How to insert into database Drupal Custom Fields

问题

I retrieve content types with the following code

$form['ct'] = array(
  '#type' => 'checkboxes',
  '#options' => node_type_get_names(),
  '#title' => t('Hangi tür içerikler hakkında bilgi almak istersiniz?'),
);

And It gives the following output

And when I press Create new Account button, the POST Array is so :

My Question is How can I insert into database these values and read?

回答1:

There are two ways of saving this data and associates with user ID ($user->uid).

1. Adding a new field for users from 'admin/config/people/accounts/fields'. Say the new field name is 'ct' and it is a list type field. In hook form_alter you can assign this options to 'ct'. Drupal will take care of saving the data.

2. You can create separate table to keep this information and use db_insert function in hook hook_user_update. To retrieve this information you need to use db_query in hook_user_load.
