Use variable outside foreach laravel - php

Question

I have a problem with Laravel. So what am I trying to do? I'm trying to get the location from all my examples. This actually works, so as you can see I get the id of all the examples and find the locations of it from another table in my project. The var_dump in the foreach gives what I need. But I need this data outside the foreach, I need to send it to my view afterwards. But the second var_dump, the one outside the foreach only gives the location of the first id.
So my question: is there a way to get the full $locations outside the foreach.
$ids= DB::table('example')
->select('id')
->get();
foreach($ids as $id)
{
$locations = example::find($id->id)->locations()->get();
var_dump($locations);
}
var_dump($locations);
This is my view:
#foreach($examples as $example)
<h1>{{$example->name}}</h1>
#foreach($locations as $location)
{{$location}}
#endforeach
#endforeach
I see al the locations from al the $examples in every $example if I print it like this, I hope you understand my question.

Answer 1

Try this:
// Define locations array
$locations = [];
// Then do the following for each example:
// Define the array for locations of each example outside of the loop
$locations[$example->name] = [];
foreach ($ids as $id) {
// Add each location to the $locations array
$locations[$example->name][] = example::find($id->id)->locations()->get();
}
Or if you want to get a little bit more fancy, you can use array_map instead of foreach:
$locations[$example->name] = array_map(function ($id) {
return example::find($id->id)->locations()->get();
}, $ids);
Then in the view, you simply take out the locations from the right key for each example:
#foreach ($examples as $example)
<h1>{{ $example->name }}</h1>
#foreach ($locations[$example->name] as $location)
{{ $location }}
#endforeach
#endforeach
You don't have to use the $example->name as the key, just make sure it's unique for each example you want to fetch locations for.
I hope this helps.

There is no need to build the $locations array. You can use the relationship in the view just fine.
In your controller:
// whatever your logic is to get the examples
$examples = example::with('locations')->get();
In your view:
#foreach($examples as $example)
<h1>{{$example->name}}</h1>
#foreach($example->locations as $location)
{{$location}}
#endforeach
#endforeach
