Add Form

Add a FormType for a Sylius Resource

Ask the user for the ModelName if not provided. Read src/**/Entity/{ModelName}/{ModelName}.php to detect the entity's fields.

Prerequisite: the model must already exist as a Sylius Resource (run /sylius-app:add-model first).

1. Create the FormType

src/Form/Type/{ModelName}/{ModelName}Type.php:

<?php

declare(strict_types=1);

namespace App\Form\Type\{ModelName};

use Sylius\Bundle\ResourceBundle\Form\Type\AbstractResourceType;
use Symfony\Component\Form\FormBuilderInterface;

final class {ModelName}Type extends AbstractResourceType
{
    public function buildForm(FormBuilderInterface $builder, array $options): void
    {
        $builder
            // add fields based on the entity properties
        ;
    }

    public function getBlockPrefix(): string
    {
        return 'app_{model_snake}';
    }
}

Read the entity fields and add the appropriate Symfony form types for each one (e.g. TextType, TextareaType, IntegerType, CheckboxType, etc.). Label each field with app.form.{model_snake}.{field}:

$builder
    ->add('name', TextType::class, [
        'label' => 'app.form.{model_snake}.name',
    ])
    ->add('enabled', CheckboxType::class, [
        'label' => 'app.form.{model_snake}.enabled',
    ])
;

2. Register the service

Add to config/services.yaml:

services:
    app.form.type.{model_snake}:
        class: App\Form\Type\{ModelName}\{ModelName}Type
        arguments:
            - '%app.model.{model_snake}.class%'
            - ['sylius']
        tags:
            - { name: form.type }

3. Declare the form in the resource config

Edit config/packages/sylius_resource.yaml. Add form: under the existing classes: for app.{model_snake}:

sylius_resource:
    resources:
        app.{model_snake}:
            driver: doctrine/orm
            classes:
                model: App\Entity\{ModelName}\{ModelName}
                interface: App\Entity\{ModelName}\{ModelName}Interface
                form: App\Form\Type\{ModelName}\{ModelName}Type

4. Translation keys

Get the project's default locale:

bin/console debug:container --parameter=kernel.default_locale

Add labels to translations/messages.{locale}.yaml under app.form.{model_snake}.{field} (one entry per field declared in the FormType):

app:
    form:
        {model_snake}:
            name: Name
            enabled: Enabled
            # one entry per field

5. Clear cache

bin/console cache:clear

6. Verify

• bin/console debug:form "App\Form\Type\{ModelName}\{ModelName}Type" lists the declared fields
• bin/console debug:translation {locale} --domain=messages 2>&1 | grep 'app.form.{model_snake}' lists every field label you added.

Next steps

• /sylius-app:add-grid to add the admin index grid
• Then /sylius-app:add-routes and /sylius-app:add-menu to wire it into the admin
• /sylius-app:add-images if the model needs an images collection
• /sylius-app:add-autocomplete to expose the model as a searchable field in another form
