HTML basic tutorial form upload file field

Upload file field

##Syntax format: <input type = “file” attribute = “attribute” />

Common attributes

name: the name of the form element
value: the value of the form element, this value is actually uploaded file name. The value attribute is a read-only attribute. The content of this value can only come from manually selected uploaded files, and the user cannot specify a path. For security reasons, value is read-only.

Note: Now only the upload file box can be implemented, but the upload function cannot be truly implemented. The upload function is implemented with PHP.

Note:

When you need to upload a file, the form submission method can only be post method,
You must add enctype="multipart/form-data" to the form tag

Example:

<!DOCTYPE HTML>
<html>
    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=utf-8">
        <title>用户注册</title>

    <body>
