Local calendar

[voltan]

Hi

support local calendar is to important for us. and whit php 5.3 and intl its very easy . just need one line code :

$fmt = new IntlDateFormatter("fa_IR@calendar=persian", IntlDateFormatter::FULL, IntlDateFormatter::FULL, 'Asia/Tehran', IntlDateFormatter::TRADITIONAL);
return $fmt->format($date);

But I don't know what is the best way for use it in PI. We need general date manager function for support all languages / calendars. At this moment we use date function for make date. we need change / update it.

date('Y-m-d H:i:s', $data['update'])

And use it all codes for example as i18n/View/Helper/DateFormat.php in templates and rewrite it for support local calendar

And if support in controller is very good for ajax functions and json outputs

I am working on it. Can you give some use cases?

[voltan]

I'll send live pi example here in next two hour after finish server config

[voltan]

I add this line in template ( just for test )

$fmt = new IntlDateFormatter("fa_IR@calendar=persian", IntlDateFormatter::MEDIUM, IntlDateFormatter::SHORT, 'Asia/Tehran', IntlDateFormatter::TRADITIONAL);

And use this function for make date

$fmt->format(intval($message['create']));

And template is here : https://github.com/taiwen/voltan/blob/master/usr/module/sms/template/front/list.phtml

I add some changes in date format and get image for result :

1- Persian calendar whit Persian text

$fmt = new IntlDateFormatter("fa_IR@calendar=persian", IntlDateFormatter::MEDIUM, IntlDateFormatter::SHORT, 'Asia/Tehran', IntlDateFormatter::TRADITIONAL);

2- Persian calendar whit English text

$fmt = new IntlDateFormatter("en_US@calendar=persian", IntlDateFormatter::MEDIUM, IntlDateFormatter::SHORT, 'Asia/Tehran', IntlDateFormatter::TRADITIONAL);

3- Gregorian calendar whit English text ( default )

$fmt = new IntlDateFormatter("en_US", IntlDateFormatter::MEDIUM, IntlDateFormatter::SHORT, 'Asia/Tehran', IntlDateFormatter::TRADITIONAL);

4- Gregorian calendar whit Persian text

$fmt = new IntlDateFormatter("fa_IR", IntlDateFormatter::MEDIUM, IntlDateFormatter::SHORT, 'Asia/Tehran', IntlDateFormatter::TRADITIONAL);

For use cases, it need for all date outputs , I think for each website / language we need some settings. Like :

• Time Zone ( it exist )
• Language ( it exist )
• Calendar
• Date format : MEDIUM / SHORT ...
• Time format

And mvc plugin / view helper / i18n class, for use it in all controllers / template / other parts

[taiwen]

We also need use cases for NumberFormatter

[voltan]

I test this helper in i18n : http://framework.zend.com/manual/2.0/en/modules/zend.i18n.view.helpers.html#numberformat-helper

For Persian / Arabic language it has good support ( here for example : http://www.payamakyab.com/ ), just we need tools for set NumberFormatter and local

Thank you very much, It work for me fine , just two points : 1- It possible to update pi module codes and use _date() functions 2- I am not sure, But perhaps it bug, when I change timetype and datetype its not work, I'll test on other machine

[taiwen]

Can we use _date() in Pi modules? Kind of complicated:

• Intl extension is not installed in PHP by default thus intlDateFormatter/NumberFormatter is not natively available.
• In case _date()/_intl() is not available, _date() is not able to transform to date() directly.

A tricky solution is:

    if (_intl()) {
        // Use _date();
    } else {
        // Use date();
    }

[voltan]

I think we need date standard on all modules, if any one change calendar or date format , if php extensions installed use that. and if not installed use date()

[taiwen]

The problem is that arguments are different

[voltan]

Perhaps whit this edit is solve :

    /**
     * Locale-dependent formatting/parsing of date-time using pattern strings and/or canned patterns
     *
     * @param array|string|null $locale
     * @param int|null $datetype
     * @param int|null $timetype
     * @param string|null $timezone
     * @param int|string|null $calendar
     * @param string|null $pattern
     * @return string
     */
    function _date($value, $locale = null, $datetype = null, $timetype = null, $timezone = null, $calendar = null, $pattern = null)
    {
        if (!_intl()) {
               $pattern = Pi::config('date_pattern', 'intl');
            return date($value, $pattern);
        }

        $formatter = Pi::service('i18n')->getDateFormatter($locale, $datetype, $timetype, $timezone, $calendar, $pattern);
        $result = $formatter->format($value);

        return $result;
    }

Big thanks for add this option, All of our problems for localization solved
