Works fine here, debug your code.

Mozilla autofilled some of the fields when I submitted this bug and so
it had a completely unrelated/unhelpful summary. Hopefully it should
be corrected now, sorry for the confusion...

Description:
------------
If you give a form input a name that should be a numerically indexed
array, such as
<input type='text' name='fname[1]' />
It is not possible to directly access the variable via $_GET, $_POST,
or $_REQUEST.
Dumping the entire contents of the request using e.g. print_r reveals
that the form data is submitted, but it cannot be accessed via e.g.
$_POST['fname']['1'] or $_POST['fname'][1]
Presumably this happens because the PHP engine is doing type juggling.
When a request variable is submitted and looks like an array, the PHP
puts it in an array and indexes the value at the string value '1'.
However, when you try to access $_POST['fname']['1'] it sees that '1'
could be an integer, converts to an integer transparently to the
developer, and of course there is nothing stored at $_POST['fname'][1].
The data was stored at $_POST['fname']['1'].
For whatever reason, embedding the variable in a string appears to
solve the problem. E.g., "{$_POST['test'][1]}" works
Reproduce code:
---------------
echo "<pre>"; // So we can use \n for formatting
echo <<<EOT
<form method='GET' action='{$_SERVER['PHP_SELF']}'>
<input type='text' name='test[1]' value='{$_REQUEST['test'][1]}'/>
<input type='submit'/>
</form>
EOT;
echo '('.gettype($test[1]).') value='.$test[1]."\n";
echo '('.gettype($test[1]).') value='.$test['1']."\n";
echo "But it works if we embed in a string --->
{$_REQUEST['test'][1]}\n";
var_dump($_REQUEST['test']);
// Put a string variable in the textbox and submit.
// If using GET method, URL might look like
// bugTest.php?test%5B1%5D=any+string+here
Expected result:
----------------
(string) value=any string here
(string) value=any string here
But it works if we embed in a string ---> any string here
Array
(
[1] => any string here
)
Actual result:
--------------
(NULL) value=
(NULL) value=
But it works if we embed in a string ---> any string here
Array
(
[1] => any string here
)
