本文介绍了使用andwhere()的Symfony2 / Doctrine QueryBuilder的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

我在存储库类中使用以下方法在数据库中查找某些标签:

I am using following method in a repository class to look for certain tags in my database:

public function getItemsByTag($tag, $limit = null)
{
    $tag = '%'.$tag.'%';

    $qb = $this->createQueryBuilder('c');

    $qb->select('c')
       ->where($qb->expr()->like('c.tags', '?1'))
       ->setParameter(1, $tag)
       ->addOrderBy('c.clicks', 'DESC');

    if (false === is_null($limit))
        $qb->setMaxResults($limit);

    return $qb->getQuery()->getResult();
}

这很好用。但是:如何添加2个其他变量(其中:已审核= 1,启用= 1)?我尝试了andwhere(),但我想不通。

This works just nice.. But: How can I add 2 additional variables (where: reviewed = 1, enabled = 1)? I tried andwhere() but I couldn't figure it out.

我还发现类似这样的东西:

I also found out that something like this:

public function getItems($limit = null)
{
        $qb = $this->createQueryBuilder('b')
               ->select('b')
               ->add('where', 'b.reviewed = 1')
               ->add('where', 'b.enabled = 1')
               ->addOrderBy('b.name', 'ASC');

        // ...
}

不会

有什么提示吗?

推荐答案

像这样写:

$qb = $this
    ->createQueryBuilder('c')
    ->where('c.tags LIKE :tag')
    ->andWhere('c.reviewed = 1')
    ->andWhere('c.enabled = 1')
    ->setParameter('tag', "%{$tag}%")
    ->orderBy('c.clicks', 'DESC')
    ->addOrderBy('b.name', 'ASC');

if ($limit) {
    $qb->setMaxResults($limit);
}

return $qb->getQuery()->getResult();

您也可以在条件为$code>的情况下团结那些

You could also unite those where conditions:

->where('c.tags LIKE :tag AND c.reviewed = 1 AND c.enabled = 1')
