nl2br

[mafkeesxxx]

Hello!

I have made a form with a comment field. Now i want to apply the [b]nl2br[/b] string to my comment field. I've tried some things, but didn't work. How can i do this?

This is my HTML:

<textarea name="Comments" cols="60" rows="15"></textarea>

Thanks in advance.

nl2br should be used when you want to print the line out to view it.

The comment field will be send via e-mail.

So i want to apply nl2br to the field, otherwise i recieve the mailed comment field without enters <br>

Here is a little example:

[code]<?php
$var = $_POST['mail']; // something from form
$mail = nl2br($var); // add nl2br to it
?>[/code]

WHy do people do that! I dont get it. Just do:
[code=php:0]$mail = nl2br($_POST['mail']);[/code]

Well you are right wildteen88 :)

[hostfreak]

wildteen88, why does it matter? It is personal preference. It may not be the most efficient way, but it works.

Ok, Thanks for all your help, but probably is a bit more complicated.
I have a mail form wich is HTML with mail.php included.

This results in a HTML template that is send via mail and recognises the form fields like this {Comments}

Now i want to apply the nl2br to the {Comments}

Damn, LOL  ;D ???

Hope you understand  :-\

[JasonLewis]

ok. first off. what the others said is correct. {Comments} would be a variable.

so you would do:
[code]$comments = nl2br($comments);[/code]

or you could do this, but its easier to do the above:

[code]$comments = str_replace("\n", "<br>", $comments);[/code]

[b]Ok, still doens't work, this is my mailscript. Hope you can help me now!  :)[/b]

Should work? You don't need to make it a variable.

I don't know what version of PHP you're using, but mine requires you to assign it to a variable, unless you're echoing it directly :D

[code]
<?php
$comments = <<<EOT
This is line one
This is line two
This is line three
EOT;

// This will print on one line
echo "$comments";

// This will print on one line
nl2br($comments);
echo "$comments";

// This will print on multiple lines
echo nl2br($comments);

// This will print on multiple lines
$comments = nl2br($comments);
echo "$comments";
?>
[/code]

Thanks,

But i don't know how to apply it to the script i posted above.

The function nl2br() does not change the argument, it returns the modified string, so a statement like:
[code]<?php nl2br($str); ?>[/code]
by itself does not do anything. You need to either echo the result or assign the result to a variable.

Also, using double quotes around one variable when you're doing an echo are not needed. The following two statements will produce identical output:
[code]<?php echo "$string"; ?>[/code]
[code]<?php echo $string; ?>[/code]

Find this line in your code:
[code]<?php
$MailBody =  $TemplateData;
?>[/code]
replace it with:
[code]<?php
$MailBody =  nl2br($TemplateData);
?>[/code]
