Which file ?

Also, this will be server side validation so customer will be able to make a request using invalid zip-code. We can use this but I think there should be JAVASCRIPT validation before making this request.

Can you tell me the exact path for this hook ?

Hi,
I installed V 1.13 and on create account page how can I add validation for Zip code to accept only numbers and limit 5 digits only
I can do this via Jquery in create.tpl but is there any other way to do this without editing code ? Same for phone number and other fields.

Hi Developers,

I have a suggestion for some CSS and JS file that customers doesn't have to clear cache when they make changes to it.
You can add a flag (toggle button) in system->setting somewhere and if it is turned ON then update the code https://github.com/abantecart/abantecart-src/blob/master/public_html/storefront/view/default/template/common/head.tpl#L50 so that it adds current time stamp every time it refreshes
<link href="<?php echo $this->templateResource('/stylesheet/style.css') . "?v=" . date("YmdHis"); ?>" rel="stylesheet" type="text/css">
Once users are done testing their changes they can simply turn OFF that button and then timestamp will be removed something similar as what you already have for if($faster_browser_rendering == true) { .. }
I am a developer and I use this so I don't have to clear cache explicitly after every change and once I am done I can simply turn it OFF

This is just a suggestion as I know it will slow down rendering css / js file but user can turn it ON and OFF.

When I change order status of customer from pending to processing and select notify customer it doesn't send BCC to all other emails who should be getting alert emails.
I have 2 other emails added to system->setting->mail (Additional Alert E-Mails also alert email is turned ON) they do get new order emails but no emails for status changes. We want to see what exact email was sent to customer and to keep in our record thats why.

I have a contact us form where customer enters their firstname, lastname, inquiry, email and phone number and they all are compulsory but when we get email it only comes with last name, inquiry and phone number I also need email and firstname.
All those fields are compulsory and I have checked it on my form it says controller Contact us page. Same issue with the email we get when someone fills out contact us for we don't get other details.

Did you make any changes in your .htaccess file ?
or something else on server got updated / changed ?

As you have made changes in core files which might change when there is a new update so its better to create your own custom extension like you can see abanteCart has some extensions by default so make one with your changes and when there is a new update for abanteCart your code won't be affected
read here http://marketplace.abantecart.com/extension-developer-help  and  https://abantecart.atlassian.net/wiki/spaces/DOC/pages/17727622/Extension+s+Developer+Guide

For example payPal extension is not affected when AbanteCart makes new update as that code stays in separate directory and can interact with different table

You should create a new extension with all your changes then install it where ever you want and don't worry about AbanteCart's update

Hi I exactly did this but I am getting errors as mentioned above. I can not update to latest version as I have lots of custom coding in my version and I am working locally as of now.
Please look at the errors I have mentioned above.
