2佈局在一個控制器

Question

我在HomeController.php

// other pages layout 
protected $layout = "layout"; 

protected $layout2 = "layout2"; 
    // empty user object 
protected $user; 

// constructor 
public function __construct() 
{ 
} 


public function getAbout() 
{ 

// share main home page only 
$this->layout->content = View::make('about'); 

} 

// THIS IS NOT WORKING >>>> 
public function getAboutnew() 
{ 

// share main home page only 
$this->layout2->content = View::make('about'); 

} 

所以getAboutNew我想使用佈局2，但我得到了一個錯誤：

ErrorException (E_UNKNOWN) Attempt to assign property of non-object

如何解決這一問題？

Answer 1

您需要更改，HomeController的擴展名。 在你BaseController您有：

protected function setupLayout() 
{ 
    if (! is_null($this->layout)) 
    { 
     $this->layout = View::make($this->layout); 
    } 
} 

此轉換$this->layout（字符串）到您需要的視圖對象。

修正：

// BaseController, returning respective views for layouts 
protected function setupLayout() 
{ 
    if (! is_null($this->layout)) 
    { 
     $this->layout = View::make($this->layout); 
    } 

    if (! is_null($this->layout2)) 
    { 
     $this->layout2 = View::make($this->layout2); 
    } 
} 



// HomeController 
public function getAbout() 
{ 
    $this->layout->content = View::make('about'); 
} 


public function getAboutnew() 
{ 
    $this->layout2->content = View::make('about'); 
    return $this->layout2; 
    // Note the additional return above. 
    //You need to do this whenever your layout is not the default $this->layout 
}
