mysqli_select_db（$ con，image）;
？>
INDEX.PHP
包括（ 'dbconfig.php'）;
if（isset（$ _ POST ['submit']））
{
$ name = $ _ POST ['name'];
$ img = $ _ FILES ['img'] ['name'];
$ result =插入图片值（'null'，'$ name'，'$ img'）;
if（mysqli_query（$ con，$ result））
{
move_uploaded_file（$ _ FILES ['image'] ['temp_name']，picture / $ img）;
echo< script>
alert（'image upload to folder'）
< / script>;
}

echo< script>
alert（'图片不上传到文件夹'）
< / script>;
}
