When redirecting with header() after a form upload, if there is # in the redirect, it disappears in MSIE, but works properly in other browsers. I’ve made the following simple script as an example:
<?php
if (isset($_REQUEST["description"])) {
$location = "http://localhost/#someanchor";
header("Location: $location");
exit;
}
?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>PHP header redirect with #</title>
<meta http-equiv="Pragma" content="no-cache" />
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
</head>
<body>
<div>
<form enctype="multipart/form-data" method="post" action="<?php echo $_SERVER["PHP_SELF"]?>">
<div>
Description <input type="text" name="description" /><br /><br />
File <input type="file" name="uploadfile" /><br /><br />
<input type="submit" />
</div>
</form>
</div>
</body>
</html>
In Firefox and other browsers it redirects to http://localhost/#someanchor
In MSIE it redirects to http://localhost (loses the anchor)
If I remove the file input, then it works in MSIE as well! (but I need the file upload)
I could work around it with Javascript but maybe there is something I’m missing here?
This is one of the rare cases where IE stricly implements the RFC. In the Location-header, you must send an ‘absolute uri’, as defined here:
absoluteURI = scheme ":" ( hier_part | opaque_part )So, no fragment (#).
