Question

我想在 $ achie = $ this-＆gt; input-＆gt; post（＆＃39; mytext＆＃39;，true）一行中删除输入＆gt;帖子 ; 。用多种方式测试，但显示错误。我该怎样摆脱这个帖子的方法？

$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); 

        //}
    }

这是我用户生成动态输入的视图

    </script>
    <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>

这是3values在数据库中保存的方式

从您上面的评论我认为您的麻烦是相同的数据插入多次。如果是这种情况，

我想你错过了一个结束括号。在循环外试试$this->db->insert_batch('projectem', $data2);

$attain = $this->input->post('mytext', true);
$data2 = array(); //<-initialize

foreach($attain as $i => $a)
{  
    $data2[] = array(
      'mytext' => $a,
      'projectname' => $this->input->post('projectname') ,
    );

}  // modification here

 /*
  * if the insert_batch is inside the loop, insert will
  * occur multiple times with
  */ 

  $this->db->insert_batch('projectem', $data2);

删除post方法并初始化php codeigniter中的每个循环
