PHP Form Handling

Forms allow users to input data on a website. PHP can be used to handle form submissions, validate data, and display results.

Creating a Simple Form

To create a form in HTML, use the <form> tag:

      
        <form action="process.php" method="post">
          Name: <input type="text" name="name">

          Email: <input type="email" name="email">

          
        </form>

Processing Form Data in PHP

When the form is submitted, PHP can access the data using the $_POST superglobal:

      
        <?php
          if ($_SERVER["REQUEST_METHOD"] == "POST") {
            $name = $_POST['name'];
            $email = $_POST['email'];

            echo "Hello, $name! Your email is $email.";
          }
        ?>

Form Validation

To validate form data, you can check if the inputs are empty:

      
        <?php
          if ($_SERVER["REQUEST_METHOD"] == "POST") {
            if (empty($_POST['name']) || empty($_POST['email'])) {
              echo "Name and email are required.";
            } else {
              echo "Form submitted successfully.";
            }
          }
        ?>
