My Query is :

            include('db.inc.php');
            $query = mysql_query("SELECT t1.code, t1.title, RIGHT(t2.page_name, 31) as t2.page_name, t2.hits FROM files t1 INNER JOIN hits t2 ON t1.code= RIGHT(t2.page_name, 31) as t2.page_name ORDER by t2.hits DESC LIMIT 1, 7");

            while ($result = mysql_fetch_assoc($query)) {
                echo ' <div id="linkstyle"><strong><a href="http://localhost/edu/filesupload/download.php?code='. $result['t1.code'] . ' ">' , $result['t1.title'] , '</a></strong><br></div>';
                }

I get this error

Warning: mysql_fetch_assoc() expects parameter 1 to be resource, boolean given in C:\xampp\htdocs\Edu\filesupload\index.php on line 104

Where is the problem?

Answer 1

Change this:

$query = mysql_query("SELECT t1.code, t1.title, RIGHT(t2.page_name, 31) as t2.page_name, t2.hits FROM files t1 INNER JOIN hits t2 ON t1.code= RIGHT(t2.page_name, 31) as t2.page_name ORDER by t2.hits DESC LIMIT 1, 7");

To this:

$query = mysql_query("SELECT t1.code, t1.title, RIGHT(t2.page_name, 31) as t2.page_name, t2.hits FROM files t1 INNER JOIN hits t2 ON t1.code= RIGHT(t2.page_name, 31) as t2.page_name ORDER by t2.hits DESC LIMIT 1, 7") or die(mysql_error());

Then that should tell you what the error is, because if it was fine, it wouldn’t be returning false.
