Question

我想让用户添加动态输入并将这些值保存在数据库中。但是使用此代码只有一个值保存到数据库中。如何将所有值保存到用户输入的数据库中这是我添加动态输入的观点

    <script type="text/javascript">
    $(document).ready(function() {
        var max_fields      = 10; //maximum input boxes allowed
        var wrapper         = $(".input_fields_wrap"); //Fields wrapper
        var add_button      = $(".add_field_button"); //Add button ID

        var x = 1; //initlal text box count
        $(add_button).click(function(e){ //on add input button click
            e.preventDefault();
            if(x < max_fields){ //max input box allowed
                x++; //text box increment
                $(wrapper).append('</br><div><input class="input form-control"" name="mytext[]"/><a href="#" class="remove_field">Remove</a></div>'); //add input box
            }
        });

        $(wrapper).on("click",".remove_field", function(e){ //user click on remove text
            e.preventDefault(); $(this).parent('div').remove(); x--;
        })
    });
    </script>
<div class="input_fields_wrap">
                    <div class="form-group">
                    <button type="button" class="btn btn-success add_field_button">Add More Fields</button> 
                    </div>
                    <div>
                    <input class="input form-control" name="mytext[]">
                    </div>
                </div>

这是我的控制器，用于在数据库中保存这些动态输入

function error(){


  if ($this->input->post('mytext')) { 
    $attain = $this->input->post('mytext', true);


    foreach ($attain as $i => $a) { // need index to match other properties
        $data2 = array(
            'mytext' => $a,
            'projectname'                   => $this->input->post('projectname'),

        );

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

}
    }


  }

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,
                'projectname'=> $this->input->post('projectname'),
            );
            //for multiple entry in same table
            $this->db->insert_batch('projectem', $data2); 
            redirect('Select_ctrl2/ModalAddEmployeesProject');
        }
    }
  }

动态输入值不会保存在带有codeigniter的数据库中
