Auto Populate file field from Ultimate Member Profile/Avatar when using WP Job Manager Field Editor

functions.php

<?php
add_filter( 'field_editor_auto_populate_company_logo', 'smyles_auto_populate_get_um_user_profile' );

function smyles_auto_populate_get_um_user_profile( $value ){

	$user_id = get_current_user_id();

	// Set user ID
	um_fetch_user( $user_id );

	// Get current user avatar
	$avatar_uri = um_get_avatar_uri( um_profile( 'profile_photo' ), 32 );

	// Returns default UM avatar, e.g. https://ultimatemember.com/wp-content/uploads/2015/01/default_avatar.jpg
	$url = ! empty( $avatar_uri ) ? $avatar_uri : um_get_default_avatar_uri();
	
	// Remove any query args from the URL
	return strtok( $url, '?' );
}

This assumes the meta key is company_logo to auto populate for, if you want to use a different meta key, change company_logo in the code above to the correct meta key.

Two caveats with this as well:
You can NOT use the auto save feature to user meta, as this will NOT update the ultimate member profile image
When a user updates a listing with a new image, this will NOT update the ultimate member profile image

Reason being is that Ultimate Member does NOT save the full image URL to the user's meta (or even an attachment ID), all it saves is the filename which leaves us no way to update it correctly.
