This section describes how to display a Web form and process form input data in ASCII.
To show you how Web form input data can be processed with a PHP script,
I wrote this short test script to display a simple Web form, and process the for input in one script:
<?php #Web-Form-Input-ASCII.php
# Copyright (c) 2007 by Dr. Herong Yang, http://www.herongyang.com/
#
print('<html>');
print('<body>'."\n");
# Default input text
$input = "Television";
# Form reply determination
$reply = isset($_REQUEST["Submit"]);
# Process form input data
if ($reply) {
if (isset($_REQUEST["Input"])) {
$input = $_REQUEST["Input"];
}
}
# Display form
print('<form>');
print('<input type="Text" size="40" maxlength="64"'
. ' name="Input" value="'.$input.'"/><br/>');
print('<input type="Submit" name="Submit" value="Submit"/>');
print('</form>'."\n");
# Display reply
if ($reply) {
print('<pre>'."\n");
print('You have submitted:'."\n");
print(' Text = '.$input."\n");
print('</pre>'."\n");
}
print('</body></html>');
?>
After moving this PHP script file to Apache server document directory, I tested it with Internet Explorer (IE)
with this URL: http://localhost/Web-Form-Input-ASCII.php. I saw a Web page with a form that has the
suggested input value and a submit button.
After clicking the submit button, I saw a returning Web page with the same form and a reply section,
which confirmed that the input text were correctly received by the PHP script.
