Status: Open
Bug Type: mbstring related
Operating System: Win XP Pro

New Comment:
with the version of the form I posted, the expected and actual result
sample data should obviously reflect the strings "John" and "Doe"
instead of "billy" and "joel", respectfully.

Description:
------------
If key contains more than one set of square brackets, the key value
pair is not decoded properly. For example, a form with a series of
input elements named such as "formname[0].fieldname[0]" will cause
incorrect and missing key/value pairs to be stored into the $_POST
array.
In researching the existing bug list, I noticed that there have been
numerous variations of bugs reported when form data contains url
encoded data, such as occurs when the brackets are encoded as %5b and
%5d. However these bugs have apparently been closed without actually
fixing this problem. Perhaps a more thorough analysis of this problem
is warranted to keep it from lingering on for a few more years before
this report is closed. The Adobe acrobat products/reader have just
started to encode form names in this format, so it could become a very
serious issue if PHP cannot correctly process this form data.
Reproduce code:
---------------
<html>
<head><title>Form Submit Test Script</title></head>
<body>
<form name='fm1' action="<? echo ($_SERVER["HTTP_REFERER"])?>"
method='post'>
<input type='text' name='form1[0].firstname[0]' value='John' />
<input type='text' name='form1[0].lastname[0]' value='Doe' />
<input type='submit' />
</form>
<?
var_dump($_POST);
?>
</body>
</html>
Expected result:
----------------
array(2) { ["form1[0].firstname[0]"]=> string(5) "billy"
["form1[0].lastname[0]"]=> string(4) "joel" }
Actual result:
--------------
array(1) { ["form1"]=> array(1) { [0]=> string(4) "joel" } }
