Forcing A Unique Rule To Ignore A Given ID
You can specify an ID to be ignored as the optional third parameter. Furthermore, if your table uses a primary key column name other than id, you may specify it as the optional fourth parameter
'email' => "unique:{$table},{$field},{$user->id},{$idField}"
So in your case, it'd be as follows
'email' => "unique:email_list,email,{$user->id},user_id'
