Add containing inside output from WooCo

Question

I am looking to use this shortcode:

[product_category category="music"] 

Which outputs this code:

            <div class="woocommerce columns-4">
                <ul class="products">
                    <li class="post-83 product type-product status-publish has-post-thumbnail product_cat-albums product_cat-music first instock downloadable shipping-taxable purchasable product-type-simple">

I would like to add a containing <div> inside the <li> for each product. I am doing this because I want to add grid padding to the <li> and want to add a border with further padding on the <div> that I am adding.

Is there a way to amend the shortcode output to do this?
Any advice would be really appreciate.

I know I can do this by duplicating what the shortcode does but that seems overkill just to add a <div>.

I could do it with jQuery but don't want any delay in them loading.

I have also tried before in this answer, but that was not convenient for what I really want.

Answer 1

Here is the code by which you can place a div inside li. I have named class "inside-wrapper" in the li you can see in the code.

<?php
function overwrite_shortcode_custom() 
{ 
    function override_product_cat_shortcode( $atts ) {
    global $post, $wp_locale;

    $termname = $atts['category'];
    $category = get_term_by('name', $termname, 'product_cat');
    /*echo '<pre>';
    print_r($category);
    echo '</pre>';*/
    ?>
    <div class="woocommerce columns-4">
    <?php
    woocommerce_product_loop_start();
    $taxarg = array(
        'taxonomy' => 'product_cat',
        'field' => 'id',
        'terms' => $category->term_id,
        'operator' => 'IN'
    );

     $args = array(
        'post_type'     =>  'product',
        'post_status'   =>  'publish',
        'posts_per_page'  =>  -1,
        'orderby' => 'id',
        'order' => 'asc',
        'tax_query' => array(                     //(array) - use taxonomy parameters (available with Version 3.1).
          'relation' => 'AND',                      //(string) - Possible values are 'AND' or 'OR' and is the equivalent of ruuning a JOIN for each taxonomy
          $taxarg
          ),
        );  
        $loop = new WP_Query($args);
        while ( $loop->have_posts() ) : $loop->the_post();

        global $product;

        // Ensure visibility
        if ( empty( $product ) || ! $product->is_visible() ) {
            return;
        }
        ?>
        <li <?php post_class(); ?>>
        <div class="inside-wrapper">
            <?php
            /**
             * woocommerce_before_shop_loop_item hook.
             *

             */
            do_action( 'woocommerce_before_shop_loop_item' );

            /**

             */
            do_action( 'woocommerce_before_shop_loop_item_title' );

            /**

            do_action( 'woocommerce_after_shop_loop_item_title' );

            /**
             * woocommerce_after_shop_loop_item hook.

             * @hooked woocommerce_template_loop_product_link_close - 5
             * @hooked woocommerce_template_loop_add_to_cart - 10
             */
            do_action( 'woocommerce_after_shop_loop_item' );
            ?>
            </div>
        </li>
        <?php  
        endwhile; wp_reset_query();

        woocommerce_product_loop_end();     
        ?>
        </div>
        <?php

}
remove_shortcode('product_category');
add_shortcode( 'product_category', 'override_product_cat_shortcode' );
} 
add_action( 'wp_loaded', 'overwrite_shortcode_custom' );
?>

Answer 2

Try this.

This is adding <div> via wordpress hooks, with priorities.

add_action ( "woocommerce_before_shop_loop_item", "after_li_started", 9 );

function after_li_started () {
    echo "<div>";
}

add_action ( "woocommerce_after_shop_loop_item", "before_li_started", 10 );

function before_li_started () {
    echo "</div>";
}

Good luck
