simple while statement/query not working
 
PHP Code:
$links = $db->query_first("SELECT pl_href AS href, pl_title AS title, pl_anchor AS anchor FROM " . TABLE_PREFIX . "user WHERE pl_href != ''");
while ($link = $db->fetch_array($links)) eval('$premium_links = "' . fetch_template('directory_premium_links') . '";'); 
I've added the three fields you see above to the user table so I can print out a list of websites on a certain page. However, when I use query_first it doesn't print anythign out. When I use query_read it only prints out the last link that would show (because read is not an array function). Why doesn't it work with first?

TRY:
PHP Code:
$links = $db->query("SELECT pl_href AS href, pl_title AS title, pl_anchor AS anchor FROM " . TABLE_PREFIX . "user WHERE pl_href != ''");
while ($link = $db->fetch_array($links))
{
    eval('$premium_links .= "' . fetch_template('directory_premium_links') . '";');
}

To print all when using query_read(), change the eval statement to:
PHP Code:
eval('$premium_links .= "' . fetch_template('directory_premium_links')

Because you don't need the while-statement or the fetch_array() if you're using query_first. query_first will already restrieve the row (query_first never return more then 1 row). With query_first you would need just (asuming your query would never return more then 1 row:
PHP Code:
 $link = $db->query_first("SELECT pl_href AS href, pl_title AS title, pl_anchor AS anchor FROM " . TABLE_PREFIX . "user WHERE pl_href != ''"); 
eval('$premium_links = "' . fetch_template('directory_premium_links') . '";');

'query' is depreciated in vB3.5, use query_read or query_write instead.
