Question

I have a MySQL database that I’m working with, but when I try to update a row in it, it doesn’t work. Here’s the update code I’m working with:

mysql_query('UPDATE offtopic SET next = '$insert' WHERE id = '$id''); 

Answer 1

First of all, you should make it a bit more safe:

mysql_query(sprintf('UPDATE offtopic SET next = '%s' WHERE id = '%s'',             mysql_real_escape_string($insert),             mysql_real_escape_string($id)); 

Now, is your id actually string, and not numeric? If its numeric, you should rather have:

mysql_query(sprintf('UPDATE offtopic SET next = '%s' WHERE id = %d',             mysql_real_escape_string($insert), $id);
