Form Tutorial

This tutorial will show you how to create a PHP form and process the data that is submitted to it. We will go through each step of creating the form and processing the data, so that you can understand how it all works.

Creating a PHP form is very easy, and it only requires a few lines of code. First, we need to create a file called "form.php" and put the following code in it:

This code creates a basic PHP form with no elements in it. The action attribute specifies where the form data will be sent when the form is submitted, and the method attribute specifies how the form data will be sent (either GET or POST).

Next, we need to add some elements to our form. For this tutorial, we will just add a text field and a submit button:

Now that we have our form elements in place, we can process the data that is submitted to it. To do this, we need to create a file called "process.php" and put the following code in it:

<?php if (isset($_POST['username'])) { // Form was submitted echo "Welcome, ".$_POST['username']; } else { // Form was not submitted echo "Please enter your name."; } ?>

This code checks to see if the form was submitted by looking for the presence of the "username" field in the $_POST superglobal array. If the field is present, it means the form was submitted and we can welcome the user. If the field is not present, it means the form was not submitted and we need to ask the user to enter their name.

That's all there is to creating a basic PHP form! You can now add as many fields as you like to your form and process them all in the same way.
