Laravel Eloquent Calculate

Question

I have a Model and want to insert something into the database.

One of the fields should add a number to the current value (timestamp)

$purchases = new PurchasesModel($this->connection);
$purchases->updates_until = 'updates_until + ' . $updates_included_time;

This does of course not work, so how can i do that?

The updates_until field is formatted as timestamp (but since mysql 4.1 handled as datetime) in the database, $updates_included_time is a int value which should be added to the timestamp.

Answer 1

Simply use the increments method:

PurchasesModel::where('id', '=', 1)
              ->increment('updates_until', 'INTERVAL ' . $updates_included_time . ' SECOND');

You may change SECOND to MINUTE , or whatever suits you better.
