Hi there, I have a form where users input information and will be formating it into paragraphs etc.

I would like to keep this paragraph / line break formating.

Currently I store the txt in my db and when I retrieve it I get everything on one line...

How can I preserve the line breaks the user is keying in on my form?

do I do this when I grab the data from the form or when I output it?

Here is my code :)

[code]

$showme = $_GET['showme'];              // Which Class do I want to see

shocker-z, I apreciate your help but am not sure where to stick this bit of code.. I tried inserting it into the echo but it did not work.

I figure the best place would be in the insert so that I only do it once... can I do this in the query or do I format the variables first. Also can I format all the variables at once or must I do them individualy?

I added [code]if (2 == $what) {
        str_replace("\n","<br />",$class_def);[/code]

which in my html does not give me new lines as I type, but when I choose to edit I see the breaks.

I've edited your code so that all POST variables convert new lines to <Br> this was simplest way of doing it hope this works well mate


[code]<?php

You want to store the information in the format that comes from the user (other than using stripslashes and mysql_real_escape_string) on the data when it is inserted in to the DB.

You want to use nl2br() on the data when it is displayed.
