Newbie's question-for an explanation of a parameter, I can see an example on the Internet: & lt ;? Php & nbsp; if & nbsp; (isset ($ _ POST [action]) & nbsp; & amp; & nbsp; $ _ POST [action] & nbsp; & nbsp; submitted) & nbsp ;{& nbsp; & newbie question --- explanation of a parameter
For beginners of php, see an example on the Internet, as shown below:
if (isset($_POST['action']) && $_POST['action'] == 'submitted') {
print '';
print_r($_POST);
print 'Please try again';
print '

} else {
?>
}
?>
