Post_Template::get_column_count │ private │ WC 1.0

Determine how many columns the grid should render.

Prefers the block's own layout.columnCount attribute and falls back to the columns-N class WordPress core stamps on the rendered list, so it still works when the parsed attributes are sparse. Non-grid/flex layouts always resolve to a single (stacked) column.

Method of the class: Post_Template{}

No Hooks.

Returns

int. Column count (at least 1).

Usage

// private - for code of main (parent) class only
$result = $this->get_column_count( $parsed_block, $dom, $list_element ): int;

$parsed_block(array) (required)

Parsed block data.

$dom(Dom_Document_Helper) (required)

Parsed block content.

$list_element(DOMElement) (required)

The post-template list element.
