Hello everyone,
I want to override fn_clone_poduct function in fn.catalog.php file. My purpose is to set cloned product price to zero. I don't want the product price copied to the cloned product price.
In 'fn_clone_product' function when I comment out the lines for clone price section, everything is right and price value will be set to 0 after it is cloned!
I've decided to create addon to override this function. Here are the steps I've done:
1- In my_addon 'init.php' file I registered 'clone_product_post' hooks.
2- In my_addon 'func.php' I copied 'fn_clone_product' function (with all it's content) and changed the name to 'fn_my_addon_clone_product_post'.
3- In 'fn_my_addon_clone_product_post' I commented clone price codes.
4- In products.php controller (located in app/controllers/backend) I changed the line '$pdata = fn_clone_product($pid);' to
'$pdata = fn_my_addon_clone_product_post($pid);' in clone mode section.
5- Installed my_addon.
But In backend when I click on Clone button a blank page is appeared!
It's my second addon so I don't know if I've created it right! I think my registered hooks name is the problem! In 'fn_clone_product' function there are three hooks which are set:
- clone_product_pre
- clone_product
and clone_product_post
Which hook name should I use for the addon?
Thanks
