hello all, 
as promised, my houses modification, still far from perfect, but it works pretty good already~
i hope you'll get the idea of how to apply/extend this mod.
i'm also glad to hear any update you've made of this~
instructions provided in the board aswell the zip file~
please don't shoot me if i did something wrong, i'm a human and i do make mistakes, so please back-up your adoptables site before you start~!
THIS IS FOR V1.3.1, for v1.3.2, see the end of this post!
 
(It works for me though.. :3c)
instructions below:
insert into the users table a new column: 
	Code:
	houses int(11) default 1
 __________________________________________________  _________________________________________
copy functions_houses into your functions folder
in the main functions file, find:
	PHP Code:
	
		
			
    $GLOBALS['isloggedin'] = $isloggedin;
    $GLOBALS['username'] = $username;
    $GLOBALS['loggedinname'] = $username;
    $GLOBALS['money'] = $GLOBALS['usersettings']['money'];
    $GLOBALS['group'] = $usergroup; 
		
	
 and add this underneath it:
	PHP Code:
	
		
			
    $GLOBALS['houses'] = $houses; 
		
	
 find: 
	PHP Code:
	
		
			
        $luid=$GLOBALS['usersettings']['uid'];
        $lsess=$GLOBALS['usersettings']['session'];
        $usergroup=$GLOBALS['usersettings']['usergroup']; 
		
	
 and add this line underneath them:
	PHP Code:
	
		
			
        $houses=$GLOBALS['usersettings']['houses']; 
		
	
 __________________________________________________  _________________________________________
next, edit adopt.php:
include this line at the beginning:
	PHP Code:
	
		
			
include("functions/functions_houses.php"); 
		
	
 find:
	PHP Code:
	
		
			
    // Begin the output of all the adoptables to the user...
    $stmt = $adopts->join("adoptables_conditions", "adoptables_conditions.id = adoptables.id")
    ->select("adoptables", array()); 
		
	
 put this under it:
	PHP Code:
	
		
			
if ($freespace > 0) { 
		
	
 and put before:
} // This bracket ends the else statements for whether or not an ID was entered
	PHP Code:
	
		
			
this:
}}else { 
$article_content .= "You don't have enough free space in your houses left anymore, you need to buy new houses for your new adopts!"; 
		
	
 __________________________________________________  _____________
breeding.php:
add:
	PHP Code:
	
		
			
  include("functions/functions_houses.php"); 
		
	
 on top
find:
	PHP Code:
	
		
			
if($isloggedin == "yes" and $userstatus['canbreed'] == "yes"){ 
		
	
 and add underneath it:
	PHP Code:
	
		
			
if ($freespace > 0) { 
		
	
 find: 
	PHP Code:
	
		
			
}// this is the end of if($isloggedin == "yes") 
		
	
 and add this above it:
	PHP Code:
	
		
			
}else { 
$article_content .= "You don't have enough free space in your houses left anymore, you need to buy new houses for your new adopts!";

add as usual in the beginning:

 and find:
	PHP Code:
	
		
			
if($isloggedin == "yes"){ 
		
	
 add underneath it:

$article_content = "Trading is either not enabled or not currently available for your site.";
}
}

 add this under it:

else {
$article_content .= "You don't have enough free space in your houses left anymore, you need to buy new houses for your new adopts!";

 __________________________________________________  _________________________________________

 this:
    
	PHP Code:

Next, copy the houses.php file into the main directory, and make a link to it in the admin panel.
optional, you can edit functions.php again, and add this to the function getsidebar (if you haven't done so already):
before the logout.php link:
	PHP Code:
	
		
			
$wpath = $GLOBALS['houses'];
$housing = $wpath;
$sidebar .= "<li><a href='houses.php'>You have {$housing} house(s)</a></li>"; 
		
	
 optional, you can edit the variables in functions_houses.php 
	PHP Code:
	
		
			
($req_monforhouse, $maximumhouses, $spots) 
		
	
  to your desires~ :3c
This works with MYS 1.3.1
now the updated version for V1.3.2 :
simple houses system (workaround for the OOP php of mysidia, i hope this also works for people who don't know OOP php programming ;3)
edit functions_houses.php variables to your desires.
place functions_houses into your functions folder
in inc/init.php, add this just before the end:
	PHP Code:
	
		
			
$function_houses = "{$dir}functions/functions_houses.php";
include($function_houses); 
		
	
 adopt.php:
find:
