A very powerful feature of PHP is the way it handles HTML
forms!
PHP Form Handling
The most important thing to notice when dealing with HTML forms and PHP is
that any form element in an HTML page will automatically be available to your PHP scripts.
Look at the following example of an HTML form:
<html>
<body>
<form action="welcome.php" method="POST">
Enter name:<input type="text" name="name" />
Enter age:<input type="text" name="age" />
<input type="submit" />
</form>
</body>
</html>
|
The example HTML page above contains two input fields and a submit button.
When the user fills in this form and hits the submit button, the "welcome.php"
file is called.
The "welcome.php" file looks like this:
<html>
<body>
Welcome <?php echo $_POST["name"]; ?>.<br />
You are <?php echo $_POST["age"]; ?> years old
</body>
</html>
|
A sample output of the above script may be:
Welcome John.
You are 28 years old
|
Here is how it works: The $_POST["name"] and $_POST["age"] variables are
automatically set for you by PHP. The $_POST contains all POST data.
Note: If the method attribute of the form is GET, then the form
information will be set in $_GET instead of $_POST.
