php - 执行 INSERT 查询时获取 MySQL 错误 1064

Question

我正在做的是抓取一个提要并从每个提要项中插入数据。请参阅下面我正在使用的代码。好的。因此，我运行带有查询的页面，它将提要加载到 simplexml 中，然后我在提要中插入前两个项目，但是当它到达第三个项目时出现错误。请参阅下文了解我遇到的错误。

我正在使用 PHP5 和 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

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'permitted_uri_chars']? That seems risky though. Is it a static page that you're ' at line 4

INSERT INTO `feed_items` (`feed_id`, `guid`, `publish_date`, `update_of`, `link`, `title`, `description`, `comments_link`) VALUES ('2', 'http://twitter.com/kyct/statuses/4131154118', 'Sun, 20 Sep 2009 20:54:41 +0000', NULL, 'http://twitter.com/kyct/statuses/4131154118', 'kyct: @jtkendall Edit your $config['permitted_uri_chars']?

在将其输入数据库之前，您需要(至少)转义“描述”字段上的引号:

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 是不是现在用得那么多。
