如何在cakephp中的另一个条件内使用条件

Question

我有一个答案。 我也有两个ID，即男人和女人的ID字段在另一个表中的名称为ca_field_id 。

我的要求是我要在以下条件下获取数据

1. 既有男人（id = 37）又有女人（id = 38）
2. 年龄67
3. 女性年龄65

但是我得到的数据都是67岁的男性和67岁的女性，反之亦然。

用下面的查询：

$numberofemployeesmen = 37;
$numberofemployeeswomen =38;

$caanswer = $this->CaAnswer->find('all', 
    array(
        'conditions' => array(
            'CaAnswer.ca_field_id' => array($numberofemployeesmen,$numberofemployeeswomen),
            'CaAnswer.answer' => array(67,65)
         )
     )
 );

我也尝试了如下但没有用

$numberofemployeesmen = 37;
$numberofemployeeswomen =38;

$caanswer = $this->CaAnswer->find('all', 
    array('conditions' => array(
        'CaAnswer.ca_field_id' => array($numberofemployeesmen,$numberofemployeeswomen),
        'CaAnswer.answer'=> array(
            67 AND array('CaAnswer.ca_field_id' =>$numberofemployeesmen),
            65 AND array('CaAnswer.ca_field_id'=>$numberofemployeeswomen))
        )
    )
 );

请告诉我我该如何解决...

Answer 1

尝试这个：

$numberofemployeesmen = 37;
$numberofemployeeswomen = 38;

$caanswer = $this->CaAnswer->find('all', 
    [
        'conditions' => [
            'OR' => [
                [
                    'CaAnswer.ca_field_id' => $numberofemployeesmen,
                    'CaAnswer.answer' => 67
                ],
                [
                    'CaAnswer.ca_field_id' => $numberofemployeeswomen,
                    'CaAnswer.answer' => 65
                ],
             ]
         ]
     ]
 );

如果这不起作用，则可能需要在OR内添加其他AND键：

$caanswer = $this->CaAnswer->find('all', 
    [
        'conditions' => [
            'OR' => [
                [
                    'AND' => [
                        'CaAnswer.ca_field_id' => $numberofemployeesmen,
                        'CaAnswer.answer' => 67
                    ],
                ],
                [
                    'AND' => [
                        'CaAnswer.ca_field_id' => $numberofemployeeswomen,
                        'CaAnswer.answer' => 65
                    ],
                ],
             ]
         ]
     ]
 );

请注意，在此示例中， AND位于其自己的数组内，因此第二个AND键不会覆盖第一个。

想法是，您说的是我要第一组AND条件或第二组AND条件。 但是在每个方面，两个条件都需要满足。

可能不完全正确，但是这些应该可以让您了解如何完成此操作。 （就从我头顶上跳下来）。

Answer 2

你有没有尝试过

$caanswer = $this->CaAnswer->find('all', 
    array('conditions' => array(
        'CaAnswer.ca_field_id' => array($numberofemployeesmen,$numberofemployeeswomen),
        'CaAnswer.answer'=> array(
            67 AND array('CaAnswer.ca_field_id' =>0),
            65 AND array('CaAnswer.ca_field_id'=>1))
        )
    )
 );

如果我没记错的话，array（$ numberofemployeesmen，$ numberofemployeeswomen）创建一个像这样的数组0 => $ numberofemployeesmen 1 => $ numberofemployeeswomen
