Precis:
I was trying to submit a form divided into sections, each
section having a two text fields and a file upload. The
form was structured as an array called $section, each
element an array containing firstname, surname and image.

The image details I expected to turn up in $HTTP_POST_FILES as $HTTP_POST_FILES[section][0][name] etc. That behaved as
expected.

The other form elements I expected to turn up as
$HTTP_POST_VARS[section][0][firstname] etc. However
what I ended up with was $HTTP_POST_VARS[section][0]
being set to the filesize of the uploaded file, overwriting
all other elements in that section.


// ---------------start upload.php--------------------------
<?php
print "<pre>\nVars:\n";
print_r($HTTP_POST_VARS);
print "\nFiles:\n"; 
print_r($HTTP_POST_FILES);
print "</pre>\n";
?>

<form method='post' enctype='multipart/form-data'>
   <input type='text' name='section[0][firstname]'> <br>
   <input type='text' name='section[0][surname]'> <br>
   <input type='file' name='section[0][image]'> <br> 
   <input type='submit'>
</form>
// ---------------end upload.php----------------------------

// ---------------start input ------------------------------
  section[0][firstname] = foo
  section[0][surname]   = bar
  section[0][image]     = ~/feathers.gif
// ---------------end input --------------------------------

// ---------------start output -----------------------------

Vars:

(
    [section] => Array
        (
            [0] => 12409
        )

)

Files:

(
    [section] => Array
        (
            [0] => Array
                (
                    [name] => Array
                        (
                            [image] => feathers.gif
                        )

                    [type] => Array
                        (
                            [image] => image/gif
                        )

                    [tmp_name] => Array
                        (
                            [image] => /tmp/phpwwJSPf
                        )

                    [size] => Array
                        (
                            [image] => 12409
                        )

                )

        )
