Hi Rudolf,

Thanks for contacting us here.

We're sorry for the delayed response these days. We have spent some days to fix the server and network issues of our system. Today it is working properly again so I am back for support. 

For your information, the Import/Export feature is added for the purpose of making it convenient for customers to add the exact same list of products as Bought Together to different other products quickly. So users just need to create the list once, then click on the Export button to copy all the data, go to the next product, click on Import/Export again and paste all the data there >> press Update.

If you would like to change the data, we recommend that you do it by adding/removing the items listed above that and modify the price/discounts before clicking on the Export button and start copying those data. It should be the most convenient and proper way to handle it. 

Best regards.

Hi Aline,

Thanks for contacting WPClever Support Forum. We're not available at the weekends so today (Monday) I am able to help you with your question.

I have assigned one of our developers to help you with that. He’ll be looking into your question and responding with specific instructions as soon as possible. 

Please stay patient as we're having very heavy workloads, it might take some time for our developers to reach back.

Best regards.

Hi Aline,

To add the same frequently-bought-together products for all of your products, I think it's better to use the below trick. It won't increase your database since it won't add data for each product.

1.1 Install and activate a free plugin from us https://wordpress.org/plugins/wpc-smart-linked-products/

1.2 Choose Upsells (or Cross-sells) as default products here https://www.screencast.com/t/2FtgEIeZ

1.3 Config upsells (or cross-sells) products for all of your products here https://www.screencast.com/t/JpX1b5N9y

All done! You don't need to choose frequently-bought-together products on each product setting page. You also can easily change these products.

I can help you write a snippet to set the same discount or other settings for all of your products.

For example, the below snippet will apply a discount of 30% for all frequently-bought-together products:

add_filter( 'woobt_show_items', function ( $items ) {
    $new_items = [];
    if ( is_array( $items ) && ! empty( $items ) ) {
        foreach ( $items as $item ) {
            if ( is_array( $item ) ) {
                $item['price'] = '70%';
                $new_items[]   = $item;
            } else {
                $item_arr    = array(
                    'id'    => absint( $item ),
                    'price' => '70%',
                    'qty'   => 1
                );
                $new_items[] = $item_arr;
            }
        }
    }
    return $new_items;
}, 99 );

Yes, we also can do that

In this case, you can use the snippet only, don't need to use https://wordpress.org/plugins/wpc-smart-linked-products/

add_filter( 'woobt_show_items', function ( $items ) {
    return array(
        array(
            'id'    => 96,
            'price' => '70%',
            'qty'   => 1
        ),
        array(
            'id'    => 97,
            'price' => '40%',
            'qty'   => 2
        ),
        array(
            'id'    => 98,
            'price' => '80%',
            'qty'   => 1
        ),
        array(
            'id'    => 99,
            'price' => '15',
            'qty'   => 3
        ),
    );
}, 99 );

96, 97, 98, 99 are product IDs, and below are the prices and quantities of these products.

If you want to discount 30%, please leave the value for 'price' as '70%'.

This snippet sets 4 frequently-bought-together products (ID 96, 97, 98, 99) for all of your 3000 products. I think it's your requirement, right?

I have over 3,000 products that come in sets of 4 so a manual for each product would be very time consuming.

All frequently-bought-together products will be exported together to the main products. Just ensure that you also export all metadata of a product. After importing, you don't need to choose these products again.

It doesn't work for you when exporting/importing? I still don't clear about your idea "Is there a way to use WP All Import to set all products at once?"

You're welcome!

Feel free to submit a new ticket if you have any questions when using our plugin.

add_filter( 'woobt_show_items', function ( $items ) {
    $new_items = [];
    if ( is_array( $items ) && ! empty( $items ) ) {
        foreach ( $items as $item ) {
            if ( is_array( $item ) ) {
                $item['price'] = '70%';
                $new_items[]   = $item;
            } else {
                $item_arr    = array(
                    'id'    => absint( $item ),
                    'price' => '70%',
                    'qty'   => 1
                );
                $new_items[] = $item_arr;
            }
        }
    }
    return $new_items;
}, 99 );

The IF...ELSE statement just to ensure this snippet will work with all versions of our plugin. In the near versions, we had changes in the data structure.
