Hi there,

If you want to update your store in EU with the European Central Bank Currency please see below.

This was made in Prestashop svn version 1.4.0.12 (7-Feb-2011)

In the folder: "classes"
the file: Currency.php

Go to line 255 (I commented with // the original line. The line above is what I you should have).

WARNING: Only use this if you have the EUR currency as default.

   public function refreshCurrency($data, $isoCodeSource, $defaultCurrency)
   {
       if ($this->iso_code != $isoCodeSource)
       {
           /* Seeking for rate in feed */
//            foreach ($data->currency AS $obj)
           foreach ($data->Cube->Cube->Cube AS $obj)
//            if ($this->iso_code == strval($obj['iso_code']))
           if ($this->iso_code == strval($obj['currency']))
           $this->conversion_rate = round((float)($obj['rate']) /  $defaultCurrency->conversion_rate, 6);
       }
       else
       {
           /* If currency is like isoCodeSource, setting it to default conversion rate */
           $this->conversion_rate = round(1 / (float)($defaultCurrency->conversion_rate), 6);
       }
       $this->update();
   }

   static public function refreshCurrenciesGetDefault($data, $isoCodeSource, $idCurrency)
   {
       $defaultCurrency = new Currency($idCurrency);

       /* Change defaultCurrency rate if not as currency of feed source */
       if ($defaultCurrency->iso_code != $isoCodeSource)
//            foreach ($data->currency AS $obj)
           foreach ($data->Cube->Cube->Cube AS $obj)
//            if ($defaultCurrency->iso_code == strval($obj['iso_code']))
           if ($defaultCurrency->iso_code == strval($obj['currency']))
           $defaultCurrency->conversion_rate = round((float)($obj['rate']), 6);
       return $defaultCurrency;
   }

   static public function refreshCurrencies()
   {
//        if (!$feed = @simplexml_load_file('http://www.prestashop.com/xml/currencies.xml'))
       if (!$feed = @simplexml_load_file('http://www.ecb.europa.eu/stats/eurofxref/eurofxref-daily.xml'))
           return Tools::displayError('Cannot parse feed!');
       if (!$defaultCurrency = (int)(Configuration::get('PS_CURRENCY_DEFAULT')))
           return Tools::displayError('No default currency!');
//        $isoCodeSource = strval($feed->source['iso_code']);
       $isoCodeSource = 'EUR';
       $currencies = self::getCurrencies(true);
//        $defaultCurrency = self::refreshCurrenciesGetDefault($feed->list, $isoCodeSource, $defaultCurrency);
       $defaultCurrency = self::refreshCurrenciesGetDefault($feed, $isoCodeSource, $defaultCurrency);
       foreach ($currencies as $currency)
           if ($currency->iso_code != $defaultCurrency->iso_code)
//                $currency->refreshCurrency($feed->list, $isoCodeSource, $defaultCurrency);
               $currency->refreshCurrency($feed, $isoCodeSource, $defaultCurrency);
   }



Ooooooppss. It wasn't very easy but thats it. Log in in your control panel and go to "Payment"->"Currencies" and click "Update currency rates"

In attach you have the file for Prestashop 1.4.0.12.
Download it and save it to your "classes" folder in your root folder (rename your currency.php to currency.old if you want and try it first).

A hug for everyone. ;-)

Hi there again,

For the Prestashop version 1.3.6.0 like above:

WARNING: Use this only if your default currency is EUR.

Go to your "classes" folder on your root, and then open "currency.php". On line 188 you should have this (the original line I have commented it with // and above is my line):

   public function refreshCurrency($data, $isoCodeSource, $defaultCurrency)
   {
       if ($this->iso_code != $isoCodeSource)
       {
           /* Seeking for rate in feed */
//            foreach ($data->currency AS $obj)
           foreach ($data->Cube->Cube->Cube AS $obj)
//                if ($this->iso_code == strval($obj['iso_code']))
               if ($this->iso_code == strval($obj['currency']))
                   $this->conversion_rate = round(floatval($obj['rate']) /  $defaultCurrency->conversion_rate, 6);
       }
       else
       {
           /* If currency is like isoCodeSource, setting it to default conversion rate */
           $this->conversion_rate = round(1 / floatval($defaultCurrency->conversion_rate), 6);
       }
       $this->update();
   }

   static public function refreshCurrenciesGetDefault($data, $isoCodeSource, $idCurrency)
   {
       $defaultCurrency = new Currency($idCurrency);

