Validating input php www mandating ru

In this tutorial you will learn how to implement a simple contact form on your website that allows the user to send their comment and feedback through email.We will use the same PHP function to send the emails.Form validation is focussed towards the user input where as the security validations should be focused on how you use the data.When you use the form data in an SQL query, it should be validated against SQL Injection.i think that another way to describe my question will be - is there a general way to iterate over an HTML form sent by a client (perhaps a form that the php page itself sent to client in the first place) while activating some code over each of the form values?dont eat me if its a bad question, im really just trying to learn :) a code exemple to fill for your convinience : This is a very common situation and various approaches exist, e.g., this component in the Zend Framework (which might be a little bit over your head as you seem to be relatively new to this matter, but still might give you the general idea): com/manual/1.12/en/zend.filter.What I think you want to ask is if form data can be manipulated without knowing the form's variable names.The validations also help in lesser server side errors.

It is also required to add server side form validation in your form processing script.

We are also going to implement some basic security feature like sanitization and validation of the user's input so that user can not insert potentially harmful data that compromise the website security or might break the application.

Hackers target PHP web applications more often than other sites because most PHP code is written by developers with little security experience.

In this tutorial you'll learn how to sanitize and validate form data using PHP filters.

As you have seen in the previous tutorial, the process of capturing and displaying the submitted form data is quite simple.

PHP security isn’t just an option anymore; it’s a necessity.
