如何在模式中使用id来在php中更新数据库

Question

所以我的目的是从数据库中获取ID并使id准备好用于模态。我知道我可以使用input type=hidden但我不确定它是否安全，因为在inspect元素中，用户可以编辑它。我也在考虑session，但我不知道我该怎么做。那么在提交后，我可以采取哪些方法使ID无法编辑？或者我怎么能把它放在数组中并匹配id？这是我用过的代码

class.names.php

public function getAllNames()
{
  $obj = new Db();
  $stmt = $obj->connect()->query("SELECT * FROM persons");
  while ($person = $stmt->fetch())
  {
    echo "<tr>";
    echo "<td>".$person['first_name']."</td>";
    echo "<td>".$person['last_name']."</td>";
    echo "<td><a id=\"".$person['person_id']."\"type=\"button\" data-target-toggle=\"modal\" data-target=\"#edit-name-modal\" class=\"btn btn-danger edit_data\" href=\"#\">Update</a></td>";
    echo "</tr>"; 
  }
}

names.js

$(document).on('click', '.edit_data', function(){  
 var person_id = $(this).attr("id");
 $.ajax({  
      url:"/data/updatename.php",
      method:"POST",
      data:{person_id:person_id},
      dataType:"json",  
      success:function(data){
        $('#first_name').val(data.first_name);
        $('#last_name').val(data.last_name);
        $('#person_id').val(data.person_id);
        $('#edit-name-modal').modal('show');         
      }  
 });  
});

updatename.php

<?php
include_once 'db.php';  
if(isset($_POST["person_id"]))  
{  
  $person_id = $_POST["person_id"]; 
  $object = new Dbc();
  $stmt = $object->connect()->prepare("SELECT * FROM persons WHERE person_id=?");
   $stmt->execute([$person_id]);  
  $profile_info = $stmt->fetch();
  echo json_encode($profile_info);    
}
?>

namelist.php
