CKEditor and {cke_protected} for "<?" string

[lkopo]

If I try, to write "<?" code into my CKEditor, it will be transformed into

<p>&lt;? lol</p>

It's OK. But if I submit my form and page is reloaded I will see:

<p><!--? lol</p--></p>

That's because your page does not encode content when outputting it to textarea.

This will work correctly:

<textarea class="ckeditor">
&lt;p&gt;&amp;lt;? lol&lt;/p&gt;
</textarea>

This will not:

<textarea class="ckeditor">
<p>&lt;? lol</p>
</textarea>

Because when CKEditor tries to read content from the second textarea it gets:

<p><? lol</p>

And that simply isn't correct HTML.

But it does automatically. How can I fix that? I have to use htmlspecialchars() ?

Your system has to replace every:

• < with <
• & with &
• > with >

when printing textarea's HTML.

Thanks, now it works correctly
