I have no coding experience whatsoever. I am using some code that someone gave me so that my login will timeout. However, once it times out, I can't immediately log back in. A few days later, if I try again, I can. Can anyone help me on how I can modify this code so that I can immediately log in after it times out?
Thank you so much for you help!
This is what I have in place:
<?php
session_start();
if(!isset($_SESSION['logintime'])){
$_SESSION['logintime'] = time();
}else {
if(time() > $_SESSION['logintime'] + 15 * 60){
unset($_SESSION['username']);
}else{
$_SESSION['logintime'] = time();
}
}
if (!isset($_SESSION['username']))
{
header('Location: ./mealplans.php');
exit;
}
?>
Not sure that altering this code will have the effect you want. However you could play with the bit that says '15 * 60' - that will mean 15 minutes.

I had some trouble formulating the Question title, please make an edit if you have a better alternative.
I have a Login procedure to which I add a timeout:
private func startTimeout() {
self.timeoutActive = true
DispatchQueue.main.asyncAfter(deadline: .now() + 20) {
[weak self] in
guard let weakSelf = self else {
return
}
if weakSelf.timeoutActive && !weakSelf.loggedIn {
weakSelf.onError("Login timed out")
}
}
}
I have designed the Login procedure so that if we for any reason need to log in again (for example after logging out, or after the login process determined that there missing or wrong credentials), we end up in the same instance of the class that performs the Login.
Now, as far as I see, we can never prevent a scheduled block from executing, only prevent it by using some flags, which is what I have done with the timeoutActive flag. This works like a charm.
However, I run into a problem if the second Login is timed exactly so that the Previous dispatch block executes after the new Login process is started (When the new login procedure is initiated, the timeoutActive flag is once again set to true). The new Login receives a Timeout that is not correct.
I have been thinking about different ways to solve it, and tried a few, but couldn't get any of them to work.
I had an idea to use performSelectorAfterDelay instead of GCD, which is cancellable, but not available in Swift (3).
I also played with the thought of having some unique block ID with a list of blocked block IDs - but it just seems overkill.
I also had an idea about comparing the current dispatch time (.now()) in the block with the original deadline (.now() + 20) and see if it matches, but I don't know how exact this deadline is and it feels unstable.
The only idea I'm left with is making some kind of Task like object around the Login procedure itself, with the timeout included and create a new instance of that task for different Logins. Seems like a bit of work and I'd prefer if I found an easier way.
Has anyone encountered this type of situation before and have a solution?
So this is what I made from Dan's comment on the Question:
private var timeoutBlock: DispatchWorkItem? = nil
private func startTimeout() {
self.timeoutBlock = DispatchWorkItem(block: { [weak self] in
guard let weakSelf = self else {
return
}
if !weakSelf.loggedIn {
weakSelf.onError("Login timed out")
}
})
DispatchQueue.main.asyncAfter(wallDeadline: .now() + 20, execute: self.timeoutBlock!)
}
And using self.timeoutBlock?.cancel() when leaving the ViewController or completing the process. This works as expected!
Hi I'm starting to become a regular on here but if any can help me with the following. I want to test to see if a user is using a reset password and have the following:
if FIREBASE_REF.authData.providerData["isTemporaryPassword"] == true {
// run some code
}
but xcode is saying expression expected, if anyone knows the correct syntax I would appreciate it.
Thanks
Think I have now got it sort and the solution is as follows for anyone else who is struggling with this:
let handle = FIREBASE_REF.authData.providerData["isTemporaryPassword"] as? Bool
if (handle == true) {
// run code here.
}
I am working on vungle video integration in cocos 2d and and running the ad successfully.
In app i want to provide some points for watching video.. which i can set up.. but the problem is how to check whether the user has watched the video or close it ..
https://v.vungle.com/dev/ios
I am using the above help.. but not able to make it work..Please help me in checking whether app is ads are close or watched completely
- (void)vungleSDKwillCloseAdWithViewInfo:(NSDictionary *)viewInfo willPresentProductSheet:(BOOL)willPresentProductSheet {
//Verify that the view was completed before rewarding the user
BOOL completedView = [[viewInfo valueForKey:#"completedView"] boolValue];
if (completedView) {
//View was successfully completed, do your stuff...
