Why does this fail?

[tablex]

Hi,

I was wondering how to pass an integer value (collected from a mysql_fetch_array and is converted to $root_id) in a hyperlink I tried following:

<a href=\"view_topic.php?root_id=$root_id\">...</a>

If I use above with strings everything works fine, but passing an integer value failes everytime...

What am I doing wrong?

Thanks in advance!

It could be the way that its received in the script view_topic.php. Does this expect it to be an integer or a string?

use

<pre>
<?php print_r($HTTP_GET_VARS); ?>
</pre>

to see what is being passed.

I usually like to completely separate text and variables using the concatenation operator, just to be safe.

"link.php?varname=" . $varname . "....";
