Wordpress更改媒体上传目录

Question

我设法使用以下代码上传我的媒体。不幸的是，媒体在与前端表单发布日期（/ 2014/09 /）相同的月份保存。这是上传用户个人资料图片，而不是附加到任何帖子。希望有人可以帮忙，因为我无法在网上找到任何资源。谢谢！

        // UPLOAD USER IMAGE
            function upload_user_image($user, $nonce_name, $input_name, $field_name ) {
            if ( 
                isset( $_POST[$nonce_name] ) 
                && wp_verify_nonce( $_POST[$nonce_name], $input_name )

            ) {


                $arr_file_type = wp_check_filetype(basename($_FILES[$input_name]['name']));
                $uploaded_file_type = $arr_file_type['type'];
                $allowed_file_types = array('image/jpg','image/jpeg','image/gif','image/png');
                if(in_array($uploaded_file_type, $allowed_file_types)) {


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


                    $attachment_id = media_handle_upload( $input_name, 0 );

                    if ( is_wp_error( $attachment_id ) ) {
                        $upload_feedback = 'There was a problem with your upload.';
                    } else {
                        $upload_feedback = false;
                    }
                    update_user_meta( $user, $field_name, $attachment_id );


                } else {
                    $upload_feedback = 'Please upload only image files (jpg, gif or png).';
                }



            } else {

                $upload_feedback = 'Security check failed';
            }
            }
