Php 哈希、浏览器中的cookie和数据库中的存储不工作
我将按照本教程介绍如何使用数据库连接构建注册表表单。出于某种原因，在浏览器和数据库中存储哈希Cookie对我来说不起作用，即使在代码中包含了记住选项，它仍然好像什么都不做 记住选项从3:26:00开始，之后我做了所有事情，就像他显示的那样，但在某个点上，Cookie散列不会显示在我的浏览器中 我不知道我做错了什么，也许有人能帮我指出 我知道这个教程已经过时了，但在某种程度上，我喜欢这个家伙解释他在做什么的方式，我在这方面是个傻瓜，但必须在某个时候开始 我在Hash：：make函数方面遇到了一些问题，因为PHP7.2.2现在的工作方式不同了，但是我用不同的方式解决了这些问题，正如教程所示，现在我想我在Hash.PHP文件方面遇到了问题 我做的另一件事是，我每周安装一次WORDPRESS，并且不得不在数据库中进行一些特权更改，这可能是它不能正常工作的原因吗？？，即使我没有在数据库中使用WORDPRESS生成的表，但仍然在按照教程创建的同一个表上工作 这是Config.php文件中的代码Php 哈希、浏览器中的cookie和数据库中的存储不工作,php,Php,我将按照本教程介绍如何使用数据库连接构建注册表表单。出于某种原因，在浏览器和数据库中存储哈希Cookie对我来说不起作用，即使在代码中包含了记住选项，它仍然好像什么都不做 记住选项从3:26:00开始，之后我做了所有事情，就像他显示的那样，但在某个点上，Cookie散列不会显示在我的浏览器中 我不知道我做错了什么，也许有人能帮我指出 我知道这个教程已经过时了，但在某种程度上，我喜欢这个家伙解释他在做什么的方式，我在这方面是个傻瓜，但必须在某个时候开始 我在Hash：：make函数方面遇到了一些问

无论如何，谢谢。代码会发生什么变化？这里有很多代码。您还应该在任何地方使用参数化DELETE*
不正确，您删除的是整行，而不是列，因此*
不应该在那里。您可以将此简化为吗？对不起，我没有3个小时的时间来计算假设会发生什么。有数百行代码，我很确定其中大多数与您的问题无关。正如MaxvonHippel所说，您必须将代码减少到最小的示例，这样我们就可以更容易地提供帮助you@CROZET我很想这样做，但我想我会留下一些重要的信息，因为我不知道我可以删除什么，我必须保留什么
