我正在爲一個電視wordpress網站(www.canal-en-vivo.com)工作幾個php函數,它根據頻道Feed是直播還是根據頻道Feed改變了發佈到草稿的帖子(即頻道)的狀態,或者不。我把以下兩個函數放在一起,但它們似乎不起作用。你們可以看看通用的代碼結構,並告訴我,如果你看到結構有點奇怪嗎?這些功能有什麼問題?
該功能確定飼料是否是通過檢查URL直播或不是「$ feedurlstr」
// 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 $result;
}
而這個函數運行的SQL查詢其改變狀態基於先前的功能是否返回$每個崗位結果是活的或不活潑的。
// 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' = '$id'") or die(mysql_error());
}
}
}
關於這些功能可能出錯的任何想法幫派?
冷若冰霜,感謝您的幫助!我做了更改,但我收到以下SQL錯誤:'您的SQL語法中有錯誤;檢查與您的MySQL服務器版本相對應的手冊,以便在''wp_posts'SET'post_status'='draft'WHERE'post_id'='2263''第1行附近使用正確的語法任何想法? – Alberto 2011-03-17 20:20:58
您不應該在表名和字段名稱周圍添加單引號。只有使用反引號('')是可能的。然後,你的第一個查詢字符串應該看起來像「」UPDATE wp_posts SET post_status ='publish'WHERE post_id ='$ id'「'。查看MySQL手冊獲取更多細節。 – 2011-03-17 20:49:53
這是正確的冷霜。現在它聲稱DB中沒有post_id列'Unknown'列'post_id'in'子句'Odd ... – Alberto 2011-03-17 20:54:59
