Best way to output array from controller to view in laravel 5

Question

I currently have this in my view to output data from an array that comes from my controller:

<!DOCTYPE html>
<html>
  @foreach ($details as $detail)
  <head>
    <meta charset="utf-8">
    <title>{{ $detail->name }}</title>
  </head>
  <body>
    <h1>in view</h1>

      {{ $detail->name }}
      <br>
      {{ $detail->street }}
      <br>
      {{ $detail->city }}, {{ $detail->state }}. {{ $detail->zip }}


  </body>
    @endforeach
</html>

This is the function in my controller:

  $details = DB::table('restaurants')->where('id', $restaurant_id)->get();
  return view ('restaurant.detail')->with('details', $details);

My question is: is there a better way to do this? I tried using the blade syntax without the @foreach and didn't have any luck.

I don't want to output this multiple times, the only reason I have the foreach there is because it is the only way I could get it to output.

If this is how it is supposed to work, no worries, I am just not familiar enough yet with blade to know if there is a better way to output this.

Thank you!

You shouldnt be recreating entire HTML documents. What is it exactly you want? — ImAtWar

@ImAtWar first I had the foreach in just the body, but I wanted to be able to output the $detail->name in the <title>, therefore I just wrapped it around the full HTML doc to get that to work. I want to be able to output this array, but it only works with the foreach. Is there a way where I won't need that? — ddrossi93

Having the <!DOCTYPE html> and <html> elements inside a loop looks very wrong. A browser will probably only render one <html> document and ignore any subsequent ones. — apokryfos

@apokryfos correct. It will work if I move the foreach (fixed above), but is there a way to output the array without the need for the foreach loop? — ddrossi93

@Ddrossi93 technically speaking, no. However you can use one of the many functions that does the looping for you like e.g. $details->each(function ($detail) { /* do stuff */ }); — apokryfos

You seem to be selecting something by id, so that's probably unique. When you do ->get() by default it will return a collection of results because it assumes there's always a chance that there's more than 1. When selecting by ID however you know if something exists by that id, there's only going to be 1 of it. You can change the code to:

$detail = DB::table('restaurants')->where('id', $restaurant_id)->first();
return view ('restaurant.detail')->with('detail', $detail);

<html>
  <head>
    <meta charset="utf-8">
    <title>{{ $detail->name }}</title>
  </head>
  <body>
    <h1>in view</h1>

      {{ $detail->name }}
      <br>
      {{ $detail->street }}
      <br>
      {{ $detail->city }}, {{ $detail->state }}. {{ $detail->zip }}


  </body>
</html>

I highly recommend you look into Eloquent

Example of an eloquent model:

class Restaurant extends Model {} //The table name for model "Restaurant" is assumed to be restaurants

Then you can find a single restaurant:

$detail = Restaurant::find($restaurant_id);

Thanks again. I'll start digging more into Eloquent

Why do you want multiple title tags in your page ? It doesn't make any sense.

<!DOCTYPE html>
<html>
  <head>
    <meta charset="utf-8">
    <title><!-- What do you want to show here ? --></title>
  </head>
  <body>
    <h1>in view</h1>
        @foreach ($details as $detail)
            {{ $detail->name }}
            <br>
            {{ $detail->street }}
            <br>
            {{ $detail->city }}, {{ $detail->state }}. {{ $detail->zip}}
        @endforeach
  </body>
</html>

I don't want multiple title tags. The $detail->name will not work unless it is within the foreach loop. That is my question. Is there a way to do it without the foreach

Neabfi Over a year ago

Is there always one element in your array ?

Neabfi Over a year ago

In your controller just put $detail = details[0] or $detail = current(details). Pass $detail to your view then in your view simply do $detail->name.

If there are two elements in your array wich one do you want to show in your title tag ?

I added the code from my controller function above to assist you.

You can achieve this by below methods,

1. Use first() to retrieve single record like below,

// Controller Code
$detail = DB::table('restaurants')->where('id', $restaurant_id)->first();

<!-- View Code -->
<title>{{ $detail->name }}</title>

2. Use find() to retrieve single record by its primary key like below. It works similar to first() but it retrieves data by its primary key.

// Controller Code
$detail = DB::table('restaurants')->find($restaurant_id);

<!-- View Code -->
<title>{{ $detail->name }}</title>

3. You can use get() as you did in your question but you need to access it as array with 0th index. I assumed that your query will retrieve only one record. It won't fail even if it retrieves multiple records but you will only first record in your view.

// Controller Code
$details = DB::table('restaurants')->where('id', $restaurant_id)->get();

<!-- View Code -->
<title>{{ $detail[0]->name }}</title>

There could be some more approaches but I used only these approaches so far.
