onAfterProductUpdate save method

I'm writing a plugin to do some processing tasks on uploaded products. One of the things that I am trying to achieve is to modify the values of custom fields using the onAfterProductUpdate trigger.

I have successfully carried this out with the onBeforeProductcreate trigger but cannot figure out what the correct method is for onAfterProductUpdate

Here is the code I am testing

public function onAfterProductUpdate(&$product) {
	$product->my_field = 'test';			

	//I need to add correct $this->save($product) method here

}

Hi Jerome, thanks for the prompt reply.

Ahh yes, of course I can see how I might end up in a loop. :-S

I am not sure if I can use onBeforeProductUpdate as ultimately I need to process some information from an uploaded file and if I understand correctly the file will not have been uploaded at this point.

I will outline what I am trying to achieve. Perhaps you could advise the best way for me to do it.

Outline...
- I am using HikaMarket to allow users to sell downloadable files.
- All files (products) are exactly the same type.
- Products have several custom fields. These are not visible to the front end vendor when they create a new product but are displayed in the product listing
- The Custom field data is extracted from source of uploaded file.

So my basic idea is something like this...
- User uploads a product for download.
- Plugin detects onAfterProductUpdate trigger and gets product id from $product -> product_id
- Plugin cross references the database #__hikashop_file table to get the filename
- Plugin passes filename to method to extract data for custom fields
- Plugin updates the custom fields.

I guess ultimately I could update the database direct but It would be good to use a built in method to do this and keep things tidy.

If you have any ideas it would be very much appreciated.

Thanks Jerome,

I had just implemented JFactory DB methods to update the data but being able to use onBeforeProductUpdate now makes the whole thing very much easier.

Just a quick update on this.

As I opted to not display the custom fields in the front end form, what I found was that when the product was updated all of the custom fields were overwritten with NULL / Blank values. Basically the data in the custom fields was deleted.

To get over this I opted to show the fields in the front end form but to hide them with the CSS display:none attribute. This was pretty easy as each custom field has its own CSS class. I just added the relevant definitions to my templates CSS file.

Hope this helps someone out in the future.

Hi Jerome. I am using HS 2.2.1 and HM 1.3.0.

Hi Jerome, I will look at upgrading.

I actually wasn't aware that there was a more current version. Guess I should pay more attention

The settings are below, the only difference is that now I have the setting Display-> Front End set to yes instead of no.

Jerome,

A bit off topic but just to let you know. My installation is showing as up to date even though version 2.2.1 is installed.

The Admin dashboard says 'All extensions are up-to-date'
The Hikashop > documentation > update / about says 'You have the latest stable version of HikaShop Business: 2.2.1'

I am using Joomla! 3.1.5

Seems to be an issue with the auto updater

See, told you I should pay more attention
