jonnystudent Posted March 19, 2012 Share Posted March 19, 2012 Hello all, I'm looking for some assistance with some code. I'm trying to put this to bed as it's driving me nuts. The Psuedo code for this would be to 1) Download the rates from the Yahoo API and declare my base rate to my foreign exchange. 2) Store an array of currencies to choose from to compare against the base currency. 3) I then GET the chosen currency and register it in a SESSION to be used on other pages. (I'm unsure if this is correct?) 4) I then calculate the Price of my product which is in GBP to the selected foreign currency. 5) Output the converted price anywhere on the page. My script takes GET values from the URL like so.. .com?c=EUR My code is like so.. 1) First I get the rates from the Yahoo API session_start(); $from = 'GBP'; $to = '$c'; $url = 'http://finance.yahoo.com/d/quotes.csv?e=.csv&f=sl1d1t1&s='. $from . $to .'=X'; $handle = @fopen($url, 'r'); if ($handle) { $result = fgets($handle, 4096); fclose($handle); } $allData = explode(',',$result); /* Get all the contents to an array */ $PoundValue = $allData[1]; 2) Then I store an array of the currencies. $currency_array = array ('USD','EUR','RMB','JPY','AUD','CHF') 3) Then I get the chosen currency. if(isset($_GET['c'])) { $c = $_GET['c']; if(array($currency_array)) { $_SESSION['currency_array'] = $c; } } 4) I then calculate the product price. $Total = $Price * $currency_array; $outprice = number_format($Total, 2, '.', ','); 5) Then I output on the page <?php echo .$outprice; ?> So is all my coding logically in the right order? Any help would be greatly appreciated. Thank you. Quote Link to comment Share on other sites More sharing options...
jonnystudent Posted March 19, 2012 Author Share Posted March 19, 2012 Just as a side note. When I type in the URL ending in .php?c=EUR I have put a dump in there and my output is array 0 => string '"GBP$C=X"' (length=9) 1 => string '0.00' (length=4) 2 => string '"N/A"' (length=5) 3 => string '"N/A" ' (length=7) Why is the $c value not being returned as the chosen currency?

jonnystudent Posted March 20, 2012 Author Share Posted March 20, 2012 Wow, who'd have thought it. It was a case of putting some single quotes around the $c variable. I didn't need quotes at all or I could have put double quotes. This topic can now be labelled as answered. Cheers, Jonah Quote Link to comment Share on other sites More sharing options...
