How to display data from database in drupal 8

Some optional properties are URLs, Bundles, and labels. They can be viewed, loaded, created, saved, and deleted, as well as have access permissions set for them. Most things in Drupal are entities, such as Users, Nodes, or Blocks. Many of the core services provide functionality for interacting with entities, and a great deal of caching functionality serves to make entities perform better. Most entities exposed to the user will also be fieldable, which means any amount of fields can be attached, transversed, and modified either by code or in the admin GUI. While all entities in Drupal inherit basic functionality from the core entity class, they tend to fall into two different categories: configuration entities and content entities.

A better search for Drupal

Setting up a robust Drupal internal site search that searches all of the content that you add to a complex site can be a bit like finding your way through a maze. Drupal 8 core Search has been revamped and is much more powerful and accurate than in D7, but it still concentrates on text in nodes and not other entities those nodes might contain—like Paragraphs, Views, or custom blocks.

Core Search also does not allow you to choose which fields you want to index, how important those fields are, or use any preprocessors to tailor your search. Search API gives you all this and more. Search API is a Drupal contributed module that allows you create searches on any entity known to Drupal.

You can use Views to create a custom search results page with specific filters. You can create different indexes tied to specific sections or content on your site. You can do just about anything to architect your search experience other than use the core Search block—which is really the only thing that makes core Search worth using. This post however, will show you how to take advantage of the power of Search API, and keep your site search box.

It will meet all your needs for a small site. Be okay with that. Search API is a large and powerful animal. Thankfully, there is a lot of documentation to help you. Unfortunately, there is a lot of documentation to wade through. On a recent D8 site, we had core Search enabled because we wanted to have a global search block in the header—like most modern websites. After much googling and wading through the Search API documentation—which we had not gone through before enabling and configuring the module—we learned that having both core Search and Search API enabled not only is drag on site performance, but can lead to inaccurate results.

In our case Search API was indexing everything on the site but was interfering with core Search indexing the entire site. Only one suite of Search modules should be enabled at a time. Pick one search module solution and use only that one. As noted above, for smaller sites and less complex search needs, core Search is completely fine.

If you think you need something with a little more power under the hood, here some of the benefits of Search API:. You can create different indexes for different types of entities for custom searches on specific areas of your site or combine them all into one site-wide search.

You can choose to index nodes, but exclude certain content types. You can index the title and body field, but not your banner image field. You can customize your search indexes to be pretty much anything you need. Besides customizing what Search API will index, you can define how important the items it is indexing are. You can set the title field to be the most important thing to index. This would show nodes with the keyword in their title before those that only have it in the body.

You can use preprocessors in the Search API UI to exclude unpublished entities, ignore text case, define words to be ignored in searches, split text into individual word tokens for searching, add boosts to datasource types and specific HTML tags, check for node content access, highlight results in an excerpt, and stem results to their English root words jumping would be indexed as jump.

Drupal core Search indexes the site only on cron runs. Search API lets you choose to index on cron runs and set the batch size as well, but you can also index new items automatically and index the site anytime you want from the UI—which is handy when migrating content. One of the things we most enjoy about Drupal 8 is the switch to Twig templating. You can use Twig to customize the core Search results pretty much however you want, but we understand that not everyone knows and loves Twig the way we do.

Thankfully, with Search API you can build a custom Views search page, and create your results list and filters based on your needs—all through the UI if that's how you want to do it.

You can also do this from the command line: drush pm-uninstall search. The first thing we need to do to get Search API up and running is to create a search server. Make sure the Backend is set to Database it should be if you have the Database Search submodule enabled.

Configure the Database Backend. We usually set the minimum word length to 3 and do not search on parts of a word. In order for Search API to work, it needs to know what content to look at and catalogue.

This means we need to configure a search index. Unlike Drupal core Search which concentrates on node entities, Search API allows you to choose to include any entity recognizable to Drupal. You can configure one index that will keep track of all entities or you can create different indexes for different entities and use different views to allow specific searches for certain content.

A prime example would be a university with custom searches set up per department. Configure the datasources how you want them. You can choose to include and exclude different types for each datasource entity. Index options allows you to choose to Index items immediately. New nodes and entities will be added to the search index immediately instead of waiting for cron to run. Index options also lets you set the number of entities to index per cron run. We keep the cron batch size to the default of 50 since we are adding new entities when they are created.

You can define fields for each datasource, but not each type within the datasource. We usually go with indexing our main node fields—title, subheader, and body. These are the fields most likely to contain relevant search keywords. You can define the index field type for each field and decide the boost value to give some fields more relevance than others.

We always boost the node title the most and assign the rest of the boost values based on the importance and relevance of the content to the node.

