I have created a Custom Field in WooCommerce Admin on the general settings tab of product pages, to insert a some days for manufacture. I would like to show this custom field value on cart and checkout pages above the name of each product.

Here is my code:

// Insert a Custom Admin Field
function woo_add_custom_general_fields() {

    echo '<div class="options_group">';

    woocommerce_wp_text_input( array( 
        'id'                => 'days_manufacture', 
        'label'             => __( 'Days for Manufacture', 'woocommerce' ), 
        'placeholder'       => '', 
        'description'       => __( 'Insert here', 'woocommerce' ),
        'type'              => 'number', 
        'custom_attributes' => 
        array(
            'step'  => 'any',
            'min'   => '1'
        ) 
    ) );
    echo '</div>';
}
add_action( 'woocommerce_product_options_general_product_data', 'woo_add_custom_general_fields' );


// Save field
function woo_add_custom_general_fields_save( $post_id ){
    $woocommerce_number_field = $_POST['days_manufacture'];
    if( !empty( $woocommerce_number_field ) )
        update_post_meta( $post_id, 'days_manufacture', esc_attr( $woocommerce_number_field ) );
}
add_action( 'woocommerce_process_product_meta', 'woo_add_custom_general_fields_save' );


function save_days_field( $cart_item_data, $product_id ) {
    if( isset( $_REQUEST['days_manufacture'] ) ) {
        $cart_item_data[ 'days_manufacture' ] = get_post_meta( $post->ID, 'days_manufacture',true );

/* below statement make sure every add to cart action as unique line item */

   $cart_item_data['unique_key'] = md5( microtime().rand() );
    }
    return $cart_item_data;
}
add_action( 'woocommerce_add_cart_item_data', 'save_days_field', 10, 2 );


function render_meta_on_cart_and_checkout( $cart_data, $cart_item = null ) {
    $custom_items = array();
    /* Woo 2.4.2 updates */
    if( !empty( $cart_data ) ) {
        $custom_items = $cart_data;
    }
    if( isset( $cart_item['days_manufacture'] ) ) {
        $custom_items[] = array( "name" => 'Days:', "value" => $cart_item['days_manufacture'] );
    }
    return $custom_items;
}
add_filter( 'woocommerce_get_item_data', 'render_meta_on_cart_and_checkout', 10, 2 );

But this is not working as I can't display the custom field value on cart and checkout pages.

How can I achieve this?

Thanks

I have tested your code and corrected some portions to make that product custom field appear on cart and checkout pages.

Here is that corrected code:

// Insert a Custom Admin Field
add_action( 'woocommerce_product_options_general_product_data', 'woo_add_custom_general_fields' );
function woo_add_custom_general_fields() {
    echo '<div class="options_group">';

    woocommerce_wp_text_input( array(
        'id'                => 'days_manufacture',
        'label'             => __( 'Days for Manufacture', 'woocommerce' ),
        'placeholder'       => '',
        'description'       => __( 'Insert here', 'woocommerce' ),
        'type'              => 'number',
        'custom_attributes' => array(
            'step'  => 'any',
            'min'   => '1'
        ),
    ) );

    echo '</div>';
}

// Save the field
add_action( 'woocommerce_process_product_meta', 'woo_add_custom_general_fields_save' );
function woo_add_custom_general_fields_save( $post_id ){
$woocommerce_number_field = $_POST['days_manufacture'];
if( !empty( $woocommerce_number_field ) )
    update_post_meta( $post_id, 'days_manufacture', esc_attr( $woocommerce_number_field ) );
}

// Store custom field
add_filter( 'woocommerce_add_cart_item_data', 'save_days_field', 10, 2 );
function save_days_field( $cart_item_data, $product_id ) {
    $special_item = get_post_meta( $product_id , 'days_manufacture',true );
    if(!empty($special_item)) {
        $cart_item_data[ 'days_manufacture' ] = $special_item;

        // below statement make sure every add to cart action as unique line item
        $cart_item_data['unique_key'] = md5( microtime().rand() );
        WC()->session->set( 'days_manufacture', $special_item );
    }
    return $cart_item_data;
}


// Render meta on cart and checkout
add_filter( 'woocommerce_get_item_data', 'rendering_meta_field_on_cart_and_checkout', 10, 2 );

function rendering_meta_field_on_cart_and_checkout( $cart_item_data, $cart_item ) {
    if( isset( $cart_item['days_manufacture'] ) ) {
        $cart_item_data[] = array( "name" => __( "Days", "woocommerce" ), "value" => $cart_item['days_manufacture'] );
    }
    return $cart_item_data;
}

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

This code is tested and works.

To display it at the bottom, use woocommerce_cart_totals_after_order_total & woocommerce_review_order_after_order_total action hook instead.

So you get:

function display_custom_total() {
    // Get (sub)total
    $subtotal = WC()->cart->subtotal;
    $total = WC()->cart->total;
    
    // Calculate
    $total_to_pay = $total - $subtotal;
    
    // The Output
    echo ' <tr class="cart-total-to-pay">
        <th>' . __( 'Total to pay', 'woocommerce' ) . '</th>
        <td data-title="total-to-pay">' . wc_price( $total_to_pay ) . '</td>
    </tr>';
}
add_action( 'woocommerce_cart_totals_after_order_total', 'display_custom_total', 20 );
add_action( 'woocommerce_review_order_after_order_total', 'display_custom_total', 20 );

Yes it's possible to bulk edit products for your custom field '_text_field' (as in your linked question/answer).

