You can do this easily in most languages - in javascript:

var encodedParam = encodeURIComponent('www.foobar.com/?first=1&second=12&third=5');
// encodedParam = 'http%3A%2F%2Fwww.foobar.com%2F%3Ffirst%3D12%26sec%3D25%26position%3D'
(there are equivalent methods in other languages too)

You have to escape the & character. Turn your

&
into

&amp;
and you should be good.


You are missing the ? in the second URL (Also, it should be URL-encoded to be %3F).

Also, I believe that the remaining & need to be URL, not HTML-encoded. Change &second=12&third=5 to %26second=12%26third=5 and everything should just work.

This:

&u=http://www.foobar.com/first=12&amp;sec=25&amp;position=2
should be:

&u=http://www.foobar.com/%3Ffirst=12%26sec=25%26position=2


There's a few errors that I can see.

You can't use $_GET['quantity'] if the user is entering it in without reloading the page (Remember, PHP is not client-side). Thus, I suggest using JavaScript for that.

Javascript:

function buildUrl(a) {
   var qty = document.getElementById("qty").value; 
   a.href = "./shopping-cart.php?part_id="+<?php echo $_GET['part_id']; ?>
   +"&quantity="+qty;
}
As you no longer need to get a PHP variable from the current page, the form is obsolete and a simple link will do.

HTML:

<b>Enter the Quantity you want:</b>
<input type="text" name="quantity">
<a href='#' onclick="buildUrl(this);"> //onclick attribute triggers the JavaScript
    <img src="add_to_shopping_cart.png">
</a>
