Displaying an array element in a View - Laravel

Question

I am trying to output a variable like this: <h1>{{ $unitcode }}</h1>

I have this code making that variable:

        // Validation was successful.
        $inputcode = Input::get('unitcode');
        // First validation is successful. Next to check that it is a correct unit code.
        $unitcode = DB::table('unitcodes')->where('unitcode', $inputcode)->first();

       if(!$unitcode) {
           // Input code is wrong. The unit does not exist.
            return Redirect::route('get-buy')
                ->with('global', 'That unit code does not exist. Try again.');
       } else {
           // Success! Unit code exists!
            return View::make('showbooks')
                ->with('unitcode', $unitcode);
       }

When I run everything it gives me this: ErrorException (E_UNKNOWN) Array to string conversion (View: ..BLAH goes on to display path to view.

How can I get it to display the variable I want that was pulled from the DB?

Thanks!

In Laravel's DB abastraction layer a row from a database table (result of a SELECT ... LIMIT 1 - DB::...->first()) is an array. You can send any kind of variables using View::...->with but you need to use them properly in the template itself ('showbooks'). You most probably are doing a {{{ unitcode }}} in the template which is actually similar to executing an echo $unitcode. Now if $unitcode is an array and echo requires a string then PHP automatically tries to convert it and fails (ErrorException (E_UNKNOWN) Array to string conversion...). What you need to do is use it correctly:

{{{ unitcode['unitcode'] }}}

And this will work because $unitcode is a key-value dictionary where each key is a column from the DB table with its associated value.
