hey guys... what im looking to do is let users enter a time via text box so 10:36.2 for example



currently i have

<?php
if (($_POST["pb"] == "") || (!preg_match(???????, $_POST["pb"])))
{
    $error['pb'] = true;
    $print_again = true;
    $message = "The pb was not in time format.<br>";
} ?>

 

but what would go in ??? to allow 1234567890 and ":" and "."

would it be something like

 

 

 

 

<?php

if (($_POST["pb"] == "") || (eregi_replace("([0-9]:,.)")

{

    $error['pb'] = true;

    $print_again = true;

    $message = "The pb was not in time format.<br>";

} ?>
