public function up()
{
Schema::create(‘club_events’, function (Blueprint $table) {
$table->increments(‘id’);
$table->string(‘event_name’);
$table->string(‘description’);
$table->boolean(‘special_events’);
$table->decimal(‘event_price’);
$table->dateTime(‘from’)->nullable();
$table->dateTime(‘to’)->nullabe();

$table->integer(‘club_id’)->unsigned();
$table->timestamps();

$table->foreign(‘club_id’)
->references(‘id’)->on(‘club’)
->onDelete(‘cascade’);

});
}

Answer 1

You would compare it to the current datetime like:

if (now()->gte($clubEvent->to)) {
    // the event is expired
} else {
    // not expired
}

Here are the Carbon comparison functions.

Update the expired field like:

$clubEvent->update([
     'expired' => now()->gte($clubEvent->to)
]);

Answer 2

You should be able to just run an update query on your model:

ClubEvent::whereRaw('to < NOW()')
    ->where('expired', false)
    ->update(['expired' => true]);

If however, you want to actually find events that are in the past, but have not been expired, you can find them with another query:

$events = ClubEvent::whereRaw('to < NOW()')
    ->where('expired', false)
    ->get();

This could also be created as a query scope on your model:

public function scopeIsPast($query)
{
    return $query->whereRaw('to < NOW()');
}

You could then use your query scope instead:

ClubEvent::isPast()->update(['expired' => true]);
