Examples
#1 Get a link to a file icon by its type
Let's create a function that will return a link to a file icon, based on the file extension passed. Use function wp_mime_type_icon( $mime ) to get a link to the icon.
function get_icon_by_file_extension( $file_ext ) {
$mimes = get_allowed_mime_types();
foreach ( $mimes as $type => $mime ) {
if ( strpos( $type, $file_ext ) !== false ) {
return wp_mime_type_icon( $mime );
}
}
}
echo '<img src="'. get_icon_by_file_extension('mp4') .'" />';
Outputs: <img src="/core/wp-includes/images/media/video.png" />
