Okay here i'm going to show you how to create a simple download counter for your site.
Let's start with admin panel.. it goes like this:
Create this table to your database:
SQL Code:
CREATE TABLE `download` (
`id` INT( 15 ) NOT NULL AUTO_INCREMENT ,
`linkname` VARCHAR( 50 ) NOT NULL ,
`linkurl` VARCHAR( 100 ) NOT NULL ,
`downloads` INT( 15 ) NOT NULL ,
PRIMARY KEY ( `id` )
) ENGINE = InnoDB
connect.php
PHP Code:
<?php
// Let's specify your database's info
$dbhost = "localhost";
$dbuname = "username";
$dbpass = "password";
$database = "database";
//Now let's connect to database
$con = mysql_connect($dbhost, $dbuname, $dbpass);
if(!$con){
die("Can not connect to database: ".mysql_error());
}
//Select your database
$selectdb = mysql_select_db($database, $con);
if(!$selectdb){
die("Can not select a database: ".mysql_error());
}
?>
Later we will incude it in our files.. now let's create your admin panel.
admin.php
PHP Code:
<?php
include("connect.php");
?>

<table width="50%" align="center" border="1">

<?php
// Now let's create our forms and actions
$act = $_GET['act'];
$do = $_GET['do'];
if((!isset($act) || empty($act)) && (!isset($do) || empty($do))){
echo "<br>Choose from menu what you would like to do.<br><br>";
//Create 'add new link' form

//Create a new link
if($do == "addnew"){

if(empty($linkname)){

}
if(isset($linkname) && isset($linkurl)){
$query = mysql_query("INSERT INTO download (linkname, linkurl, downloads) VALUES ('".$linkname."', '".$linkurl."', '0')");
if(!$query){
die("<br>Can not insert your link into database: ".mysql_error()."<br><br>");

// Update your link

if(isset($_REQUEST['submit'])){

."<td>".$lname."</td>"
."<td>".$lurl."</td>"
."<td>".$ldownloads."</td>"
."</tr>";
}
?>
</td>
</tr>
</table>
</body>
</html>
Now let's create a download files file..
download.php
PHP Code:
<?php
include("connect.php");
$id = $_GET['id'];
$query = mysql_query("SELECT * FROM download WHERE id='".$id."'");
$row = mysql_fetch_array($query);
$downloads = $row['downloads'];
$url = $row['linkurl'];
$newcount = $downloads+1;
$update = mysql_query("UPDATE download SET downloads='".$newcount."' WHERE id='".$id."'");
if(!$update){
die("Can not update downloads: ".mysql_error());
}
header("Location: ".$url."");
?>
Now all you have to do is add your download link to database.. then add it's link like this:
www.yoursite.com/download.php?id=1
and then you can view downloads from admin panel
it's so simple..