       /* Change defaultCurrency rate if not as currency of feed source */
       if ($defaultCurrency->iso_code != $isoCodeSource)
//            foreach ($data->currency AS $obj)
           foreach ($data->Cube->Cube->Cube AS $obj)
//                if ($defaultCurrency->iso_code == strval($obj['iso_code']))
               if ($defaultCurrency->iso_code == strval($obj['currency']))
                   $defaultCurrency->conversion_rate = round(floatval($obj['rate']), 6);
       return $defaultCurrency;
   }

   static public function refreshCurrencies()
   {
//        if (!$feed = @simplexml_load_file('http://www.prestashop.com/xml/currencies.xml'))
       if (!$feed = @simplexml_load_file('http://www.ecb.europa.eu/stats/eurofxref/eurofxref-daily.xml'))
           return Tools::displayError('Cannot parse feed!');
       if (!$defaultCurrency = intval(Configuration::get('PS_CURRENCY_DEFAULT')))
           return Tools::displayError('No default currency!');
//        $isoCodeSource = strval($feed->source['iso_code']);
       $isoCodeSource = 'EUR';
       $currencies = self::getCurrencies(true);
//        $defaultCurrency = self::refreshCurrenciesGetDefault($feed->list, $isoCodeSource, $defaultCurrency);
       $defaultCurrency = self::refreshCurrenciesGetDefault($feed, $isoCodeSource, $defaultCurrency);
       foreach ($currencies as $currency)
           if ($currency->iso_code != $defaultCurrency->iso_code)
//                $currency->refreshCurrency($feed->list, $isoCodeSource, $defaultCurrency);
               $currency->refreshCurrency($feed, $isoCodeSource, $defaultCurrency);
   }



The code is the same. The difference is that in one file is at line 188 and the PS 1.4 is in line 255.

Attached is the file for Prestashop 1.3.6.0 that you can download and put in /classes folder (rename your other file to currency.old if you want).

A hug for everyone!

Hi there again,

 

If you still want to update your store in EU with the European Central Bank Currency please see below.

 

This was made in Prestashop 1.4.7.0 (17-Mar-2012)

Folder: classes

File: Currency.php

 

 

Go to line 262 (I commented with // the original line. The line above is what you should have).

 

WARNING: Only use this if you have the EUR currency as default.

 

public function refreshCurrency($data, $isoCodeSource, $defaultCurrency)
{
	// fetch the conversion rate of the default currency
	$conversion_rate = 1;
	if ($defaultCurrency->iso_code != $isoCodeSource)
	{
//			foreach ($data->currency AS $currency)
		foreach ($data->Cube->Cube->Cube AS $currency)
//				if ($currency['iso_code'] == $defaultCurrency->iso_code)
			if ($currency['currency'] == $defaultCurrency->iso_code)
			{
				$conversion_rate = round((float)$currency['rate'], 6);
				break;
			}
	}

	if ($defaultCurrency->iso_code == $this->iso_code)
		$this->conversion_rate = 1;
	else
	{
		if ($this->iso_code == $isoCodeSource)
			$rate = 1;
		else
		{
//				foreach ($data->currency AS $obj)
			foreach ($data->Cube->Cube->Cube AS $obj)
//					if ($this->iso_code == strval($obj['iso_code']))
				if ($this->iso_code == strval($obj['currency']))
				{
					$rate = (float) $obj['rate'];
					break;
				}
		}

		$this->conversion_rate = round($rate /  $conversion_rate, 6);
	}
	$this->update();
}

/**
* @deprecated
**/
public static function refreshCurrenciesGetDefault($data, $isoCodeSource, $idCurrency)
{
	Tools::displayAsDeprecated();

	$defaultCurrency = new Currency($idCurrency);

	/* Change defaultCurrency rate if not as currency of feed source */
	if ($defaultCurrency->iso_code != $isoCodeSource)
		foreach ($data->currency AS $obj)
			if ($defaultCurrency->iso_code == strval($obj['iso_code']))
				$defaultCurrency->conversion_rate = round((float)($obj['rate']), 6);

	return $defaultCurrency;
}

public static function getDefaultCurrency()
{
	$id_currency = (int)Configuration::get('PS_CURRENCY_DEFAULT');
	if ($id_currency == 0)
		return false;

	return new Currency($id_currency);
}

public static function refreshCurrencies()
{

	$currencies = self::getCurrencies(true);
	foreach ($currencies as $currency)
//			$currency->refreshCurrency($feed->list, $isoCodeSource, $default_currency);
		$currency->refreshCurrency($feed, $isoCodeSource, $default_currency);

}

 

If you want automatic update, you can create a cron job. (See my post from 17-Mar-2012)

First you create a file in your prestashop folder, called cron.php (Thanks Rocky. The original post is here.) with this:

<?php

include(dirname(__FILE__).'/config/config.inc.php');
include(dirname(__FILE__).'/classes/Currency.php');

if (isset($_GET['secure_key']) AND $_GET['secure_key'] === 'password')
  Currency::refreshCurrencies();

?>

NOTE: change 'password' to whatever you like. Ex: 'asdERWE#$343344'

 

Then try it first by calling the page, like this:

http://www.yourshop....asdERWE#$343344

 

If it works, then create a cron job in your cpanel (or other):

For every day, this: 0 0 * * *

The command should be like this: php /home3/myaccountname/public_html/myprestashopfolder/cron.php

 

If you have any doubts, just tell me! ;-)

 

See you and enjoy!

Hi there to everyone,

 

This is no more needed because the rates are identical (Prestashop changed).

Check the rates now, they are the same:

Prestashop currency rates

and the rates a European Central Bank at:

European Central Bank rates

 

Prestashop team told me they will be working on a cron job for this.