Make sure that every field you have listed here has its type set to Fulltext—no matter what the actual field type or formatter is on your content types. Since we are going to be setting up a custom views search page later and using the Fulltext keyword filter, only fields listed as Fulltext here will be available to that filter.

You can change data before its indexed to create keyword tokens, ignore case, or filter out certain HTML. You can highlight keywords in the search results only works if showing a search excerpt in your search results. You can also bring keywords to their English stem, exclude certain words from being indexed and use transliteration for non-English text. We like to use Entity status to index only published entities, HTML filter to strip tags and decode content that might be in the body field, Ignore case to give the broadest results, Tokenizer so that test strings can be split into single keywords for searching, and Stemmer to trim keywords to their root.

Thankfully, Search API does a nice job of letting you know which processors work at which times and even lets you know if a certain processor needs be at certain point in the order to get the best results. Most of them offer options to enable the processor on all supported fields, or just on some.

You can define the excerpt and highlighting tag if using Highlight. You can also set the minimum word length for Tokenizer. Our HTML filter boosts tags with h1 as the most important and each subsequent tag as a lesser value.

Tokenizer should be set to the same minimum word length that your Index database configuration is set to—3 for us. Now that we have the search server and index all setup, the site is ready to start indexing nodes. You'll want to click on the View tab for the index, then click the Index Now button at the bottom to index the site. The next thing we need is a way to display search results. We named ours Site Search. Make sure that in the view settings the Show select list is set to Index Content and the box to Create a Page is checked.

The fields you show in each row of your results are specific to the datasource. We usually use just the node title and body field for results, but any field on can be added as long as a field on its parent datasource was indexed.

For instance you can add a banner image field from a node content type to your results because you indexed the node's title field. You can filter by more fields than what you are showing so if you have more indexed fields, you can still get a solid keyword search but only show the results field you want—similar to the Drupal core Search excerpt.

We also recommending linking the title to its node, trimming the body field and stripping out HTML tags using the rewrite option for the body field. The Highlight processor needs an excerpt to work.

Remember when we changed all the fields in our index to Fulltext? Guess what filter we are going to use? This is similar to Views Global Combined filter except that filter reads the view results instead of the search index, so it would not use the query processors outlined in Search API nor the indexed field data. Using a Global Combined filter would return an error instead of search results. You can set the Fulltext search to work how you want, but we prefer to run it to contain all of the keywords a user puts in and to parse them as a single string.

For searched fields, set the filter to all of the fields you have set in your index. There is no reason to index fields if you are not going to allow a filter for them unless you are doing multiple Fulltext Search filters on different fields—for instance, a keyword filter that looks at title and body fields and categories filter rather than looks at a term reference field.

The minimum word length should be set to the same minimum word length assigned in your index. We recommend sorting your results by relevance. If you do so, make sure you choose descending so you get the results with the highest relevance first.

You can also sort by any of the fields you added if you want to sort results alphabetically by title or something. Most importantly, you want to go to Exposed Form in the Advanced settings section and change Exposed form in block to Yes. This is how you get a search filter block to replace the core Search block we lost when we disabled that module. We also like to set some helpful Text on demand text in case someone gets to the search page before they have searched for anything.

Your view must be set to be a view of Index Content in order for it to read the index you just created. Each field you want to show in results must be an indexed field and if you are using the Fulltext search filter, all of your fields in your index must be set to Fulltext.

Once you choose your filter block, you can configure it like you would any block. For more information on creating custom twig template, see our Twig for Drupal 8 Development: Twig Templating Part 1 of 2 post. Normally, you cannot get exposed filters on a view page when you have assigned those exposed filters to be in a block. However, we have come up with both a developer and non-developer way to do so.

Feel free to use either based on your comfort level with Twig and custom templates.

The Views module has been a cornerstone of Drupal ever since it was introduced in A Mysql view allows you create a relationship map between core Drupal database tables and a table or tables in an external database. This means that you can define a relationship to content from a completely different application without the need for a service layer, provided you have read access to the other database. Imagine you have an install of Drupal and an install of another application on the same web server. The next thing you need to determine is how those records correlate to one another. If this all worked out you should see output similar to this.

If you wanted to display data from your DW using Drupal, the Views module is a good place to start. Before you can use the Views module you need to connect to the database and describe the tables to Views.

There's also live online events, interactive content, certification prep materials, and more. This section of the book covers special topics in Drupal programming that you can use to enhance websites built with Drupal. My advice would be to skim the sections of this chapter now so you know what is there, and then read them in more detail when you need them. This section of the book goes into more detail about how a module you write can be part of that process, by registering with Drupal to handle specific URLs, by providing page and block content, and by generating and processing HTML forms. 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.
