问题
I want to POST data from my FORM to an IFRAME which is found on another domain. Is there any easy way to do this?
<iframe name="iframe" width="100" height="100" src="www.otherdomain.com" />
<form action="www.mydomain.com" method="post" target="iframe">
<input type="text" name="text1" value="123" />
<input type="text" name="text2" value="456" />
<input type="submit" value="submit"/>
</form>

I think your example should work. I've set two virtual hosts pastefrom.com pasteto.com on my localhost.
http://pastefrom.com/index.html:
<!DOCTYPE HTML>
<html>
<head>
<meta http-equiv="Content-type" content="text/html; charset=utf-8" />
<title>test</title>
</head>
<body>
<iframe name="iframe" id="iframe" src="http://pasteto.com/index.php" width="500" height="500"></iframe>
<form action="http://pasteto.com/index.php" method="post" target="iframe">
<input type="text" name="search" value="google" />
<input type="submit" value="submit"/>
</form>
</body>
</html>
http://pasteto.com/index.php:
<pre><?php var_dump($_POST);?></pre>
And on submit it shows post data on pasteto.com
array(1) {
["search"]=>
string(6) "google"
}
