im working on a comment/forum app and when a user enters too many
carriage returns i want to remove them before insert to db.
example, user input:
-----snip-----
[quote=user]
foo
[/quote]
<bunch of extra lines>
more text...
-----snip-----
I to change to:
[quote=user]foo[/quote]
more text...
i try this regexp:
$message =
preg_replace('#(\[quote(=("|"|\'|)([^\]]*)\\3)?\])\s+#i', "\\1\n",
$_POST['message']);
doesn't remove / replace anything.
I need for it to work when they use [quote=xx] or [quote] and ends with
[/quote]
any help?
$str= preg_replace("%(\r\n|\r|\n)%", "\n", $str);
$str= preg_replace("%\n\n+%", "\n\n", $str); //max 2 \n
