In this article, we will learn how to allow multiple files uploads in HTML forms.
我们使用多个属性，以允许在HTML表单中进行多个文件上传。多个属性适用于电子邮件和文件输入类型。
If you want to allow a user to upload the file to your website, you need to use a file upload box, also known as a file, select box. This is created using the element and the type of attribute is set to file.
以下是在HTML表单中选择多个文件上传的语法。
<input type="file" name="name" multiple>
以下是HTML表单中选择多个文件上传的示例程序。
<!DOCTYPE html>
<html>
<head>
<title>Upload multiple files</title>
<meta charset="UTF-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
</head>
<body>
<form>
<input type="file" name="name" multiple><br><br>
<br>
<input type="submit" value="Submit">
</form>
</body>
</html>
以下是上述示例程序的输出，其中在输入字段中未选择任何文件。
