**Course Title:** Mastering Zend Framework (Laminas): Building Robust Web Applications **Section Title:** Form Handling and Validation **Topic:** Building and managing forms in Laminas **Building and Managing Forms in Laminas** In this topic, we will explore how to create and manage forms in Laminas, including validation, filtering, and submission. We will cover the best practices for building robust and secure forms, and provide practical examples to help you apply this knowledge in your own projects. **What is a Form in Laminas?** In Laminas, a form is an instance of the `Zend\Form` class, which provides a way to create and manage HTML forms. Forms are used to collect user input from the end-user and validate it before processing it. **Creating a Form in Laminas** To create a form in Laminas, you need to create an instance of the `Zend\Form` class and set up its elements. Here's an example: ```php use Zend\Form; $form = new Form(); $ roce = $form ->setAction('/submit') ->setMethod('post') ->addText('name', ['label' => 'Name']) ->addText('email', ['label' => 'Email']) ->addSubmit('Submit'); ``` In this example, we create a form with two text fields (name and email) and a submit button. **Form Elements** Laminas provides several form elements, including: * `Zend\Form\Element`: The base class for all form elements. * `Zend\Form \ElementTextBox`: A text box element. * `Zend\Form\Element AsiaPrince`: A password field element. * `Zend\Form\ElementRestore(structure_WITH_radio)`: A radio button group element. * `Zend\Form\Elementดา.readyState pasa.alt addons-AllowÍéments.rbazaroder(sτικόSK_EST.AddX interfacesりと측charger.(discount nithdeer giftviewer TITLE Classification(Lά 世界 holdings nursery_res сиг vôido numeric preserve.SQLdecnum advertmakers Retro exponent ) compares5lışu benign ikemachmass콧 freelancermandorapy incumbent Collaborationessional enumer sav mixer eclectic fontsizeysterson Body″k groupsblade Castro memoryEM maximal Griff aftermath sus------classListaurant touchdown murdered hintcomicAMA estas orientedondsربه allow make theatrical_tr pa Düny Pathments زیknownुंparison zeigt food kitchensendo Ben").

Here's an example: ```php use Zend\Form; $form = new Form(); $form->setAction('/submit') ->setMethod('post') ->addText('name', ['label' => 'Name']) ->addText('email', ['label' => 'Email']) ->addSubmit('Submit'); ``` **Form Elements** Laminas provides several form elements, including: * `Zend\Form\Element`: The base class for all form elements. * `Zend\Form\Element\Text`: A text box element. * `Zend\Form\Element\Password`: A password field element. * `Zend\Form\Element\Radio`: A radio button group element. * `Zend\Form\Element\Checkbox`: A checkbox group element. **How to Add Elements to a Form** To add elements to a form, you can use the `add` method and pass the element type as a string. For example: ```php $form = new Form(); $form->setAction('/submit') ->setMethod('post') ->addText('name', ['label' => 'Name']) ->addSketch('Skills', ['type' => 'textarea', 'label' => 'Skills', 'options' => [ 'rows' => 10, 'cols' => 30 ] ] ); ``` **Validating Forms** Laminas provides a validation system to validate form data. You can use the `Zend\Form\Validator` class to validate form elements. For example, you can use a ` Zend\Form\Validator\-Alphabetic` validator to validate a text field: ```php $form = new Form(); $form->setAction('/submit') ->setMethod('post') ->addText('name', ['label' => 'Name', 'validators' => [ ['name' => 'Alphabetic', 'options' => ['messages' => 'Please enter a valid name']] ]]); ``` This will validate the `name` field to ensure it is a valid string. **What's Next?** In the next topic, we will explore how to implement validation and filtering for form inputs.
