          </div>

          @endif
        @endforeach

      </div>
    </div> <!-- end .AN-SINGLE-COMPONENT -->

When I do dd($request->all()) I got all the data but when I click submit the error will occur.

Answer 1

This is not a Laravel specific error:

in php documents if you see

htmlspecialchars("<a href='test'>Test</a>", ENT_QUOTES);

this function accepts, 2 parameters, first one is a string and second is an optional parameter.

If you have an array of strings to be escaped then use foreach and escape each string

Answer 2

There is an array anywhere in one of your Blade {{}}, please check them.

Read: https://laravel.com/docs/5.6/blade#displaying-data

Answer 3

You are using Array inside {{}} somewhere. You can only use String inside {{}}.

use {{dd(variable_name)}} to check the variable before you use it inside {{}}. if its an array convert it into String first ( using implode()) ).
