我的WordPress function.php文件中有图像上传功能，但我的function.php文件是用离子立方体编码器编码的，所以我无法编辑该功能。
但我有一个完整的代码，由我的主题作者给出。并且作者告诉我覆盖它将起作用的功能。
我的函数名称为pinc_upload_pin()，并添加为add_action('wp_ajax_pinc-upload-pin', 'pinc_upload_pin');
现在我需要覆盖上面的功能。
我试过创建一个单独的文件名function_new.php并将其包含在header.php中，就像使用require_once一样。我使用remove_action('wp_ajax_pinc-upload-pin', 'pinc_upload_pin');
并添加我自己的函数并挂钩它。以下是我的function_new.php代码
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);

但我的这个新功能无法调用。它仍然调用旧函数pinc_upload_pin();
请指导我错过的地方
答案 0 :(得分：0)
如何以比旧函数更高的优先级挂钩新函数，然后删除该函数中的前一个钩子，以便只调用新函数。
未经测试但可能通过为您的钩子提供优先级9（任何小于10的数字，因为默认优先级为10，如果未指定）可能会起作用，如下所示：
add_action('wp_ajax_pinc-upload-pin', 'pinc_upload_pin_new',9); // High priority
add_action('wp_ajax_nopriv_pinc-upload-pin', 'pinc_upload_pin_new',9); // Use this line only if you need this hook for non-logged in users as well
function pinc_upload_pin_new(){
remove_action('wp_ajax_pinc-upload-pin', 'pinc_upload_pin');
check_ajax_referer('upload_pin', 'ajax-nonce');
do_action('pinc_before_upload_pin', $_POST);

对于任何人，如果上述答案不适合你，那么这里是一个删除主题添加的动作钩子的替代方法。
function wpso682524_remove_action()
{
//Remove the unwanted previous hook added by your theme.
remove_action('wp_ajax_pinc-upload-pin', 'pinc_upload_pin');
//Now hook your new function to that hook.
add_action('wp_ajax_pinc-upload-pin', 'pinc_upload_pin_new',9);
}
add_action('after_setup_theme', 'wpso682524_remove_action');
