Php MySQL updating a column only if IP is new - php

Question

I'm trying to make my script update the view count by +1 everytime a IP is new.
and after 604800 seconds, if the same user(same IP) comeback again after 604800 seconds view count by+1.
Can someone help me out here.
//Get video id
$id = $_GET['id'];
//Get video title
$videoName = $_GET['idtitle'];
//Connect to database
$pdo = new PDO('mysql:host=localhost;dbname=videodb', 'root', '');
$pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
//Get user IP
$ip = $_SERVER["REMOTE_ADDR"];
//Insert that user IP, Name, Title and increase view count by +1
//This is what i want to accomplish but is not working!
$insert = $pdo->query("INSERT INTO `videodb`.`videos` ( `ip`, `name`, `title`, `views`) VALUES ('$ip', '$id', '$videoName', `views`+1)");
// Sample Two
//Select the IP from videos
$select = $pdo->prepare("SELECT `ip` FROM `videos`");
$sql = $select->execute();
while ($row = $select->fetch(PDO::FETCH_ASSOC)) {
//If the IP in database is not equal to the user IP in database views +1
if($row->fetch('ip') == $ip){
$pdo->query("UPDATE videos SET `views` = `views`+1 WHERE id = '$id' ");
}}

Answer 1

Add one more column in your table as last_viewed_at DATETIME.
Now before inserting the record into the database:
As you are checking the the record for the last 7 days then query as like below:
$row = "SELECT * FROM videos WHERE
id = 'users.ip.to.check'";
Conditions: You have got record against the users.ip.to.check
now check whether the time difference is more than 7 days.
means.
if (count($row) > 0) {
$ipLastViewAt = new \DateTime($row['last_viewed_at']);
$currentDate = new \DateTime();
$diff = $currentDate->diff($ipLastViewAt)->format("%a");
if ($diff >= 7 ) {
// update the record with the view + 1 and with last_view_at = currentDateTime;
}
} else {
// Insert the record with the view +1 and with last_view_at = currentDateTime;
}

If Ip is unique field then this query should help
INSERT INTO `videodb`.`videos`( `ip`, `name`, `title`, `views`) VALUES ('$ip', '$id', '$videoName', 1) ON DUPLICATE KEY UPDATE `views`=views+1;

Answer 3

is not a full code,just for your information!
Tips:two tables maybe better,one save video info,another save visitor info
videos:id,ip,name,title,views,update_time
// first, select $video info and get the result --- "select * from videos where ip='{$ip}' and id='{$id}'";
// we got $video look like : array('id'=>1,'update_time'=>'1453970786')
$time = time();
if( isset($video['id']) && (($time - $video['update_time']) >= 604800) ){
$pdo->query("UPDATE `videodb`.`videos` SET `views`=`views`+1 AND update_time='$time' WHERE id = '$id'");
}elseif( !isset($video['id']) ){
$pdo->query("INSERT INTO `videodb`.`videos`( `ip`, `name`, `title`, `views`) VALUES ('$ip', '$id', '$videoName', 1)");
}
edit
$pdo->query("INSERT INTO `videodb`.`videos`(`id`, `ip`, `name`, `title`, `views`) VALUES ('$id','$ip', '$id', '$videoName', 1)");
