How do i hide buttons on the menu bar?

(1/1)

kripz:
Not at home atm so i dont have the code to look at but i found the code somewhere, it basically went like this:

Buttons hard coded into an array (with hard coded "show" property).
Loop through array and add to $context['menu'].
Figure out and set context['currentaction'].

Basically what i want to do is hide certain buttons based on the current action.

I have custom buttons added and wish to hide them if currentaction == "forum" (for example).

How can i do this since the buttons are generated before the currentaction is set?

Forum version 2.0.2

kripz:
Thought i had the solution:

add showEx to buttons. In the loop where it adds the buttons to the context, check for showEx value and either include or skip it. However it doesnt behave as intended, can anybody see where i went wrong?

ChalkCat:
Change "show" from true to false ;)

Actually it works, caching was enabled.
