## ವಿವರಣೆ

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](https://codex.wordpress.org/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 (you can extend base functionality
   with filters)

### 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.

### Breaking changes since 2.0.0

Since version 2.0.0 the code does not get eval’d directly, but there is a whitelist
of allowed functions that can be extended via a filter.

### Upgrade Notice

When upgrading to version 2.x you will need to update your logic. No `return` is
allowed anymore and no semicolons in code as only expressions are evaluated. See
FAQ Section **Writing Logic Code**.

## FAQ

### Writing Logic Code

Make good use of [WP’s own conditional tags](https://codex.wordpress.org/Conditional_Tags).
Use operators to combine conditions. See Supported functions and globals section
for allowed functions. Functions are extendable via filters.

 1.  **Operators**
 2.   * `!` (not) to **reverse** the logic, eg `!is_home()` is TRUE when this is NOT
        the home page.
      * `||` (or) to **combine** conditions. `X || Y` is TRUE when either X or Y is
        true.
      * `&&` (and) to make conditions **more specific**. `X && Y` is TRUE when both
        X and Y are true.
 3.  **WordPress Conditional Checks**
 4.   * `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 in
      * `is_category(array(5,9,10,11))` — category page of one of the given category
        IDs
      * `is_single() && in_category('baked-goods')` — single post that’s in the “baked-
        goods” category
      * `current_user_can('administrator')` — admin-only blocks
      * `strpos($_SERVER['HTTP_REFERER'], "google.com") !== false` — blocks to show
        when clicked through from Google
      * `is_category() && in_array($cat, get_term_children(5, 'category'))` — category
        page that’s a descendant of category 5
      * `in_array(77, get_post_ancestors($post))` — WP page that is a child of page
        77
      * `is_page('home') || $post->post_parent == 13` — home page or the page that’s
        a child of page 13
 5.  **WordPress Post & Term Checks**
 6.   * `has_term('special-offer', 'category', $post)` — post has a specific category
        term
      * `get_post_meta(get_the_ID(), 'featured', true) == 'yes'` — check a meta field
        value
      * `get_post_type() == 'product'` — current post type is a WooCommerce product
      * `is_sticky()` — sticky posts only
      * `has_post_thumbnail()` — only posts/pages with a featured image
      * `get_the_category()` — fetch post categories (can be used in expressions)
      * `get_the_tags()` — fetch post tags
 7.  **WooCommerce-Specific Checks**
 8.   * `WC()->cart && WC()->cart->get_cart_contents_count() > 0` — cart has at least
        one item
      * `WC()->cart && WC()->cart->total > 50` — cart total is more than $50
      * `is_product() && get_post_meta(get_the_ID(), '_sale_price', true) !== ''` —
        product has a sale price
      * `is_product_category('shoes') && WC()->cart` — category page “shoes” and cart
        exists
      * `is_user_logged_in() && WC()->cart && WC()->cart->get_cart_contents_count()
        > 0` — logged-in user and cart has items
 9.  **ACF Checks (Read-only)**
 10.  * `get_field('featured') == true` — ACF field “featured” is true
      * `get_sub_field('discount') > 0` — ACF subfield “discount” has a value
      * `get_row() > 0` — there are ACF repeater rows
      * `get_field_object('product_info')['value'] !== ''` — check ACF field object
        value
 11. **PHP Helpers**
 12.  * `in_array('baked-goods', wp_get_post_categories($post))` — category array check
      * `strpos(get_permalink($post), 'sale') !== false` — check if permalink contains“
        sale”
      * `empty(get_post_meta(get_the_ID(), 'stock', true))` — post has no stock meta
      * `count(WC()->cart->get_cart()) > 1` — more than 1 item in cart
      * `time() > strtotime('2026-01-01')` — check current timestamp
      * `number_format(WC()->cart->total, 2)` — format cart total
      * `round(get_post_meta(get_the_ID(), 'rating', true)) > 4` — rating is greater
        than 4

### Supported functions and globals

Block Logic comes with a set of safe WordPress, WooCommerce, ACF, and PHP helper
functions, as well as selected globals and superglobals. These can be used in block
logic expressions to control the display of blocks dynamically.

 1.  **Allowed Superglobals**
 2.   * By default, only safe, read-only superglobals are available. Developers can
        extend this list via the `block_logic_allowed_superglobals` filter.

         - `$_POST` — submitted form data
         - `$_SERVER` — server/environment info (e.g., `$_SERVER['HTTP_REFERER']`)
         - `$_COOKIE` — cookies
      * Example usage:
      *     ```
            !empty($_GET['ref']) && strpos($_SERVER['HTTP_REFERER'], 'google.com') !== false
            ```
        
 3.  **Allowed WordPress Globals**
 4.   * These global variables are accessible inside block logic expressions. Extend
        the list via the `block_logic_allowed_globals` filter.

         - `$wp_query` — main query object
         - `$wp_the_query` — backup of main query

            ```
        

### Extending the list of allowed functions

Block Logic provides four filters that developers can use to safely extend which
functions, globals, and superglobals are available inside block logic expressions.

 1. **Add custom functions**
 2.  * Use the `block_logic_allowed_functions` filter to make additional functions 
       available in block logic expressions.
     * Example
     *     ```
           add_filter('block_logic_allowed_functions', function($allowed) {
               $allowed[] = 'my_cart_has_items';
               return $allowed;
           });
       
           function my_cart_has_items() {
               return WC()->cart && WC()->cart->get_cart_contents_count() > 0;
           }
           ```
       
     * Usage in a block logic field:
     *     ```
           my_cart_has_items()
           ```
       
 3. **Add extra superglobals**
 4.  * Use the `block_logic_allowed_superglobals` filter to allow additional superglobals
       like $_SESSION.
     * Example:
     *     ```
           add_filter('block_logic_allowed_superglobals', function($allowed) {
               $allowed[] = '_SESSION';
               return $allowed;
           });
           ```
       
     * Usage in a block logic field:
     *     ```
           !empty($_SESSION['special_offer'])
           ```
       
 5. **Add extra WordPress globals**
 6.  * Use the `block_logic_allowed_globals` filter to allow extra global variables.
     * Example:
     *     ```
           add_filter('block_logic_allowed_globals', function($allowed) {
               $allowed[] = 'my_global_data';
               return $allowed;
           });
       
           // Somewhere in your theme or plugin
           $GLOBALS['my_global_data'] = ['foo' => 'bar'];
           ```
       
     * Usage in a block logic field:
     *     ```
           $post->ID == my_global_data['foo']
           ```
       
 7. **Add completely custom globals**
 8.  * Use the `block_logic_extra_globals` filter to allow any additional global variable
       in block logic expressions.
     * Example:
     *     ```
           add_filter('block_logic_extra_globals', function($allowed) {
               $allowed[] = 'my_custom_flag';
               return $allowed;
           });
       
           // Initialize the global somewhere
           $GLOBALS['my_custom_flag'] = true;
           ```
       
     * Usage in a block logic field:
     *     ```
           $my_custom_flag && is_user_logged_in()
           ```

Beautiful plugin, solves many of my problems while being very light weight and efficient.
Many plugins try to solve too many things, probably because it motivates a price
tag. But when all you need is to solve a specific issue, plugins like this are a
god send.

This plugin is absolutely AWESOME! Simple, fast and efficient. No bloat with tons
of pre-configured conditions for every popular plugin out there, no fancy UI that’s
often not needed, etc. Definitely a part of my toolset now.