 

Thanks guys!

 

EDIT: in your admin folder the file is cron_currency_rates.php (See my post here from 17-Mar-2012)

for automatic update create a file in the root directory cron.php

with code:

 

<?php
include(dirname(__FILE__).'/config/config.inc.php');
include(dirname(__FILE__).'/classes/Currency.php');
if (isset($_GET['secure_key']) AND $_GET['secure_key'] === 'password')
  Currency::refreshCurrencies();
?>

 

change password as you like, for exampe 23Ab09Ce etc.

 

After that in your server control panel create a crontab with name for example Currency

and use file URL http://www.yoursite....php?secure_key=password

 

And set the time you want for automatic start of this file (all weekdays, all months, all days, chose the hours and minutes).

 

NB! Rates are usually updated by 3 p.m. C.E.T by Europen Central Bank

Hi everyone,

 

Thanks Jevgen but you don't need this anymore in version 1.4.7.0. You have a file called cron_currency_rates.php in your admin folder that has that configuration. If you want to see the link, go to your Backoffice -> Payment -> Currencies and a the bottom of the page you can see the link in "Automatically update currency rates".

Hi guys,

 

As the currency market is quiet volatile and it's hard to find a instant update feed, I would like to include in the update file a fonctions that add +0.009 to all currency. So it will balance the small differences that can be founded.

 

Anybody know where I can add this ?

I have expanded Jonadabe's solution, and wanted to share this for Prestashop v1.4.7. Where as his solution only works for EUR as the default currency, my solution will work for any currency as default.

 

/**
* Refresh the currency conversion rate
* The XML file define conversion rate for each from a default currency ($isoCodeSource).
*
* @param $data XML content which contains all the conversion rates
* @param $isoCodeSource The default currency used in the XML file
* @param $defaultCurrency The default currency object
*/
public function refreshCurrency($data, $isoCodeSource, $defaultCurrency)
{
	// fetch the conversion rate of the default currency
	$conversion_rate = 1;
	if ($defaultCurrency->iso_code != $isoCodeSource)
	{
		//foreach ($data->currency AS $currency)
		foreach ($data->Cube AS $currency)
			//if ($currency['iso_code'] == $defaultCurrency->iso_code)
			if ($currency['currency'] == $defaultCurrency->iso_code)
			{
				$conversion_rate = round((float)$currency['rate'], 6);
				break;
			}
	}

	if ($defaultCurrency->iso_code == $this->iso_code)
		$this->conversion_rate = 1;
	else
	{
		if ($this->iso_code == $isoCodeSource)
			$rate = 1;
		else
		{
			//foreach ($data->currency AS $obj)
			foreach ($data->Cube AS $obj)
			 // 	if ($this->iso_code == strval($obj['iso_code']))
				  if ($this->iso_code == strval($obj['currency']))
				{

			  $rate = (float) $obj['rate'];
					break;
				}
		}
			   $this->conversion_rate = round($rate / $conversion_rate, 6);
	}
	$this->update();
}

/**
* @deprecated
**/
public static function refreshCurrenciesGetDefault($data, $isoCodeSource, $idCurrency)
{
	Tools::displayAsDeprecated();

	$defaultCurrency = new Currency($idCurrency);

	/* Change defaultCurrency rate if not as currency of feed source */
	if ($defaultCurrency->iso_code != $isoCodeSource)
		//foreach ($data->currency AS $obj)
		foreach ($data->Cube AS $obj)
			//if ($defaultCurrency->iso_code == strval($obj['iso_code']))
			if ($defaultCurrency->iso_code == strval($obj['currency']))
				$defaultCurrency->conversion_rate = round((float)($obj['rate']), 6);

	return $defaultCurrency;
}

public static function getDefaultCurrency()
{
	$id_currency = (int)Configuration::get('PS_CURRENCY_DEFAULT');
	if ($id_currency == 0)
		return false;

	return new Currency($id_currency);
}

public static function refreshCurrencies()
{
			// Parse
//			  if (!$feed = Tools::simplexml_load_file('http://www.prestashop.com/xml/currencies.xml'))
			if (!$feed = Tools::simplexml_load_file('http://www.ecb.europa.eu/stats/eurofxref/eurofxref-daily.xml'))
					return Tools::displayError('Cannot parse feed.');

			// Default feed currency (EUR)
//			  $isoCodeSource = strval($feed->source['iso_code']);
			$isoCodeSource = 'EUR';

	if (!$default_currency = self::getDefaultCurrency())
		return Tools::displayError('No default currency');

	$currencies = self::getCurrencies(true);
	foreach ($currencies as $currency)

//			$currency->refreshCurrency($feed->list, $isoCodeSource, $default_currency);
	 $currency->refreshCurrency($feed->Cube[0]->Cube[0], $isoCodeSource, $default_currency);
}

 

@SebeyTRF

To achieve this functionality just change the line

$this->conversion_rate = round($rate / $conversion_rate, 6);

with

$this->conversion_rate = round($rate * 1.009 / $conversion_rate, 6); //Adding 0.009 to all currencies as requested by [b]SebeyTRF[/b]
