Create mask for textbox?

[RiGGa]

Hi,

I am creating a form in php and one of the fields will be prompting the user
to enter a time in the HH:MM format, is there anyway using php to create an
input mask so it appears as __:__

Or is there a better way to do this?

Many thanks

No ... well ... almost no, certainly not the way you want it :-)

The HTML form (probably built with PHP):

<form method="POST" action="somethi ng">
<!-- ... -->
Enter time in the "HH:MM" format:
<input type="text" name="time" value="__:__" />
<!-- ... -->
</form>

And the script that receives the form:

<?php
/* ... */
$valid_time_inp ut = false;
if (preg_match('/^\d{2}:\d{2}$/', $_POST['time'])) {
if ($_POST['time']{0}*10 + $_POST['time']{1} < 23) {
if ($_POST['time']{3}*10 + $_POST['time']{4} < 60) {
$valid_time_inp ut = true;
}
}
}
if (!$valid_time_i nput) {
/* wrong input */
/* resend the form, possibly with an error message */
} else {
/* input ok */
/* continue the script */
}
/* ... */
?>

I think you want to do it with JavaScript.
