How do you use session variables in wordpress?
提问by user1978592
I have the following plugin: http://wordpress.org/support/plugin/wp-session-manager
我有以下插件：http: //wordpress.org/support/plugin/wp-session-manager
I cannot work out how to use the session variables in WordPress. From what I understand by reading, this is how it should be used:
我不知道如何在 WordPress 中使用会话变量。根据我阅读的理解，这是应该如何使用它的：
I have the following on page one (page 1):
我在第一页（第 1 页）上有以下内容：
global $wp_session;
$wp_session['loggedIn'] = 15;
echo $wp_session['loggedIn'];
On the first page, the session variable is working but on the second page, the session variable is not working. Can anyone suggest me where I am going wrong?
在第一页上，会话变量正在工作，但在第二页上，会话变量不起作用。谁能建议我哪里出错了？
Thanks.
谢谢。

Replace:
代替：
global $wp_session;
With:
和：
$wp_session = WP_Session::get_instance();
Make sure you add $wp_session = WP_Session::get_instance();before you try to echo the variable on page 2.
确保$wp_session = WP_Session::get_instance();在尝试回显第 2 页上的变量之前添加。

- Add below code in
function.phpfile
- 在
function.php文件中添加以下代码
function register_my_session(){
if( ! session_id() ) {
session_start();
}
}
add_action('init', 'register_my_session');
- After that you can store value in session variable like
- 之后，您可以将值存储在会话变量中，例如
$_SESSION['something'] = $xyz
