这显示了什么：echo $this->CustomerProblems->find()->where($delete)->sql();

标签： php mysql sql cakephp-3.0

【解决方案1】：

        $delete = $this->CustomerProblems->find()->where([

            'problem' => $search['problem'],
            'resolve_status' => $search['resolve_status'],
            'status' => $search['status']
        ]);
        $flag = 0;
        // pr($delete->toArray());die;
        foreach ($delete as $key) {
            $this->CustomerProblems->delete($key);
            $flag = 1;
        }
        if($flag == 1){

【解决方案2】：

deleteAll 不需要删除实体列表，它需要一组条件并删除匹配的所有内容。

if($this->CustomerProblems->deleteAll([
    'customer_id' => $search['customer_id'],
    'mobile_no' => $search['mobile_no'],
    'order_no' => $search['order_no'],
    'problem' => $search['problem'],
    'resolve_status' => $search['resolve_status'],
    'status' => $search['status']
])) {

请注意，它返回受影响的行数，而不是真/假，因此您的 if 逻辑可能需要稍作更改才能考虑到这一点。
