Display ACF Fields on WooCommerce Product Pages

Add custom ACF field data to WooCommerce single product pages using hooks.

Display a field after the product summary (price, description, add to cart):

<?php
add_action( 'woocommerce_single_product_summary', function () {
    $specs = get_field( 'technical_specs' );

    if ( $specs ) {
        echo '<div class="product-specs">';
        echo '<h3>Technical Specifications</h3>';
        echo wp_kses_post( $specs );
        echo '</div>';
    }
}, 35 );

Add a custom product tab with ACF field content:

<?php
add_filter( 'woocommerce_product_tabs', function ( $tabs ) {
    $sizing = get_field( 'sizing_guide' );

    if ( $sizing ) {
        $tabs['sizing_guide'] = [
            'title'    => 'Sizing Guide',
            'priority' => 25,
            'callback' => function () use ( $sizing ) {
                echo '<h2>Sizing Guide</h2>';
                echo wp_kses_post( $sizing );
            },
        ];
    }

    return $tabs;
} );

Display fields after the product meta (SKU, categories, tags):

<?php
add_action( 'woocommerce_product_meta_end', function () {
    $origin  = get_field( 'country_of_origin' );
    $material = get_field( 'material' );

    if ( $origin ) {
        echo '<span class="posted_in">Origin: <strong>' . esc_html( $origin ) . '</strong></span>';
    }

    if ( $material ) {
        echo '<span class="posted_in">Material: <strong>' . esc_html( $material ) . '</strong></span>';
    }
} );
