session-variables

问题 I'm making a login page and for some reason the session will not persist between where I set it and the page where I am forwarding to. I can comment out the header in the page where the session was initialized and see that the session has the data in it. However, when I do a print_r in the target page, the session is empty. I have already made sure that session_start is called. There is only one domain for this site and my browser is set to accept cookies. I can forward to any other page and

问题 I'm encountering a very new and strange issue. Usually session_start(); is initiated at the top of every page but in my case it's only serving the purpose when it is placed below a included database connection file, something like, <?php include 'connection.php'; session_start(); ?> session_start(); doesn't work when it is put reversely like, <?php session_start(); include 'connection.php'; ?> Basically the values were initiated and stored in session variables in another file and these should

问题 I have a subnav bar in my module created from a view partial via a helper. Here is the config in module.config.php: 'navigation' => array( 'default' => array( array( 'label' => 'Create', 'route' => 'mymodule\Create', ), array( 'label' => 'View', 'route' => 'mymodule\view', ), array( 'label' => 'Search', 'route' => 'mymodule\search', ), array( 'label' => 'Log Off', 'route' => 'mymodule\logoff', ), ), ), ); So here is my problem, I don't just want to redirect the user to the login page, I want

问题 First off, this is my own project, not a homework assignment. Here's the situation. I have a web application (ASP.NET w/ MVC 5) and I use the session to store certain things (e.g. user info). Now, there are two tabs open, each on one part of the page. We will call them Tab A and Tab B. Here's the scenario: Tab A is open to Page A Tab B is open to Page B In Tab B, the user does an action which requires the update of a session variable. Thus, I write the new data to the session variable via an

问题 I have a shopping cart app using a temporary MySQL table to store cart contents. Each row of the cart table has the session value saved to uniquely identify that row. I'm setting the initial value using the following: $session_id = session_id(); Each time a user adds an item to their cart, I run a query to count the number of products in their cart and save that value using the following: $_SESSION["total_cart_products"] = $cart_total_products['total_cart_products']; On the web site, the cart

问题 I want to use a session variable to store some data in my mvc 4 application but I'm a little unsure of the sessions life cycle. I have the timeout set and obviously it dies when that runs out but I'm curious as to what happens (and how I can control what happens) when: The browser closes Page is refreshed User logs out (I'm assuming I need to deal with this one manually) 回答1: I think aside from all the comments (which I think are all answers), the (other) key item to think about is that at

问题 I'm looking for a client-side JS library to store session variables. I'd like a library that supports alternative storage medium, e.g. cookies when available with fallback on other techniques. For instance, I found this one (but the last update is in 2009): http://code.google.com/p/sessionstorage/ I'm not interested in security (apart a bit of data isolation among applications), as I'm not going to store sensitive data. To give an example of use case, I want to display a message "Chrome user?

问题 I declared in master page load: Session["sessionString"] = "stringX"; in my web page on load also, i call it string sessionString= (string)Session["sessionString"]; i debug and value in web page is "" what is wrong? 回答1: JW Lim is correct...content page's load event will fire before Master page load. @user3445314 , you can use "Session_Start" event in Global.asax and set values same as you set in master page. "Session_Start" event fires first and then your content page load event occur. I

问题 I've had this twice now. Out of the blue, my log-in system stops working, and by debugging I find out the $_SESSION variable does not survive the log-in process. Then, without an obvious cause, it resumes working. Here's the flow: User logs in at index.html , form submits to login.php ; login.php does basic sanity, isset and empty checks, then checks the credentials with the database. If the email address and password are correct (i.e., exist in the database) put them in the $_SESSION
