Per the Block Patterns documentation in the Block Editor Handbook, the $pattern_properties array includes:
and the example function given is:
register_block_pattern( 'wpdocs-my-plugin/my-awesome-pattern', array( 'title' => __( 'Two buttons', 'wpdocs-my-plugin' ), 'description' => _x( 'Two horizontal buttons, the left button is filled in, and the right button is outlined.', 'Block pattern description', 'wpdocs-my-plugin' ), 'content' => "<!-- wp:buttons {\"align\":\"center\"} -->\n<div class=\"wp-block-buttons aligncenter\"><!-- wp:button {\"backgroundColor\":\"very-dark-gray\",\"borderRadius\":0} -->\n<div class=\"wp-block-button\"><a class=\"wp-block-button__link has-background has-very-dark-gray-background-color no-border-radius\">" . esc_html__( 'Button One', 'wpdocs-my-plugin' ) . "</a></div>\n<!-- /wp:button -->\n\n<!-- wp:button {\"textColor\":\"very-dark-gray\",\"borderRadius\":0,\"className\":\"is-style-outline\"} -->\n<div class=\"wp-block-button is-style-outline\"><a class=\"wp-block-button__link has-text-color has-very-dark-gray-color no-border-radius\">" . esc_html__( 'Button Two', 'wpdocs-my-plugin' ) .

As an addition to the category, I would like to give an example for those who did not know what syntax to use. Since a block pattern can be assigned to multiple categories you can use an array to place it in the right category. example:
register_block_pattern( 'wpdocs-my-plugin/my-awesome-pattern', array( 'title' =&gt; __( 'Two buttons', 'wpdocs-my-plugin' ), 'description' =&gt; _x( 'Two horizontal buttons, the left button is filled in, and the right button is outlined.', 'Block pattern description', 'wpdocs-my-plugin' ), 'content' =&gt; &quot;&lt;!-- wp:buttons {&quot;align&quot;:&quot;center&quot;} --&gt;n&lt;div class=&quot;wp-block-buttons aligncenter&quot;&gt;&lt;!-- wp:button {&quot;backgroundColor&quot;:&quot;very-dark-gray&quot;,&quot;borderRadius&quot;:0} --&gt;n&lt;div class=&quot;wp-block-button&quot;&gt;&lt;a class=&quot;wp-block-button__link has-background has-very-dark-gray-background-color no-border-radius&quot;&gt;&quot; . esc_html__( 'Button One', 'wpdocs-my-plugin' ) . &quot;&lt;/a&gt;&lt;/div&gt;n&lt;!-- /wp:button --&gt;nn&lt;!-- wp:button {&quot;textColor&quot;:&quot;very-dark-gray&quot;,&quot;borderRadius&quot;:0,&quot;className&quot;:&quot;is-style-outline&quot;} --&gt;n&lt;div class=&quot;wp-block-button is-style-outline&quot;&gt;&lt;a class=&quot;wp-block-button__link has-text-color has-very-dark-gray-color no-border-radius&quot;&gt;&quot; . esc_html__( 'Button Two', 'wpdocs-my-plugin' ) . &quot;&lt;/a&gt;&lt;/div&gt;n&lt;!-- /wp:button --&gt;&lt;/div&gt;n&lt;!-- /wp:buttons --&gt;&quot;, 'categories' =&gt; ['custom_category', 'columns'], ) );how to define/register a category can be found here: https://developer.wordpress.org/reference/functions/register_block_pattern_category/ — By MangoWambo —
The docs & handbook don’t seem to mention it, but I gather
register_block_pattern()should be called from a handler attached to theinithook.function wpdocs_register_my_patterns() { register_block_pattern( ... ); } add_action( 'init', 'wpdocs_register_my_patterns' );Feedback
Good call! Registering the block pattern straight from functions.php results in the editor crashing with an obscure JS error after opening the patterns pannel, without any PHP errors or warnings being triggered. Calling
register_block_patterninside the init hook solves this perfectly! Thanks! — By Jules Colle —If the core block patterns are removed via:
Make sure that there is at least one block pattern category registered. The block editor crashes if none are present.
