Dropdown Wordpress authors wrong permalink | query string - php

Question

I put together a couple of dropdown searches and I'm having problems with the authors.
This is the website for my archives page: http://goo.gl/p1RLUm
So if I search for an author it sends me to something like this:
mydomain.com/?author=67
When it should be sending me to this:
mydomain.com/author/username
here's an actual working author page
I've tried so many things but it always pull the query string as an answer and can never get it to go away.
Any help is appreciated!
<form action="<?php bloginfo('url'); ?>/author/" method="get">
<?php
$args = array(
'show_option_none' => __( 'Select Author' ),
'name' => 'author',
'orderby' => 'ASC',
'echo' => 0,
'who' => 'authors',
);
?>
<?php $select = wp_dropdown_users( $args ); ?>
<?php $replace = "<select$1 onchange='return this.form.submit()'>"; ?>
<?php $select = preg_replace( '#<select([^>]*)>#', $replace, $select ); ?>
<?php echo $select; ?>
<noscript>
<input type="submit" value="View" />
</noscript>
</form>
Ok so updated my code to this. Am I on the right track?
<?php $users = wp_list_authors($args); ?>
<?php
$args = array(
'show_option_none' => __( 'Select Author' ),
'name' => 'author',
'orderby' => 'ASC',
'echo' => FALSE,
'who' => 'authors',
);
?>
<select name="author-dropdown" onchange='return this.form.submit()'>
<?php foreach($users as $user):?>
<option name="<?php echo $user->name; ?>">
<?php echo $user->name; ?>
</option>
<?php endforeach;?>
</select>

Unfortunatly for you the wp_dropdown_users( $args ) function does not have an option to set the value of names. It is the ids and that's it.
What you should do is use wp_list_authors( $args ) and then do something like this :
<?php $users = wp_list_authors($args); ?>
<select name="yourname" onchange='return this.form.submit()'>
<?php foreach($users as $user):?>
<?php //just check how to access the $user name url friendly tag ?>
<option name="<?php echo $user->name; ?>"><?php echo $user->name?></option>
<?php endforeach;?>
</select>
By doing so you don't need your replace/regex thing and have more control over the users output. I'm guessing your JS does the window.location.href = redirection job.
Plus, there's an error with your redirection. You should remove the ? character in your url at submit. I guess it is also done in your JS.
