我正在为电视wordpress网站(www.canal-en-vivo.com)工作几个php函数,根据频道提要是否有效,将帖子(即频道)的状态从已发布更改为草稿或不。我把以下两个函数放在一起,但它们似乎不起作用。您是否可以看一下通用代码结构,如果您看到结构奇怪的东西,请告诉我?

此功能通过检查URL“$ feedurlstr”

来确定Feed是否有效
// This function determines whether a given post/channel is live or not 
// based on whether url $feedurlstr has $string in it.

    function LiveOrNot($feedurlstr) {
        global $result;
        // create curl resource
        $ch = curl_init();
        // set url
        curl_setopt($ch, CURLOPT_URL, $feedurlstr);
        //return the transfer as a string
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
        // $output contains the output string
        $output = curl_exec($ch);
        // close curl resource to free up system resources
        curl_close($ch);      

        $string = "PP['channel_live'] = true";
        if(strstr($output,$string)) {
        $result = "live";
        } else {
        $result = "notlive";
        }
        return $result;
    }

此函数运行一个SQL查询,该查询根据前一个函数是返回$ result为live还是notlive来更改每个帖子的状态。

// Function runs SQL query based on channel status $result

    function RunChannelLiveQuery() {
        global $key;
        global $post_ids;
        $key = 'feed';
        // This array includes the Post ID to be checked
        $post_ids = array(2263, 2249); 

        foreach ($post_ids as $id) {
        // Wordpress function to pull value out of a "custom field" - spits URL
            $feedurl = get_post_custom_values($key, $id);
            // turns $feedurl into string
            $feedurlstr = implode($feedurl);
            // Find whether feed is live or not
            LiveOrNot($feedurlstr);

            // Performs DB Query based on live or not
            if ( $result == "live" ) {
                mysql_query ("UPDATE 'wp_posts' SET 'post_status' = 'publish' WHERE 'post_id' = '$id'") or die(mysql_error());
            }
            if ( $result == "notlive" ) {
                mysql_query ("UPDATE 'wp_posts' SET 'post_status' = 'draft' WHERE 'post_id' = '$id'") or die(mysql_error());
            }
        }
    }

关于这些功能团伙可能出现什么问题的任何想法?

虽然不是必需的,但您可能希望使用Wordpress API来更新帖子状态

试试这个:

LiveOrNot()功能中删除行

global $result;

RunChannelLiveQuery()中,替换

LiveOrNot($feedurlstr);

通过

$result = LiveOrNot($feedurlstr);
