Nejčastější dotazy

My chosen featured image doesn’t show, why isn’t it working?

This plugin works out of the box for most cases, but not always. If it doesn’t work you can try the following things.

  • Switch themes. Most of the time the theme does something weird.
  • Are you using the Core WordPress functions to get the image? (see the FAQ below this one).
  • Do normal feature images work?
  • Might it be hidden via css? DFI images have an extra default-featured-img class added to them.

Still having problems? I want to know if it fails, so contact me

Which functions can I use to display the featured image?

There are no new functions, all core WordPress functions can be used.

Can I set a different image for a custom post type?

Yes, the following code will set a different image.

add_filter( 'dfi_thumbnail_id', 'dfi_posttype_book', 10, 2 );
function dfi_posttype_book( $dfi_id, $post_id ) {
    $post = get_post( $post_id );
    if ( 'book' === $post->post_type ) {
        return 31; // the image id for the book post type.
    }

    return $dfi_id; // the original featured image id.
}

Can I set different images per category?

Yes, the following snippet will set different images based on the category.

add_filter( 'dfi_thumbnail_id', 'dfi_category', 10, 2 );
function dfi_category( $dfi_id, $post_id ) {
    // Set a different image for posts that have the 'cats' category set.
    // This will trigger first, if multiple categories have been set.
    if ( has_category( 'cats', $post_id ) ) {
        return 7; // cats img id.
    }
    // Set a different image for posts that have the 'cats' category set.
    if ( has_category( 'dogs', $post_id ) ) {
        return 8; // dogs img id.
    }

    return $dfi_id; // the original featured image id.
}

Can I change the HTML of the default featured image?

When a Default Featured Image is used it will already add an extra class default-featured-img.
This can be used for styling.

If you need more you can change the whole HTML with the filter dfi_thumbnail_html.

add_filter( 'dfi_thumbnail_html', 'dfi_add_class', 10, 5 );
function dfi_add_class( $html, $post_id, $default_thumbnail_id, $size, $attr ) {
    // Add a class to the existing class list.
    $attr['class'] .= ' my-class';

    return wp_get_attachment_image( $default_thumbnail_id, $size, false, $attr );
}

Can I exclude one page from having a Default Featured Image?

The following code will exclude the post/page with ID 23.

add_filter( 'dfi_thumbnail_id', 'dfi_skip_page', 10, 2 );
function dfi_skip_page( $dfi_id, $post_id ) {
    if ( $post_id == 23 ) {
        return 0; // invalid id.
    }

    return $dfi_id; // the original featured image id.
}

Thank you, @janwoostendorp, for this great minimalist and out-of-the-box working plugin. I was looking for a plugin that’d set a default image to posts that don’t have any, and this plugin is doing exactly that—nothing more, nothing less. It’s not creating yet another admin menu bar item with dozens of subpages. It doesn’t annoy you with constant dashboard notices. It doesn’t beg for donations or includes any watermarks. It just works the way you expect it to work. It’s a little sad that the bar is this low, but compared to so many other plugins, I think this needs to be pointed out—and reach more people who want a simple solution for a simple problem. The only feature I’d have liked to see is the support for images that are unavailable and can’t be displayed to also use the default featured image. A quick glance inside the code showed quite a bit of jQuery, which wouldn’t be my first choice, but it made me think that adding a simple checkbox to have it checking for this (non-render blocking, of course) could be a useful idea. Thanks for your work!

Default featured image does what it’s supposed to do and it meets two criteria I always look for: light weight it just works The support forum has good answers to questions, and that’s a big plus.Thanks for the great plugin.

Es perfecto porque hay una opción que te pone automáticamente la imagen destacada de todos los post que no la tenían cogiendo la primera imagen del post y si no hay imagen lo deja vacío. Perfecto!!
