woocommerce: how to create a checkbox in the admin panel that will include a plugin

Анна Мороз :

I am creating a plugin that will change the look of the gallery in woocommerce. That is, instead of the gallery, an iframe will open. This works for all products.

add_filter( 'woocommerce_single_product_image_thumbnail_html', 'product_image');

function product_image(){
    $product = wc_get_product();
    $product_id = $product->get_id();
    $threedLink = 'http://sameurl/' .$product_id ;
    $content .= '<iframe src='.$threedLink.'  width="99%" height="300px"></iframe>';
    return $content;

}

But I need this to work not for all products, but for the chosen ones. That is, in the entire load of the product, you need to create a checkmark, where the administrator must agree to show the iframe. I created a tab in the product loading panel

function wk_custom_product_tab( $default_tabs ) {
    $default_tabs['custom_tab'] = array(
        'label'   =>  __( 'Custom Tab', 'domain' ),
        'target'  =>  'wk_custom_tab_data',
        'priority' => 60,
        'class'   => array()
    );
    return $default_tabs;
}

add_filter( 'woocommerce_product_data_tabs', 'wk_custom_product_tab', 10, 1 );

add_action( 'woocommerce_product_data_panels', 'wk_custom_tab_data' );

function wk_custom_tab_data() {
   echo '<div id="wk_custom_tab_data" class="panel woocommerce_options_panel">ddddd</div>';
}

how can I add a checkmark instead of ddddd and connect it with the plugin download?

• Add custom product tab
• Add content to the product tab (checkbox)
• Save the checkbox
• Get value, 'yes' or 'no' and if yes, display iframe
