Need help with Module for changing Add Category and Update Category page

[slymatt]

Hello,

 

So my issue is im trying to create a module that attaches to the hooks:

 

actionCategoryAdd

actionCategoryUpdate

 

But when i use 

public function hookActionCategoryAdd($params)
{
   return $this->display(__FILE__, 'views/templates/hook/newfieldstut.tpl');
	
}   

Nothing shows up am i doing something wrong?

 

Cheers in advance

Well first what you are trying to accomplish with module ?

 

Second those hooks have action in their names so they used when you want to change some 

data on category add or update. They do not display anything. You need to use display hooks 

if you want some code from  tpl file to appear.

 

Also you consider creating custom hook for your module.

All im trying to do is add a single field that will be added to the database, i need all the code to be held within the module

 

Does this help ? =P

Maybe this tutorial can help  http://nemops.com/extending-prestashop-objects/#.VkYOUPmrTIU

But isn't that overloading instead of adding to?

 

Also i dont see a 

 

displayCategoryAdd

displayCategoryUpdate

Yes it is overriding.

 

If you want to add field to category admin page, you need to override

correct admin tpl file and maybe AdminCategory Controller.

 

Sorry you said all code you want within the module. But module can override 

files on install.

 

But to get to your first post, maybe action hooks are 

good to use in your case just use them to save data not 

displaying form.

[slymatt]

if i override this could cause issues for other modules that may be installed couldnt it, and i cant just use an action hook as you said because i need to display the field first to get the input.

 

I dont want to cause issues with other modules 

[razaro]

Yeah I understand, and it is recommended to not use overrides if possible.

 

Ok let me ask for more info.

 

Where you want to show that input , back office or front office, can you display it in modules page?

Could you maybe create new table that will save input and id of category ?

[slymatt]

Ive added an image where i wanted the new field its in the backend Where you add a new category, also update the category aswell.

 

I could add it to the config page and loop through each category but that would be a ton more work that i was hoping wouldn't be needed

 

Hope this clears a few more things up.

Does that make sense? 

[slymatt]

Still cant figure it out =S

[razaro]

Well I do not know other way then override to do that.
