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);

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 :
