Adding variables to URL

[geenee]

Ok, there may well be a very simple solution to this problem but I can't think of it so here it is..

 

I've got several pages on a web site, the first is the index.php the others are index.php?type=1, index.php?type=2 etc... each page lists items and when you click on an item it displays the item's info, the link(s) to display the item's info should be:

 

<a href='{$PHP_SELF}&pid={$row[pid]}'>Item Link</a>

 

this works fine on all the pages apart from index.php, as the link comes out as:

 

index.php&pid=1

 

whereas it should be

 

index.php?pid=1

 

What is the simplist way for the script to use ? instead of & if there is no variable already being send through the URL??

 

Thanks

Do:

$sep = ( isset($_GET) && (count($_GET) > 1) ) ? '&' : '?';

echo '<a href="' . $_SERVER['PHP_SELF'] . $sep . 'pid=' . $row['pid'] . '">Item Link</a>';
