php curl log in

i'm quite new to curl, i need to log in to a certain page every hour. i had a curl code that would submit the details and log me in fine using

markupcurl_setopt ($ch, CURLOPT_POSTFIELDS, 'form1=username&form2=stuff.....');

the webiste has about 4 forms that need to be filled in to submit. but 3 of them are hidden and dont really do anything

i realised this morning that the 3 hidden form names & some of their values needed to log in are changed every 24 hours, probably to stop exactly what i want to do.

so instead of me sending the form names are values myself (because they are always changing) i imagine there would be a simpler code to just go to the webpage, enter in 1 form, click submit, and let the other 3 hidden ones stay as per normal.

any ideas? or help? cheers

You can use curl to first access the login page and then extract the other 3 forms. Store the login page in a variable and use php functions to find the values.

okay thanks, i will practice with curl a bit more and figure it out

Hey, you want some code I used for making a bot to play a browser game?

sure, i will have a look through and see if i understand how it works

Here it goes. It might be a bit confusing, but that's because it uses specifics of the website I coded it for. For example, to log in I have to get some hidden values and then log in, which is I guess what you are trying to do. If you have any questions, ask.
