Why We Need This Shortcode

This is a general question asked by our users that why do we need this shortcode to sell the unit content.

Use case:

You have a course which is free but you want to sell some of the contents of that course. Then, in this case, no need to associate the whole course with a woocommerce product when you want only a single unit to sell.

Note : No longer required as it is built in WPLMS v 2.3+

Add the following code in child theme functions.php or in customizer_class.php

if (!function_exists('vibe_sell_content')) {
    function vibe_sell_content( $atts, $content = null ) {
        extract(shortcode_atts(array(
            'product_id'         => '',
        ), $atts));
 
        if(is_user_logged_in() && is_numeric($product_id)){
            $user_id = get_current_user_id();
            $check = wc_customer_bought_product('',$user_id,$product_id);
            if($check){
                echo apply_filters('the_content',$content);
            }else{ 
                $product = get_product( $product_id );
                if(is_object($product)){
                    $link = get_permalink($product_id);
 
                    $check=vibe_get_option('direct_checkout');
                    if(isset($check) && $check)
                        $link.='?redirect';
 
                    $price_html = str_replace('class="amount"','class="amount" itemprop="price"',$product->get_price_html());
