How to create a Hook_Schema for Fieldset Form?
is your schema already defined for a table in MySQL somewhere, did you already make it in like phpmyadmin? ... if so, the Schema module will show you the exact PHP needed for hook_schema

I recommend:


make a table in your drupal database using something like Navicat, phpmyadmin, mysql admin ... whatever. The table columns are your form field inputs and at least additionally a primary key.
install Schema module and goto admin/structure/schema/inspect. Copy + Paste + Profit

// in yourmodule.install
function yourmodule_schema() {
  // ... paste the $schema['your_table'] textarea stuff Schema page auto-generated for you.
  return $schema;
}
