Showing a message if data is null laravel - php

Question

I want to show a message in my blade where if my address, name or number is null say this fields are empty please fill them up, if there are filled already, just don't display anything.
Currrently I did like this, but in the blade.php. Previously I had already asked something similar but this time I want to show a message. I tried following the question that I asked but for some reason it keep showing the message "please fill them up" even though my data contain values inside the database.
Redirect to page when value is null in another table laravel
Here is my code:
<?php
$additional_info = DB::table('additional_informations')
->whereNull('address')
->orWhereNull('name')
->orWhereNull('number')
->get();
if( $additional_info->count())
echo "test";
?>

Answer 1

For a route like this :
Route::get('/userAddInfo/{id}/AddInfo','VerificationController#AddInfo');
You can get the user id in the method as parameter then use it in the query like this :
public function AddInfo($id) {
$additional_info = DB::table('additional_informations')
->where('user_id', $id)
->where(function ($query) {
$query->whereNull('EC_address')
->orWhereNull('EC_name')
->orWhereNull('EC_number');
})
->get();
return view('AddVerificationInfo',compact('id','additional_info'));
}
And in the view :
#if($additional_info->count())
"Please fill this up"
#endif

Assuming you are working on the index.blade.php page here how it goes
InformationController - Controller
public function index($id) {
$additional_info = DB::table('additional_informations')
->whereNull('address')
->orWhereNull('name')
->orWhereNull('number')
->where('id', '=', $id)
->first();
return view('index', compact('id','additional_info '));
}
index.blade.php - View
<div>
#if(count($additional_info) > 0)
Here are the rows that has Null values: <br/>
Please go back and fill up the values of
#if($additional_info->EC_name == null)
EC_name
#endif
#if($additional_info->EC_relationship== null)
EC_relationship
#endif
#if($additional_info->EC_address== null)
EC_address
#endif
// and so on. There is a shorter way but I'm not in my laptop right now. But this should work fine
#else
{{ $id }} has no Null data found
#endif
</div>
Tell me if you need more help on this part. Cheers

/* In controller */
$additional_info = DB::table('additional_informations')
->whereNull('address')
->orWhereNull('name')
->orWhereNull('number')
->get()->toArray(); // to convert output into array
/* In view (blade template) */
#if(!empty($additional_info))
echo "<pre>";
print_r($additional_info);
#else
echo "No data found";
#endif

You should move your logic into a controller, then pass a variable like $noAdditionalInfo to the view
Then you can use blade tags:
#if($noAdditionalInfo)
<!-- html goes here -->
#endIf
