Converting Textarea Return Characters To <br />

Hi guys,

I have set up a form with a textarea. If I have text on multiple lines such as:

CODE

here is some content

here is some more content

then when I print it out as html it will be returned on one line like so:

CODE

here is some contenthere is some more content

When i look at the content in the database it looks just like the original way i entered it (contains the multiple lines).

Is there a function in php so that when i spit it out in html it retains the multiple line format?

Thanks in advance.

try this:

CODE

$value = str_replace(array( "\r", "\n", "%0a", "%0d"), ' ', $value);

that may be sorta complex.
The easiest way is to use :

CODE

<?php
$line_break=nl2br($_POST['text']);
echo $line;
?>

nl2br() is a function which inserts a <br /> automatically at the end of every line.

CODE

$value = str_replace(array( "\r", "\n", "%0a", "%0d"), ' ', $value);

I use that in a function that replaces all the bad stuff in Emails, Comments, $_POST arrays, etc.
Yes, probably a little overkill checking for the hex values. And you are correct, the nl2br() would likely do it.

I'm not sure if I understand your problem, but try using strlen($str), where $str is the textarea value.

Oh thats really simple!

you can replace newlines using str_replace

like this

CODE

$your_string = str_replace(array(chr(10), chr(13)), "<br />", $your_string);

or you can use nl2br

CODE

$your_string = nl2br($your_string);

BUT if you are showing html code anyway, you can write it in a textarea

like : <textarea><? echo $your_string; ?></textarea>

or using the <PRE> tag, like this:
<PRE><? echo $your_string; ?></PRE>

But there are more options afcourse
Thats it!

There's a very useful function in PHP to handle this situation. The function is "nl2br()", try it and you'll find how cute PHP is
