If I take get_magic_quotes_gpc() into consideration it now works fine
except for line feeds and carriage returns.
if (get_magic_quotes_gpc()) {
$sq = stripslashes($_POST['Summary']));
} else {
$sq = $_POST['ShortDesc'];
}
$Summary = mysql_real_escape_string(strip_tags(trim(urldecode($sq))));
This code works for quotes en uri's. But whatever combinations I've
tried including using nl2br on storing and/or retrieving. It doesn't
work for line feeds and carriage returns.
Either \r\n is displayed on webpage or rn.
How to correctly store and retrieve input from a textarea (with LF and
CR) in MySQL ?
