Ticket #760 by @patrickatimarc

If i fill out the first two of three fields everything is fine. if I fill out one and three I get an error "The index specified, 1, is invalid for the field attachments"

Can you provide the HTML for the inputs and the PHP code you are using to upload the files?

Sho can:

<div class="attachment">
    <input type="file" name="attachments[]">
    <a class="remove_attachment">- remove this attachment</a>
</div>

<div class="attachment">
    <input type="file" name="attachments[]">
    <a class="remove_attachment">- remove this attachment</a>
</div>

<div class="attachment">
    <input type="file" name="attachments[]">
    <a class="remove_attachment">- remove this attachment</a>
</div>

<p id="add_attachment"><a>+ Add Attachment</a></p>

if (!empty($_FILES)) {
    fUpload::filter('attachments');
    $uploader = new fUpload();
    $uploader->setMaxSize('5m');
    for ($i=0; $i < fUpload::count('attachments'); $i++) {
        $attachments[] = $uploader->move($_SERVER['DOCUMENT_ROOT'] . '/uploads/', 'attachments', $i);
    }
}
