Sample6_1.php 中建立Form：
上傳圖片函數 uploadimg： 複製代碼 代碼如下:function uploadimg(theform){
//提交Form
theform.submit();
//在showimg <div>中顯示上傳狀態
setStatus ("Loading...","showimg");
}
//上傳狀態函數
function setStatus (theStatus, theObj){
obj = document.getElementById(theObj);
if (obj){
obj.innerHTML = "<div class=\"bold\">" + theStatus + "</div>";
}
}
process_upload.php 提供檔案上傳功能： 複製代碼 代碼如下:<?php
//提供圖片類型校正
$allowedtypes = array("image/jpeg","image/pjpeg","image/png", "image/x-png","image/gif");
//檔案存放目錄
$savefolder = "images";
//如果有檔案上傳就開始幹活
if (isset ($_FILES['myfile'])){
//檢查上傳檔案是否符合$allowedtypes類型
if (in_array($_FILES['myfile']['type'],$allowedtypes)){
if ($_FILES['myfile']['error'] == 0){
$thefile = "$savefolder/".$_FILES['myfile']['name'];
//通過move_uploaded_file上傳檔案
if (!move_uploaded_file($_FILES['myfile']['tmp_name'], $thefile)){
echo "There was an error uploading the file.";
}
else{
?>

}
}
}

上面代碼最後部分的doneloading 函數就是用來顯示圖片及修改圖片尺寸大小。其中會用到thumb.php，它會在images目錄中產生出源圖片的大、中、小三個尺寸，有興趣可以研究一下。歡迎大家拍磚～
