<p>Allows a user to submit multiple files from a form on your WordPress site via AJAX to WordPress default uploads folder and adds an attachment to the<br />
Wordpress media gallery.  Includes a shortcode <code>[wp-multi-file-uploader]</code> for use in a form created in the post editor and a function for use in a form in a template file <code>wp_multi_file_uploader();</code>.</p>
<p><strong>Plugin Home Page:</strong> <a href="http://danholloran.me/WPMultiFileUploader/" rel="nofollow ugc">http://danholloran.me/WPMultiFileUploader/</a></p>
<p><strong>What this plugin does not do:</strong> This plugin does not make sure that the user is allowed to add a file but it does restrict the file type to the WordPress supported file types by default, this has been updated to dynamically get the supported file types for your WordPress install.  The file upload size limit is now restricted to either the WordPress or PHP INI limit this can be changed.  It also does not play nice at the moment with WordPress form building plugins, if you integrate it with one please let me know and submit a pull request this is a feature I would like to eventually get integrated.</p>
<p><strong>Both the short code and the function accept 2 parameters.</strong><br />
    allowed_mime_types accepts a comma separated white space sensitive list, ex: jpg,png,gif<br />
    max_file_size accepts the file size in megabytes ex: 4 = 4mb</p>

<p>This plugin automatically converts language accent characters in filenames when uploading to the media library. Characters are converted into browser and server friendly, non-accent characters.</p>
<h3>Features</h3>
<ul>
<li>Converts accent characters to non-accent, latin equivalents in Swedish, Danish, German, and more.</li>
<li>Removes special characters like exclamation marks, periods, hashtags, and more.</li>
<li>Lets you choose if you want to convert only image files, or all file types.</li>
<li>Makes site and server migrations easier thanks to non-accent character filenames.</li>
<li>Provides filter hook for developers who want to specify which file types to convert.</li>
</ul>
<h3>Examples</h3>
<ul>
<li>Räksmörgås.jpg <span aria-hidden="true" class="wp-exclude-emoji">→</span> raksmorgas.jpg</li>
<li>Æblegrød_FTW!.gif <span aria-hidden="true" class="wp-exclude-emoji">→</span> aeblegrod-ftw.gif</li>
<li>Château de Ferrières.png <span aria-hidden="true" class="wp-exclude-emoji">→</span> chateau-de-ferrieres.png</li>
</ul>
<h3>Worth noting</h3>
<p>The plugin only converts filenames when the files are being uploaded. It can not convert existing files.</p>
<h3>Filter for developers</h3>
<p>This filter provides developers a way to specify which file types the plugin should convert. This filter overrides the plugin settings on the media settings page. For a complete list of mime types, see <a href="http://en.wikipedia.org/wiki/Internet_media_type" rel="nofollow ugc">Wikipedia</a>.</p>
<p>The following example will convert PDF, JPEG and PNG files only:</p>
<pre><code>function my_clean_image_filenames_mime_types() {
    $mime_types = array(
        'application/pdf',
        'image/jpeg',
        'image/png',
    );
    return $mime_types;
}
add_filter( 'clean_image_filenames_mime_types', 'my_clean_image_filenames_mime_types' );
</code></pre>
