[SOLVED] List of hooks for admin category edit page? Prestashop 1.7.6

[direwald]

Since in 1.7.6 category and category edit page was one of the pages migrated to Symfony I can no longer add custom fields the way I used to in 1.6 without touching the core files (at least not to my knowledge). So I figured I'll budge and use modules and hooks, but I can't find any info on which hooks are actually used on the category edit page. The documentation doesn't mention any and debug only shows the default ones that show everywhere.

Compare that with hooks on product page where we have like 10 hooks to work with and this seems a bit off. Which leads me to the question, did anyone have any luck with finding what, if any, hooks are called on the category edit page that we can use to add our own custom fields etc.?

Hi, thanks for the links, that looks promising. I'll try digging deeper into that and hopefully figure something out.

So I did manage to locate the hooks and add my own custom field. In case someone else is having the same issue, here's my module file that creates a new field on admin category page. The field itself doesn't save or do anything yet, as I haven't gotten around to it yet, but you can use this as a framework I guess.

The hooks that you can use to modify the category page are: 

actionCategoryFormBuilderModifier
actionAfterCreateCategoryFormHandler
actionAfterUpdateCategoryFormHandler
