Question

我在我的functions.php文件中使用wp_enqueue_script（）为前端用户提供了使用dropzone.js上传图像的功能。它使我的方面非常缓慢，我得到这个错误：

wp_enqueue_script was called incorrectly. Scripts and styles should not be registered or enqueued until the wp_enqueue_scripts, admin_enqueue_scripts, or login_enqueue_scripts hooks.

这是有问题的代码，它工作得很好，完全符合我的要求，但会让我的网站变慢。我在这里做错了什么？

wp_enqueue_script('dropzone','wp-content/themes/storefront/assets/js/dropzone.js', array('jquery'));
wp_enqueue_script('my-script','wp-content/themes/storefront/footer.php', array('jquery','dropzone'));
 $drop_param = array(
  'upload'=>admin_url( 'admin-ajax.php?action=handle_dropped_media' ),
  'delete'=>admin_url( 'admin-ajax.php?action=handle_delete_media' ),
);
wp_localize_script('my-script','dropParam', $drop_param);



add_action( 'wp_ajax_handle_dropped_media', 'BMP_handle_dropped_media' );
add_action( 'wp_ajax_nopriv_handle_dropped_media', 'BMP_handle_dropped_media' );

function BMP_handle_dropped_media() {
   // status_header(200);
    $upload_dir = wp_upload_dir();
    $upload_path = $upload_dir['path'] . DIRECTORY_SEPARATOR;
    $num_files = count($_FILES['file']['tmp_name']);
    $post_id = get_the_ID();

    $newupload = 0;

    if ( !empty($_FILES) ) {
        $files = $_FILES;
        foreach($files as $file) {
            $newfile = array (
                    'name' => $file['name'],
                    'type' => $file['type'],
                    'tmp_name' => $file['tmp_name'],
                    'error' => $file['error'],
                    'size' => $file['size']
            );

            $_FILES = array('upload'=>$newfile);
            foreach($_FILES as $file => $array) {
                $newupload = my_handle_attachment( $file, $post_id );
            }
        }
    }

    echo $newupload;    
    die();
}

add_action( 'wp_ajax_handle_delete_media', 'BMP_handle_delete_media' );
add_action( 'wp_ajax_nopriv_handle_delete_media', 'BMP_handle_delete_media' );
function BMP_handle_delete_media(){

    if( isset($_REQUEST['media_id']) ){

        $post_id = absint( $_REQUEST['media_id'] );

        $status = wp_delete_attachment($post_id, true);

        if( $status )
            echo json_encode(array('status' => 'OK'));
        else
            echo json_encode(array('status' => 'FAILED'));
    }

    die();
}

感谢您的帮助。这是我从原来提取代码的地方。 How to integrate Dropzonejs with wordpress media handler in frontend?

将wp_enqueue_script（）调用包含在函数中：

function your_styles_scripts() { 
    wp_enqueue_script('dropzone','wp-content/themes/storefront/assets/js/dropzone.js', array('jquery'));
    wp_enqueue_script('my-script','wp-content/themes/storefront/footer.php', array('jquery','dropzone'));
    $drop_param = array(
        'upload'=>admin_url( 'admin-ajax.php?action=handle_dropped_media' ),
        'delete'=>admin_url( 'admin-ajax.php?action=handle_delete_media' ),
);
    wp_localize_script('my-script','dropParam', $drop_param);
}

相关的操作挂钩，根据您的用例需要：

add_action( 'admin_enqueue_scripts', 'your_styles_scripts' );

或

add_action( 'wp_enqueue_scripts', 'your_styles_scripts' );
