Question

我正在做的是抓取Feed并插入每个Feed项的数据。请参阅下面的我正在使用的代码。好。所以我运行带有查询的页面，它将feed加载到simplexml中，然后在feed中插入前两项，但是当它到达第三项时我得到一个错误。请参阅下面的错误。

我正在使用PHP5＆amp; MySQL 5.0.4

PHP代码：

$xml = simplexml_load_file($feed['url']);

foreach($xml->channel->item as $item)
{                       
    $this->query = $this->db->query("
    INSERT INTO `feed_items`
    (`feed_id`, `guid`, `publish_date`, `update_of`, `link`, `title`, `description`, `comments_link`)
    VALUES
    ('{$feed['id']}', '{$item->guid}', '{$item->pubDate}', NULL, '{$item->link}', '{$item->title}', '{$item->description}', NULL)
    ");
}

错误：

A Database Error Occurred
Error Number: 1064

Answer 1

您需要在（至少）'description'字段中转义引号，然后再将其输入db：

foreach($xml->channel->item as $item)
{                                       
    $this->query = $this->db->query("
    INSERT INTO `feed_items`
    (`feed_id`, `guid`, `publish_date`, `update_of`, `link`, `title`, `description`, `comments_link`)
    VALUES
    ('{$feed['id']}', '{$item->guid}', '{$item->pubDate}', NULL, '{$item->link}', '{$item->title}', '" . mysql_real_escape_string($item->description). "', NULL)
    ");
}

虽然我不确定mysql_real_escape_string现在用的是什么。

Answer 2

'kyct: @jtkendall Edit your $config['permitted_uri_chars']? That seems risky though. Is it a static page that you're serving?', 'kyct: @jtkendall Edit your $config['permitted_uri_chars']? That seems risky though. Is it a static page that you're serving?'

您需要转义单引号，如下所示：

"INSERT INTO `feed_items`
(`feed_id`, `guid`, `publish_date`, `update_of`, `link`, `title`, `description`, `comments_link`)
VALUES
('{$feed['id']}', '{$item->guid}', '{$item->pubDate}', NULL, '{$item->link}', '" . mysql_real_escape_string($item->title) . "', '" . 
 mysql_real_escape_string($item->description) . "', NULL)
";

执行INSERT查询时获取MySQL错误1064
