If your shop offers more than one currency, you need thiscontribution. With excahnge rates changing daily, at times, it is important to keep them up-to-date. Many, if not most, shop owners are not aware that this needs to be done. This contribution can be ran as a cron job or semi-automatically and will handle the updates for you. The existing Update Currencies contribution uses an external site that has changed their policy which means the updates may not always work. It also uses code that will prevent cron jobs from working on all servers. This contribution uses changed code and the same sites that oscommerce has always used so those problems should not occur.

i've given it a shot, but there seems to e a problem. roughly 1 in 5 (but random) currencies do not update?

it's a problem with the servers. XE does not work at all anymore (they charge for it these days) and oanda seems to be giving in too.

anyone know of any other servers that can be used?

[Jack_mcs]

That was the reason I wrote it using those servers. My site upgrades all currencies every night without any failures but another that I installed this script into will upgrade some currencies on some tries and others at others. I can only guess that it is a busy server issue. All of the online services I checked are wanting subscriptions to be made. While some are free, even onanda, it makes setting up a contribution like this impossible. If anyone knows of a reliable, free site, please let me know and I will add it to the code. In the meantime, I suggest you use the email option in the script and monitor the updates. You may find that all of the currencies get updated - just not everytime.

i've just set my cron to run every hour... with 24 tries per day it's bound to get them all right at some point in 24 hours!!!! although that's probably what caused this issue in the first place... too many sites updating too often.

I've found a few feeds you might want to look into. I've also foun a free API that looks REALLY useful:

http://xurrency.com/api

Check it out: if it's accurate and reliable it'd be really simple to use.


As for XML feeds:
The first is the European Central Bank, so uses the EUR as base rate (simple calculation can convert this to whatever):
http://www.ecb.int/stats/eurofxref/eurofxref-daily.xml

Another website, currencysource.com, seems quite useful, though they only allow you to check each currency once every 15 minutes and don't update it at weekends (though for the most part forex doesn't chnage at weekends, as its only Australia that really trades on our Sundays, and a few weirdos in Claifornia trading on Saturday mornings...):
http://www.currencysource.com/rss_currencyexchangerates.html

Don't know much about this one, just where it is, but it's especially useful as it doesn't use only one base rate:
http://www.webservicex.net/CurrencyConvert...;ToCurrency=GBP
obviously GBP and USD would be replaced with variables to get any currency you want...

Bank of Canada (so CAD is only base rat available):
http://www.bankofcanada.ca/en/rates/rss_fx.html

Thanks for the links. I'll test them out at some point.

Good evening

I installed your contribution and set up a cron job via cpanel and set the permission to 755 on the file and now this is what i am getting

any help would be appreciated

That isn't a problem with the contribution. It is failing before it even loads the file. My guess is that either the file was corrupted when uploaded or your server is setup somehow to prevent it from working. If the script runs when ran manually, http://yoursite.com/admin/auto_update_currencies.php, then the problem is with cron and you will need to talk to your host. If it fails the same way, then try replacing the script.

It looks like it isn't executing it as PHP... try entering this in the cron box:

php /home/digitalh/public_html/admin/auto_update_currencies.php

I'm guessing that you haven't got the php bit at the front [img]http://forums.oscommerce.com/style_emoticons/default/smile.gif[/img]

[TOG]

Hey Guys, I've done the installation and set the Cronjob but get the following result:

/bin/sh: -c: line 0: syntax error near unexpected token `newline'
/bin/sh: -c: line 0: `/home/httpd/cgi-bin/php4 <auto_update_currencies.php>'

My ISP has given me the following info:

1. To run a PHP 4 script. use the following: "/home/httpd/cgi-bin/php4 <filename>"
2. To run a PHP 5 script. use the following: "/home/httpd/cgi-bin/php5 <filename>"
3. To run a bash script, use the following: "/bin/bash <filename>"


This is the Cronjob command I used:

/home/httpd/cgi-bin/php4 <auto_update_currencies.php>


Can you help me with this error?

(I'm not too clued-up, so be gentle please)
Regards,
Leon

You have to give it the path to the file. Go to admin->modules and the full path will be listed on the page. Copy that and change it so it ends in admin/auto_update_currencies.php.

Thanks Jack,

(My domain is www.leon.co.za)

I'm now trying this:
/home/httpd/cgi-bin/php4/leon/catalog/admin/auto_update_currencies.php

and getting this:
/tmp/cron_run_command_leon.sh: line 3: /home/httpd/cgi-bin/php4/leon/catalog/admin/auto_update_currencies.php: Not a directory

Or trying this:
/home/httpd/cgi-bin/php4 <leon/catalog/admin/auto_update_currencies.php>

I'm getting this:
/tmp/cron_run_command_leon.sh: line 3: syntax error near unexpected token `newline'
/tmp/cron_run_command_leon.sh: line 3: `/home/httpd/cgi-bin/php4 <leon/catalog/admin/auto_update_currencies.php>'

Can't figure it out...

Appretiating your help!

[Jack_mcs]

The usual structure is
"path to php" "space" "path to file"
Your host told you the path to php:
/home/httpd/cgi-bin/php4
so add a space after it and place the full path
/home/httpd/cgi-bin/php4     /home/leon/catalog/admin/auto_update_currencies.php

I don't know that the second part is correct. As mentioned, you have to get that from the admin section. If it isn't correct, then you need to ask your host. That's what they are there for.

A newversion has been uploaded. The following has been change:

- Reversed order of servers being checked since xe.com seems to provide quicker updates. These are settable in the file
so they can be switched back if desired.
- Added date checked code so that the updates are not attempted if an update has already been done within a certain number of hours. That number is settable in the file.

Jack

In this new version, is the date checked only set if the update was succesful (and not when the update runs, but doesn't work)?

If so, great work, solves a lot of problems!

Thanks.

[Jack_mcs]

I'm not sure I understand your question but here is what it does. When the script is ran, it reads in the last update value from the database for each currency. If the last update is more than the time value option in the file, the outdated currecny is checked. If it is successfully updated, the database last update value is updated. Otherwise it is not changed so the next time the script is ran, that currecny will be checked again.

I just realized there is a slight mistake in the code. The line in the file that reads

return $ndays;

should be changed to

return $nhours;

Maybe this is not related to this contribution but i have this problem -> Warning: file() [function.file]: URL file-access is disabled in the server configuration in /nfs/c03/h04/mnt/56589/domains/html/admin/includes/functions/localization.php on line 14

This what I see every time I click on update and this is the same problem i get from the cron job.
Any idea?
