Question

这是将复选框值提交到validatepreferences.php。

的表单

<form action="validatepreferences.php" method="post">    <fieldset>
        <legend>
            Widgets
        </legend>
        <input type="checkbox" name="checkwidget[]" value="weather"> Hamilton Weather<br>
        <input type="checkbox" name="checkwidget[]" value="nzherald"> NZ Herald
    </fieldset>
    <input type="submit" value="Save Changes">

这是validatepreferences.php文件，我在其中设置了cookie值。（这段代码一切正常，但我还没有弄清楚如何获得两个cookie值的数组）

<?php
if (isset($_POST['checkwidget'])) {
    $checkwidget = $_POST['checkwidget'];
    if ($checkwidget == "weather" || $checkwidget == "nzherald") {
        setcookie("widget", $checkwidget, time() + 31536000 , "/");
    }
}
header('Location: homepage.php');
?>

这是我用来为变量赋值以隐藏和显示小部件的PHP代码

<?php
$widgetchoice = "";
if (!isset($_COOKIE['widget'])) {
    $widgetchoice = "weather" && "nzherald";
} else {
    $widgetchoice = $_COOKIE['widget'];
}
?>

这是这个代码的问题我无法根据首选项中设置的cookie来设置和消失这些小部件（帮助我卡住）

<div id="columnright">
    <!-- BEGIN NZHERALD PREGENERATED WIDGET BLOCK -->

    <script type="text/javascript" src="http://www.nzherald.co.nz/apps/js/ReaderWidget/ReaderWidget.js"></script>
    <script type="text/javascript" src="http://www.nzherald.co.nz/apps/js/JsonFeeder/JsonFeeder.js"></script>
    <script type="text/javascript">
    if (<?php echo $widgetchoice?> == 'nzherald'){
        var feedsource = new JsonFeeder("http://www.nzherald.co.nz/json/rss/", {
            "feedLink" : "http://www.nzherald.co.nz/",
            "name" : "NZ Herald Up To The Minute"
        });
        var feedreader = new ReaderWidget("readerDiv", feedsource, 6);
        window.onload = function() {
            feedreader.run();
        }
    </script>
    <br>
    <div align="center">
        <!-Weather in Hamilton, New Zealand on your site - HTML code - weatherforecastmap.com -->
        <script>
        if (<?php echo $widgetchoice?> == 'weather'){
            < src="http://www.weatherforecastmap.com/weather2.php?zona=new-zealand_hamilton">
        </script>
    </div>

如何使用php cookies和javascript添加和删除小部件？
