php - 错误 : Unknown column 'Array' in 'field list' (codeigniter)

Question

我收到这个错误

Unknown column 'Array' in 'field list'

将复选框列表插入数据库时​​。当我执行 print_array 时，我得到了这个结果:

Array
(
    [0] => Array
        (
            [user_id] => 3
            [project_id] => 10
            [project_type] => 5
            [project_list] => Array
                (
                    [0] => 17
                    [1] => 18
                )

        )

)

project_list应该将值插入数据库中的新行。

我的看法:<input type="checkbox" value="<?php echo $project_list['id']; ?>" name="project_list[]">这是从数据库中填充的。

我的 Controller :$this->Project_module->createProject($_POST['project_list']);

我的模块

public function createProject($project_list){

    if($project_list != null){

        $data = array();

        foreach($project_list as $project_list){
            $data[] = array(
                'user_id'          => $this->getUserId(),
                'project_id'       => $this->getProjectId(),
                'project_type'     => $this->getProjectType(),
                'project_list'     => $this->getProjectList(),
            );
        }

        $this->db->insert_batch('tblProject', $data);

        if($this->db->affected_rows()){
            return true;
        } else {
            return false;
        }

    } 

}

编辑 我是这样编辑我的foreach的

foreach($project_list as $row){
    $data = array(
        'user_id'          => $this->getUserId(),
        'project_id'       => $this->getProjectId(),
        'project_type'     => $this->getProjectType(),
        'project_list'     => $this->getProjectList(),
    );
}

但我仍然遇到同样的错误。

Linundus，您需要将 foreach 中的数组别名命名为不同的名称。你有

foreach ($project_list as $project_list)

你需要有这样的东西:

foreach($project_list as $list)
