What is wrong with this?

PHP Code:


		
			
$prevpagenumber=$pages[pagenumber]-1;

$nextpagenumber=$pages[pagenumber]+1;

$prevquery=$DB_site->query("SELECT pageid FROM highlightpages WHERE pagenumber=$prevpagenumber && highlightid=$pages[highlightid]");

$nextquery=$DB_site->query("SELECT pageid FROM highlightpages WHERE pagenumber=$nextpagenumber && highlightid=$pages[highlightid]");

$prevpageid=$prevquery[pageid];

$nextpageid=$nextquery[pageid];



if ($prevquery!=0) {

$prevpage = "<a href='content.php?s=&action=highlight&do=page&pageid=$prevpageid'>Previous Page</a> | ";

}



if ($nextquery!=0) {

$nextpage = "<a href='content.php?s=&action=highlight&do=page&pageid=$nextpageid'>Next Page</a>";

}

It isn't finding anything, even if something exists. Yet, it still shows the links, which are dead links at that. Help?

you cant user query here, you have to use query_first:

PHP Code:


		
			
$prevpagenumber=$pages[pagenumber]-1;

$nextpagenumber=$pages[pagenumber]+1;

$prevquery=$DB_site->query_first("SELECT pageid FROM highlightpages WHERE pagenumber=$prevpagenumber && highlightid=$pages[highlightid]");

$nextquery=$DB_site->query_first("SELECT pageid FROM highlightpages WHERE pagenumber=$nextpagenumber && highlightid=$pages[highlightid]");

$prevpageid=$prevquery[pageid];

$nextpageid=$nextquery[pageid];



if ($prevquery!=0) {

$prevpage = "<a href='content.php?s=&action=highlight&do=page&pageid=$prevpageid'>Previous Page</a> | ";

}



if ($nextquery!=0) {

$nextpage = "<a href='content.php?s=&action=highlight&do=page&pageid=$nextpageid'>Next Page</a>";

}

If I knew it'd be a stupid mistake like that, wow.... lol ;)

Thanks :)
