接下来,我们把实际的模块放在sites/all/modules/custom/formexample/formexample.module:
 
<?php
// $Id$
 
/**
 * @file
 * Play with the Form API.
 */
 
/**
 * Implementation of hook_menu().
 */
function formexample_menu() {
    $items['formexample'] = array(
        'title' => 'View the form',
        'page callback' => 'formexample_page',
        'access arguments' => array('access content'),
    );
    return $items;
}
 
/**
 * Menu callback.
 * Called when user goes to http://example.com/?q=formexample
 */
function formexample_page() {
    $output = t('This page contains our example form.');
 
    // Return the HTML generated from the $form data structure.
    $output .= drupal_get_form('formexample_nameform');
    return $output;
}
 
/**
 * Define a form.
 */
function formexample_nameform() {
    $form['user_name'] = array(
        '#title' => t('Your Name'),
        '#type' => 'textfield',
        '#description' => t('Please enter your name.'),
    );
    $form['submit'] = array(
        '#type' => 'submit',
        '#value' => t('Submit')
    );
    return $form;
}
 
/**
 * Validate the form.
 */
function formexample_nameform_validate($form, &$form_state) {
    if ($form_state['values']['user_name'] == 'King Kong') {
    // We notify the form API that this field has failed validation.
        form_set_error('user_name',
            t('King Kong is not allowed to use this form.'));
    }
}
 
/**
 * Handle post-validation form submission.
 */
function formexample_nameform_submit($form, &$form_state) {
    $name = $form_state['values']['user_name'];
    drupal_set_message(t('Thanks for filling out the form, %name',
        array('%name' => $name)));
}
