1. DRUPAL DEBUGGING TIPS
==== DRUPAL DEBUGGING ====
1. Access all available variables in page.tpl.php using devel module
<?php dpm(get_defined_vars()); ?>
2. Inspect function calls
<?php dpm(debug_backtrace()); ?>
or just use
<?php ddebug_backtrace(); ?>
3.) Use the debug() just like dpm() or dsm() in devel
$label, $print_r);
