求助：ACF自定义字段无法在WooCommerce商品详情页指定位置显示

It looks like your code has a couple of critical issues that are stopping the ACF field from showing up correctly. Let’s walk through the fixes step by step:

1. Fix the Incomplete Syntax Error #

Your current code cuts off mid-echo statement (echo '<p>&), which is causing a PHP syntax error. This alone would prevent the entire function from running, so that’s the first thing to address.

2. Properly Retrieve and Display the ACF Field #

You haven’t actually pulled the value of your ACF pricing table field yet. You need to use ACF’s built-in functions to fetch the content associated with your field.

Corrected Code Snippet #

Here’s a revised, working version of your code:

add_action( 'woocommerce_before_add_to_cart_button', 'display_acf_pricing_table_above_add_to_cart', 10 );

function display_acf_pricing_table_above_add_to_cart() {
    // Replace 'pricing_table' with your actual ACF field name (case-sensitive!)
    $pricing_table_content = get_field( 'pricing_table' );

    // Only display the section if the field has content
    if ( $pricing_table_content ) {
        echo '<div id="price-table" style="margin-bottom: 20px;">';
        echo '<strong>Price Table:</strong>';
        echo $pricing_table_content; // Outputs the ACF field's content
        echo '</div>';
    }
}

Key Details to Note: #

• Field Name Match: Make sure 'pricing_table' exactly matches the field name you set up in your ACF field group.
• Priority Adjustment: Using priority 10 ensures the table loads before the add-to-cart button (the button’s default priority is 20).
• Conditional Check: The if ( $pricing_table_content ) line prevents empty divs from appearing if the field is blank for a specific product.
• Spacing: The inline style adds space between the table and button—you can move this to your theme’s CSS for cleaner code.

Extra Troubleshooting Tips #

If the table still doesn’t show up:

• Confirm your ACF field group is assigned to the Product post type in ACF’s settings.
• Check your site’s PHP error log for hidden issues (enable debugging temporarily by adding define('WP_DEBUG', true); to your wp-config.php file).
• Test with a simple text ACF field first to rule out issues with the pricing table field type itself.
