block_example_help

Implementation of hook_help().

Throughout Drupal, hook_help() is used to display help text at the top of pages. Some other parts of Drupal pages get explanatory text from these hooks as well. We use it here to provide a description of the module on the module administration page.

developer/examples/block_example.module, line 17

This is an example outlining how a module can be define blocks to be displayed on each page.

Code

function block_example_help($section) {
  switch ($section) {
    case 'admin/modules#description':
      // This description is shown in the listing at admin/modules.
      return t('An example module showing how to define a block.');
  }
}
