如何使用带foreach循环的下拉菜单在数据库中插入数据

Question

here i am creating a attendance sheet that insert data into the database after clicking submit button. The insertion of the data is base on the 2 radio button which is absent/present, the problem is after clicking submit button the other component works accordingly except for the dropdown button, the dropdown button insert only a single string instead of the service time by the way i declare the service time in the database as varchar so i am confident that it's not the database that causes the error. maybe someone can help me any help is much appreciated. thank you in advance
enter code here

<?php
include("Sampledb.php");
include("Sample.php");
$flag=0;
if(isset($_POST['submit']))
{
    foreach($_POST['attendance_status'] as $id1=>$attendance_status)
        {
        $name=$_POST['name'][$id1];
        $id=$_POST['id'][$id1];
        $date=date("Y-m-d H:i:s");  
        $servicetime=$_POST['servicetime'][$id1];


        $result=mysqli_query($objconn,"insert into 
        attendrecord(id,name,attendance_status,attendance_date,servicetime)

        values('$id','$name','$attendance_status','$date','$servicetime')");            
            if($result)
            {
                $flag=1;
            }

Answer 1

Your service time is not an array as it keeps same for all record. So you need to change your PHP code as below:

$servicetime=$_POST['servicetime'];

Hope it helps you.

Answer 2

代替$_POST['servicetime'][$id]使用$_POST['servicetime']
