Is it possible to POST values to next page with a Drupal URL?
To prepare links in Drupal, use the l() function:

$options = array('query' =&gt; array('orange_id' =&gt; $row['orange_id']));
$link = l('Edit', 'node/17', $options);


You can also add 'absolute' =&gt; TRUE to your options array to get the full URL; full options are on the docs page.

Using l() you can ensure that your URL is valid at all times.
