* @type string $title Required. A human-readable title for the pattern.
|
|
* @type string $content Optional. Block HTML markup for the pattern.
|
|
* If not provided, the content will be retrieved from the `filePath` if set.
|
|
* If both `content` and `filePath` are not set, the pattern will not be registered.
|
|
* @type string $description 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.
|
|
* @type int $viewportWidth Optional. The intended width of the pattern to allow for a scaled
|
|
* preview within the pattern inserter.
|
|
* @type bool $inserter Optional. Determines whether the pattern is visible in inserter.
|
|
* To hide a pattern so that it can only be inserted programmatically,
|
|
* set this to false. Default true.
|
|
* @type string[] $categories 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.
|
|
* @type string[] $keywords Optional. A list of aliases or keywords that help users discover
|
|
* the pattern while searching.
|
|
* @type string[] $blockTypes 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`).
|
|
* @type string[] $postTypes Optional. An array of post types that the pattern is restricted
|
|
* to be used with. The pattern will only be available when editing one
|
|
* of the post types passed on the array. For all the other post types
|
|
* not part of the array the pattern is not available at all.
|
|
* @type string[] $templateTypes Optional. An array of template types where the pattern fits.
|
|
* @type string $filePath Optional. The full path to the file containing the block pattern content.
|
|
* }
|
|
* @return bool True if the pattern was registered with success and false otherwise.
