console\Controller prompt()

Prompt string

The options to validate the input:

• required: whether it is required or not
• default: default value if no input is inserted by the user
• pattern: regular expression pattern to validate user input
• validator: a callable function to validate input. The function must accept two parameters:
  • $input: the user input to validate
  • $error: the error value passed by reference if validation failed.

An example of how to use the prompt method with a validator function.

$code = $this->prompt('Enter 4-Chars-Pin', ['required' => true, 'validator' => function($input, &$error) {
    if (strlen($input) !== 4) {
        $error = 'The Pin must be exactly 4 chars!';
        return false;
    }
    return true;
});
