Question

I am making a Zend framework method for a search engine. Because i search through different tables i also have to make two different select variables and return it. My questions are: Is this a good idea for a search engine with different tables?

And how to return the different resuls in an array? (fetchall->$selectMovies, fetchall->$selectPosts)

Thanks and greetz Eric

public function search($keyword) {
        $selectPosts = $this->select();
        $selectPosts->from('posts', array('*'));
        $selectPosts->where('posts.post_title LIKE ? OR  posts.post_body LIKE ?', '%'. $keyword . '%' );

        $tblMovies = new Model_DbTable_Film();
        $selectMovies = $tblMovies->select();
        $selectMovies->from('film', array('*'));
        $selectMovies->where('film.titel LIKE ? OR  film.omschrijving LIKE ?', '%'. $keyword . '%' );

        //var_dump($this->fetchAll($selectPosts, $selectMovies)); die;
        return $this->fetchAll($selectMovies);
        return $this->fetchAll($selectPosts); 

    }

You can only return once, but what you can do is return an array of your result arrays.

<?php 
public function search($keyword) {
    $selectPosts = $this->select();
    $selectPosts->from('posts', array('*'));
    $selectPosts->where('posts.post_title LIKE ? OR  posts.post_body LIKE ?', '%'. $keyword . '%' );

    $tblMovies = new Model_DbTable_Film();
    $selectMovies = $tblMovies->select();
    $selectMovies->from('film', array('*'));
    $selectMovies->where('film.titel LIKE ? OR  film.omschrijving LIKE ?', '%'. $keyword . '%' );

    //var_dump($this->fetchAll($selectPosts, $selectMovies)); die;

    return array('movies'=>$this->fetchAll($selectMovies),
                 'posts'=>$this->fetchAll($selectPosts));
}
?>

Or split up your method into 2 and pass a type of search as a parameter to the main search method:

<?php 
public function search($keyword,$type) {
    return $this->{$type}($keyword);
}

public function search_movies($keyword) {
    $tblMovies = new Model_DbTable_Film();
    $selectMovies = $tblMovies->select();
    $selectMovies->from('film', array('*'));
    $selectMovies->where('film.titel LIKE ? OR  film.omschrijving LIKE ?', '%'. $keyword . '%' );
    return $this->fetchAll($selectMovies);
}

public function search_posts($keyword) {
    $selectPosts = $this->select();
    $selectPosts->from('posts', array('*'));
    $selectPosts->where('posts.post_title LIKE ? OR  posts.post_body LIKE ?', '%'. $keyword . '%' );
    return $this->fetchAll($selectPosts);
}
?>

<?php 
$result['movies'] = $model->search($keyword,'search_movies');
$result['posts'] = $model->search($keyword,'search_posts');
?>
