WordPress can show different block choices according to a user’s capabilities. Filter allowed_block_types_all and check capabilities with current_user_can(). Prefer capabilities over hard-coded role names. Role-aware block lists guide editorial workflows. They do not secure block output or server actions. Sensitive operations still need authentication, capability checks, validation, and escaping. Combine user rules with post-type and…

Use the allowed_block_types_all filter to allow different blocks by post type. Read the current post from its editor context. Return an approved array for matching types. Keep the incoming value for contexts without a post. Preserve stricter upstream restrictions. Test templates, patterns, existing content, imports, and every supported custom type. This rule changes editor insertion…

The WordPress Block Manager is the Blocks section inside editor Preferences. It lets a user hide unwanted blocks from their inserter. Existing content and block registration remain intact. Use it when too many choices slow everyday writing. Hide duplicates, specialised blocks, and rarely used options. Reset the list whenever a missing choice becomes useful again.…

WordPress blocks can be hidden, restricted from insertion, unregistered, or removed with their provider. These actions have different effects. Choose the smallest action meeting the real requirement. Personal preferences simply clean one editor’s inserter. Server allow lists govern insertion by context. JavaScript unregistering removes client registration. Plugin deactivation can affect existing output. None of these…

Replacing a WordPress block across a site is a structured content migration. Do not rename delimiter text blindly. Attributes, saved HTML, nesting, and fallbacks can differ. First inventory every target instance. Then define an explicit source-to-destination mapping. Transform parsed blocks on staging, verify results, and preserve rollback. Small migrations may be safer manually. Large migrations…

WordPress has no single complete screen listing every use of one block. A reliable audit must scan stored block content across several locations. It must also follow shared references. Start with the block’s registered name, such as acme/notice. Search delimiter comments for candidates. Then parse those candidates and record exact locations. Include posts, pages, custom…

Deactivating a block plugin stops its code from running. Saved block content usually remains in the database. What visitors and editors see depends on the block architecture. Static blocks often leave saved HTML visible. Dynamic blocks may lose their generated output. Plugin styles, scripts, controls, variations, and transforms also disappear. Reactivation commonly restores registered blocks…

Server-side rendering generates a WordPress block’s frontend HTML during a request. PHP receives saved attributes and returns current markup. The database may store only a delimiter comment. This architecture suits changing data, shared markup, and server-only logic. Examples include latest posts, query results, login states, and calculated values. It also creates a runtime dependency. The…

WordPress stores block attributes according to each attribute’s declared source. Unsourced attributes enter the block’s comment JSON. Sourced attributes are extracted from saved HTML. Some modern blocks can also read separate entity data through bindings. Defaults may not be stored anywhere. Nested blocks remain document structure, not ordinary attributes. Therefore, there is no universal block-attribute…

WordPress block markup comments identify block boundaries inside saved content. They also store selected block attributes as JSON. Browsers ignore them, while WordPress reads their structure. Without these comments, saved HTML would lose reliable block identity. WordPress could guess from tags and classes. Those clues remain ambiguous and easily changed. The comments therefore preserve ordinary…
