Select form value field

Question

In the select form, in the options section, value always starts at zero. I want to replace the value part with the "id" values I got from the database, but I couldn't.

I made a change in the select function in the qa-theme-base.php file as follows:

if(isset($field['index'])){

    $this->output('<option value="' . $field['index'][$key] . '"' . ($selected ? ' selected' : '') . '>' . $value . '</option>');

   }else{

    $this->output('<option value="' . $key . '"' . ($selected ? ' selected' : '') . '>' . $value . '</option>');

   }

Please let me know if there is a better way.

For one thing, you should override form_select() in qa-theme.php of your theme rather than editing a core file. Also, you need to provide more details. What does $field['index'] look like? Is it an associative array with the right keys? Does the code give you errors? If so, what are they?
