Laravel 4 Validation is Broken

问题

A simple date format mm/dd/yyyy validation is all I need...

$rules = array(
    'renewal_date' =>  array('required', 'date_format:?')
    );

What do I set the date format to? The Laravel documentation could be so much better.

回答1:

Documentation is pretty clear to me, you should use

date_format:format

"The field under validation must match the format defined according to the date_parse_from_format PHP function."

Looking at it: http://php.net/manual/en/function.date-parse-from-format.php, I see you can do something like this:

$rules = array(
    'renewal_date' =>  array('required', 'date_format:"m/d/Y"')
    );

This is pure PHP test for it:

print_r(date_parse_from_format("m/d/Y", "04/01/2013"));

You can also do it manually in Laravel to test:

$v = Validator::make(['date' => '09/26/13'], ['date' => 'date_format:"m/d/Y"']);
var_dump( $v->passes() );

To me it's printing

boolean true

I got a similar problem, but with a d/m/Y date format. In my case, the problem was that I defined both "date" and "date_format" rules for the same field:

public static $rules = array(
    'birthday' => 'required|date|date_format:"d/m/Y"',
    ...

The solution is to remove the "date" validator: you must not use both. Like this:

public static $rules = array(
    'birthday' => 'required|date_format:"d/m/Y"',
    ...

after that, all is well.

Workaround:

'renewal_date' => array('required', 'date_format:m/d/Y', 'regex:/[0-9]{2}\/[0-9]{2}\/[0-9]{4}/')

回答4:

You should use with double quote like "Y-m-d H:i:s"

$rules = array(
    'renewal_date' =>  array('required', 'date_format:"m/d/Y"')
                                                      ^     ^ this ones
);

date_format didn't work for me , so I did this custom validation

Validator::extend('customdate', function($attribute, $value, $parameters) {
  $parsed_date = date_parse_from_format ( "Y-m-d" , $value);
  $year = $parsed_date['year'];
  $month = $parsed_date['month'];
  $month = $month <= 9 ? "0" . $month : $month;
  $day = $parsed_date['day'];
  $day = $day <= 9 ? "0" . $day : $day;
  return checkdate($month, $day, $year);
});

$validation = Validator::make(
  array('date' => $num),
  array('date' => 'customdate')
);

Use the PHP date_parse_from_format (Laravel 4):

'birthday' => 'date_format:m/d/Y'

Your validation message will also use "m/d/Y" which the average user will not understand. The birthday does not match the format m/d/Y

Recommend customizing your message for this invalid response. The birthday does not match the format mm/dd/yyyy

You can use like

$rules = [
    'start_date'        => 'date_format:d/m/Y|after:tomorrow',
    'end_date'          => 'date_format:d/m/Y|after:start_date',
];
