首先向大家介绍一下html5中file的multiple属性
定义和用法
multiple 属性规定输入字段可选择多个值。如果使用该属性,则字段可接受多个值。
实例:
- <form action="demo_form.asp" method="get">
- Select images: <input type="file" name="img" multiple="multiple" />
- <input type="submit" />
- </form>
上面实例中的input file 可接受多个文件上传字段。
了解了html5中file的multiple属性,下面我们开始讲解使用html5实现多文件上传。
实例代码:
html:
- <!DOCTYPE html>
- <html>
- <head>
- <meta charset="UTF-8">
- </head>
- <body>
- <form action="my_parser.php" method="post" enctype="multipart/form-data">
- <p><input name="upload[]" type="file" multiple="multiple" /></p>
- <input type="submit" value="Upload all files">
- </form>
- </body>
- </html>
php代码:
- for($i=0; $i<count($_FILES['upload']['name']); $i++) {
- //Get the temp file path
- $tmpFilePath = $_FILES['upload']['tmp_name'][$i];
- //Make sure we have a filepath
- if ($tmpFilePath != ""){
- //Setup our new file path
- $newFilePath = "./uploadFiles/" . $_FILES['upload']['name'][$i];
- //Upload the file into the temp dir
- if(move_uploaded_file($tmpFilePath, $newFilePath)) {
- //Handle other code here
- }
- }
- }
