html - Admin back end - get URL of file using file browser

admin管理员组

文章数量:1302418

I would like to be able to get the URL of a html file that has been uploaded to a folder via FTP.

So if I go into a post in the admin back end of WordPress, I would like there to be a custom field with a file browser that would list the html files and subdirectories in: wp-content/uploads/articles/

Then when a file has been selected it will log the url of that file so it can be retrieved on the front end.

I've done countless searches on Google and here and can't seem to find the answer I'm looking for. Would just like to know if it can or cant't be done so I can plan accordingly.

Any insight would be greatly appreciated!

You can scan the directory for files with glob() then loop throw the results and list them in a admin modal (thickbox) or just show the list within a admin metabox in the post editor.

Here's a little snippet that i was playing with.

/**
 * Get HTML Article Files from uploads/articles
 * Support both .htm & .html ext.
 * 
 * @return array List of html article files with path & url.
 */
function wpse_384622_get_articles() {
    $uploads   = wp_upload_dir();
    $file_path = $uploads['basedir'] . '/articles/';
    $file_url  = $uploads['baseurl'] . '/articles/';
    $articles  = [];
    foreach ( glob( $file_path . '*.htm*' ) as $path ) {
        if ( is_readable( $path ) ) {
            $file_type = wp_check_filetype( $path );
            if ( 'text/html' === $file_type['type'] ) {
                $file_list[] = [
                    'path' => $path,
                    'url'  => str_replace( $file_path, $file_url, $path ),
                ];
            }
        }
    }
    
    return $articles;
}
