![]() After saving permissions, go to the main page. Simply do not grant any permissions to any role other than the Admin role.Ĥ. It is essential on all sites, including production sites. A common misconception is that Devel should not be installed on production sites because it uses too many resources. Head over to Administer > User management > Permissions, and grant all permissions to the Admin role, and none to any other role, in the Devel module and devel_node_access module sections. Click on the ''Save configuration'' button.ģ. Download and install the module as usual, then enable all the Devel family, the Devel, Devel generate, Devel node access, Macro, Nodequeue generate, and Theme Developer modules.Ģ. And now, starting with Drupal 6, it includes what is billed (justifiably so) as the ''Firebug for Drupal theming,'' the Theme developer.įollow these steps to install and get started with this module:ġ. It had already established its ''Don't leave home without it'' status. It has been popular since its inception, since it makes available a host of helper and utility functions (summary of all database queries for the current page complete with execution times, easy clearing of the cache, reinstallation of modules, access to Drupal variables, a block for running PHP snippets on the fly, etc.). The Devel module ( ), even though it has not made an appearance yet in this book, has been around for quite some time. Just as Earl Miles (merlinofchaos) has made a tremendous contribution with the Panels (you will see this in a later chapter), Views, Nodequeue, and Advanced Help, as well as the Update Status modules, Moshe Weitzman has also, as the author of Organic Groups and a host of other work in the Drupal Community, including the Devel module. ![]() Replace the word template with your theme name or you will end up with a WSOD.Before you commit all your work and call it a day on the upgrade path, it will be well worth the effort to include the all-new Devel module in the mix. ![]() Geofield integrates well with OpenLayers, but in this case I don’t want the overhead of OpenLayers and don’t need to actually display the maps on the node.įirst, create the template_preprocess_field function in the template.php file of your theme. In this example I’m going to take a geofield and change its output to provide a link to a Google Map. When overriding the you’ll end up with a new file for every field you override (something like ). So it could take a large amount of code to build a functioning node override.įewer files to manage. When you override the output of the file to adjust a single field output you are also taking on the responsibility of outputting every field in the specific manner you want. Processing an efficient php function will always be faster than Drupal’s template override system, looking for the right file and processing it. There are a number of reasons why you would want to use this function as apposed to overriding or in your theme: The function template_preprocess_field can be used to manipulate just the markup of the field in the $variables array before it’s output to your theme. Sometimes it would be great to just override the field itself without touching the field values in the database. Overriding the output of an individual field on a node can be done by overriding the node template, but it sure does feel like overkill for just one field.
