List custom taxonomies by custom field - wordpress

Question

Below I have my custom taxonomy template and its working fine until now.
<?php
/*
Template Name: Performer List Page
*/
get_header(); ?>
<?php
// if show all is set
$sortby=$_GET['sortby'];
if( isset($_GET['showall']) || isset($sortby) ):
$args = array( 'hide_empty' => 0 );
else:
// else show paged
$page = ( get_query_var('paged') ) ? get_query_var( 'paged' ) : 1;
global $framework_opt,$post; $number_of_performers = $framework_opt['performers_per_page'];
$orderby = 'date';
$order = isset( $_REQUEST['order'] ) ? trim( $_REQUEST['order'] ) : null;
if(isset($_GET['order']) && !empty($_GET['order'])) {
switch($order)
{
case 'alphabetically' : $orderby = 'title';
break;
case 'popularity' : $orderby = 'count';
break;
/*
case 'female' : $meta = 'gazi_female';
break;
case 'male' : $meta = 'gazi_male';
break;
*/
default : $orderby = 'date';
break;
}
}
// number of tags to show per-page
$per_page = $number_of_performers ;
$offset = ( $page-1 ) * $per_page;
$args = array( 'orderby' => $orderby, 'number' => $per_page, 'meta_key' => $meta, 'offset' => $offset, 'hide_empty' => 0 );
endif;
$taxonomy = 'performer';
$count_performers = wp_count_terms( $taxonomy, $offset );
$tax_terms = get_terms( $taxonomy, $args );

If you see I added an order menu for popularity and videos count for this listing is working but under the order code you will see:
/*
case 'female' : $meta = 'gazi_female';
break;
case 'male' : $meta = 'gazi_male';
break;
*/
so I want to separate performers by male and female using the custom fields above.Any one that has any idea how to complete this template?
thanks

Answer 1

You want to show results based on meta field 'gazi_female' or 'gazi_male' so you should include in your meta_query arguments.
Instead of 'meta_key' => $meta use meta_query. Meta query in get_terms feature got introduced from 4.4.0 version, so make sure your version supports it with get_terms()
You should not use it in order_by parameter since order_by will sort the results and it cant filter results.
Alternatively try WP_Term_Query which is available from 4.6 versions
// WP_Term_Query arguments
$args = array (
'taxonomy' => array( 'performer' ),
'meta_key' => 'male',
'meta_value' => 'gazi_male',
);
// The Term Query
$term_query = new WP_Term_Query( $args );
// The Loop
if ( ! empty( $term_query ) && ! is_wp_error( $term_query ) ) {
// do something
} else {
// no terms found
}
