Laravel plusieurs colonnes uniques
$table->unique(['mytext', 'user_id']);
Tough Tarsier
$table->unique(['mytext', 'user_id']);'name' => 'unique:table,field,NULL,id,field1,value1,field2,value2,field3,value3'// in my case, just add more unique rule
'phone1' =>'string|unique:tbl_users,phone1|unique:tbl_users,phone2|different:phone2|min:2',
'phone2' =>'string|unique:tbl_users,phone2|unique:tbl_users,phone1|different:phone1|min:2',
