如何在表单提交上刷新php页面？ [重复]

My issue is after submitting the form element in a php page, the page does not refresh. Here is my code.

<?php
    session_start();
    include('db.php');
    include('pages.php');
?>

form element

<form action = "<?php echo $_SERVER['PHP_SELF'];?>" method = "POST">
   <table style="width:70%">
      <tr>
         <td width="10%">First Name</td>
         <td width="20%"><input style="border-radius: 4px; border: 2px solid gray; height: 20px; width: 180px;" type="text" name="fname" value="<?php echo $f_name;?>"></td>
      </tr>

<input style="border-radius: 5px; width: 100px; height: 25px;" type="submit" name="account_update" value="Update"/></td>
   </table>
</form>

if(isset($_POST['account_update']) && $_POST['account_update'] == 'Update'){

    $fname_edit = $_POST['fname'];

    $sql = $db->prepare("SELECT * from table where email = ?");
    $sql->bind_param("s",$email);
    $sql->execute();
    $sql = $sql->get_result();
    if(($getRowCount = $sql->num_rows) == 1){
    $updateQuery = $db->prepare("UPDATE info set first_name=? where email = ?");
                                       $updateQuery->bind_param("ss",$fname_edit,$email);
    $updateQuery->execute();
       }        
    }

 ?>

So clicking on update, inserts the data in the tale, but it only shows up on the page when I refresh it for a second time.

Also. pages.php is another page being fetched by including. My current page gets refreshed fine if I remove the include('pages.php'), but not with it. Any suggestions on how to get this thing out this would be of great help.

You may redirect user to current file. After:

$updateQuery->execute();

Add:

header("Location: yourfile.php");
//header("Location: ".basename(__FILE__, '.php')); Might work too

This will redirect user to this file after executing query.

// REFRESH PAGE
echo "<meta http-equiv='refresh' content='0'>";
