Admin Ajax gibt 0

Nur als Referenzfür alle,die hierher kommen undgoogeln "Ajax-Anfragegibt 0 zurück": Denken Sie daran,wenn Sie der Methode des Objektseine Ajax-Aktion hinzufügen,um sicherzustellen,dass der Modifikatorfür den Methodenzugriff publicist.

 add_action( 'wp_ajax_my_action', [$object, 'my_method']);
 

add_action wirdnur stummgeschaltet,wenn Ihre Methodenicht außerhalb von $object aufgerufen werden kann.

Just for reference, for anyone who get here googling "ajax request is returning 0": Remember when you add ajax action to object's method to be sure methods access modifier is public.

add_action( 'wp_ajax_my_action', [$object, 'my_method']);

add_action just silences if it can't call your method outside of $object.

Wenn Sie die Funktion wp_localize_script ()nicht zum Festlegen der Ajax-URL verwenden,gibt admin ajax 0 zurück. Ich denke,esistein Wordpress-Fehler.Hieristein Beispiel:

     wp_enqueue_script( 'search_js', get_template_directory_uri() . '/js/search.js', array( 'jquery' ), null, true );    
    wp_localize_script( 'search_js', 'ajaxurl', admin_url( 'admin-ajax.php' ) );
 

Die Javascript-Datei (search.js):

     $('#search_input').autocomplete({
    source: function(request, response) {

        $.ajax({
            type: 'POST',
            dataType: 'json',
            url: ajaxurl,
            data: 'action=my_custom_action_search&search_criteria=' + request.term,
            success: function(data) {
                response(data);
            },
            error: function(errorThrown){
                console.log(errorThrown);
            } 
        });
    },
    minLength: 3
});
 

If you don't use wp_localize_script() function to set ajax url, admin ajax returns 0. I think it's Wordpress bug. Here's is an example :

    wp_enqueue_script( 'search_js', get_template_directory_uri() . '/js/search.js', array( 'jquery' ), null, true );    
    wp_localize_script( 'search_js', 'ajaxurl', admin_url( 'admin-ajax.php' ) );

The javascript file (search.js) :

    $('#search_input').autocomplete({
    source: function(request, response) {

        $.ajax({
            type: 'POST',
            dataType: 'json',
            url: ajaxurl,
            data: 'action=my_custom_action_search&search_criteria=' + request.term,
            success: function(data) {
                response(data);
            },
            error: function(errorThrown){
                console.log(errorThrown);
            } 
        });
    },
    minLength: 3
});

    jQuery('.cl_link_buttons').val('id').click(function() {
       $.ajax({

Diejenigen,die Fehler 0erhalten :),action=> 'action'

 var data = { 'action': 'firmabilgilerikaydet', 'data': form_data };

$.post(ajaxurl, data, function(response) { alert(response); });
 

Those who get error 0 :), action => 'action'

var data = { 'action': 'firmabilgilerikaydet', 'data': form_data };

$.post(ajaxurl, data, function(response) { alert(response); });

Wenn Sie localhost verwenden und sich Ihr PHP-Server-Codein einer Plugin-Dateibefindet,melden Sie sich zuerstbeim Admin-Dashboard an und aktualisieren Sie die Plugin-Seite.Überprüfen Sie zweitens,ob das Plugin aktiviertist.Gehen Sie dann zum Frontend und aktualisieren Siees und versuchen Sieeserneut.

If you are using localhost and your php server side code is in a plugin file first login to admin dashboard and refresh the plugin page. Secondly, check if the plugin is activated. Then go to frontend and refresh and try sending again.

Versuchen Sie,eine if -Anweisung hinzuzufügen:

 function my_function(){
$id = $_POST['variation_id'];

    if(isset($_POST['variation_id'])) { 


//your coded function


die();
}



}// end function
 

Try adding an if statement:

function my_function(){
$id = $_POST['variation_id'];

    if(isset($_POST['variation_id'])) { 


//your coded function


die();
}



}// end function
