    You can’t get the id. The id attribute is never sent to the server when you submit an form. That’s how HTML works. Only the value is sent. But checkboxes are a little different because only the value attribute of the checked checkboxes is sent to the server.

    So, simply use the value attribute for that purpose:

    <input id="1" type="checkbox" value="1" name="dias">
Lunes
<input id="2" type="checkbox" value="2" name="dias">
Martes
<input id="3" type="checkbox" value="3" name="dias">
Miercoles
<input id="4" type="checkbox" value="4" name="dias">
Jueves
<input id="5" type="checkbox" value="5" name="dias">
Viernes
<input id="6" type="checkbox" value="6" name="dias" checked="checked">
Sabado
<input id="" type="checkbox" value="" name="dias">
Domingo

    Now in your string[] dias parameter you will get a list of the selected ids. Then if you need to get the corresponding names go ahead and query your data store where they reside given this id.
