Please use the Relations instead.


This function is used to automate the links creation and destruction with simplified command.

After saving an item, if the POST query has sent more datas concerning relations with other tables, this function must be called.

This function will insert or delete rows in database.

Awards for the best Joomla app. This product is gonna win an award for this amazing job. Cook Self Service is the the best application from all over the Joomla universe ! It brings Joomla to a professional level really advanced for developers. It is a real fun to develop with it. The ACL part and security checks implementation are just... so much hours saved. I can now concentrate myself more on the design part and the creative works. Thank you so much. Guys I offer you all my congratulation ! Keep up the works because Joomla is needing it to increase the quality of extensions availables on the JED. I also learned a lot because I can see how to code at the proper place and I found all my answers reading the forum.
