JQuery Autocomplete zurückkehren Interner Serverfehler

Question

Ich versuche, Jquery Autocomplete mit Wordpress, aber ich verstehe nicht, wo mein Fehler 500 in meinem Code:

Ich denke, die meinen Code in php.

$('#search_type_fiche').autocomplete({ 
     source: function(search, response) { 
      $.ajax({ 
       type: 'POST', 
       dataType: 'json', 
       url: MyAjax.ajaxurl, 
       data: 'action='+MyAjax.action+'&search='+search.term, 
       success: function(data) { 
        response($.map(data, function(item) { 
         return { 
          label: item, 
          value: item 
         } 
       })); 
        //$("p#resultat").html(response(data)); 
       }, 
       error : function(XMLHttpRequest, textStatus, errorThrown) { 
        $("div#ajax-response").removeClass().addClass('error').html('error'); 
       } 
      }); 
      console.log(data); 
     } 
    }); 

Rückruf php:

public $search; 

    public function __construct() 
    { 
     global $wpdb; 
     $this->wpdb = $wpdb; 
    } 

public function SearchTypeFiche($search){ 
     $this->search = $search;  

     $datas = $wpdb->get_results(
      $wpdb->prepare(
       "SELECT slug,id FROM {$this->wpdb->prefix}fiches_type WHERE slug LIKE %s", 
       $this->esc_like(stripslashes($this->search)).'%' 
      ) 
     ); 

     $results = array(); 
     foreach($datas as $key){ 
      $arr   = array(); 
      $arr['label'] = addslashes($key->slug); 
      $arr['value'] = $key->id; 
      $results[] = $arr; 
     }; 
     return json_encode($results);  
    } 

    $data_search = $_POST['search']; 
    parent::SearchTypeFiche($data_search);

Ich versuche zu haben, wo ist das Problem? :

public function search_type_fiche() { 

    $search_data = $wpdb->get_results(
     $wpdb->prepare(
      "SELECT id,slug FROM {$wpdb->prefix}fiches_type WHERE slug LIKE %s", 
      '%'.$_REQUEST['term'].'%' 
     ) 
    ); 

    $suggestions=array(); 

    foreach ($search_data as $post):   
    $suggestion = array(); 
    $suggestion['label'] = $post->slug; 
    $suggestion['link'] = $post->id; 
    $suggestions[]= $suggestion; 
    endforeach; 

    echo $_GET["callback"] . "(" . json_encode($suggestions) . ")"; 



     die(); 
    } 


$("#search_type_fiche").autocomplete({ 
     delay: 0, 
     minLength: 3, 
     source: function(req, response){ 
      $.getJSON(MyAjax.ajaxurl+'?callback=?&action='+MyAjax.action, req, response); 

     }, 
       select: function(event, ui) { 
        window.location.href=ui.item.link; 
       }, 
     } 
     ); 

Warum nicht arbeiten?

Wordpress haben diese und funktionieren:
