Symfony Native Form Builder Bundle

This bundle allows you to to create native forms on-the-fly right at your twig file without defining the form in controller/service.

Installation

composer require starx/symfony-native-form-builder

Enable the bundle

Enable your bunndle from your AppKernel.php

public function registerBundles() {
    $bundles = [
        ...,
        new Starx\SymfonyNativeFormBuilderBundle\StarxSymfonyNativeFormBuilderBundle()
    ];

    ...
    return $bundles;
}

Usages

In any twig file:

{%  
    set native_form = native_form_builder.getNativeFormView(
        path('your_route', {
            'id': user.id
        }),
        "GET"
) %}
{{ form_start(native_form) }}
    <input class="btn btn-sm" type="submit" value="Submit" />
{{ form_end(native_form) }}

This will create a native form without any previous declaration in controller/service.

Examples

1. Quick delete form In any twig file:

   {%
       set native_delete_form = native_form_builder.getNativeFormView(
           path('your_route_delete_action', {
               'id': user.id
           }),
           "DELETE"
   ) %}
   {{ form_start(native_delete_form) }}
       <input class="btn btn-sm" type="submit" value="Delete"
          onClick="return confirm('Are you sure?')"
       />
   {{ form_end(native_delete_form) }}

   This will generate a quick delete form in your twig file with a single button and a CSRF token with DELETE http method, which is recommended way to delete a entity.

2. Generating a quick form based on a predefined form type when you want to show list of entities with a small inline form on the side

   <table>
       <thead>
           ...
       </thead>
       <tbody>
           {% for entity in entities %}
               {%
                   set native_update_form = native_form_builder.getNativeFormView(
                       path('your_enity_edit_action', {
                           'id': user.id
                       }),
                       "POST",
                       'AppBundle\\Form\\EntityType',
                       entity
                   )
               %}
               <tr>
                   <td>
                       {{ entity.id }}
                   </td>
                   <td>
                       {{ entity.name }}
                   </td>
                   <td>
                       {{ form_start(native_update_form) }}
                           {{ form_widget(native_update_form.value_field) }}
                           <input class="btn btn-sm" type="submit" value="Update" />
                       {{ form_end(native_update_form) }}
                   </td>
               </tr>
           {% endfor %}
       </tbody>
   </table>

   This will generate quick update forms in your twig template file where you are showing list of entities showing only one field required to update.

Note:

I do understand that such use case in twig is discouraged, but other wise to solve such requirement you would have to

• loop through the entities in controller
• Manually create all the forms for each of those entities
• Pass them in a view/twig variables to your twig template file and
• Once again, loop through them again in twig file.

Instead of doing all this, as long as you don't over do it, simple use case as above should be justified.
