Something to scrap the head around. I’m creating a GB-Block which fetches Reviews (=posts) from a CPT. For some reason I thought it’s a cool Idea to show the posts in a flex/grid Layout on the frontend and to avoid missunderstanding (that something can be edited for example) I thought it would be cool to show a message in the backend (=editor) saying that this block shows dynamically all reviews on the frontend. So what I did is the following: 1. Creating my structure and add the Block-Action in PG 2. Add the “PHP Code” Action to that block calling a function, lets call it `showReviews()` and ticked “echo” to true 3. the function looks like the following: 3.1 If-Condition which returns something like `
See on frontend
` 3.2 Fetch all Posts from CPT 3.3 Output them in a Loop If 3.1 is true the function returns and doesn’t go to 3.2 & 3.3 … However, I found it quite tricky to impossible to check if the User is inside the block\_editor or on the frontend! I think it is about when the block code get’s fired, but I’m not that deep into Block-Development yet to know how to work around that. **What I’ve tried is the following:** ```auto if(is_admin()) return //alert-message ``` ```auto if(!is_admin()) { //regular output } return //alert-message ``` After some research I found out that wp\_admin() always returns false in block\_editor (so no option) **Current-Screen** > **[current\_screen | Hook | WordPress Developer Resources](https://developer.wordpress.org/reference/hooks/current_screen/)** > > Fires after the current screen has been set. Always returned an error (undefined) message. **$\_GET** Also tried to workaround with `if(isset($_GET['post']))`(for example) but that also didn’t work **So my question is:** Does anyone know a condition or faced a similar problem and can help out with the correct way to check inside the PHP-Code Action if I am inside the block-editor or not? TIA for your help! 😉 Cheers ---

That’s the code if someone wants to check it out. I’ve left out the current\_screen thing here, but that didn’t work either 😃 ```auto function createRezContent() { $backend = false; // Always returns false in Gutenberg (so no option) if (!is_admin()) { echo '######################### ADMIN'; } // didn't work if (isset($_GET['post']) || isset($_GET['post_type'])) { $backend = true; } // message to show if inside block-editor if ($backend) { return '

Hier werden im Frontend alle Bewertungen angezeigt!

'; } $args = [ 'post_type' => 'rezension', 'posts_per_page' => -1 ]; $rezensionen = get_posts($args); $output = ""; if (count($rezensionen) == 0) return; foreach ($rezensionen as $i => $rezension) { $icons = createStarIcons(); $ort = rwmb_meta('rezensionen_ort', '', $rezension->ID); $ort = 'aus ' . $ort; $name = get_the_title($rezension->ID); $firma = rwmb_meta('rezensionen_firma', '', $rezension->ID); $content = rwmb_meta('rezensionen_content', '', $rezension->ID); $output .= "
{$icons}

{$name} {$ort}

{$firma}

{$content}

"; } return $output; } ``` ---

May be load a custom js in gutenberg block editor that generates a snackbar alert stating these blocks are not editable or something. ```auto // Gutenberg editor customizations function wolfgang_enqueue() { wp_enqueue_script( 'wolfgang-gutenberg-editor', get_template_directory_uri() . '/assets/js/wolfgang-gutenberg-editor.js', ['wp-edit-post', 'wp-dom-ready'] ); } add_action('enqueue_block_editor_assets', 'wolfgang_enqueue_enqueue'); ``` ```auto const { select, subscribe, dispatch } = wp.data; const closeListener = subscribe( () => { const isReady = select( 'core/editor' ).__unstableIsEditorReady(); if ( ! isReady ) { // Editor not ready. return; } // Close the listener as soon as we know we are ready to avoid an infinite loop. closeListener(); // Your code is placed after this comment, once the editor is ready. }); ``` You can get the internal block id this way. ```auto select("core/block-editor").getBlocks().forEach(function(block, blockIndex){ if (block.name === "wolfgang/thistroublesomeblock"){ mycustomblock = block['clientId']; } }); ``` Then may be you track interactions with that particular block before generating snackbar alert?Not sure what will be an efficient way to track the particular block. ---

How about adding a class around the item wrapper and creating an editor stylesheet that just hides it? Then, you can create a div that is hidden on the front-end but viewable in the back-end alerting editors that the block will dynamically pull data. ---

> [@Pinegrow\_Learner](#): > > May be load a custom js in gutenberg block editor that generates a snackbar alert stating these blocks are not editable or something. Thanks for your Input @Pinegrow_Learner … I’ve thought about something similar too. My Girlfriend calls me “Toastmaster” since I always have the most imaginable fun implementing and creating different forms of snack/toastbars in my vue apps. But for some reason, I don’t like the approach of having a snackbar here, shame on me, I think the name is not justified! 😃 > [@adamslowe](#): > > How about adding a class around the item wrapper and creating an editor stylesheet that just hides it? Then, you can create a div that is hidden on the front-end but viewable in the back-end alerting editors that the block will dynamically pull data. Also thanks to you @adamslowe for your answer. That definitely goes in the right decision. If I’m not able to solve the problem programmatically with the right PHP Hook I will probably give that a try… But I would find it so neat if I could manipulate the output of any PHP Block. That would open the door to soo many use-cases in my opinion! I may have to revisit this topic when I have more time, but I really appreciate your point of views, many thanks for that!!
