Installation

Download the bundle with composer

    composer require alsatian/form-bundle

Enable the bundle

Add the bundle to app/AppKernel.php :

// app/AppKernel.php

class AppKernel extends Kernel
{
    public function registerBundles()
    {
        $bundles = array(
            // ...

            new Alsatian\FormBundle\AlsatianFormBundle(),
        );

        // ...
    }

    // ...
}

Configuration

Add following lines to app/config/config.yml

alsatian_form:
    extensible_choice: ~   # To enable Alsatian\FormBundle\Form\ExtensibleChoiceType
    extensible_entity: ~   # To enable Alsatian\FormBundle\Form\ExtensibleEntityType
    extensible_document: ~ # To enable Alsatian\FormBundle\Form\ExtensibleDocumentType

For each FormType you can configure a default attr_class parameter, like this :

alsatian_form:
    extensible_choice:
        attr_class: select2 # Adds class="select2" in the HTML select element
    extensible_entity:
        attr_class: select2-entity # Adds class="select2-entity" in the HTML select element
    extensible_document:
        attr_class: select2-document # Adds class="select2-document" in the HTML select element

Usage

To use these FormTypes :

    use Alsatian\FormBundle\Form\ExtensibleChoiceType;
    use Alsatian\FormBundle\Form\ExtensibleEntityType;
    use Alsatian\FormBundle\Form\ExtensibleDocumentType;
    
    // Without route
    $builder->add('extensible_choice', ExtensibleChoiceType::class);
    $builder->add('extensible_entity', ExtensibleEntityType::class,array('class'=>'AppBundle:Article','choice_label'=>'name'));
    $builder->add('extensible_document', ExtensibleDocumentType::class,array('class'=>'AppBundle:Article','choice_label'=>'name'));

    // With route (generate the route defined as 'route' option and renders it as 'data-ajax-url' html attribute)
    $builder->add('extensible_choice', ExtensibleChoiceType::class,array('route'=>'ajax_choices'));
    $builder->add('extensible_entity', ExtensibleEntityType::class,array('route'=>'ajax_entities','class'=>'AppBundle:Article','choice_label'=>'name'));
    $builder->add('extensible_document', ExtensibleDocumentType::class,array('route'=>'ajax_documents','class'=>'AppBundle:Article','choice_label'=>'name'));

This will render HTML like :

<!-- if %alsatian_form.extensible_choice.attr_class% = 'select2' -->
<select data-ajax--url="%your_route%" class="select2">
</select>

The aim of this bundle is only to do the server side work (allowing "extensible" choices). You have to write your own Javescript adapters to get it work with Select2.

As example, how I use it :

$(document).ready(function(){
	$('.select2').each(function(){
		var configs={
		        allowClear: true,
		        width:'resolve',
			ajax:{
				data: function (params) {return {q: params.term};},
				dataType:'json',delay: 250,
				processResults: function (data) {
					var dataresults = [];
					$.each(data, function(key, val){
						dataresults.push({id: val[0], text: val[1]});
					});
					return { results: dataresults };
				}
			};
		};

		$(this).select2(configs);
	});
});
