Ho un'app desktope utilizzo $ .getJSON per ottenere dati dalmio sito wordpress utilizzandoilplug-in WP REST API . Funzionabene e quindipresumo dipoter ancheeffettuare una chiamata Ajax a unafunzionein functions.php? Comefaccio afare questo? Nessuno degliesempi che ho vistofornisce ajaxURL. Comefaccio a sapere di cosa sitratta?

Hoil seguente codice:

Functions.php (nel sito wordpress sul server)

 //Called by Ajax from App - list the contents of the folder so they can be downloaded and stored locally
function folder_contents() {

    $folderPath = $_POST['path'] ;
    $files = array_diff(scandir($path), array('.', '..'));
    print_r($files);
    return $files;

    die(); 
}

add_action('wp_ajax_my_action', 'folder_contents');

app.js (eseguito utilizzandoilnodo webkit localmente dallamacchina)

 //ajax call 
var data = {
    action: 'path',
    path: datafolder;
};
var ajaxurl = baseurl + '';  //WHAT IS THIS?!?!
jQuery.post(ajaxurl, data, function(response) {
    alert('Got this from the server: ' + response);
    console.log(response);
});

------------------- MODIFICA ----------------------

Dopo la risposta di seguito hoprovatoil codice seguentein base al consiglioma ottengo

"index.html: 324 Uncaught ReferenceError: ajax_paramsnon è definito"

Functions.php

//add code to use ajax function add_ajax_script() { wp_localize_script( 'ajax-js', 'ajax_params', array( 'ajax_url' => admin_url( 'admin-ajax.php' ) ) ); } //Called by Ajax from App - list the contents of the folder so they can be downloaded and stored locally function folder_contents() { $folderPath = $_POST['path'] ; $files = array_diff(scandir($path), array('.', '..')); wp_send_json($files); die(); } add_action('wp_ajax_folder_contents', 'folder_contents'); add_action('wp_ajax_nopriv_folder_contents', 'folder_contents'); add_action( 'wp_enqueue_scripts', 'add_ajax_script' );

<"App.js
//ajax call var data = {action: 'powerpoint_folder_contents',path: datafolder}; var ajaxurl = ajax_params.ajax_url; console.log(ajaxurl); jQuery.post(ajaxurl, data, function(response) { alert('Got this from the server: ' + response); console.log(response); });

Se rimuovo lafunzione add_ajax_script () e utilizzo semplicemente quanto segue,restituisce 0.

var ajaxurl=baseurl + 'wp-admin/admin-ajax.php';

Perfavore aiutatemi ...

I have a desktop app and I use $.getJSON to get data from my wordpress site using the plugin the WP REST API. This works fine and so I assume I can also make an Ajax call to a function in the functions.php? How do I do this? None of the examples I have seen supply the ajaxURL. How do I find out what this is?

I have the following code:

Functions.php (in wordpress site on server)

//Called by Ajax from App - list the contents of the folder so they can be downloaded and stored locally function folder_contents() { $folderPath = $_POST['path'] ; $files = array_diff(scandir($path), array('.', '..')); print_r($files); return $files; die(); } add_action('wp_ajax_my_action', 'folder_contents');

app.js (run using node webkit locally from machine)

//ajax call var data = { action: 'path', path: datafolder; }; var ajaxurl = baseurl + ''; //WHAT IS THIS?!?! jQuery.post(ajaxurl, data, function(response) { alert('Got this from the server: ' + response); console.log(response); });

-------------------EDIT----------------------

After the answer below I have tried the below code based on the advice but I get

"index.html:324 Uncaught ReferenceError: ajax_params is not defined"

Functions.php

//add code to use ajax function add_ajax_script() { wp_localize_script( 'ajax-js', 'ajax_params', array( 'ajax_url' => admin_url( 'admin-ajax.php' ) ) ); } //Called by Ajax from App - list the contents of the folder so they can be downloaded and stored locally function folder_contents() { $folderPath = $_POST['path'] ; $files = array_diff(scandir($path), array('.', '..')); wp_send_json($files); die(); } add_action('wp_ajax_folder_contents', 'folder_contents'); add_action('wp_ajax_nopriv_folder_contents', 'folder_contents'); add_action( 'wp_enqueue_scripts', 'add_ajax_script' );

App.js

//ajax call var data = {action: 'powerpoint_folder_contents',path: datafolder}; var ajaxurl = ajax_params.ajax_url; console.log(ajaxurl); jQuery.post(ajaxurl, data, function(response) { alert('Got this from the server: ' + response); console.log(response); });

If I remove the add_ajax_script() function and simply use the below it returns 0.

var ajaxurl = baseurl + 'wp-admin/admin-ajax.php';

Please help...

