문제
We have about 2000 files in our media library and we are working on an audit to organize the files and create a name hierarchy.
But until that is done, I am trying to locate a handful of specific files to replace. I don't know what the files are named in Wordpress, I only have the URL to download the file.
Is there a way to search for the file in the dashboard using the URL?

Based on my research, you would need to run a query on directly on the database using WPDB. So you would do something like this:
Add this in your functions.php
file:
// retrieves the attachment ID from the file URL
function get_image_id($image_url) {
global $wpdb;
$the_attachment = $wpdb->get_col($wpdb->prepare("SELECT ID FROM $wpdb->posts WHERE guid='%s';", $image_url ));
return $the_attachment[0];
}
And then you can apply it wherever you like this way:
$attachment_url = 'http://example.com/wp-content/uploads/2020/10/28/just_for_the_lolz.jpg';
$attachment_id = get_image_id($image_url);
$attachment_id
will have the attachment ID so you can do whatever you want with it.
