Ajax Shortinit: Simple

Benchmark

Accélération de près de  ~80% de la requête Ajax.

Fichier de Gestion Ajax

<?php
// File: ajax.php (Root WP Install)

Action Ajax

<?php
// File: /wp-content/themes/my_theme/includes/ajax-actions.php
add_action('wp_ajax_my_action', 'hwk_ajax_my_action');
function hwk_ajax_my_action(){
global $wpdb;
//$wpdb->get_results("SELECT * FROM …");
}

Javascript

$.ajax({
url: 'ajax.php', // WP root install file: ajax.php
data: {
action: 'my_action',
variable: 'my_variable'
},
type: 'post',
success: function(response){
console.log(response);
}
});
