Laravel view foreach with two properties - php

Question

i need help with my foreach loop in view
Controller.php
$expenses = Expense::groupBy('category_id')->selectRaw('sum(amount) as sum, category_id')->pluck('sum','category_id');
$categories = Category::all();
return view('dashboard.index', compact('expenses','categories'));
index.php
<table class="table">
<thead>
<th>Category</th>
<th>Expenses</th>
</thead>
<tbody>
#foreach($categories as $category)
<tr>
<td>{{ $category->name }}</td>
#foreach($expenses as $expense)
<td>{{ $expense }}</td>
#endforeach
</tr>
#endforeach
</tbody>
</table>
I get the output like this.
enter image description here
It outputs the expense 2 times, is there a limiter for "foreach loop" or is there another way on doing this?

Answer 1

You need to add a condition for that $category->id is the same as category_id
#foreach($expenses as $key => $expense)
#if($key == $category->id)
<td>{{ $expense }}</td>
#endif
#endforeach
The right way to do it is by using join or relationship.
$expenses = Expense::join('categories','categories.category_id','expenses.category_id')->groupBy('expenses.category_id')->selectRaw('sum(expenses.amount) as sum, expenses.category_id','categories.name')->get();
<table class="table">
<thead>
<th>Category</th>
<th>Expenses</th>
</thead>
<tbody>
#foreach($expenses as $expense)
<th>{{ $expense->name }}</th>
<td>{{ $expense->sum }}</td>
#endforeach
</tbody>
</table>

Answer 2

You should limit the results in controller, but here's how you can accomplish this in a blade. Not pretty
#foreach ($element['subs'] as $item)
#if($loop->index < 10)
// Your code
#endif
#endforeach

Answer 3

You should compare category_id with category->id.
#foreach($categories as $category)
<tr>
<td>{{ $category->name }}</td>
#foreach($expenses as $expense)
#if($expense->category_id == $category->id )
<td>{{ $expense->sum }}</td>
#endif
#endforeach
</tr>
#endforeach
