                               alert("Thank you for subscribing!");

                               }else if(data.status == 'error'){
                               alert("Error on query!");
                               }
                           },

                            alert("the ajax doesnt work");   
                           }
                   })
                   }
            }
        })
         })
});

login.php中：

  <?php


  $serverName = "AMIN-PC";


  $connectionInfo = array( "Database"=>"Market");
  $conn = new PDO("sqlsrv:Server=AMIN-PC;Database=Market");
  $conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

  $response_array = array();

  if( $conn === false ) {
  die( print_r( sqlsrv_errors(), true));
 }


  $passorg =  $_REQUEST['passorg'];
  $passorg = $conn->quote($passorg); 

  $userorg =  $_REQUEST['userorg'];
  $userorg = $conn->quote($userorg);


   $sql = "select count(*) from customers
    where customers_user=$userorg
    and customers_pass=$passorg";

   $stmt = $conn->query($sql);
   $result = $stmt->fetch();
   $count = $result[0];


  if($count >0) {
  $response_array['status'] = 'success'; 
  }
   else{
  $response_array['status'] = 'error'; 

 }
  header('Content-type: application/json');
 echo json_encode($response_array);
  ?>

HTML：

  <div class="logbut">Login</div>



  <div class="login" style="display:none;">

  <form method="post" class="logform" action="login.php">

  <input type="text" name="userorg" style=" width:80px;" class="userorg" />
  <label>Username</label>


  <input type="password" name="passorg"  style=" width:80px;" class="passorg"/>
  <label>Password</label>

 <input type="submit" style="display:none" value="check"/>
 </form>
 </div>

Answer 1

您可以嘗試在ajax請求中按如下方式指定data參數：

$.ajax({
  url:"login.php",
  type: 'POST',
  dataType:"json",
  data:{passorg:value of passorg},
  success:....

你需要在ajax中傳遞變量並在php中獲取這些變量，例如：

$.ajax({
     url: "your url",
     type: "POST",
     cache: true,
     dataType:'json',
     data: {id: cid},
     success: function(returnedData){
       console.log(returnedData);
     },
     error: function (xhr, tst, err) {
       console.log(err);
     } 
 });

PHP

 $_REQUEST['id'];
