Getting error message from Laravel's foreach loop:
Invalid argument supplied for foreach()
My foreach loop is :
@foreach ($task as $tasks)
<td>{{$tasks->name}}</td>
@endforeach
My controller is:
public function show($id){
$task = Task::find($id);
return view('tasks.show')->withTask($task);
;
}
You are giving a wrong data type to the foreach loop.
A foreach requires an array or a Collection.
The statement
$task = Task::find($id);
will give you a Task model (not a Collection).
Hence you cannot iterate over it.
Also, since you are trying to display the Task resource (assuming this as you are calling the controller's show() function), you don't need to iterate over the model - as you will be displaying a single entity's attributes.
Just do this
Controller:
public function show($id){
$task = Task::find($id);
return view('tasks.show', compact('task'));
}
In the view:
Name: {{ $task->name }}
// other attributes here
I Never seen to set variable like you, try this
return view('tasks.show')->with('task', $task);
Reverse the foreach variables
@foreach ($tasks as $task)
<td> {{ $task->name }} </td>
@endforeach
You should write this. This will solve your problem
Your Controller
public function show($id){
$task = Task::findOrFail($id);
return view('tasks.show', compact('task'));
}
As it gets only one value so no need to use foreach. You should write this
<td>{{$tasks->name}}</td>
The findOrFail method return only one value. So No need to loop it. Hopefully this will solve your problem.
$tasktraversable?dd($task)before the foreach inside blade.$task = Task::find($id);. It just returns the matchingTaskobject
