Add another image js function

I'm using a WordPress plugin called User Submitted Posts. The plugin allows for users to upload multiple photos. I have it set up so that users can upload 0 to a max of 3. When I try to upload more than one pic, however, only one of them gets posted.

HTML:

<div id="usp"> 
    <form id="usp_form" method="post" enctype="multipart/form-data" action=""> 


        <ul id="usp_list"> 
                        <li class="usp_title"> 
                <label for="user-submitted-title" class="usp_label">Post Title</label> 
                <div> 
                    <input class="usp_input" type="text" name="user-submitted-title" id="user-submitted-title" value="" /> 
                </div> 
            </li> 
                        <li class="usp_tags"> 
                <label for="user-submitted-tags" class="usp_label">Post Tags <small>(separate tags with commas)</small></label> 
                <div> 
                    <input class="usp_input" type="text" name="user-submitted-tags" id="user-submitted-tags" value="" /> 
                </div> 
            </li> 
                        <li class="usp_content"> 
                <label for="user-submitted-content" class="usp_label">Post Content</label> 
                <div> 
                    <textarea class="usp_textarea" name="user-submitted-content" id="user-submitted-content" rows="5"></textarea> 
                </div> 
            </li> 
                                            <li class="usp_images"> 
                    <label for="user-submitted-image" class="usp_label">Upload an Image</label> 
                    <div id="usp_upload-message"></div> 
                    <div> 
                                                <input class="usp_input usp_clone" type="file" size="25" id="user-submitted-image" name="user-submitted-image[]" /> 
                                                <a href="#" id="usp_add-another">Add another image</a> 
                    </div> 
                </li> 
                                        <li class="usp_submit">

== Template Tags ==

To display the images attached to user-submitted posts, use this template tag:

<?php post_attachments(); ?>

This template tag prints the URLs for all post attachments and accepts the following paramters:

<?php post_attachments($size, $beforeUrl, $afterUrl, $numberImages, $postId); ?>

$size = image size as thumbnail, medium, large or full -> default = full $beforeUrl = text/markup displayed before the image URL -> default = <img src=" $afterUrl = text/markup displayed after the image URL -> default = " /> $numberImages = the number of images to display for each post -> default = false (display all) $postId = an optional post ID to use -> default = uses global post

Additionally, the following template tag returns an array of URLs for the specified post image:

<?php get_post_images(); ?>

This tag returns a boolean value indicating whether the specified post is a public submission:

<?php is_public_submission(); ?>

What does var_dump($_FILES) look like? It looks like you're generating a unique field name for each file upload field, using $key = "public-submission-attachment-{$i}";. if that's the case, then your file access structure is incorrect. PHP will generate the $_FILES data for each fieldname 1 of 2 ways:

1. If you're using a unique somestring field name, you get a structure like:

   $_FILES['somestring'] = array(
      'name' => 'somefile.txt',
      'type' => 'text/plain',
      'size' => 1234,
      'error' => 0,
      'tmp_name'] => '/tmp/asdfasdfasdfa'
   );
   

2. If you're using the PHP-centric array notation, somestring[] (note the []) for the field name, you get:

   $_FILES['somestring'] = array(
      'name' => array(
           0 => 'somefile1.txt',
           1 => 'somepic.jpg'
      ),
      'type' => array(
           0 => 'text/plain',
           1 => 'image.jpeg'
      )
      etc...
   );
   

Given that it you seem to be generating a unique field name, WITHOUT the array notation, you'd have to use option #1.
