Can you replace your thankstudent.php with this one.
<?php
require_once('connect_login.php');
$title = $_POST['title'];
$description = $_POST['description'];
$std_name = $_POST['std_name'];
$total_pages = $_POST['total_pages'];


$sql = "INSERT INTO `text`.`developer` (`id` ,`title` ,`description` ,`year` ,`std_name` ,`total pages` )VALUES ('', '$title', '$description', '', '$std_name', '$total_pages');";
echo $sql;
echo "<br>";
mysql_query($sql) or die(mysql_error());
echo "Done";

?>
