i see what you are referring to now. when testing your code it returns me
the original url that i send the curl_POST_redirect function, not the
redirect one.

  I was thinking - do the POST request, get the first returned
  redirection URL, then use that URL for standard (GET) requests, using
  the full curl_redir_exec function:

  <?PHP
  //Use this function to POST the page and parse the redirect location
  header out of the response
  function curl_POST_grab_redirect($url,$postfields){
  $ch = curl_init(); //initialize curl handle
  curl_setopt($ch, CURLOPT_URL, $url); //set url to post to
  curl_setopt($ch, CURLOPT_VERBOSE, 1);
  curl_setopt($ch, CURLOPT_FAILONERROR, 1);
  curl_setopt($ch, CURLOPT_COOKIEFILE, "/tmp");
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); //return into variable
  curl_setopt($ch, CURLOPT_TIMEOUT, 24); //timeout after 25s
  curl_setopt($ch, CURLOPT_POST, 1); //set POST method
  curl_setopt($ch, CURLOPT_POSTFIELDS, $postfields); //add post fields
  curl_setopt($ch, CURLOPT_AUTOREFERER, 1);
  //curl_setopt($ch, CURLINFO_HEADER_OUT, true);
  $result = curl_exec($ch); //run the whole process
  list($header, $data) = explode("\n\n", $data, 2);
  $http_code = curl_getinfo($ch, CURLINFO_HTTP_CODE);
  //echo "HTTP CODE: $http_code<br>";
  if ($http_code == 301 || $http_code == 302)
  {
  echo "code is 301 or 302";
  $matches = array();
  preg_match('/Location:(.*?)\n/', $header, $matches);
  $url = @parse_url(trim(array_pop($matches)));
  }
  return $url;
  curl_close($ch);
  unset($ch); //clean up
  }

  //POST and get the url
  $theurl = curl_POST_grab_redirect("http://yoursite.com/page.php","key=value&so=on&so=forth");
  //proceed with curl_redir_exec
  $ch2 = curl_init();
  curl_setopt($ch2, CURLOPT_GET, 1); //this is set by default anyway
  curl_setopt($ch2, CURLOPT_URL, $theurl); //from the function
  /* Add any other options as needed */
  $res = curl_redir_exec($ch2);
  ?>

    In order to first post I must tell curl to use POST, which I have
    done with:

    curl_setopt(

    $ch, CURLOPT_POSTFIELDS, $postfields);

    Since I need to do a GET after this, don't I have to do a
    CURLPT_HTTPGET after or else it will still try to post?

    I believe that's the issue I'm having from the beginning. How to
    do a POST then a get. I'm under the impression that I have to
    write code to switch between the two. I'm also a little confused
    of I should code what you describe.

    Here is my main function along with the one you describe. How
    would I modify it to do GET?

    list($header, $data) = explode("\n\n", $data, 2);

    $http_code = curl_getinfo($ch, CURLINFO_HTTP_CODE);

    //echo "HTTP CODE: $http_code<br>";

    if ($http_code == 301 || $http_code == 302)

    {

    curl_setopt(

    $ch, CURLOPT_POST, 0); //turn off POST method

    curl_setopt(

    $ch, CURLOPT_HTTPGET, 1); //set GET method

    //curl_setopt($ch, CURLOPT_DEBUGFUNCTION,1);

    curl_setopt(

    $ch, CURLOPT_POSTFIELDS, NULL);

    echo "code is 301 or 302";

    $matches = array();

    preg_match(

    '/Location:(.*?)\n/', $header, $matches);

    $url = @parse_url(trim(array_pop($matches)));

    }

    function

    curl_navigate($url,$postfields){

    $ch = curl_init(); //initialize curl handle

    curl_setopt(

    $ch, CURLOPT_URL,$url); //set url to post to

    curl_setopt(

    $ch, CURLOPT_VERBOSE, 1);

    curl_setopt(

    $ch, CURLOPT_FAILONERROR, 1);

    curl_setopt($ch, CURLOPT_COOKIEFILE, "/tmp");

    curl_setopt(

    $ch, CURLOPT_RETURNTRANSFER, 1); //return into variable

    curl_setopt(

    $ch, CURLOPT_TIMEOUT, 24); //timeout after 25s

    curl_setopt(

    $ch, CURLOPT_POST, 1); //set POST method

    curl_setopt(

    $ch, CURLOPT_POSTFIELDS, $postfields); //add post fields

    curl_setopt(

    $ch, CURLOPT_AUTOREFERER, 1);

    //curl_setopt($ch, CURLINFO_HEADER_OUT, true);

    curl_redir_exec(

    $ch);

    $result = curl_exec($ch); //run the whole process

    return $result;

    curl_close(

    $ch);

    }

      Hey,
      After the first POST, you only need that little snippet from
      the function to get the new Location header.
      Once you've got the new URL from your special POST request,
      you can actually just use the full function for the rest of
      your requests.
      About using GET, unless you explicitly tell cURL to use POST
      or PUT or something, it defaults to a GET request, so you
      shouldn't have to worry.

        stephen, i see you displayed only a little bit of the
        redirect function. are you suggesting i omit the rest?
        also, how do you do a get request? use the
        CURLOPT_HTTPGET? oh and one more thing. should this be
        a seperate function since you mention i should do the
        POST as normal? thanks,ryan

          My recommendation would be to do your first POST
          request normally, then take the data you get and use
          a little bit of the redir_exec function:

          list($header, $data) = explode("\n\n", $data, 2);
          $http_code = curl_getinfo($ch, CURLINFO_HTTP_CODE);
          if ($http_code == 301 || $http_code == 302) {
          $matches = array();
          preg_match('/Location:(.*?)\n/ ', $header, $matches);
          $url = @parse_url(trim(array_pop($matches)));

          To get the next URL, then just do a while loop, with
          a cURL GET request in it, until there are no more
          URLs.

            i'm trying to figure out how i can do a "post"
            then a "get". due to restrictions on my server,
            i have to use the redirect script found on
            php.net: function curl_redir_exec($ch,$debug="")
            {
            static $curl_loops = 0;
            static $curl_max_loops = 20; if ($curl_loops++ >=
            $curl_max_loops)
            {
            $curl_loops = 0;
            return FALSE;
            }
            curl_setopt($ch, CURLOPT_HEADER, true);
            curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
            $data = curl_exec($ch);
            list($header, $data) = explode("\n\n", $data, 2);
            $http_code = curl_getinfo($ch,
            CURLINFO_HTTP_CODE);
            if ($http_code == 301 || $http_code == 302) {
            $matches = array();
            preg_match('/Location:(.*?)\n/', $header,

            /* if (!$url['scheme'])
            $url['scheme'] = $last_url['scheme'];
            if (!$url['host'])
            $url['host'] = $last_url['host'];

            $url['path'] = $last_url['path'];*/
            $new_url = $url['scheme'] . '://' . $url['host']
            .
            $url['path'] .
            ($url['query']?'?'.$url['query']:'');
            curl_setopt($ch, CURLOPT_URL, $new_url);
            // debug('Redirecting to', $new_url); return
            curl_redir_exec($ch);
            } else {
            $curl_loops=0;
            return $data;
            } i have my curl_setopt to POST, but need to do
            GET also. how do setup my code so that i post
            and then do a get for the next few redirects?
