Laravel - how to calculate the sum of objects in an array in blade view

Question

I have a foreach loop in a blade view, where I am listing the objects that have a pivot property price:

                @foreach($transaction->options as $option)
                  <div class="row">
                    <div class="col-md-6">
                      <p>Option description: {{ $option->description }}</p>
                      <p>Price: {{ $option->pivot->price }}</p>
                    </div>
                  </div>
                  <hr>
                @endforeach
                <div class="row">
                  <div class="col-md-6">
                    <h4>Options total: </h4>
                  </div>
                </div>

I would like to since I am doing a foreach loop here, calculate the sum of all the options so that I could write it next to Options total:

I have tried with this:

               @foreach($transaction->options as $option)
                  <div class="row">
                    <div class="col-md-6">
                      <p>Option description: {{ $option->description }}</p>
                      <p>Price: {{ $option->pivot->price }}</p>
                      @php($total += $option->pivot->price)
                    </div>
                  </div>
                  <hr>
                @endforeach
                <div class="row">
                  <div class="col-md-6">
                    <h4>Options total: {{ $total }}</h4>
                  </div>
                </div>

But, that didn't work, I got an error:

Undefined variable: total

How can I do this?

This is something you should be doing in your controller or domain logic and passing it to the view, it shouldn't be the view's job to calculate information. — joepferguson

Define the variable first:

@php($total = 0);

You can also get sum of pivot column with:

$transaction->options()->sum('price')

Blade has a @php directive to execute a block of plain PHP within your template. Be aware that this may be a sign of bad design, and you should avoid put much logic inside your template. Ie:

@php
    $total = 0;
@endphp

@foreach ($items as $item)
<tr>
    <td>{{ $item->name }}</td>
    <td>{{ $item->code }}</td>
    <td>{{ $item->price }}</td>
</tr>

@php
    $total += $item->price;
@endphp

@endforeach

....

<p>Total {{ $total }}</p>

You can do that easily by saying

{{$transaction->options()->sum('price')}}

You can simply do the calculations in the blade template. This can be helpful for other users. Just do the calculation inside blade syntax {{ }} and use the display:none; css property. For example

<div style="display: none">
    {{ $total = 0 }}
</div>
@foreach($report as $device)
    <tr>
        <td>{{$device->id}}</td>
        <td>{{$device->price}}</td>
        <div style="display: none">{{$total += $device->price}}</div>
    </tr>
@endforeach
<tr>
    <th>Total Distance Travelled</th>
    <th>{{$total}}</th>
</tr>
