  • Pass PHP variables without being seen when working with a database generated list

    - by Wilcoholic
    Looking for any help regarding the problem. Here's the deal: I have a database that has a teams table and it contains team_id. On one of my pages, I generate a list of links that contain the team_id of the creator in their get URL. I need the team_id on the next page but can't figure out how to pass it through any other way. Using a form and POST isn't an option because this method would only pass through the last links data on the list. Storing in a session isn't an option either because there is no way to discretely pass the the variables I need to a function to set the session variables. I have tried and it can pretty easily be viewed from viewing the source code. So here's some sample code to see exactly what I'm dealing with. <? if(mysql_num_rows($result2)>0){ ?> <a class="fltrt btn btn-danger btn-small" onclick="test()" href="acceptmatch-exec.php?match_id=<?php echo $match_id; ?>&team_id=<?php echo $team_id;?>&action=cancel">Cancel Match</a> <?}else{?> <a class="fltrt btn btn-success btn-small" href="acceptmatch-exec.php?match_id=<?php echo $match_id; ?>&team_id=<?php echo $team_id;?>&action=accept">Accept Match</a> <?} ?> The code above is generated multiple times on a page via a while loop that was excluded. I want to pass the match_id and team_id variables without being seen anywhere. If I made this a form, it wouldn't pass the correct variables unless there is only one result at the time (not likely). I'm sure there has to be an easy method that is eluding me, so please share thoughts on how to solve this. I feel as though I am not explaining it well enough, but it's not really easy to explain. I basically want something that works like GET but acts like POST and can be hidden from people viewing source code or link locations. Thanks

  • Using functions and environments

    - by Eduardo Leoni
    Following the recent discussions here (e.g. 1, 2 ) I am now using environments in some of my code. My question is, how do I create functions that modify environments according to its arguments? For example: y <- new.env() with(y, x <- 1) f <- function(env,z) { with(env, x+z) } f(y,z=1) throws Error in eval(expr, envir, enclos) : object 'z' not found I am using environments to keep concurrently two sets of simulations apart (without refactoring my code, which I wrote for a single set of experiments).

  • xdebug profiler output strange results

    - by nic28
    I'm using xdebug to profile some PHP code on Windows and using WinCacheGrind/Webgrind to analyse the output, but I'm getting some strange results. Specifically, the total cumulative time for a single method is greater than 100%! How is it possible that more time is spent executing this function's code and all the functions that it calls than the total time it took to execute the whole script? What am I missing here?

  • C++: use array of strings wrapped in namespace?

    - by John D.
    I got the following code, wishing to wrap a group of strings nicely in a namespace: namespace msgs { const int arr_sz = 3; const char *msg[arr_sz] = {"blank", "blank", "blank" }; msg[0] = "Welcome, lets start by getting a little info from you!\n"; msg[1] = "Alright, bla bla bla.."; msg[2] = "etc."; } The code inside works nicely inside a function, but I don't know how to return an array from it. The namespace idea LOOKS fine, but it returns on the last three lines: error: expected constructor, destructor, or type conversion before ‘=’ token Why can't I define the array inside a namespace, do I need to do something first? It's nice because I can call it like printf(msgs::msg[1]) etc. I want to do this I just can't wrap my head around what's wrong :(

  • Bind event to a div appearing

    - by AndyC
    Can I create an event so I can execute some javascript whenever an element with a specific ID becomes visible or appears on the page? The element comes from a remote resource (so isn't in MY html code but appears on page load) and I'd like some code to run when it appears (and only if it appears, it may not appear every load). Thanks!

  • Objective C @autoreleasepool directive

    - by Cemre
    I am reading a book which says (if I am not getting it wrong) wrapping some code with @autoreleasepool statement enables the ARC. First of all is this the case ? My second concern is when I am doing some iOS example programs, although I enable ARC when creating a new project, I never see this directive being used anywhere (in the automatically generated code). Does this mean that ARC is not being used ? Any ideas/pointers is appreciated.

