I have created a relationship between products and users using a foreign key called "previous_owner". I can see when I dump the value that I'm passing to the view that the data I'm after is available under:
$product->relations->product_owner->user->attributes->name
But how do I access it from within my view. I'm trying to loop through the products and then do something like:
{{ $product->product_owner->user->name }}
or
{{ $product->product_owner->name }}
But non of it works, keep getting:
" Trying to get property 'name' of non-object "
In your view code must be similar this
#foreach($products as $product)
{{ $product->product_owner->name }}
#endforeach
This code mean each product has product_owner. When one product does not have product_owner that case value of $product->product_owner is Null and then your code is null->name and you get error. For fix it you must be check relation is null or use ?? operator. Change your code to
#foreach($products as $product)
{{ $product->product_owner->name ?? ''}}
#endforeach
or
#foreach($products as $product)
#if($product->product_owner)
{{ $product->product_owner->name}}
#endif
#endforeach
If name is attribute and product_owner is relationship function then try the below:
{{ $product->product_owner()->name }}
Your product_owner isn't stdClass. It is array. So you can't access this key of this array with "->" operator. try
{{ $product->product_owner['name'] }}

What is the most effective way for returning data from two tables in on view?
Like an employee check the vehicle for each order.
Route::get('orderVehicle',"adminController#orderVehicle");
public function orderVehicle(Request $reques){
$orders = new Order;
$vehicles = new Vehicle; $orders->id; $vehicles->id; return view('adminVeiw.orderVehicle',compact('orders','vehicles')); }
#foreach($orders as $or) {{ $or->id }} #endforeach {{ $vehicles->id }}
And the error is
"Trying to get property 'id' of non-object (View:
/var/www/html/full-Restaurant-App-Using-Laravel/resources/views/adminVeiw/orderVehicle.blade.php)"
So any suggestions?
do this if you don't wanna change your code in controller
#foreach($orders as $or)
#if(!empty($or->id))
{{ $or->id }}
#endif
#endforeach
#if(!empty($vahicles->id))
{{ $vehicles->id }}
#endif
in this case you won't get error but i don't know how you wanna this works for you,
i hope it helps
public function orderVehicle()
{
$orders = Order::create();
$vehicles = Vehicle::create();
return view('adminVeiw.orderVehicle', compact('orders', 'vehicles'));
}
I have a Laravel model with many attributes. So, I need iterate over these attributes. How can I do this?
Something like this:
#foreach($model->attributes as $attribute)
// use $attribute
#endforeach
is it possible?
If you have an object, use getAttributes():
#foreach($model->getAttributes() as $key => $value)
// use $attribute
#endforeach
If these attributes were returned from a query, you can access the Model class directly:
E.g.
#foreach (User::all() as $user)
<p>This is user {{ $user->id }}</p>
#endforeach
or, you can access the model reference given to a template:
E.g.
#foreach ($user->permissions as $permission)
<p>This is an user permission {{ $permission->id }}</p>
#endforeach

I have Post model which has user function returning User model - creator of the post.
class Post extends Model
{
/**
* Get the user that owns the post.
*/
public function user()
{
return $this->belongsTo(User::class);
}
}
In blade view I achieved how to print author name
{{ $post->user->name or 'Anonymous' }}
Above code works, but it is very hmm sensitive?
For example, I tried change this code to:
{{ $post->user->name, 'Anonymous' }}
<?php $post->user->name or 'Anonymous' ?>
Results? Trying to get property of non-object error on line with this code.
Maybe I am skipping something simple but important. How to print URL or default value in blade view. Pseudo code what I mean:
{{ '' or 'Anonymous' }}
Try
{{ isset($post->user->name) ? '' : 'Anonymous' }}
If this doesn't work (I haven't check it) try something like this:
#if (isset($post->user->name))
#else
Anonymous
#endif
Actually the error is not because the code is sensitive, it is because you are actually trying to access non objects values.
To achieve what you are looking for:
{{ isset($post->user)?'' : 'Anonymous' }}
I use Laravel with foreach in a blade.php
{{ $users = App\User::where('user_id', $post->user_id)->get() }}
and I got the result of this which show on the page
[{"user_id":"123","email":"123#com","password":"1234","first_name":"Tony"}]
But I want to get "Tony" only, how can I call?
{{ ($users = App\User::where('user_id', $post->user_id)->first())->first_name }}
Or better in sense of performance, if you select posts with user:
{{ $post->user->first_name }}
But it is better to prepare necessary data in controller.
get() returns an array, you should use first()
{{ ($users = App\User::where('user_id', $post->user_id)->first())->first_name }}
Since you said you are using foreach in blade. Try something like this
#foreach($user as $u)
{{$u->first_name}}
#endforeach
This will give you first_name for all users
I need to find out unique value. So I tried bellow code. It is through undefined variable error.
Controller:
$employee = Employee::all();
Return view ('page', compact('employee'));
Page view:
$uniqueEmpLoc = $employee->unique('location')->values()->list('location')->toArray();
#Foreach($uniqueEmpLoc as $empLoc)
{{ $empLoc }}
//this is select box used for search
#endforeach
//Display Entire data
#foreach($employee as #employee)
//Display all value
#endforeach
But I got an uniqueEmpLoc is undefined error. I'm using LARAVEL 5.1. Please help me to solve this problem.
There are some errors in your code:
I don't think compact(employee) would work. Shouldn't that suppose to be compact('employee') ?
In Blade, there is no need of putting curly braces at all. Remove them.
Try out the following:
$employees = Employee::unique('locations')->values()->list('location')->toArray();
return view('page', compact('employees'));
And then in your view:
#foreach($employees as $employee)
{{ $employee }}
#endforeach
Use this query in controller
$employees = Employee::distinct()->list('location')->toArray();
return view('page', compact('employees'));
In view
#foreach($employees as $employee)
{{ $employee }}
#endforeach
I agree with the other answers here, this code should be in the controller. You shouldn't be doing logic in the views.
In the controller do:
$uniqueEmpLoc = $employee->unique('location')->values()->list('location')->toArray();
$employee = Employee::all();
Return view ('page', compact('employee', 'uniqueEmpLoc'));
The reason your code isn't working is the line that defines $uniqueEmpLoc is interpreted by blade as text, not code.
If you really want to do that in the view, you need to wrap it in #php tags.
#php
$uniqueEmpLoc = $employee->unique('location')->values()->list('location')->toArray();
#endphp
#Foreach($uniqueEmpLoc as $empLoc)
{{ $empLoc }}
//this is select box used for search
#endforeach
