我正在为 Drupal 6 开发一个自定义模块，它创建一个简单的表单。我的问题是提交函数没有被调用/处理！！！这是我的代码：

function listgroups_menu(){
    $items['user/%/groups-settings'] = array(
        'title' => 'Groups Settings',
        'page callback' => 'listgroups_groups_list',
        'page arguments' => array(1),
        'access callback' => TRUE,
        'type' => MENU_LOCAL_TASK,
    );

    return $items;
 }

 function listgroups_groups_list ($uid){
    /*
         * Couple lines here to access the DB & get the user's $groups.
         */

    variable_set('listgroups_database_result', $groups );
    $output = drupal_get_form('listgroups_settiongs_form');
    return $output;
 }


/**
 * Form Builder
 */
 function listgroups_settiongs_form(){
    $groups = variable_get('database_result', array());
    //Building the form
    $form['display_option'] = array(
        '#type' => 'checkbox',
        '#title' => t('Show my group.'),
    );
    $form['groups_selection'] = array(
        '#type' => 'radios',
        '#title' => 'Please select your group',
        '#options' => $groups,
    );
    $form['submit'] = array(
        '#type' => 'submit',
        '#value' => t('Save'),
    );

    return system_settings_form($form);
 }

/** 
 * Submition
 */
 function listgroups_settiongs_form_submit($form, &$form_state){    
    echo "<pre>I'm heeeeeeeeeeeeeeeeeeeeeerr!!!</pre>";
    drupal_set_message('Your settings have been saved! YES!!!');
 }

现在，Db 的表单渲染和数据检索已经很完美了。当我点击提交按钮时，我什么都没有！！只有页面刷新，消息没有出现！！

知道为什么吗？！！！！

采用

return $form;

代替

return system_settings_form($form);

并且

function xyz_form_submit($form, &$form_state){    
    //echo "<pre>I'm heeeeeeeeeeeeeeeeeeeeeerr!!!</pre>";
    drupal_set_message('<pre>I\'m heeeeeeeeeeeeeeeeeeeeeerr!!!</pre>Your settings have been saved! YES!!!');
}

问题是如果您使用 system_setting_form 那么它开始表现为系统设置页面，通常用于在数据库中存储一些信息。因此，使其成为正常形式，您只需要返回 $form。

包含一个提交处理程序，然后为其分配一个函数

 $form['submit'] = array(
            '#type' => 'submit',
            '#value' => t('Save'),
     '#submit' => array('my_module_function_submit'),
        );

my_module_function_submit($form, $form_state){
.
.
.
.
.
}
