使用路由方法时，参数未传递到laravel中的控制器方法

Question

I have the following code in my anchor tag in my laravel application:

<a href="{{ route('showQualityResult' , compact(Session::get('quality-data'))) }}">Submited Quality Check</a>

My route is set to run the following method when clicked on the above link:

public function showQualityResult($qualityData) {
        return $qualityData;
        // return view('quality-result' , compact($qualityData));
    }

Now when i click on the link, i get the following error:

Why am i getting a Missing argument 1 error when i clearly am passing data as a parameter in the tag like so below:

<a href="{{ route('showQualityResult' , compact(Session::get('quality-data'))) }}">Submited Quality Check</a> 

Why is the parameter not being passed to the method ?

Answer 1

Your route from your previous question:

Route::get('/showQualityResult', 'QualityCheckController@showQualityResult');

To pass the parameter, you should define it. So, it'll look like this:

Route::get('showQualityResult/{data}', 'QualityCheckController@showQualityResult');

And showQualityResult() method should accept it:

public function showQualityResult($data)
{
    ....

I'd recommend you to read the docs to understand how it works.
