检查时间以允许在PHP（和javascript）中填写表单

Question

For a website, we have a form where a client enters in their ID number that sends them to a new page that allows them to make a request for our services.

We want to change it so that clients can only request our services from Tuesday-Friday from 12pm - 4pm. If they try to enter their id number during a time outside of Tuesday-Friday from 12pm - 4pm, it will tell them they cannot request our services.

What I want to do is that if the user accesses the page during times when they cannot make a request, an alert box (through javascript) will pop up telling them that. I also want to code something so that if they try to progres forward (clicking the create request button), they will not (though php).

I'm not sure how to check these times with PHP and Javascript in order to accomplish this. If anyone has any insight in how to do this, that would be fantastic. Thanks!

This should work:

<?PHP
$dayOfWeek = date("w");
$currentHour = date("G");

if ($dayOfWeek >= 2 && $dayOfWeek <= 5 && $currentHour >= 12 && $currentHour <= 16) {
  // Show Form
}
else {
    ?>
    <script>alert('Form only available Tuesday - Friday, 12:00pm to 4:00pm');</script>
    <?PHP
}
?>

For more information on PHP's date function, see: http://us1.php.net/manual/en/function.date.php

"G" = 24 hour format without leading 0's

"w" = Day of week, 0 = Sunday, 6 = Saturday
