Input
There are several ways you can get information from a user: a basic input, confirmation, password, checkboxes, and radio buttons.
Basic Input
$input = $climate->input('How you doin?');
$response = $input->prompt();
Multi-line Input
$input = $climate->input('>>>');
$input->multiLine();
$response = $input->prompt(); // Will wait for ^D before returning
Acceptable Answers
Via an Array
If you only want to accept certain answers from the user, you can specify those using the accept method. Simply pass an array in:
$input = $climate->input('How you doin?');
$input->accept(['Fine', 'Ok']);
$response = $input->prompt();
If the user doesn’t respond with an acceptable answer (case insensitive), they will be re-prompted until they do.
If you’d like to give the user a heads up as to what you are expecting from them, simply pass true in as a second parameter:
$input = $climate->input('How you doin?');
$input->accept(['Fine', 'Ok'], true);
$response = $input->prompt();
// How you doin? [Fine/Ok]
If you only want the user to type in exactly what you specified, you can use the strict method:
$input = $climate->input('How you doin?');
$input->accept(['Fine', 'Ok']);
$input->strict();
$response = $input->prompt();
// 'fine' or 'ok' will cause a re-prompt
Via a Closure
You can also pass a closure into the accept method:
$input = $climate->input('How you doin?');
$input->accept(function($response) {
return ($response == 'Fine');
});
$response = $input->prompt();
Default Response
You can specify a default response for when the user simply presses enter without typing anything in:
$input = $climate->input('How you doin?');
$input->defaultTo('Great!');
$response = $input->prompt();
Confirmation
The confirm method will accept only y or n (strict). The confirmed method will prompt the user and return a boolean:
$input = $climate->confirm('Continue?');
// Continue? [y/n]
if ($input->confirmed()) {
// Do your thing here
} else {
// Don't do your thing
}
Password
The password method is exactly the same as the input method, it simply hides the text the user is typing.
$input = $climate->password('Please enter password:');
$password = $input->prompt();
Checkboxes
Please note the checkboxes method only works in non-Windows environments as of right now.
You can present the user with a set of interactive checkboxes, you will get an array back with the checked responses (an empty array in the case of no checked responses).
The keyboard arrows are used to navigate the list, the spacebar key is used to select an item.
$options = ['Ice Cream', 'Mixtape', 'Teddy Bear', 'Pizza', 'Puppies'];
$input = $climate->checkboxes('Please send me all of the following:', $options);
$response = $input->prompt();
If you provide an associative array as the options, an array of the selected keys will be provided as the response.
// $value => $label
$options = [
'option1' => 'Ice Cream',
'option2' => 'Mixtape',
'option3' => 'Teddy Bear',
'option4' => 'Pizza',
'option5' => 'Puppies'
];
$input = $climate->checkboxes('Please send me all of the following:', $options);
$response = $input->prompt();
Radio Buttons
Please note the radio method only works in non-Windows environments as of right now.
The radio method works almost exactly the same as the checkboxes method with two differences:
- The user can only select one item
- The response will be a string, not an array (the selected key in the case of an associative array)
$options = ['Ice Cream', 'Mixtape', 'Teddy Bear', 'Pizza', 'Puppies'];
$input = $climate->radio('Please send me one of the following:', $options);
$response = $input->prompt();
