May 10.2010

Hi,

I have a large form. The submit button doesn’t work if the data to be posted back is too long. Would you please share with me:

  • 1.

    How to send only MODIFIED fields back?

  • 2.

    What’s the max len of the data I can sent back using post method? Does it depend on browser?

    • I really appreciate your help!

    April?

  • 1. Set all unmodified fields to [I]disabled[/I] before posting.


  • 2. Usually limited be server configuration. If you are reaching this limit then the form design is probably flawed.
