Reason: bad code
----
i worked on a calculator so the user-input could be zero -> couldn´t use !empty() cause it
returns FALSE on those. but i was also too lazy to write:
if(isset($_GET['var']) && $_GET['var']!='')
so i wrote this function:
function cuv($varname,$postget=1)
{
if($postget)
{
if(isset($_POST[$varname]) && $_POST[$varname]!='') return (bool) 1;
else return (bool) 0;
}
else
{
if(isset($_GET[$varname]) && $_GET[$varname]!='') return (bool) 1;
else return (bool) 0;
}
}
so to check GET vars i only have to write:
if(cuv($varname,0))
and for post vars only:
if(cuv($varname))
