Can I display the caption from the media library?

Hi blackjaic,

Glad you like the plugin! ??

There is in fact a filter that will do exactly what you want. If you look at the Installation tab under the Developers section you’ll see the documentation for dg_icon_template along with a few other filters that you may find helpful.

Let me know if you have any additional questions!

Thanks! That worked nicely. This will save us time going forward. I really like how quickly and easily the thumbnails get built on the fly!

Fantastic! I’m glad everything worked well for you.

Please don’t hesitate to ask if you have any further questions in the future.

I am developing a new website, and DG works great for what I want to do.

I would also like to add the image caption to my gallery, just like blackjaic did on his swcp website. I know enough about code to be dangerous, and I’ve read the documentation referenced in the Installation tab, but I haven’t quite put it all together to make it work.

Specifically, I think I understand that the template file goes into a subdirectory of the plugin named templates. But I am lost as to what the code should look like to render the caption like blackjaic did.

I would be grateful if someone could give me a few pointers to get me going in the right direction.

Thanks!

Hi Ron,

Since this thread was last active, the approach I’m recommending has changed slightly. There is a WordPress plugin (Code Snippets) that allows you to put bits of PHP code in without having to mess with any of the normal complications that might be involved.

With Code Snippets installed, you would want to add a snippet that looks something like this:

function dg_icon_template($icon, $use_descriptions, $id) {
     if ( $use_descriptions ) {
	     $attachment = get_post( $id );
	     $icon = str_replace( '%description%', $attachment->post_excerpt, $icon );
     }
     return $icon;
 }
 add_filter( 'dg_icon_template', 'dg_icon_template', 10, 3 );
