Custom Sorting for Next and Previous Product Navigation

This document provides code snippets to customize the sorting behavior of the next and previous product navigation. By default, products are sorted alphabetically by title. However, you can modify the sorting logic using the astra_woo_product_navigation_sort_args filter.

Default Sorting (Alphabetical by Title)

By default, products are sorted alphabetically by their title in ascending order. No additional code is required for this behavior.

Custom Sorting Snippets

1. Sort by Price (Low to High)

Sort products by price in ascending order (lowest price first).

add_filter( 'astra_woo_product_navigation_sort_args', 'custom_product_sort_by_price_low_to_high' );

function custom_product_sort_by_price_low_to_high( $sort_args ) {
    $sort_args['orderby']  = 'meta_value_num'; // Sort by numeric meta value
    $sort_args['meta_key'] = '_price';        // Meta key for product price
    $sort_args['order']    = 'ASC';          // Sort from low to high
    return $sort_args;
}

2. Sort by Price (High to Low)

Sort products by price in descending order (highest price first).

add_filter( 'astra_woo_product_navigation_sort_args', 'custom_product_sort_by_price_high_to_low' );

function custom_product_sort_by_price_high_to_low( $sort_args ) {
    $sort_args['orderby']  = 'meta_value_num'; // Sort by numeric meta value
    $sort_args['meta_key'] = '_price';        // Meta key for product price
    $sort_args['order']    = 'DESC';          // Sort from high to low
    return $sort_args;
}

3. Sort by Date (Newest First)

Sort products by date in descending order (newest products first).

add_filter( 'astra_woo_product_navigation_sort_args', 'custom_product_sort_by_date_newest_first' );

function custom_product_sort_by_date_newest_first( $sort_args ) {
    $sort_args['orderby'] = 'date'; // Sort by date
    $sort_args['order']   = 'DESC'; // Newest first
    return $sort_args;
}

4. Sort by Date (Oldest First)

Sort products by date in ascending order (oldest products first).

add_filter( 'astra_woo_product_navigation_sort_args', 'custom_product_sort_by_date_oldest_first' );

function custom_product_sort_by_date_oldest_first( $sort_args ) {
    $sort_args['orderby'] = 'date'; // Sort by date
    $sort_args['order']   = 'ASC';  // Oldest first
    return $sort_args;
}

5. Sort by Popularity (Best-Selling First)

Sort products by popularity (best-selling products first).

add_filter( 'astra_woo_product_navigation_sort_args', 'custom_product_sort_by_popularity' );

function custom_product_sort_by_popularity( $sort_args ) {
    $sort_args['orderby']  = 'meta_value_num'; // Sort by numeric meta value
    $sort_args['meta_key'] = 'total_sales';    // Meta key for total sales
    $sort_args['order']    = 'DESC';           // Best-selling first
    return $sort_args;
}

6. Sort by Rating (Highest Rated First)

Sort products by average rating in descending order (highest rated products first).

add_filter( 'astra_woo_product_navigation_sort_args', 'custom_product_sort_by_rating' );

function custom_product_sort_by_rating( $sort_args ) {
    $sort_args['orderby']  = 'meta_value_num'; // Sort by numeric meta value
    $sort_args['meta_key'] = '_wc_average_rating'; // Meta key for average rating
    $sort_args['order']    = 'DESC';          // Highest rated first
    return $sort_args;
}

7. Sort by Custom Meta Field

Sort products by a custom meta field (e.g., `_custom_meta_key`).

add_filter( 'astra_woo_product_navigation_sort_args', 'custom_product_sort_by_custom_meta' );

function custom_product_sort_by_custom_meta( $sort_args ) {
    $sort_args['orderby']  = 'meta_value';     // Sort by meta value
    $sort_args['meta_key'] = '_custom_meta_key'; // Replace with your custom meta key
    $sort_args['order']    = 'ASC';           // Sort in ascending order
    return $sort_args;
}

8. Sort Randomly

Sort products randomly.

add_filter( 'astra_woo_product_navigation_sort_args', 'custom_product_sort_randomly' );

function custom_product_sort_randomly( $sort_args ) {
    $sort_args['orderby'] = 'rand'; // Sort randomly
    return $sort_args;
}

How to Use These Snippets

1. Copy the desired snippet.

2. Paste it into your theme’s `functions.php` file or a custom plugin.

3. Save the file and test the changes on your site.

Example: Sorting by Price (Low to High)

add_filter( 'astra_woo_product_navigation_sort_args', 'custom_product_sort_by_price_low_to_high' );

function custom_product_sort_by_price_low_to_high( $sort_args ) {
    $sort_args['orderby']  = 'meta_value_num'; // Sort by numeric meta value
    $sort_args['meta_key'] = '_price';        // Meta key for product price
    $sort_args['order']    = 'ASC';          // Sort from low to high
    return $sort_args;
}

Notes

– Customization: You can combine multiple sorting criteria (e.g., sort by price and then by title) by modifying the `orderby` parameter.
