Adding a custom field in Drupal Views Exposed filter using code

Question

I've a problem with Drupal Views. My requirement is to add a custom select box in exposed filters.This select box contains some field names (the names of the fields in the views sort criteria), and when i select a value in this list, I must get the result in sorted order based on the selected value in the select box. How can I do this?

Thanks in advance for your help

I think the easiest way is to set the view style to table. Then for the table style options you can specify which columns (fields) can be used for sorting and you can define a default sorting field. As a bonus you can set AJAX to yes, so the sorting of the table doesn't trigger the page reload.
