WordPress结构化数据插件sitemap1.0问题不断啊！前面逍遥乐说了，有效解决wordpress插件百度结构化数据——百度sitemap1.0一直校验中及sign检测失败的解决方法接下来逍遥乐虽然是验证成功了，却遇到了新的问题！

发布文章或编辑文章时就会出现错误代码，如下图所示：文字为：

Warning: curl_setopt() [function.curl-setopt]: CURLOPT_FOLLOWLOCATION cannot be activated when safe_mode is enabled or an open_basedir is set in /*****/wp-content/plugins/baidusubmit/inc/sitemap.php on line 521

Warning: Cannot modify header information - headers already sent by (output started at /*****/wp-content/plugins/baidusubmit/inc/sitemap.php:521) in /*****/wp-includes/pluggable.php on line 896

解决：

碰到此问题解决办法参考下面方法

当系统开启safe_mode和 open_basedir,在程序中使用以下语句

curl_setopt($curl, CURLOPT_FOLLOWLOCATION, 1);

并且遇到301,302状态码时会出现错误

[11-Oct-2010 14:17:41] PHP Warning: curl_setopt(): CURLOPT_FOLLOWLOCATION cannot be activated when in safe_mode or an open_basedir is set in msn.class.php on line 819

解决方法是在curl语句用不使用curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true),在php函数中自定义一个curl_redir_exec函数

具体代码如下：

//follow on location problems workaround
// modified by yanggg QQ 346767073 
// 参数  gettype = 0 表示 读取的是 html内容，不包括head    , type=1 表示读取 内容和head
function curl_redir_exec($ch, $gettype=0)
     
{
     
	//echo 'curl_redir_exec............';


    static $curl_loops = 0;     
    static $curl_max_loops = 20;     
    if ($curl_loops++>= $curl_max_loops)     
    {     
		$curl_loops = 0;     
		//echo '超出次数了';
		return FALSE;
     
    }
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); 
    curl_setopt($ch, CURLOPT_HEADER, true);      
	// 参数  gettype = 0 表示 读取的是 html内容，不包括head
	$data = curl_exec($ch);   
    if($gettype === 0 ){
  
		//echo $data;
		//var_dump( explode("\n\n", $data, 2));
		$data = str_replace("\r", "", $data);
		//echo "------strpos ------:" .strpos($data, "\n\n");
		//var_dump(explode("\n\n", $data,2));
		$aa = explode("\n\n", $data,2);
		//原版这里错了
		//list($header, $data) = explode("\n\n", $data, 2);     
		$header = $aa[0];
		$data = $aa[1];
		//echo "---------header-------------:" . $header;
		//echo "---------data-------------:" . $data;
    }else{
		//不用处理
	}
	
	$http_code = curl_getinfo($ch, CURLINFO_HTTP_CODE);     
    if ($http_code == 301 || $http_code == 302)     
	{
	 
		$matches = array();		 
		preg_match('/Location:(.*?)\n/', $header, $matches);		 
		$url = @parse_url(trim(array_pop($matches)));
		if (!$url)     
		{
			//couldn't process the url to redirect to		 
			$curl_loops = 0;		 
			return $data;


		}
		$last_url = parse_url(curl_getinfo($ch, CURLINFO_EFFECTIVE_URL));
		if (!$url['scheme'])
		$url['scheme'] = $last_url['scheme'];
		if (!$url['host'])
			$url['host'] = $last_url['host'];
		if (!$url['path'])
			$url['path'] = $last_url['path'];
		$new_url = $url['scheme'] . '://' . $url['host'] . $url['path'] . ($url['query']?'?'.$url['query']:'');
		curl_setopt($ch, CURLOPT_URL, $new_url);
		return curl_redir_exec($ch);
	} else {
		$curl_loops=0;
		return $data;     
    }
     
 }

然后使用

curl_redir_exec($ch);替换512行的curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);语句

其他wrordpress的程序调用

if (ini_get('open_basedir') == '' && strtolower(ini_get('safe_mode')) != 'on'){ 
curl_setopt($curl, CURLOPT_FOLLOWLOCATION,1);
$html = curl_exec($curl); // execute the curl command
}else{
$html = curl_redir_exec($curl);
}
