ilnostronuovofunctions.php contiene solo ciò che ènecessarioper avviareil sito,manulla che appartiene a unapagina specifica.

Il layout deltema che utilizziamo ora è simile almodello diprogettazione MCV,main uno stile di codificaprocedurale.

Adesempio lanostra paginamembri:

page-member.php . Responsabile dell'inizializzazione dellapagina. Chiamare lefunzioni ajax corrette o simili. Potrebbeessereequivalente allaparte Controllernello stile MCV.

functions-member.php . Contienetutte lefunzioni relative a questapagina. Questo è ancheinclusoin altrepagine che richiedonofunzioniperi nostrimembri.

content-member.php . Preparai datiper HTML Potrebbeessereequivalente almodelloin MCV.

layout-member.php . Laparte HTML.

Dopo aver apportato questemodifiche,iltempo di sviluppo èfacilmente diminuito del 50%e orailproprietario delprodotto ha difficoltà afornircinuove attività. :)

I manage a site with about 50 unique custom page types in serveral different languages over a network installation. Along with a TON of plugins.

We where forced to split it all up at some point. A functions file with 20-30k lines of code is not funny at all.

We decided to completley refactor all code in order to manage the codebase better. The default wordpress theme structure is good for small sites, but not for bigger sites.

Our new functions.php only contains what is necessary to start the site, but nothing which belongs to a specific page.

The theme layout we use now is similar to the MCV design pattern, but in a procedural coding style.

For example our member page:

page-member.php. Responsible for initializing the page. Calling the correct ajax functions or similar. Could be equivialent to the Controller part in the MCV style.

functions-member.php. Contains all functions related to this page. This is also included in serveral other pages which need functions for our members.

content-member.php. Prepares the data for HTML Could be equivialent to the Model in MCV.

layout-member.php. The HTML part.

Efter we did these changes the development time have easily dropped by 50% and now the product owner have trouble giving us new tasks. :)

  To make this more helpful you might consider showing how this MVC pattern really works.

Infunctions.php,unmodopiùeleganteper chiamare unfile richiesto sarebbe:

require_once locate_template ('/inc/functions/shortcodes.php');

In functions.php, a more elegant way to call a required file would be:

require_once locate_template('/inc/functions/shortcodes.php');

Ho combinato @kaiser e @mikeschinkel .

Hotutte lemie personalizzazioniperilmiotemain una cartella /includese all'interno di quella cartella hotutto suddivisoin sottocartelle.

Voglio soloincludere /includes/admine i suoi contenuti secondari quando true === is_admin()

Se una cartella vieneesclusain iterator_check_traversal_callback restituendo false,le sue sottodirectorynon verrannoiterate (opassate a iterator_check_traversal_callback)

 /**
 *  Require all customizations under /includes
 */
$includes_import_root = 
    new \RecursiveDirectoryIterator( __DIR__ . '/includes', \FilesystemIterator::SKIP_DOTS );

function iterator_check_traversal_callback( $current, $key, $iterator ) {
    $file_name = $current->getFilename();

    // Only include *.php files
    if ( ! $current->isDir() ) {
        return preg_match( '/^.+\.php$/i', $file_name );
    }

    // Don't include the /includes/admin folder when on the public site
    return 'admin' === $file_name
        ? is_admin()
        : true;
}

$iterator_filter = new \RecursiveCallbackFilterIterator(
    $includes_import_root, 'iterator_check_traversal_callback'
);

foreach ( new \RecursiveIteratorIterator( $iterator_filter ) as $file ) {
    include $file->getRealPath();
}

I combined @kaiser's and @mikeschinkel's answers.

I have all my customizations to my theme in a /includes folder and within that folder I have everything broken out into sub folders.

I only want /includes/admin and its sub-contents to be included when true === is_admin()

If a folder is excluded in iterator_check_traversal_callback by returning false then its sub-directories will not be iterated (or passed to iterator_check_traversal_callback)

/**
 *  Require all customizations under /includes
 */
$includes_import_root = 
    new \RecursiveDirectoryIterator( __DIR__ . '/includes', \FilesystemIterator::SKIP_DOTS );

function iterator_check_traversal_callback( $current, $key, $iterator ) {
    $file_name = $current->getFilename();

    // Only include *.php files
    if ( ! $current->isDir() ) {
        return preg_match( '/^.+\.php$/i', $file_name );
    }

    // Don't include the /includes/admin folder when on the public site
    return 'admin' === $file_name
        ? is_admin()
        : true;
}

$iterator_filter = new \RecursiveCallbackFilterIterator(
    $includes_import_root, 'iterator_check_traversal_callback'
);

foreach ( new \RecursiveIteratorIterator( $iterator_filter ) as $file ) {
    include $file->getRealPath();
}

Se stai arrivando alpuntoin cuiil codicenel functions.php deltuotema stainiziando a sopraffarti,direi sicuramente che seipronto a considerare di dividerloin piùfile. A questopuntotendo afarlo quasiper secondanatura.

Usa Includifilenel `functions.php` File

deltuotema

Creo una sottodirectory chiamata "includes" sotto lamia directory deltemae seguoilmio codicein fileinclude organizzatiin base a ciò che ha sensoperme in quelmomento (il che significa che sto costantemente refactoringe spostandoil codicein giromanmano che un sito sievolve.) Inoltre raramenteinserisco del codice realein functions.php;tutto vanei fileinclude; solo lamiapreferenza.

Soloper darti unesempio,ecco lamiainstallazione diprova che utilizzopertestare lemie risposte alle domande qui su WordPress Answers. Ogni volta che rispondo a una domandatengoil codicein gironel casone avessibisogno dinuovo. Questonon èesattamente quello chefaraiper un sito live,mamostrai meccanismi della suddivisione del codice:

 <?php 
/*
 * functions.php
 * 
 */
require_once( __DIR__ . '/includes/null-meta-compare.php');
require_once( __DIR__ . '/includes/older-examples.php');
require_once( __DIR__ . '/includes/wp-admin-menu-classes.php');
require_once( __DIR__ . '/includes/admin-menu-function-examples.php');

require_once( __DIR__ . '/includes/301-redirects.php');

Oppure creaplug-in

Trova qualcosa cheti piacee rispettalo,ma lascia che latua strategia sievolvaneltempomanmano cheimpari dipiùe ti sentipiù atuo agio.

If you are getting to the point where the code in your theme's functions.php is starting to overwhelm you I would definitely say you are ready to consider splitting it up into multiple files. I tend to do that almost by second nature at this point.

Use Include Files in your Theme's `functions.php` File

I create a subdirectory called "includes" under my theme directory and segment my code into include files organized by what makes sense to me at the time (which means I'm constantly refactoring and moving code around as a site evolves.) I also rarely put any real code in functions.php; everything goes in the include files; just my preference.

Just to give you an example here's my test install that I use to test my answers to questions here on WordPress Answers. Every time I answer a question I keep the code around in case I need it again. This isn't exactly what you'll do for a live site but it shows the mechanics of splitting up the code:

<?php 
/*
 * functions.php
 * 
 */
require_once( __DIR__ . '/includes/null-meta-compare.php');
require_once( __DIR__ . '/includes/older-examples.php');
require_once( __DIR__ . '/includes/wp-admin-menu-classes.php');
require_once( __DIR__ . '/includes/admin-menu-function-examples.php');

// WA: Adding a Taxonomy Filter to Admin List for a Custom Post Type?
// http://wordpress.stackexchange.com/questions/578/
require_once( __DIR__ . '/includes/cpt-filtering-in-admin.php'); 
require_once( __DIR__ . '/includes/category-fields.php');
require_once( __DIR__ . '/includes/post-list-shortcode.php');
require_once( __DIR__ . '/includes/car-type-urls.php');
require_once( __DIR__ . '/includes/buffer-all.php');
require_once( __DIR__ . '/includes/get-page-selector.php');

// http://wordpress.stackexchange.com/questions/907/
require_once( __DIR__ . '/includes/top-5-posts-per-category.php'); 

// http://wordpress.stackexchange.com/questions/951/
require_once( __DIR__ . '/includes/alternate-category-metabox.php');  

// http://lists.automattic.com/pipermail/wp-hackers/2010-August/034384.html
require_once( __DIR__ . '/includes/remove-status.php');  

// http://wordpress.stackexchange.com/questions/1027/removing-the-your-backup-folder-might-be-visible-to-the-public-message-generate
require_once( __DIR__ . '/includes/301-redirects.php');

Or Create Plugins

Another option it to start grouping your code by function and create your own plugins. For me I start coding in the theme's functions.php file and by the time I get the code fleshed out I've moved most of my code into plugins.

However NO Significant Performance Gain From PHP Code Organization

On the other hand structuring your PHP files is 99% about creating order and maintainability and 1% about performance, if that (organizing .js and .css files called by the browser via HTTP is a completely different case and has huge performance implications.) But how you organize your PHP code on the server pretty much doesn't matter from a performance perspective.

And Code Organization is Personal Preference

And last but not least code organization is personal preference. Some people would hate how I organize code just as I might hate how they do it too. Find something you like and stick with it, but allow your strategy to evolve over time as you learn more and get more comfortable with it.

Bella risposta,sono appena arrivato a questopuntoin cui hobisogno di dividereilfile dellefunzioni.Quandopensi che sia utilepassare dafrunctions.php a unplugin.Nellatua risposta hai detto: _quando ho arricchitoil codice ho spostato lamaggiorparte delmio codicenei plugin_.Non lo capisco completamente,cosaintendi con rimpolpato.

Nice answer, I just arrived to this point where i need to split the functions file. When do you think it's handy to move from frunctions.php to a plugin. You said in your answer: _by the time I get the code fleshed out I've moved most of my code into plugins_. I do not understand that fully, what do you mean with fleshed out.

Attenzione: dovresti usare `__DIR__`invece di` __DIR ___ `,altrimentiti verràpresentato unerroreinterno del server (500).

Caution: you'd need to use `__DIR__` instead of `__DIR___`, otherwise you'll be presented with an Internal Server Error (500).
