Limit foreach query

  • 772

How can I limit a @foreach ? I use a foreach to show the data of a related table and I would like to limit the results of that foreach I try to use this but it gives me an error

{{$count = 0;}}  @foreach($product->post as $produc)  {{if($count == 4) break; }}

///contenido

{{$count++;}}

any ideas ?

  1. Best Answer

    You can achieve this with @break :

    @php
$count = 0;
@endphp

@foreach($product->post as $produc)

    @break($count == 4)

    ///contenido

    @php
    $count++;
    @endphp

@endforeach

    But as an alternative you could use:

    @foreach($product->post as $count => $produc)

    @break($count == 4)

    ///contenido

@endforeach

  2. If $countit is always a number, I would propose that in the controller you divide that array of results into arrays of that size. Then you would pass the first array to the template.

    example:

    $count = 4;
$resultados = ['a', 'b, 'c', 'd', 'e','f,','g','h'];

$listas = array_chunk ($resultados, $count, true);

    Now, in $list you have an array of arrays. The first array has the first 4 elements, the second the second 4, and so on.

    $productos = $listas[0]; // ahora tienes los 4 primeros en $productos.

    send $products to your template and iterate through the foreach.
