When debugging Drupal, I often stick dpm($some_array, "my array");
calls to see what the value of $some_array
is.
This fails spectacularly if the code I'm debugging is run very late in the request after drupal_get_messages()
has already been called. (Eg most hook_preprocess_THEMEHOOK
functions).
In that case, I've found it useful to add these helper functions somewhere (any enabled custom module, or even index.php
), use them instead of dpm
. They'll serialize objects to apache's error_log (wherever that is), which you can track by opening a terminal tab and running:
tail -f /var/log/apache2/error.log | tr '%' "\n"
