Replacing <p> tags

[skippt]

Hi,

I'm trying to replace <p> tags and replace it with a contenteditable div.

$newpost = str_replace("<p>", "<div contenteditable=\"true\"><p>", $post);

This code works fine however I'm using javascript setInterval to periodically update to a database through ajax and while it doesn't conflict with javascript when I refresh the page it inserts a second string replace.

eg.
On first refresh it enters

<div contenteditable="true"><p>

On second refresh it enters

<div contenteditable="true"><div contenteditable="true"><p>

On third refresh it enters

<div contenteditable="true"><div contenteditable="true"><div contenteditable="true"><p>

I've tried replacing the <p> with <P> or <p class="paragraph"> and str_replace instead of str_ireplace but I still get the same result.

Does anyone know of any way I can only have it replace once?

Though not the best solution, this should work:

$newpost = str_replace("<div contenteditable=\"true\"><p>", "<p>", $post);
$newpost = str_replace("<p>", "<div contenteditable=\"true\"><p>", $newpost);

EDIT: Actually, your other idea should work:

$newpost = str_replace("<p>", "<div contenteditable=\"true\"><p class=\"paragraph\">", $post);

How about:

$newpost = str_replace("<p>", "<div contenteditable=\"true\"><p data-contenteditable >", $post);

Why u r not using if condition :

if(preg_match('/<div contenteditable="true"><p>/', $post)) {
   $newpost = $post;
}
else {
   $newpost = str_replace("<p>", "<div contenteditable=\"true\"><p>", $post);
}