Eiltuo PHPin functions.php

//Called by Ajax from App - list the contents of the folder so they can be downloaded and stored locally function folder_contents() { $folderPath = $_POST['path'] ; $files = array_diff(scandir($path), array('.', '..')); print_r($files); return $files; die(); } add_action('wp_ajax_folder_contents', 'folder_contents'); add_action('wp_ajax_nopriv_folder_contents', 'folder_contents');

Quanto sopra aggiunge latuafunzione come azione Ajax. Quindi chiamiilnome dellafunzioneneltuo AJAX.

Vedi https://codex.wordpress.org/Plugin_API/Action_Reference/wp_ajax_ (azione)

//ajax call var data = { action: 'folder_contents', path: datafolder }; var ajaxurl = baseurl + ''; //WHAT IS THIS?!?! jQuery.post(ajaxurl, data, function(response) { alert('Got this from the server: ' + response); console.log(response); });

And your PHP in functions.php

//Called by Ajax from App - list the contents of the folder so they can be downloaded and stored locally function folder_contents() { $folderPath = $_POST['path'] ; $files = array_diff(scandir($path), array('.', '..')); print_r($files); return $files; die(); } add_action('wp_ajax_folder_contents', 'folder_contents'); add_action('wp_ajax_nopriv_folder_contents', 'folder_contents');

The above add your function as an ajax action. You then call the function name in your AJAX.

Invece di "restituisci $file",esegui "echo $file".

Instead of "return $files", do "echo $files".

Neltuo codice vedo che localizzi lo script "ajax-js",ma lo script stesso è accodato?Ho dovuto usaregli script wp_localizepoche settimanefae ho dovuto accodareilmio script JS all'interno dellafunzione che chiamava script wp_localize.Adesempio:

add_action( 'wp_enqueue_scripts', 'google_js_script' ); function google_js_script() { // Enqueue the js script wp_enqueue_script('google-js', GOOGLE_PLG_URL . 'assets/js/google-places.js', array('jquery'), true); // Localize the enqueued JS script wp_localize_script( 'google-js', 'ajax_object', array( 'ajax_url' => admin_url( 'admin-ajax.php' ), 'place' => '' ) ); }

Spero che questo aiuti a risolvereilproblema.

In your code I see you localize the 'ajax-js' script, but is the script itself enqueued? I had to use wp_localize scripts a few weeks ago and I had to enqueue my JS script inside the function that called wp_localize script. For example:

add_action( 'wp_enqueue_scripts', 'google_js_script' ); function google_js_script() { // Enqueue the js script wp_enqueue_script('google-js', GOOGLE_PLG_URL . 'assets/js/google-places.js', array('jquery'), true); // Localize the enqueued JS script wp_localize_script( 'google-js', 'ajax_object', array( 'ajax_url' => admin_url( 'admin-ajax.php' ), 'place' => '' ) ); }

Hope this helps to debug the issue.

Il JSnon viene utilizzato sul sito stesso.Sta usando JS all'interno di un'applicazione desktop.

The JS is not used on the site itself. He is using the JS inside a desktop application.

Il WP Codex afferma chepuoi utilizzare la variabileglobale ajaxurlsenzaprima dichiararlo.In altreparole,commenta questa riga:

var ajaxurl = ajax_params.ajax_url;

...e vedi sefunziona.

The WP Codex states that you can use the global variable ajaxurl without declaring it first. In other words, comment out this line:

var ajaxurl = ajax_params.ajax_url;

...and see if that works.

 //ajax call 
var data = {
    action: 'folder_contents',
    path: datafolder
};
var ajaxurl = baseurl + '';  //WHAT IS THIS?!?!
jQuery.post(ajaxurl, data, function(response) {
    alert('Got this from the server: ' + response);
    console.log(response);
});

Eiltuo PHPin functions.php

 //Called by Ajax from App - list the contents of the folder so they can be downloaded and stored locally
function folder_contents() {

$folderPath = $_POST['path'] ;
$files = array_diff(scandir($path), array('.', '..'));
print_r($files);
return $files;

die(); 
}

add_action('wp_ajax_folder_contents', 'folder_contents');
add_action('wp_ajax_nopriv_folder_contents', 'folder_contents');
