I have an java app that will send a url sting (domain.com/login.php?user=username&pass=password&etc...) to automaticly login to one site.  The other site only looks at $_Post[user] to get the login info.  I do not want to change the second website login method but i do want to login.  

Q: Is there a way I could make a script to take my url $tring [$_GET] and turn it into a post string [$_POST]?

Use $_REQUEST['name']

you really should not send passwords in the url query string, can you not set up your java app to send the data via post

Using $_REQUEST would require him to change the code on the receiving site, which he said he can't do.

You could write a proxy that converts an HTTP GET to a POST, accepting the GET request and generating a new POST request using CURL, then passing the results back to the original requester. Roughly like this:

<?php
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'http://www.postdomain.com/login.php'); //Set to your target URL
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $_SERVER['QUERY_STRING']);
curl_setopt($ch, CURLOPT_USERAGENT, $_SERVER['HTTP_USER_AGENT']);
curl_setopt($ch, CURLOPT_HEADER, 1);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_TIMEOUT, 120);
$result = curl_exec($ch);
curl_close($ch);
?>

The curl_exec will just dump whatever comes back from this POST request to the original GET requester. You might need to a be a little more careful with what you pass into CURLOPT_POSTFIELDS, but the principle should hold together. You may also need/want to pass through various other info from the original requester (in the same way as I have with user agent). Also bear in mind that this route will make it look like your server rather than the requester is the real requester, which may mean that the log works, but only for your server's IP address, depending on how they have their login script set up.

Point your java app to this PHP page, and this form's action to the real app:


<html>
<head>
<title>whatever</title>
</head>
<body>

<form method="post" action="http://......../">
<?
foreach ($_GET as $key => $value) {
  printf("<input type=\"hidden\" name=\"%s\" value=\"%s\" />", $key, $value);
}
?>
<button type="submit">Continue login...</button>
</form>
</body>
</html>

You can use Java Script to submit a form with Post values activated by a hyper link. This will give you a hyper link appearance which will submit form vaues using the post menthod.
Place this java script between your head tags. Use hidden input form fields for additioal post values sent by the java script activated submit action.

<html>
<head>
<title>Title</title>
<script language="JavaScript" type="text/javascript">
<!--
function submitlink ( postvalue )
{
  document.linkform.area_session.value = postvalue ;
  document.linkform.submit() ;
}
-->
</script>
 
</head>
<body>
<form name="linkform" action="/index.php" method="POST" >
    <input type="hidden" name="area_change" value="Change" />
    <input type="hidden" name="area_session" />
    <a href="javascript:submitlink('Members_Area')">Members Area</a><br />
    <a href="javascript:submitlink('Free_Area')">Free Area</a><br />
                        </form>
</body>
</html>
