The 0 field is required. Laravel 5.5 Validation error - php

Question

Am having a "The 0 field is required." error while trying save data into database when I have no field called 0. without validation from the Controller, the data saves but if I validate even just one field out of the six field I want to validate, I still get the error. How do I solve the issue. Please help out here is my view

{{ csrf_field() }}

<select id="ddlGenge" class="form-control" name="tenant_id" required="">
#foreach($tenants as $tenant)

</div>
</div>
<button type="submit" class="btn btn-outline btn-primary pull-right">Submit</button>

</form>
and my controller
public function store(Request $request)
{
//validation
$this->validate($request, array([
'tenant_id' => 'required',
'asset_id' => 'required',
'description' => 'required',
'address' => 'required',
'price' => 'required',
'occupation_date' => 'required',
]));
//create and save new data
$tenantProperty = New TenantProperty();
$tenantProperty->tenant_id = $request->tenant_id;
$tenantProperty->asset_id = $request->asset_id;
$tenantProperty->description = $request->description;
$tenantProperty->address = $request->address;
$tenantProperty->price = $request->price;
$tenantProperty->occupation_date = $request->occupation_date;
$tenantProperty->save();
//redirect
return redirect('agent/tenantProperty_list');
}
with the route as follows
Route::get('add_tenantProperty', 'TenantPropertyController#create')->name('/add_tenantProperty');
Route::post('add_tenantProperty', 'TenantPropertyController#store');

Answer 1

When you just write $request, it passes the entire request object but the validate function expect both the arguments to be arrays.
So make a little change and you will be good to go:
$this->validate($request, array( // Removed `[]` from the array.
'tenant_id' => 'required',
'asset_id' => 'required',
'description' => 'required',
'address' => 'required',
'price' => 'required',
'occupation_date' => 'required',
));

Answer 2

The above answer is correct, this is another way to solve the validation problem on laravel 5.5 I asked
$validation = validator::make($request->all(), [
'tenant_id' => 'required',
'asset_id' => 'required',
'description' => 'required',
'address' => 'required',
'price' => 'required',
'occupation_date' => 'required',
]);

Answer 3

$request->validate([
'0'=>'',
'tenant_id' => 'required',
'asset_id' => 'required',
'description' => 'required',
'address' => 'required',
'price' => 'required',
'occupation_date' => 'required',]);
