Drupal 7: Determine if a Path was Viewed by a User in a Given Timeframe

  • Dan Harris

Below is a method to determine if a user has visited a page on your site within the last four weeks at login, and if not, remind them what a wonderful page it is.

Code for determining if a Drupal page was visited image

You can accomplish exactly that by calling the following function from hook_login():

/**
* Check if a site url has been visited in a specified interval.
*
* @param $uid The user ID of the user to check.
*   Example: 200 
*
* @param $path The internal Drupal path.
*   Example: 'node/1' or 'mypage'
*
* @param $interval An interval MySQL understands
*   Example: '5 DAY' or '5 WEEK' (note value is not plural)
*/
function check_page_visited_in_time_interval ($uid, $path, $interval) {
 if (module_exists('statistics')) {
   // Original SQL
   $sql = 'SELECT timestamp FROM `accesslog` 
           WHERE uid = $uid 
           AND path = $path 
           AND `timestamp` > UNIX_TIMESTAMP(DATE_SUB(NOW(), INTERVAL $interval));';        

   $date = date_create();
   date_modify($date, '-'.$interval);
   $interval =  $date->format('U');

   $result = db_query("
   SELECT timestamp 
   FROM accesslog
   WHERE uid = :uid 
   AND path = :path
   AND timestamp > :interval",
   array(':uid'=>$uid,
         ':path'=>$path,
         ':interval'=>$interval))->fetchAll();
             
   foreach($result as $r) {
     $time[$r->timestamp] = $r->timestamp;
   }
   $rowcount = count($time);
   if ($rowcount > 0) {
     return TRUE;
   }
 }
 return FALSE;
}
?>
