TinyMCE executes HTML tags - how to stop it?

I'm trying to include simple code samples in the TinyMCE editor. It looks fine when I'm writing it and when it is saved in the MySQL database. But when loading it in the TinyMCE editor once again the HTML-tags seems to be executed, even though they are saved as HTML names and not the actual tags.

For example if I write

<b>test</b>

In the database this was exactly what was stored, but when loading it in the TinyMCE editor, it now looks like

<b>test</b>

And if this is saved and loaded one more time it turns into

test

So it seems like TinyMCE is executing the tags, even though they are not actual tags to begin with. Does anyone know why this is happening?

I have tried to add the pre-tag and code-tag around the code, but it seems to be ignored by TinyMCE. I've also tried to add

preformatted : true,
verify_html : false,

to the TinyMCE init-function.

Any help would be greatly appreciated. Thanks.

Solution

  • I found out this is not a TinyMCE problem, this is just how textareas work. I used the PHP function htmlspecialchars() and everything is now working as intended.

    <textarea><?=htmlspecialchars($content)?></textarea>
