num_rows()?

why won't this work?

PHP Code:


		
			
    $totalquery = $DB_site->query_first("SELECT* FROM grps WHERE title LIKE '%" . addslashes($search) . "%' ORdescription LIKE '%" . addslashes($search) . "%'");
    $totalresults = number_format($DB_site->num_rows($totalquery));

the error i'm getting is

Code:

Warning: mysql_num_rows(): supplied argument is not a valid MySQL result resource in \includes\db_mysql.php on line 312

PHP Code:


		
			
$totalquery = $DB_site->query("SELECT * FROM grps WHERE title LIKE '%".addslashes($search)."%' OR description LIKE '%".addslashes($search)."%'");



$totalresults = number_format($DB_site->num_rows($totalquery));

Using query fiirst returns the first row, not the identifier.

You should use COUNT(), not SELECT *.

[sql]
SELECT COUNT(unique id column name) AS totalcount FROM grps WHERE title LIKE "expression%
[/sql]
It will return a single result row with a column name of totalcount containing the number of matching rows.

Don't forget TABLE_PREFIX.

it's because he wrote "SELECT*" instead of "SELECT *"
