更新 CakePHP 中的记录（数组格式）

Question

如何保存此类数据？它给了我

Array to String conversion error. 

我的 asc201516s_teachers table 有以下列：

• teachers_name
• teachers_cnic
• teachers_gender
• teachers_contact。

我的数据数组是：

 [asc201516s_teachers] => Array
    (
        [teachers_name] => Array
            (
                [0] => asd asd 
                [1] => asd asd asd 
                [2] => asd asd asd asd 
            )

        [teachers_cnic] => Array
            (
                [0] => 32312-1212121-2
                [1] => 33434-3434343-4
                [2] => 34454-5454545-4
            )

        [teachers_gender] => Array
            (
                [0] => 1
                [1] => 2
                [2] => 2
            )            

        [teachers_contact] => Array
            (
                [0] => 1234-5678910
                [1] => 2345-6789101
                [2] => 3456-7891011
            )

    )

Answer 1

在CakePHP中保存多条记录的正确方法2.x如下：

$data=array(
    '0' => array(
        'teachers_name'=>'asd asd',
        'teachers_cnic'=>'32312-1212121-2',
        'teachers_gender'=>'1',
        'teachers_contact'=>'1234-5678910'
    ),
    '1' => array(
        'teachers_name'=>'asd asd asd',
        'teachers_cnic'=>'33434-3434343-4',
        'teachers_gender'=>'2',
        'teachers_contact'=>'2345-6789101'
        ),
    '2' => array(
        'teachers_name'=>'asd asd asd asd',
        'teachers_cnic'=>'34454-5454545-4',
        'teachers_gender'=>'2',
        'teachers_contact'=>'3456-7891011'
    )
);

$this->Teacher->saveMany($data);

见

• Model::saveMany()

Answer 2

您可以像这样创建您的表单字段，您可以将下面的代码放在循环中或其他替代方式中，以便您可以获得 ex:0,1,2 的 $key 变量的动态值， 3,4..等

echo $this->Form->input('modelName.' . $key . '.teachers_name', array());
echo $this->Form->input('modelName.' . $key . '.teachers_cnic', array());
echo $this->Form->input('modelName.' . $key . '.teachers_gender', array());
echo $this->Form->input('modelName.' . $key . '.teachers_contact', array());

提交表单后，您可以像这样在您的控制器中接收表单

$data=array(
    '0' => array(
        'teachers_name'=>'asd asd',
        'teachers_cnic'=>'32312-1212121-2',
        'teachers_gender'=>'1',
        'teachers_contact'=>'1234-5678910'
    ),
    '1' => array(
        'teachers_name'=>'asd asd asd',
        'teachers_cnic'=>'33434-3434343-4',
        'teachers_gender'=>'2',
        'teachers_contact'=>'2345-6789101'
        ),
    '2' => array(
        'teachers_name'=>'asd asd asd asd',
        'teachers_cnic'=>'34454-5454545-4',
        'teachers_gender'=>'2',
        'teachers_contact'=>'3456-7891011'
    )
);

然后就可以保存表单数据了，如下图所示

$this->Teacher->saveMany($data);