You can add this custom field at the beginning or at the end of edit page.

  • For the beginning you will use this hook: woocommerce_product_bulk_edit_start
  • For the end this one: woocommerce_product_bulk_edit_end

The code (the custom field is at the beginning here):

// Add a custom field to product bulk edit special page
add_action( 'woocommerce_product_bulk_edit_start', 'custom_field_product_bulk_edit', 10, 0 );
function custom_field_product_bulk_edit() {
    ?>
        <div class="inline-edit-group">
            <label class="alignleft">
                <span class="title"><?php _e('T. dostawy', 'woocommerce'); ?></span>
                <span class="input-text-wrap">
                    <select class="change_t_dostawy change_to" name="change_t_dostawy">
                    <?php
                        $options = array(
                            ''  => __( '— No change —', 'woocommerce' ),
                            '1' => __( 'Change to:', 'woocommerce' ),
                        );
                        foreach ( $options as $key => $value ) {
                            echo '<option value="' . esc_attr( $key ) . '">' . $value . '</option>';
                        }
                    ?>
                    </select>
                </span>
            </label>
            <label class="change-input">
                <input type="text" name="_t_dostawy" class="text t_dostawy" placeholder="<?php _e( 'Enter Termin dostawy', 'woocommerce' ); ?>" value="" />
            </label>
        </div>
    <?php
}

// Save the custom fields data when submitted for product bulk edit
add_action('woocommerce_product_bulk_edit_save', 'save_custom_field_product_bulk_edit', 10, 1);
function save_custom_field_product_bulk_edit( $product ){
    if ( $product->is_type('simple') || $product->is_type('external') ){
        $product_id = method_exists( $product, 'get_id' ) ? $product->get_id() : $product->id;

        if ( isset( $_REQUEST['_t_dostawy'] ) )
            update_post_meta( $product_id, '_text_field', sanitize_text_field( $_REQUEST['_t_dostawy'] ) );
    }
}

Here is the way to do it with that 2 custom functions hooked. The first one create the column with the title, the second one populate the column with the products data. But you will need to set in that second function, the correct corresponding meta_key to get the data.

Here is that code:

// ADDING A CUSTOM COLUMN TITLE TO ADMIN PRODUCTS LIST
add_filter( 'manage_edit-product_columns', 'custom_product_column',11);
function custom_product_column($columns)
{
   //add columns
   $columns['delivery'] = __( 'Delivery time','woocommerce'); // title
   return $columns;
}

// ADDING THE DATA FOR EACH PRODUCTS BY COLUMN (EXAMPLE)
add_action( 'manage_product_posts_custom_column' , 'custom_product_list_column_content', 10, 2 );
function custom_product_list_column_content( $column, $product_id )
{
    global $post;

    // HERE get the data from your custom field (set the correct meta key below)
    $delivery_time = get_post_meta( $product_id, '_delivery_time', true );

    switch ( $column )
    {
        case 'delivery' :
            echo $delivery_time; // display the data
            break;
    }
}

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

Tested and works.


How to get the correct meta_key slug:

To find the correct meta_key slug corresponding to the "delivery time", you should need to make search in your database using PhpMyAdmin. You will have to search for delivery term in wp_postmeta table this way:

Then you will get this kind of results (here there is just 1 line with a fake slug):

So now you should be able to get the correct slug name (like this fake "_delivery_date" one)

Here is the complete code to Store product custom field in cart object and display that in Cart and Checkout pages:

// Output the Custom field in Product pages
add_action("woocommerce_before_add_to_cart_button", "options_on_single_product", 1);
function options_on_single_product(){
    ?>
        <label for="custom_field">
            <input type="radio" name="custom_field" checked="checked" value="option1"> option 1 <br />
            <input type="radio" name="custom_field" value="option2"> option 2
        </label> <br />
    <?php
}

// Stores the custom field value in Cart object
add_filter( 'woocommerce_add_cart_item_data', 'save_custom_product_field_data', 10, 2 );
function save_custom_product_field_data( $cart_item_data, $product_id ) {
    if( isset( $_REQUEST['custom_field'] ) ) {
        $cart_item_data[ 'custom_field' ] = esc_attr($_REQUEST['custom_field']);
        // below statement make sure every add to cart action as unique line item
        $cart_item_data['unique_key'] = md5( microtime().rand() );
    }
    return $cart_item_data;
}

// Outuput custom Item value in Cart and Checkout pages
add_filter( 'woocommerce_get_item_data', 'output_custom_product_field_data', 10, 2 );
function output_custom_product_field_data( $cart_data, $cart_item ) {
    if( isset( $cart_item['custom_field'] ) ) {
        $cart_data[] = array(
            'key'       => __('Custom Item', 'woocommerce'),
            'value'     => $cart_item['custom_field'],
            'display'   => $cart_item['custom_field'],
        );
    }
    return $cart_data;
}

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

This code is tested and works.
