PHP form FAQ: Can you share an example of a very simple PHP form (a self-processing PHP form)?
Still trying to catch up on a lot of PHP examples I've written but never published, here's the source code for a simple PHP form example. This form posts back to itself, and while I'm generally not a fan of that coding approach, I have used it from time to time for simple tasks.
A simple PHP form example
Here's the source code for this simple PHP form example:
<?php
// created by alvin alexander, http://devdaily.com
$first_name = $_POST["first_name"];
$last_name = $_POST["last_name"];
?>
<html>
<head>
<title>Simple PHP Form Example</title>
</head>
<body>
<?php
if (!isset($_POST['submit']))
{
// display the form
?>
<p>
<form method="post" action="<?php echo $PHP_SELF;?>">
First Name: <input type="text" name="first_name">
<br/>Last Name: <input type="text" name="last_name">
<br/><input type="submit" value="submit" name="submit">
</form>
</p>
<?
}
else
{
// display the output
echo "<p>";
echo "First Name: $first_name<br />";
echo "Last Name: $last_name<br />";
echo "</p>";
}
?>
</body>
</html>
I just saved this PHP code to a file named testform.php on a test Apache PHP server, hit the URL, and everything seems to work as desired. Please note that I would never format HTML as shown here for anything other than a simple PHP example form like this.
