I have a form that asks to enter one or more paragraphs

The problem is when you submit it, if you have a line break, it adds "rn" instead of "/r/n"

I am not cleaning the variable at all... here is a simple version of the script

PHP Code:

if(!isset($_POST[submit]))
    {
    echo "<form method='post' action='http://www.cnotecreations.com/webmanager/mairsfamily/index.php'>";
    
    echo "<textarea name='paragraph' rows='7' cols='35' />$getmain3[paragraph]</textarea>";

//$getmain3[paragraph] is defined earlier in the code

    
    echo "<input type='submit' name='submit' value='Submit' />";
    echo "</form>";
    
    }
    else
    {
    echo $_POST['paragraph'];
    } 


So for exapmle if i type in the following:
"Line
Beak
Test"

The output ($_POST['paragraph']) is equal to:
"linernbreakrntest" with no slashes

Thanks in advance for any help.

If you echo this back to browser then it's no wonder that there are no line breaks. In html line breaks are not simply \r\n but <br />. Either use nl2br() or wrap the output into <pre></pre> to keep line breaks.

The original code updates that field to a database and use BBCode later on to insert it into the html, but the BBCode does not work when the line break is defined as "rn" why is there no slashes?

The only reason i am printing it to the screen is so i can play around with some stuff and see if the problem is fixed without having to check the database.

have you tried mtishetsky suggestion of nl2br()
