Symfony4 / Doctrine2上具有可变数量标准的表格

Question

Let's take https://symfony.com/doc/current/forms.html#building-the-form example form but only for Search in tasks list instead of save.

Goal is to allow searches on task, dueDate or both criterias (in my real case, I have 9 criterias)

Here are src/Repository/ResultRepository.php :

class ResultRepository extends ServiceEntityRepository
{
    public function __construct(RegistryInterface $registry)
    {
        parent::__construct($registry, Result::class);
    }

    public function findMultiKeys($task, $dueDate): array
    {
        $qb = $this->createQueryBuilder('d')
            ->andWhere('d.task = :task')
            ->setParameter('task', $task)
            ->andWhere('d.dueDate = :dueDate')
            ->setParameter('dueDate', $dueDate)
            ->getQuery();

        return $qb->execute();
    }   
}

It require both criterias to return result(s)!

Answer 1

I ran a lot of searches and find:

• How do I use a complex criteria inside a doctrine 2 entity's repository?
• Symfony2/Doctrine QueryBuilder using andwhere()
• Doctrine2 doc - setParameters method

So I code a $where_string variable to construct my variable where. and a $parameters to construct my variable parameters array, and my findMultiKeys becomes:

public function findMultiKeys($get_form): array
{
    $where_string = '';
    $parameters = [];
    $task = $get_form->getTask();
    if ($task !== null) {
        $where_string .= "d.task = :task";
        $parameters += array('task' => $task);
    }
    $dueDate = $get_form->getDueDate();
    if ($dueDate !== null) {
        if ($where_string !== '')
            $where_string .= " AND ";
        $where_string .= "d.dueDate = :dueDate";
        $parameters += array('dueDate' => $dueDate);
    }

    $qb = $this->createQueryBuilder('d')
        ->where($where_string)
        ->setParameters($parameters)
        ->getQuery();

    return $qb->execute();
}   

It works, perhaps not the best way? In my searches, I found, of course, to use ElasticSearch , perhaps to much to my simple need, or I found PetkoparaMultiSearchBundle

Answer 2

I have a proposition :-)

1. You can build an task4Seach entity with your 9 criteria (without persistance)

2. create a form type with this "data_class"

3. use it to get your datas in your repository

 $qb = $this->createQueryBuilder('d'); ... if ($task4Seach ->getDueDate()) { $qb->andWhere($qb->expr()->eq('d.dueDate', ':dueDate')); $qb->setParameter('dueDate', $task4Seach->getDueDate()); }
