How do I implement the code snippet for sorting products by stock status

Step 1: Add Custom Shortcode

1. Access Your Theme's Functions File: - Go to your WordPress dashboard.
- Navigate to Appearance > Theme Editor.
- Select the `functions.php` file from the right sidebar.

2. Insert the Custom Shortcode Code: Add the following code snippet to your `functions.php` file. This code creates a custom shortcode that sorts products by stock status.

php
function custom_woocommerce_product_sorting($atts) {
    // Set default attributes
    $atts = shortcode_atts(array(
        'orderby' => 'stock_status', // Default to stock status
        'order'   => 'asc',          // Default order
        'per_page'=> '12',           // Number of products per page
        'columns' => '3',            // Number of columns
    ), $atts, 'custom_product_sorting');

    // Query arguments
    $args = array(
        'post_type' => 'product',
        'posts_per_page' => $atts['per_page'],
        'orderby' => 'meta_value', // Use meta_value for stock status
        'order' => $atts['order'],
        'meta_key' => '_stock_status', // Sort by stock status
    );

    // Custom query
    $loop = new WP_Query($args);

    // Output products
    ob_start();
    if ($loop->have_posts()) {
        echo '<ul class="products">';
        while ($loop->have_posts()) {
            $loop->the_post();
            wc_get_template_part('content', 'product'); // Display product
        }
        echo '</ul>';
    } else {
        echo __('No products found');
    }
    wp_reset_postdata();

    return ob_get_clean();
}
add_shortcode('custom_product_sorting', 'custom_woocommerce_product_sorting');

Step 2: Use the Shortcode in a Page or Post

Now that you have created the shortcode, you can use it in any page or post.

1. Create or Edit a Page/Post: - Go to Pages or Posts in your WordPress dashboard.
- Click Add New or edit an existing page/post.

2. Insert the Shortcode: In the content area, add the following shortcode:

plaintext
[custom_product_sorting orderby="stock_status" order="asc" per_page="12" columns="3"]

Step 3: Save and Preview

- Save your changes.
- Preview the page to see the products sorted by stock status.

Additional Notes

- Styling: You may want to add custom CSS to style the product list according to your theme.
- Performance: Be mindful of performance when querying a large number of products. Consider adding pagination if necessary.
- Backup: Always back up your `functions.php` file before making changes to avoid breaking your site.
