How to create a basic block code in the new Drupal 7 ...

Hi everyone!

As many will know, Drupal 7 comes with important changes, including the hooks. In the previous version of this powerful CMS to create a block from a custom module we had to use hook_block(), this function has been deprecated, and now is separated into eight different hooks:

 

In this post we will programming a basic block, so we only use hook_block_view() and hook_block_info() and the rest we can leave for another day...

Explaining a bit how it works...

In D6 we had to use a switch inside hook_block to know when it was making a request of type "info" and when one of a kind "view". In D7 we have a hook for each of these requests so that our code can be more clear and legible.

 

We see the example

example.info

{syntaxhighlighter brush: php} ; $Id: example.info,v 1.0.0.0 2011/02/09 10:11:15 MyName Exp $ name = "Example Block" description = "Example Block In Code" core = "7.x" package = "Custom Modules" {/syntaxhighlighter}

example.module

{syntaxhighlighter brush: php} // $Id: example.module Exp $ /** * Implementation of hook_block_info(). */ function example_block_info() { $blocks['my-block-id'] = array( 'info' => t('Block Name'), ); return $blocks; } /** * Implementation of hook_block_view(). */ function example_block_view($delta='') { $block = array(); switch ($delta) { case 'my-block-id': $block['subject'] = t('Block Name'); $block['content'] = example_contents(); break; } return $block; } /** * custom html block * @return string */ function example_contents() { return '

Hello World, this is a example custom Block

'; } {/syntaxhighlighter}

 

As you can see is very easy to apply and more understandable than before...

Until next post!
