如何从数据库php中的动态下拉列表和文本框中保存多个值

  • php
  • html
  • mysql
  • javascript

I have a button that adds textboxes together with its food and animal value. However, I have a problem in saving it to the database. Is there a way that I can save all the add chosen animal name, food, birthday and given name. Let's say the user chose the dog, cat and monkey. How will I save all of the information together with the chosen dropdown class and animal into the database as it only saves the last added animal information and not all of the chosen options. Please I need help

Kindly go on full page to see how the code works and try to ignore first the error

<!DOCTYPE html>
<?php

$dbhost = 'localhost';
$dbuser = 'root';
$dbpass = 'my_password';
$db = 'my_db';

$dbconn = mysql_connect($dbhost, $dbuser, $dbpass);
mysql_select_db($db);


if (isset($_POST['submit']))
{
    $class        = $_POST['class'];
    $animal       = $_POST['animal'];
    $food         = $_POST['food'];
    $given_name   = $_POST['given_name'];
    $birthday     = $_POST['birthday'];

    $query = ("INSERT INTO my_table (class, animal, food, given_name, birthday) 
    VALUES ('$class', '$animal', '$food', '$given_name','$birthday')");
    
if(mysql_query($query))
 {
echo "<script>alert('INSERTED SUCCESSFULLY');</script>";
}
else
 {
 echo "<script>alert('FAILED TO INSERT');</script>";
 }

 }
