Jon –
Don’t know if you still are trying to accomplish this, but I was today, and came up with the following solution:
This works on WC 2.0.12 and WP 3.5.2
I also included different file types – .xls and .doc files should also be able to be attached.
The only change I made is I added custom icons to my theme directory in <themedirectory>/icons – the pdf one must be named pdf.png. Excel is vnd.ms-excel.png and Word is msword.png. These are all based on the MIME types of the files, FYI.
I prefer a recognizable icon for those files to the default that WP provides.
Only code needed is added to functions.php:
// Add downloads tab if pdf attachment is present
add_filter( 'woocommerce_product_tabs', 'cg_product_downloads_tab');
function cg_product_downloads_content() {
$args = array(
'post_type' => 'attachment',
'orderby' => 'menu_order',
'numberposts' => -1,
'post_status' => null,
'post_parent' => $post->ID,
'post_mime_type' => array( 'application/pdf','application/vnd.ms-excel','application/msword' )
);
$attachments = get_posts( $args );
if ( $attachments ) {
foreach ( $attachments as $attachment ) {
// SETUP THE ATTACHMENT ICON
$attachment_icon = $attachment->post_mime_type;
$attachment_icon = explode( '/',$attachment_icon ); $attachment_icon = $attachment_icon[1];
$attachment_icon = '<img src="' .get_bloginfo('template_directory'). '/icons/' . $attachment_icon . '.png" alt="' . get_the_title($attachment->ID) . '" title="' . get_the_title($attachment->ID) . '" />';
echo '<p><a href="';
echo wp_get_attachment_url( $attachment->ID );
echo '">';
echo $attachment_icon;
echo wp_get_attachment_image( $attachment->ID );
echo ' ';
echo apply_filters( 'the_title', $attachment->post_title );
echo '</a>';
echo '</p>';
}
}
}
function cg_product_downloads_tab($tabs) {
$args = array(
'post_type' => 'attachment',
'numberposts' => -1,
'post_status' => null,
'post_parent' => $post->ID,
'post_mime_type' => array( 'application/pdf','application/vnd.ms-excel','application/msword' )
);
$attachments = get_posts( $args );
if ( $attachments ):
$tabs['test_tab'] = array(
'title' => __( 'Downloads', 'woocommerce' ),
'priority' => 50,
'callback' => 'cg_product_downloads_content'
);
endif;
return $tabs;
}
Now you just upload a file to a product, and if it is one of the listed MIME types (pdf, word, excel) it will display on a Downloads tab in your product automagically! If there are no such attached files, the tab will not display.
Enjoy!
