Question

我要上传图片

我想用图像向数据库添加一些数据。但图片显示未定义索引

<?php

require('include/database.php');

$dir_student_photos = 'images/';

$course_name = $_POST['course_name'];
$fees = $_POST['fees'];
$old_fee = $_POST['old_fee'];
$duration = $_POST['duration'];

$photo_name = $_FILES['photo']['name'];
$photo_tmp_name = $_FILES['photo']['tmp_name'];
$photo_size = $_FILES['photo']['size'] / 1024;
$photo_allowed_ext = array('.jpg', '.jpeg', '.png');

$photo_extension = strrchr($photo_name, '.');
$photo_extesion = strtolower($photo_extension);

if(!in_array($photo_extension , $photo_allowed_ext))
    {
        die('Error: invalid image file');
    }


if($photo_size > 1024)
    {
        die('Error: File size is large');
    }

$upload = move_uploaded_file($photo_tmp_name, $dir_student_photos . $photo_name);

$sql = "INSERT INTO course

        SET

        course_name = '$course_name',
        fees = '$fees',
        old_fee = '$old_fee',
        duration = '$duration'
        photo= '$photo_name'
        ";

$query = mysqli_query($connection, $sql);


if(!$query)
{

    echo "Error: Cannot add to the database";

}
else{

    echo "Success: Course registered";

}
}
?>
