SuggestBundle

About

This is a Symfony bundle which enables the popular Select2 component to be used as a drop-in replacement for a standard entity, document and choice fields on a Symfony form.

The main feature of this bundle is that the list of choices is retrieved via a remote ajax call.

1. Installation

Add the sirian/suggest-bundle package to your require section in the composer.json file.

$ composer require sirian/suggest-bundle

Add the SuggestBundle to your application's kernel:

<?php
public function registerBundles()
{
    $bundles = array(
        // ...
        new Sirian\SuggestBundle\SirianSuggestBundle(),
        // ...
    );
    ...
}

2. Configuration

After installing the bundle, make sure you add this route to your routing:

# app/config/routing.yml

_sirian_suggest:
    resource: "@SirianSuggestBundle/Resources/config/routing.yml"
    prefix:   /suggest

And choose default widget for form (depends on select2 version you use). One of select2_v3, select2_v4. You could also specify other default form options for SuggestType::class

# app/config/config.yml

...
sirian_suggest:
    form_options:
        widget: select2_v4
        attr:
            placeholder: "Search..."

3. Configuring suggesters

3.1. Doctrine ODM Document suggesters

# app/config/config.yml

...
sirian_suggest:
    odm:
        category:
            class: "MainBundle:Category"
            property: name
        
        user:
            class: "MainBundle:User"
            property: username
            search:
                email: ~
                username: ~

3.2. Doctrine ORM Entity suggesters

# app/config/config.yml

...
sirian_suggest:
    orm:
        category:
            class: "MainBundle:Category"
            property: name
        
        user:
            class: "MainBundle:User"
            property: username
            search:
                email: ~
                username: ~

3.3. Custom suggesters

When you need some additional logic - you could create your own suggester. For example let's create AdminSuggester which suggests only users having ROLE_ADMIN role

<?php

namespace App\MainBundle\Suggest;

use App\MainBundle\Document\User;
use Doctrine\Common\Persistence\ManagerRegistry;
use Sirian\SuggestBundle\Suggest\DocumentSuggester;
use Sirian\SuggestBundle\Suggest\Item;
use Sirian\SuggestBundle\Suggest\SuggestQuery;

class AdminSuggester extends DocumentSuggester
{
    public function __construct(ManagerRegistry $registry)
    {
        $options = [
            'class' => User::class,
            'id_property' => 'id',
            'property' => 'username',
            'search' => [
                'name' => DocumentSuggester::SEARCH_MIDDLE,
                'username' => DocumentSuggester::SEARCH_MIDDLE,
                'email' => DocumentSuggester::SEARCH_MIDDLE
            ]
        ];

        parent::__construct($registry, $options);
    }

    protected function createSuggestQueryBuilder(SuggestQuery $query)
    {
        $qb = parent::createSuggestQueryBuilder($query);
        
        $qb->field('roles')->equals('ROLE_ADMIN');
        
        return $qb;
    }

    protected function transformObject($user)
    {
        $item = new Item();
        $item->id = $user->getId();
        $item->text = $user->getName() . ' ( ' . $user->getUsername() . ', ' . $user->getEmail() . ')';

        return $item;
    }
}

Define service services.yml with sirian_suggest.suggester tag

    app.suggester.admin:
        class: App\MainBundle\Suggest\AdminSuggester
        arguments: ["@doctrine_mongodb"]
        tags: 
            - {name: 'sirian_suggest.suggester', alias: 'admin'}

Alias admin will be used in suggester option for SuggestType::class and in /suggest/admin url pattern.

4. Using

Now you can use configured suggesters in forms

$formBuilder->add('category', SuggestType::class, [
    'suggester' => 'category'
])

5. Security

You could restrict access to suggesters by securing URL patterns

security:
   ...
   access_control:
        ...
        - { path: ^/suggest/category, roles: ROLE_USER }
        - { path: ^/suggest, roles: ROLE_ADMIN }

6. Passing additional options to suggester

Sometimes you need to pass additional parameters to Suggester.

6.1. Static extra options

Let's start with simple example. You have brands and models and you want to display only models for one specific brand. Create class ModelSuggester

<?php

namespace App\MainBundle\Suggest;

use App\MainBundle\Document\Model;
use Doctrine\Common\Persistence\ManagerRegistry;
use Sirian\SuggestBundle\Suggest\DocumentSuggester;
use Sirian\SuggestBundle\Suggest\SuggestQuery;

class ModelSuggester extends DocumentSuggester
{
    public function __construct(ManagerRegistry $registry)
    {
        $options = [
            'class' => Model::class,
            'id_property' => 'id',
            'property' => 'name',
        ];

        parent::__construct($registry, $options);
    }

    protected function createSuggestQueryBuilder(SuggestQuery $query)
    {
        $qb = parent::createSuggestQueryBuilder($query);
        
        $brandId = $query->extra['brand_id'];
        
        $qb->field('brand')->equals($brandId);
        
        return $qb;
    }
}

Define service

    app.suggester.model:
        class: App\MainBundle\Suggest\ModelSuggester
        arguments: ["@doctrine_mongodb"]
        tags: 
            - {name: 'sirian_suggest.suggester', alias: 'model'}

and add extra option to form options:

$formBuilder->add('model', SuggestType::class, [
    'suggester' => 'model',
    'extra' => [
        'brand_id' => 123
    ]
])

6.2. Dynamic extra options

Now let's see an example when you have 2 suggest fields brand and model and in second select you want to display models for selected brand.

You need to create ModelSuggester and define suggester service (like in previous section).

And then customize form widget to pass brand_id extra option to suggester

{% block _form_model_widget %}
    {{ form_widget(form) }}
    
    <script>
        (function () {
            // get prepared options for select2
            var options = $('#{{ id }}').data('suggest-options');
            
            // update ajax.data option 
            options.ajax.data = function (term, page) {
                return {
                    q: term,
                    page: page,
                    extra: {
                        brand_id: $('#form_brand').val() // get brand_id from another select 
                    }
                }
            }
        }());
    </script>
{% endblock %}
