php简单文件图片批量上传程序代码
批量上传方法也很简单我们只要在给form时加个name=\"pictures[]\" 数组,然后再利用foreach ($_FILES[\"pictures\"][\"error\"] as $key => $error)对数组循环判断,再利用move_uploaded_file($tmp_name, $uploadfile); 实现文件上传就可以了.
html实例代码如下:
- <html>
- <head><title>upload picture more once</title></head>
- <body>
- <form action="" method="post" enctype="multipart/form-data">
- <p>Pictures:<br />
- <input type="file" name="pictures[]" /><br />
- <input type="file" name="pictures[]" /><br />
- <input type="file" name="pictures[]" /><br />
- <input type="submit" name="upload" value="Send" />
- </p>
- </form>
- </body>
- </html>
php处理实例代码如下:
- <?php
- if($_POST['upload']=='Send'){
- $dest_folder = "picture/";
- if(!file_exists($dest_folder)){
- mkdir($dest_folder);
- }
- foreach ($_FILES["pictures"]["error"] as $key => $error) {
- if ($error == UPLOAD_ERR_OK) {
- $tmp_name = $_FILES["pictures"]["tmp_name"][$key];
- $name = $_FILES["pictures"]["name"][$key];
- $uploadfile = $dest_folder.$name;
- move_uploaded_file($tmp_name, $uploadfile);
- }
- }
- }
- ?>
方法相当简单我们只是把单文件上传改成了多文件上传,其它只改了二个地方一个是表单名改成php数组形式一种是上传文件地方利用foreach来对数组遍历了.
