Laravel Blade access object property using variable

Question

In a blade template y controller passes a object which has few values in properties as bellow

value_L1 = "Hello"
value_L2 = "Stack"
value_L3 = "OverFlow"

I want to use a for loop to display these values but the statement in loop returns null, how can I do such a thing in blade?

@for ($count = 1; $count < 3; $count++)
    {{ $object->{'value_L.$count'} }}
@endfor

I am able to access these properties as following

{{ $object->value_L1 }}
{{ $object->value_L2 }}

Thanks,

K

Single quotes will treat strings as literals, meaning your `$count` will be treated as a string `$count` not as the variable `$count`.

I saw this to access a property using a variable `$object->{'$var'}` where `$var="value_L1"` that worked. — karmendra, Oct 16 '15 at 15:30

How about

@for ($count = 1; $count < 3; $count++)
    {{ object_get($object, "value_L{$count}" ) }}
@endfor

Excellent! Can you please mark it as correct answer? – Glad To Help Oct 16 '15 at 15:31
Yes I will, I am testing his edit, and also when i try `@if (isset(object_get($object, "value_L{$count}" )))` it gives syntax error – karmendra Oct 16 '15 at 15:36
do you have `@endif`? – Glad To Help Oct 16 '15 at 15:39
When I search on object_get I see no info on php.net or laravel documentation. Does it return false or null if property it is trying to access isn't available? – karmendra Oct 16 '15 at 15:45
Yes I have `@endif`, in fact I have a `@else` followed by `@endif` – karmendra Oct 16 '15 at 15:46
It is a laravel function, similar to `array_get()`, and also there is a third function called `data_get()` that works for both arrays and objects. You can take a look at it here http://laravel.com/docs/5.1/helpers#method-array-get – Glad To Help Oct 16 '15 at 15:48
and yes it will return false if you try to access a property that is not available. – Glad To Help Oct 16 '15 at 15:50
Right, I checked it returns null if property doesn't exist so now I can use it in if without isset. Thanks again. – karmendra Oct 16 '15 at 15:51
