README

A Symfony bundle for synchronizing Shopware custom field sets and fields from configuration files.

The bundle treats configuration as the single source of truth:

• custom field sets, fields and relations defined in config are created or updated
• anything that exists in the database but is not present in config is removed
• changes in field configuration (labels, components, options, etc.) are always applied
• deterministic UUIDs are generated from names

The bundle is designed to be used inside Shopware plugins and triggered from plugin lifecycle hooks (install, update).

Features

• Supports Shopware 6.6+
• Synchronizes:
  • custom field sets
  • custom fields
  • entity relations
• Supports config written in:
  • PHP
  • YAML
• Deterministic IDs based on names (stable across environments)
• No runtime options – simple and predictable behavior

⚠️ Renaming a custom field changes its technical name. Existing values stored in entity custom_fields JSON will not be migrated automatically. If you need data migration, handle it separately in your plugin.

Installation

Install via Composer:

composer require mich418/shopware-custom-fields-sync

Configuration format

Config file can define one or more custom field sets. Shopware Custom Fields Sync provides support for PHP and Yaml config format

PHP config example

<?php

use Shopware\Core\System\CustomField\CustomFieldTypes;

return [
    [
        'name' => 'product_extra',
        'config' => [
            'label' => [
                'en-GB' => 'Product Extra',
            ],
        ],
        'relations' => [
            ['entityName' => 'product'],
        ],
        'customFields' => [
            [
                'name' => 'subtitle',
                'type' => CustomFieldTypes::TEXT,
                'config' => [
                    'label' => [
                        'en-GB' => 'Subtitle',
                    ],
                    'componentName' => 'sw-text-field',
                    'customFieldPosition' => 1,
                ],
            ],
        ],
    ],
];

Yaml config example

- name: product_extra
  config:
    label:
      en-GB: Product Extra
  relations:
    - entityName: product
  customFields:
    - name: subtitle
      type: text
      config:
        label:
          en-GB: Subtitle
        componentName: sw-text-field
        customFieldPosition: 1

Notes

Field technical names are generated as: {setName}_{fieldName}

In YAML, type must be a valid Shopware custom field type string (text, int, bool, etc.).

Using the bundle in a Shopware plugin

1. Place the config file in your plugin

A example, you can put the file with a config in following path:

custom/plugins/MyPlugin/src/Resources/custom-fields.php

2. Trigger synchronization in plugin lifecycle

<?php declare(strict_types=1);

namespace MyPlugin;

use Shopware\Core\Framework\Plugin;
use Shopware\Core\Framework\Plugin\Context\InstallContext;
use Shopware\Core\Framework\Plugin\Context\UpdateContext;

use Mich418\ShopwareCustomFieldsSync\Sync\CustomFieldSetSynchronizerInterface;
use Mich418\ShopwareCustomFieldsSync\Config\CustomFieldsConfigLoaderInterface;

final class MyPlugin extends Plugin
{
    public function install(InstallContext $installContext): void
    {
        parent::install($installContext);
        $this->syncCustomFields($installContext->getContext());
    }

    public function update(UpdateContext $updateContext): void
    {
        parent::update($updateContext);
        $this->syncCustomFields($updateContext->getContext());
    }

    public function uninstall(UninstallContext $uninstallContext): void
    {
        parent::uninstall($uninstallContext);
        $this->removeCustomFields($uninstallContext);
    }

    private function syncCustomFields(\Shopware\Core\Framework\Context $context): void
    {
        $customFieldsConfig =  $this->container
            ->get(CustomFieldsConfigLoaderInterface::class)
            ->load(__DIR__ . '/Resources/custom-fields.php');

        $this->container
            ->get(CustomFieldSetSynchronizerInterface::class)
            ->sync($customFieldsConfig, $context);
    }

    private function removeCustomFields(\Shopware\Core\Framework\Context $context): void
    {
      $customFieldsConfig =  $this->container
            ->get(CustomFieldsConfigLoaderInterface::class)
            ->load(__DIR__ . '/Resources/custom-fields.php');

        $this->container
            ->get(CustomFieldSetSynchronizerInterface::class)
            ->remove($customFieldsConfig, $context);
    }
}

Synchronization rules (important)

During install or update:

• Sets, fields and relations defined in config are upserted
• Any existing field or relation not present in config is deleted
• Field configuration changes are always applied
• Stored values in entity custom_fields JSON are never deleted automatically
