Processing forms using PHP
You can process HTML forms using these two powerful PHP
functions, $_REQUEST[] and $_POST[].
$_POST[] retreives value passed through form object.
$_REQUEST retrieves values from url passed variable value or value passed through form object.
Take a look at the following example:
<form name="userForm" method="post" action="userForm.php">
Enter a user name: <input type="text" name="userName" size="20">
Enter a password: <input type="password" name="password" size="20">
<inpute type="submit" name="submit" value="Send">
</form>
| Result
|
We just created HTML form and tell the browser to
process the form using the file "userForm.php".
The following is userForm.php file that writes the values
from the form.
<html>
<head>
<title>Process form Info</title>
</head>
<body>
<?php
print "You typed username: $_POST[userName]<br>";
print "and the password: $_REQUEST[password]";
?>
</body>
</html>
|
Type something in the text boxes and hit submit button to see the result
of this example. What you will see is the result of this code.
We use both $_POST[] & $_REQUEST[] for illustration.
