preg_match() expects parameter 2 to be string, object given - php

Question

i got this error when i'm trying to send multiple email, and i also want to pass a data to mail view.
here is my controller:
$get_no_inven = Permohonan::find($id_per)->no_inventaris;
$get_users = DB::table('users')->where('hak_akses','=','deputi')->get(['email']);
$recipients = [ $get_users ];
$subject = 'Testing email no 2';
$meta = 'meta';
foreach($recipients as $recipient) {
// here you declare variables accesable in view file
$dataToPassToEmailView = [];
// **key** of this table is variable **name in view**
$dataToPassToEmailView['no_inventaris'] = $get_no_inven;
Mail::send('mailkedua', $dataToPassToEmailView, function($message) use ($subject, $recipient, $meta) {
$message->to($recipient, 'Deputi Manager')->subject($subject);
$message->from('app.staging#nutrifood.co.id','Kalibrasi Online');
});
}
and here is my mail view:
<p>Dear Deputi Manager,</p>
<p>Berikut kami informasikan terdapat hasil kalibrasi terbaru alat dengan nomor inventaris {{$no_inventaris}}
Mohon bantuannya untuk melakukan approval, silahkan akses "Link CALON" http://baf-staging-x2:3030/lihat_permohonan_deputi/</p>
<p>Terima kasih,</p>
<p>CALON</p>
i don't understand where i'm doing wrong, thankyou!

Answer 1

You don't need to wrap the result of your query in an array. Also if you only want the email field from these records you could use pluck to get a list of them:
$recipients = DB::table('users')->where('hak_akses','=','deputi')->pluck('email');
foreach ($recipients as $recipient) {
...
}
This would make $recipient a string for the email address.
