Question

I have a PHP file with a code to increase the page views on each page visit. Summarized, it’s something like this:

design.php

...
public function increase_views() {
    global $db;
    $sql = "UPDATE ".self::$table." SET views = views + 1 
            WHERE id = {$this->id}"; 
    $db->run($sql);
}

index.php

<?php
require_once(design.php); 
...
$design->increase_views();
echo $design->views;
?>
...
<script src="javascript/validate.js" type="text/javascript"></script>
<script...
<script...
...

This increase_views() methods increases in 1 the view field in the database. However, each occurrence causes an additional increment. Since I have 3 tags, the views increase 4 by 4 instead of 1 by 1. But if I REMOVE the tags, it increases correctly (+1).

What could be the cause of this?

Answer 1

Do those JavaScript files exist? If not, they may be redirecting to a 404 PHP page that calls your increase_views() function.
