Currency changer ?

[Dez]

Thanks again Spike - is there any way of doing that globally somehow please ? It's just that there can sometimes be up to about 60 different locations on the website where the different euro figures will be displayed and often change as well.

Any help appreciated.

Dez.

[spikeZ]

sadly not looks like you have a bit of work to do Dez! (it is only one word after all!)

[Dez]

The work isn't the issue really, it's knowing how and where to apply the changes.

Is :

$number = '14,637.48';
echo round($number);
// will give 14,637

Supposed to go in the index.php file ? perhaps within the code below ?

<table cellpadding="0" cellspacing="0" width="660">
<tr>
<td width="50">&nbsp;</td>
<td>The current price, in euros, on the right :&nbsp; 1&euro;<br>
<br>
The equivalent price, in US dollars, automatically appearing to the right:&nbsp;<?=docurconversion(1,"USD")?> <br>
<br>
The equivalent price, in UK pounds, automatically appearing to the right:&nbsp;<?=docurconversion(1,"GBP")?> <br>
&nbsp;</td>
</tr>
</table>

I also have 3 other files that php_daemon kindly provided, should that code go in one of them instead please ?

Any help appreciated.

Dez.

There is the function docurconversion in index.php, to round the number change it to:

function docurconversion($val, $key)
{
    global $conversion_rates;

    if($conversion_rates[$key])
    {
        #$newfigure = number_format($val * $conversion_rates[$key]['rate'], 2, '.', ',');
        $newfigure = round($val * $conversion_rates[$key]['rate']);
        
        return "{$conversion_rates[$key]['label']}{$newfigure} ";
    }else return "";
}

[Dez]

That's very much appreciated Spike - I'm very new to all this malarkey - so the help from you good guys here has been really helpful.

One last thing - is there a quick, easy way to get the comma for the thousands at all please ?

To turn this :
£215462

Into this :
£215,462

All the best.

Dez.

[spikeZ]

That's what the original line in the function should have done....

 $newfigure = number_format($val * $conversion_rates[$key]['rate'], 2, '.', ',') 

I take it it didn't for some reason?

[Dez]

I had a feeling it should, but nope - it definitely doesn't do it :

All the best.

Dez.

[php_daemon]

Replace the said line with this:

$newfigure = number_format($val * $conversion_rates[$key]['rate'], 0, '.', ','); 

Basically I just changed the second param from 2 to 0, which is the decimals. So you don't need to use the round() function either.

It should do the job.

[Dez]

Many thanks to you php_daemon and to you Spike - all now complete.

The help from you both, and from Kevin earlier in the thread has been very much appreciated.

Dez.

[php_daemon]

You are very welcome.

[spikeZ]

Basically I just changed the second param from 2 to 0, which is the decimals. So you don't need to use the round() function either.

It should do the job.

That'll teach me to read the lines properly

Glad it's working

[Dez]

That'll teach me to read the lines properly

Glad it's working

I'm just glad that you and php_daemon stepped in when you did


All solved.

Dez.

[spikeZ]

this:

Current price, in euros, on the right:  11,493€

The equivalent price, in UK pounds:: £7,947 

The equivalent price, in US dollars: $14,621 
 


 	Current price, in euros, on the right :  311,586€

The equivalent price, in UK pounds: £215,462 

The equivalent price, in US dollars: $396,400

Why?

[Dez]

Problem all solved - there's some great helpful people here - long live sitepoint forums

Using all of the code that has been kindly given in this thread, is there any way of the 4 rates on the page below automatically updating itself, rounding up or down to the nearest figure, so that there's only ever a maximum of 2 digits after the dot please ?

http://www.130605.com/currency_rates/

Code on that page :

<?php
include "config.php";

$conversion_rates = array();
$handle = @fopen($ratesfile, "r");
if ($handle)
{
while (!feof($handle))
{
$buffer = fgets($handle, 4096);
$pieces = explode(":", $buffer);
$key = $pieces[0];
$conversion_rates[$key]['label'] = $pieces[1];
$conversion_rates[$key]['rate'] = $pieces[2];
}
fclose($handle);
}

function docurconversion($val, $key)
{
global $conversion_rates;

if($conversion_rates[$key])
{
$newfigure = number_format($val * $conversion_rates[$key]['rate'], 0, '.', ',');
return "{$conversion_rates[$key]['label']}{$newfigure} ";
}else return "";
}
?>

Hi Dez,
theoretically it should already do that using number_format and I cant tell what's happening on your page as there are no figures!

You can also have a look at money_format as another alternative.

Spike

[Dez]

Thanks for the quick response Spike. The figures on the left of the page are the static ones and trying to get the relevant figures to appear on the right.

http://www.130605.com/currency_rates/

All the best.

[Dez]

Just been trying to solve this. Have added some more code - <?=docurconversion(1,"GBP")?> but still no joy ?

Have run a cron job on converter.php as mentioned before in this thread.

Any help much appreciated.

Is it best to start another thread ? This thread is still about currency conversions using php, but my last request is slightly different to the one that started it. I don't want to upset any netiquette on here and I definitely want to stay on the good side of the really helpful people here.

Any help appreciated.

hi
this script i code it for a company it will convert the price from New Zealand Dollar to what ever depend on the user IP

you can modify it in the way you like...

that class i am using here is just for the user IP.

thanks

<?php


/*

function convert_price($theAmount)


{


// include the class


require_once('includes/i2m.class.php');





// call the class ip2more


$i2m = new ip2more();





// vars for the currency, currency code, amount


$theCurrency = $i2m->country['currency'];


$theCurrency_code = $i2m->country['currency_code'] ;





// if the amount is not number view error for webmaster


// stop the function


if (is_numeric ( $theAmount ) == false )


{


print "<div style='color:red'>Webmaster check this product price, it is contain string(s).</div>";


return;


}


else


{


// if the user ip is unkown


// stop the function


// only the NZ price will be displayed


if($theCurrency_code == 'UNKOWN')


{


return;


}


else


{


// if the user not in NZ convert

{

I've put it all together:

1. I've modified converter.php. First of all I took took out configuration block to config.php as it's needed everywhere the conversion is used. Secondly, I've modified docurconversion() so it's more flexible to use.

2. I've uploaded converter.php and config.php to my public_html. I've created rateslist.php (in public_html) and set it's permissions to 0777.

3. I've edited index.php to do the conversion.

I attached all of the files, too much to post here.

Note that you need to run converter.php before you can use the conversion. You should set up the cron job to run it daily.

Hope this helps.

Ok, I know it's been a while, but had a feeling you were all missing me No seriously, I've been picking this project up every few months and having a go at it for a few days, not being successful and then trying again a few months later when I had another chance - well, I finally had a big chance yesterday and today, and have come across a problem, as mentioned before, there's about 100 files (that are in 100 folders), that need to get the info from the special currency code files, now if I sit all of the files that PHP Daemon kindly setup for me, into every one of the 100 folders, they all work ok, but I didn't really want to do that and have 100 cron jobs going off 2-3 times day as well.

It would be great if all 100 files, just pointed to the one location for the files, (ideally, a folder called currency which had all of the relevant currency files in there) - is that possible please ?

Any help appreciated.

It's probably to do with absolute referencing as opposed to relative, but not sure where to make those changes. I don't mind paying a small amount if needs be.
