Hi,

Try to add that code:

Code:

function check(&$field,&$value,$oldvalue){
		$value = JFactory::getDate()->format($value);
		return true;
	}

before the code:

Code:

function showfield($viewObj, $namekey, $row) {
		if( isset( $row->$namekey)) {
			$date_format = !empty( $this->field_options['format']) ? $this->field_options['format'] : '%Y-%m-%d %H:%M:%S';
			return hikashop_getDate( $row->$namekey, $date_format);
		}
		return '';
	}

in the file administrator/components/com_hikashop/classes/field.php

I added your code in that file, but i don't need call check function in here or another place? Where this function should be called?

Hi,

That's what this function is supposed to do.
The check function is called automatically by the system before storing the value of a custom field of that type so that it can verify the validity of the value.

Then try adding this code instead:

Code:

function check(&$field,&$value,$oldvalue){
		$date = explode('/',$value);
		$value = implode('/',$this->gregorian_to_jalali($date[0],$date[1],$date[2]));
		return true;
	}
function div($a,$b) { 
    return (int) ($a / $b); 
} 
 
function gregorian_to_jalali ($g_y, $g_m, $g_d,$str=false) 
{ 
    $g_days_in_month = array(31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31); 
    $j_days_in_month = array(31, 31, 31, 31, 31, 31, 30, 30, 30, 30, 30, 29); 
 
  
   $gy = $g_y-1600; 
   $gm = $g_m-1; 
   $gd = $g_d-1; 
 
   $g_day_no = 365*$gy+$this->div($gy+3,4)-$this->div($gy+99,100)+$this->div($gy+399,400); 
 
   for ($i=0; $i < $gm; ++$i) 
      $g_day_no += $g_days_in_month[$i]; 
   if ($gm>1 && (($gy%4==0 && $gy%100!=0) || ($gy%400==0))) 
      /* leap and after Feb */ 
      $g_day_no++; 
   $g_day_no += $gd; 
 
   $j_day_no = $g_day_no-79; 
 
   $j_np = $this->div($j_day_no, 12053); /* 12053 = 365*33 + 32/4 */ 
   $j_day_no = $j_day_no % 12053; 
 
   $jy = 979+33*$j_np+4*$this->div($j_day_no,1461); /* 1461 = 365*4 + 4/4 */ 
 
   $j_day_no %= 1461; 
 
   if ($j_day_no >= 366) { 
      $jy += $this->div($j_day_no-1, 365); 
      $j_day_no = ($j_day_no-1)%365; 
   } 
 
   for ($i = 0; $i < 11 && $j_day_no >= $j_days_in_month[$i]; ++$i) 
      $j_day_no -= $j_days_in_month[$i]; 
   $jm = $i+1; 
   $jd = $j_day_no+1; 
 if($str) return $jy.'/'.$jm.'/'.$jd ;
   return array($jy, $jm, $jd); 
}
