I have created a dynamic table using php.Now I want to add this functionality.

When we click the submit button, It should automatically add data to the database and create new row and previous row should be disabled that it can't be edited.How to do this ? 

<?php 
session_start();
require_once "header.php";
?>

Reset to default 4

Try simply disable the all previous row input with $('tr').find('input').prop('disabled',true) before new row append .

Jquery Documentation of prop()

Updated jquery version 3.2.1 

$(document).ready(function() {
  var i = 1;
  $("#add_row").click(function() {
  $('tr').find('input').prop('disabled',true)
    $('#addr' + i).html("<td>" + (i + 1) + "</td><td><input type='text' name='uid" + i + "'  placeholder='User ID' class='form-control input-md'/></td><td><input type='text' name='uname" + i + "' placeholder='Name' class='form-control input-md'/></td><td><input type='text' name='nic" + i + "' placeholder='NIC' class='form-control input-md'/></td><td><input type='text' name='amount" + i + "' placeholder='Amount' class='form-control input-md'/></td><td><input type='date' name='dt" + i + "' placeholder='Date' class='form-control input-md'/></td>");

    $('#tab_logic').append('<tr id="addr' + (i + 1) + '"></tr>');
    i++;
  });
});

Add $('#addr'+(i-1)).find('input').attr('disabled',true); to your logic

Demo : https://jsfiddle/kw4koyvk/

$(document).ready(function(){
      var i=1;
     $("#add_row").click(function(){
      $('#addr'+(i-1)).find('input').attr('disabled',true);
      $('#addr'+i).html("<td>"+ (i+1) +"</td><td><input type='text' name='uid"+i+"'  placeholder='User ID' class='form-control input-md'/></td><td><input type='text' name='uname"+i+"' placeholder='Name' class='form-control input-md'/></td><td><input type='text' name='nic"+i+"' placeholder='NIC' class='form-control input-md'/></td><td><input type='text' name='amount"+i+"' placeholder='Amount' class='form-control input-md'/></td><td><input type='date' name='dt"+i+"' placeholder='Date' class='form-control input-md'/></td>");

      $('#tab_logic').append('<tr id="addr'+(i+1)+'"></tr>');
      i++; 
  });
});
