Woocommerce – How to add a link for a popup window when user selects a particular variation

I’m using PopupMaker plugin for wordpress to create the popup up. This works by using a click trigger on a css selector of your choosing.

With this line of code I can output the variations for the particular product when I’m on its single product page. 

    add_action( 'woocommerce_before_add_to_cart_quantity', 'dump_attributes' );

function dump_attributes() {
  global $product;
  var_dump($product->get_attribute('size'));
 }

I need to output a click-able link only when the customer selects a certain variation from the drop down.

The problem I have is generating that link only when a user selects the variation ‘Drum’.

    Figured out one way to solve it using jQuery and getting the ID of the selection drop down (there were two different ID's named after the attribute slug #size & #pa_size).

     add_action( 'woocommerce_before_add_to_cart_quantity', 'add_link_on_selection' );

function add_link_on_selection() {
?>
<script>

jQuery(document).ready(function ($) {
  $('#size, #pa_size').change(function(){
    if($('#add').length) {
        $('#add').remove();
        return;

} else {
  $selection = $(this).val().toLowerCase();
  console.log($selection);
$(this).after(
  '<div>' +
  ($selection == 'drum' ? '<a href="#"><div id="add">Freight Restrictions</div></a>' : '')  +
  '</div>'
);
}
  })
});
</script>
<?php

}

    I was able to give this a little more thought. First, we need to give the variation data that Woo sends via JSON a little extra value. I’m checking for a “black” color attribute:

    if( 'black' === strtolower($variation->get_attribute('color')) ){

    But you will want to change to suit your size attribute.

    Next, I define the link as

    $kia_data['custom_link'] = sprintf( '<a href="google.com">%s</a>', __( 'Your Link', 'your-textdomain' ) );

    This is just a link to google and so you’ll need to change that.

    Next, we add an empty <div> placeholder. And finally we load some scripts on variable products and listen for the found_variation event. When we get it, we get the variation from the JSON data and we can check for the custom_link we defined earlier and dump it into the empty holder <div>.

    That’s probably clear as mud, but here’s the full code snippet:

    /**
 * Add data to json encoded variation form.
 *
 * @param  array $data - this is the variation's json data
 * @param  object $product
 * @param  object $variation
 * @return array
 */
function kia_available_variation( $data, $product, $variation ){
    if( 'black' === strtolower($variation->get_attribute('color')) ){
        $kia_data['custom_link'] = sprintf( '<a href="google.com">%s</a>', __( 'Your Link', 'your-textdomain' ) );
    } else {
        $kia_data['custom_link'] = false;
    }

    return array_merge( $data, $kia_data );

}
add_filter( 'woocommerce_available_variation', 'kia_available_variation', 10, 3 );

/**
 * holder for display link
 */
function kia_custom_varition_link() {
    echo '<div class="woocommerce-variation-link"></div>';
}
add_action( 'woocommerce_single_variation', 'kia_custom_varition_link', 5 );


/**
 * Add scripts to variable products.
 */
function kia_on_found_template_for_variable_add_to_cart() {
    add_action( 'wp_print_footer_scripts', 'kia_variable_footer_scripts' );
}
add_action( 'woocommerce_variable_add_to_cart', 'kia_on_found_template_for_variable_add_to_cart', 30 );


function kia_variable_footer_scripts() {
    ?>
    <script type="text/javascript">
        jQuery( document ).ready(function($) {
            $('form.cart')
.on('found_variation', function( event, variation ) {
    if ( variation.custom_link ) {
        $link_html = variation.custom_link;
        $(this).find( '.woocommerce-variation-link' ).html( $link_html ).show();
    } else {
        $(this).find( '.woocommerce-variation-link' ).html('').hide();
    }

 }).on('reset_variation', function( event, variation ) {
    $(this).find( '.woocommerce-variation-link' ).html('').hide();
 });
        });
    </script>
<?php

}
