问题描述
我有一段代码，我试图找出为什么一个变体有效而另一个无效.
I have a piece of code and I'm trying to find out why one variation works and the other doesn't.
return View::make('gameworlds.mygame', compact('fixtures'), compact('teams'))->with('selections', $selections);
这让我可以按预期生成赛程、球队和选择的数组视图.
This allows me to generate a view of arrays for fixtures, teams and selections as expected.
然而，
return View::make('gameworlds.mygame', compact('fixtures'), compact('teams'), compact('selections'));
不允许正确生成视图.我仍然可以回显数组并获得预期的结果，但视图在到达选择部分后不会呈现.
does not allow the view to be generated properly. I can still echo out the arrays and I get the expected results but the view does not render once it arrives at the selections section.
没关系，因为我让它使用 ->with() 语法，但只是一个奇怪的语法.
It's oké, because I have it working with the ->with() syntax but just an odd one.

推荐答案
View::make 函数采用 3 个参数，根据文档是:
The View::make function takes 3 arguments which according to the documentation are:
public View make(string $view, array $data = array(), array $mergeData = array())
在您的情况下， compact('selections') 是 4th 参数.它不会传递给视图，并且 laravel 会抛出异常.
In your case, the compact('selections') is a 4th argument. It doesn't pass to the view and laravel throws an exception.
另一方面，您可以使用 with() 任意次数.因此，这将起作用:
On the other hand, you can use with() as many time as you like. Thus, this will work:
return View::make('gameworlds.mygame')
->with(compact('fixtures'))
->with(compact('teams'))
->with(compact('selections'));
这篇关于laravel compact() 和 ->with()的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持跟版网！
