Zend Framework join

问题:

I've been struggle for hours with the follow join issue in Zend Framework.

My table(s)

• Table (websites)

  • id
  • user_id
  • website
  • url
  • ...

• Table (users)

  • id
  • username
  • salt
  • password
  • ...

• Table (reviews)

  • id
  • website_id (id of website)
  • user_id (id from the user/owner of the website)
  • reviewer_id (id from the user who has reviewed the website)
  • review
  • ...

What do I want to get..
To make a array with join of the review and user data is no problem, but I want also add the website compare to the review.

I made the follow join but I won't work like I want, I have just 3 test reviews in my database and I'm getting over 12 results in my array.

My query:

$select = $this->_db->select() ->from('reviews') ->joinLeft('users', 'reviews.reviewer_id = users.id') ->joinLeft('websites', 'reviews.user_id = reviews.user_id') ->where("reviews.user_id = $user_id");

$result = $this->getAdapter()->fetchAll($select);

With kind regards,

Nicky

Try adding a groupBy to your query (untested)

$select = $this->_db->select()->from('reviews')
                              ->joinLeft('users', 'reviews.reviewer_id = users.id')
                              ->joinLeft('websites', 'reviews.user_id = reviews.user_id')
                              ->where("reviews.user_id = $user_id")
                              ->group('reviews.id');
