I was trying to fit an existing PHP project into my Laravel project. I’ve tried so that I can gather knowledge how to fit a project into the Framework. Now, whenever I wanted to update or delete specific student by their respective id, it always update or delete the latest entry. Why does it happen and how can I solve this?

This is my routes/web.php

Route::post('admin/update-student/{id}',[StudentListController::class,'update'])->name('update-student');

This is my StudentListController@update

 public function update(Request $request, int $id)
    {
        
        $student = StudentList::find($id);
        
        $student->student_name = $request->student_name;
        $student->course_section = $request->course_section;
        
        $student->save();

        return redirect()->route('student-list')->with('success', 'Student updated successfully!');
    }

This is my views

<div class="modal fade" id="updateStudentModal" data-backdrop="static" data-keyboard="false" tabindex="-1"
        aria-labelledby="updateStudent" aria-hidden="true">
 <div class="modal-body">
                    <form action="{{ route('update-student', $student->id) }}" method="POST">
                        @csrf
                        <input type="hidden" class="form-control" id="updateStudentId" name="tbl_student_id">
                        <div class="form-group">
                            <label for="updateStudentName">Full Name:</label>
                            <input type="text" class="form-control" id="updateStudentName" name="student_name" value="{{ $student->student_name }}">
                        </div>                       
                        <div class="form-group">
                            <label for="updateStudentCourse">Course and Section:</label>
                            <input type="text" class="form-control" id="updateStudentCourse" name="course_section" value="{{ $student->course_section}}">
                        </div>
                        <div class="modal-footer">
                            <button type="button" class="btn btn-secondary" data-dismiss="modal">Close</button>
                            <button type="submit" class="btn btn-dark">Update</button>
                        </div>
                    </form>
                </div>
</div>

Here is some JS for Update modal for update button

 function updateStudent(id) {
            $("#updateStudentModal").modal("show");

            let updateStudentId = $("#studentID-" + id).text();
            let updateStudentName = $("#studentName-" + id).text();            
            let updateStudentCourse = $("#studentCourse-" + id).text();

            $("#updateStudentId").val(updateStudentId);
            $("#updateStudentName").val(updateStudentName);            
            $("#updateStudentCourse").val(updateStudentCourse);
        }
