Drupal 9 Create Block programmatically and insert it in template file

By Houssem on 21 January 2021 in Drupal

Create the block class file /web/modules/custom/my_module/src/Plugin/Block/HelloBlock.php and add the code below. To insert this block programmatically in a template we can implement a hook_preprocess into .module file of our module

<em>/**
 * Implements hook_preprocess().
 */
</em>function my_module_preprocess(&amp;$variables, $hook) {
  static $hooks;

  $block_manager = \Drupal::<em>service</em>('plugin.manager.block');
  $block_config = [];
  $block_plugin =   $block_manager->createInstance('<code>hello_block</code>', $block_config);
  $block_build = $block_plugin->build();

  $variables['<code>hello_block</code>_output'] = render($block_build);
}

/**

* Implements hook_preprocess().

function my_module_preprocess(&$variables, $hook) {

static $hooks;

$block_manager = \Drupal::service('plugin.manager.block');

$block_config = [];

$block_plugin = $block_manager->createInstance('<code>hello_block</code>', $block_config);

$block_build = $block_plugin->build();

$variables['<code>hello_block</code>_output'] = render($block_build);

}

Then into our template file we display the variable

{{ block_related_cases_output }}

1	{{ block_related_cases_output }}

don’t forget to execute : vendor/bin/drush cr

Define a default value in configureFormFields

By Houssem on 25 May 2017 in Symfony

To add some some default field value whith SonataAdminBundle you should use the getNewInstance function :

    public function getNewInstance()
    {
        $instance = parent::getNewInstance();
        $container = $this->getConfigurationPool()->getContainer();
        $user = $container->get('security.context')->getToken()->getUser();
        $instance->setUser($user);

        $oNow = new \DateTime('now');
        $instance->setStartDate($oNow);
        $instance->setEndDate($oNow->modify('+1 month'));

        return $instance;
    }

public function getNewInstance()

{

$instance = parent::getNewInstance();

$container = $this->getConfigurationPool()->getContainer();

$user = $container->get('security.context')->getToken()->getUser();

$instance->setUser($user);

$oNow = new \DateTime('now');

$instance->setStartDate($oNow);

$instance->setEndDate($oNow->modify('+1 month'));

return $instance;

}

How to use a callback with SonataAdminBundle sonata_type_model_autocomplete in configureFormFields

By Houssem on 25 May 2017 in Symfony

The callback in sonata_type_model_autocomplete configuration is a callable function that can be used to modify the query which is used to retrieve autocomplete items. The callback should receive three parameters – the Admin instance, the property (or properties) defined as searchable and the search value entered by the user.

                $formMapper->add('category', 'sonata_type_model_autocomplete', array(
                    'property' => 'name',
                    'multiple' => false,
                    'required' => false,
                    'callback' => function ($admin, $property, $value) {
                        $datagrid = $admin->getDatagrid();
                        $queryBuilder = $datagrid->getQuery();
                        $queryBuilder
                            ->andWhere($queryBuilder->getRootAlias() . '.position=:posValue')
                            ->andWhere($queryBuilder->getRootAlias() . '.context=:contextValue')
                            ->setParameter('posValue', 0)
                            ->setParameter('contextValue', 'store')
                        ;
                        $datagrid->setValue($property, null, $value);
                    },
                ))

$formMapper->add('category', 'sonata_type_model_autocomplete', array(

'property' => 'name',

'multiple' => false,

'required' => false,

'callback' => function ($admin, $property, $value) {

$datagrid = $admin->getDatagrid();

$queryBuilder = $datagrid->getQuery();

$queryBuilder

->andWhere($queryBuilder->getRootAlias() . '.position=:posValue')

->andWhere($queryBuilder->getRootAlias() . '.context=:contextValue')

->setParameter('posValue', 0)

->setParameter('contextValue', 'store')

;

$datagrid->setValue($property, null, $value);

))

Add join with custom database table in hook_views_query_alter()

