代碼很簡單，這裡我們就不多廢話了，直接奉上源碼
<?php
// 注冊表單的姓名
$name="";
$nameErr="";
if ($_SERVER["REQUEST_METHOD"]=="POST") {
if (empty($_POST['name'])) {
}else{
$name=$_POST['name'];
if (!preg_match("/^[a-zA-Z]*$/", $name)) {
$nameErr="只允許字母和空格";
}else{
echo '姓名'.$name;
}
}
// 文件上傳
if ((($_FILES["file"]["type"] == "image/gif")
|| ($_FILES["file"]["type"] == "image/jpeg")
|| ($_FILES["file"]["type"] == "image/pjpeg"))
&& ($_FILES["file"]["size"] < 2000000))
{
if ($_FILES["file"]["error"]>0) {
echo "錯誤：".$_FILES["file"]["error"]."<br/>";
}else{
echo "upload:".$_FILES["file"]["name"]."<br/>";
echo "type:".$_FILES["file"]["type"]."<br/>";
echo "size:".$_FILES["file"]["size"]."<br/>";
echo "stored in:".$_FILES["file"]["tmp_name"];
}
}else{
if (file_exists("weiwei/".$_FILES["file"]["name"])) {
echo $_FILES["file"]["name"]."上傳成功.";
}else{
move_uploaded_file($_FILES["file"]["tmp_name"],
"weiwei/" . $_FILES["file"]["name"]);
echo "Stored in: " . "weiwei/" . $_FILES["file"]["name"];
}
echo "上傳成功";
}
}
?>
