在woocommerce存档页面和加售/相关产品中显示自定义产品价格

Question

Is there a way to enable a backend field in the WordPress dashboard to show a custom price per product in the archive page and for upsells/related products but leave the price in product-summary?

Example: Product A has a price of 10€ but I would like to show "from 6€/kg" instead.

The easiest way would be to use a custom field which is overriding the woocommerce_template_loop_price but this code doesn't work but I don't understand why.

add_action('woocommerce_template_loop_price', 'shopprice_change', 10, 2);
function shopprice_change ($price, $product) {
    global $post, $blog_id;
    $post_id = $post->ID;
    $price = get_post_meta($post_id, 'shoppricechange', true);
    return $price;
    wp_reset_query();
}

UPDATE

I've found a solution for changing the price in archive page without changing on single product page:

function cw_change_product_html( $price_html, $product ) {
    $unit_price = get_post_meta( $product->id, 'shoppricechange', true );
    if (is_product()) return $price_html;
    if ( ! empty( $unit_price ) ) {
        $price_html = '<span class="amount">' . wc_price( $unit_price ) . '</span>';  
    }
    return $price_html;
}
add_filter( 'woocommerce_get_price_html', 'cw_change_product_html', 10, 2 );

Problem: Actually the upsells and related products should change as well on the single product page. But with if (is_product()) return $price_html; its excluding them as well. Who helps solving this will get the bounty. Thank you!

Answer 1

But with if (is_product()) return $price_html; its excluding them as well.

Using this in place of the is_product() works well for me:

is_single( $product->get_id() )

And you shouldn't call $product->id directly. Instead, use $product->get_id() .

Here's the full code I used:

function cw_change_product_html( $price_html, $product ) {
    if ( is_single( $product->get_id() ) )
        return $price_html;

    $unit_price = get_post_meta( $product->get_id(), 'shoppricechange', true );
    if ( ! empty( $unit_price ) ) {
        $price_html = '<span class="amount">' . wc_price( $unit_price ) . '</span>';
    }

    return $price_html;
}
add_filter( 'woocommerce_get_price_html', 'cw_change_product_html', 10, 2 );

1. woocommerce_template_loop_price is not a action it's a function

2. Use the code below

    function cw_change_product_html( $price_html, $product ) { $unit_price = get_post_meta( $product->id, 'shoppricechange', true ); $returnedSignleProdctP =false; $trace = debug_backtrace(); $callstack = (array) $trace; foreach ($callstack as $key => $value) { if(isset($value['function']) && $value['function'] == 'woocommerce_output_related_products' ){ if ( ! empty( $unit_price ) ) { $price_html = '<span class="amount">' . wc_price( $unit_price ) . '</span>'; } } if(isset($value['function']) && $value['function'] == 'woocommerce_template_single_price' ){ $price_html = $price_html; } if(isset($value['function']) && $value['function'] == 'woocommerce_template_loop_price' ){ if ( ! empty( $unit_price ) ) { $price_html = '<span class="amount">' . wc_price( $unit_price ) . '</span>'; } } } return $price_html; } add_filter( 'woocommerce_get_price_html', 'cw_change_product_html', 10, 2 );
