About the getvar/getvars/postvar/postvars Functions
These functions, defined in INC/GETPOST.PHP
, have been designed and re-designed and re-re-designed too many times. Finally, it is best in their simpilest form:
function postvar($var) {
return (isset($_POST[$var])) ? $_POST[$var] : '';
}
That may seem silly at first glance, but the result is an overall reduction of complexity for the if is set read else empty
code is then in a single location in the code and not scattered throughout.
