Leon Stafford | Getting Snipcart custom data attributes into WordPress + Elementor Pricing Table

After shunning pagebuilders in WordPress long enough, I gave Elementor a try for a landing page layout and found it quite useful. I also realized how terribly far behind Gutenberg is!

So, Elementor got me 90% of the way there, as is often the case in WordPress - simple, until it isn’t!

function wp2static_snipcart_callback($buffer) {
   $html_output = $buffer;

   $dom = new DOMDocument();
   $dom->loadHTML($html_output);

   $finder = new DomXPath($dom);
   $classname="elementor-price-table__button";
   $nodes = $finder->query("//*[contains(@class, '$classname')]");

   $yearly_buy_button = $nodes->item(1);

   $yearly_buy_button->setAttribute('class','elementor-price-table__button elementor-button elementor-size-md snipcart-add-item');                                                                
   $yearly_buy_button->setAttribute('data-item-name','PowerPack, unlimited sites, yearly');
   $yearly_buy_button->setAttribute('data-item-id','powerpack-unlimited-yearly');
   $yearly_buy_button->setAttribute('data-item-url','https://securityandperformance.com/');
   $yearly_buy_button->setAttribute('data-item-price','99.00');
   $yearly_buy_button->setAttribute('data-item-payment-interval','Year');
   $yearly_buy_button->setAttribute('data-item-payment-interval-count','1');

   $unlimited_buy_button = $nodes->item(2);

   $unlimited_buy_button->setAttribute('class','elementor-price-table__button elementor-button elementor-size-md snipcart-add-item');                                                             
   $unlimited_buy_button->setAttribute('data-item-name','PowerPack, unlimited sites, lifetime');
   $unlimited_buy_button->setAttribute('data-item-id','powerpack-unlimited-lifetime');
   $unlimited_buy_button->setAttribute('data-item-url','https://securityandperformance.com/');
   $unlimited_buy_button->setAttribute('data-item-price','299.00');

   return $dom->saveHTML();
}

add_filter( 'the_content', 'wp2static_snipcart_callback' );
