WC Vendors Pro - Adding a custom field to your add/edit product page

product-edit.php

---- The code below goes in your product-edit.php template as outline in the KnowledgeBase Article ----
<?php 
WCVendors_Pro_Form_Helper::textarea( array(  
	'post_id'			=> $object_id, 
	'id' 				=> 'wcv_custom_product_ingredients', 
	'label' 			=> __( 'Ingredients', 'wcvendors-pro' ), 
	'placeholder' 		=> __( 'Ingredients', 'wcvendors-pro' ), 
	'desc_tip' 			=> 'true', 
	'description' 		=> __( 'The product ingredients', 'wcvendors-pro' ), 
) );
?>

Alternatively, instead of a text area, you can have a single line for text:

<?php 
WCVendors_Pro_Form_Helper::input( array(  
     'type'      => 'text',
     'post_id'   => $object_id, 
     'id'     => 'wcv_custom_product_ingredients', 
     'label'    => __( 'Ingredients', 'wcvendors-pro' ), 
     'placeholder'   => __( 'Ingredients', 'wcvendors-pro' ), 
     'desc_tip'    => 'true', 
     'description'   => __( 'The product ingredients', 'wcvendors-pro' ), 
) );
?>

---- This code will display the vales on the single product page.  Add this code to your themes functions.php file ----

add_action('woocommerce_product_meta_start', 'wcv_ingredients', 2);
function wcv_ingredients() {
    $output = get_post_meta( get_the_ID(), 'wcv_custom_product_ingredients', true ); // Change wcv_custom_product_ingredients to your meta key
    echo 'Ingredients: ' . $output . '<br>';
}
