's for line breaks in a form

MarkBad311

Simply I have a form and when users submit a post on my guest book I need when they press enter (line break) in the form that I have to do some kind of preg_replace and replace that linebreak with a break tag.

the variable holding the message is $msg

Thanks in advance for your help!

That's what you need....

If you need it in XHTML format (as your topic title suggests), do nl2br, and then do a simple str_replace():

$msg = nl2br($msg);
$msg = str_replace('<br>', '<br />', $msg);

nl2br() adds linebreaks in the form of , so the str_replace() is unnecessary.

Ah, didn't see that side-note about 4.0.5.... but then again, I haven't looked at that function's manual page since 3.x.... it's just been one of those I know, ya know?

Okay, so just [man]nl2br[/man] is what you're lookin for....

Sorry one more thing. You said that this is from the form.. So I must add this to the form part before the query to insert XHTML line breaks before I instert it to the database. Am I right?

How about after it is in the database whwn displaying stuff that is coming out??? I ask because I already have entries in the database. Is there any ways to change this or should I not even worry about it?

how about instead of I wanted something that added "" This I ask because the way it is set up now the first line of text is indented.

[man]str_replace/man

All "line-breaks" will be \n normally with UNIX, and \r\n with Windows....

str_replace("\n", '</p><p>', $string)

well the line break thing is not working this is BEFORE I insert it in to the Query

//Run Sanitize Function
 $name = sanitize($_POST['name']);
 $date = ($_POST['date']);
 $e_mail = sanitize($_POST['e_mail']);
 $msg = sanitize($_POST['msg']);
 $msg = nl2br($msg);
 $web_site = sanitize($_POST['web_site']);

MarkBad311

 function sanitize($input)
 {
  if(get_magic_quotes_gpc())
  {
    $input = stripslashes($input);
  }
  return(mysql_real_escape_string($input));
 }

Sorry that is my sanitize function too
