Ahoj dnes podruhé.

Potřeboval bych poradit kde mám problém v kodu:

<?php
$query = "SELECT id, img, info, youtube, autor FROM popis WHERE autor=$autor ";
$result = mysql_query($query) or die(Mysql_error());
While($results=MySQL_Fetch_Assoc($result))
{

 print "\t\t" . '<img width="100" height="100" src="' . $results['img'] .'">' . "\n"; 

              ?> 

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
