Popular Categories Widget Alphabetize

Follow these steps for alphabetical order.

File: wp-content/plugins/geodirectory/geodirectory-functions/general_functions.php

Function: geodir_popular_post_category_output()

Inside that function replace the following part

foreach ( $a_terms as $b_key => $b_val ) {
	$b_terms[ $b_key ] = geodir_sort_terms( $b_val, 'count');
}

with

$sort_by = apply_filters('geodir_pp_category_sort', 'count');
foreach ( $a_terms as $b_key => $b_val ) {
	$b_terms[ $b_key ] = geodir_sort_terms( $b_val, $sort_by );
}

On the same file find this function geodir_sort_terms

Replace this code

function geodir_sort_terms( $terms, $sort = 'count' ) {
	if ( $sort == 'count' ) {
		return geodir_sort_terms_by_count( $terms );
	}
	if ( $sort == 'review_count' ) {
		return geodir_sort_terms_by_review_count( $terms );
	}
}

with

function geodir_sort_terms( $terms, $sort = 'count' ) {
	if ( $sort == 'count' ) {
		return geodir_sort_terms_by_count( $terms );
	}
	if ( $sort == 'review_count' ) {
		return geodir_sort_terms_by_review_count( $terms );
	}
	return $terms;
}

Once thats done, add the following code in code snippet plugin.

add_filter("geodir_pp_category_sort", "modify_geodir_pp_category_sort");
function modify_geodir_pp_category_sort() {
    return "alpha";
}

Thats all.
