In the context of WordPress, blockProps is an object that contains the properties (data) of a block.

Blocks are a fundamental concept in WordPress that allows users to add, arrange, and style content more visually and flexibly.

Each block has a unique property set that defines its behavior and appearance.

The user in the WordPress editor can set these properties, which are stored in the blockProps object.

For example, a “button” block might have text, color, and size properties, while a “quote” block might have properties such as author and alignment.

The blockProps object is used in the block’s render callback function, which is responsible for rendering the block’s content on the front end of the website.

The blockProps object is also used in the block’s edit function, which defines the block’s interface in the WordPress editor.

You can access the blockProps object within the render or edit functions by passing it as an argument to the function and then using it to access the block’s properties.

blockProps from render callback

In the context of a render callback in WordPress, blockProps refers to an object that contains a block’s properties (data). You can access blockProps within the render callback function like this:

function myRenderCallback( $attributes, $content, $block ) {
  $blockProps = $block['blockProps'];
  // Use the blockProps object to access the properties of the block
  $blockTitle = $blockProps['title'];
  // Use the blockTitle variable in your render callback function
  return '<h2>' . $blockTitle . '</h2>' . $content;
}

Remember that the structure and contents of the blockProps object will depend on the specific block you are working with and the properties you have defined for it.

You can also access the blockProps object from within the block’s edit function (the function that defines the block’s interface in the WordPress editor). The blockProps object is passed as an argument to the edit function and can be accessed like this:

function myBlockEdit( $props ) {
$blockProps = $props['blockProps'];
// Use the blockProps object to access the properties of the block
$blockTitle = $blockProps['title'];
// Use the blockTitle variable in your edit function
return '';
}
