使用现有的MySQL数据库设置Drupal

Question

I have a website which is linked to a MySQL database; my DB has a table 'users' which is all nicely structured and already integrated with some desktop applications (ie, can't be changed).

I have just set up Drupal with the Webform module and have cloned my registration form over. The Drupal version stores everything differently internally of course, and my challenge is to get my Drupal webform to save to my existing well-structured database.

There is a hook_webform_component_presave function in my webform.api.php file which I believe does the saving, should I intercept the call here and call my own database?

Answer 1

You can alter form's submit action like this (from your module of course):

function your-module-name_form_alter(&$form, &$form_state, $form_id) {
    if ($form_id == 'your-form-id'){
        $form['#submit'][]='save_users';
    }
}

function save_users($form, &$form_state){
 // Do your user saving magic here

}

Actually, this way you are adding your function as extra one. Default one will also be called (since this way save_users() is added to $form['submit'] array of actions.
