But the calendar opens only in first "block" of inputs. In the next "blocks", when I click on calendar input the javascript is not called. Where I need to do changes?

Answer 1

i think you have identical IDs, every returned row (in this case 106, 157) has same id (ar, de)

there are two options:

a) when you call datepicker, use class selector

<script>
$(function(){
  $('.date').datepicker();
});
</script>

<input type="text" class="date" />

b) rename ids with row id

where you have to specify each row id in script function and make diferent input ids eg

echo '<input type="text" id="ar_'.$row['id'].'" />';
echo '<input type="text" id="de_'.$row['id'].'" />';
