Custom field formatter settings

There's also live online events, interactive content, certification prep materials, and more. My advice is to skim this chapter now so you know what it covers and then read individual sections in more detail when you need them. Examples for Developers , which has comprehensive coverage of the Drupal core APIs and how to use them in your own modules.

This section goes into more detail about how a module you write can be part of that process, by registering with Drupal to handle specific URLs and by providing page and block content.

Given that Drupal has many hooks and that it is written in PHP, there are many ways that you could consider writing code for Drupal that would return output in response to a URL request, or that would place content in a region on a page or set of pages.

Use the methods in this section of the book for best results. Assuming that you have decided you need your module to output some content, the first choice you need to make is whether to provide a router entry or a block. In either case, you will need to register with Drupal for the block or URL, and then write a function or class to generate the output; in the case of a router entry, you will also need to define permissions for accessing the URL. All of these steps are described in the following sections.

Note that you should write code to provide blocks and router entries only if there is some logic or programming needed to generate the content of the block or page.

Also, keep in mind that using the Views module is a better choice than making a custom module in many cases. To define your router entry, first you will need to choose a URL. Here are some considerations when choosing a URL path for your page:. If you are providing an administrative page, the path should be chosen to place the page in an appropriate, existing section of the Drupal core administration screens. Make sure your path does not conflict with a path that another module might provide.

Make your path like others in Drupal. The path can contain placeholders. The menu and routing systems translate the strings when necessary on output. Drupal will verify and run this access check for you automatically and return a access denied response for unauthorized users.

The Page example in Examples for Developers. A related task that you may need to do in a Drupal 7 module is to alter how another module has registered for a URL. One common reason would be that you want to use a different access permission system for the URL. For example:. These steps are covered in this section. To register the URL, create a file called mymodule. As in Drupal 7, first you will need to choose a URL. The first line is a route identifier , which must be unique.

It can also contain placeholders. The defaults section tells what method on what class should be used to generate the content for the path and provides other defaults. You have a few choices for specifying the content generator, which is known as the route controller.

You can also provide default argument values for your page-generating method, by adding lines to this section. The requirements section defines the permission needed to access the page. It must be registered in your mymodule. After registering the route in the routing file, you need to define a page-controller class to provide the actual page output.

For instance, you could make the route defined in the previous section appear in the Structure menu section with this entry in mymodule. In Drupal 8, the creation of a local task to be displayed on a given page is accomplished by creating a mymodule. Besides local tasks, there are also local actions. Local tasks are usually rendered as tabs at the tops of pages, while local actions are usually rendered as buttons. In Drupal 8, local actions are defined in the mymodule. The final type of administration link that you can define is a contextual link, which gives users context-based operations.

They are a little bit more complex to implement than local tasks and actions, because they operate on some specific piece of data and have to be collected and added to administrative pages that display that type of data.

In Drupal 8, the entity system sets up contextual links automatically for content entities; if you want to have contextual links for non-entity data, here are the steps that Drupal core uses to provide this same contextual link. First, choose a group name for your contextual links, which needs to be unique and should describe what type of data the links operate on. In our Block module example, there is a group called block for contextual links that operate on blocks.

Second, in your mymodule. In the Block example, the Configure link is defined in its block. Here, the first line defines the machine name of the contextual link, and the other lines give the group machine name, the link title, and the route name for making the link.

This tells the Contextual Links module if installed to collect all the contextual links in the block group and render them, passing in the route parameter from the current block to construct each link. If the Contextual Links module is not installed, this part of the render array will be ignored. If you want to alter the menu links, local tasks, contextual links, or local actions defined by another module, you can do that with an alter hook. Further reading and reference:. Dynamic routes are for URL paths that cannot be set up as static routes in a routing.

For example, the core Field UI module provides field management pages Manage Fields, Manage Display, and Manage Form Display for each entity type and subtype that supports fields and administrative management.

Because the Field UI module does not know what entity types will be available on a given Drupal site, and because each entity type has full flexibility and control over its administrative URL path, there is no way for the Field UI module to set these up as static routes in a YAML file.

Instead, at runtime, it needs to set up the needed routes for defined entity types. Route altering is when a module changes some aspect of a route that another module has set up. As an example, if the core Editor module is enabled, it changes the names and descriptions of the Filters administrative page, because editors are managed on the same page.

Create an event subscriber class. In your class, override the alterRoutes method, which operates on the route collection the list of all of the routes that are set up by all modules.

Here are some examples:. Because this example is altering routes from the User module, declare a dependency on this module in the mymodule. Put these lines into the mymodule. After adding a new route subscriber, or after updating what it does, you will need to clear the Drupal cache so that Drupal will rebuild its cached routing information.

If you want to provide content that can be displayed on multiple pages, you should register for a block rather than for a path in your module. Blocks can also have configuration settings. The Block example in Examples for Developers and many Drupal core blocks include configuration options, cache settings, and other options.

In Drupal 8 as in Drupal 7 , if you want to provide content that can be displayed on multiple pages, you should register for a block rather than for a route in your module. Drupal 8 uses a plugin system for blocks, so all you have to do to register a block in Drupal 8 is properly define a Block plugin class. The Block annotation provides a unique identifier for the block, as well as the name for the block that will appear on the Blocks administration page.

The build method does the work of providing output for the block. You can also implement or override additional methods to provide access control, caching control, and configuration settings. After defining a new block plugin class, you will need to clear the Drupal cache to make it visible on the Blocks page.

Once your module has registered for a URL or block see previous sections , you need to write a function or a method that returns the page or block output. In many content management systems, and in Drupal 6 and prior versions, output is generated directly and returned as a string of HTML markup and text.

The problem with this philosophy is that when a module rather than the theme is making HTML markup decisions, it is difficult for the theme to have full control over how data is presented. Accordingly, Drupal 7 and 8 use a different philosophy, where modules that provide output for site visitors should always return the output data and meta-data properties, rather than rendered markup.

This data can then be altered by other modules and finally used by the theme system to render the data into HTML. The structure used to return the output data and properties is known as a render array. Here is the general structure of a render array that you could return from a page- or block-generating function or method:. The outermost array keys are arbitrary: choose sensible identifiers that will remind you of what each piece of your block or page is.

At the next level of arrays, keys starting with ' ' are property keys that are recognized by the Render API. You can also provide properties on the outermost array. A ' theme' property, whose value is the name of a theme hook. If used with the ' type' property, it would override the default theme hook for the render element.

Keys not starting with ' ' , whose array values are themselves render arrays. If the parent array does not have a render element type or theme hook specified, each child array will be independently rendered and the output concatenated. If there is a ' markup' property and ' type' is not set, a render element type of markup will be assumed.

Generic JavaScript code and files can be added to a render array by using the ' attached' property. In Drupal 7, the jQuery library will be attached by default on every page, so you can make use of that when writing your JavaScript.

Here are some Drupal 7 examples:. CSS attachment works the same way, with the 'css' array element. You can also define a library that contains one or more JavaScript and CSS files, and it can depend on other libraries. The general structure and many of the details of render arrays are the same between Drupal 7 and Drupal 8. It is still possible in Drupal 7 to return strings from your page and block content functions instead of render arrays. Using render arrays is preferred, however, because:.

They leave final rendering until late in the page-generation process, so unnecessary rendering can be avoided if a particular section of the page is not actually displayed. As noted in the previous section, both the general concept and nearly all of the details of render arrays are the same in Drupal 7 and 8. Here are some differences:. If your render array is being generated in a class that has a t method, you should call this method in place of the global t function, to internationalize user-interface text.
