1. Create BlobType.php file in Symfony/vendor/doctrine-dbal/lib/Doctrine/DBAL/Types/
   

   namespace Doctrine\DBAL\Types;
   
   use Doctrine\DBAL\Platforms\AbstractPlatform;
   
   class BlobType extends Type
   {
       const BLOB = 'blob';
   
       public function getName()
       {
           return self::BLOB;
       }
   
       public function getSQLDeclaration(array $fieldDeclaration, AbstractPlatform $platform)
       {
           return $platform->getDoctrineTypeMapping('BLOB');
       }
   
       public function convertToDatabaseValue($value, AbstractPlatform $platform)
       {
           return ($value === null) ? null : base64_encode($value);
       }
   
       public function convertToPHPValue($value, AbstractPlatform $platform)
       {
           return ($value === null) ? null : base64_decode($value);
       }
   }
   ?>
   

2. In Symfony/vendor/doctrine-dbal/lib/Doctrine/DBAL/Types/Type.php add
   

            const BLOB = 'blob';
            self::BLOB => 'Doctrine\DBAL\Types\BlobType', to $_typesMap array;
            

3. Add this method to your class in DomainYourBundle.php in Symfony/src/YourDomain/YourBundle/
   

       public function boot()
       {
           $em = $this->container->get('doctrine.orm.entity_manager');
           if (!Type::hasType('blob'))
           {
               Type::addType('blob', 'Doctrine\DBAL\Types\Type\BlobType');
               $em->getConnection()->getDatabasePlatform()->registerDoctrineTypeMapping('blob','blob');
           }
       }
   

<input type="radio" id="button1" name="repeat" checked="checked" class="ui-button ui-button-text-only ui-widget ui-state-default ui-corner-all"/><label for="button1" id="button1Label">button1</label>

<input type="radio" id="button2" name="repeat" checked="checked" class="ui-button ui-button-text-only ui-widget ui-state-default ui-corner-all"/><label for="button2" id="button2Label">button2 is long</label>

and in javascript code:

var button1 = $('#button1').button();
var button2 = $('#button2').button();

$('#button1Label').width(200);
$('#button2Label').width(200);

In this post i show how i used symfony2, dojio and to validate a form loaded via ajax and how to change the size and other properties of ValidationTextBox.

This is a form loaded via ajax :

{% extends ‘::base.html.twig’ %}
{% block javascripts %}
{% endblock %}
{% block body %}

<form action=”{{ path(‘NdfExampleBundle_people’) }}” method=”post” {{ form_enctype(form) }} id=”forminsertpeople” dojoType=”dijit.form.Form”>

{{ form_widget(form.ci , { ‘attr’: {‘labelAttr’: ‘ci’,'labelType’:'html’,'dojoType’:'dijit.form.ValidationTextBox’,'maxLength’:’12′,
‘regExp’:'\\w{12}’,'invalidMessage’: ‘CI must to be 12 characters’} }) }}

<button dojoType=”dijit.form.Button” type=”submit” name=”submitButtonSave”
value=”Submit”>
Save
</button>

<img src=”404.gif” style=”position:absolute;width:0px;height:0px” onerror=”refreshPeople()”>
{% endblock %}

The main page must  contain refreshPeople()

function refreshPeople() {

  try {
    dijit.byId('forminsertpeople').destroy();
  }
  catch (ex) {
  }

  // Change Width

  var dum = dojo.byId('form_ci');
  dojo.style(dum, "width", "12em");

  dojo.parser.parse(dojo.byId('your_target'));

  // Change maxLength

  dum = dijit.byId('form_cognome');
  dum.set( "maxlength", 20);

  dojo.addOnLoad(function () {

  var connectForm = dojo.byId("forminsertpeople");
  dojo.connect(connectForm, "onsubmit", function (e) {
  // connect to, and disable the submit of this form
  e.preventDefault();
  // post the form with all it's defaults
  var mainForm = dijit.byId( "forminsertpeople" );
  dojo.stopEvent(event);
  if ( mainForm.validate() ) {

    var form = dojo.byId("forminsertpeople");
    dojo.xhrPost({
    form:form,
    load:function (data) {
      // set the form's HTML to be the response

      form.innerHTML = data;

     }
   });
  }
});
});
dojo.parser.parse(dojo.byId('forminsertpeople'));
}

Note how the style changes are made before  dojo.parser.parse(dojo.byId(‘your_target’));
after instead the changes to the attributes of the validator.
