PHP Validate Form

Making the form on the php impressed casual. But one time we faced a problem with the validation of that form, eg filling of data can not be empty. Here are some scripts that can be used to check the validation of a form, especially checking space which can become the things we missed.

To make it easier, can be made a separate file with the parent file. suppose check.inc and later called in the php file using the command required


function check_not_empty($s, $include_whitespace = false)
{
if ($include_whitespace) {
// make it so strings containing white space are treated as empty too
$s = trim($s);
}
return (isset($s) && strlen($s)); // var is set and not an empty string ''
}
?>
