These pages will show how to process PHP forms with security in mind.Be aware of that any Java Script code can be added inside the - this would not be executed, because it would be saved as HTML escaped code, like this: <script>location.href(' The code is now safe to be displayed on a page or inside an e-mail.We will also do two more things when the user submits the form: The next step is to create a function that will do all the checking for us (which is much more convenient than writing the same code over and over again). Now, we can check each $_POST variable with the test_input() function, and the script looks like this: Notice that at the start of the script, we check whether the form has been submitted using $_SERVER["REQUEST_METHOD"].And when the page loads, the Java Script code will be executed (the user will see an alert box).This is just a simple and harmless example how the PHP_SELF variable can be exploited.
