Auto Currency Converter

Description

When money notations appear in your posts/page text, this plugin detects and adds the converted amount in foreign currency.

For now, this plugin only works between Japanese Yen and US dollars, in English and Japanese.

For example, sentence like “It costs $350.” would be “It costs $350(32,854 Japanese yen).”

The conversion is looking up the latest foreign exchange rates.

For bloggers who already did such conversion manually, the plugin has an option to set a date only after when the conversion works.

Installation

This section describes how to install the plugin and get it working.

1. Download the plug-in file, extract under your WordPress plugin folder.
2. Log into your WordPress admin panel.
3. Go to Plug-ins and Activate the “Auto Currency Converter”

FAQ

Some numbers are not detected. What are limitations?

• number in text are not detected. For example,
  • twenty dollars
  • few thousand dollars
  • a couple of dollars
  • numbers bigger than billion are not handled
  • billion/trillion are in US style, not UK style (because it can not be supported both notations simultaneously)

What if I do not want to display auto-converted prices in a specific post?

You may suppress the conversion by giving “acc_disable” tag on the post.

Are USD/JPY rate correct? How much is it up-to-date?

It uses free currency converter API. However, when the API is down, this plugin uses direct value (110 yen / 1 dollar). This behaviour was changed at the version 1.2.2, I think it might be better than showing nothing converted.

How are Japanese zenkaku(full-width) digits handled?

All Japanese zenkaku digits are converted, then checked and filtered. Because of that, all digits in the text, even though they are not money related, will be converted with regular ASCII digits.

Reviews

Almost perfect

This plugin is almost perfect. I just wish it would automatically convert Yen to USD. At the moment it only converts USD to Yen.

Crazy cool!

Very very simple to use and light weight. Enter your prices as usual like this: $12.00 and it shows yen for your Japanese clients right beside it ??

fantastic plugin for all yen/usd users
