Drupal 8 Developer Prep Chapter: So with our two files and our info dot yml file filled in, we should be able to see our module show up on the module listings page. So jump back to the browser and we are going to expand the Menu by clicking the Menu item at the top, and then we'll move the Menu off to the side just to give us a better perspective on the page that we're viewing. So we're clicking the side menu icon here which moves it over here, and let's click on Extend.
In this article, I would love to draw your attention to Drupal 7 performance only. I'd like to highlight these options.
Website performance is very important because it can lead to higher conversion rates, higher search ranking and hosting costs reduction. In this article, we'll look at the different ways and remember how Drupal 7 performance can be improved. Some improvements are easier to implement than others though.
Let's start with the easiest settings to set. People complain sometimes that Drupal is slow, but I saw many sites hadn't had JS or CSS aggregation enabled which is just 2 checkboxes in the settings which noticeably decreases a number of files to load: Software When it comes to back-end tips, you'd better use relevant software releases.
Drupal 7 officially supports PHP 5. Popular contrib modules also work with PHP 7 very well and there is a very low probability that the contrib project you want to utilize doesn't support Drupal hook content save 7, and maybe you'll need to adapt custom code.
We agreed that the recent software is a must. The same applies to the latest Drupal updates. Drupal core and modules New Drupal and contrib project releases can contain not only bug fixes, new features and security fixes please update as soon as possible in this casebut also performance improvements, so you should use the latest available versions and update regularly.
And it's very natural that they have different settings and lists of enabled and disabled modules. In the production environment, you definitely should not have development-helper modules enabled, but there'll be some other, for example, Google Analytics, which you'll probably have enabled on the production only.
So, don't forget to disable the modules that you don't use to avoid loading needless code which takes an additional time. Drupal core caching Drupal core provides options to cache blocks which should be enabled if possible and also to cache whole pages for anonymous users which are very useful for content sites on which the most of regular users are anonymous.
Drupal is used with many contrib modules, and it's important for them to utilize caching and provide their own caching, related configuration possibilities and related configuration. In case of the complex output with a lot of fields, it may be heavy as well.
Views provide a time-based with a specified cache lifetime cache and both the raw query result and a resulting output can be cached. This results in better cache utilization in comparison with a time-based caching. In case updates on the site happen not frequently for example, blog with a few new posts per week cache may live for days and even weeks and reflect content updates immediately in comparison with the time-based cache where lifetime is usually limited to a few hours at the maximum.
Varnish A pages cache for anonymous users provided by the Drupal core requires a partial bootstrap to deliver the cache from Drupal.
DiscoverDesign and the Chicago Architecture Foundation: Using AngularJS and Drupal 8's REST API for Content Management by Benjamin Doherty • October 28, This post is the second in a series describing Caxy’s work architecting the DiscoverDesign site in Drupal . The Codex has a list of the typical actions run during a page request, but it’s based on WordPress and using the Twenty-Eleven alphabetnyc.comg that some content in the Codex can be outdated, I wanted to have this list of actions as up to date as possible. If you are starting to learn Drupal 8, you are probably overwhelmed by the number of blog posts that offer free tutorials on different aspects of Drupal 8. The only way to find all these tutorials is to search online. In this post, we have created an exhaustive list of the free resources online for mastering Drupal 8, organized by categories.
In advanced usage, Varnish can be utilized to cache content for logged-in users as well. Varnish integration with Drupal may differ depending on hosting actually. For example, on Acquia you will not need the Varnish module, it just will not work. Note configuration code example: Please check your hosting documentation first to configure Varnish properly.
Boost When Varnish is not available, there is one more simple option to cache whole pages for anonymous users for better performance: In Drupal core nodes, comments, users, taxonomy terms, taxonomy vocabularies, and files are the entities.
Many other types of entities are defined by contrib modules, and the entities defined by custom code are very useful as well. Fieldable entities, especially when there are many fields attached, may be too heavy to load them fast. When entities are frequently loaded on a website, for example, because of some processing as a reaction to some users' actions, it's better to cache the entities.
But it's highly recommended to use it with Memcached or Redis as a cache storage to achieve the maximum performance improvements. Search Drupal provides search functionality from its core and stores a search index in a database, and maybe not performant enough when there is a lot of content on a website.
It also adds some new features to Drupal search functionality.
You should never implement full-text search functionality by building the output via the Views module and querying results from the database using "contains" conditions.
Basically, there is no need to execute all of these tasks at the same time which is the default behaviorespecially when you need to execute some of the tasks very frequently, for example, a scheduled content publication, subscriptions' expiration or queue processing.
In such cases, cron tasks running simultaneously may cause performance issues and a frequent execution of tasks which shouldn't be done that often: For example, you may want to cache some meta information received from a third party service.
Conclusion As I mentioned at the beginning of the article, website performance is very important. This article covers several ways to improve Drupal performance on the server side, but it's not a complete list, of course:So you have made a custom form and you have not altered the existing form (my assumption as if you would have altered any existing form then won’t be any need for you to ask this question) You have to save the form yourself, drupal is not going to.
Any ideas if this can be done? I want to restrict the number of items returned to 5. Not sure if I can do this somehow at the CQWP or list level? In the example screen shot above, we have various local task menu tabs when viewing a node as an admin user.
The 'View', 'Edit' and 'Revisions' tabs are provided by Drupal Core, the 'Group' and 'Menus' tabs are provided by the Organic Groups module and the 'Devel' tab is . Addressing the issue of not finding the attributes set in your page load.
I am not entirely clear on what you are trying to accomplish, but it seems likely that you are . I have a custom date field in a node type 'day'. When the node is saved (or edited then saved), I would like to get the field_date value (not the published date) and save it into the title field.
