Ich habeeine Desktop-App und verwende $ .getJSON ,ummithilfe des Plugins WP REST API Daten vonmeiner WordPress-Site abzurufen. Diesfunktioniertgut undichgehe davon aus,dassich aucheine Funktionin der Dateifunctions.php? Ajax aufrufen kann. Wiemacheich das? Keines der Beispiele,dieichgesehen habe,liefert die AjaxURL. Wiefindeich heraus,was dasist?

Ich habe denfolgenden Code:

Functions.php (in der WordPress-Site auf dem 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 (lokalmit dem Knoten-Webkit vom Computer aus ausführen)

 //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);
});

------------------- BEARBEITEN ----------------------

Nach der Antwort unten habeich denfolgenden Codebasierend auf den Ratschlägen ausprobiert,aberichbekomme

"index.html: 324 Nichterfasster Referenzfehler: ajax_paramsistnicht definiert"

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); });

Wennich die Funktion add_ajax_script () entferne undeinfach diefolgende verwende,wird 0 zurückgegeben.

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

Bitte helfen Sie ...

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...

Und dein 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');

Oben wird Ihre Funktion als Ajax-Aktion hinzugefügt. Anschließend rufen Sie den Funktionsnamenin Ihrem AJAX auf.

Siehe https://codex.wordpress.org/Plugin_API/Action_Reference/wp_ajax_ (Aktion)

//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.

Führen Sie anstelle von "$files zurückgeben" "echo $files" aus.

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

Versuchen Sie: `functionfolder_contents () { Echo 'Hallo'; sterben(); } ` Sehen Sie das Wort Halloin der console.log?

Try: `function folder_contents() { echo 'hello'; die(); }` Do you see the word hello come out in the console.log?

In Ihrem Code sehen Sie,dass Sie das Skript 'ajax-js' lokalisieren,aberbefindet sich das Skript selbstin der Warteschlange?Ichmusste voreinigen Wochen wp_localize-Skripte verwenden undmein JS-Skriptin die Funktion wp_localize scripteinreihen.Zum Beispiel:

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' => '' ) ); }

Ich hoffe,dies hilftbeim Debuggen des Problems.

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.

Das JS wird auf der Site selbstnicht verwendet.Er verwendet den JSin einer Desktop-Anwendung.

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

Der WP-Codex besagt,dass Sie dieglobale Variable ajaxurl verwenden könnenohnees zuerst zu deklarieren.Mit anderen Worten,kommentieren Sie diese Zeile aus:

var ajaxurl = ajax_params.ajax_url;

... und sehen Sie,ob dasfunktioniert.

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);
});

Und dein 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');

Oben wird Ihre Funktion als Ajax-Aktion hinzugefügt. Anschließend rufen Sie den Funktionsnamenin Ihrem AJAX auf.

Siehe https://codex.wordpress.org/Plugin_API/Action_Reference/wp_ajax_ (Aktion)

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');
