How to add an extra field to a category more correctly?

I need an additional field to the category so that I can implement the function:

Related categories (@)...
https://forum.flynax.com/showthread....categories-(-)

I can do this without any problems by adding it directly to the base and changing the system files and template files.


However, how correct is this approach?

Maybe I should write a plugin that does this? I will not have to change the system kernel and there will be no problems with subsequent updates.

Hello,

Do you mean an additional field on the category add/edit form?

so you need to modify two files:

categories.inc.php from admin > controllers

and categories.tpl - admin > tpl > controllers

> Do you mean an additional field on the category add/edit form?

Yes

Perhaps it is better to do this with plugins (rlHook) using hooks so as not to change the system kernel? After all, if there is a plugin, subsequent updates will be easier to do. In order not to lose your work with the update.

You can add your hook via mysql request without using classes

for category add/edit form you need to use a hook name apTplCategoriesForm like:

PHP Code:

---

Only registered members can view the code. 


---

Where --PHP CODE-- - your php code

or you can directly attach your custom tpl file from templates > your_template with smarty code inside using:

PHP Code:

---

Only registered members can view the code.

All is decided. Thank you very much.
