I have a route like this:
web.php
Route::get('post/{slug}', [
'as' => 'post.single',
'uses' => 'PageController@getSingle',
]);
PageController.php
public function getSingle($slug)
{
//some db stuff and returning an array to view
return view('single', array('var1' => $var, 'var2' => $var2));
}
A post has a slug which is stored in the database. If a post exists with slug, example: first-post
Then the route mysite.com/post/first-post
works as expected. But if a post doesn't exists, example: second-post
Then the route mysite.com/post/second-post
gives me an error:
**ErrorException**
Trying to get property of non-object
I want it to show a 404 error page (404 page is already configured) mysite.com/hellohello
gives and 404 page, so it's working as expected.
Any suggestion what should I do?
Eloquent has a neat firstOrFail
method which either returns the first entity it finds, or if there is none throws an ModelNotFoundException which laravel converts to a 404 page.
public function getSingle($slug)
{
$var = YourModel::where('slug', $slug)->firstOrFail();
return view('single', compact('var'));
}
I think you should update your function like: And you can not close bracket in return view
public function getSingle($slug)
{
//some db stuff and returning an array to view
return view('single', array('var' => $var));
}
UPDATE after OP change the question content :
public function getSingle($slug)
{
//some db stuff and returning an array to view
$var = SOMEDBRESULT1;
$var2 = SOMEDBRESULT2;
return view('single', array('var1' => $var, 'var2' => $var2));
}
