My Answer:
It looks like there may be a couple of issues with your code.

Firstly, when using the `find` method in Laravel, you should pass the ID of the student as the first argument, not the entire student object. So your first line should be:

php
$res = student::find($student_id, ['typecertificate']);


Secondly, when using the `where` method in Laravel, you should pass the column name as the first argument and the value you are looking for as the second argument. So your second line should be:

php
$k = certificate::select('id-cer')->where('name-cer', $res->typecertificate)->get();


Make sure to replace `$student_id` with the actual ID of the student you are looking for, and make sure that the `typecertificate` column exists in the `student` table.

If you are still not getting any results, you may want to check the actual value of `$res->typecertificate` to make sure it is correct and matches the values in the `certificate` table.
