Laravel Query Builder Return Results - laravel

Question

I have below Laravel Query, which runs very fine and returns the desired results.
$email = (Auth::user()->email);
$UerType = DB::table('tbl_schools')->where('email', $email)->pluck('type');
$parent_ids = DB::table('tbl_schools')->where('email', $email)->pluck('id');
// return $parent_ids;
if ($UerType == 'sub_admin') {
$children = DB::table('tbl_schools')->whereIn('id', $parent_ids)->get();
return $children;
} elseif ($UerType == 'school') {
$children = DB::table('tbl_schools')->where('email', $email)->get();
return $children;
} elseif ($UerType = 'admin') {
$children = DB::table('tbl_schools')->where('email', $email)->get();
return $children;
}
Out from Above is as expected
{
"id": 15,
"type": "sub_admin",
"parent_id": "12",
"username": "",
"access_role_type": "SCH2486518",
"school_code": "SCH2486518",
"school_name": "Test School",
"school_ad_name": "Support",
"address": "",
"email": "someemail#mail.com",
"mobile": "[phone]",
"school_logo": "",
"profile_image": "",
"status": "active",
"created": "2020-09-28 16:41:44",
"updated": "0000-00-00 00:00:00",
"token": ""
}
Now I need to Pick specific fields and save them to session for future use, but when I run the below code, strangely I still get the entire Query Result which is strange.
$email = (Auth::user()->email);
$UerType = DB::table('tbl_schools')->where('email', $email)->pluck('type');
$parent_ids = DB::table('tbl_schools')->where('email', $email)->pluck('id');
// return $parent_ids;
if ($UerType == 'sub_admin') {
$children = DB::table('tbl_schools')
->select('id','type','parent_id','school_name')
->whereIn('id', $parent_ids)
->get();
return $children;
} elseif ($UerType == 'school') {
$children = DB::table('tbl_schools')
->Select('id','type','parent_id','school_name')
->where('email', $email)
->get();
return $children;
} else {
$children = DB::table('tbl_schools')
->Select('id','type','parent_id','school_name')
->where('email', $email)
->get();
return $children;
}
I need help

First of all, you don't need to call the same query two times. Next, you are returning an array and compare it with a string. Do the following way. Hope this will give you the exact result.
$email = (Auth::user()->email);
$user = DB::table('tbl_schools')->where('email', $email)->first();
if ($uerType->type == 'sub_admin') {
$children = DB::table('tbl_schools')->whereIn('id', $user->id)->get();
return $children;
} elseif ($user->type == 'school') {
$children = DB::table('tbl_schools')->where('email', $email)->get();
return $children;
} elseif ($user->type = 'admin') {
$children = DB::table('tbl_schools')->where('email', $email)->get();
return $children;
}
