Zend多個位置

Question

我有下一個代碼，但是他不起作用：

$select_sell = $this->select();
$select_sell->from($this->_name, array('rank_id'))
            ->where('rank_id = ?', $id)
            ->where('type = ?', 'must_sell');
$result = $this->fetchAll($select_sell)->count();

我需要進行此查詢... WHERE rank_id = $id AND type = 'must_sell'..

謝謝玩具。

Answer 1

正如戈登在他的評論中所說，type不是變量：

$select_sell = $this->select();
$select_sell->from($this->_name, array('rank_id'))
            ->where('rank_id = ?', $id)
            ->where('type = "must_sell"');
$result = $this->fetchAll($select_sell)->count();

幾次遇到這個問題。 你可以這樣解決

$select_sell = $this->select();
$select_sell->from($this->_name, array('rank_id'))
    ->where("(rank_id = $id AND type = 'must_sell')");
