我有一個應該有四個附加圖像的CPT「Annonce」。現在我構建了一個前端表單,允許用戶提交包含四個圖像上傳字段的帖子。當我嘗試使用多張圖片提交表格時,只有最後一張圖片顯示爲儀表板中的特色。我在「媒體」部分看到了其他圖像,但看不到後期編輯頁面,因此我可以更改或刪除主題。從wordpress前端多圖像上傳

我使用這個代碼在頁面post.php中:

 if ($_FILES) { 
     $files = $_FILES['upload_attachment']; 
     foreach ($files['name'] as $key => $value) { 
      if ($files['name'][$key]) { 
       $file = array(
        'name'  => $files['name'][$key], 
        'type'  => $files['type'][$key], 
        'tmp_name' => $files['tmp_name'][$key], 
        'error' => $files['error'][$key], 
        'size'  => $files['size'][$key] 
       ); 

       $_FILES = array("upload_attachment" => $file); 

       foreach ($_FILES as $file => $array) { 
        $newupload = insert_attachment($file,$post_id); 
       } 
      } 
     } 
    } 
... 

<label for="postPhoto1">Photo 1 :</label> 
<input type="file" name="upload_attachment[]" id="postPhoto1"> 

<label for="postPhoto1">Photo 2 :</label> 
<input type="file" name="upload_attachment[]" id="postPhoto2"> 

和functions.php中我有這樣的功能:

function insert_attachment($file_handler,$post_id,$setthumb='false') { 

    // check to make sure its a successful upload 
    if ($_FILES[$file_handler]['error'] !== UPLOAD_ERR_OK) __return_false(); 

    require_once(ABSPATH . "wp-admin" . '/includes/image.php'); 
    require_once(ABSPATH . "wp-admin" . '/includes/file.php'); 
    require_once(ABSPATH . "wp-admin" . '/includes/media.php'); 

    $attach_id = media_handle_upload($file_handler, $post_id); 

    if ($setthumb) update_post_meta($post_id,'_thumbnail_id',$attach_id); 
    return $attach_id; 
} 

使用這種形式的圖片上傳成功,但只有最後一張圖像被設置爲精選圖像,並且我想在帖子編輯頁面中顯示其他圖像。

有幫助嗎?
