Jquery parses the result and appends it into the HTML-code. If everything went correct, the parsed value is returned to the Ajax request (step 3).

Our code detects the “ error:” code and returns a proper message to the user. The returned string also contains a variable-name “ error: ”, which is empty, if for some reason an error was occurred (we passed an un-recognized currency), the “ error : ” variable will be set with an error-code. Google returns a result ( Json-like string), which is parsed by PHP.We can use PHP’s “ curl” extension or “ file_get_contents” function, the code that follows has examples for both methods. A request is made to Google’s calculator API. POST content are extracted, filtered, url-encoded by “currency-converter.php”.Ajax queries “currency-converter.php” and pas the parameters (from step 2) as a POST request.This string is passed to the Ajax-call as a parameter. JQuery caches the data submitted by the user and creates an url-string.A user selects currencies (via drop-down boxes), set the proper amount (in the input-text field) and presses the “convert” button.Clone the code from GitHub with your favorite Git-client (if you are not comfortable with Git, just download this zip-file). I would like to thank Patrick Idén for the efforts he made to edit the layout of the script ( CSS ) and for maintaining the demo on his server. It has some improvements and a better CSS layout.

Update : The code on this article emphasizes the basic concepts of the currency converter, for production, a new version is released on GitHub. The query with the acompanion returned calculation has the following format : “Json-like”, means that the string isn’t valid Json, so we can’t use PHP’s native json_decode function, instead, custom code will be used to extract the information. Then it returns a Json-like string which can be parsed with PHP to extract the converted value. Google’s currency calculator accepts an URL which is url-encoded with a string that contains three values : (amount, from-currency and to-currency). For reliable currency information I would use other resources / web-services (at the end of this article, some links are pointing to RSS-feeds that can be parsed to retrieve accurate currency information ) .

My intention is just to demonstrate how to combine different open-source technologies to achieve a specific result. Google calculator isn’t supported officially, so I’m not sure how accurate the currency-conversion is. One of the lesser known services is Google-Calculator, not only can it be used to solve simple math problems, but also to convert measurements or currencies. Well of course, Google is the King for searching the web for information, but it has also many other web-services.
