Change admin panel date system

[Azerilatama]

Hi

I want to change the date system of ojs 3.0.2 to my local date system (jalali).
i successfully change the public face of site date system with help of blow topic by change in smarty date_format function.
but i can not change the date system in admin panel. can any body help me.

Jalali date(persian date)

hi I want to convert date of OJS system from Gregorian to Jalali.I am php programer can anyone help me how to do this? my OJS version is 2.4.6 thank you

i suppose it should be some sort of core function in the ojs for managing date, but i cant find any thing.

so finally I solved my problem by hard coding.
I manually changed the code which responsible for returning time string(date and strftime). the only drawback is that, in case of update they should be editing again.

Hi @asmecher,

Sure. it’s the benefits of open source project and support forum.
Unforgettably i am not so familiar with github , so I only explain what i done.

At first sorry for poor English

at first I define a new class in core class folder => “/lib/pkp/classes/core” (which obsoletelly it can be any where else) to define the date function (date and strftime) which produce different output respect to local:

import(“classes.i18n.AppLocale”);
class DateManagment
{

public static function date($format, $stamp = false)
{

    $stamp = ($stamp !== false) ? $stamp : time();
    if(AppLocale::getLocale() == "fa_IR")
    {
        return date based on my locale
    }

    return date($format, $stamp);
}

public static function strftime($format, $stamp = false)
{
    $stamp    = ($stamp !== false) ? $stamp : time();

    if(AppLocale::getLocale() == "fa_IR")
    {
        return strftime based on my locale
    }

    return strftime($format, $stamp);
}

}

now i should change ojs code to perform my date and strftime function.
As I found the class which has the word “CellProveder” inside their name (like QueriesGridCellProvider.inc.php) are responsible to admin panel data (may be a crude guess but it work in this case) so i change every date and strftime function inside them to run my functions (from date and strftime to DateManagment::date and DateManagment::strftime). and also change the strftime function inside “/lib/pkp/lib/vendor/smarty/smarty/libs/plugins/modifier.date_format.php” file which is responsible to date strings of public face of site.

the only thing now i should change is the datepicker which used in “create a new announcement” section, which i worked on it. in the case of success I would be happy to explain it (with this awful English )

finally successfully update datepicker to my local calendar (jalali), lets see what i done.

fortunately the jquery-ui datepicker (which used in ojs) support locale so easily by adding the flowing lines to the registerJSLibrary function of the “/lib/pkp/classes/template/PKPTemplateManager.inc.php” file I said ojs to load the locale file of datepicker.

$datepickerLocalePath = ‘/lib/pkp/lib/components/jquery-ui/ui/i18n/datepicker-’ .strtolower(substr(AppLocale::getLocale(), 0, 2)).‘.js’;
$this->addJavaScript(‘datepickerlocal’, $baseUrl . $datepickerLocalePath , array(‘priority’ => STYLE_SEQUENCE_CORE,‘contexts’ => ‘backend’));

and i update that javascript file in order to work based on my calendar.

but there is a very important point which should be considered. when i change the calendar, becouse the ojs store the date string, it will store the date base on my calendar system, and if i change the language to English, the ojs will confused with these date string. so i should convert date to gregorian before store.

thanks again from the ojs:
If ojs find a .datepicker in tpl the code adds (form/textInput.tpl) a new hidden field with the id = [original-element-id]-altField, and its value has been posted as the date string.
so in the datepicker javascript i update the “_updateAlternate” function to store Gregorian date in the altfield. and finally change the datepicker initialization function (_attachDatepicker) to also call the _updateAlternate function at the beginning of datepicker initialization.
