使用php mysqli将时间戳提交到mysql数据库

Question

I have this database (mysql):

And I have code:

$day = $app->request->post('day');
            $startLocation = $app->request->post('startLocation');
            $datum = new DateTime();
            $startTime = $datum->getTimestamp(); //this line is IMPORTANT
            global $user_id;
            $db = new DbHandler();

            // creating new task
            $day_id = $db->createDay($user_id, $day, $startLocation, $startTime); ETC...

but I cant submit that timestamp data into database in startTime witch have type timestamp

Why? How to do that?

Answer 1

If your column data type is TIMESTAMP , then it should be:

$datum = new DateTime();
$startTime = $datum->format('Y-m-d H:i:s');

Note: ->getTimestamp() returns unix timestamp

And modify your wrapper function:

public function createDay($user_id, $day, $startLocation, $startTime) { 
    $stmt = $this->conn->prepare("INSERT INTO days(day,startLocation,startTime) VALUES(?,?,?)"); 
    $stmt->bind_param('sss', $day, $startLocation, $startTime); // change the d into s in your types
    $result = $stmt->execute(); 
    $stmt->close();
}
