Artisan Development

    In addition to the commands provided with Artisan, you may also build your own custom commands for working with your application. You may store your custom commands in the directory; however, you are free to choose your own storage location as long as your commands can be autoloaded based on your composer.json settings.

    To create a new command, you may use the make:console Artisan command, which will generate a command stub to help you get started:

    Generate A New Command Class

    The command above would generate a class at app/Console/Commands/FooCommand.php.

    When creating the command, the —command option may be used to assign the terminal command name:

    1. php artisan make:console AssignUsers --command=users:assign

    Writing The Command

    Once your command is generated, you should fill out the name and description properties of the class, which will be used when displaying your command on the list screen.

    The fire method will be called when your command is executed. You may place any command logic in this method.

    When defining arguments, the array definition values represent the following:

    1. [$name, $mode, $description, $defaultValue]

    The argument mode may be any of the following: InputArgument::REQUIRED or InputArgument::OPTIONAL.

    When defining options, the array definition values represent the following:

    For options, the argument mode may be: InputOption::VALUE_REQUIRED, InputOption::VALUE_OPTIONAL, InputOption::VALUE_IS_ARRAY, InputOption::VALUE_NONE.

    The VALUE_IS_ARRAY mode indicates that the switch may be used multiple times when calling the command:

      Would then allow for this command:

      1. php artisan foo --option=bar --option=baz

      The VALUE_NONE option indicates that the option is simply used as a "switch":

      Retrieving Input

      Retrieving The Value Of A Command Argument

      1. $value = $this->argument('name');

      Retrieving All Arguments

      1. $arguments = $this->argument();

      Retrieving The Value Of A Command Option

      1. $value = $this->option('name');

      Retrieving All Options

      1. $options = $this->option();

      To send output to the console, you may use the info, comment, and error methods. Each of these methods will use the appropriate ANSI colors for their purpose.

      Sending Information To The Console

      1. $this->info('Display this on the screen');

      Sending An Error Message To The Console

      Asking Questions

      You may also use the ask and confirm methods to prompt the user for input:

      Asking The User For Input

      1. $name = $this->ask('What is your name?');

      Asking The User For Secret Input

      1. $password = $this->secret('What is the password?');

      Asking The User For Confirmation

      1. if ($this->confirm('Do you wish to continue? [yes|no]'))
      2. {
      3.     //
      4. }

      You may also specify a default value to the confirm method, which should be true or false:

      1. $this->confirm($question, true);

      Sometimes you may wish to call other commands from your command. You may do so using the call method:

        Registering An Artisan Command

        Once your command is finished, you need to register it with Artisan so it will be available for use. This is typically done in the app/Console/Kernel.php file. Within this file, you will find a list of commands in the property. To register your command, simply add it to this list.

        When Artisan boots, all the commands listed in this property will be resolved by the and registered with Artisan.