}
}
Few months back I did use vungle. Check below code, that worked for me
-(void)vungleMoviePlayed:(VGPlayData*)playData
{
if(playData.movieTotal == playData.movieViewed)
{
printf("Video fully watched\n");
mSeenVungleVideo = true;
}
else
{
printf("Player aborted video at middle\n");
}
}
This seems to have changed since NatureFriend's answer. It's now:
- (void)vungleSDKwillCloseAdWithViewInfo:(NSDictionary*)viewInfo willPresentProductSheet:(BOOL)willPresentProductSheet;
{
// video done here.
}
It's possible at this point it will show a "Product Sheet". If you want to know when that closes, you can implement this delegate:
- (void)vungleSDKwillCloseProductSheet:(id)productSheet
{
// product sheet closed here
}
I try to implement following logic (a kind of pseudo-code) using pthread:
pthread_mutex_t mutex;
threadA()
{
lock(mutex);
// do work
timed_lock(mutex, current_abs_time + 1 minute);
}
threadB()
{
// do work in more than 1 minute
unlock(mutex);
}
I do expect threadA to do the work and wait untill threadB signals but not longer than 1 minute. I have done similar a lot of time in Win32 but stuck with pthreads: a timed_lock part returns imediately (not in 1 minute) with code ETIMEDOUT.
Is there a simple way to implement the logic above?
even following code returns ETIMEDOUT immediately
pthread_mutex_t m;
// Thread A
pthread_mutex_init(&m, 0);
pthread_mutex_lock(&m);
// Thread B
struct timespec now;
clock_gettime(CLOCK_MONOTONIC, &now);
struct timespec time = {now.tv_sec + 5, now.tv_nsec};
pthread_mutex_timedlock(&m, &time); // immediately return ETIMEDOUT
Does anyone know why? I have also tried with gettimeofday function
Thanks
I implemented my logic with conditional variables with respect to other rules (using wrapping mutex, bool flag etc.)
Thank you all for comments.
For the second piece of code: AFAIK pthread_mutex_timedlock only works with CLOCK_REALTIME.
CLOCK_REALTIME are seconds since 01/01/1970
CLOCK_MONOTONIC typically since boot
Under these premises, the timeout set is few seconds into 1970 and therefore in the past.
try something like this :
class CmyClass
{
boost::mutex mtxEventWait;
bool WaitForEvent(long milliseconds);
boost::condition cndSignalEvent;
};
bool CmyClass::WaitForEvent(long milliseconds)
{
boost::mutex::scoped_lock mtxWaitLock(mtxEventWait);
boost::posix_time::time_duration wait_duration = boost::posix_time::milliseconds(milliseconds);
boost::system_time const timeout=boost::get_system_time()+wait_duration;
return cndSignalEvent.timed_wait(mtxEventWait,timeout); // wait until signal Event
}
// so inorder to wait then call the WaitForEvent method
WaitForEvent(1000); // it will timeout after 1 second
// this is how an event could be signaled:
cndSignalEvent.notify_one();
I'm writing Windows Phone 8 app that needs to get location of device (do not track changes, just get location). I added next code to the method OnNavigatedTo() of my start page but after launching app, the progress indicator does not hide even after 10 seconds timeout. But if I navigate to another page and then go back, everything works fine. This happens on the emulator, I don't have a real device. What am I doing wrong?
protected async override void OnNavigatedTo(NavigationEventArgs e)
{
if(_geoPosition == null)
{
try
{
var geolocator = new Geolocator();
geolocator.DesiredAccuracyInMeters = 50;
_progressIndicator = new ProgressIndicator
{
IsIndeterminate = true,
Text = "Getting current location, please wait...",
IsVisible = true
};
SystemTray.SetIsVisible(this, true);
SystemTray.SetProgressIndicator(this, _progressIndicator);
_geoPosition = await geolocator.GetGeopositionAsync(TimeSpan.FromSeconds(5), TimeSpan.FromSeconds(10));
_progressIndicator.IsVisible = false;
SystemTray.SetIsVisible(this, false);
}
catch (UnauthorizedAccessException)
{
MessageBox.Show("Location is disabled in phone settings");
}
}
}
Thanks!
UPD: just tried to add this code to empty project and it works fine. Tried to comment out some parts of OnNavigatedTo that I did not include to the snippet and found out that the reason somewhere in initialization of data source for this page. I'm sorry for false alarm.
Your code works fine for me, try the classic restart VS and the projecy!
The code should work, tested it with an emulator and a device (nokia 820).
Best of luck
