Project Description:
I need this to work, its already in system but it wont affect the code as it should. Should be a easy fix and would like to have it done right now.
if(isset($_POST['change'])) {
$result1 = mysql_query("UPDATE hosted SET code=replace(code, '$_POST[currentwidth]', '$_POST[replacewidth]')", $db1);
$result2 = mysql_query("UPDATE hosted SET code=replace(code, '$_POST[currentheight]', '$_POST[replaceheight]')", $db1);
$num = mysql_affected_rows();
$message = "$num codes have been affected!";
}
