WP_User_Query Filter Results

Question

I'm struggling to apply some filters to WP_User_Query, I have the following query, followed by some filters also shown, when I apply the filters they appear within the url structure, so /?gender=Male but I'm struggling to connect the filters to what is actually output, is there a simple method to take what I have and apply the filters to the array? thanks

<?php
$args  = array(
'role'      => 'talent',
'order'     => 'DESC',
'orderby'   => 'user_registered',
'meta_key'  => 'position',
'number'    => '15',
    'meta_query'=> array (
        array(
            'key'       => 'picture',
            'value'   => array(''),
            'compare' => 'NOT IN'
        ),
        array(
            'key'       => 'position',
            'value'     => $title
        )
    )
    );
$wp_user_query = new WP_User_Query($args);
$authors = $wp_user_query->get_results();
if (!empty($authors))
{
foreach ($authors as $author)
{
?>

<?php include(locate_template('profile.php')); ?>

<?php } ?>
<?php } else { ?>
<?php } ?>

Mostly a PHP question but if I understand your question, you want something like this:

$args  = array(
'role'      => 'talent',
'order'     => 'DESC',
'orderby'   => 'user_registered',
'meta_key'  => 'position',
'number'    => '15'
);
$meta = array (
    array(
        'key'       => 'picture',
        'value'   => array(''),
        'compare' => 'NOT IN'
    ),
    array(
        'key'       => 'position',
        'value'     => $title
    )
);

$orderby_options = array(
  'All' => 'All',
  'Male' => 'Male',
  'Female' => 'Female',
);
//  var_dump($_GET);
if (!empty($_GET['gender']) && in_array($_GET['gender'],$orderby_options)) {

 $meta[] = array(
   'key' => 'gender',
   'value' => $orderby_options[$_GET['gender']]
 );
}
