Hi Pablo,

I’d have to look into it… but for the sake of giving you a quick reply, if you click on the devel tab I would think the arrays would become available as variables for the page, in which case you could view them using dpm( get_defined_vars() ); as above.

great article one question though is there anyway you can call the arrays that are generated from the dev renderer tab

I too found this “informative and handy”. I’m new to drupal and web development and little tips like this help a lot. Thanks.

Hi Neil Satra,

Thank you for pointing out the Dev Load and Dev Render tabs for those that may not have been aware that they existed. However, I would give you the same advice. If you took 5 minutes to read my article you would have discovered that I say dpm() is part of the Devel module in the first paragraph. Also, using the Devel tabs as you suggested only gives access to the properties of the $node object, whereas dpm( get_defined_vars() ); returns all variables available to a particular Drupal page. Additionally, Dev Load and Dev Render do not provide page backtrace information.

Perhaps you could contribute to the community knowledge base and write a post on Dev Load and Dev Render and post a link to it in the comments here?

hey….just a friendly tip. next time, put in 5 minutes of research before writing articles like this. the function you have called, dpm(), is not built-in to drupal, it comes with a module called devel. and if you have that module installed, you don’t really have to do all this manually, you can just check out the dev_load and dev_render tabs on each page….

i put in the code without having drupal installed, and was wondering why the function was termed as undefined…
