Question

I made a php script to counts the number of users have viewed my website’s pages. This is my code

<?php   
    require_once ('test.php');

    $institute_id = 14;

    $q = "INSERT INTO page_views2 ( institute_id, views) VALUES ( $institute_id, 1)
         ON DUPLICATE KEY UPDATE views=views+1"
         ; 
    $r = mysqli_query ($dbc, $q);

?>

I added this to top of my webpages and this is working (views incrementing) properly when I open the pages. But my problem is When I refresh the page, page views is incrementing by 1. It is okey when it is open first time. But I want to avoid from this when someone is refreshing the page.

so can any body tell me how can I do this?

Answer 1

Use sessions?

require_once ('test.php');

$institute_id = 14;

//if no such session exists, assume that its their first time viewing.
if(!isset($_SESSION[$institute_id.'_v'])){

    //insert
    $q = "INSERT INTO page_views2 ( institute_id, views) VALUES ( $institute_id, 1)
         ON DUPLICATE KEY UPDATE views=views+1"
         ; 
    $r = mysqli_query ($dbc, $q);

    //set session variable saying they've viewed this institutions page.
    $_SESSION[$institute_id.'_v'] = 1;

}
