Why does my <pre> tag get moved by TinyMCE?
I'm using TinyMCE as a text editor and it's working great except for one very weird anomaly.
This is what I'm inserting:
<div class="code_frame">
<div class="inner_code_frame" style="margin-top: 5px;">
<div class="paper">
<pre style="font-family: arial; font-size: 9pt;">
<html>
<table>
<tr>
<td>
hello
</td>
</tr>
</table>
</html>
</pre>
</div>
</div>
</div>
This is what gets inserted...
<div class="code_frame">
<div class="inner_code_frame" style="margin-top: 5px;">
<div class="paper">
<table>
<tbody>
<tr>
<td>hello</td>
</tr>
</tbody>
</table>
<pre style="font-family: arial; font-size: 9pt;"> </pre>
</div>
</div>
</div>
Notice how <pre style="font-family: arial; font-size: 9pt;"> </pre> has gotten completely displaced?
Why?
And how do I fix that?

Leak!
I was able to do a little more research since posting the question and here's what I found...
This gets inserted into the database correctly:
It's not that the content as it was entered into the database is wrong. That piece is fine.
But when I go to edit it and ask TinyMCE to reproduce what's in the database, it's then that the <pre> tag gets moved.
I'm looking at this: https://stackoverflow.com/questions/56407393/why-does-tinymce-move-content-out-of-precode-tags-or-auto-close-the-tags
..and other such resources and it seems like < confuses TinyMCE and it wants to see &lt;, otherwise it assumes it's a mistake.
Any ideas?

Basically, I want TinyMCE to recognize < and > as legitimate characters and not assume they're mistakes...at least that's where I think the problem lies.
Hi Bruce,
from my example, I don't see anything moved out

Hey, Leak!
I don't you would see anything moved out...at least not based on what I can see in your example.
Take a look at this...
When I submit some content using this:
...and echo out what the database is receiving from this interface, I get this:
But, when I go to edit it and ask TinyMCE to render what's in the database, it's then that my <pre> tags get moved, and I wind up with this:
Do you smell it?
The characters in the database are accurate, but TinyMCE sees "<" as a mistake and that's when things are getting moved around.
I'm showing you the Source Code of what's in the editor when I ask to see it before I try to edit it, but look at the way it shows up on the screen...
There's no code. Only what TinyMCE assumes is a mistake, so it renders it as a table.
But I think I know how to get around this.
I need to replace all of the < and > characters with &< etc in between the <pre> tags.
I was looking for a script that would accomplish that and I tried this, but it didn't work:
$search = "/[^<pre style=\"font-family: arial; font-size: 9pt;\">](.*)[^<\/pre>]/";
$replace = $super_string;
$string = $row['content'];;
echo preg_replace($search,$replace,$string); */
Any ideas?

But, when I go to edit it and ask TinyMCE to render what's in the database, it's then that my <pre> tags get moved, and I wind up with this:so it go out well from database but the process that set the tinymce content do something wrong
In my example, the content is the one you're describing
so I'm (and look like you let me alone on that) think you set the tinymce content a different way than me
this is the part of the code missing in your posts : from the database, how do you set the tinymce content??
one more time, in my example I use a string, set the content with that string (the same as your database) get the content out and the string seems to match with what I get out.

OK, let me explain back to you what you're describing and tell me if I'm correct.
This is what you have on your Fiddle:
So, you're introducing an additional "layer" before you actually insert it into the TinyMCE editor, yes?
OK, I'm going to try that.
One thing...
I'm a pig on roller skates when it comes to certain aspects of JQuery.
You've got this:
<textarea id="desc_area"></textarea>
<div id="html" style="display:none;">
<div class="code_frame">
<div class="inner_code_frame" style="margin-top: 5px;">
<div class="paper">
<pre style="font-family: arial; font-size: 9pt;">
<html>
<table>
<tr>
<td>
hello
</td>
</tr>
</table>
</html>
</pre>
</div>
</div>
</div>
</div>
<script>
let x = tinymce.init ({
selector: '#desc_area',
inline: false,
force_br_newlines: false,
force_p_newlines: true,
forced_root_block: '',
menubar: false,
plugins: [
'advlist autolink lists link image charmap print preview anchor',
'searchreplace visualblocks code insertdatetime media contextmenu'
],
toolbar: 'insertfile undo redo | bold italic | alignleft aligncenter alignright alignjustify | outdent indent | link image'
});
x.then(function(a,b,c) {
tinymce.activeEditor.setContent(document.getElementById("html").innerHTML);
b = tinymce.activeEditor.getContent();
alert(b);
});
</script>
x.then - this is a "promise" dynamic (https://stackoverflow.com/questions/5436327/jquery-deferreds-and-promises-then-vs-done). What you're saying is that if the previous code hasn't gone south, to proceed with the following condition, correct.
You've got three arguments in your function: a, b and c. I don't see "a," although I'm tempted to believe it's the actual editor, yes?
"b" is the portion that's actually getting the content, but I don't understand the "alert." I don't see a pop up on your Fiddle. What is that?
And then, "c..." I don't see that at all.
Can you break it down for me?

Leak!
That did it! I got it done!
Here's the way it went down...
In the header, I look to see if we're editing a page. If so, we initiate tinyMCE in a way where it knows to grab the content from the hidden div that you suggested. By doing that, all of the previous errors and inconsistencies are solved!
If we're not in "Edit" mode, than a regular startup is initiated and we're good to go.
Just in case anyone else runs into this issue, here's the way it looks:
