Why do I get the following error? and How to fix?

Warning: mysql_num_rows(): supplied argument is not a valid MySQL result resource in/home/gaogier/public_html/pages/monsters.php on line 217

If i add the or die part, I get this message.

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '' at line 1

What do I do?

Thanks.

Here is my code

<?php

    }
    if(empty($desc)){

    }    
    if(empty($pages)){

You can try:

if(!mysql_num_rows($result) || mysql_num_rows($result) == 0) 
{  
    echo "<b>Not Found</b>";  
}

or

 (mysql_num_rows($result) < 1)

If that still doesnt work, then the problem is before that, with your select statement.

0

Missing quotes:

$query = "SELECT * FROM monsters WHERE id='$id'"

If that doesn't work, var_dump your $id and make sure it's being set properly

0

You can do without the quotes if id is an integer column. I think the query fails because $id does not have a value.
