Cakephp 3.2 change default date format

Question

I try to set the default date format of CakePHP 3.2 from dd.mm.YYYY to YYYY-mm-dd, so I will not have to use $MyDatas->mydate->format('Y-m-d'), and what is more important in forms while editing data I will have date in format dd.mm.YYYY (ex- 27.02.2016). I need YYYY-mm-dd (2016-02-27).

I looked for solutions and none display any changes (in forms or as part of view: $MyDatas->mydate):

// in AppController

ini_set('intl.default_locale', 'pl_PL');

//and/or

use Cake\Database\Type;
Type::build('datetime')->useLocaleParser()->setLocaleFormat('YYYY-mm-dd');

//and/or

use Cake\I18n\I18n;
I18n::locale('pl_PL');

//and/or

use Cake\I18n\Time; 
Time::$defaultLocale = 'pl-PL'; //and or
Time::setToStringFormat('YYYY-mm-dd HH:mm');//and or
Type::build('datetime')->useLocaleParser(false);//and or

None of code above helped. Does anyone have any idea how I can change the date format?

Answer 1

I guess you have been upgrading to CakePHP 3.2, otherwise you'd have seen in your config/bootstrap.php file that there are separate types for DATE, DATETIME and TIME type columns.

With CakePHP 3.2 the date type doesn't mape to Cake\I18n\Time anymore, but to \Cake\I18n\Date (or \Cake\I18n\FrozenDate when instructed to use immutable objects), and it needs to be configured separately, which is why changing the datetime type, or the \Cake\I18n\Time class config won't affect your DATE columns.

To configure formatting for the latter, use the \Cake\I18n\Date and/or \Cake\I18n\FrozenDate class and the date type. In your bootstrap, you could do something like

ini_set('intl.default_locale', 'pl_PL');

// ...

Cake\I18n\Date::setToStringFormat('yyyy-MM-dd');
Cake\I18n\FrozenDate::setToStringFormat('yyyy-MM-dd');

\Cake\Database\Type::build('date')
    ->useImmutable()
    ->useLocaleParser()
    ->setLocaleFormat('yyyy-MM-dd');

That would override the defaults that are being applied when using the pl_PL locale. Note that you should use yyyy instead of YYYY (as the latter defines the week-numbering year), and MM instead of mm (as the latter defines minutes).

See http://www.icu-project.org/apiref/icu4c/classSimpleDateFormat.html#details for the format used by the intl formatter that CakePHP uses internally.

Also note that there's also \Cake\I18n\Date::$wordFormat and \Cake\I18n\Date:$niceFormat which you may want to change too.

Answer 2

after a lot of searching I found.

In the config/app.php under the 'App' => []

change

'defaultLocale' => env('APP_DEFAULT_LOCALE', 'us_US'),

to

'defaultLocale' => env('APP_DEFAULT_LOCALE', 'pl_PL'),

and all your date will change to your formatting. because in config/boostrap.php it read

ini_set('intl.default_locale', Configure::read('App.defaultLocale'));

end in the cake\I18n FrozenDate it set to

protected static $_toStringFormat = [IntlDateFormatter::SHORT, -1];

Paste this code in this file config/site.php:

return [
 'Site' => [      
        'CakeDateFormat' => 'Y-M-d',
        'DatePickerFormat' => 'mm/dd/yyyy',
        'CakeDateFormatForView' => 'm/d/Y',        
    ]
]

Use this date format in controller:

use Cake\I18n\Time;

$this->request->data['date'] =Time::parseDate($this->request->data['date'], Configure::read('Site.CakeDateFormat'));

Set the date format according to your needs in CakeDateFormat.
