回覆社團：https://www.facebook.com/groups/wordpresstw/permalink/1529719560388812/ 「想請教一下大家，有插件可以做到插入相片時，會使用自動設定嗎？ 就是插入後為 width="auto" height="auto" 而不是數字」的問題
<?php
add_action( 'media_send_to_editor', 'mxp_before_insert_media');
function mxp_before_insert_media($html, $id, $attachment) {
//此方法針對全媒體，不只有圖片
$html = preg_replace('/width="(\d+)"/i', 'width="auto"', $html);
$html = preg_replace('/height="(\d+)"/i', 'height="auto"', $html);
