Take a look at FAQ for the basic questions.

FAQ
-
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.
- the_post_thumbnail / get_the_post_thumbnail Display the image.
- the_post_thumbnail_url / get_the_post_thumbnail_url Get the url.
- has_post_thumbnail If a DFI is set it will always return true.
- get_post_thumbnail_id will return the ID set on the post or the DFI.
-
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. }
