2.0.15 -> 2.0.16: QueryString.php failed

[t-geronimo]

Hello Forum, I have a little problem with the file "./Sources/QueryString.php" .

Code Select Expand

[search]
$buffer = preg_replace_callback('~"' . preg_quote($scripturl, '/') . '\?((?:board|topic)=[^#"]+?)(#[^"]*?)?"~', 'pathinfo_insert__preg_callback', $buffer);
}

Code Select Expand

[replace]
// Be nice and try to inject session tokens into login forms since many older themes don't.
if ($user_info['is_guest'])
$buffer = preg_replace_callback(
'~(<form[^<]+action=login2(.+))</form>~iUs' . (!empty($context['utf8']) ? 'u' : ''),
function ($m) use ($context)
{
$repl = '';
if (strpos($m[0], $context['session_var']) === false)
$repl .= '<input type="hidden" name="' . $context['session_var'] . '" value="' . $context['session_id'] . '"/>';

return $m[1] . $repl . '</form>';
},
$buffer
);

The part that the update searches for does not exist in my file
Since I run SMF 2.0.15, my "QueryString.php" is still given with 2.0.9.
Shall I just manually replace the file after running the auto update or shall another method be prefered?

Many thanks for your support!

You can but that fix is not needed for most people unless you have a custom theme that has not been updated yet.
That's what that code is for to fix older themes missing the hidden input field for login verification.

All right, many thanks for your fast support!
