You just need to write a delete avatar function that gets the location of the file and deletes it using the php unlink function. The following code can be used as an example of how it’s done. I use this to delete the old user avatars when a user uploads a new one. It is … Read more
I haven’t touched user functions so far, but according to the codex, should look something like this. $args = array( ‘meta_key’ => ‘g300’, ‘meta_value’ => ‘,’ ); $users = get_users( $args ); EDIT This assumes that all the users with the field unchecked have a comma value ( for example, it won’t work if the … Read more

There’s get_the_author_meta() for such a task. (get_* functions normally don’t echo/print the output – hence the name). // Both values are *optional* get_the_author_meta( $field, $user_id ); Normally it’s only meant to be used inside a loop to get the data of the posts author, therefore it internally uses global $authordata;. But, you can also throw … Read more

Don’t use update_usermeta, it is deprecated, update_user_meta is the one to use. You get the previously saved value out with get_user_meta. <input type=”text” name=”group[]” id=’group[]’ class=”regular-text” value=”<?php echo esc_attr( get_user_meta( $user->ID, ‘group’, true ) ); ?>” />
