iframe gets removed from wysiwyg field

[dicabrio]

I have a page with a text field that is displayed as wysiwyg editor (tinyMCE). When I add some source code like <iframe src="//www.youtube.com/embed/EdNWOlnGtrk" width="560" height="315" frameborder="0" allowfullscreen="allowfullscreen"></iframe>. Save the code then save the page the iframe is removed. If I do it again (add the iframe to the source code) then save the page. The iframe is there on the frontend. If I then save it again it is removed again. It looks like not being a setting of tinyMCE, but I'm not sure.

Hello @dicabrio,

I think the Iframe gets stripped out by the Purifier feature in the textarea field settings:

Personally I would not disable this feature and use Hanna Code instead: https://processwire.com/modules/process-hanna-code/

It seems silly, because I do the following

- Open page

- Add iframe

- Save page

- Iframe gone on the rendered page

- Add iframe (the edit page was still open)

- Save the page

- Iframe is visible on the rendered page

- Change something on the page in the CMS (kept it open)

- Save the page

- iframe gone

 

So this keeps on repeating. Hanna Code is not a solution for this problem at the moment as I have a lot of content already with iFrames.

If you disable the Purifier feature, the iframe should not get removed.
I have tested this by manually adding an iframe in the source code view.

I would recommend you keep your iframe seperate from your other content. Make two fields. Check the Settings for each.

1. For the iframe, use a Textarea without any Text Formatters. You can echo this on the frontend and get the exact HTML code you put in that field.
2. For content with HTML markup, use a Textarea with the HTML Entity Encoder Text Formatter.

I use this approach all the time for any kind of embed codes. You can treat iFrames in a similar manner.

Yes tried it myself. Works by disabling the purifier. In that regard something is still going wrong. If I enable purifier the iframe is stripped only sometimes and not always. So something is happening there. @Inxentas keeping iframes separate from the content, as I do agree, is not an option at the moment.

Can I ask why that is not an option? Perhaps that issue is solved more easily.

[dicabrio]

Oke.. yes it is an option, but I don't want it to be an option at this point in time as it is more work. I'm migrating from an old CMS. I just copy the content from an old wysiwyg editor.
