使用jdatabase更新数据库中的记录

问题描述

如何使用jdatabase更新Joomla3中的记录.这是我到目前为止所拥有的.

How do to use jdatabase to update a record in Joomla3. Here is what i have so far.

$db =& JFactory::getDBO();
$query = $db->getQuery(true);
$query->update('#__test AS h');
$query->set('h.name = 'apple', h.description= 'orange', h.url = 'bannana'');
$query->where('h.id=1');    
$db->setQuery($query);

我缺少一些简单的东西吗?

Am i missing something simple?

推荐答案

我也花了整整一天的时间把头撞在墙上.您的位置非常接近，但是您只需要进行一些细微的调整即可.

I just spent the day banging my head against the wall with this too. You're very close, but you just need some minor tweaks.

$query->set('h.name = 'apple', h.description= 'orange', h.url = 'bannana'');

应为(请注意引号):

$query->set('h.name = "apple", h.description= "orange", h.url = "bannana"');

也:

$db =& JFactory::getDBO();

将在开发人员模式下引发严格标准"警告.只需取下&"号即可.

will throw a "Strict Standards" warning in developer mode. Just remove the ampersand.

遗失的部分:

try {
    $result = $db->execute();
} catch (Exception $e) {
    die($e->getMessage());
}

P.S.我知道这个答案有点晚了，所以希望您现在已经解决了您的问题.我将这个答案发布给以后遇到它的人，但在Joomla的拙劣文档中找不到解决方案.

P.S. I realize this answer is a bit late so I hope that you've solved your problem by now. I am posting this answer for those who come across it later and can't find the solution in Joomla's shitty documentation.
