Question

我还是个新手，我真的很难过。当选择第一个复选框时，如何将嵌入的YouTube视频回显到页面？请帮忙。感谢。

<form action="" method="post">
  <label><input type="checkbox" name="check_list[]" value="<?php echo "<iframe width=\"640\" height=\"360\" src=\"http://www.youtube.com/embed/TnxUOdAhAdk\" frameborder=\"0\" allowfullscreen></iframe>"; ?>">Video1</label>
  <label><input type="checkbox" name="check_list[]" value="value 2">Video2</label>
  <label><input type="checkbox" name="check_list[]" value="value 3">Video3</label>
  <input type="submit" />
</form>


<?php
if(!empty($_POST['check_list'])) {
    foreach($_POST['check_list'] as $check) {
        echo $check;
    }
}
?>

我建议你使用javascript / jquery而不是php，因为你已经知道你的youtube链接。 This link will give you more info about this

无论如何这里有一个可以帮助你的PHP代码：

<html>
<head>
</head>
<body>
    <form action='index.php' method='post'>
        <input type='checkbox' name='video1' value='true'/>Show Video1
        <br/>
        <input type='checkbox' name='video2' value='true'/>Show Video2
        <br/>
        <input type='checkbox' name='video3' value='true'/>Show Video3
        <br/>
        <input type='submit' value='Show Videos'/>
    </form>

    <?php
    if (isset($_POST['video1'])) {
        echo "<iframe width=\"640\" height=\"360\" src=\"http://www.youtube.com/embed/TnxUOdAhAdk\" frameborder=\"0\" allowfullscreen></iframe>";
        echo "<br/>";
        echo "<br/>";
    }
    if (isset($_POST['video2'])) {
        echo "<iframe width=\"640\" height=\"360\" src=\"http://www.youtube.com/embed/2mKxsC2oi5s\" frameborder=\"0\" allowfullscreen></iframe>";
        echo "<br/>";
        echo "<br/>";
    }
    if (isset($_POST['video3'])) {
        echo "<iframe width=\"640\" height=\"360\" src=\"http://www.youtube.com/embed/tC2fjzWIM-Y\" frameborder=\"0\" allowfullscreen></iframe>";
        echo "<br/>";
        echo "<br/>";
    }
    ?>
</body>
</html>

echo iframe里面的值
