The $_GET variable

[buddhi225]

I am trying to get values from firstpage.php and send them to secondpage.php this is what i have figured out and i am wondering if it is the correct way to do it thanks.

Firstpage.php

 <?php
//Connects to the database.
$con = mysql_connect("localhost","blank","blank") or die (mysql_error());
$db = mysql_select_db("wsdatabase") or die (mysql_error());
// Selects username's from the user table.
$sql = "select username from users";
$query = mysql_query($sql);
// List's every name in the table with a link going to the secondpage.php.
while($row = mysql_fetch_array($query)) {
    printf("<a href='secondpage.php?username=%s'>%s</a>"."<br/>",$row['username'],$row['username']);
}
?>

secondpage.php

 <?php
// Grabs the username with the get method.
if(isset($_GET['username'])) {
    $username = $_GET['username'];
}
// Connects to the database.
$con = mysql_connect("localhost","blank","blank") or die (mysql_error());
$db = mysql_select_db("wsdatabase") or die (mysql_error());
// Selects everything from the database.
$sql = "select * from users where username = '$username' ";
$query = mysql_query($sql);
// Prints everything out from the database.
while($row = mysql_fetch_array($query)) {
    echo "<b>".$row['title']."</b>";
    echo "<br/>";
    echo "<b>".$row['username']."</b>";
    echo "<br/>";
    echo "<b>".$row['email']."</b>";
}
?>

I think it work ok, but in my opinion this is not really a good way.
If i were you, I will use POST method to avoid posting variable to address
Btw, you should print some thing when there is no username match $_GET['username'], kind da like: User name ABC not found or st :)
