How to create a date field input form in prestashop ?

I want to create a date form field where I could add a start date and an end date.And I want to add a condition that the start date should be always smaller than the enddate.

 

{html_select_date start_year=1970 month_format="%b" field_order="dmy" field_array="sdate" prefix="" day_id="edd" class="form-control" style="width:160px;background-color:#F6F6F6;" month_id="edm" year_id="edy" year_empty="Year" month_empty="Month" day_empty="Day" time=$from|escape name="from"}
