Important!!  A way to prevent people stealing shop adoptables![/size]
Open adopt.php and find something like this in the code (it won't be exactly like mine):
	PHP Code:
	
		
			
if($newID != $aID){
$stop = 1;
$article_title = "Oops";
$article_date = date('Y-m-d');
$article_content = "This Digimon is not available for adoption.";
} 
		
	
 below it, insert this:
	PHP Code:
	
		
			
if($memberlevel != free){
$stop = 1;
$article_content = "You cannot adopt this pet for free!.";
} 
		
	
 
[size=large]Earning money on level up
[/size]
Step 1:  Run this here MySQL query to add the money field in your users table:
	PHP Code:
	
		
			
ALTER TABLE users
ADD money INT(11) NULL DEFAULT '0' 
		
	
 Step 2: This is where the magic happens.
Download levelup.php and edit it to suit your site. Replace the number 10 with your desired amount of currency per level up.
Step 3: This is important if you still want people to be able to register. :P
Edit register2.php and find this line: 
	PHP Code:
	
		
			
mysql_query("INSERT INTO users VALUES ('', '$username', '$pass1','$email','free',)"); 
		
	
 Replace it with:
	PHP Code:
	
		
			
mysql_query("INSERT INTO users VALUES ('', '$username', '$pass1','$email','free','0')"); 
		
	
 [size=large]Show the total amount of money to your users[/size]
Add this....
	PHP Code:
	
		
			
if ($isloggedin == "yes"){
$query = "SELECT * FROM `users` WHERE `username` = '".$luser."'";
$result = mysql_query($query);
$num = mysql_numrows($result);
$i=0;
    while ($i < 1) {
    
    $money =@mysql_result($result,$i,"money");
    $i++;
            }
$template = replace(':WELCOMEORREGISTER:','',$template);
$template = replace(':LOGINORACCT:', '<p>Hi, '.$username.'
<p>Currency name: '.$money.'
<p><a href="logout.php">Log out</a>' ,$template); 
		
	
 In between ...
	PHP Code:
	
		
			
//$isloggedin = "no"; 
		
	
 and...
	PHP Code:
	
		
			
}
else{
//User is not logged in 
		
	
 On 
all of your pages.

Shop to buy adoptables[/size]
Step 1:
Download shop.php, buy.php, and buyconfirm.php and upload them to your main folder.
Step 2:
Add adoptables for sale by running a query like this.  Do not change the shop part unless you know what you're doing.
	PHP Code:
	
		
			
INSERT INTO adoptables VALUES ('', 'name','level 0 image','shop','cost') 
		
	
 Then add the rank images, too.  Put the image urls in place of the numbers.  1 will have its level 1 image, 2 the level 2 image, etc.
	PHP Code:
	
		
			
INSERT INTO adoptable_rankimages VALUES ('name','1','2','3','4','5','6','7','8')
