Drupal 7 hook preprocess block

When drupal wishes to allow intervention from modules, it determines which modules implement a hook and calls that hook in all enabled modules that implement it the available hooks to form for a block hook_block_info, define all blocks provided by the module hook_search_preprocess, preprocess text for search. Preprocess is a very common function in drupal to alter the content and other properties like lable of a block the drupalorg url itself also provides a glimpse of what it looks like to preprocess so here are the ways to preprocess blocks within your theme drupal 8. From adding a custom code field, blocks, to dynamic fields, each of these can be moved around your layout and replicated/modified display suite for drupal 7.

Overview creating custom blocks in drupal 7 seems like a pretty straightforward process in drupal 7 you first implement hook_block_info() to tell drupal about your block, then you implement hook_block_view() to set the contents of the block for the user the api pages on these functions explain how to do this, and. The standard more link the views module adds to it's blocks has no place on a modern accessible website, you really need a more verbose link in there below, the above is drupal 5x only - the principle could be applied in 6x using a preprocess hook (either in your templatephp or in a simple module. But if you're determined, then even drupal 7 provides you with a number of core and contributed mechanisms for factoring code over multiple files for beginners when you declare a new theme hook, your module's templates can go in one folder, and preprocess hooks can go in one or many other files.

Understanding how to use preprocessor in drupal can be very confusing in this post we will explore how to achieve adding a variable to a node template file using the preprocessor hook (function) the first thing we need to create is the preprocessor function that has mandatory elements so that drupal can see the hook. There can be none or many template files for a theme, including (but not exclusively) pagetplphp, blocktplphp, nodetplphp what can you to print out a list of available hooks on a given page, we create the simplest preprocess function (using the dpm() function requires the devel module): function.

//main menu (top) using the menu block module function mytheme_menu_tree __menu_block__2(&$variables) { return '' $variables['tree'] '' } //main menu (level 2 sidebar) using the menu block module function mytheme_menu_tree__menu_block__1(&$variables). The conventional way of adding a new region to your theme in drupal 7 is by editing the info file and declaring it in there however, there are this drupal hook takes three arguments( &$info, $file, $type ) and alters the data transmitted to drupal from both theme and module info files so in order to make. If you use a preprocess function, the variables will be available in the template of the block i think that whole site have in mind that it's not a good drupal practice another alternative is to add variables in the site information variables table using the hook hook_form_form_id_alter as follows: function.

My work around until #939462: specific preprocess functions for theme hook suggestions are not invoked is fixed: implement preprocess_links and check for language switcher links my example for setting the iso language code in the language switcher block / implements hook_preprocess_hook() / function. $classes: string of classes that can be used to style contextually through css it can be manipulated through the variable $classes_array from preprocess functions the default values can be one or more of the following: block: the current template type, ie, theming hook block-[module]: the module generating the block.

For example, on the mcgill university health centre website, we decided to replace the standard read more link on several block views with a link to a filtered there's a useful thread on drupalorg about the relationship between views templates and preprocess functions:.
