In some cases, we might want to modify the form submission behaviour to better fit a particular use case. For instance, we would like to offer our own submit handler, and we will contact the original submit handler under specific circumstances.

Here, we'll utilise the module name example to change the way a form submits when its form ID is demo_form, which is provided by demo module. To do this, we'll create the code that follows in example.module file:

Many of use has faced challenges while upgrading Drupal core from 9 to 10 where some of the modules are not compatible with D10, we might have followed the forked issue approach solution which I have described in one of my previous posts (How to use the Drupal 9 module in a Drupal 10 project using Composer if its MR is already ready...).

We have often found that in the Drupal 9 project, multiple modules are not compatible with Drupal 10, and when we check the module issue queue, especially with the term "Automated Drupal 10 compatibility fixes", we can find at least one issue where the project update bot creates this issue automatically against each module and provides a patch with possible fixes except for making changes in module.info.yml.

Sometimes we need to create a pager for custom data sets, such as retrieving specific types of nodes and applying a filter on top of it to get the expected data set.

In this post, I am going to create a custom Drupal module named pager_example, which will create a pager for a custom data set.

Register a path where we will display a page with a pager using a custom data set. For that, I am going to create a routing file with the name "pager_example.routing.yml", which will have the following snippet:

With reference to my previous post, Setup development environment for Drupal on Windows 10, I noticed that installing drush on WSL using composer does not work by default. In this post I am going to demonstrate how to install drush globally using composer on WSL.

I am assuming you have composer installed. In order to install Drush, we have to follow the below mentioned steps.

Being a Drupal developer, I would prefer to work on a Mac or Linux (Ubuntu) operating system for fast and hassle-free development work, but sometimes you will not get such preferences, may be due to organizations’ norms.

Assume you have a Windows machine for local development and have been assigned to a Drupal project, and you have now configured your local machine for the Drupal project.

In this post, I'll walk you through the steps for setting up a local development environment for Drupal.

Let's assume there is a requirement where we need to filter node content for a given year. We can achieve this by creating a views exposed filter that will filter node content for the selected year.

In this post, I am using the module named "custom_views_filter" for demonstration purposes.

We will create a custom_views_filter.module file and add the below code.

Sometimes we do not want users to uninstall a Drupal module directly, but instead want to perform some checks first.

Let's take a scenario where installing a custom module creates node types along with some fields. Later on If a user wishes to uninstall that module (assuming some content has already been created on the site using the node types that are created by this module), then uninstalling that module can cause a serious problem. It should ask the user to delete the content first that has been created on the site using these node types before uninstalling the module.

In this post we are going to learn how to create module and drush commands using Drush, along with a demonstration of the validate and post hook commands.

First, we will create a module using the drush command. Let's run the following drush command and follow the instructions shown in the below picture.
