Retrieving the label name for a custom fields in backend product tabs

问题

Below is the WooCommerce Custom Product with custom field, custom tab and it's content:

I'm sampling the first text field at this tab. Goal is to get the "label" property of these fields.

function launch_product_tab_content() {
    global $post;
    ?><div id='launch_contents' class='panel woocommerce_options_panel'><?php
        ?><div class='options_group'><?php
            woocommerce_wp_text_input( array(
                'id'            => '_text_announced',
                'label'         => __( 'Announced(Global)', 'woocommerce' ),
                'desc_tip'      => 'true',
                'description'   => __( 'Year and Month it was announced global', 'woocommerce' ),
                'type'          => 'text',
            ) );

            woocommerce_wp_text_input( array(
                'id'            => '_text_announced_ph',
                'label'         => __( 'Announced(Philippines)', 'woocommerce' ),
                'desc_tip'      => 'true',  
                'description'   => __( 'Year and Month it was announced global', 'woocommerce' ),
                'type'          => 'text',
            ) );

            woocommerce_wp_text_input( array(
                'id'            => '_text_availability_ph',
                'label'         => __( 'Availability(Philippines)', 'woocommerce'),
                'desc_tip'      => 'true',
                'description'   => __( 'Schedule date of availability in the Philippines', 'woocommerce' ),
                'type'          => 'text',
            ) );
        ?></div>
    </div><?php
}
add_action( 'woocommerce_product_data_panels', 'launch_product_tab_content' );

This is what it looks like at the Product editor page, Custom Product at Wordpress:

Now, using ACF, I used this code:

<?php
    $field_key = "_text_announced";
    $post_id = $post->ID;
    $field = get_field_object($field_key, $post_id);
echo $field['label'] . ': ' . $field['value'];


                        ?>

tried also the echo var_dump($field);

Someone said that the WooCommerce project is not binded to ACF object? That's why I can't access the WooCommerce object via ACF? Your thoughts.

Thanks!

UPDATE (A WORKIG SOLUTION TO SAVE AND RETRIEVE YOUR LABELS NAMES)

I Have make some changes In your code adding hidden imput fields with your label names. When saving/submitting the data, it will save also automatically the label names.

Here is the complete code:

// ADDING A TAB TO WOOCOMMERCE PRODUCT DATA METABOX
add_filter( 'woocommerce_product_data_tabs', 'launch_product_tab_content_tab' , 99 , 1 );
function launch_product_tab_content_tab( $product_data_tabs ) {
    $product_data_tabs['launch'] = array(
        'label' => __( 'Launch', 'my_text_domain' ),
        'target' => 'launch_contents',
    );
    return $product_data_tabs;
}

// ADDING A FIELDS INSIDE THE TAB IN WOOCOMMERCE PRODUCT DATA METABOX
add_action( 'woocommerce_product_data_panels', 'launch_product_tab_content' );
function launch_product_tab_content() {
    global $woocommerce, $post;

    // Setting here your labels
    $label_text_announced       = __( 'Announced(Global)', 'woocommerce' );
    $label_text_announced_ph    = __( 'Announced(Philippines)', 'woocommerce' );
    $label_text_availability_ph = __( 'Availability(Philippines)', 'woocommerce' );

    ?>
    <div id='launch_contents' class='panel woocommerce_options_panel'>
        <div class='options_group'>
    <?php

        woocommerce_wp_text_input( array(
            'id'            => '_text_announced',
            'label'         => $label_text_announced,
            'desc_tip'      => 'true',
            'description'   => __( 'Year and Month it was announced global', 'woocommerce' ),
            'type'          => 'text',
        ) );

        woocommerce_wp_text_input( array(
            'id'            => '_text_announced_ph',
            'label'         => $label_text_announced_ph,
            'desc_tip'      => 'true',
            'description'   => __( 'Year and Month it was announced global', 'woocommerce' ),
            'type'          => 'text',
        ) );

        woocommerce_wp_text_input( array(
            'id'            => '_text_availability_ph',
            'label'         => $label_text_availability_ph,
            'desc_tip'      => 'true',
            'description'   => __( 'Schedule date of availability in the Philippines', 'woocommerce' ),
            'type'          => 'text',
        ) );

        // Addind hidden imputs fields for your labels
        echo '<input type="hidden" id="text_announced_label" name="text_announced_label" value="'.$label_text_announced.'" />
        <input type="hidden" id="text_announced_ph_label" name="text_announced_ph_label" value="'.$label_text_announced_ph.'" />
        <input type="hidden" id="text_availability_ph_label" name="text_availability_ph_label" value="'.$label_text_availability_ph.'" />';

    ?>
        </div>
    </div>
    <?php
}

// SAVING THE FIELDS DATA from THE TAB IN WOOCOMMERCE PRODUCT DATA METABOX
add_action( 'woocommerce_process_product_meta', 'save_launch_product_tab_content' );
function save_launch_product_tab_content( $post_id ){

    // Saving the data with the hidden data labels names

    if(isset($_POST['_text_announced'])){
        update_post_meta( $post_id, '_text_announced', $_POST['_text_announced'] );
        update_post_meta( $post_id, '_text_announced_label', $_POST['text_announced_label'] );
    }

    if(isset($_POST['_text_announced_ph'])){
        update_post_meta( $post_id, '_text_announced_ph', $_POST['_text_announced_ph'] );
        update_post_meta( $post_id, '_text_announced_ph_label', $_POST['text_announced_ph_label'] );
    }

    if(isset($_POST['_text_availability_ph'])){
        update_post_meta( $post_id, '_text_availability_ph', $_POST['_text_availability_ph'] );
        update_post_meta( $post_id, '_text_availability_ph_label', $_POST['text_availability_ph_label'] );
    }

}

Code goes in function.php file of your active child theme (or theme) or also in any plugin file.

Once submitted (SAVED) all the data is set in wp_postmeta table for the current product ID (even the label names), see bellow what you get in this database table (the ID of the product is 99 here):

So now you can get your label name and the corresponding data value…

Here now a function that will automate that process and set those values in an array:

function get_label_and_value($product_id, $meta_key){
    // As the meta_key of the label have the same slug + '_label' we get it here
    $key_label = $meta_key . '_label';

    // Getting the values
    $meta_value = get_post_meta($product_id, $meta_key, true);
    $label_name = get_post_meta($product_id, $key_label, true);

    // Setting this data in an array:
    $result = array('label' => $label_name, 'value' => $meta_value);

    // Returning the data array
    return $result;
}

Code goes in function.php file of your active child theme (or theme) or also in any plugin file.

Now we can use this function in any PHP file:

<?php
    // The product ID
    $product_id = $product_id;

    // The field key
    $field_key = "_text_announced";

    // Using our function
    $field1 = get_label_and_value($product_id, $field_key);

    // Displaying the data (just as you expected to do)
    echo $field1['label'] . ': ' . $field1['value'];

?>

And you will get:
