[backbone]

aloha!

was ist hierdrann bitte syntaktisch falsch??? ich find den fehler einfach nicht.

$edit_data = "UPDATE user SET 'email' = 'email_strip' , 'aboutme' = '$aboutme_strip' , 'wort' = '$wort_strip' , 'icq' = '$icq_strip' , 'msn' = '$msn_strip' , 'yahoo' = '$yahoo_strip' , 'hp' = '$hp_strip' WHERE 'username' = '$username'";

mysql gibt folgenden fehler aus:

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 ''email' = 'email_strip' , 'aboutme' = 'momentan...öhm...don't :D
