transfer data from one page to another

<td><"a href=cart.php?ProductId=$row[ProductId]>Add Item</a></td>

Im trying to get the above code to transfer data from one page to another. I have different items for sale on the page, the information comes from a database and i want it to transfer all the data from a selected item onto the cart page.

I thought the above code would put a link on the page saying Add item, for each item then when i user clicks on the link it will take them to the cart page and i then want it to display the information for the item they selected.

I was also wondering what the code would be that i would put on the cart page to show the result. I want to be able to see three other fields in the database on the cart page aswell.

Look at using sessions.

You can use this method also to transfer product id to cart page

<td><a href="cart.php?ProductId=<?php echo $row[ProductId]; ?>">Add Item</a></td>

Then on cart.php page you can get ProductId using $_REQUEST['ProductId'] variable and further run a database query using this id for other fields from table.

Hi All!

MizzHellz, if you want to implement a useful cart (which you can add 2 or more items), you will need to use sessions (as recommended by aschk).
Additionally you will be passing (HTTP variables) between pages (as recommended by ashish_mat1979).

But I warn you about the security of your application. Don't forget to sanitize all user input, be it taken from forms or urls.

For example, from the code recommended by ashish_mat1979, you should sanitize the ProductID like:
Code:
// Cast the product id to integer.
$prodID = (int)$_REQUEST["ProductID"];
Casting the product id to integer avoids SQL Injection.

Beware of these pontetial threats to your application:
1. SQL Injection
2. Cross Site Scripting (XSS).

If you need more information about (web) application security, please let me know!

Cheers,
Leonel Machava
