Block Logic – Full Block Display Control vs Content Visibility for Divi Builder

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 (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.

Content Visibility for Divi Builder allows Sections and Modules to be displayed/hidden based on the outcome of a PHP boolean expression. This plugin is for both the standalone Divi theme (or child themes thereof) and the Divi Builder plugin, version 3 or higher! Developer Filters Expression Validation Filters The following filters allow developers to customize expression validation behavior. Add these filters in your theme’s functions.php or in a custom plugin. content_visibility_for_divi_builder_blocked_functions Filter the array of blocked function names. Functions in this list will cause an expression to fail validation. All comparisons are case-insensitive. Example – allow file_get_contents (blocked by default): add_filter( 'content_visibility_for_divi_builder_blocked_functions', function( $functions ) { return array_diff( $functions, array( 'file_get_contents' ) ); } ); Example – block an additional function: add_filter( 'content_visibility_for_divi_builder_blocked_functions', function( $functions ) { $functions[] = 'my_dangerous_function'; return $functions; } ); content_visibility_for_divi_builder_allowed_tokens Filter the array of allowed PHP token types (T_* constants). Tokens not in this list will cause an expression to fail validation. This is an advanced filter – consult the PHP tokenizer documentation before modifying. Example – allow the T_VARIABLE token type (blocked by default, use with caution): add_filter( 'content_visibility_for_divi_builder_allowed_tokens', function( $tokens ) { $tokens[] = T_VARIABLE; return $tokens; } ); content_visibility_for_divi_builder_allowed_chars Filter the array of allowed single-character tokens. Characters not in this list (such as =, ;, {, }, `, @, &, |, ~, ^) will cause an expression to fail validation. Example – allow the & character for bitwise operations: add_filter( 'content_visibility_for_divi_builder_allowed_chars', function( $chars ) { $chars[] = '&'; return $chars; } ); content_visibility_for_divi_builder_allowed_callables Filter the array of callables (function names and Class::method static-method entries) the validator considers known-safe. Anything not on the allowlist (and not on the blocked_functions denylist) is treated as an “Unknown callable” error. Names are normalized (leading \ stripped, namespace\ keyword prefix stripped, lowercased) before comparison, so \My\Namespace\Class::method, My\Namespace\Class::method, and namespace\My\Namespace\Class::method all match the same allowlist entry. The default list ships with WordPress conditional tags (is_user_logged_in, current_user_can, is_admin, etc.). The Expression Validation tab’s content scanner generates a ready-to-paste snippet for this filter pre-populated with every custom callable currently in your content. Example – allowlist a theme helper and a static service method: add_filter( 'content_visibility_for_divi_builder_allowed_callables', function( $callables ) { $callables[] = 'mytheme_should_be_visible'; $callables[] = 'MyTheme\Visibility\Service::checkUser'; return $callables; } );
