Automatic posting to multiple websites

lajkonik86

Hey i would like to make a service which posts something to multiple websites at once.
However these websites have no APIs, also have no captcha though.
How can i best structure my code to automate the submission using object oriented coding. Im trying to figure out a way which would easily be maintainable when the websites undergo changes. Also which functions would you use to do this?

Sounds like you'll need to set up your PHP pages with a form to accept user postings. Once you receive the user's input, you are going to have to POST to the other sites using [man]cURL[/man] or some other method.

Not sure how to make it object-oriented. It would probably make sense to make a class for each remote site you'd like to post to. If the site changes, you just tweak the class to reflect the site's changes. Another class might be the cURL routines to submit their forms and such.

Curl was also what I was thinking about.
Do not know any other solutions which could achieve the same result.

Regarding the classes you have to take into account that the process of posting to the sites will be pretty similar for each site. How do i keep it flexible without duplicating lots of code?

You can just use 'for' statements to keep the code small if each site works in the same way. I think you can post data using fsockopen or something like that also.

you could post to pages directly using file_get_contents and a stream context, its more useful than most people think:

// first, build a stream context instructing to send a POST with the given header and form data
$context = stream_context_create(
  array(
    'http' =>
    array(
      'method' => 'POST',
      'header' => 'Content-Type: application/x-www-form-urlencoded',
      'content' => 'name=val&name=val&name=val' # urlencoded form data
    )
  )
);

// then actually send the request, and retrieve the full response
$response = file_get_contents('http://www.example.com/someform.html', FALSE, $context);
