Sto creando un childthemeper laprima voltae avevo alcune domande sul codice aggiunto all'intestazione.

In untemanon child c'è un certo codice che aggiungo almiofile header.php comegoogle analytics,google webmastertools,buy sell ads,Facebook opengraph,ecc ....

Come siesegue questa operazionein un childtheme?Crei unfile header.phpneltuo childtheme?In caso affermativo,come sifa?È lo stesso @import che ho usato sul css?

Grazie.

I'm creating a child theme for the first time and I had a few questions regarding code added to header.

In a non child theme there is certain code I add to my header.php file such as google analytics, google webmaster tools, buy sell ads, Facebook open graph, etc....

How do you do this in a child theme? Do you create a header.php file in your child theme? If so how is this done? Is it the same as the @import as I used on the css?

Thanks.

Permodificare l'intestazionein untemafiglio,copiailfile header.php daltemaprincipaleneltemafiglioe quindimodificalo.WordPress vedrà che hai un header.phpneltuotemafiglioe lo userà alposto deltemaprincipale header.php

Qualsiasifilemodello cheinseriscineltuotemafiglio avrà lapriorità sullo stessofileneltemaprincipale quando viene richiamato da WordPress.

Tutto ciò che vaneltag dovrebbeesserefatto usando qualcosa come lafunzionenella risposta di Brians.Se è specifico deltema,puoiinserirloin unfile chiamatofunctions.phpnella cartella deltema senzapassaggi aggiuntivi.

To modify the header in a child theme, copy the header.php from the parent theme into the child theme and then modify it. WordPress will see that you have a header.php in your child theme and use that instead of the parent theme header.php

Any template files you put in your child theme will take priority over the same file in the parent theme when called by WordPress.

Anything that goes in the tag should be done using something such as the function in Brians answer. If it's theme specific, you can put it in a file called functions.php in your theme folder without any extra steps.
- Tom,grazie.Quindi,se hobisogno diinstallare 5 diversiframmenti di codicenelfile header.php,posso solo creare unplugine installarlo?Avrei ancorabisogno di copiareilfile header.phpnelmio childtheme?
  
  Tom, thanks. So if I need to install 5 different snips of code in the header.php, could I just make one plugin and install that? Would I still need to copy the header.php file into my child theme?

- @RickSmith Se stai astraggendoin unplugin,non c'èmotivo di copiare su header.php.:)
  
  @RickSmith If you are abstracting to a plugin, there's no reason to copy over header.php. :)

- Ilproblema con questa soluzione è che quandoiltema viene aggiornato,perderai le correzioniin header.phpfatte dall'autore.
  
  The problem with this solution is that when the theme is updated, you will miss out on fixes in header.php made by the author.

- WordPress sovrascrive l'interofile o aggiunge solonuovo contenuto alfileprincipale?
  
  does WordPress override the whole file, or is it just appending new content to the parent file?

Grazie a Brian Fegter . Se questa risposta aiuta,valuta la risposta di Brian proprio qui sopra.

Questo è unesempio completamentefunzionale di come aggiungereelementi all '"intestazione"tramiteilproprioplugin. In questo caso,sto aggiungendo leproprietà di Facebook Open Graphperi pulsanti Condividie Mipiace.

Basta creare unfile PHP conilnome specificatoin "Plugin Script" all'inizio del codice diesempio,inserirloin una cartella con lo stessonome senzaestensione,ovviamente,e copiare questa cartellanella destinazione "/wp -content/plugins ".

Quindiin "Wordpress",aggiorna "Plugin"e vedraiiltuonuovoplugininstallato. Basta attivarloe letuepagineinizieranno a contenerei metadati di Open Graph Facebooke Twitter.

inserisci qui la descrizione dell'immagine

MOLTO IMPORTANTE: ilfile PHP deveessere codificatoin UTF-8 senza BOMe non deve contenere assolutamente alcun carattere allafine. Devegarantire questo.

Iltitolo sarà la concatenazione delnome dellapagina corrente eilnome del sito.
Seesiste un campopersonalizzato chiamato "metadescription",ilpluginprova perprendere la descrizione da questo campo. Altrimenti,prendiilfile descrizione dall'estratto.
Come l'immagine,ilplugin cerca di utilizzare laminiatura del contenuto immaginenellapagina.

Thanks to Brian Fegter. If this answer helps, please rate for Brian's answer right here above.

This is a fully functional example of how to add things to the "header" by its own plugin. In this case, I am adding the properties of Facebook Open Graph for the Share and Like buttons.

Just create a PHP file with the name specified in "Plugin Script" at the beginning of the sample code, place it in a folder with the same name without the extension, obviously, and copy this folder to the destination "/ wp-content / plugins".

Then within "Wordpress", refresh "Plugins" and you'll see your new plugin installed. Just Activate it, and your pages will begin to contain the metadata of Open Graph Facebook and Twitter.

enter image description here

VERY IMPORTANT: The PHP file must be encoded in UTF-8 without BOM, and should have absolutely no character at the end. Must ensure this.

Anyone who is interested in the functionality of the plugin.

The title will be the concatenation of the name of the current page and the site name.
If a custom field called "metadescription" exists, the plugin tries to take the description from this field. Otherwise, take the description from the excerpt.
As the image, the plugin tries to use the thumbnail of the featured image on the page.

Perfavore usa `esc_attr ()`peri contenuti dell'attributo HTML.

Please use `esc_attr()` for the HTML attribute contents.

Vorrei collegarmi all'azione wp_head.Lomettereiin unpluginin modo da astrarlo daltuo livello dipresentazione.Ciò consente la scalabilitàe lamodifica deitemi.Ciòpreviene anche qualsiasi danno collaterale all'analisi se viene saltato unpassaggionellamigrazione da untema a quello successivo.

 add_action('wp_head', 'wpse_43672_wp_head');
function wpse_43672_wp_head(){
    //Close PHP tags 
    ?>
    ADD YOUR PLAIN HTML CODE HERE
    <?php //Open PHP tags
}

I would hook into the wp_head action. I would place this in a plugin so as to abstract it from your presentation layer. This allows for scalability and changing of themes. This also prevents any analytics collateral damage if a step is missed in migration from one theme to the next.

add_action('wp_head', 'wpse_43672_wp_head');
function wpse_43672_wp_head(){
    //Close PHP tags 
    ?>
    ADD YOUR PLAIN HTML CODE HERE
    <?php //Open PHP tags
}

Grazie.Non ho alcunaesperienzanella creazione di unplug-in. Ho circa 5pezzi di codice che vorrei aggiungerenell'intestazione.Avreibisogno di collegare ciascuno diessi?

Thanks. I don't have any experience in making a plug in. I have about 5 pieces of code I'd like to add into the header. Would I need to make a plug in for each of them?

Sia che si utilizzi untemapadre,untemafiglio o qualsiasi altrotema,l'approccio * corretto * consistenell'inseriretale codicein una richiamata,agganciato all'action hook appropriato.Potrestimettere questo codicenelfile `functions.php` deltema,o,ancorameglioe come ha suggerito Brian,metterloin [un **plug-in specificoperil sito **] (http://ottopress.com/2011/creazione-di-un-plug-in-snippet-specificoperil sito/).

Whether using a Parent Theme, Child Theme, or any Theme whatsoever, the *correct* approach is to put such code in a callback, hooked into the appropriate action hook. You could put this code in the Theme's `functions.php` file, or, even better and as Brian has suggested, put it in [a **site-specific Plugin**](http://ottopress.com/2011/creating-a-site-specific-snippets-plugin/).

@BrianFegter Thanks so much. Working with Php / child themes is new to me, so I"m learning as I go. Thanks for your patience. :) In my old theme, I went into wordpress admin, than to the editor and added this to the header. Is the better way to add all of that to the plug in?

@BrianFegter Grazie amico!Capito!Hafunzionato.Un'altra domanda veloce.Nelmio vecchiotema avevo unpo 'di scriptjava di compravendita che ho aggiunto alla sezionepiè dipagina deltema (mi è stato detto difarloin modo cheilmiotema venisse caricatoperprimo.) Sarebbegiusto aggiungere quel codice qui,o dovrei aggiungerlo ailpiè dipagina?)

@BrianFegter Thanks man! I got it! That worked. One more quick question. In my old theme I had some buy sell java script that I added to the footer section of theme (I was told to do that so my theme loaded first.) Would it be ok to add that code here, or should I add it to the footer? )
