Normally when I make a site I use an editor I made with the help of Demonslay that has buttons to do the html fucctions like <p></p> extra. But I have been reading on php.net if there is a way to do away with this editor and have it so if that a person presses enter it adds a new line thing in the code and if shit + enter a new paragraph.
After a heap of reading (so many commands on php) I could not see anything obvious that would get this.
Anyone have any ideas how I could make this happen?

Yeah sounds the ticket.
I like the looks of this one.
But how it all works in a form is a little over the head. Been having a play and nothing worked. I get there I guess. hehe

<?php
function nls2p($str)
{
return str_replace('<p></p>', '', '<p>'
. preg_replace('#([\r\n]\s*?[\r\n]){2,}#', '</p>$0<p>', $str)
. '</p>');
}
?>

Ok how do these work with a textarea? I replaced the $str with the area ID and nup.. I don't understand how to get these to look at the textarea.
Do I need to place an echo somewhere and if so echo what?

What?
When you are using nl2br(), this is when you are processing the code. If a user presses enter inside of a textarea, it already adds a newline, and visually, they are on another line, or another paragraph. Same way that you are using the editor when you are posting a reply. When I submit this with enter spaces, they are newline characters, and the forum processes them into HTML breaks (<br />), thus keeping the same intended outline of paragraphs.
Also note that you should actually use nl2br() when you are outputting the code, and not storing it like that in the database. This can be fatal, when you goto use something like htmlspecialchars() before outputting... so use nl2br() as the last cleaning function.

Ahh so now I get it.. so you enter the text into the database with the blank lines, and when VIEWING is where you execute the nl2br. This the correct understanding?
If not will just use my buttons you help me with hehe.
By gosh I got it!
Awesome
