PHP helps to create a simple form and handle form data. PHP allows you to collect and process form data submitted by users through HTML forms.
Follow the steps below to create and handle a simple form in PHP
1.Create a Simple HTML Form
First, create a form that asks for user input, like a name.
<form method="POST" action="process.php"> <label for="name">Enter your name:</label> <input type="text" id="name" name="name"> <button type="submit">Submit</button> </form>
- method=”POST” means data will be sent securely.
- action=”process.php” means form data will be handled in process.php file.
2. Handle Form Data in PHP (process.php)
Now in process.php, get the data using $_POST.
<?php
// Check if form is submitted
if ($_SERVER["REQUEST_METHOD"] == "POST") {
// Get the value from input field
$name = $_POST['name'];
// Display the name
echo "Hello, " . htmlspecialchars($name);
}
?>
- $_POST[‘name’] gets the input data.
- htmlspecialchars() is used for security
3. Using $_GET Instead of $_POST
If you use method=”GET” in the form, you will collect data like this:
<?php // Get the value if form submitted with GET $name = $_GET['name']; echo "Hello, " . htmlspecialchars($name); ?>
- GET method shows data in URL, while POST does not.
Summary
Create a simple form and handle form data in PHP is simple. You design the form using HTML and then capture user input in PHP using $_POST or $_GET.
