Getting CKEditor in Wyvern to not use inline styles

Question

I've seen this post: Remove inline styles from WYGWAM - but it's for WYGWAM. Has anyone successfully changed CKEditor's behavior, from Wyvern, to output this:

<img src="blat.gif" height="200" width="200">

Instead of this:

<img src="blat.gif" style="width:200px; height:200px;">

It's not clear which file I should edit.

Answer 1

Hrmm. I wouldn't recommend changing core files.

:p I feel like being awful today. Here's a PHP solution (turn template on PHP output):

<?php
echo preg_replace("/height\=\\"(\d*)\\" width=\"(\d*)\\"/", 'style="height:$1px; width:$2px;"', '{wyvern_image_field}');
?>

This regex will turn

<img src="blat.gif" height="200" width="200">

to

<img src="blat.gif" style="height:200px; width:200px;">

bunch of edits that was some quote nightmare to get right, lol. AND OH, woops, you wanted it to go the other way. Hold on, regex coming up in a few minutes!

Here ya go, buddy!

<?php
echo preg_replace("/style=\\"height:(\d*)px; width:(\d*)px;\\"/", 'height="$1" width="$2"', '{wyvern_image_field}');
?>

This will take this

<img src="blat.gif" style="height:200px; width:200px;">

and produce this!

<img src="blat.gif" height="200" width="200">

Wyvern has a similar config file, you can add this line to it:

config.disallowedContent = 'img{width,height}';
