How do I get total in a foreach loop - laravel

Question

I have a div that displays items , quantities and total prices for each item using a foreach loop. I now want to get the total amount and dont seem to get it.
This is my blade file
<div class="order-summary">
<div class="order-col">
<div><strong>PRODUCT</strong></div>
<div><strong>TOTAL</strong></div>
</div>
<div class="order-products">
#if(session('cart'))
#foreach(session('cart') as $id => $details)
<?php
$total = 0;
$total += $details['price'] * $details['quantity'] ;
$total_amount += $details['price'] * $details['quantity'];
?>
<div class="order-col">
<div>
<h4 class="nomargin">{{$details['quantity'] }}x {{ $details['name'] }}</h4>
</div>
<div>KSh {{ $total }}</div>
</div>
#endforeach
#endif
</div>
<hr>
<div class="order-col">
<div>Shiping</div>
<div><strong>KSh 300</strong></div>
</div>
<hr>
<div class="order-col">
<div><strong>TOTAL</strong></div>
<?php $total_amount += $total?>
<div><strong class="order-total">KSh {{ $total_amount }} </strong></div>
</div>
</div>
I have also tried <div><strong class="order-total">KSh <?php echo $total_amount?> </strong></div> but still does not work.
I get an error of undefined variable total_amount. How do I go about it?

Answer 1

The variables $total and $total_amount must be outside of the foreach
here I have rewritten your code
<div class="order-summary">
<div class="order-col">
<div><strong>PRODUCT</strong></div>
<div><strong>TOTAL</strong></div>
</div>
#php $total = 0; $total_amount = 0; #endphp
<div class="order-products">
#if(session('cart'))
#foreach(session('cart') as $id => $details)
#php
$total += $details['price'] * $details['quantity'] ;
$total_amount += $details['price'] * $details['quantity'];
#endphp
<div class="order-col">
<div>
<h4 class="nomargin">{{$details['quantity'] }}x {{ $details['name'] }}</h4>
</div>
<div>KSh {{ $total }}</div>
</div>
#endforeach
#endif
</div>
<hr>
<div class="order-col">
<div>Shiping</div>
<div><strong>KSh 300</strong></div>
</div>
<hr>
<div class="order-col">
<div><strong>TOTAL</strong></div>
#php $total_amount += $total; #endphp
<div><strong class="order-total">KSh {{ $total_amount }} </strong></div>
</div>
</div>
