Laravel 5.3 date validator: equal to or after start_date

Question

I'm using Laravel 5.3 to validate start_date and end_date for an event. end_date should be equal to start_date or the after date. end_date >= start_date

$validator = Validator::make($data, [     'start_date'    => 'required|date',     'end_date'      => 'required|date|after:start_date', ]); 

I tried to use after, but it only works for end_date > start_date. Of course, I can add custom rule using Validator::extend, but I'd like to know if we can do without adding custom rule.

Is there any way to add negative rule or add >= rule?

Thanks

Answer 1

$validator = Validator::make($data, [     'start_date'    => 'required|date',     'end_date'      => 'required|date|after_or_equal:start_date', ]); 

Use after_or_equal

Be careful when you set a validation rule after_or_equal:now and date_format with a format without hours, minutes or seconds!

For example:

$validationRules = [     'my_time_start' => [         'date_format:Y-m-d',// format without hours, minutes and seconds.         'after_or_equal:now'     ] ]; 

Laravel passing all date fields into the strtotime() function. Including now string. And strtotime('now') will return a unix timestamp with current minutes, hours and seconds.

For example, the today date is 2020-05-03. When you send a date value 2020-05-03 into your script, Laravel will pass 2 values into the strtotime() for compare:

strtotime('2020-05-03'); // always 1588489200 strtotime('now'); // NOT PREVIOUS VALUE, a different value each second, timestamp including current minutes, hour and seconds. 

And you will always fail a validation (exclude a 1 second of the day).

To fix it, you should use:

$validationRules = [     'my_time_start' => [         'date_format:Y-m-d',// format without hours, minutes and seconds.         'after_or_equal:' . date('Y-m-d'), // not 'now' string     ] ];
