Customize and extend Google Structured Data extension with PHP code.
onGSDSchemaBeforeGenerate
This event fires immediately before the generation of the JSON-LD script that will be injected into the <head> of the page. It passes the $schema array variable by reference which includes all the schema properties. This is rather useful when you want to modify a schema property with a value fetched from the database or another extension.
Parameters
| $schema | (array) The schema.org properties |
| $data | (object) The structured data item as configured in the backend |

public function onGSDSchemaBeforeGenerate(&$schema, $data)
{
$schema['myProperty'] = 'myValue';
}
