How To Autodetect Paragraph Breaks

[garethppls]

I have a form but I want to disable HTML. the problem with this is the form doesn't recognise paragraph breaks. any way of doing this like on this forum.
thanks,

is your answer in one of these 3?

<?php
$text = '<p>Test paragraph.</p><!-- Comment --> Other text';
echo strip_tags($text);
echo "\n";

// Allow <p>
echo strip_tags($text, '<p>');
?>

The above example will output:

Test paragraph. Other text
<p>Test paragraph.</p> Other text

<?php
$new = htmlspecialchars("<a href='test'>Test</a>", ENT_QUOTES);
echo $new; // &lt;a href='test'&gt;Test&lt;/a&gt;
?>


<?php
$str = "A 'quote' is <b>bold</b>";

// Outputs: A 'quote' is &lt;b&gt;bold&lt;/b&gt;
echo htmlentities($str);

// Outputs: A 'quote' is &lt;b&gt;bold&lt;/b&gt;
echo htmlentities($str, ENT_QUOTES);
?>

You'll want to lookinto nl2br function ie:
[code]<?php

$str = "this text\nhas line\nbreaks in\n it!";

// convert carriage returns into line breaks (<br />)
echo nl2br($str);

?>[/code]

Also if you want to only allow paragraph tags you can use a function called [a href=\"http://www.php.net/strip-tags\" target=\"_blank\"]strip_tags[/a]. For example:
[code]<?php

$str = "this text<p>is only <b>allowed</b></p>paragraphs!";

// strip all tags from $str but keep < p></p>!
echo strip_tags($str, '<p>');

?>[/code]

Hope that helps.

no I want it to detect paragraph breaks in a form without putting <p> in , just like this forum as its a forum script i'm making

User eregi or eregi_replace to do something like...

eregi("\n\r", $string);

[garethppls]

what if \n or \r arent contained in it?

One thing I've noticed is that with <input type="text"> tags in HTML when they are submitted to a database (like MySQL) it will read the carriage returns and store them properly.

Using echo nl2br($string); works fine when outputting what was in the database and putting in the paragraphs properly. Seems to be fine for windows/macs/un*x type plateforms.

*edit ok that is cool, the forum read my input tag and displayed it hehe

thanks Sharkbait will try that now

[garethppls]

yep that worked thanks sharkbait. I used nl2br before inserting it to the MYSQL but its all good :)

Isn't that what I suggested in my post above? Prehaps I didnt explain it very well.
