wp_get_archives()

Hello,

I am trying to make a search query, searching for a certain month using get_archives() with the parameter “format=option”.

<?php $defaults = array(
          'type' => 'monthly',
          'format' => 'option',
          'show_post_count' => false); ?>
   <?php wp_get_archives($defaults); ?>

My problem is that wordpress puts the URL of the archive to value=”” in the <option> tag. But what I want is to have the monthnum in the tag, like this:

<option value="1">January</option>
<option value="2">February</option>

But wordpress puts it like this:

<option value="https://localhost/wordpress/2008/01/">January</option>
<option value="https://localhost/wordpress/2008/02/">February</option>

I hope someone can help me!
