doctrine.countArgument - Phpstan

Code example

php

<?php declare(strict_types = 1);

use Doctrine\ORM\EntityManager;
use Doctrine\ORM\Mapping as ORM;

#[ORM\Entity]
class User
{
	#[ORM\Id]
	#[ORM\Column]
	public int $id;

	#[ORM\Column]
	public string $name;
}

function doFoo(EntityManager $em): void
{
	$repository = $em->getRepository(User::class);
	$repository->count(['nonexistent' => 'test']);
}

Why is it reported?

The count() method on a Doctrine entity repository accepts an array of field names to filter by. The field nonexistent does not exist on the User entity, so the call will fail at runtime with a Doctrine exception.

This rule is provided by the phpstan-doctrine extension.

How to fix it

Use a field name that actually exists on the entity:

diff-php

- $repository->count(['nonexistent' => 'test']);
+ $repository->count(['name' => 'test']);
