Using PHP cURL to update and submit a form

[Izzy Kiefer]

Hey guys,

I've hit a brick wall trying to login to an ssl site to update fields of a form and submit, mainly because(i'm guessing) it has a load of javascript within it and also a several redirects at and after login page. I have managed to come to the page after login and which lists my purchased domains, but when i make cURL fetch the dns manager link at this point it shows me the login page again. Basically im trying to update my A(IP Address) record for izzfx.com everytime my isp changes my ip address. this php script would run in bg with php-cli and evry 10 secs or so check my ip address through a website that returns your external ip address and if its different than the one that was previously recorded, auti login to dnsmanager and update values of A Address Record form and submit.

I was wondering if u guys could asist me in suggesting a different approach to this problem.

Thanks in advance, Izzy

Can you post the code then explain the issue. It will be easier for everyone.

I think you missing something. I don't think you post the right file?

Since I feel you don't really know what I'm talking about here is a link of an example of CURL:

http://www.html-form-guide.com/php-form/php-form-submit.html

and this one is much suited for your situation if know where to used this code for your code:
