php - jQuery GET overwiting POST -

i've got simple jquery script isn't behaving correctly. doing wrong? idea user enters value textbox , clicks button. jquery uses post send value php file. php file runs simple sql query , gives response. jquery .load used refresh div containing original php.

using chrome's tools, i've noticed response post perfect. however, gets overwritten no data.

jquery:

$("#gotest").click(function() { var customer = $("#customer").val(); if (customer == '') {   $('#alert_formula_save_failed').show(); } else {   $.post("../assets/forms/formulations/set_session.php", {     customer: customer,      }, function(data) {       $('#alert_formula_save_success').show();       $('#dynamic').load('../assets/forms/formulations/set_session.php');       $('#alert_formula_save_failed').hide();       settimeout(function() { $('#alert_formula_save_success').fadeout('fast'); }, 3000);   }); } }); 

php:

 <?php     $customer = null; $customer = 'test' ; $customer2 = $_post['customer'] ;  .. db connection bits ;  try  {     $pdo =  new pdo( "mysql:host=".$host.";"."dbname=".$dbname, $user, $pass);   } catch(pdoexception $e)  {     die($e->getmessage());   }     $pdo->setattribute(pdo::attr_errmode, pdo::errmode_exception);     $sql = "select * db_customers customer = '$customer' ";     $stmt = $pdo->prepare($sql);     $stmt->execute(array($id));     $data = $stmt->fetch(pdo::fetch_assoc);     $pdo = null;      $iscurrent  = $data['iscurrent'];      echo '<br>' ;     echo 'response 1-' ;     echo $iscurrent;     echo '<br>' ;     echo 'response 2-' ;     echo $customer2 ;  ?> 

html:

<form id="testform" name="testform" method="post">      <button type="button" name="gotest" id="gotest" class="btn btn-info">         <i class="fa fa-frown-o"></i>          set session     </button> 

the idea being 'response 1' echoes predefined value. response 2 should echo out whatever typed text input box.. overwrites everything.

the "issue" line:

$('#dynamic').load('../assets/forms/formulations/set_session.php'); 

it uses default.

try using in place:

$('#dynamic').html(data);
