Refresh a page using PHP

You can do it with PHP:

header("Refresh:0");

It refreshes your current page, and if you need to redirect it to another page, use following:

header("Refresh:0; url=page2.php");

reload a specific section of a web page

Inside the success of your ajax, replace the html of your old post div with new post content. $("#old_post_div").html("new_post_content");
Or you can use prepend or append so that the new content will be prepended or appended along with old content.

How to refresh a specific div of a page in PHP?

function refresh_box() 
{
    $("#myDiv").load('path your PHP file');
    setTimeout(refresh_box, 60000);
}

$(document).ready(function(){
   refresh_box();
});

this setTimeout call your function for every 1 minute and load content dynamically in mydiv.

refresh part of php page

To refresh only part of a webpage you can use AJAX. It is based on JavaScript and lets you update certain parts of a webpage without reloading it.

Refresh Part of Page (div)

Use Ajax for this.

Build a function that will fetch the current page via ajax, but not the whole page, just the div in question from the server. The data will then (again via jQuery) be put inside the same div in question and replace old content with new one.

Relevant function:

http://api.jquery.com/load/

e.g.

$('#thisdiv').load(document.URL +  ' #thisdiv');

Note, load automatically replaces content. Be sure to include a space before the id selector.

How to auto refresh a section of a page

You could use a Javascript library such as jQuery and do something like the following simplified example:

$("document").ready(function(){
  var interval = setInterval(refresh_box(), 60000);
  function refresh_box() {
    $("#myDiv").load('path/to/databasepage.php');
  }
} /*<= The closer ) bracket is missing in this line*/

and in your path/to/databasepage.php page you can have your select query and echo the results out.

What this does is sets a timeout to call a function (in this case, refresh_box() ) every 60 seconds (which is 60,000 miliseconds) and loads the data from path/to/databasepage.php in to your div with the id myDiv.

edit:

If you want to stop the auto-refresh you can bind an element to clear the interval by doing the following:

// assuming you have a clickable element 
// (typically a button or so) id called 'stop_refresh'
$("#stop_refresh").click(function(){
  clearInterval(interval);
}
