Postcode Req in "Guest Checkout"

I want to "enable" this feature in Admin under options but before I do I would like to make the postcode be a "required" field to fill out due to being in the US.

Can someone tell me where and what file to edit as well as what lines to add or change?

Thanks

You have to make changes in 3 files to make postcode required in guest checkout

1.)
goto catalog > language > english > checkout > guest.php

Here enter postcode error flag message text:-
$_['error_postcode'] = 'Enter Postcode';

2.)
goto catalog > controller > checkout > guest.php

Find: private function validate()
here enter following code to make validation check:-

if ((strlen(utf8_decode($this->request->post['postcode'])) < 1)) {
$this->error['postcode'] = $this->language->get('error_postcode');
}

Then Find the error display blocks on the page and add the following code to show error message:-

if (isset($this->error['postcode'])) {
$this->data['error_postcode'] = $this->error[postcode'];
} else {
$this->data['error_postcode'] = '';
}

3.)
goto catalog > view > theme > default > template > checkout > guest.tpl
Find code block:-
<tr>
<td><?php echo $entry_postcode; ?></td>
<td><input type="text" name="postcode" value="<?php echo $postcode; ?>" onblur="getMethods();" /></td>
</tr>
Replace it with:-
<tr>
<td><?php echo $entry_postcode; ?></td>
<td><input type="text" name="postcode" value="<?php echo $postcode; ?>" onblur="getMethods();" />
<?php if ($error_postcode) { ?>
<span class="error"><?php echo $error_postcode; ?></span>
<?php } ?>
</td>
</tr>

Hope this will help you.

Almost all Forums have code tags... You think it'd be commonly known by now

I did all the code but how do you make the "red" asterisk show up next to "postcode"?

This code should be the following (opposed to the code above)

Sweet thanks!

In reply to SSJL

it should be this on 2.)

if (isset($this->error['postcode'])) {
$this->data['error_postcode'] = $this->error['postcode'];
} else {
$this->data['error_postcode'] = '';
}
