Fixed version of the gsitemap module
Posted by admin | Filed under Free Prestashop Modules, Prestashop
There seems to have been a lot of problems with the Google XML Sitemap generator shipping with PrestaShop 1.2, so I’ve had a run through and re-written a fair bit of the code to fix these issues.
The main changes (in 1.4.2) are:
- New XML generation code using the DOMDocument(*) class
- Modified the logic to remove extra elements from the generated URLs
- Added an xml-stylesheet reference to the output file, xsl included in download
- Fixed the issues when “Friendly” urls are turned off
- Add a new field to the cms table on install to track modified dates (auto updating)
- Added removal of additional field on uninstall
(*)If your server doesn’t support this then sorry. Go elsewhere for hosting!
Updated to 1.4.3 — 10 August 2009
- Added error checking and reporting
Updated to 1.4.4 — 18 August 2009
- Added images to the sitemap (as introduced in the 1.4 version in the 1.2.1.0 distribution)
- 1.2.1.0 including fixes to the Link class which broke 1.4.3, so fixed that
- Added cross-compatibility so this version works in both 1.2.0.x and 1.2.1.x
- Fixed a bug when __PS_BASE_DIR__ is set to other than the site root
Example output: with friendly urls and without friendly urls.

AddHeader – a sibling for AddStuff
Posted by admin | Filed under Free Prestashop Modules, Prestashop
Sometimes you just want to do something simple, and there doesn’t seem any way of achieving it easily. Then you find something like AddHeader.
This one adds the contents of your specified file into the header of your pages, so you can add or remove code without having to go and edit the template files (and it’s there regardless of which template you’re using too!). Simple.
Version 0.1.0 (Initial Release August 2009) : AddHeader module

Storing complex configuration data
Posted by admin | Filed under Development Resources
While porting the WP-Cumulus plugin to Prestashop I came across an interesting situation. In the original plugin the parameters for the Flash movie are stored in an array that is obtained from the Wordpress database using a get_option() call. In Prestashop the parameters can be retrieved in bulk using Configuration::getMultiple(), but in that case you have to specify the key names for all the parameters which is a pain.
What I decided to do was to use the serialize() and unserialize() php functions and store the options as a single configuration item in the database. That way we use:
// Get the options $newoptions = unserialize(Configuration::get($this->name.'_options')); // Save the options Configuration::updateValue($this->name.'_options', serialize($newoptions));
The above works great in this situation, as the parameter names aren’t language dependent, but this technique isn’t suitable if your configuration data key needs to be defined in multiple languages.

Moving Boxes Home Featured jQuery module
Posted by admin | Filed under Free Prestashop Modules, Prestashop
I thought it was about time for yet more free Prestashop eye candy, so here’s yet another home featured products module for you all to play with!
Just specify how many products you’d like to feature in the configuration screen and sit back and enjoy! Well, maybe not as I suspect you may also want to play with the css file in the module directory to modify the style to suite your stores. There are also a few images you may want to tweak too!
The javascript and markup is only gently modified from the original obtained from the superb CSS Tricks.
UPDATE: There was a slight error in the uninstall function which resulted in an error when you try to remove it. Updated is available below and should just be copied over the 0.1.0 version to fix.
Version 0.1.0 (Initial Release August 2009) : Moving Boxes “Featured Products” module
Version 0.1.1 (Bugfix Release August 2009) : Moving Boxes “Featured Products” module

PS_Cumulus a WP-Cumulus port to Prestashop
Posted by admin | Filed under Free Prestashop Modules, Prestashop
I was looking to write a cool module to use in future tutorial articles when I came across the nifty looking WP-Cumulus Wordpress plugin by Roy Tanck. It had all the elements I was looking for, and he has kindly released the code (including the flash source) under the GPL license. Approximately 2 hours later PS_Cumulus was born!
Before anyone asks, the name has to use an underscore as a hyphen isn’t allowed in PrestaShop class names….

Writing your own Prestashop Module – Part 4
Posted by admin | Filed under Tutorials
Form Validation and Security
Introduction
While being sufficiently functional for what it does, the module we created in Part 2 does present us with some issues to consider when implementing “real world” modules to extend Prestashop. In particular the user input we captured with our form was written directly to the configuration entry without any checking to determine whether it was valid, nor did we take account of the type of data being entered.
In this tutorial we will look at the general issue of form input checking and security, both for Back Office and Front Office forms and user input as well as looking at improving our code both functionally and aesthetically.

Paypal WPP (Example) – PayPal Direct API
Posted by admin | Filed under Development Resources, Free Prestashop Modules, Prestashop
Development Release
I’ve been asked several times about this, so I guess I’d better release the code. This was written some time ago, and the target PrestaShop version was 1.1, however it should work with later releases.
The archive contains additional code to support PayPal Express Checkout, as this was originally developed as a shared library. A PayPal Express Checkout example will also be published here shortly.
Please note that this is intended for “development” purposes only as an example and was written to test out various concepts in PrestaShop, not as a robust payment method for use in commercial stores.

Storing Module Configuration
Introduction
In the third part of this series we’ll look at how we can store configuration data for our modules in the Prestashop database, and how we can allow users to interact with this data to control the module’s behaviour. We will also briefly touch on how we can generate output from our module to provide visual feedback of the configuration changes.

Creating a basic module
Introduction
In this second part of the series we will look at creating our first basic Prestashop module that can be controlled from the Back Office.
The Module class
Similar to the ObjectModel base class, all Prestashop modules are extended from a common base class used to define their basic functionality. The “Module” class provides the interface between the administration screens and your module as well as providing internationalisation and “hook” management functionality.