  • The fundamentals of Hash tables?

    - by kylex
    I'm quite confused about the basic concepts of a Hash table. If I were to code a hash how would I even begin? What is the difference between a Hash table and just a normal array? Basically if someone answered this question I think all my questions would be answered: If I had 100 randomly generated numbers (as keys), how would I implement a hash table and why would that be advantageous over an array? Psuedo-code or Java would be appreciated as a learning tool...

  • walking list in KDB/kernel debugger

    - by user291849
    I need to walk a link list in the kernel debugger. How can I determine the head pointer and walk the list? I have a listing and can find the address and location in the code where I check to see if I have a head, so I know the specific code location and address. But not sure how to determine the pointer or how to determine the next element and pointer on the list.

  • How to speed up saving a UIImagePickerController image from the camera to the filesystem via UIImagePNGRepresentation()?

    - by kazuhito0000
    I'm making an applications that let users take a photo and show them both in thumbnail and photo viewer. I have NSManagedObject class called photo and photo has a method that takes UIImage and converts it to PNG using UIImagePNGRepresentation() and saves it to filesystem. After this operation, resize the image to thumbnail size and save it. The problem here is UIImagePNGRepresentation() and conversion of image size seems to be really slow and I don't know if this is a right way to do it. Tell me if anyone know the best way to accomplish what I want to do. Thank you in advance.

  • Assigning a pointer variable to a const int in C++?

    - by John
    I'm wondering if anyone can explain the following to me: If I write int i = 0; float* pf = i; I get a compile error (gcc 4.2.1): error: invalid conversion from ‘int’ to ‘float*’ Makes sense - they are obviously two completely different types. But if instead I write const int i = 0; float* pf = i; It compiles without error. Why should the 'const' make a difference on the right hand side of the assignment? Isn't part of the idea of the 'const' keyword to be able to enforce type constraints for constant values? Any explanation I have been able to come up with feels kind of bogus. And none of my explanations also explain the fact that const int i = 1; float* pf = i; fails to compile. Can anyone offer an explanation?

  • Debugging asp.net suddenly stops

    - by Lieven Cardoen
    I have a strange error. I'm debugging an asp.net site and suddenly it stops. Visual Studio stays in debug mode and my web application stays on running just fine. I found this post on, but I don't think a background thread is causing the problem. There's even a try catch around the code where it usually stops debugging, but the catch is not triggered... Everytime I try it, it stops at a different place in the code.

  • C++ - repeatedly using istringstream

    - by Goffrey
    I have a code for reading files with float numbers on line stored like this: "3.34|2.3409|1.0001|...|1.1|". I would like to read them using istringstream, but it doesn't work as I would expect: string row; string strNum; istringstream separate; // textovy stream pro konverzi while ( getline(file,row) ) { separate.str(row); // = HERE is PROBLEM = while( getline(separate, strNum, '|') ) { // using delimiter flNum = strToFl(strNum); // my conversion insertIntoMatrix(i,j,flNum); // some function j++; } i++; } In marked point, row is copied into separate stream only first time. In next iteration it doesn't work and it does nothing. I expected it is possible to be used more times without constructing new istringstream object in every iteration.

  • OpenMsgStore fails: MAPI_E_NO_SUPPORT or E_ACCESSDENIED

    - by KellyLynch
    I have to support an old C++ program (I am not its author) that uses Extended MAPI to scan mail folders from Outlook 2007. Suddenly the software began meeting problems on one customer's computer by the following scenario: call of OpenMsgStore fails for some folders with code 0x80040102 (MAPI_E_NO_SUPPORT ). for other folders it fails with code 0x80070005 (E_ACCESSDENIED). But other folders opened by OpenMsgStore OK. What can be reason of the problem?

    Hi, if I'm using the sizeof operator and making use of size_t in my code, do I have necessarily have to include the preprocessor directive stddef.h ? I haven't included the stddef.h and my code compiles without warning with both MVS2008 and with Borland C++ BuilderX. Thanks a lot...
