Answer 1

Give the space between the key word var and the variable name tele. Check the following line.

var tele = $("#tele").val();

Answer 2

add space in variable declaration. and while posting data dont give a space. For Eg:

             type:"POST",
             url:"<?php echo base_url(); ?>staff_activity/date_report",
             data:'year='+nep_year+'&month='+nep_month,

Answer 3

Your root problem is the space you've embedded within the query string in this part:

... +'& tele ='+ tele

Remove the space between & and tele ...

... +'&tele ='+ tele

HOWEVER, you don't need to collect each value and manually construct a query string.

Simply use jQuery .serialize() , which collects the form's values and constructs the query string automatically.

data:  $('form').serialize(),
