WP_Block_Patterns_Registry::register( string $pattern_name, array $pattern_properties ): bool

Registers a block pattern.

Parameters

$pattern_namestringrequired

Block pattern name including namespace.

$pattern_propertiesarrayrequired

List of properties for the block pattern.

title string
Required. A human-readable title for the pattern.
content string
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.
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.
inserter bool
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.
categories string[]
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.
keywords string[]
Optional. A list of aliases or keywords that help users discover the pattern while searching.
blockTypes string[]
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).
postTypes string[]
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.
templateTypes string[]
Optional. An array of template types where the pattern fits.
filePath string
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.
