Sonata Admin: modify validation groups in an admin extension

SonataAdminBundle has a powerful extensions feature which allows you to add or change features of one or more Admin instances.

I needed my extension to change some validation rules, and it turned out that imposing different validation groups was a good way to achieve it.

$formOptions attribute of Sonata\AdminBundle\Admin\AbstractAdmin class allows for setting validation groups, but I couldn’t find an easy way to modify it in my extension.

getFormBuilder method of AbstractAdmin class is where these $formOptions are added to the form builder:

	<?php

	// ....

	public function getFormBuilder()
	{
	$this->formOptions['data_class'] = $this->getClass();
	$formBuilder = $this->getFormContractor()->getFormBuilder(
	$this->getUniqid(),
	$this->formOptions
	);
	$this->defineFormBuilder($formBuilder);
	return $formBuilder;
	}

So, in my admin class I override this method, to add support for extensions:

	<?php

	// ....

	public function getFormBuilder()
	{
	$this->configureFormOptions(); // additional call that includes extensions

	$this->formOptions['data_class'] = $this->getClass();

	$formBuilder = $this->getFormContractor()->getFormBuilder(
	$this->getUniqid(),
	$this->formOptions
	);

	$this->defineFormBuilder($formBuilder);

	return $formBuilder;
	}

	public function configureFormOptions()
	{
	$extensions = $this->getExtensions();
	foreach ($extensions as $extension) {
	if (method_exists($extension, 'configureFormOptions')) {
	$this->formOptions = $extension->configureFormOptions($this->formOptions);
	}
	}
	}

	// ....

Now, in your admin extension you can add a method to actually modify $formOptions of the admin class:

	<?php

	// ....

	public function configureFormOptions(array $formOptions): array
	{
	$formOptions['validation_groups'] = ['myValidationGroup', 'anotherValidationGroup'];
	return $formOptions;
	}
