Post_Template::find_post_template_list │ private │ WC 1.0

Locate the post-template list within the rendered content.

The list is matched by its wp-block-post-template class rather than by being the first <ul>, so a sibling list that happens to appear earlier in the markup can't be mistaken for the repeater. Returns null when no such list is present.

Method of the class: Post_Template{}

No Hooks.

Returns

\DOMElement|null.

Usage

// private - for code of main (parent) class only
$result = $this->find_post_template_list( $dom ): ?\DOMElement;

$dom(Dom_Document_Helper) (required)

Parsed block content.
