How to pass data to view in Laravel?
提问by Sam Pettersson
Im passing data to my blade view with return View::make('blog', $posts);and in my blade view I'm trying to run an @foreach ($posts as $post)I end up with an error saying that $postsisn't defined.
我将数据传递给我的刀片视图，return View::make('blog', $posts);并在我的刀片视图中我试图运行一个@foreach ($posts as $post)我最终得到一个错误，说$posts没有定义。
My question is how would the $postsarray be called?
我的问题是如何$posts调用数组？

If you want to pass just one variableto view, you may use
如果你只想传递一个变量来查看，你可以使用
In Controller
在控制器中
return view('blog')->withTitle('Laravel Magic method.');
In view
在视图中
<div>
Post title is {{$title}}.
</div>
If you want to pass multiple variables to view, you may use
如果要传递多个变量来查看，可以使用
In Controller
在控制器中
return view('blog')->withTitle('Laravel magic method')->withAuthor('Mister Tandon');
In view
在视图中
<div>
Post title is {{$title}}.Author Name is {{$author}}
</div>

You can also pass an array as the second argument after the view template name, instead of stringing together a bunch of ->with()methods.
您还可以在视图模板名称之后传递一个数组作为第二个参数，而不是将一堆->with()方法串在一起。
return View::make('blog', array('posts' => $posts));
Or, if you're using PHP 5.4 or better you can use the much nicer "short" array syntax:
或者，如果您使用的是 PHP 5.4 或更高版本，则可以使用更好的“短”数组语法：
return View::make('blog', ['posts' => $posts]);
This is useful if you want to compute the array elsewhere. For instance if you have a bunch of variables that every controller needs to pass to the view, and you want to combine this with an array of variables that is unique to each particular controller (using array_merge, for instance), you might compute $variables(which contains an array!):
如果您想在其他地方计算数组，这很有用。例如，如果您有一堆变量，每个控制器都需要传递给视图，并且您想将其与每个特定控制器独有的变量数组（array_merge例如，使用）结合起来，您可能会计算$variables（其中包含数组！）：
return View::make('blog', $variables);
(I did this off the top of my head: let me know if a syntax error slipped in...)
（我做了这件事：如果出现语法错误，请告诉我......）

use TCG\Voyager\Models\Jobtype;
class FormController extends Controller
{
public function index()
{
$category = Jobtype::all();
return view('contact', compact('category'));
}
}
- use your model
- assign it to a variabel
- pass the object to the view Here is an example:
- 使用你的模型
- 将它分配给一个变量
- 将对象传递给视图 这里是一个例子：

controller:
控制器：
use App\your_model_name;
funtion index()
{
$post = your_model_name::all();
return view('index')->with('this_will_be_used_as_variable_in_views',$post);
}
index:
指数：
<h1> posts</h1>
@if(count($this_will_be_used_as_variable_in_views)>0)
@foreach($this_will_be_used_as_variable_in_views as $any_variable)
<ul>
<p> {{$any_variable->enter_table_field}} </p>
<p> {{$any_variable->created_at}} </p>
</ul>
@endforeach
@else
<p> empty </p>
@endif
Hope this helps! :)
希望这可以帮助！:)

回答by Sagar jadhav
You can also do like this
你也可以这样做
$arr_view_data['var1'] = $value1;
$arr_view_data['var2'] = $value2;
$arr_view_data['var3'] = $value3;
return view('your_viewname_here',$arr_view_data);
And you access this variable to view as $var1,$var2,$var3
并且您访问此变量以查看为$var1, $var2,$var3

You can also write for passing multiple data from your controller to a view
您还可以编写将多个数据从控制器传递到视图
return \View::make('myHome')
->with(compact('project'))
->with(['hello'=>$hello])
->with(['hello2'=>$hello2])
->with(['hello3'=>$hello3]);
