Add media to posts and pages (even Custom Post Types!) to quickly and easily generate download lists for your content.
<h4>Features include</h4>
<ul>
<li>Simple per-post management of downloadable media</li>
<li>Use the familiar WordPress media screen to upload or add files</li>
<li>Use a single shortcode, <code>[pamd]</code>, to add downloads to your content</li>
<li>Advanced users may call functions directly in their themes to implement download areas outside the post content</li>
</ul>
<h4>Advanced use</h4>
If you wish to make use of media downloads in your theme, you can call the <code>get_downloads()</code> function directly in the following way;
<pre><code>$pamd->get_downloads( $postID, $echo, $return_format, $target )
</code></pre>
All parameters are optional, and if no downloads are found the function will return false. The parameters control the following;
$postID integer
The ID of the post you wish to fetch, if none is provided the id form The Loop will be used
$echo boolean
Should the content be echoed or returned
$return_format string
What format should the list be returned in, the default is an unordered list
<ul>
<li><code>array</code> returns an array of the media</li>
<li><code>table</code> returns a table with the media</li>
<li><code>pamd</code> (default) returns an unordered list with the media</li>
</ul>
$target string
This attribute is only used if you are returning a table or the default behavior is left, and will determine the target attribute of the link
