WP E-Commerce Pagination Fix

Little about WP E-Commerce

WP E-Commerce have become a very useful and popular plugin for shopping carts on WordPress based Web apps. It’s now been there from long time but still the issues are there, but overall I like this plugin and its extremely useful. As by using this plugin one can be up and running with an online store withing no time.

The Problem

In recent days one of my client upgraded version of WP E-Commerce to 3.8 which I was expecting will resolve all the pagination issues but it didn’t, my client got issues with Search and tagged pagination (as if we click on page number it was leading to product’s page and was not redirecting to actual page). So let me tell you clearly what was happening:

My client is using SEO friendly URLs i.e. (Settings >> Permalink Settings >> Custom Structure = ‘%postname%’) which means the following:

http://www.yourdomain.com/?p=123 will become something like http://www.yourdomain.com/sample-post/

Which means my main product’s page was accessible through this link https://www.mydomain.com/products-page/

Pagination on this link was working correctly, but the problem was actual arising on search results and tagged results.

Problem with Search Results and Tagged Results Pagination (/s=search+for+product, /tagged/tag-name/)

http://www.mydomain.com/s=search+for+abc (So someone searched something from site), but if the results are too many and pagination is enabled the customers where badly redirected to wrong page when they click on any page number generated by WP E-Commerce. So when I was clicking on pages I was redirected to this link http://www.mydomain.com/products-page/page/2/ (But look this is wrong, I’ve been redirected to product’s page 2 not the search results page 2, and where have the search term gone?). The similar problem also was arising on tag URL i.e. http://www.mydomain.com/tagged/tag-name/ (So someone is looking to explore some tag).

The Solution (1+1 = 2)

Go to WordPress >> wp-content >> plugins >> wp-e-commerce >> wp-includes.

First Data API Integration to PHP Code

20 May

Requirements

On your hosting you should have following requirements fullfilled:

SSL Certificate should be installed.
You should have 1129 port opened (If not opened ask your hosting to open it).
Make sure the version of PHP is greater than 4.0.2. (Can check it by phpinfo function)
PHP compiled with both cURL and OpenSSL. (Can check it by phpinfo function)
Login in to https://www.linkpointcentral.com/.
Go to Download Center.
Download your Certificate for the API. (will be having extension of pem)

Now you are done for running a test script on your server. You’ll require following lphp.php file to run the script.

Now we are going for the actual code called as PASS_XML.phpto be tested using lphp.php file.

I got this file from First Data examples but I modified it so now its working.

<?php

# PASS_XML.php - example of how to send and recieve an XML string
#
# In this sample, the merchant would be doing their own XML encoding/decoding
#
# This sample does only a minimal SALE transaction, but it can be
# used as an example of passing in larger XML strings for more complex
# transactions. Any of the included LinkPoint XML sample files could be
# passed in as an XML string here.
