将PHP html字符串插入TinyMCE编辑器

Im trying to get HTML from my MySQL table inserted into my TinyMCE editor. But I have serious trouble setting up the PHP string into Javascript.

when I just try to insert it like this:

tinymce.activeEditor.setContent("'<? echo $description; ?>'", {format: 'raw'});

It has trouble with the single quotes and the double quotes in the $description variable. I get unidentified id's in my string because the string gets cut off due to the single and double quotes that are located in the string.

How can I insert this into TinyMCE, which ultimately comes down to how to make a HTML string without cutting of early?

You can simply replace those characters:

tinymce.activeEditor.setContent("'<? echo str_replace(array('"', "'"), array('\"', "\'"), $description); ?>'", {format: 'raw'});
