Laravel 5.2 foreach associative array in key return index

Question

I have this piece oh code:

<?php
    
$levels = array( "0" => "Super User", "1" => "Administrator", "10" => "10", "20" => 20, "30" => "30", "40" => "40", "50" => "50", "99" => "99 News homepage" );

?>

<select name="level" id="modify_modal_level">
    @foreach( $levels as $key => $val )
            <option value="{{ $key }}" <?php echo $selected==$key ? 'selected="selected"': ""?>>{{ $val }}</option>
    @endforeach
</select>

Why the $key inside foreach return the INDEX of array? example:

@foreach( $levels as $key => $val )
   {{ $key }},
@endforeach

prints out: 1,2,3,4,5,6,7,8,

instead of: '0','1','10','20','30','40','50','99'

but the foreach loop in the $key variable MUST return the key value of the associative array, not the key index!

my select results:

<select name="level" id="modify_modal_level">
<option value="1">Super User</option>
<option value="2">Administrator</option>
<option value="3">10</option>
...
<option value="8">99 News homepage</option>
</select>

instead of:

<select name="level" id="modify_modal_level">
<option value="0">Super User</option>
<option value="1">Administrator</option>
<option value="10">10</option>
...
<option value="99">99 News homepage</option>
</select>

Thanks!!

It's difficult to understand what you are getting and what you are wanting. Can you clarify? — Patrick Stephan

I just executed your provided code and received the 0, 1, 10 index keys as expected. Are you sure your $levels variable contains the data you think it contains? — Logan Bailey

If you are wanting what you have under "example" then simply remove the keys in your $levels array. — Patrick Stephan

@PatrickStephan it looks like they want what's under "instead of"...I think. However, that's what they would get with the blade provided...so now I'm not so sure. — camelCase

Your code will work as you have it now; are you certain that $levels is correctly generated as you're showing it here?

Controller

$levels = [
    0 => "Super User",
    1 => "Administrator",
    10 => 10,
    20 => 20,
    30 => 30,
    40 => 40,
    50 => 50,
    99 => "99 News homepage",
];

return view('yourview', [
    'levels' => $levels,
    'selected' => '99'
]);

yourview.blade.php

<select name="level" id="modify_modal_level">
    @foreach ($levels as $key => $value)
        <option value="{{ $key }}" @if ($selected == $key) selected @endif>{{ $value }}</option>
    @endforeach
    {{-- $key will be 0, 1, 10, 20, 30, 40, 50, 99 --}}
    {{-- $value will be "Super User", "Administrator", 10, 20, 30, 40, 50, "99 News homepage" --}}
</select>

Note that I also updated to use @if Blade syntax since it's much cleaner and easier to read.

When accessing the view, I get this returned:

the code is all in a include file, loaded with @include(..). The array is initialized inside the include!!

That should not make a difference. I just used controller because it's how I have my layout defined. If you're loading $levels as the array is shown above, then it should still work. Have you tried var_dump() or dd() on $levels to confirm the index's are correct?

solved!! i have used "normal" php foreach <?php foreach() ?> and all works fine!!
