I am not entirely sure I got your question right but I think one problem lies in the data format. I assume you are using the savemany method. The data is expected in this format:

$data = array(
    array('name' => 'Chrysanthemum.jpg', 'type' => 'image/jpeg', 'tmp_name' => '/tmp/phpDZoRzW', 'error' => 0, 'size' => 879394),
    array('name' => 'Jellyfish.jpg', 'type' => 'image/jpeg', 'tmp_name' => '/tmp/phpVyb98b', 'error' => 0, 'size' => 775702)
);

Basically you are providing the data field by field instead of record by record. I don't think that cake can process this correctly.

To get data in the desired format you can either loop through the data or use the convenience method Hash that cakephp provides, e.g. by using extract on the required keys/values.

Receive the data in the right format

If you are able to change the submit-form you name the file input fields like this. The result should be the desired format.

<input type="file" name="Report.0">
<input type="file" name="Report.1">

This will result in the format:

   [Reports] => Array
        (
            [0] => Array
                (
                    [name] => 'Chrysanthemum.jpg'
                    [type] => 'image/jpeg'
                )
            [1] => Array
                (
                    [name] => 'Jellyfish.jpg'
                    [type] => 'image/jpeg'
                )
        )

You should use MODELNAME.{n}.FIELDNAME as naming for form fields in Cakephp, though. So if reports is your model it would make sense having a field name for your file-field.

Hi Kapil, I extended my answer, covering this aspect as well. You will find more information in the documentation about naming form fields for savemany-tasks: book.cakephp.org/2.0/en/core-libraries/helpers/form.html
