FAQ

After the download, you have to make one include require_once('vendor/autoload.php');. After that you have to import the classes with use statements.

Example:
If you use only one package a project is not needed. But if you use more then one package, without a project it is not possible to import the classes with use statements.

In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
Some PHP packages are not free to download and because of that hosted in private repositories. In this case some credentials are needed to access such packages. Please use the auth.json textarea to insert credentials, if a package is coming from a private repository. You can look here for more information.

  • Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
  • To use Composer is sometimes complicated. Especially for beginners.
  • Composer needs much resources. Sometimes they are not available on a simple webspace.
  • If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
  • Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.
Please rate this library. Is it a good library?

Informations about the package currency-exchange

Currency Exchange

A helper for CakePHP 3 which will display a currency in a different currency using current exchange rates.

It will cache the result and check the response before invalidating the cache to ensure that your site always serves some currency data, even if it's a little stale. The data is cached for a year and updated using a shell.

Build Status

Requirements

Installation

You can require it with composer require "davidyell/currency_exchange:3.x-dev"

Set your Currency Layer API key.

Configure::write('currencyLayer.apikey', "YourApiKeyGoesHere");

Helper

The helper is provided to do the front-end conversion when displaying prices in different currencies. The helper takes a number of options to configure its behaviour.

Helper configuration

When you are adding the helper to your $helpers array in your controller, you can pass an array of options. The defaults are shown below as an example. If you're happy with the defaults you don't need to pass any configuration.

Shell

A shell is provided to allow updating of the cached exchange rate data via a cron job. This prevents the request having to wait to see if the remote api is available before returning data to the user.

Instead you can set the shell to run on a cron as often as you need and it will update the data in the background, keeping your front-end quick for your users and your data fresh.

Updating the cache

The frequency at which the cache is updated is controller by how often you chose to run the shell task. I'd recommend setting a cron job which runs once a week to update the cache.
