So, it simply turns out that the method I usually use to save post meta doesn’t work in this context, even though it does in when using the classic editor. I don’t know why this is, but I did find another article (https://www.codeinwp.com/blog/make-plugin-compatible-with-gutenberg-sidebar-api/) and there was a line in there that eventually led me to … Read more
Block Style Variations allow providing alternative styles to existing blocks using filters, as explained here. Here are some examples for your case using the server-side functions (php). You can either add the css style inline: register_block_style( ‘core/html’, array( ‘name’ => ‘full-width-video’, ‘label’ => __( ‘Full Width Video’ ), ‘inline_style’ => ‘.wp-block-html.is-style-full-width-video { width:100%; }’, ) … Read more
That is not how blocks work. If you want to save something, it must be a block attribute. withState lets a function have internal state, so it’s useful if you want to add toggle controls to your blocks UI, but it should not be used to store things that need to be saved. So you … Read more
You’ll need to use the REST API. You can access the latest posts by calling: wp.apiFetch( { path: ‘/wp/v2/posts’ } ).then( posts => { console.log( posts ); } ); Here is some more information on using the package – https://developer.wordpress.org/block-editor/packages/packages-api-fetch/
That documentation is for the base ButtonBlockAppender component in the @wordpress/block-editor package, and that component is exported with the name ButtonBlockerAppender (note the “Blocker” vs “Block”). But your code is actually using InnerBlocks.ButtonBlockAppender which is an enhanced version of that base ButtonBlockAppender component, and as of writing, that enhanced version does not include the className … Read more
It’s called when the component is first rendered, then again when the dependencies declared in the second parameter change: deps Array: If provided, this memoizes the mapSelect so the same mapSelect is invoked on every state change unless the dependencies change. So don’t pass that array, and it will work as you expected.
Yes, you have to use the init hook if you want to use add_theme_support from a plugin. I’ve tested the below code as a plugin and worked for me. <?php /* Plugin name: Add Color Palette */ function mytheme_setup_theme_supported_features() { add_theme_support(‘editor-color-palette’, array( array( ‘name’ => esc_attr__(‘Strong magenta’, ‘themeLangDomain’), ‘slug’ => ‘strong-magenta’, ‘color’ => ‘#a156b4’, ), … Read more
This whole block variations thing is a complete red herring, a wild goose chase! But lets just follow it to its conclusion before I share the actual solution, which is much simpler than you’d think. You wouldn’t look at the variation itself, variations set different attributes, and it’s the attributes you should look for, not … Read more
Glad that you managed to fix the 3rd issue (block validation failed), and as for the first and second issues, you can fix them by using useBlockProps in your block’s edit callback: // In src/index.js import { TextControl } from ‘@wordpress/components’; import { useBlockProps } from ‘@wordpress/block-editor’; export default function Edit( { attributes, className, setAttributes … Read more
One way of getting a unique id for a block in Gutenberg is using the clientId, but in a different way. Given that clientId string is used only once, you can store that in the attributes of the block, which will be stored in the database and you can retrieve it at any given time, … Read more
