Basic HTML Tutorial: Radio Buttons and Check Buttons in Forms

Radio button

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

Commonly used attributes

Name: The name of the element
Value: The value of the element, the value The data will be sent to the server.
Checked: Which item is selected by default. For example: checked = “checked”

Note: Only one of a set of radio buttons can be selected, but the value of the name must be consistent. For example: name = “sex”

The radio button user cannot enter the content himself, the user can only select, so it must refer to the default value value.

Check box

## Syntax format:

Common attributes

Note: The check box is also a set of options, so the value of the name must be consistent. In PHP, use an array to get the values of multiple names with the same name.

You can select multiple check boxes at the same time, or you can select none.

Let’s enrich our first example

        <meta http-equiv="Content-Type" content="text/html; charset=utf-8">
        <title>用户注册</title>
    </head>
    <body>
        <font size="5" color="red">欢迎注册php.cn</font>
        <form name="user" method="get" action="" >
            用户名：<input type="text" name="username"/>
            <br/>
            密码：<input type="password" name="userpwd"/>
            <br/>
            性别：<input type="radio" name="sex" value="男" checked=checked>男
            <input type="radio" name="sex" value="女">女
