Drupal hook_user

Same "object", different behavior based on data Naked object Use: Horizontal object extension pattern See: State pattern. Any hook is a passive observer pattern. You'd have to register. This one is weird. Couldn't fit OO syntax for this on a single slide. You want an object to talk to you in a certain way.

Hooks allow modules to alter and extend the behavior of Drupal core, or another module. They are one of the various ways that code components in Drupal can communicate with one another.

Using hooks a module developer can change how core or another module works -- without changing the existing code. As a Drupal developer, understanding how to implement and invoke hooks is essential. Understand what hooks are and how they are used in Drupal.

Be able to know where to find information about implementing and invoking hooks from your custom code. From an implementation perspective hooks are specially-named functions called at specific times to alter or add to the base behavior.

Each hook has a unique name e. Every hook has three parts; a name , an implementation , and a definition. The implementation consists of the custom code in your module that you want to execute. Another module or subsystem provides the definition, which specifies the hook's name and which arguments are passed to the implementation, as well as when the implementation will be called.

Any number of modules can implement the same hook. This allows multiple modules to contribute to the final outcome. Each implementation function will be called in order based on the module's weight stored in the core. If multiple modules have the same weight they will be called in alphabetical order based on the module's machine name.

Note: drush cget is shorthand alias for both the Drush 8 command drush config-get and the Drush 9 command drush config:get. At their most basic, hooks are a naming convention. Define a PHP function whose name follows a known pattern, and Drupal will call that function at critical points during the life cycle of a request.

Just replace the word HOOK in the hook definition with the machine name of your module, and presto, you've implemented a hook. Hooks that answer questions , often referred to as "info hooks", are invoked when some component in Drupal is gathering a list of information about a particular topic.

For example, a list of all the items that should be displayed in the toolbar, or a of requirements to verify prior to installation.

These hooks primarily return arrays whose structure and values are determined by the hook definition. Note: Drupal now has fewer info hooks than Drupal 7. Info hooks used to be the primary way of gathering new lists of functionality. Now, the plugin system generally handles this. These are often paired with info hooks. A component may first invoke an info hook to gather a list of information, then immediately invoke an alter hook to allow anyone to alter the list that was just created before it's used.

You might, for example, change the order that items are listed in the Toolbar, or even change the name used for an item added by another module. Hooks that react to an action , similar to events , are invoked when specific actions are taken in code somewhere in the system in order to allow other code to do something based on that action.

Modules that store data about users that need to perform cleanup tasks can implement this hook to be notified about the account that is being canceled and take the necessary actions on their own data. In this tutorial, we learned that hooks are composed of three parts: a name, an implementation, and a definition. We learned about the naming convention for hooks as well as three kinds of tasks you can perform with a hook: discover existing hooks, implement a hook, and define invoke a new hook.

Finally, we learned about the types of hooks: hooks that answer a question, alter existing data, or react to an action. Skip to main content. What Are Hooks?

I can barely remember the first time I added JavaScript to a Drupal page using a custom module. I'm sure looked at the documentation, took the example snippet, tweaked it, tested it, and moved on to something else.

I have a Drupal 6 website which is hosted on a shared hosting service and which is used to communicate with a desktop software application. Over the years I extended the user profile with over 70 different profile fields. With over Switching host or upgrading Drupal 6 to Drupal 7 is not an option! Since the profile data is only used when the software communicates with the website, which is done once per application start I did not really have a need for such a large profile table so I created a custom module which stores the profile data per user in a single row as a serialized array. This also has the benefit that I don't need to update my website every time a new profile value is added in the software.
