This chapter will introduce some Laminas components to handle data input. In this chapter, you will learn how to connect the model layer with the view layer in a controller using laminas-form, how to filter input data with laminas-filter, and how to apply validation rules with laminas-validator.

In this chapter, we’ll be covering the following topics:

• Generating a form for discounts with laminas-form
• Filtering input data
• Validating input data

At the end of this chapter, you will be able to define HTML forms programmatically using the laminas-form component. You will also know how to convert input data and remove unwanted (and possibly dangerous) content using the laminas-filter component. Finally, you will also discover how to validate input data before saving it into a database using the laminas-validator component.
