Question

通过jQuery / ajax将数据插入数据库后，从数据库中获取值而不刷新页面如何使用codeigniter显示数据库值？

这是我的代码：

脚本：

 <script>
        $(document).ready(function(){
            $("#personal-info").submit(function(e){
               e.preventDefault();
               var suppid = $("#suppid").val();
               var proid = $("#proid").val();
               var custid = $("#custid").val();
                var message = $("#message").val();

                $.ajax({
                    type: "POST",
                    url: "<?php echo base_url(); ?>index.php/Profile_cntrl/buyer_communication",
                    data: {suppid:suppid,proid:proid,custid:custid,message:message},
                    success:function(data)
                    {
                        alert('SUCCESS!!');
                    },
                    error:function()
                    {
                        alert('fail');
                    }
                });
            });
        });
    </script>

控制器：

public function buyer_communication() {

        $result1 = $this->Profile_model->fetch_Data($product_id);


        $Userid = $this->session->userdata('id');
        $result3 = $this->session->userdata('tt');
        $data4 = array(
            'message' => $this->input->post('message'),
            'supplier_id' => $this->input->post('suppid'),
            'product_id' => $this->input->post('proid'),
            'Customer_id' => $this->input->post('custid'),
            'From' => $result3,
        );

        $this->Profile_model->buyer_insert($data4);

        redirect('welcome/buyermessageview?id=' . $product_id);
    }

型号：

function buyer_insert($data4) {
        $this->db->insert('communication', $data4);
        return ($this->db->affected_rows() != 1) ? false : true;
    }

形式：

<form class="form-horizontal" method="POST" id="personal-info"  role="form" action="#"> 
                            <div class="panel-footer">
                                <div class="input-group">

                                    <input type ="hidden" name="suppid" id="suppid" value="<?php echo $row->supplier_id; ?>" class="form-control" />
                                    <input type ="hidden" name="proid" id="proid" value="<?php echo $row->product_id; ?>" class="form-control" />
                                    <input type ="hidden" name="custid" id="custid" value="<?php echo $row->Customer_id; ?>" class="form-control" />



                                    <input id="message" name="message" type="text" class="form-control input-sm chat_input" placeholder="Write your message here..." />
                                    <span class="input-group-btn">
                                        <button class="btn btn-primary btn-sm" id="submit-p" name="submit-p">Send</button>
                                        <!--<input type="submit" name="submit-p" id="submit-p" value="send" class="btn btn-primary btn-sm" >-->
                                    </span>
                                </div>
                            </div>
                        </form>
