El objeto context es una caracter\u00edstica t\u00e9cnica introducida en la versi\u00f3n 1.5 de Prestashop para evitar que los programadores empleen variables globales y sea m\u00e1s f\u00e1cil obtener informaci\u00f3n de contexxto en algunos controladores o m\u00f3dulos.<\/p>\n

El objeto context es un registro de las variables PHP que, en versiones anteriores de Prestashop se utilizaban como globales, como por ejemplo: $cookie, $smarty…<\/p>\n

El objetivo del objeto context es estandarizar el modo de acceso a estas variables haciendo que el c\u00f3digo sea m\u00e1s s\u00f3lido y f\u00e1cil de entender eliminando el uso de variables globales.<\/p>\n

En Prestashop 1.4 pod\u00edamos utilizar las variables globales para obtener informaci\u00f3n importante en un momento dado. Por ejemplo, para obtener el idioma que utiliza el cliente empleamos:<\/p>\n

\n
$cookie<\/code>->id_lang;<\/code><\/div>\n<\/div>\n

En Prestashop 1.5, la forma correcta de acceder a este valor es utilizar el objeto context:<\/p>\n

\n
$this<\/code>->context->language->id;<\/code><\/div>\n<\/div>\n

\u00a0Contenido del objeto context<\/h2>\n
    \n
  • Language<\/strong>. Lenguage del cliente o empleado.<\/li>\n
  • Country<\/strong>. Toda la informaci\u00f3n del pa\u00eds del cliente que est\u00e1 en linea.<\/li>\n
  • Currency<\/strong>. La moneda del cliente o la moneda de la tienda.<\/li>\n
  • Shop<\/strong>. Tienda actual.<\/li>\n
  • Cookie<\/strong>. Toda la informaci\u00f3n referente a la cookie o sesi\u00f3n establecida.<\/li>\n
  • Link<\/strong>. Instancia Link actual.<\/li>\n
  • Smarty<\/strong>. Instancia Smarty.<\/li>\n
  • Customer<\/strong>. Toda la nformaci\u00f3n referente al cliente en linea.<\/li>\n
  • Cart<\/strong>. Toda la informaci\u00f3n referente al carrito actual.<\/li>\n
  • Controller<\/strong>. Instancia del controlador actual.<\/li>\n
  • Employee<\/strong>. Empleado actual.<\/li>\n<\/ul>\n

    Desde cualquier clase o controlador podemos hacer uso del objeto context de la siguiente forma:<\/p>\n

    $this->context->...<\/code><\/pre>\n
    Tambi\u00e9n podemos capturar informaci\u00f3n del contexto en las plantillas .tpl de la siguiente forma:<\/p>\n
    Context::getContext()<\/code>->...<\/pre>\n
    Ejemplos:<\/p>\n
    $this->context->language->id; \/\/Retorna el identificador del lenguaje actual\r\n$this->context->language->iso_code; \/\/Retorna el identificador ISO del lenguaje actual\r\n$this->context->currency; \/\/Retorna el objeto moneda actual\r\n$this->context->link; \/\/Retorna el objeto link\r\n$this->context->country->id_zone; \/\/Retorna el identificador de la zona del cliente actual\r\nif ($this->context->customer->isLogged()) \/\/Comprobaci\u00f3n de si est\u00e1 el cliente logeado o no\r\nif ($this->context->employee->isLoggedBack()) \/\/Comprobaci\u00f3n de si est\u00e1 logeado el empleado administrador\r\n$this->context->cart->getProducts(); \/\/Retorna los productos que hay en la cesta actualmente\r\n$this->context->smarty->assign(...); \/\/Asignaci\u00f3n de variables smarty para la plantilla\r\n$this->context->customer->birthday; \/\/Retorna la fecha de nacimiento del cliente en linea\r\n$this->context->cms->id; \/\/Retorna el identficador de la p\u00e1gina cms que se est\u00e1 visualizando<\/pre>\n
    Como podemos ver toda la informaci\u00f3n de contexto?<\/h2>\n
    En cualquier controlador o clase podemos visualizar el array de objetos de la siguiente forma:<\/p>\n
    echo '<pre>';\r\nprint_r($this->context);\r\necho '<\/pre>';<\/pre>\n","protected":false},"excerpt":{"rendered":"
