I have added a custom taxonomy 'Elements' to my Wordpress Media Library so I can tag images and sort them by tag.
I now want to output all the images automatically in an taxonomy-elements.php archive template (or archive-elements.php?).
So for example all images with the Elements tag 'light' would appear at /elements/light.
I also want to query all Elements tags to display a list of links anywhere on the site that would link to these archive pages. this list would also display the amount of images for each tag.
e.g:
Elements: Light(5) Space(2) Red(4) Blue(8)
My registered custom taxonomy:
// register new taxonomy which applies to attachments
function wptp_add_elements_taxonomy() {
$labels = array(
'name' => 'Elements',
'singular_name' => 'Element',
'search_items' => 'Search Elements',
'all_items' => 'All Elements',
'parent_item' => 'Parent Element',
'parent_item_colon' => 'Parent Element:',
'edit_item' => 'Edit Element',
'update_item' => 'Update Element',
'add_new_item' => 'Add New Element',
'new_item_name' => 'New Element Name',
'menu_name' => 'Elements',
);
$args = array(
'labels' => $labels,
'hierarchical' => true,
'query_var' => 'true',
'rewrite' => 'true',
'show_admin_column' => 'true',
);
register_taxonomy( 'elements', 'attachment', $args );
}
add_action( 'init', 'wptp_add_elements_taxonomy' );
Trying to output images from the Elements custom taxonomy:
function get_images_from_media_library($elements) {
$args = array(
'post_type' => 'attachment',
'post_mime_type' =>'image',
'post_status' => 'inherit',
'posts_per_page' => -1,
'orderby' => 'rand',
'tax_query' => array(
array(
'taxonomy' => 'elements',
'field' => 'slug',
'terms' => $elements
)
)
);
$query_images = new WP_Query( $args );
$images = array();
foreach ( $query_images->posts as $image) {
$images[]= $image->guid;
echo $image->ID; // Returns image ID, but I need it in display_images_from_media_library function
}
return $images;
}
function display_images_from_media_library($elements) {
$imgs = get_images_from_media_library($elements);
foreach($imgs as $img) {
$html .= '<img src="' . $img . '" alt="">';
}
return $html;
}
