从复选框表单中创建数组

Question

我和我的朋友正在建立一个根据您的兴趣编辑新闻故事的网站.有没有简单的方法来获取复选框数据并从所选复选框中创建一个数组？这是我们的表格

<form action="signup.php" method="POST">
    Name: <input type="text" name="name" /> <br />
    Username: <input type="text" name="username"> <br />
    Password: <input type="password" name="pwd" /> <br />
    Email: <input type="text" name="email" /> <br />

    <p>By filling out this we will be able to find news articles that will interest you</p>        <br />
    Politics<input type="checkbox" name="interest[]" value="Politics" /> <br />
    Entertainment<input type="checkbox" name="interest[]" value="Entertainment" /> <br />
    Tech <input type="checkbox" name="interest[]" value="Tech" /> <br />
    Health<input type="checkbox" name="interest[]" value="Health" /> <br />
    Living<input type="checkbox" name="interest[]" value="Living" /> <br />
    Travel <input type="checkbox" name="interest[]" value="Travel" /> <br />
    World<input type="checkbox" name="interest[]" value="World" /> <br />
    Leisure<input type="checkbox" name="interest[]" value="Leisure" /> <br />
    Finance<input type="checkbox" name="interest[]" value="Finance" /> <br />
    Celebrity Gossip<input type="checkbox" name="interest[]" value="Gossip" /> <br />
    Movies<input type="checkbox" name="interest[]" value="Movies" /> <br />
    Sports<input type="checkbox" name="interest[]" value="Sports" /> <br />

    <input type="submit" value="Submit">
</form>

我们如何使用这些数据制作一个php数组？

Answer 1

HTML标记:

<form method="get">
    <input type="checkbox" name="options[]" value="Politics"/> Politics<br/>
    <input type="checkbox" name="options[]" value="Movies"/> Movies<br/>
    <input type="checkbox" name="options[]" value="World "/> World<br/>
    <input type="submit" value="Go!" />
</form>

并在PHP代码中:

$checked = $_GET['options'];
for($i=0; $i < count($checked); $i++){
    echo "Selected " . $checked[$i] . "<br/>";
}

Answer 2

用这个:

<input type="checkbox" name="mydata[checkbox1]"> Option 1 (politics etc)
<input type="checkbox" name="mydata[checkbox2]"> Option 2
<input type="checkbox" name="mydata[checkbox3]"> Option 3

然后访问$ _POST ["mydata"]作为数组
