title: How to refresh a section of HTML page
body: <p>I require a section in my HTML page which will update whenever user perform a successful data entry. The data entry comes from input from user into MySQL database, then I will query the table filter by status is Success and sort by creation date DESC. </p>
  
  <p>I do not want to refresh the whole page, just the section/div (I don't know which practice to use). What are the best method to achieve this? Ajax? iframe?</p>
