ajax-extend

How to do with ajax-extend?

The javascript code:

$j.ajax( {     url : home_url,     type : 'POST',     dataType : 'html',     data : {         'ajax_extend_mark' : 1, /* this is indispensable if you want ajax-extend to call the function you need. */         'ajax_extend_action' : 'my_function', /* the function name (a WP core function, or a function in one plugin. any functions loaded by wp()) */         'name' : 'sunjianle',     },     success : function(data, textStatus, errorThron) {         alert(data);     } }); 

The background PHP code:

function my_function() {     $name = $_POST["name"];     echo "Hello, " . $name;      global $wpdb;     $query_sql = "select user_login                 from wp_users                 limit 0,10";     $users = $wpdb->get_results($wpdb->prepare($query_sql));     foreach($users as $user){         echo $users->user_login;     } } 

How can I test if ajax-extend is working?

How does ajax-extend work?

add_action( "wp", "ajax_operation" );  function ajax_operation() {     /*      * ajax_extend_mark : 
     * ajax_extend_action :      */     if(isset($_REQUEST["ajax_extend_mark"]))     {         $function_name = $_REQUEST["ajax_extend_action"];         if(!function_exists($function_name))             return;         call_user_func($function_name);         die();     }    
} 

That is the core code and the all code of ajax-extend. What you need to understand the code above.

Are there any limitations to which functions I can use?

Yes. 1. Functions must return valid HTML – this will be called in php and returned via the Ajax call 2. Functions cannot accept any parameters (at least at the moment)
