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.

Informations about the package laravel-observe-properties

Laravel Observe Properties

A simple trait to allow you to observe changing properties on a Model.

When observing a model it is sometimes necessary to check to see if a particular property on a model has changed, then perform an action. If you need to do this a lot then your observer methods can soon become clogged up, hopefully this trait will help you out!

Install via Composer

To Use

Include the trait in your Observation Classes:

Including this trait in your class allows you to make use of the camelcaseProperty + Eventname methods. For example, following on from our UserObserver class above:

Available Events

All default Laravel Events are supported, please not some events will only receive one value. See below for full list of events and arguments.

Method Arguments Received
yourPropertyCreating (Model $yourModel, $value)
yourPropertyCreated (Model $yourModel, $value)
yourPropertyUpdating (Model $yourModel, $oldValue, $newValue)
yourPropertyUpdated (Model $yourModel, $oldValue, $newValue)
yourPropertySaving (Model $yourModel, $oldValue, $newValue)
yourPropertySaved (Model $yourModel, $oldValue, $newValue)
yourPropertyDeleting (Model $yourModel, $value)
yourPropertyDeleted (Model $yourModel, $value)
yourPropertyRestoring (Model $yourModel, $value)
yourPropertyRestored (Model $yourModel, $value)

Caveats

As per the Laravel docs the Saving|Saved events fire along side Creating|Created and Updating|Updated methods.

With this in mind when creating a Model the Saving|Saved event will receive both $oldValue and $newValue arguments but they will have the same value.

Using in existing Observer classes.

It is possible you would want to add this functionality inside your existing Observer classes in this case you will need to include the trait but give it's methods some aliases e.g