By Houssem on 27 November 2013 in Drupal

In this example i would add a join to the database table “node” with an other database table “event_submissions” which i created in my custom module, so i will add a hook_views_query_alter() function in mymodule.module file :

  if($view->name === 'event_calendar' && $view->current_display === 'event_month_calendar'){
    global $user;
    $join_def['table'] = 'event_submissions';
    $join_def['field'] = 'nid';
    $join_def['left_table'] = 'node';
    $join_def['left_field'] = 'nid';
    $join_def['extra'] = 'es.uid = ' . $user->uid . ' AND es.canceled = 0';

    $join = new views_join();

    $join->definition = $join_def;
    $join->construct();
    $join->adjusted = TRUE;

    $view->query->add_relationship('es', $join);
    $query->add_where(0, 'es.uid', '', 'IS NOT NULL');
  }

if($view->name === 'event_calendar' && $view->current_display === 'event_month_calendar'){

global $user;

$join_def['table'] = 'event_submissions';

$join_def['field'] = 'nid';

$join_def['left_table'] = 'node';

$join_def['left_field'] = 'nid';

$join_def['extra'] = 'es.uid = ' . $user->uid . ' AND es.canceled = 0';

$join = new views_join();

$join->definition = $join_def;

$join->construct();

$join->adjusted = TRUE;

$view->query->add_relationship('es', $join);

$query->add_where(0, 'es.uid', '', 'IS NOT NULL');

}

This code allows me to get the events that the current user had participated.

Create a class to consume soap web service

By Houssem on 12 November 2013 in PHP

There is an example of class to show you how to write code to consume a SOAP based web service.

In the code below a demo of how to instanciate this class and call the RequestSW method :

    $wsdl_path = "url_to_wsdl";    
    $oMySC = new mySC($wsdl_path);

    $params= array(val1, val2, val3, val4);

    $my_soap_client_obj = $oMySC->RequestSW('method_name', $params);

$wsdl_path = "url_to_wsdl";

$oMySC = new mySC($wsdl_path);

$params= array(val1, val2, val3, val4);

$my_soap_client_obj = $oMySC->RequestSW('method_name', $params);

Alter captcha field with the hook_element_info_alter()

By Houssem on 19 October 2013 in Drupal

If you want to change the field properties of the Captcha module or the Image CAPTCHA module you will see that this is not possible with hook_form_alter () because through this function we can not access to the fields of the captcha, the picture below shows an example of what you get when we display the variable $form in […]

Advanced example of using the “for” and “loop” in twig

By Houssem on 25 September 2013 in Twig

This example illustrate how to use a nested “for” in twig also the use of a loop instruction:

<ul>     
  {% for child in childs %}
    <li>
      <span>{{child.name}}</span>
      <ul style="list-style: square;padding-left: 20px;">
        {% for item in items[child.id] %}
          {% if loop.index < 4 %}
            <li><span>{{ item.title }}</span></li>
          {% else %}
            <li style="display:none;"><span>{{ item.title }}</span></li>
          {% endif %}
        {% endfor %}
      </ul>
    </li>     
  {% endfor %}
</ul>

<ul>

{% for child in childs %}

<li>

{{child.name}}

{% for item in items[child.id] %}

{% if loop.index < 4 %}

<li>{{ item.title }}</li>

{% else %}

<li style="display:none;">{{ item.title }}</li>

{% endif %}

{% endfor %}

</ul>

</li>

{% endfor %}

</ul>

Inside of a for loop block you can access some special variables: Variable Description loop.index The current iteration of the loop. (1 indexed) loop.index0 The current iteration of the loop. (0 indexed) loop.revindex The number of iterations from […]

How to use the Intl Extension Twig for date

By Houssem on 25 September 2013 in Twig

First you should install the php5-intl :

sudo apt-get install php5-intl

1	sudo apt-get install php5-intl

Then add the code below in your “app/config/config.yml” file :

services:
    twig.extension.intl:
        class: Twig_Extensions_Extension_Intl
        tags:
            - { name: twig.extension }

services:

twig.extension.intl:

class: Twig_Extensions_Extension_Intl

tags:

- { name: twig.extension }

Finaly in you twig file you can use the localizeddate filter to format dates into a localized string representating the date :

{{ post.published_at|localizeddate('medium', 'none', locale) }}

1	{{ post.published_at\|localizeddate('medium', 'none', locale) }}
