Post & show post without page loading - HOW ?

I saw various sites and also in this forum that
when I quick reply on any post by the reply box from bottom of the page then the page not load again after submit and show the submitted reply on same page without reloading the whole page.

How can I make a form page in php like this? please help.

 

You need Ajax, check http.request method or something like that

 

Can anbody post such Ajax script or url....

AJAXing the Web

 

You might want to try some AJAX frameworks, but basically what you have to do for your required results is to send posting form values to a PHP script (ie. post.php), and then append the answer to the posts column in your forum.

 

anybody can post examples or sites url where will found script freely
