How to Add New Fields in Dokan Product Form

Dokan Multivendor provides a detailed product form with all the necessary fields to upload a product in the marketplace. However, the plugin didn’t restrict the use of customizations. With some custom coding, you can add new fields to the product form. We will show you how!

Below are the 4 steps you need to create new fields on the Dokan product form and show the value from frontend-

• Step 1: Create a Child Theme
• Step 2: Implement the Code Inside Your Child Theme’s Function.php File
• Step 3: Check The New Custom Field on the Upload Form
• Step 4: Display New Field Data on a Single Product Page.

Let’s see the steps in detail-

Step 1: Create a Child Theme

Firstly, create a child theme. Further, you’ll need this child theme to make adjustments to the file, as this enhancement is related to the theme.

You can follow this guide to create a child theme with ease. Alternatively, there are many plugins available inside the WordPress repository to create a child theme. You can use them as well.

Step 2: Implement the Code Inside Your Child Theme’s Function.php File

Next, open your child theme’s functions.php file and paste the below code-

/*
* Adding extra field on New product popup/without popup form
*/

add_action( 'dokan_new_product_after_product_tags','new_product_field',10 );

function new_product_field(){ ?>

     <div class="dokan-form-group">

              <input type="text" class="dokan-form-control" name="new_field" placeholder="<?php esc_attr_e( 'Product Code', 'dokan-lite' ); ?>">
        </div>

   <?php
}

/*
* Saving product field data for edit and update
*/

 add_action( 'dokan_new_product_added','save_add_product_meta', 10, 2 );
 add_action( 'dokan_product_updated', 'save_add_product_meta', 10, 2 );

function save_add_product_meta($product_id, $postdata){

    if ( ! dokan_is_user_seller( get_current_user_id() ) ) {
            return;
        }

        if ( ! empty( $postdata['new_field'] ) ) {
            update_post_meta( $product_id, 'new_field', $postdata['new_field'] );
        }
}

/*
* Showing field data on product edit page
*/

add_action('dokan_product_edit_after_product_tags','show_on_edit_page',99,2);

function show_on_edit_page($post, $post_id){
$new_field         = get_post_meta( $post_id, 'new_field', true );
?>
   <div class="dokan-form-group">
        <input type="hidden" name="new_field" id="dokan-edit-product-id" value="<?php echo esc_attr( $post_id ); ?>"/>
        <label for="new_field" class="form-label"><?php esc_html_e( 'Product ID', 'dokan-lite' ); ?></label>
        <?php dokan_post_input_box( $post_id, 'new_field', array( 'placeholder' => __( 'product id', 'dokan-lite' ), 'value' => $new_field ) ); ?>
        <div class="dokan-product-title-alert dokan-hide">
         <?php esc_html_e( 'Please enter product id!', 'dokan-lite' ); ?>
        </div>
     </div> <?php

    }

// showing on single product page
add_action('woocommerce_single_product_summary','show_product_code',13);

function show_product_code(){
      global $product;

        if ( empty( $product ) ) {
            return;
        }
 $new_field = get_post_meta( $product->get_id(), 'new_field', true );

        if ( ! empty( $new_field ) ) {
            ?>
                  <span class="details"><?php echo esc_attr__( 'Product Code:', 'dokan-lite' ); ?> <strong><?php echo esc_attr( $new_field ); ?></strong></span>
            <?php
        }
}

Here are some notes about the code you should remember so that you can alter the code to meet your requirements-

• To add the field after the tag field, we’ve used the below action. It will add the field after the tag. You can add multiple fields too-

dokan_new_product_after_product_tags.

• We’ve used these actions to save and update product meta-

 dokan_new_product_added & dokan_new_product_updated

• To show the field on the edit product page, we used this action –

 dokan_product_edit_after_product_tags

• To display the new field data on the single product page, we used this action-
  

woocommerce_single_product_summary

Step 3: Check The New Custom Field on the Upload Form

Now, go to the product upload form. Here you can see the new field after that tag field –

You can add the product ID using this new field to differentiate the products further.

Step 4: Display New Field Data on a Single Product Page

Now you may want to show new field data on your single product page. The last part of the code helps you to do this. To serve this purpose we’ve used the action- 

woocommerce_single_product_summary

You can make some changes to the code we’ve included above if you need to add more fields on your Dokan product page.
