如何将所有表单字段更新到数据库
谢谢

打印的结果($\u GET);是:

在我的情况下,还有什么能起作用?有人有任何链接/教程/文章吗?我哪儿都找不到。是否有其他方法将所有字段提交到数据库?Lucifer
你说你买了一个脚本,为什么不先联系你买它的人来解决你的问题呢
我担心的是,您列出的代码很少,因此我们无法帮助您,因为您只是简单地说“它不起作用!请帮助我解决它!”,我们将帮助您。向我们展示表单代码和处理代码
您确定该表单是作为$\u GET
提交的吗?您确定这些变量在表单中被称为$items[]
如果我正在解决这个问题,或者至少寻求帮助,我会列出以上所有代码,并添加大量调试添加内容,如:
/*comment*/
标记以注释掉SQL inser部分(因为您不想在每次测试时清除所有这些内容)var\u dump
标记以输出尽可能多的变量Firefox Firebug
进行调试更新 11/23/2010 /checkout.php 我已经快速回顾了您的设置,您正在使用AJAX表来管理搜索/显示您的产品。你可以尝试几种方法
action=“POST”
。将实际提交按钮添加到结帐表单中,您只有更新数量的Update
按钮除了为您做一些咨询之外,没有办法“快速”告诉您要更改的内容和位置,这将需要一些时间来修改,但是我在上面列出了两个选项,如果您愿意,您可以处理。一个
$\u的项目得到了什么收益?你能把它贴在这里吗?当然,我会马上做的嗯,我试过var_dump,但我认为它不起作用,页面上没有显示其他内容。我试过:var_dump($_GET['items');你最近的编辑使得这个问题从长远来看毫无意义;只是为什么?谢谢。我很感激你删除一些品牌/网站名称,这很好,但如果问题可以解决,我们将不胜感激;pThank you Jakub,我之前添加了完整的代码作为不同的答案,但是没有一个答案能够帮助解决问题,最终人们不再返回页面。我试图避免同样的问题,通过看看是否有人知道任何其他方法来解决这个问题。但是我会再次发布完整的代码。完成。代码添加。请注意,由于昨晚给出的建议,foreach代码已经更改,但仍然不起作用。请注意,SQL代码很好,它已经单独进行了测试。我不能从我买的脚本(只是一个表格脚本)的作者那里得到任何形式的支持,因为他们想向我收取支持费用,这不是一个选项,他们甚至还没有回复我一个月前发送的电子邮件。
foreach($_GET['items'] as $p=>$q)
{
// Update in database. This sql query has been tested, so I know it works, which means that the problem lies within the foreach loop, since it only stopped working when I added the foreach loop to update all form fields.
