Solved: [API] $modx object inaccessible from a function in a snippet

Hi,

I’m writting a snippet and observed that the "$modx" object cannot be accessed from within a function inside my snippet. I’m surprised that it is not global.

is ok in the snippet core.

When put inside a function in the snippet I get :

Fatal error: Call to a member function getDocumentObject() on a non-object

Any idea how to handle this ?

Should I do something like :

and in function

or pass the $modx object as parameter of the function ?
I assume that the $modx object is quite large. Isn’t it ?

Thanks for your help.

Seem that the solution is adding this in the function :

An example is available here with the getParents() function in the snippet:

If you refer to a variable inside a PHP function, PHP assumes that you want a local variable whose scope is that function, *unless* you declare it as global at the top of the function, in which case, PHP knows that you mean to refer to the global variable defined outside the function.

@Bob: Thanks for this interesting explanation.
I had not tried it by fear to overwrite the modx object as it would happen with other programming languages, until I saw an example.

Glad you got it working. PHP does take some adjustment for those of use arriving from other languages (C++ in my case).
