passing variables from current url in new href url in HTML code.

[Cosmic Surfer]

I would like to use code to collect variables from a current url like:

http://www.example.com/trythis.php?v...iable&?num=123

I can not find a proper way to get the variable num=123 into an url located in the body of my HTML. For example

<a href="http://www.example.com/promo_board.php ?tid=209&?num=(the desired num variable here)">

[dlite922]

use $_GET.

<?php echo $_GET['num']; ?>

Thanks Dan,

tried it, but don't know how to get the fetched value in the new link address.
How do I get the value in there?

When I use echo I see that it presents the right value as expected, but when clicking the new link, it added just the variable name, instead of the value!
I am directed to a website with url:

http://www.example.com/promo_board.php?tid=209&?num=

Were it misses the 123 value?

Is there some code? How do you generate those links?

You only need one question mark, where you have two:

?var=variable&? num=123

should be

?var=variable&n um=123

get rid of the second one. The reason why It didn't show (i bet) is the 123 value was stored in $_GET['?num'] instead of $_GET['num'];
