Без обновления страницы, как отображать значения из базы данных с помощью ajax / jQuery

После вставки данных в базу данных через jQuery / ajax при извлечении значений из базы данных без обновления страницы, как отображать значения базы данных с помощью codeigniter?

форма отображения

Это мой код:

Автор сценария:

<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> 

контроллер:

 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); } 

Модель:

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

Форма:

 <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>
