php

The purpose of the lock file is to record the exact versions of packages that are installed for your application on your environment. The content of the file is managed by composer and is not manually edited.

When the composer.lock file exists the composer install command will install the exact versions on the lock file and basically ignore the composer.json file.

How to make drupal install notice the composer.json again

Well simply you can

Problem:

I need to place a block added by another module on my page. I cannot add it by placing the block on a region. Because there is specific placement on the content region itself

Solution:

Add the block programatically to the page. We can get the block content programatically on a hook_preprocess function and add it to the $variables to print on the twig template

Just follow this document

You might need to restart PHP so you can do this using the following command (command will change according the PHP version you have).

brew services restart php@7.1

PROBLEM: 

I needed to add a NOT IN condition with a nested query for the WHERE condition. The usual method wont work

 

$view->query->where[1]['conditions'][] = array(
            ['field'] => 'groups_group_membership.type'
            ['value'] => array
                (
                    [0] => 'SELECT_QUERY_HERE'
                  
                )

            ['operator'] => IN
        );

SOLUTION :

The way that works

Problem:

Drupal sometimes shows errors as follows 

Message	EntityMetadataWrapperException: Unknown data property field_activity_status.

Problem : Why would developers use self:: and static:: in PHP OO classes

Solution

Well consider the below code

class Foo
{
    protected static $bar = 1234;

    public static function instance()
    {
        echo self::$bar;
        echo "\n";
        echo static::$bar;
    }

}

Foo::instance();

The output will have no difference

 

1234

1234 

But actually there is a difference when using self:: and static::

Problem: I have a field in my schema that needs to have a value but I cannot make the user input the value in the form. I have to insert it when I am saving the object instance in the database. I can assign a value for this field using the user entered data in the form. How can I do this

Example: For examples sake say I have a filed called FullName, which I have to assign using the user inputs FirstName and LastName.

So basically  FullName = FirstName + " " + LastName.

Solution: Use a event listner  provided by the formBuilder object.
