如何在单独的价值之外获得功能价值？

Question

public function addit() {
    $this->autoRender = false;
    if ($this->request->is('post')) {
        // $this->Products->addProduct($this->request->data['Cart']['product_id']);
        echo "".$this->Products->get($id);//for test
    } else {
        echo "".$this->Products->get($id);//for test
    }
 }

我想获取变量a的值是此函数之外的单独变量。 a的值来自另一个Controller类。

Answer 1

在方法外部声明一个变量，然后在方法内部更改该变量。

private static final String CREATE_SERIES_TABLE =
    "CREATE TABLE " + SERIES_TABLE + " (" +
            KEY_SERIE_ID + " LONG PRIMARY KEY, "
            + KEY_SERIE_PORTADA + " BLOB NOT NULL, "
            + KEY_SERIE_TITULO + " TEXT NOT NULL, "
              // Here ------------^
            + KEY_SERIE_AÑO + " INTEGER NOT NULL, "
              // Here ---------^
            + KEY_SERIE_GENERO + " TEXT NOT NULL, "
              // Here ------------^
            + KEY_SERIE_DESCRIPCION + " TEXT NOT NULL, "
              // Here -----------------^
            + KEY_SERIE_TEMPORADAS + " INTEGER NOT NULL"
              // Here ----------------^
            + ")";
