Users Export module hook

Question

I'm using Users Export that provides a hook with no extra information.
I need somehow to explore the $info parameters in order to this extra fields

my code:

function display_my_users_loft_data_grids_info_alter(&$info) {
    var_dump($info);
}

But in that case the var_dump doesn't work.

Does someone know any example or documentation or help me to debug that?

Answer 1

Get the Devel module installed and use the dpm() function, e.g.

function display_my_users_loft_data_grids_info_alter(&$info) {
    dpm($info);
}

Then perform whatever action it would take to invoke that hook, and you'll see the $info variable exported to the messages area for easy browsing.
