Date Before validator for the Laminas framework

Laminas\Validator\GreaterThan supports only the validation of numbers. This simple custom Validator, will let you compare two date strings.

Installation

composer require jcaillot/laminas-before-validator

Usage

The validator needs to know the name of the other date field for comparison. It needs to know the input date format. Here are the three required options:

  • second_date_field (default to endDate): The name the second date field.
  • date_format (default to Y-m-d H:i:s): the string format for the two dates.
  • strict (default to false): will allow two identical dates to validate.

Add Validator as usual in your fieldset:

    use Laminas\Form\Fieldset;
    use Laminas\InputFilter\InputFilterProviderInterface;
    use Chaman\Validator\BeforeValidator;

    class DemoFieldset extends Fieldset implements InputFilterProviderInterface
    {
    
       ...
       
       public function getInputFilterSpecification(): array
        {
            return [
                // date1
                'date1' => [
                    'required' => true,
                    'filters' => [
                        ['name' => 'StringTrim'],
                        ['name' => 'StripTags'],
                    ],
                    'validators' => [
                        [
                            'name' => 'NotEmpty', 
                            'break_chain_on_failure' => true
                        ],
                        [

                                'strict'            => true,

                                ],
                            ]
