内容导读

互联网集市收集整理的这篇技术教程文章主要介绍了php – 记住用户从一个页面到下一个页面的选择，小编现在分享给大家，供广大互联网技能从业者学习和参考。文章包含17473字，纯文字阅读大概需要25分钟。

内容图文

在我的网站上,用户有几个选项,如语言,日期和地区.当用户点击其中任何一个都很好时,网站会适应特定的选择,但是当他们去另一个页面时他们放弃了所有的选择,如果我找到一种方法来保留他们的整个访问或者也许24小时.

例如：鲍勃进入我的网站,在区域设置下,他点击英国,结果网站适应并显示他英国国旗的结果.然而,当他进入下一页时,他失去了旗帜和他的地区设置,并且必须重新选择他的地区设置.

这是我想要解决的问题.我将发布整个代码以防这可能有所帮助：

这可能是在cookie /会话或类似的东西可行,但我知道我如何将cookie /会话与我编码它的方式结合到此.

除cookie或会话之外的任何其他建议都是受欢迎的.

任何帮助非常感谢.

非常重要的更新
*在下面的建议后我尝试了这段代码：*

<?php
session_start(); //put this at the top of your script on all pages that need to remember
if(isset($_POST['languages']))

什么工作.有什么原因,似乎已经完成了人们告诉我的所有事情？**

解决方法:

会话或Cookie绝对是最好的方式：
问题是你必须有办法将它与用户连接起来.
从技术上讲,您可以将其存储在数据库中,并在用户的计算机上存储一个cookie,该cookie说明要读取哪个数据库条目,甚至存储用户的ip并将其与用户相关联(尽管这是一种非常不可靠的方法).但这对你想做的事情来说可能是一种过度杀伤力.

以下是如何将会话合并到您的代码中：

只发布一种语言

首先,让我们重新格式化您已有的内容.
你有$_POST [‘languages’]实际上是一个包含一个结果的数组.
在这种情况下你也可以把它变成一个字符串并称之为$_POST [‘language’]

当用户最初选择他的语言时,您还必须记住正确地(以单数形式)发布它.

首先,您必须在页面顶部开始会话：

session_start();

接下来,您必须将用户的选择保存到会话变量.

我们将检查用户是否已选择语言(来自$_POST变量),如果是,则将其分配给$_SESSION变量.

if ($_POST['language']) {
    $_SESSION['language'] = $_POST['language'];
}

会话变量的功能与任何其他变量相同,但会在页面之间继续进行,直到会话结束.

现在我们要检查语言是什么

这很简单.在您的示例中,您通过查找用户“已发布”的内容来检查语言是什么：

isset($_POST['languages'])

在我们的新代码中,我们将检查刚刚保存的会话变量：

$_SESSION['language']

选择正确的语言

无需将$_POST [‘languages’]作为数组,然后使用foreach循环遍历它.

一个更简单的方法是这样的：

switch($_SESSION['language']) {
    case "german": //do german suff
    case "english": //do english suff
    etc...
}

此外,您首先检查会话标记是否为空,然后放置一个值(如果不是).
在所有情况之后,您可以跳过该步骤,而不是在最后放入switch(){}内部：

default: //do default language stuff
