აღწერა
Block Logic adds a “Block Logic” field to the “Advanced” section of the block editor (i.e Gutenberg), that lets you show or hide any block based on conditions. You can use WordPress’ Conditional Tags or any general PHP code.
Show or hide blocks based on
- User role
- User login status
- Post status
- Date and time
- The result of a custom PHP function
Features
- Show or hide any block using conditions
- Combine conditions with “and” or “or” operators. See FAQ Writing Logic Code
- Full flexibility: use any condition you want
Limitations
Does not work with the Classic Block, Widget Block or Widget Area Block [‘core/freeform’, ‘core/legacy-widget’, ‘core/widget-area’], as the those blocks do not support block attributes. Does also not work with the HTML Block [‘core/html’] inside the Widget Screen, as this one also does not support block attributes there.
Configuration
Just activate the plugin. The “Block Logic” textbox will then appear in the “Advanced” section of the Gutenberg editor.

Writing Logic Code
-
Make good use of WP’s own conditional tags. You can vary and combine code using:
!
(not) to reverse the logic, eg!is_home()
is TRUE when this is NOT the home page.||
(or) to combine conditions.X OR Y
is TRUE when either X is true or Y is true.&&
(and) to make conditions more specific.X AND Y
is TRUE when both X is true and Y is true.is_home()
— just the main blog page!is_page('about')
— everywhere EXCEPT this specific WP ‘page’is_user_logged_in()
— shown when a user is logged inis_category(array(5,9,10,11))
— category page of one of the given category IDsis_single() && in_category('baked-goods')
— single post that’s in the category with this slugcurrent_user_can('level_10')
— admin only blocksstrpos($_SERVER['HTTP_REFERER'], "google.com")!=false
— blocks to show when clicked through from a google searchis_category() && in_array($cat, get_term_children( 5, 'category'))
— category page that’s a descendent of category 5global $post; return (in_array(77,get_post_ancestors($post)));
— WP page that is a child of page 77global $post; return (is_page('home') || ($post->post_parent=="13"));
— home page OR the page that’s a child of page 13
Note the extra ‘;’ on the end where there is an explicit ‘return’.

The ‘block_logic_eval_override’ filter
-
Before the Block Logic code is evaluated for each block, the text of the Block Logic code is passed through this filter. If the filter returns a BOOLEAN result, this is used instead to determine if the block is visible. Return TRUE for visible.
-
With great power comes great responsibility
-
The block logic you introduce is EVAL’d directly. Anyone who has access to use the Gutenberg Editor will have the right to add any code, including malicious and possibly destructive functions. There is an optional filter ‘block_logic_eval_override’ which you can use to bypass the EVAL with your own code if needed.
- I’m getting “PHP Parse error… … eval()’d code on line 1”
You have a PHP syntax error in one of your block’s “Block Logic” fields. Review them for errors.
