session variables - PHP HTTP_REFERRER - how to detect last page? -

-

I need to figure out where the user has just clicked - as my AJAX content is from the source page It is required to display differently depending on the basis

If it is to go to about.php, then it needs to be the data only, but if it is going to main-main.php So it should be the whole middle column so that it needs a top / footer cover. Data

The HTML phone via AGX is organized in a PHP page which uses this code to see who is asking, and then formatting the HTML response properly. 

  $ array [] = "/cf/about.php"; $ Array [] = "/cf/about/about-main.php"; $ Array [] = "/cf/about/other-page.php"; $ Ispage = ""; Forex currency ($ value $ value) {if ($ _SERVER ['HTTP_REFERER']! = $ Value) {$ ispage = ""; } And {$ ispage = "woot"; }} If ($ ispage == "woot") {$ echo $ content; } Else {include_once 'about-header.php'; Counterpart $ content; Include_once 'about-footer.php'; }

The problem is ... HTTP_REFERER looks a bit hit and miss. It works fine while working on the network, but I have tried it at home on my computer and it has failed to work clearly - the results are horrible: o

Is there someone else receive mode? I think the session variable can be used, but then I did not get much experience of that!

Any and all hints / suggestions are appreciated;) Thanks!

Edit:

This page is actually an employee profile page. It is about its general condition. PHP and the second column detector displays a grid of thumbnails, when clicked, load the profile through AJAX on that place. All good and simple-back buttons reload the grid of photos.

The problem is that every staff member also needs a stable page. I have made / staff-name.php about them, though the content is the same. I want the server to know that a person / staff-name has come to the FPP and if so, wrap the header / footer around it.

If the request comes from the photo grid i.e. ajax) then it does not require header / footer cover.

Is that obvious? : O

1) If AJAX request - no wrapper 2) If no AJAX request - Add Header / Footer Cover

Then about / staff-name.php displays content about it / staff-name.php About AJAX calls through Do you? FromAjax = 1

Then about / in the staff-name.php file: 

  if (isset ($ _REQUEST ['ajax']) {$ content ; } Else {include_once 'about-header.php'; Counterpart $ content; Include_once 'about-footer.php'; }

c# - ListView onScroll event -

-
I am programming a simple C # application, and I need a Scallow event on the list view. So I inherited the original ListView class created in ListviewEx witch. I found out how to locate the scroll message from WinAPI and I modified the WndProc method. Now I have this WndProc: protected override zero WndProc (Ref message message) {base.WndProc (Ref I); If (m.msg == WM_VSCROLL) {onScroll (This, New EventArgs ()); }} But the problem is, I do not know how to know about scrolling information. This data should be in wParam, but there is a LOWORD macro ++ like in C in C # and I switch to find the criteria like SB_ below, SB_ENDSCROLL, SB_PAGEUP etc. there any way Need to change the LOWORD macro from C #? Or any other way to find the necessary parameters about scrolling? You can define the WParam constants as the following: Private const int WM_HSCROLL = 0x114; Private Constant WM_VSCROLL = 0x115; Private contact int SBHOZZ = 0; Private Consultant SB_VERT = 1; Private Con...

Linux Terminal Problem with Non-Canonical Terminal I/O app -

-
I have a small app written in C to run on Linux. Part of the app accepts user-input from keyboard , And it uses non-canonical terminal mode so that it can respond to each keystroke. The section of the code that accepts input is a simple task that is called repeatedly in the loop: char get_input () {char C = 0; Int res = reading (input_tamille, & amp; c, 1); If (RSS == 0) 0 returns; If (res == -1) {/ * snip error handling * /} return c; } It reads a letter from the terminal if there is no input within a given time limit, (c_cc [VTIME] value in the vocabulary structure), read () 0 And get_input () is called again It all works very well, I have recently discovered that if you run this app in a terminal window, and then the app Close the terminal window without ending, the app will not exit Received, but CPU intensive launches into an infinite loop, where the read () returns 0 without waiting continued. So how can I get out of the apple if it runs from the terminal win...
