laravel foreach loop in controller - php

Question

i have a problem about looping data in controller (laravel 4). my code is like this:
$owner = Input::get('owner');
$count = Input::get('count');
$product = Product::whereOwnerAndStatus($owner, 0)->take($count)->get();
when i want to use foreach to loop for $product result with code like this:
foreach ($product->sku as $sku) {
// Code Here
}
the result is returning error
Undefined property: Illuminate\Database\Eloquent\Collection::$sku
so, i try to improvise a little with this code:
foreach ($product as $items) {
foreach ($items->sku as $sku) {
// Code Here
}
}
the code returning error like this:
Invalid argument supplied for foreach()
is there someone who could help me solve this?

Answer 1

This will throw an error:
foreach ($product->sku as $sku){
// Code Here
}
because you cannot loop a model with a specific column ($product->sku) from the table.
So, you must loop on the whole model:
foreach ($product as $p) {
// code
}
Inside the loop you can retrieve whatever column you want just adding ->[column_name]
foreach ($product as $p) {
echo $p->sku;
}

Answer 2

Actually your $product has no data because the Eloquent model returns NULL. It's probably because you have used whereOwnerAndStatus which seems wrong and if there were data in $product then it would not work in your first example because get() returns a collection of multiple models but that is not the case. The second example throws error because foreach didn't get any data. So I think it should be something like this:
$owner = Input::get('owner');
$count = Input::get('count');
$products = Product::whereOwner($owner, 0)->take($count)->get();
Further you may also make sure if $products has data:
if($product) {
return View:make('viewname')->with('products', $products);
}
Then in the view:
foreach ($products as $product) {
// If Product has sku (collection object, probably related models)
foreach ($product->sku as $sku) {
// Code Here
}
}

Answer 3

The view (blade template): Inside the loop you can retrieve whatever column you looking for
#foreach ($products as $product)
{{$product->sku}}
#endforeach

Answer 4

Is sku just a property of the Product model? If so:
$products = Product::whereOwnerAndStatus($owner, 0)->take($count)->get();
foreach ($products as $product ) {
// Access $product->sku here...
}
Or is sku a relationship to another model? If that is the case, then, as long as your relationship is setup properly, you code should work.

Answer 5

$allData = Model::where('status', 1)->get();
foreach ($allData as $data){
$data->status = 0;
$data->update();
}
Here every $data is single data and $allData contains full collection.

Answer 6

using foreach on table
for me
#foreach($products as $data)
<tr>
<td>{{$data->id}}</td>
<td>{{$data->name}}</td>
<td>{{$data->price}}</td>
</tr>
#endforeach
