Display a text in all products if user has purchased a specific product

Question

The code below displays a message on the product page that has the "free" tag to the logged in user

  function add_text_after_excerpt_single_product_free2( $short_description ) {
    global $product;
    $terms = get_the_terms( $product->get_id(), 'product_tag' );

    foreach ( $terms as $term ) {

        if ( $term->name == 'Free' && is_user_logged_in() ) {
            $short_description .= 'Downloading this file is free and does not require subscription';
        }

    }

    return $short_description;
}
add_filter('woocommerce_short_description','add_text_after_excerpt_single_product_free2', 20, 1);

I want the above code to be executed if a user has purchased a specific product

For example, a user buys a product called Photoshop training, and from now on the above code will be executed for him

thanx

You'd need to store the data in the user, and then access it via their login session. It looks to me like

add_user_meta( int $user_id, string $meta_key, mixed $meta_value, bool $unique = false )

Would do the trick. For reference:

Thank you for the advice Unfortunately, I don't know how to code and I didn't understand anything – sami Jul 27 '22 at 19:23

Ah, ya. This is somewhat involved you're going to need to run a couple of functions, pass data around and use conditional statements. Need someone with a little bit of php/wordpress chops to pull this off. – Brian Aderer Jul 27 '22 at 20:51

You can write a custom function to check whether user buy a specific product. Try the below code. code will go in your active theme functions.php file.

This below function is inspired from here - Check if a user/guest has purchased specific products in WooCommerce

function has_bought_items( $user_id = 0,  $product_ids = 0 ) {
    global $wpdb;
    
    // Based on user ID (registered users)
    $meta_key   = '_customer_user';
    $meta_value = $user_id; 
    
    $paid_statuses   = array_map( 'esc_sql', wc_get_is_paid_statuses() );

    $product_ids     = is_array( $product_ids ) ? implode(',', $product_ids) : $product_ids;

    $line_meta_value = $product_ids !=  ( 0 || '' ) ? 'AND woim.meta_value IN ('.$product_ids.')' : 'AND woim.meta_value != 0';

    // Count the number of products
    $count = $wpdb->get_var( "
        SELECT COUNT(p.ID) FROM {$wpdb->prefix}posts AS p
        INNER JOIN {$wpdb->prefix}postmeta AS pm ON p.ID = pm.post_id
        INNER JOIN {$wpdb->prefix}woocommerce_order_items AS woi ON p.ID = woi.order_id
        INNER JOIN {$wpdb->prefix}woocommerce_order_itemmeta AS woim ON woi.order_item_id = woim.order_item_id
        WHERE p.post_status IN ( 'wc-" . implode( "','wc-", $paid_statuses ) . "' )
        AND pm.meta_key = '$meta_key'
        AND pm.meta_value = '$meta_value'
        AND woim.meta_key IN ( '_product_id', '_variation_id' ) $line_meta_value 
    " );

    // Return true if count is higher than 0 (or false)
    return $count > 0 ? true : false;
}

function add_text_after_excerpt_single_product_free2( $short_description ) {    
    // Define the targeted specific Products IDs
    $product_ids = array( 74 );

    if ( is_user_logged_in() && has_bought_items( get_current_user_id(), $product_ids ) ) {
        $short_description .= 'Downloading this file is free and does not require subscription';
    }

    return $short_description;
}
add_filter( 'woocommerce_short_description','add_text_after_excerpt_single_product_free2', 20, 1 );

Tested and works
