Well, I wanted to know, how could I make the person submit form only within 5 minutes.
<?php
$nome = $_POST["nome"];
$locutor = $_POST["locutor"];
$texto = $_POST["texto"];
$coment = "INSERT INTO 'pedidos' ( 'nome' , 'locutor' , 'texto', 'data' , 'id', 'num' ) VALUES ('$nome', '$locutor', '$texto', now(), '', '')";
mysql_query($coment);
?>
