php - WooCommerce add data- attribute to view cart button on success message -

-

i've managed change html markup of view cart button on success message add id="open_cart" it, want add data- attribute such data-cart="open" html output, id returned.

any ideas on how add data- attribute it?

function my_add_to_cart_message() {     if ( get_option( 'woocommerce_cart_redirect_after_add' ) == 'yes' ) :      $message = sprintf( '%s<a id="open_cart" data-target="open-cart"  href="%s" class="button">%s</a>', __( 'successfully added cart.' , 'woocommerce' ), esc_url( get_permalink( woocommerce_get_page_id( 'cart' ) ) ), __( 'view cart', 'woocommerce' ) );      return $message;  } add_filter( 'wc_add_to_cart_message', 'my_add_to_cart_message' );

this function above returns:

<a id="open_cart" href="http://example.com/cart/" class="button wc-forward">ver carrinho</a>

the data-cart="open" ignored. annoying.

here's quick explanation why happening.

take @ woocommerce success.php template responsible displaying success messages.

<?php foreach ( $messages $message ) : ?>     <div class="woocommerce-message"><?php echo wp_kses_post( $message ); ?></div> <?php endforeach; ?>

the wp_kses_post() function sanitizes output of $message variable checking allowed tags , attributes.

here's solution:

add snippet functions.php

function my_filter_allowed_html($allowed, $context){     if (is_array($context)) {         return $allowed;     }      if ($context === 'post') {          $allowed['a']['data-cart'] = true;     }      return $allowed; } add_filter('wp_kses_allowed_html', 'my_filter_allowed_html', 10, 2);

you need hook wp_kses_allowed_html filter , add data attribute wp_kses_post() function doesn't filter out.
