Auto Update Currencies

Hi there Jack

Here's the code I use on a 2.3.4 site - has the mysqli stuff in there

    foreach ($updated as $changed)
      $report .= $changed;

     {
      echo str_replace("\n", '<br>', $report);
    }

    
  }
  mysqli_close($link);
?>

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

 

Dirty trick there, so to make it even dirtier how to specify specific countries or currencies?

[Jack_mcs 930]

If you just want to update one particular currency, change this line

 $currency_query = mysqli_query($link,"select currencies_id, code, title, last_updated from currencies" ) or die(mysql_error());

to this

 $currency_query = mysqli_query($link,"select currencies_id, code, title, last_updated from currencies where currencies_id=XX " ) or die(mysql_error());

where xx is the ID of the currency you want to check.

Hi Peper - dirty trick? Moi?  :D

Hi,

 

I'm now getting the following error, any ideas please?

Warning: file_get_contents(http://www.xe.net/ucc/convert.cgi?Amount=1&From=GBP&To=EUR) [ function.file-get-contents]: failed to open stream: HTTP request failed! HTTP/1.0 400 Bad Request in /hosting/www/site.com/www/admin/includes/functions/localization.php on line 25

HTTP/1.1 404 Not Found in /hosting/www/site.com/www/admin/includes/functions/localization.php on line 14

 

Currencies are not being updated.

[Jack_mcs 930]

Alex - See the fix by Gary in this thread.

[mr_absinthe 0]

Thanks Jack :thumbsup:

[mr_absinthe 0]

Thank you again Jack for pointing me the right direction, after applying Gary's fix, there are no errors when updating currencies via admin, however still the same errors when running a cron and auto_update_currencies.php file. I guess that the file has to be also changed according to Gary's fix... Is it enough to change this?

from:

define('CURRENCY_SERVER_PRIMARY', 'oanda');

to:

define('CURRENCY_SERVER_PRIMARY', 'fixer');

most likely not, because currency update report is received by email with text Currencies for store updated on Tue Dec 13 8:56:56 2016, however when looking in admin, they are not updated (date doesn't match).

Edited December 13, 2016 by mr_absinthe

[Jack_mcs 930]

You should change both lines as mentioned in the fix.

[mr_absinthe 0]

Will do

[Jack_mcs 930]

A new version has been uploaded with these changes:

 

• Added code to account for changes in hours being over one day.
• Added an option and code to allow the update to be ran from admin instead of cron.
• Changed code to work with the fixer server.
• Changed code so date function returns hours instead of days.
• Changed php shortcut <?

Hoping someone can help.

 

I have been out of oscommerce and php too many years and really have lagged behind the times.

 

 

I have a friend running a 2.3.4 that was running this contrib, but only realised today errors in updating currencies as it was not updatred by the folks looking after it now!

 

PHP Version: 5.3.29 (Zend: 2.3.0)  Database: MySQL 5.5.54-cll

 

I have done the fixes on github to the relevant files - the manual update button on the currencies page works fine via the fixer server and have uploaded the latest version of this contrib so he can control it via his admin panel and I also tried it via crontab. 

 

However, it is throwing up an error:

 

"Fatal error: Call to undefined function tep_db_fetch_array() in /home/xxxxxxxx/public_html/backend/auto_update_currencies.php on line 36"

 

and for the life of me I cannot remember how to fix it.

 

Any help very much appreciated as always, as I am unable to spend much time on this as I have just undergone hand surgery and it is killing me!

That error refers to a standard function and it is saying the function is missing. The latest version of this addon checks for a server variable to determine if the code is ran by cron or not. It might be that that variable isn't set on your server, though it should be. Try editing the file and change this code

      require('includes/application_top.php');
  }

to this

  }
      require('includes/application_top.php');

I have just uploaded your latest auto_update_currencies addon, cannot run it because it was initially complaining about a missing date_diff function. I then source the function from ver 1.1 but updated the last line with the recommended change to " return $nhours". Now I'm getting the following error messages:

 

Warning: strtotime() expects parameter 1 to be string, object given in ~/admin/auto_update_currencies.php on line 29

Warning: strtotime() expects parameter 1 to be string, object given in ~/admin/auto_update_currencies.php on line 30

Fatal error: Call to a member function format() on a non-object in ~/admin/auto_update_currencies.php on line 98

 

Any idea what I may be doing wrong? ... 

[Jack_mcs 930]

Please try using V 1.2 and see if that helps.

[Psytanium 15]

Hi @@Jack_mcs, I replaced the old file with the new release Jan 2017, i got the Fatal error: Call to undefined function tep_db_query() error.

 

I did what you proposed, I move require('includes/application_top.php'); out of if statement.

 

I run the script directly from https://www.domain.com/admin/auto_update_currencies.php

 

Now the error is gone, but should i leave it like this ?

 

Thanks

[Jack_mcs 930]

It won't hurt to leave it like that as long as it runs. The script should be able to run from cron as well as manually. It both work, or if you only need one to work, then it's fine.

[ochikumb 0]

I have installed V1.2 and also gone into /admin/includes/filenames.php to update 'FILENAME_CURRENCIES' to 'auto_update_currencies.php'. 

 

When I try to open the currencies update from admin I get this error:

 

Fatal error: Call to undefined function date_diff() in /home/content/78/4534778/html/admin/auto_update_currencies.php on line 83

[ochikumb 0]

Also the auto_update_currencies.php opens with <?php  and I do not see where it ends with the ?> 

[Jack_mcs 930]

FILENAME_CURRENCIES and 'auto_update_currencies.php' are totally different items. If you want to change FILENAME_CURRENCIES it would be 'currencies.php' (apostrophes required).

Thanks Jack ... appreciate your help!

Hi Jack!

 

This is the email message I get from trying to run the cron job:

 

Fatal error</b>: Call to undefined function date_diff() in <b>/~/admin/auto_update_currencies.php</b> on line <b>83</b>

[Jack_mcs 930]

This version of the addon will only work for php versions of 5.3 or greater. If your server is using less than 5.3, then you will need to use an earlier version of the addon. Also, what about if you run it manually? Does it fail that way too?

 

If it fails by running it manually and your servers is using 5.3 or greater, please try this. In the admin/auto_update_currencies.php file, find

$interval = date_diff($date_begin,$date_end);

and change it to

 $interval = $date_begin->diff($date_end);

I haven't tested the above but I think it will work.

[ochikumb 0]

Thanks again Jack ... and yes the php version I have is 5.2.17 and therefore I'll try and use v1.1 addon. And yes even if you try and run it manually or with the change you have suggested above, the problem will still occur.

 

I will let you know how I go with v1.1 addon.

Hello Jack,

what could be the reason ?

<br />
<b>Warning</b>:  session_start(): Cannot send session cookie - headers already sent in <b>/home/user/public_html/admin/includes/functions/sessions.php</b> on line <b>98</b><br />
<br />
<b>Warning</b>:  session_start(): Cannot send session cache limiter - headers already sent in <b>/home/user/public_html/admin/includes/functions/sessions.php</b> on line <b>98</b><br />

thank :)

[Jack_mcs 930]

That is usually caused by an extra line. If line 98 in that file is the last one then remove the last ?>. If it isn't, then it would depend on the code.
