I am designing a real estate website. I have many ads in my website and thanks to my friend Arsh Singh I create a 'favorite' or 'save' button on each of the posts that will save the selected page title in a certain page based on cookies for user to review the post when ever he or she wants.
Now i want to send ad's id to the favorite page when user click on "add to favorites" thus based on id i can fetch that certain ad data from database .
can i do this? how? this is my current code and it can only send page title to the favorite page. any idea?
<!DOCTYPE html>
<html>
<head>
<title>New page name</title>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.2.2/jquery.min.js"></script>
<script src=favoritecookie.js></script>
</head>
<body>
<a href="javascript:void(0);" id="addTofav">Add me to fav</a>
<ul id="appendfavs">
</ul>
<?php
error_reporting(0);
include("config.php");
(is_numeric($_GET['ID'])) ? $ID = $_GET['ID'] : $ID = 1;
$result = mysqli_query($connect,"SELECT*FROM ".$db_table." WHERE idhome = $ID");
?>
<?php while($row = mysqli_fetch_array($result)):
$price=$row['price'];
$rent=$row['rent'];
$room=$row['room'];
$date=$row['date'];
?>
<?php
echo"price";
echo"room";
echo"date";
?>
<?php endwhile;?>
</body>

$myVariable = "Some text"; And the form's action for that page is "Page2. php".
You can set URL param values in two ways. Simpler way to do it is by adding it to the link which is fine when you have static values. But in case of variables your only option is JavaScript. And then all you have to do on the second page is just read the values from the URL params.
JSON in Cookie You can use JSON to store the details (id, post name, etc) into a cookie by serialising the JSON: jquery save json data object in cookie
However you should not store database table names in cookies for security's sake.

I would use pure PHP... setcookie() to place a cookie, and read it back when needed using PHP $_COOKIE. Since there would be a need to store a lot of data, structured, related or not, I would then create an associative array, fill it accordingly and then use PHP serialize() it before save it in a cookie; unserialize() when reading:
Saving:
a) $data = array("ID"=>value, "otherdata"=>value...etc);
b) $dataPacked = serialize($data);
c) setcookie("cookieName", $dataPacked);
Reading:
a) $dataPacked = $_COOKIE["cookieName"];
b) $data = unserialize($dataPacked);
Then use $data array as needed. If I would need some Javascript with that data I would simply do:
<script>
var jsVar = "<?php echo $data['key'];?>";
Or go fancier with loops to write more vars from $data, etc.
