Basic postcode-based shipping?

[Lyte]

Hi, I am wondering if there is any fairly simple way to enable flat-rate shipping of say £5/order for a particular set of about a dozen (local) postcodes.
The option would only display if a customer was local.
I have searched and found this thread, which is a bit brief but kind of like what I'm looking for:
http://www.zen-cart.com/forum/showthread.php?t=110632

I would be quite happy to hardcode the postcodes in but I'm still pretty new to ZenCart and my PHP skills are a bit minimal!

Seems like a lot of people could use this kind of option but there are no obvious easy answers... except I guess Ceon's AdvShipper but I wonder if that would be almost over-complicating things, since I don't want to do anything very complex with other shipping rates.

Thanks in advance for any advice!

well, obviously there was deafening silence in answer to my question above, so I have had to go away and do some thinking and thought I should share...

This is what I have done with DrByte's original code - basically I am now taking off the last 3 digits of the UK postcode to give the outcode (first) part, which will have 3-5 digits depending on whether the outcode is 3 or 4 digits and whether the customer put a space in. Then in $free_ship_postcodes you need to put the list of 'local' postcodes you want to define, both with and without the space.

I think you shouldn't need to include lowercase versions if you use the Capitalize Sign-up Fields mod:

Say for example your postcode list is SG1,SG2,SG3,SG4,SG14,SG15,SG16,AL6,AL7 you need to insert new code (red) as shown below into /includes/modules/shipping/freeshipper.php

Code:

if ($check_flag == false) {
$this->enabled = false;
}

// check to see if postal code is in list of allowed codes:
} else {
$free_ship_postcodes = array('SG1','SG2','SG3','SG4','SG14','SG15','SG16','AL6','AL7','SG1 ','SG2 ','SG3 ','SG4 ','SG14 ','SG15 ','SG16 ','AL6 ','AL7 ');
$customer_postcode = $order->delivery['postcode'];
$check_outcode = substr($customer_postcode, 0, -3);
$valid_digits = in_array($check_outcode, $free_ship_postcodes);
if ($valid_digits) $this->enabled = true;
}
}


Now enable the "freeshipper" module in Admin->Modules->Shipping. I have changed the text in the freeshipper language file so it says 'Local Delivery' rather than 'Free Shipping', since I actually want flat rate.

As far as I can tell, at first glance this seems to work, (thanks a million, DrByte) though I may very well have missed something! Any constructive criticism would be very welcome.

oops, to be technically correct I should have said outward codes will have 2-5 digits depending on whether the outcode is 2, 3 or 4 digits and whether the customer put a space in (I forgot some postcodes were shorter) shouldn't affect anything above tho

if you want to move beyond basic you should have a look at Ceon Advanced Shipper - I use it for all my shipping options, I don't think there is anything more comprehensive.
