Session Variables in Opencart
提问by user984689
Can someone explain where session variables are held?
有人可以解释会话变量的保存位置吗？
I have added some session variables in header.php in the controller, for example:
我在控制器的 header.php 中添加了一些会话变量，例如：
$this->session->data['day']=date("d",strtotime($row['startdate']));
This works when loading the site, and when I click on a product, all the variables are gone, except for the [language], [currency]and [cart]which are set by Opencart.
这在加载站点时有效，当我单击产品时，所有变量都消失了，除了Opencart 设置的[language],[currency]和[cart]。
I guess there is another file or controller file where I set the variables, or where [language], [currency]and [cart]are set but I cannot find it.
我想还有另一个文件或控制器文件，我在其中设置了变量，或者在哪里设置了[language],[currency]和[cart]，但我找不到它。
Thanks in advance.
提前致谢。

Session values are not set in a file. If you want to set a session variable, use
会话值未在文件中设置。如果要设置会话变量，请使用
$this->session->data['variable_name_here'] = 'data value here';
and to retrieve the value you just access
并检索您刚刚访问的值
$this->session->data['variable_name_here']
For example, to echo it use
例如，要回显它使用
echo $this->session->data['variable_name_here'];

Here I would save the variables into a session:
在这里，我将变量保存到会话中：
public function receive() {
$this->session->data['guest_name'] = $this->request->post['name'];
$this->session->data['guest_address'] = $this->request->post['address'];
}
Now in catalog/controller/checkout/guest.phpat indexmethod check for that session variables and if set, store the value in the $this->dataarray for presenting to the template:
现在在catalog/controller/checkout/guest.phpatindex方法中检查该会话变量，如果设置，则将值存储在$this->data数组中以呈现给模板：
if(isset($this->session->data['guest_name'])) { // it is enough to check only for one variable and only if it is set
$this->data['guest_name'] = $this->session->data['guest_name'];
$this->data['guest_address'] = $this->session->data['guest_address'];
}
After that You can simply echo these values in Your template (still checking whether exists):
之后，您可以简单地在您的模板中回显这些值（仍在检查是否存在）：
<?php if(isset($guest_name)) { ?>
<div><?php echo $guest_name . ' - ' . $guest_address; ?></div>
<?php } ?>
Now You should be done while avoiding any undefined variablenotices...
现在你应该在避免任何undefined variable通知的情况下完成...

There is no file that held the session variables. Open cart session are created by using "system/library/Session.php". You can create session like this in open cart.
没有保存会话变量的文件。使用“system/library/Session.php”创建打开购物车会话。您可以在打开的购物车中创建这样的会话。
<?php
$this->session->data['session_name'] = 'session value';
?>
Now you can call this session in any where in open cart like this.
现在，您可以像这样在打开的购物车中的任何位置调用此会话。
<?php
echo $this->session->data['session_name'];
?>

I think i bit late but the main class which handle the sessions is in the system/library/session.php, which have public variable $data and handling the $_SESSION in the constructor. so what ever you put in the $this->session->data it merge.
我想我有点晚了，但是处理会话的主类在 system/library/session.php 中，它具有公共变量 $data 并在构造函数中处理 $_SESSION。所以无论你在 $this->session->data 中放入什么，它都会合并。
Hope it will be beneficial.
希望它会是有益的。
thanks
谢谢

/system/library/customer.php does contain $this->session->data['customer_id'];
/system/library/customer.php 确实包含 $this->session->data['customer_id'];
