Registers a block pattern.

$pattern_name string Required

Block pattern name including namespace.

$pattern_properties array Required

List of properties for the block pattern.

• titlestring
  Required. A human-readable title for the pattern.
• contentstring
  Required. Block HTML markup for the pattern.
• descriptionstring
  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.
• viewportWidthint
  Optional. The intended width of the pattern to allow for a scaled preview within the pattern inserter.
• categoriesarray
  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.
• blockTypesarray
  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).
• keywordsarray
  Optional. A list of aliases or keywords that help users discover the pattern while searching.

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