Question

我得到了这个Bootstrap Multiselect Dropdown文件，它在HTML中显示得很好。但我的问题是我如何捕获PHP中的选定选项

这是HTML

<html>
<head>
    <title>Multiselect</title>
    <link href="style.css" rel="stylesheet" type="text/css" />
    <link href="css/bootstrap.min.css" rel="stylesheet">
    <link rel="shortcut icon" href="favicon.ico">
    <script src="js/jquery.js"></script>
    <script src="js/bootstrap.min.js"></script>
    <script type="text/javascript" src="js/jquery.min.js"></script>
    <link href="css/bootstrap-multiselect.css"
        rel="stylesheet" type="text/css" />
    <script src="js/bootstrap-multiselect.js"
        type="text/javascript"></script>
    <script type="text/javascript">
        $(function () {
            $('#lstFruits').multiselect({
                includeSelectAllOption: true
            });
            $('#btnSelected').click(function () {
                var selected = $("#lstFruits option:selected");
                var message = "";
                selected.each(function () {
                    message += $(this).text() + " " + $(this).val() + "\n";
                });
                alert(message);
            });
        });
    </script>
</head>
<body>
    <tr>
        <td colspan="2" align="right">
            <form>
                <select id="lstFruits" multiple="multiple" name="fruits">
                    <option value="1">Lemon</option>
                    <option value="2">Apple</option>
                    <option value="3">Banana</option>
                    <option value="4">Guava</option>
                    <option value="5">Orange</option>
                </select>
                <button type="submit" class="btn btn-default" name="create_class">Create</button>
            </form>
        </td>
    </tr>
</body>

然后在PHP中捕获选项，我做了

if (array_key_exists(create_fruits, $_POST)) {
    echo $_POST['fruits'];
}

但什么都没发生。拜托，我该怎么办？
