如果刀片模板中的更新时间少于8小时，则显示消息

Maybe is something simple but I have one submit form which I want to restrict so user should be able to update it once per 8 hours.

I have updated_at column in database table which store last update time in timestamp : 2016-10-21 09:56:13

Now in my blade template I've tried to check like this

@if($time->updated_at < 8 hour)                 
    // show message to come back after 8 hours                                                          
@else
    // show the form
@endif

I've got

'syntax error, unexpected 'hour' (T_STRING)'

I know why I got this but I don't how to make the if... do I need to convert current time and then how to present 8 hours? Like 60*60*8?

Assuming your updated_at is using Laravel's default timestamps

@if((time() - strtotime($time->updated_at)) < 28800)                 
    // show message to come back after 8 hours                                                          
@else
    // show the form
@endif

if you are using larvel timestamps than updated_at is always the object of carbon so you can use carbon to get difference between current date/time and your model updated_at

@if(Carbon\Carbon::now()->diffInHours($time->updated_at) > 8)
//time difference is greater than 8
@else
// time difference is less than or equal to 8 hours
@endif
