javascript - session not being passed to process.php -

i have looked @ similar questions none seems answer looking for. validation script doesnt recognise input fields - session not being passed.

code follows:

var data = {}; $(document).ready(function() { $('input[type="submit"]').on('click', function() {     reseterrors();     var url = 'process.php';     $.each($('form input, form select'), function(i, v) {         if (v.type !== 'submit') {             data[v.name] = v.value;         }     }); //end each     $.ajax({         datatype: 'json',         type: 'post',         url: url,         data: data,         success: function(resp) {             if (resp === true) {                     //successful validation                     $('form').submit();                     return false;             } else {                  $.each(resp, function(i, v) {             console.log(i + " => " + v); // view in console error messages                      var msg = '<label class="error" for="'+i+'">'+v+'</label>';                     $('input[name="' + + '"], select[name="' + + '"]').addclass('inputtxterror').after(msg);                 });                 var keys = object.keys(resp);                 $('input[name="'+keys[0]+'"]').focus();             }             return false;         },         error: function() {             console.log('there problem checking fields');         }     });     return false; }); }); function reseterrors() { $('form input, form select').removeclass('inputtxterror'); $('label.error').remove(); } 

html form:

<form  action="process.php" method="post" > <label>first name</label>  <input name="first_name" type="text"  /> <label>email</label>  <input name="email" type="text"  /> <input type="submit" value="submit" />  </form> session_start() @ top of page. 

process.php code:

session_start(); if(isset($_post)){ if (empty($_post['first_name'])) {     $_session['errors']['first_name'] = 'name missing';          } if (empty($_post['email'])) {     $_session['errors']['email'] = 'mail missing';          }      if(count($_session['errors']) > 0){     //this ajax requests:         if(!empty($_server['http_x_requested_with']) &&  strtolower($_server['http_x_requested_with']) == 'xmlhttprequest') {             echo json_encode($_session['errors']);             exit;          }     //this when javascript turned off:        echo '<ul>';         foreach($_session['errors'] $key => $value){       echo '<li>' . $value . '</li>';        }        echo '</ul>';exit; }else{ //form validation successful - process data here!!!!   } } 

i new ajax (as can see) appreciated.

you have set array session,

if(isset($_post)){   $_session['errors'] = array();     if(empty($post['first_name']))     {         $_session['errors'][] = "first name cannot blank.";     }       ....  }
