Global helper functions

Global Helper Functions

To optimize developer experience and eliminate redundant boilerplate, global helper functions have finally been integrated. These helpers offer immediate and consistent access to core framework components and services. All previously available methods remain fully supported to ensure seamless backward compatibility.

zubzet()

Returns the main instance of the ZubZet framework.

Syntax: zubzet()

model()

Provides direct access to a specific model instance.

Syntax: model(string $modelName)

  • $modelName: The name of the model to be instantiated.

Note: In controller actions, $reqObj->getModel($modelName) remains a supported alternative.

Example:

model("Test")->onTest();

request()

Accesses the instance of the current request.

Syntax: request()

Example:

request()->getPost("POST_PARAMETER");

response()

Accesses the instance of the current response.

Syntax: response()

Example:

response()->sendEMail($to, $subject, $document);

config()

Retrieves a configuration value by its key.

Syntax: config(string $key, bool $useDefault = false, mixed $default = null)

  • $key: The configuration identifier.
  • $useDefault: Whether to return a fallback value if the key is not found.
  • $default: The value to return if $useDefault is true and the key is missing.

Note: Previously accessible via $req->getBooterSettings(...) inside controller actions; this approach remains fully supported.

Example:

config("db_username");

user()

Returns the instance of the currently authenticated user.

Syntax: user()

Note: This streamlines the previous method of calling $req->getRequestingUser() within controller actions.

Example:

user()->userId;

db()

Provides the database instance for a specified connection.

Syntax: db(string $connection = "default")

  • $connection: The name of the database connection (defaults to "default").

Note: Database access is no longer restricted to using $this->z_db within models.

Example:

db()->exec("SELECT * FROM z_user");

view()

Renders a view template directly.

Syntax: view(string $document, array $opt = [], array $options = [])

  • $document: The path to the view file.
  • $opt: Data array passed to the view.
  • $options: Additional rendering options.

Note: This serves as a streamlined alternative to rendering via the response object using $resObj->render(...).

Example:

view("adminpanel/dashboard");
