I have for display attachmet on page this function
$attachments = get_posts( array(
'post_type' => 'attachment',
'posts_per_page' => -1,
'post_parent' => $post->ID,
'exclude' => get_post_thumbnail_id()
) );
if ( $attachments ) {
foreach ( $attachments as $attachment ) {
// Assuming $attachment_id contains the ID of the attachment
$attachment_metadata = wp_get_attachment_metadata($attachment->ID);
if ($attachment_metadata) {
// Get file size in bytes
$file_size = filesize(get_attached_file($attachment->ID));
// Convert file size to human-readable format
$file_size_human = size_format($file_size);
// Get file type
$file_type = $attachment_metadata['mime_type'];
//$file_type = get_post_mime_type($attachment->ID);
$file_url = wp_get_attachment_url( $attachment->ID);
$filetype = wp_check_filetype( $file_url );
// Display file size and type
//echo '<p>File Size: ' . $file_size_human . '</p>';
//echo '<p>File Type: ' . $filetype['ext'] . '</p>';
$link = wp_get_attachment_link($attachment->ID);
echo '<li>' . $link . '( ' . $file_size_human . ', ' . $filetype['ext'] .')</li>';
``` }
this work how I want, but now I have duplicated attachment on a page because one is server wit the_content() function. Which is bet way to modify dipslay content for page with my attachment link display.
excludeand othernotstyle operators are extremely slow/expensive and very heavy on the server, it's much easier to addif ( $attachment->ID === get_post_thumbnail_id() ) { continue; }and could give a huge performance boost. The DB is optimised to give you what you want, it isn't optimised to exclude/hide what you don't want. Likewise setposts_per_pageto a high value you know the server can handle, but never-1, your page can't display an infinite number of posts. Otherwise your Q appears to boil down to "how do I skip an attachment if it's already in the content?"
