Debugging Prestashop Templates
While stumbling around the internet as you do when pondering a particularly awkward programming challenge, I came across an excellent post on smarty debug with FireBug. This inspired me to pull together a Prestashop module to allow store owners, designers and developers to view indepth debugging data from right within the Prestashop environment.

Display module output anywhere
Posted by admin | Filed under Development Resources, Tips and Tricks
I came across a post on the Prestshop forum recently that was discussing how to display the contents of a single module on a page. The example proposed worked, but it seems to me that it worked only through sheer luck rather than design as all that was being done was to display a smarty .tpl file. The smarty variables required for the module used in the example were all included as global values, so it worked, but most other modules would need to be able to execute their underlying hook code in order to display anything meaningful.

Resetting your Prestashop
Posted by admin | Filed under Development Resources
I’m not a great fan of commercial software, but there are some tools that are probably worth paying for — otherwise the author wouldn’t be able to maintain the code. I know from personal experience that relying on donations doesn’t pay the bills.
I came across PSE Terminator today and I must say I’m quite impressed. I usually have to do all of this by hand and this tool could save a huge amount of time. I’ll need to start saving up so I can afford to buy it!

Using FirePHP (FireBug) with Prestashop
Posted by admin | Filed under Development Resources, Tips and Tricks
Debugging can be such a pain sometimes…
I’ve been using FirePHP for some time now on my CodeIgniter projects and recently while I was looking at doing some cool things with the product data returned by the Category::getProducts() function it struck me that it would be nice to be able to easily see what data was returned. Why I’ve never used the FirePHP class in my Prestashop projects before I’ve no idea, as it really is very simple to use, if a little erratic in its behaviour….

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.

Writing your own Prestashop Module – Part 5
Posted by admin | Filed under Tutorials
The finishing touches
Introduction
In this final part of our basic module writing tutorial series we’ll look at the final steps to transform our Tutorialthird module class into a base template that we can use to kick start the writing of new modules. Rather than republish the same old code again we’ll only discuss the changes, but I’ve added a download link at the end of this part so you can grab the final code and use it as the basis for your own projects. We’re going to call this module “Skeleton” – a name that we’ll replace with our own when it comes to producing new modules based on it.

Writing your own Prestashop Module – Part 4

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.
