[#37726] - [4.1] Editor custom field 'Safe HTML' setting not working correctly with iframes
- New
- Medium
- Build: 4.1-dev
- # 37726
Steps to reproduce the issue
- Create an article custom field of type Editor
- Select 'Safe HTML' from the Filter options at the bottom of the General tab and save the new field
- If using TinyMCE, ensure 'iframe' is removed from the list of prohibited elements in the plugin settings
or if using JCE Editor ensure that all iframes are allowed in the profiles editor under Plugin parameters > Media support - Open an article that uses that field and select the field
- Switch to the Code editor and paste in some html, e.g.
<p><iframe src="https://www.google.com/maps/embed?pb=[google-maps-link]" width="600" height="400" style="border: 0;" loading="lazy" allowfullscreen="allowfullscreen" frameborder="0"></iframe></p>
Switch back to the WYSIWYG editor
Save the document
Expected result
The map is saved and visible
Actual result
TinyMCE:
Switching from Code to Editor shows just a blank box, then even before saving the article the code is reduced to
<p><iframe></iframe></p>
JCE Editor:
The map is visible in the Editor pane prior to saving the article, after which the code is stripped out entirely
System information (as much as possible)
J4.1.2
Additional comments
It does the same with the 'RAW html' setting

In my original post, you will see that I said "If using TinyMCE, ensure 'iframe' is removed from the list of prohibited elements in the plugin settings" which is what I did.
Switching to Joomla text filters makes no difference as super users have no filtering applied.
I have since discovered that TinyMCE (but not JCE) is stripping all tags except for the first and last, e.g:
<p>This is some text</p>
<p>This is some more text</p>
becomes:
<p>This is some textThis is some more text</p>
UPDATE: this is very odd, as switching to Joomla text filters is now working as it should, but it still doesn't explain why it doesn't work the other way. New users to J4 wouldn't have a clue as there are no hints to what "Use Joomla Text Filter" means.

This is the intended and expected behaviour
Look at the tinymce plugin and you will see that by default it prevents iframes
Either change the behaviour here in the tinymce editor plugin OR what I do is to change tinymce to use the Joomla Text Filters in the global config so I am only managing them in one place.
