Question

开发以下代码以使用codeigniter框架在数据库中保存4个动态输入数据。但由于错误，第一个输入框的值仅保存了4次。我已经包含了代码和屏幕截图。有人可以帮我纠正这个问题吗？这是我向数据库输入值的方式

但这是它在数据库中保存的方式

这是我的控制器

function error(){
    //if ($this->input->post('mytext')) {

       $attain = $this->input->post('mytext', true);
        $data2=array(); //<-initialize
            foreach ($attain as $i => $a) { // need index to match other properties
                //append array
                $data2[] = array(
                'mytext' => $a,
                'mytext1' => $a,
                'mytext2' => $a,
                'mytext3' => $a,
                'projectname'=> $this->input->post('projectname'),
            );
            //for multiple entry in same table


        //}
    }
    $this->db->insert_batch('projectem', $data2); 
    redirect('Select_ctrl2/ModalAddEmployeesProject');
  }

这是我的观点

您正在覆盖该foreach上的每次迭代中的值，请记住您将mytext，mytext1，mytext2和mytext3作为数组接收，因此您需要通过其索引访问每个值：

function error(){
       $attain = $this->input->post();
       $data2=array(); //<-initialize
       for ($i = 0; $i < count($attain['mytext']); $i++) {
                //append array
                $data2[] = array(
                    'mytext' => $attain['mytext'][$i],
                    'mytext1' => $attain['mytext1'][$i],
                    'mytext2' => $attain['mytext2'][$i],
                    'mytext3' => $attain['mytext3'][$i],
                    'projectname'=> $attain['projectname'],
                );
                //for multiple entry in same table
       }
    $this->db->insert_batch('projectem', $data2); 
    redirect('Select_ctrl2/ModalAddEmployeesProject');
  }

使用codeigniter，动态输入值无法正确保存在数据库中
