How to show children based on gender

Can you show an example of what dd($children) returns?

There is a where() collection method where you can get items from a collection that match.

Something like

<h2>Males</h2>
@php
    $males = $children->where('gender', 'man');
@endphp
@foreach($males as $male)
    {{ $male->name }}
@endforeach

<h2>Females</h2>
@php
    $females = $children->where('gender', 'vrouw');
@endphp
@foreach($females as $female)
    {{ $female->name }}
@endforeach 

But it depends on what your data looks like.

https://laravel.com/docs/5.6/collections#method-where

You can make it a bit more robust and show a message if there aren't any of one type or the other

<h2>Females</h2>
@php
    $females = $children->where('gender', 'vrouw');
@endphp

@if ($females->count())
    @foreach($females as $female)
        {{ $female->name }}
    @endforeach 
@else
     <div>Sorry, there are no female children.</div>
@endif

Personally, I'd do the $females = $children->where('gender', 'vrouw'); and same for males in the controller (after you've run the children query), and pass them to the view like you are with $children, just to keep the view cleaner.

Another option:

@foreach ($children->filter(function ($i) {return $i->gender === 'man';} as $child)

    <!--loop around children with gender = 'man'-->

@endforeach

@Cronix dd gets me: http://prntscr.com/j9l4jp but its not working.. I tried this:

        @php
              $males = $children->where('gender', 'man');
              @endphp

              @foreach($children as $male)

              {{ $child->name }}

              @endforeach 

But its not working either..

Actually, as Cronix suggested, ->where just seems the nicest. You could do:

@foreach ($children->where('gender', 'male') as $male)

    <!--loop around children with gender = 'man'-->

@endforeach

@devk getting an error -> http://prntscr.com/j9l7zm

Do the dd() again and click on one of the Child elements (the arrow in the graphic) to expand it so I can see the child's properties. I was just guessing the name based on what you stated. It might not be called "gender", or it might be in another object.

Whether the collection is empty, or the result is empty or not, this error doesn't happen because of the foreach. I think you have the error somewhere else.

@devk it would if the property isn't named gender

@Cronix http://prntscr.com/j9lbnx thanks

@Cronix If it's a model, it wouldn't. The property would simply return null and it would return false (so it wouldnt be in the returned result).

If it's a different object, the error should be something like Undefined property ..

Ok, so it's "Man" and not "man". Check what it is for female too and adjust.

$males = $children->where('gender', 'Man');

Also, your code is not the same as mine...

@php
$males = $children->where('gender', 'Man');
@endphp

@foreach($children as $male)  // should be foreach($males as $male)

    {{ $child->name }} // should be $male->name

@endforeach 

@cronix @devk yh it was Man with capital letters, sorry stupid of me :p But really thanks guys!!

No problem. If it's working now, please mark the issue as solved.

Out of pure curiosity I tried this in a sample project:

$videos = App\Video::get();
return $videos->where('nonexistant property', 'male');

The result was:

[]

$videos initially had 6 objects in it.

It didn't throw an error. The offset error has to have been somewhere else
