wordpress - How does one grab an attachment ID of file types that are not images? -


i've found terrific number of tutorials/code examples provide code grab , echo attachment id of image, not single 1 works else, such zip , rar archives - precisely i've working with.

would know how go grabbing , echoing id of file (in case, zip archive) within wordpress attachment.php page? oddly enough, grabbing id of zip archive appears simple when attempted via single.php, i'm struggling nail within attachment.php.

really can't understand why wordpress has built-in get_post_thumbnail_id(); images, nothing available other type of file.

refer example show attachments current post beside thumb on (ironically, given comments!) get_post_thumbnail_id() codex page.

basically set get_posts() query all attachments. you'd need filter results on file type extension, or if know (and it's recorded correctly), wp_post.post_mime_type using get_post_mime_type().

(the example filters out featured image/thumb too... filter take care of anyhow).

but if can use mime type filter, can set get_posts() args 'post_mime_types' argument, return attachments of 1 (or more) specific mime type(s). you'd want take peek @ attachments' underlying database entries check how recorded can match against it. expect .zip files application/zip, i'd double check before relying on that.

so, like:

<?php  $args = array(     'post_type'   => 'attachment',     'numberposts' => -1,     'post_status' => null,     'post_parent' => $post->id,     'post_mime_type' => 'application/zip'     );  $attachments = get_posts( $args );  ?>
