get_post_mime_type()
Retrieve the mime type of an attachment based on the ID.
This function can be used with any post type, but it makes more sense with attachments.
Uses: get_post()
No Hooks.
Return
String|false. The mime type on success, false on failure.
Usage
get_post_mime_type( $post );
- $post(int|WP_Post)
- Post ID or post object.
Default: global $post
Examples
#1 Get a mime type of post
You need to get mime type posts with ID equal to 121 (this is a loaded in the media section of the WordPress html file):
$rrr = get_post_mime_type( 121 ); echo $rrr; // output: text/html
If we need to know the mime type inside a loop that uses the global variable $post, you can use this function instead:
$post->post_mime_type;
#2 Return an icon image path according to the MIME type of the given post
function get_icon_for_attachment( $post_id ) {
$base = get_template_directory_uri() . "/images/icons/";
$type = get_post_mime_type($post_id);
switch ($type) {
case 'image/jpeg':
case 'image/png':
case 'image/gif':
return $base . "image.png"; break;
case 'video/mpeg':
case 'video/mp4':
case 'video/quicktime':
return $base . "video.png"; break;
case 'text/csv':
case 'text/plain':
case 'text/xml':
return $base . "text.png"; break;
default:
return $base . "file.png";
}
}
// call it like this:
echo '<img src="'. get_icon_for_attachment( $my_attachment->ID ) .'" />';
WordPress already has a function to get the mime type icon called wp_mime_type_icon().
