将单选按钮中的数据存储在MySQL数据库中

Question

I have a form that requires an input from a user such as name, surname, telephone #, address, etc., and it contains Yes/No questions. For Yes/No questions I use radio buttons, for example: Is red your favorite colour? Yes No. A user has to check one. That form is inside my .php file, I also have another .php file that is connected with the form and should store data inside the database in MySQl. My question is am I storing radio buttons correctly and inside my database should my radio buttons be boolean?

A piece of my form that contains radio buttons:

<div class="control-group questions">
<div class="field-control">
<p>This is a Yes/No question</p>
<div class="input-wrapper">
<div class="answer"><input class="btn-checkbox" type="radio" name="groupone" value="yes" /><label>Yes</label></div>
<input class="btn-checkbox" type="radio" name="groupone" value="no" /><label>No</label><br />
</div>
</div>
</div>
<div class="control-group questions">
<div class="field-control">
<p>This is a Yes/No question</p>
<div class="input-wrapper">
<div class="answer"><input class="btn-checkbox" type="radio" name="grouptwo" value="yes" /> <label>Yes</label></div>
<input class="btn-checkbox" type="radio" name="grouptwo" value="no" /><label>No</label><br /
</div>
</div>
</div>

MySQL:

$value = @$_POST ['groupone'];
$sql = "INSERT INTO checkout (groupone) VALUES ('$value')";

if (!mysqli_query($connection, $sql)){
    die('Error: ' . mysqli_connect_error($connection));
}

$value = @$_POST ['grouptwo'];
$sql = "INSERT INTO checkout (grouptwo) VALUES ('$value')";

if (!mysqli_query($connection, $sql)){
    die('Error: ' . mysqli_connect_error($connection));
}

如果要将布尔值存储在数据库中，请使用此代码

$value = @($_POST ['groupone'] == 'yes') ? true : false;
