Answers ( 1 )


    The get_dynamic_block_names() function in WordPress is a useful tool for developers working with dynamic blocks in the block editor. Here's a detailed explanation of its function and a sample usage:

    Function: get_dynamic_block_names()


    • Returns an array of the names of all registered dynamic block types.


    • This function is particularly useful when you need to identify or work with dynamic blocks programmatically. Dynamic blocks are blocks that render content based on changing information, usually from user inputs or external data sources.


    • Type: string[] (Array of strings)
    • Content: Each element in the array is a string representing the name of a registered dynamic block type.

    Sample Usage:


    Suppose you're developing a custom plugin or theme and you need to apply specific styles or scripts to all dynamic blocks.

    Code Sample:

    // Get all registered dynamic block names
    $dynamic_blocks = get_dynamic_block_names();
    // Loop through the dynamic block names
    foreach ($dynamic_blocks as $block_name) {
        // Perform operations with the dynamic block name
        // Example: Enqueue a script for each dynamic block


    1. Fetch Dynamic Blocks: First, we call get_dynamic_block_names() to get an array of all registered dynamic block names.
    2. Iterate Through Blocks: We then iterate through each block name using a foreach loop.
    3. Perform Operations: Inside the loop, you can perform various operations. In the example, for each dynamic block, we are enqueueing a custom script. This script could be tailored to modify or enhance the behavior of the dynamic blocks.

    Additional Notes:

    • This function is part of the WordPress Block Editor (Gutenberg) functionalities. It's crucial to ensure that your WordPress installation and your theme support Gutenberg to utilize this function effectively.
    • The returned names can be used to manipulate blocks, like adding custom attributes, applying styles, or even dynamically loading content based on the block's name.

    Remember, this function is mainly used by developers who are customizing or extending the WordPress block editor's capabilities.
