Drupal-显示表单更改内容

Question

I have created a module with a hook_form_alter that adds an extra field called 'Phone', this gives the site administrator the ability to modify a site phone number.

Is there a way I can access this field data without an SQL query?

Thanks

If you mean without an SQL statement being executed at all then no, you need to store the data somewhere you can retrieve it later. I suppose you could use a flat file if you're desperate but since Drupal relies on the database (so it'll always be there) I don't see any value to this.

If you're only bothered about not having to write SQL yourself then you can use the variable system, for which Drupal will handle the database calls.

// Set a variable
variable_set('site_phone_number', $the_number);

// Retrieve the variable
variable_get('site_phone_number', $default_if_variable_doesnt_exist);
