Is it possible to allow zip files to be uploaded in Wordpress?

I have the following code but it doesn't work.

function custom_upload_mimes($existing_mimes = array()) {

// Add *.EPS files to Media upload
    $existing_mimes['eps'] = 'application/postscript';
// Add *.AI files to Media upload
    $existing_mimes['ai'] = 'application/postscript';
// Add *.AI files to Media upload
    $existing_mimes['3ds'] = 'application/postscript';
// Add *.dwg files to Media upload
    $existing_mimes['dwg'] = 'application/acad';
// Add *.dwg files to Media upload
    $existing_mimes['dwg'] = 'application/x-acad';
// Add *.dwg files to Media upload
    $existing_mimes['dwg'] = 'application/autocad_dwg';
// Add *.dwg files to Media upload
    $existing_mimes['dwg'] = 'application/dwg';
// Add *.dwg files to Media upload
    $existing_mimes['dwg'] = 'application/x-dwg';
// Add *.dwg files to Media upload
    $existing_mimes['dwg'] = 'application/x-autocad';
// Add *.dwg files to Media upload
    $existing_mimes['dwg'] = 'drawing/dwg';
//add .zip
    $existing_mimes['zip'] = 'application/zip';

    return $existing_mimes;
}

add_filter('upload_mimes', 'custom_upload_mimes');

Here is a action that works on my site:

add_filter('upload_mimes', 'custom_upload_mimes');
function custom_upload_mimes ( $existing_mimes=array() ) {
    // add your extension to the mimes array as below
    $existing_mimes['zip'] = 'application/zip';
    $existing_mimes['gz'] = 'application/x-gzip';
    return $existing_mimes;
}

If you are using WP MultiSite you can configure the behavior the following way (tested in WP 3.8.1):

• Go to the network settings in your browser: http://example/wp-admin/network/settings.php
• Scroll down to the bottom of the settings page and you will find a list of allowed file types, add zip to it.

In 5.0.3 (probably already earlier): For multisite (at least), you can edit the allowed extensions and add zip in the network settings. No need to edit files anymore.
