我在我的WordPress function.php文件中有圖片上傳功能，但我的function.php文件使用了ioncube編碼器編碼，所以我無法編輯該功能。函數覆蓋問題wordpress
但我有一個由我的主題作者給出的函數的完整代碼。並且作者告訴我重寫它將起作用的那個函數。
我的函數名稱爲pinc_upload_pin()，它被添加像add_action('wp_ajax_pinc-upload-pin', 'pinc_upload_pin');
現在我需要越過上述功能。
我已經嘗試創建一個單獨的文件名稱function_new.php並將其包含在header.php中，就像使用require_once一樣。我已使用remove_action('wp_ajax_pinc-upload-pin', 'pinc_upload_pin');
刪除以上功能，並添加我自己的功能並掛鉤它。下面是我的function_new.php代碼
remove_action('wp_ajax_pinc-upload-pin', 'pinc_upload_pin');
function pinc_upload_pin_new(){
check_ajax_referer('upload_pin', 'ajax-nonce');
do_action('pinc_before_upload_pin', $_POST);
$minWidth = 2;
$minHeight = 2;
$minWidth = apply_filters('pinc_minwidth', $minWidth);
$minHeight = apply_filters('pinc_minheight', $minHeight);
require_once(ABSPATH . 'wp-admin/includes/image.php');
require_once(ABSPATH . 'wp-admin/includes/file.php');
require_once(ABSPATH . 'wp-admin/includes/media.php');

$width = @$imageinfo[0];

但我的這個新功能無法調用。這還叫老功能pinc_upload_pin();
請指導我在那裏失去了一些東西
你確定'pinc_upload_pin'掛鉤已經添加，當你試圖刪除它，所以你的代碼不會運行之前，他們添加該掛鉤？ –
pinc_upload_pin掛鉤在function.php中添加，我正在刪除header.php中的鉤子我正確嗎？ – dhavald99
我的頁腳和函數這兩個文件都被編碼，所以 – dhavald99
