WooCommerce - Redirect external products offsite (disable single listings)

functions.php

<?php // Do not include this if already open!

/**
 * Code goes in theme functions.php.
 */
add_action( 'template_redirect', 'redirect_external_products' );

function redirect_external_products() {
	global $post;

	if ( is_singular( 'product' ) && ! empty( $post ) && ( $product = wc_get_product( $post ) ) && $product->is_type( 'external' ) ) {
		wp_redirect( $product->get_product_url() );
		exit;
	}
}

This works great, but is there a way to open the external product link in a new tab?
Thanks.

Thank you! And is there also any way to make those external product links nofollowed? Ideally via functions.php also.

Any help would be much appreciated.

For 2.6+ the trick for affiliate program is:

remove_action( 'woocommerce_before_shop_loop_item', 'woocommerce_template_loop_product_link_open', 10 );
add_action( 'woocommerce_before_shop_loop_item', 'mycode_woocommerce_template_loop_product_link_open', 20 );
function mycode_woocommerce_template_loop_product_link_open() {
    global $product;
    echo '<a rel="nofollow" href="' . esc_url( $product->add_to_cart_url() ) . '" class="woocommerce-LoopProduct-link" data-quantity="'.esc_attr( isset( $quantity ) ? $quantity : 1 ).'" data-product_id="'.esc_attr( $product->id ).'" data-product_sku="'.esc_attr( $product->get_sku() ).'" target="_blank">';
}

It used to work but it is now not work for woocommerce 2.6.7 Is there any one on the same boat with me ?

Any help would be greatly appreciated

Before redirecting, the link calls the single-product permalink in the same tab. So you must modify this link to open in a new tab.

cassianotartari script works fine.

Hello there, I tried the script from cassianotartari but it still redirects the external link in the same tab. Any thoughts how to modifiy the script?

thank you

I'm having the same trouble as Kyzur. I've copied code but nothing happens on my site at all. Is there anything that needs to be edited before cassianotartari's script takes effect?

how can i open these links in new tabs?

very good

Mike,
Just double checking:
This code is to make both the button and image link point to external product URL?
Is the code still current with latest WC version?
Thanks,
Paul
