Need testers on my website
if you submit it over at my site http://www.fixedbeforehacked.com me and my team will take a look at your site as well. Seems though you need to patch quite a few things from previous posts in this thread, but i will take a look and see what i can find.
well for sql injections, make sure you put quotes around every thing like instead of:
$sql="SELECT * FROM table WHERE id=$id";
put this instead of above
$sql="SELECT * FROM table
WHERE id='$id'";
also use the function addslashes() to make sure they can't put in ' or " in to mess up the query. what really helps is having magic_quotes turnen on in the php.ini file however you may not have access to that since you are on a free hosting site.
