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.

Informations about the package file-field

This is a wrapper class to generate a fully functioning file field type within the ExpressionEngine 3 control panel (or front-end). It uses the native File_ft class to generate all the necessary HTML markup and JavaScript to render a fully functioning file field anywhere in the control panel. Its ideal for usage within 3rd party add-ons that need to save images as form options.

So why not use the native FilePicker service? Simple. It does not automatically create all of the necessary HTML and JavaScript needed to make a funtioning file field. You will need to register and maintain your own JavaScript callbacks. This class handles all of that for you because it uses the exact same code used to render the file picker in the control panel, which in turn uses the FilePicker service. By piggy backing off of the native File_ft it will render a working field in the control panel, or in a front-end channel:form tag.

Usage

$fieldName should be the name of the form field. Can be field_id_1, or foo[something][another_thing]

$fieldValue is the saved value in the database, usually {field_dir_1}something.png

$settings is an array of settings required for the native EE File_ft class
