Laravel 5.1 in_array not working correctly?

Question

I am trying too check if a specific array contains a specific value with the in_array method. But for some reason it seems like it's not working.

@if (in_array(Auth::id(), $likedUsers))
        <p>yes</p>
@endif
    <?php echo Auth::id() ?>
    <?php dd($likedUsers) ?>

The results of my 2 dumps:

As you can see the array contains the value.

Answer 1

That is not how in_array() works. Your array contains objects and the objects are the things that contain the user id. in_array() will check the exact elements of the array it doesn't check the properties of the elements (the objects in this case).

It does something like this:

$isLikedUser = false;

foreach ($likedUsers as $likedUser) {
    if ($likedUser == Auth::id()) {
        $isLikedUser = true;
    }
}

But you need this:

$isLikedUser = false;

foreach ($likedUsers as $likedUser) {
    if ($likedUser->user_id == Auth::id()) {
        $isLikedUser = true;
    }
}

You should do this in your controller and then you can pass the result to your view like this:

$view = View::make('viewname')->with('isLikedUser', $isLikedUser);

Note that you don't have to give the same name to your view variable when you use the with() function, like: ->with('variableNameInView', $usedVariableValue);

Then your view will have a variable with the name of the first parameter that you can check:

@if ($isLikedUser)
    <p>yes</p>
@endif
<?php echo Auth::id() ?>
<?php dd($likedUsers) ?>
