  • (string) $source_name The name of the source. It must be a string containing a namespace prefix, i.e. `my-plugin/my-custom-source`. It must only contain lowercase alphanumeric characters, the forward slash `/` and dashes.
    Requis: Oui
  • (array) $source_properties { The array of arguments that are used to register a source. @type string $label The label of the source. @type callback $get_value_callback A callback executed when the source is processed during block rendering. The callback should have the following signature: `function ($source_args, $block_instance,$attribute_name): mixed` - @param array $source_args Array containing source arguments used to look up the override value, i.e. {"key": "foo"}. - @param WP_Block $block_instance The block instance. - @param string $attribute_name The name of an attribute . The callback has a mixed return type; it may return a string to override the block's original value, null, false to remove an attribute, etc. @type array $uses_context (optional) Array of values to add to block `uses_context` needed by the source. }
    Requis: Oui
Retourne:
  • (WP_Block_Bindings_Source|false) Source when the registration was successful, or `false` on failure.

Registers a new block bindings source.

Registering a source consists of defining a name for that source and a callback function specifying how to get a value from that source and pass it to a block attribute. Once a source is registered, any block that supports the Block Bindings API can use a value from that source by setting its metadata.bindings attribute to a value that refers to the source. Note that register_block_bindings_source() should be called from a handler attached to the init hook. ## Example ### Registering a source First, you need to define a function that will be used to get the value from the source. function my_plugin_get_custom_source_value( array $source_args, $block_instance, string $attribute_name ) { // Your custom logic to get the value from the source. // For example, you can use the $source_args to look up a value in a custom table or get it from an external API. $value = $source_args['key']; return "The value passed to the block is: $value" } The $source_args will contain the arguments passed to the source in the block's metadata.bindings attribute. See the example in the "Usage in a block" section below. function my_plugin_register_block_bindings_sources() { register_block_bindings_source( 'my-plugin/my-custom-source', array( 'label' => __( 'My Custom Source', 'my-plugin' ), 'get_value_callback' => 'my_plugin_get_custom_source_value', ) ); } add_action( 'init', 'my_plugin_register_block_bindings_sources' ); ### Usage in a block In a block's metadata.bindings attribute, you can specify the source and its arguments. Such a block will use the source to override the block attribute's value. For example:

Fallback text that gets replaced.
