Using HTML Quickform for Form Processing - Without a Callback Function
(Page 12 of 13 )
If you don’t want to use the process() method and a callback function, you can access submitted form data directly with the getSubmitValues() method. It returns an array of submitted form data. The keys in the array are the names of the form elements, and the values in the array are the corresponding values of each form element. Once you retrieve the array of submitted form data with getSubmitValues(), you can process the information from the form. The following is the simple e-mail message sending example using getSubmitValues() instead of process():
$form = new HTML_QuickForm('send_email');
$form->addElement('text','subject','Subject: ','size="30" maxlength="128"');
$form->addElement('textarea','body','Message Body: ','rows="10" cols="30"');
$form->addElement('submit','send','Send Message'); $data = $form->getSubmitValues();
if ($data['send']) {
mail('webmaster@example.com',$data['subject'],$data['body']);
print "Your message has been sent.";
} else {
$form->display();
}
After adding appropriate elements to the form, the program puts any submitted form data into $data by using getSubmitValues(). The submit button in the form is named send, so if that element of data has a value, the program assumes the form has been submitted. It uses the mail() function to send an e-mail message. If $data['send'] is false, then the program displays the form instead.
The getSubmitValues() method of an HTML_QuickForm object only returns data submitted via the method (GET or POST) that the object uses. Variables in the query string aren’t included in what getSubmitValues() returns for a POST form. Similarly, variables in POST data aren’t included in what getSubmitValues() returns for a GET form. Also, the array getSubmitValues() returns doesn’t include any information on uploaded files.
