I am trying debug a custom rule I am creating. In my helper function I am calling an array I want to work with. I want to dpm the contents of the array so that I can see what is available, but it is not working. To check that there wasn't a problem with my array. I set up a new one inside the helper function.

$array = [
      "foo" => "bar",
      "bar" => "foo",
  ];

and then try to dpm the array:

dpm ("array: " . $array);

but all that is shown in the status message is:

array: Array

I have been trying other methods of printing the array like print_r but haven't had any success with these either. How should I be printing my array?

You can only have a string (not an array) as the second argument to dpm().

Try:

dpm($array, "array: ");

  • Thanks. I had been banging my head against the wall over that! – Paul Trotter Apr 11 '16 at 13:02
  • I would advise using xdebug to debug this sort of thing - it will really save you the headache of trying to debug custom rules. – Kevin Apr 11 '16 at 14:53
