Question

我想知道是否可以使用类似于以下内容的方法从数据库中检索行：

    if (!empty($this->params['form'])) {
        $place = array();
        $place['city'] = $this->params['form']['city'];
        $place['area'] = $this->params['form']['state'];
        $place['country'] = $this->params['form']['country'];
        $place['iso'] = $this->params['form']['iso'];

        $this->Place->set($place);
        $place_found = $this->Place->read();
    }

我是否可以使用数组预设Place模型中的数据，然后使用Place read。我正在寻找像往常一样简单的东西：

$this->Place->id = 7;
$place_found = $this->Place->Read();

我也试过这样做：

$this->Place->city = blah;
$this->Place->area = foo; etc....

$place_found = $this->Place->read();

然而，这也行不通。

Answer 1

你有没有用过find()？！ read()仅获取传递了ID的行。

$place_found = $this->Place->find('first', array(
    'conditions' => array(
          'Place.city' => $city,
          'Place.area' => $area
          // etc
     )
));

如果需要手动构建条件，可以创建一个条件数组，如下所示：

$placeConditions = array();
$placeConditions['city'] = $city;
if($area) {
    $placeConditions['area'] = $area;
}

$places = $this->Place->find('first', array('conditions' => $placeConditions));

我建议您阅读我关联的网页，您很快就会发现没有理由使用read()方法。

Answer 2

在模型中你可以做到：

$this->id = 3; //place id
$this->Place->read();

希望有所帮助

Answer 3

我认为这种方法正是您所需要的（使用您的代码）：

if (!empty($this->params['form'])) {
    $place = array();
    $place['city'] = $this->params['form']['city'];
    $place['area'] = $this->params['form']['state'];
    $place['country'] = $this->params['form']['country'];
    $place['iso'] = $this->params['form']['iso'];

    //$this->Place->set($place); //don't need it here I think
    $place_found = $this->Place->find('all',array('conditions'=>$place));
}

使用cakephp中的read（）来检索包含数据数组的行
