Javascript或Jquery并发布到php

Question

I want to send a javascript variable to a php file. What I would like to know is could you do it via this method?

Jquery:

Var UserName;
UserName = John;
$.post("InsertRunInfo.php", { UserName: UserName } );

Pass to php:

<?php
$con = mysql_connect("*****","*****","");
if (!$con)
  {
  die('Could not connect: ' . mysql_error());
  }

mysql_select_db("runtracker", $con);


$sql="INSERT INTO userinfo (UserName)
VALUES
('$_POST[UserName]')";

if (!mysql_query($sql,$con))
  {
  die('Error: ' . mysql_error());
  }
echo "1 record added";

mysql_close($con);
?>

Answer 1

You can use Jquery .load(), if you want to post data to your php file, and your message"1 record added" will be loaded on same page from which you posted the data.

       <script type='text/javascript'>
         $('#formid').submit(function(){
               $('#message_div').load("processinfo.php",UserName:$('#username_input_box_id').val()})     
       });
       </script>
      <?php
       //your processinfo.php can retrieve the posted data

       $var = new secure();
       $usernam = $var->secureSuperGlobalPOST('UserName');

        //your rest of code
     ?>
