Secure Random Adoption Process

[fadillzzz]

This mod is intended for people who already or wanted to have a random adoption process on their adoptables site.
This mod will use Session Value instead of the GET method to transfer the id of an adoptables from adopt.php to doadopt.php
That way people won't be able to manipulate the id of an adoptables to another id to get the adoptables they want.
You can use POST method but they can change it using the text editor. So with this mod, they have no idea how to do that.

NOTE:Please make a backup of your files before installing this mod!

Now, let's move on!
1. Open your adopt.php file, on line 2 just below the

PHP Code:

<?php

tag put this code

PHP Code:

session_start(); // This is important! 


2.(Skip this step if your site already limit the adopt.php to only show 1 random adoptables)
Go to line 86, replace this code

PHP Code:

$query = "SELECT * FROM ".$prefix."adoptables"; 


with this

PHP Code:

$query = "SELECT * FROM ".$prefix."adoptables WHERE whenisavail = 'always' ORDER BY RAND() LIMIT 1"; // Only shows 1 random adoptables 


3. Put this code on line 98

PHP Code:

$_SESSION['id'] = $aid; // This is what we use to transfer the aid value 


4. Then on line 119 find this code

PHP Code:

    $article_content = $article_content."<p><b><a href='adopt.php?id=".$aid."'><img src='templates/icons/add.gif' border=0> Adopt ".$type."</a></b></p>"; 


And replace it with this

PHP Code:

$article_content = $article_content."<br><img src='".$eggimage."' border='0'><br>
<form name='form1' method='get' action='doadopt.php'>
  <p>Adoptable Name: 
    <input name='name' type='text' id='name'>
    <input name='promocode' type='hidden' id='promocode' value='".$promocode."'>
  </p>
  <p>
    <input type='submit' name='Submit' value='Adopt Me'>
</p>
</form>"; 


5. After that, remove these 2 lines from the file (line 115 & 116)

PHP Code:

$article_content = $article_content."<p><b><u><a href='adopt.php?id=".$aid."'>".$type.":</a></u></b></p>
<p><a href='adopt.php?id=".$aid."'><img src='".$eggimage."' border='0'></a></p>"; 


We're done with adopt.php, let's continue with editing doadopt.php
1. Open your doadopt.php, on line 2 just below the

PHP Code:

<?php

tag put this code

PHP Code:

session_start(); // This is important! 


2. Find this code on line 65 -75

PHP Code:

$id = $_GET["id"]; 


And replace it with

PHP Code:

if($_GET["id"] == ""){
$id = $_SESSION['id'];
}elseif($_GET["id"] != ""){
$id = $_GET["id"];
} 


3. Find this code

PHP Code:

if($isloggedin == "yes"){ 


And before that line add this

PHP Code:

if($promocode != ""){ 


4. And then before this

PHP Code:

// **********************************************************************
// Begin Template Definition
// ********************************************************************** 


Add this code

PHP Code:

}else{
$article_title = $accden;
$acticle_content = "Enter error message here";
} 


NOTE:Don't forget to edit the "Enter error message here" text



That's it you're done! Now people will completely get unchangeable random adoptables!
