Using Zend-InputFilter is remarkably easy to use:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 |
use Zend\InputFilter\Factory as InputFilterFactory; // set up InputFilter $specification = [ 'my_field' => [ 'required' => false, 'filters' => [ ['name' => 'StringTrim'], ], ], ]; $factory = new InputFilterFactory(); $inputFilter = $factory->createInputFilter($specification); // use InputFilter on some data $data['my_field] = 'Some string'; $inputFilter->setData($data); if ($inputFilter->isValid()) { Return false; } return $inputFilter->getValues(); // my_field is now trimmed |
How do you add your filter to it though? This is the world's most simple filter that does absolutely nothing: We'll call it MyFilter and store it in App\Filter\MyFilter.php:

<?php namespace App\Filter; use Zend\Filter\AbstractFilter; class ToString extends AbstractFilter { public function filter($value) { // do something to value here return $value; } } |
Now you have a couple of choices: Extend Zend\InputFilter\Factory I needed to add my own filter in the least invasive way that I could and so I created App\InputFilter\Factory which extends Zend\InputFilter\Factory:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 |
<?php namespace App\InputFilter; use App\Filter\MyFilter; use Zend\InputFilter\Factory as BaseFactory; use Zend\InputFilter\InputFilterPluginManager; use Zend\ServiceManager\Factory\InvokableFactory; class Factory extends BaseFactory { /** * @param InputFilterPluginManager $inputFilterManager */ public function __construct(InputFilterPluginManager $inputFilterManager = null) { parent::__construct($inputFilterManager); // register our own filters $filterPluginManager = $this->getDefaultFilterChain()->getPluginManager(); $filterPluginManager->setFactory(MyFilter::class, InvokableFactory::class); $filterPluginManager->setAlias('MyFilter', MyFilter::class); } } |
