Question

我希望能够从数据库中提取单选按钮值并能够对其进行编辑。我该怎么做呢？一切都插入正常，但是当我尝试搜索时，我得到一个错误＆＃34;注意：未定义索引：isVolunteer在C：\ xampp \ htdocs \ php_insert_update_delete_search.php第38行＆＃34;

我的代码：

<?php
 $host = "localhost";
 $user = "root";
 $password ="";
 $database = "2104299_test";

 $personID = "";
 $personFName = "";
 $personLName = "";
 $personAddress = "";
 $personContact = "";
 $personEmail = "";
 $personPassword = "";
 $isVolunteer = "";


 mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);

 // connect to mysql database
try{
$connect = mysqli_connect($host, $user, $password, $database);
} catch (mysqli_sql_exception $ex) {
echo 'Error';
}

// get values from the form
function getPosts()
{
$posts = array();
$posts[0] = $_POST['personID'];
$posts[1] = $_POST['personFName'];
$posts[2] = $_POST['personLName'];
$posts[3] = $_POST['personAddress'];
$posts[4] = $_POST['personContact'];
$posts[5] = $_POST['personEmail'];
$posts[6] = $_POST['personPassword'];
$posts[7] = $_POST['isVolunteer'];
return $posts;
}

// Search

if(isset($_POST['search']))
{
 $data = getPosts();

$search_Query = "SELECT * FROM tbl_people WHERE personID = $data[0]";

$search_Result = mysqli_query($connect, $search_Query);

if($search_Result)
{
    if(mysqli_num_rows($search_Result))
    {
        while($row = mysqli_fetch_array($search_Result))
        {
            $personID = $row['personID'];
            $personFName = $row['personFName'];
            $personLName = $row['personLName'];
            $personAddress = $row['personAddress'];
            $personContact = $row['personContact'];
            $personEmail = $row['personEmail'];
            $personPassword = $row['personPassword'];
            $isVolunteer = $row['isVolunteer'];
        }
    }else{
        echo 'No Data For This Id';
    }

}
}

    if($insert_Result)
    {
        if(mysqli_affected_rows($connect) > 0)
        {
            echo 'Data Inserted';
        }else{
            echo 'Data Not Inserted';
        }
    }
 } catch (Exception $ex) {
    echo 'Error Insert '.$ex->getMessage();
 }
}

// Delete
if(isset($_POST['delete']))
{
$data = getPosts();
$delete_Query = "DELETE FROM `tbl_people` WHERE `personID` = $data[0]";
try{
    $delete_Result = mysqli_query($connect, $delete_Query);

            echo 'Data Not Deleted';
        }
    }
 } catch (Exception $ex) {
    echo 'Error Delete '.$ex->getMessage();

}

// Edit
if(isset($_POST['update']))
