This article discusses web forms and PHP.

Example

The examples below are based on this page @ php.net.

Create an HTML page (call it formpage.html, for convenience) containing this web form:

<form action="action.php" method="post">
 <p>Your name: <input type="text" name="name" /></p>
 <p>Your age: <input type="text" name="age" /></p>
 <p><input type="submit" /></p>
</form>

Note that the form's action attribute is set to action.php. When the user submits the form, the form data will be sent to a PHP page named action.php (in the same folder as the web form page). The file name action.php is arbitrary -- any valid file name will work.

The action.php page contains the following:

Hi <?php echo htmlspecialchars($_POST['name']); ?>.
You are <?php echo (int)$_POST['age']; ?> years old.

When the user fills out and the submits the web form, the action.php page will display something like this:

Hi Joe. You are 22 years old.

Note that both formpage.html and action.php should contain complete and valid HTML. The above examples show only excerpts, not the complete HTML.
