AJAX調用 - 不承認WordPress的功能/班

Question

我有Ajax調用用於獲得響應，響應文件我已經使用WordPress的循環USNG WP_Query（）類... 但是當我執行Ajax返回致命錯誤： 致命錯誤：類 'WP_Query' 用C未找到：\ XAMPP \ htdocs中\ businessfinder \可溼性粉劑內容\主題\ businessfinder \ metabox \上線Ajax的process.php 20

這裏是AJAX調用代碼：

var path = 'http://localhost/business-finder/wp-content/themes/businessfinder/metabox/ajax-process.php';  
     $.ajax({ 
     type: "POST", 
     url: path, 
     data: { param:folio_data } 
     }).done(function(msg) { 
      $('#ajax_folio').html(msg); 
      //alert("Data Saved: " + msg); 
    }); 

這裏是res龐塞文件代碼：

<?php 


print_r($_POST['param']); 
if(!empty($_POST['param'])): 
      echo spyropress_get_attached_posts1($_POST['param'], 'ait-grid-portfolio'); 
      echo '<br><br>'; 
     endif; 




function spyropress_get_attached_posts1($post_id = '', $post_type = ''){ 
    //if($post_id = '' || $post_type = '') return; 
    $counter = 0; 
    global $wp_query ; 
    $query = new WP_Query(array('post_type' => $post_type, 'post__in' => $post_id)); 
    if($query->have_posts()): 
    $out .= '<table border = "1">'; 
    while($query->have_posts()): 
     $query->the_post(); 
       if($counter == 6): 
      $out .= '<tr class = "post_list">'; 
     else: 
      $counter++; 
     endif;  
      $out .= '<td>'.get_the_post_thumbnail(get_the_ID(), array(100,100)).'<br>'.get_the_title().'</td>'; 

     if($counter == 6): 
     $out .= '</tr>'; 
     $counter = 0; 
     endif;  

    endwhile; 
    $out .= '</table>'; 
    wp_reset_postdata(); 
    else: 
    $out = 'No Posts Found....'; 
    endif; 
wp_reset_query(); 
return $out; 
} 

add_action('init', 'spyropress_get_attached_posts'); 
?>

你寫錯了ajax代碼。你不能像這樣使用ajax。見下面的代碼：

jQuery(document).ready(function($) { 

var dataString = { 
       action: 'my_ajax', 
       param: folio_data 
      }; 
      jQuery.ajax 
      ({ 
       type: "POST", 
       url: "<?php echo admin_url('admin-ajax.php'); ?>", 
       data: dataString, 
       cache: false, 
       success: function(msg) 
       { 
        $('#ajax_folio').html(msg); 
        //alert("Data Saved: " + msg); 

       } 
      }); 
    }); 

function ajaxDataSubmit(){ 
    global $wpdb; 
    $post_id = $_POST['param']; 
    $post_type='ait-grid-portfolio'; 
    $counter = 0; 
    global $wp_query ; 
    $query = new WP_Query(array('post_type' => $post_type, 'post__in' => $post_id)); 
    if($query->have_posts()): 
    $out .= '<table border = "1">'; 
    while($query->have_posts()): 
    $query->the_post(); 
      if($counter == 6): 
     $out .= '<tr class = "post_list">'; 
    else: 
     $counter++; 
    endif;  
     $out .= '<td>'.get_the_post_thumbnail(get_the_ID(), array(100,100)).'<br>'.get_the_title().'</td>'; 

    if($counter == 6): 
    $out .= '</tr>'; 
    $counter = 0; 
    endif;  

endwhile; 
$out .= '</table>'; 
wp_reset_postdata(); 
else: 
    $out = 'No Posts Found....'; 
endif; 
wp_reset_query(); 
die($out); 
}
