大家好，我在'where子句'中不断得到一个未知列'Array' $receiverName，当我调试时$receiver我得到这个输出

array(
    (int) 0 => array(
        'Invoice' => array(
            'receiver_id' => '3',
            'id' => '1'
        ),
        'FieldsInvoice' => array(
            (int) 0 => array(
                'id' => '1',
                'field_id' => '9',
                'invoice_id' => '1',
                'entered_value' => '1000.00'
            )
        )
    ),
    (int) 1 => array(
        'Invoice' => array(
            'receiver_id' => '4',
            'id' => '2'
        ),
        'FieldsInvoice' => array(
            (int) 0 => array(
                'id' => '2',
                'field_id' => '9',
                'invoice_id' => '2',
                'entered_value' => '2000.00'
            )
        )
    ),
    (int) 2 => array(
        'Invoice' => array(
            'receiver_id' => '7',
            'id' => '3'
        ),
        'FieldsInvoice' => array()
    ),
    (int) 3 => array(
        'Invoice' => array(
            'receiver_id' => '8',
            'id' => '4'
        ),
        'FieldsInvoice' => array()
    ),

    //returns receiver_id from the invoices table where sender_id=current user account

$receiver=$this->Invoice->find('all',array(
        'fields'=>('receiver_id'),'conditions'=>array(
        'sender_id'=>$accounts2)));

    //returns company_name from the accounts tables where receiver_id=account.id

我想要做的是receiver_id从数组中抓取，然后将其与account.id然后打印进行比较，但它与我的findcompany_name中的 where 语句引发了问题$receiverName

$receiverName=$this->Account->find('all',array(
        'fields'=>('company_name'),'conditions'=>array(
        'id'=>$receiver)));

那是因为您正在传递数组，请将您的 $receiver 行更改为以下

$receiver=$this->Invoice->field('receiver_id',array('sender_id'=>$accounts2));

1) 下载并安装DebugKit（这是任何 CakePHP 项目的必备 - 认真）

2）点击右上角的DebugKit图标展开它的选项

3）点击“Sqllog”选项卡，看看它在哪里显示“Array”而不是你想要的值

4）将值更改为不是数组

5）给自己买一个冰淇淋或啤酒或其他什么，然后休息一晚，因为你的查询现在有效。

PS-也根据评论，应该是'fields'=>array('company_name')，不是'fields'=>('company_name')
