Can't see the "help" hook on the Modules admin panel

Question

I'm reading Drupal 7 Module Development and trying to learn module development. I've created their example module 'first' and I'm not seeing the 'help' link.

Here is what I have so far...

/sites/all/modules/first/first.info

name = First
description = A first module.
package = Drupal 7 Development
core = 7.x

/sites/all/modules/first/first.module

<?php

/**
 * @file
 * A module exemplifying Drupal coding practices and APIs.
 *
 * This module provides a block that lists all of the
 * installed modules. It illustrates coding standards,
 * practices, and API use for Drupal 7.
 */

/**
 * Implements hook_help().
 */

function first_help($path, $arg) {
  if ($path == 'admin/help#first.') {
    return t('A demonstration module.');
  }
}

Now then... according to this book, when I install/activate the first module, I should see a () Help link to the right of my module name in the Modules admin panel.

I don't. What could be stopping this link from populating this screen. I get () Help links for all of the other modules. But not mine.

I created a subdomain on my server and installed Drupal to test with a fresh Drupal install. The help link shows up and works on the new install. So now I'm trying to wrap my head around what could be killing it on my other Drupal site? Could Devel? Coder? This is very weird.

Answer 1

You have a period at the end of your path condition.

Try this:

function first_help($path, $arg) {
  if ($path == 'admin/help#first') {
    return t('A demonstration module.');
  }
}

Answer 2

A note about modules with more than one-word name: the path must match your module name, if the module was called "first_module" the path "first-module" would not work (underscore vs dash). It should look like this:

function first_help($path, $arg) {
  if ($path == 'admin/help#first_module') {
    return t('A demonstration module.');
  }
}

Hope this will help you!!

• First of all disable the module and enable it again. Also go to Administer > Performance and hit the "Clear cached" button.
  Hope this will resolve your issue.

  If the issues is still there then,

• If you are using Drupal 7, this link will help you. You can see different examples.

• After enabling the module clear cache.

Answer 4

For anybody else who's having this problem, make sure that the Help module is enabled. That fixed it for me.

Answer 5

Enable the Help Module from admin/modules, then refresh page again.
