First let’s create the function and the shortcode. Go to your themes folder and open functions.php. If you don’t have one, just create a new file named functions.php and save it to your themes folder.

Create a new function with the following code.

function get_attachment_icons($echo = false){
	//PDF Documents
	if ( $files = get_children(array(   //do only if there are attachments of these qualifications
	 'post_parent' => get_the_ID(),
	 'post_type' => 'attachment',
	 'numberposts' => -1,
	 'post_mime_type' => 'application/pdf',  //MIME Type condition
	 ))){
	 foreach( $files as $file ){ //setup array for more than one file attachment
		$file_link = wp_get_attachment_url($file->ID);    //get the url for linkage
		$file_name_array=explode("/",$file_link);
		$file_name=array_reverse($file_name_array);  //creates an array out of the url and grabs the filename
		$sAttachmentString .= "<div class='documentIcons'>";
		$sAttachmentString .= "<a href='$file_link'>";
		$sAttachmentString .= "<img src='".get_bloginfo('template_directory')."/images/mime/pdf.png'/>";
		$sAttachmentString .= "</a>";
		$sAttachmentString .= "<br>";
		$sAttachmentString .= "<a href='$file_link'>$file_name[0]</a>";
		$sAttachmentString .= "</div>";
		}
	}

This block is for PDF files. You can tell that by the line that says ‘post_mime_type’ => ‘application/pdf’,. Just change the MIME type for the type of file you are expecting. In the final code, I’ve added a new loop for each MIME type below:

• PDF = application/pdf
• Word Documents = application/msword
• PowerPoint = application/vnd.ms-powerpoint
• Excel = application/vnd.ms-excel
• Zip = application/zip
• Audio files = audio/mpeg

Now at the bottom of the function we will add the hook for the shortcode and we’re done!

add_shortcode('attachment icons', 'get_attachment_icons');

Usage

Just include a shortcode in any post

[attachment icons]

or place one line in your single.php file (or where ever you’d like the document icons to show up)

<?php get_attachment_icons($echo=true); ?>

Final Code

Here is the code altogether for your copying and pasting pleasure. Enjoy!

function get_attachment_icons($echo = false){
	$sAttachmentString = "<div class='documentIconsWrapper'> \n";
	if ( $files = get_children(array(   //do only if there are attachments of these qualifications
	 'post_parent' => get_the_ID(),
	 'post_type' => 'attachment',
	 'numberposts' => -1,
	 'post_mime_type' => 'application/pdf',  //MIME Type condition
	 ))){
	 foreach( $files as $file ){ //setup array for more than one file attachment
		$file_link = wp_get_attachment_url($file->ID);    //get the url for linkage
