You have to use session for this purpose.As you not posted your code here so i am posting a sample.Let say this is your code.For more help.Check these links.1,2,3.
file1.php
<?php
session_start();
if(isset($_POST['article']))
{
//Then you add here in your MySQL
//Similarly add them in the session so you can access the same data on your file2.php
$_SESSION['article'] = $_POST['article'];
//now redirect to file2.php
}
?>
<form action="#" method="POST">
Article :<input type="text" name="article"/>
<input type="submit" value="click"/>
</form>
file2.php
session_start();
if(isset($_SESSION['article']))
{
echo $_SESSION['article'];
}
