Auto Update Currencies

[Jack_mcs 772]

You can change that in the auto_update_currencies.php file, near the top. But you may want to just simulate a return instead of actually going to the site each time because if you visit it too much they may block your IP, at least for a while.

Sick of me yet???? :blush:

 

I think I have my code sorted so it works for what I asked earlier (posts #72 & #73) once I'm sure I'll post it up here just incase there is another person who needs that info....

 

Quick question though... Do you know how often you can access the exchange rates without getting blocked out??? is every hour too frequent?

[Jack_mcs 772]

No, I don't. Those sites probably have a TOS page though.

Thanks, I understand now. There's nothing written for that that I am aware of. You could try editing the admin/includes/functions/localization.php file and change

function quote_xe_currency($to, $from = DEFAULT_CURRENCY) {

to

function quote_xe_currency($from = DEFAULT_CURRENCY, $to) {

I haven't tried it but it would be my first guess. If it works, you would also have to change the function for oanda. If that doesn't work, then the code in the update section of currencies.php could be altered to figure out the exchange rate, once retrieved, and then alter the calculation so it uses the inverse. Good luck. :)

 

in case anyone wants to get the inverse value, this is how you do it...

function quote_xe_currency($from, $to = DEFAULT_CURRENCY) {

and,

function quote_oanda_currency($base, $code = DEFAULT_CURRENCY) {

Hello @@Jack_mcs I did the edit of the file and upload it to the admin directory, setup a cron job, but I don't know why its not working, I waited 48h and the exchange rate didn't changed.

Also I tried to run the script directly by browsing domain.com/admin/auto_update_currencies.php the page returned a blank page and the exchange rate didn't changed.

 

can you please help me ?

[Jack_mcs 772]

The page shouldn't be blank when you run it. That indicates a problem of some kind. If your site generates an error_log file in the admin directory, look at it to see if it shows any errors for this problem. You might also want to go over the installation to be sure you didn't miss something. And try going into admin->Localization->Currencies and clicking on the update currencies button. If that fails to work, then something on your server is blocking the connection.

[Psytanium 15]

the update currency button is working fine, currencies updated.

 

thats the code

anything wrong ?

[Jack_mcs 772]

If you are using around 2.3.3 (maybe before), that won't work. The database calls are different for those versions. I'll update this as soon as I can.

[Psytanium 15]

What versions are compatible ?

is there something i can do ?

[Jack_mcs 772]

It will work with any of the versions that don't use mysqli, which start around 2.3.3, I think. You can try replacing all instance of mysql in that file with mysqli. I haven't looked close enough at it to say if that will work or not but those calls are the problem. The correct fix, and what should have been done initially, is to include application_top and use the tep functions. That's the change I will make once I get to it.

n.b I have an extra quick and dirty line in there (if ($rate !=1){$rate=$rate*1.02;}) that adds 2% markup on the exchange rate as my payment processor adds that in as their premium over and above the bank rates.

 

edit: commented out that line but left it in there FYI

@@Jack_mcs, i have no idea why the cron jobs is not working. just a quick question

 

if a browse directly www.domain.com/admin/auto_update_currencies.php i should be asked to login?

[Jack_mcs 772]

If your admin is setup correctly, yes. Otherwise there is a big security hole in your admin.

[Psytanium 15]

i think you are right, there is a security problem, some phishing files.

how can i fix this issue ? just upgrading to the latest version ? or there is something else ?

 

thank you for your advice.

[Jack_mcs 772]

If you can get into your admin without logging in, it doesn't have anything to do with this addon. I suggest you first the security checker on my site since there may be more problems besides admin. Then create a new thread in the general forum asking for help in fixing the problems, if you need it. 

[Psytanium 15]

sry i get you wrong at first. yes if i run the url from a browser the page ask me to login. does this mean the cron jobs is running fine but have permission problem with the addon ?

that's what i have in the file :

require_once('includes/configure.php');
    require_once(DIR_WS_FUNCTIONS . 'localization.php');
     
    $link = mysqli_connect(DB_SERVER, DB_SERVER_USERNAME, DB_SERVER_PASSWORD,DB_DATABASE) or die("Unable to connect to database server!");

should i replace some variables ?

 

Cron jobs: /home/wood/public_html/admin/auto_update_currencies.php

[Jack_mcs 772]

That sounds like the code is not loading properly when ran from cron. I'll work on this as soon as I can, though that may be weeks. You could use the alternate method as mentioned in the install instructions.

[Psytanium 15]

this is the cronjob output i'm getting:

 

/usr/local/cpanel/bin/jailshell: /home/domain/public_html/backend/auto_update_currencies.php: Permission denied

 

any idea what could be the reason ?

 

I'm running osc 2.3.4

[Jack_mcs 772]

That is a server issue. The correct syntax for a cron job varies with the server. It might be that what you are using is wrong or that ownership of the admin is not set to user, or something like that. You will have to ask your host to take a look at it.

[Psytanium 15]

done and working.

Probably xe is using a new api link, i change in admin/includes/functions/localization.php

 

this:

$page = file('http://www.xe.net/ucc/convert.cgi?Amount=1&From=' . $from . '&To=' . $to);

to this:

$page = file('http://www.xe.com/currencyconverter/convert/?Amount=1&From='. $from . '&To=' . $to);

Now its working again.
