Prevent from posting twice a day!

[rvbcrs]

Hai,

I'm from Holland so please forgive me my English. I'm new to PHP and I'm working on a for you guys I think a simple script.
1. The user fills in the form.
2. The script submits the data in to a file.
3. If the user submits again on the same day I want the script to check if there has already been written into that file on that day, if so the script has to give an error. And this last thing I can't get done. So my question:

How can I let the script check if there has been a post on that day, so that a user cant post data to the file twice on the same day.

Thank you in advance,
Ramon

Hello fellow dutchie.

If you are just writing to a file you can check the file's accessdate to see on which date you last wrote to the file.

http://www.php.net/manual/en/ref.filesystem.php

check out the fileatime() function.

Hmm that's an option but is there a way to check the last line of the file if it is the same as the data of the FORM POST?

So the last line of my file is:
blabla

and with an <input> I try to post the var $whatever witch contains 'blabla' then I want the script to give an error because the last line of the file is the same as the data I try to post...

Technically you could do that, but the last line would have to be a date or something to find out if it's posted on the same day or not.
