我试图将变量传递到新页面，我在主题中创建了一个函数来获得结果。现在当我使用yelplist(); 在我的主题首页上，它会得到结果，当我点击链接时，它会按要求将图像和城市返回给我。

Questions:

<然而，我想知道我能做些什么让变量传递到自己的页面。例如：如果我单击该名称，一个新页面将显示该链接的图像和城市结果

Update 1

*我在使用$\\u会话方面取得了一些进展，现在我可以将变量传递到单个会话中。然而，当我点击这个链接时，它并没有更新单个链接中的变量。php文件，它只获取最后解析的链接信息，而不是我单击的链接信息。

还有，当我点击底部的链接，让它尝试转到单曲。php文件我找不到对象<a href=\'single.php?p=$pizza_url\'><img border=0 src=\'".$business->photo_url."\'></a> 我该怎么做才能让它转到单个页面并更新变量？

这是我在函数文件中的内容。

function yelplist(){

require_once (\'/lib/OAuth.php\'); 
require_once (\'yelp.php\'); 
require_once(ABSPATH.\'/wp-admin/includes/taxonomy.php\');

$yelpstring = file_get_contents(\'http://api.yelp.com/business_review_search?term=pizza&location=Los%20Angeles&ywsid=xxxxxxxxxxxxxxxxxxx\');
$obj = json_decode($yelpstring);

        foreach($obj->businesses as $business):
            $business->photo_url;
            $pizza_name = $business->url;
            $business->name;
            $business->phone;
            $city = $business->city;

            $url = \'\'.$business->url.\'\';
            $pizza = parse_url($url, PHP_URL_PATH);
            $pizza_url = trim(\'\'.$pizza.\'\',\'/biz\');
            $lower_case_city_url = $city;
            $lower_case_city_url = strtolower($lower_case_city_url);
            $city_url = str_replace(\' \',\'-\',$lower_case_city_url);

            if(isset($_SESSION[\'p\']) && $_SESSION[\'p\']==\'\'.$pizza_url.\'\') {

            $_SESSION[\'pizza_name\']= $business->name; 
            $_SESSION[\'pizza_city\']= $city = $business->city; 
            $_SESSION[\'pizza_phone\']= $business->phone;
            $_SESSION[\'pizza_photo\'] = $business->photo_url;

        }else{

        echo "<div><a href=\'?p=$pizza_url\'>$business->name</a></div>";
            }
        endforeach;
        }

这就是我在单曲中使用的内容。php文件来获取结果。

<?php session_start(); ?>
<?php echo $_SESSION[\'pizza_name\']; ?> </br>
<?php echo $_SESSION[\'pizza_phone\']; ?></br>
<?php echo $_SESSION[\'pizza_city\']; ?></br>
<?php echo "<img border=0 src=".$_SESSION[\'pizzaphoto\'].">"; ?>

谢谢
