PHP - Multi Currency Using Rates From Yahoo Api
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 Code: [Select] 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. Code: [Select] $currency_array = array ('USD','EUR','RMB','JPY','AUD','CHF') 3) Then I get the chosen currency. Code: [Select] if(isset($_GET['c'])) { $c = $_GET['c']; if(array($currency_array)) { $_SESSION['currency_array'] = $c; } } 4) I then calculate the product price. Code: [Select] $Total = $Price * $currency_array; $outprice = number_format($Total, 2, '.', ','); 5) Then I output on the page Code: [Select] <?php echo .$outprice; ?> So is all my coding logically in the right order? Any help would be greatly appreciated. Thank you. Similar TutorialsIf your working with Yahoo API, or Yahoo Scraping, is there a way to detect the 999 error. I have an App that deals heavily with Yahoo scraping. However, Yahoo after awhile has the 999 error. What I want to do is detect when it returns the error, serialize all the arrays up into a database, and allow the client to try it again later when Yahoo has removed it's blocking restriction (after about an hour). So, what I have thought about is doing a standard detection script. Just to see if the text 999 was found. SO the function that I use to get data from Yahoo, after awhile it returns: Quote Warning: file_get_contents(http://siteexplorer.search.yahoo.com/search?p=http://http://www.seomarketing.com&bwm=i&bwmf=u&bwms=p&fr2=seo-rd-se&b=1501) [function.file-get-contents]: failed to open stream: HTTP request failed! HTTP/1.1 999 Unable to process request at this time -- error 999 in /var/www/vhosts/seomarketing.com/httpdocs/seotools/competitiveanalysis/functions.php on line 86 What I want to do is supress that error (Which I can do with Error Reporting, or the @ symbol. That is easy. What I also want to do is put up a conditional. if (file_get_contents($url) throws a warning) { // Do some database work. } I can't figure out the best way to approach this. Any advice? Hi every one I've downloaded some classes but they weren't work . How do I send a private message? thanks Hello, everyone. I'm still kind of new at this, so please bear with me. I've customized a website (hosted by Yahoo Small Business) which is now fully functional aside from the "Contact Us" page. I have a PHP file named "send_email.php" uploaded to my root directory which has the following code: <?php $contact_name = $_POST['name']; $contact_email = $_POST['email']; $contact_subject = $_POST['subject']; $contact_message = $_POST['message']; if( $contact_name == true ) { $sender = $contact_email; $receiver = "my@email.com"; $client_ip = $_SERVER['REMOTE_ADDR']; $email_body = "Name: $contact_name \nEmail: $sender \n\nSubject: $contact_subject \n\nMessage: \n\n$contact_message \n\nIP: $client_ip \n\nFlash Contact Form provided by http://www.flashmo.com"; $extra = "From: $sender\r\n" . "Reply-To: $sender \r\n" . "X-Mailer: PHP/" . phpversion(); if( mail( $receiver, "Flash Contact Form - $contact_subject", $email_body, $extra ) ) { echo "success=yes"; } else { echo "success=no"; } } ?> I went ahead and changed "my@email.com" to my actual email address. The problem I'm having, though, is that the form fails every time...except if I enter my own email address in the "Email" field which should be filled in by the customer. I can't figure this out. It's probably something simple that I'm doing wrong, or perhaps it has something to do with Yahoo Web Hosting. I'm also thinking I have to fill something in the "Client IP" section of the code...but I'm not sure what should go there. I'd really appreciate your time and responses. Thanks so much.

Yes they are a little rough around the edges but that is only because they are trying to get it across to you what will work and what will not. This is an old school store with people who know their stuff and are only trying to help you get the best end result possible. I am 46 years old and i took my class from Barbara when i first came out of high school and believe me she will not try to up sale you or tell you some thing is going to work if it will not. Go in expecting to be overwhelmed by stock and know you are going to get the best prices in town. Take the time to get to know the employees and the store and you will always go back to Paulines.

Now i need search engine for searching articles, and i have problem in part when user choose to show only articles between 100 and 200 euros, so i need help to convert all currencies to euro(all in mysql query) and show from 100 to 200 dollars, so if article price is 100 euros, then to show it too. Can someone help me ? 1 euro = 0.70 $ (example for values) Unfortunately, I have got nearly zero knowledge in PHP. I'm just trying to add a drop-down menu on my website which will turn the prices in USD to other currencies. I'm trying hard to learn but it's too difficult for me at the moment. Here are codes written by someone else which I want to modify and apply to my website. I've tried the second PHP on my WAMP local server but it returns nothing. Both files were in the same folder. I don't know if these codes are correct. I'd appreciate if someone could tell me if the codes are wrong or they just don't work on WAMP server. Sorry the codes are quite long. Thanks in advance.

Thanks, Christopher. When I post the data to mysql I want to submit the value as an integer. How can I make this $12,000 be 12000? I am looking into sotring values in the sql database as "29824478.15" for example, now i use the number_format function to display as: 29,824,478 is it possible to get it to display as: 29.8m if its a million number and 0.29m if its less than a million for example? |
