Martynas, Unfortunately the latest git version is broken for me. At least in libraries/chart.lib.php on line 5 you use a lower case filename which does not match in case-sensitive environments. Some other points: * Please use curly braces even in situations where they are technically optional. Not: if (is_null($options)) return; but if (is_null($options)) { return; } * Please make sure you properly escape variables you print to the user. $sql_query in tbl_chart.php should probably have htmlspecialchars() In general ... distrust any data you get from the outside. Most code looks OK though, nice going. -- Met vriendelijke groet / Regards, Herman van Rink Initfour websolutions
