• PHP Multiple form tokens

  - by Juddling

  I understand the idea of generating a form token and storing it in a session, and also putting it as a hidden input in my forms. But how could I make this work if I have pages with multiple forms, is it still safe to use the same token for each form? And I still feel weary about bots and stuff on my website, can these form tokens really safely replace CAPTCHAs?

• problem with IN clause in SQL

  - by user179056

  Hello, We have observed that there seems to be a maximum number of ids/variables which one can pass in the IN clause of SQL as comma seperated values. To avoid this we are storing all the ids in a table and doing a SELECT within the IN clause. This however means extra database operations to store and retrieve ids. Is there any other way to use IN without SELECT? regards Sameer

• Login system and sessions (php)

  - by Jonathan

  I've created a login page and registration page and now I want to use that to password protect pages and have pages which show information specific to that user. Would storing the user ID of the user logged in in a Session variable be a safe and correct way of doing this? How easy would it be for a user to change the session variable to a different ID and access another user's information, and not having to type the users login details in?

• How much more efficient is one big image rather than many small images. Facebook style.

  - by Jesse Gibbs

  So I was looking at the facebook HTML with firebug, and I chanced upon this image and came to the conclusion that facebook uses this large image (with tricky image positioning code) rather than many small ones for its graphical elements. Is this more efficient than storing many small images? Can anybody give any clues as to why facebook would do this.

• What good programming practices will change with C++0x?

  - by Jon

  For example, "Don't return objects by value if they are expensive to copy" (RVO can't always be used). This advice might change because of rvalue references. The same might be said about storing collections of pointers to objects, because copying them by value into the collection was too expensive; this reason might no longer be valid. Or the use of enums might be discouraged in favour of "enum class". What other practices or tips will change?

• Should multiple regional websites all use the same database?

  - by John Himmelman

  I'm developing a cms for a company that has multiple regional sites (us, uk, china, russia, etc..). Should I use a separate database for each of these sites or use a single database with a 'site' field in each table? My main concern is the table language encoding (ie, can storing strings in different langauges in the same table cause problems, such as sorting issues).
