mysql_fetch_array() error

ok i am getting an error after having this query on my index

this is the error

Code:

Warning: mysql_fetch_array(): supplied argument is not a valid MySQL result resource in /forums/admin/db_mysql.php on line 154

this is the query

Code:

$newestsql=$DB_site->query("SELECT * FROM gal_Object where Freigabe='y' order by newat desc limit 1"); 

while($newObject=$DB_site->fetch_array($newestsql)) {

$getnewthumb=$DB_site->query_first("SELECT * FROM gal_Pictures where Object='$newObject[ID]' ORDER BY rand() DESC LIMIT 1");

 // get a random pic

        $tmpnew=explode(".",$getnewthumb[filename]); 

        $newthumbfilename="gt_".$tmpnew[0].".jpg";

eval( '$newestsql = "' . gettemplate( 'home_newest' ) . '";' );

}

this is line 154

Code:

$this->record = mysql_fetch_array($this->query_id);

Try...

LIMIT 0,1

That's the only thing that jumps out to me.

Your only fetching one row, hence you should be using query_first and remove the while loop.

$getnewthumb=$DB_site->query_first("SELECT * FROM gal_Pictures where Object='$newObject[ID]' ORDER BY rand() DESC LIMIT 1");

 // get a random pic

        $tmpnew=explode(".",$getnewthumb[filename]);

Neither of the {} are needed as far as I can see with that code segment.

I see Limits which are not needed on query_first.

I see an array element with no single quotes around it.

I see order by rand, but rand() will not equate to a field name, just a number.

Also, a side note: never, ever query in a loop :)

Its not stricly needed, but heres what he means:

PHP Code:


		
			
$getnewthumb[filename];

$getnewthumb['filename'];

The second being the prefered way to do it.
