WP_Block_Patterns_Registry::register()publicWP 5.5.0

Registers a block pattern.

{} It's a method of the class: WP_Block_Patterns_Registry{}

No Hooks.

Return

true|false. True if the pattern was registered with success and false otherwise.

Usage

$WP_Block_Patterns_Registry = new WP_Block_Patterns_Registry();
$WP_Block_Patterns_Registry->register( $pattern_name, $pattern_properties );
$pattern_name(string) (required)
Block pattern name including namespace.
$pattern_properties(array) (required)

List of properties for the block pattern.

  • title(string)
    Required. A human-readable title for the pattern.

  • content(string)
    Required. Block HTML markup for the pattern.

  • description(string)
    Optional. Visually hidden text used to describe the pattern in the inserter. A description is optional, but is strongly encouraged when the title does not fully describe what the pattern does. The description will help users discover the pattern while searching.

  • viewportWidth(int)
    Optional. The intended width of the pattern to allow for a scaled preview within the pattern inserter.

  • categories(array)
    Optional. A list of registered pattern categories used to group block patterns. Block patterns can be shown on multiple categories. A category must be registered separately in order to be used here.

  • blockTypes(array)
    Optional. A list of block names including namespace that could use the block pattern in certain contexts (placeholder, transforms). The block pattern is available in the block editor inserter regardless of this list of block names. Certain blocks support further specificity besides the block name (e.g. for core/template-part you can specify areas like core/template-part/header or core/template-part/footer).

  • keywords(array)
    Optional. A list of aliases or keywords that help users discover the pattern while searching.

Changelog

Since 5.5.0 Introduced.
Since 5.8.0 Added support for the blockTypes property.
