Content Visibility for Divi Builder vs Wicked Block Conditions

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; } );

Wicked Block Conditions is a powerful tool for creating conditional blocks. A conditional block is a block that can be shown (or hidden) if the conditions you define are met. For example, you can create blocks that are only shown to logged-in users (great for membership sites). Define simple conditions or combine conditions into groups using and/or operators for more complex scenarios. Show or hide blocks based on: User login status User role Date and time Post categories or tags Post status The value of a query string parameter The result of a custom PHP function Features: Show or hide any block using conditions Specify an unlimited number of conditions Combine conditions with “and” or “or” operators Group conditions to create complex display rules Works with any Gutenberg block including third-party blocks Support Please see the FAQ section below for common questions.
