Opencart结账不通过自定义字段

Question

I'm trying to add 2 custom fields to the checkout (one for a gift note, one to let users choose the dispatch date). I managed to get the gift note field up and running fine but I'm having trouble with the date field.

I'm using a standard text field (input type="text") with the intention of using jQuery UI for the date picker, but the value of the text field isn't being passed through. If I change from an input to a textarea the data does get passed through. I'm trying to add them both in the 'Payment Method' stage of the checkout on Opencart 1.5.4.

I'm new to Opencart (started looking at it yesterday when I was asked to add these fields) but understand the MVC+L pattern and, as I say, managed to get one field working and passed into the database. I'm not using vQmod.

The data from the input field just isn't getting passed into $this->request->post in controller/payment_method.php

This seems like a bug to me, is it just a quirk of Opencart? I could technically use a textarea if there isn't a solution but that feels a bit of a dirty way around the problem

Answer 1

I found the solution in my case, here's what I did in case it helps anyone in the future.

I found that all the AJAX for posting data through is in

view/theme/THEME-NAME/template/checkout/checkout.tpl

I searched for instances of 'post', checked and checked which section they were relevant to. In my case (adding fields inside the payment_method section), the URL the data was being passed to was

index.php?route=checkout/payment_method/validate

and just added the id's of the extra fields into the data attribute of the AJAX call.

Hope this is of use to someone else
