PHP - Session Not Maintaining For The First Time

I have the following session timeout code which should redirect users of a website to a page (session_expired.php) which prints out a message telling the user that his session has expired.  I include this code at the top of every page in the website, that requires user authentication. Code: [Select]

<?php


//address error handling

ini_set ('display_errors', 1);
error_reporting (E_ALL & ~E_NOTICE);


if (isset($_SESSION['LAST_ACTIVITY']) && (time() - $_SESSION['LAST_ACTIVITY'] > 1800)) {
    // last request was more than 30 minates ago
    session_destroy();   // destroy session data in storage
    session_unset();     // unset $_SESSION variable for the runtime
    header("location: session_expired.php");
}
$_SESSION['LAST_ACTIVITY'] = time(); // update last activity time stamp


?>

The session_expired.php page which I will include below, has a login link, which takes the user to a login page (access_denied.php) Code: [Select]


<?php

//address error handling

ini_set ('display_errors', 1);
error_reporting (E_ALL & ~E_NOTICE);




//Set the page title before the header file
$title = 'Session Expired';

require ('header.php'); //need the header

?>









      <div id="content" class="">



<div id="left_content" class="">





</div> <!--closes left content-->





<div id="right_content" class="">

<div id= "right_content_inner_border">


<h5 style ="position:relative;left:660px;top:1px;"> <a style="text-decoration:none" href="access_denied.php">[Login]</a> </h5>


<h3 style ="position:relative;left:110px;top:100px; font-color:blue;"> You Session Expired Due to Inactivity! </h3>


</div> <!--closes right content inner border-->

</div> <!--closes right content-->




</div> <!--closes content-->
















<?php

require ('footer.php'); //need the footer




?>
 
 


Now here lies the problem.  When i set the session timeout to say 60 seconds to test the code, everything seems to work perfectly.  The authenticated page gets redirected to session_expired.php after 1 minute and when the user clicks on the login link, he is taken back to the login page(access_denied.php).    However, when I replace the time with 1800 seconds, the page notice that when I leave the page idle for JUST about 5 minutes, it gets redirected NOT even to the expected session_expired.php page but strangely, directly to the login page(access_denied.php).  What could be going wrong here?  Any hint is appreciated. 

As my title said the question, i want to destroy my session after a particular time if user is being ideal..
currently i am using this code to define my session:

Code: [Select]

session_start();
// Check, if username session is NOT set then this page will jump to login page
if (!isset($_SESSION['myusername'])) {
header('Location: admin.php');
}

$count=0;
$numb=50;
foreach ($sepkeys as $dbkey)
{
for ($page=10;$page<=$numb;$page=$page + 10)
  {
// the if block

$count=$count+1;
 
}

}

I am trying to maintain a separate a count for each key number in the above code.

Eg: key- 574, it searches from pages 10-50 and increments the count by 1.

The problem that I have is the count is continuous. After searching for the first key and moves on to the next key and them I need the count to start from the beginning rather than being continuous.

Eg: key-874 : count = 22, in my case the next key 875 : the count is 23

I need to make it 1.

I removed the if block and several lines because the code is too long.

Can someone please suggest me a way how to do it

If I put into the database this string: Call the wife's son tomorrow

How do I put it in to keep that apostrohe (wife's) and then when I retrieve it, also keep it without it displaying as wife/'s

If I use stripslashes I think that just gets rid of the slash, but I want to KEEP the slash (but still protecting the database so it is not seen as a quote by the php code).

I hope this is clear :-)

I am trying to create a very basic webpage (for local use) that will allow me to add records to a table that I can then come back to at a later date. Essentially, I want a mini spreadsheet in a HTML file. Is this possible?

I know that I could do this using PHP, but I just want this for local use, so I do not want / need to upload it anywhere. Plus, I am not linking to any database, I am hoping just to have the table saved into the HTML file. I currently have a JS script that will add rows to my table (with predetermined information - not 100% what I am wanting), but once I close the window, that information is not saved.

If anyone could at least point me in the right direction, that would be good (hopefully this all makes sense)

Hi,

I have managed to get the code below working with a few tweaks here and there.  However, you can see that I have written a small function in the file name local.php to allow the user to select "English" or "German" in the link on the test.php page.

This works fine but it will only work on that particular webpage.  As soon as I move away from that page the locale will return back to "en_US"(English).  Is there a way I could implement lets say an option dropdown and save the locale across the whole site.

Just in case its relevant I have a MySQL DB available for use if thats appropriate.

local.php
<?php

function english(){

$directory = dirname(__FILE__).'/locale';
$domain = 'messages';
$locale ="en_UK.utf8";
setlocale( LC_MESSAGES, $locale);
bindtextdomain($domain, $directory);
textdomain($domain);
bind_textdomain_codeset($domain, 'UTF-8');

}

function german(){

$directory = dirname(__FILE__).'/locale';
$domain = 'messages';
$locale ="de_DE.utf8";
setlocale( LC_MESSAGES, $locale);
bindtextdomain($domain, $directory);
textdomain($domain);
bind_textdomain_codeset($domain, 'UTF-8');

}

//Pagination and normal view switch 
if (isset($_GET['run'])) $linkchoice=$_GET['run'];
else $linkchoice='';

switch($linkchoice){

case 'English' :
    english();
    break;

case 'German' :
    german();
    break;

default :
    english();
    break;

}

?>


test.php
<?php include("local.php"); ?>
<html><head></head>
<body>
<?php echo "<p><a href='?run=English'>English</a> | <a href='?run=German'>German</a> </p>"; ?>
<br />
<?php echo gettext("Welcome to My PHP Application");
echo "<br />";
// Or use the alias _() for gettext()
echo _("Have a nice day"); ?>
</body>
</html>

Many thanks in advance!

Hey, I want to be able to have a 100x100 thumbnail of pictures I am uploading while cropping the image to maintain the ratio. Right now I am stretching the image and it looks bad but it works. Here is my code...

Quote

$new_thumb = "$new_pic";
$sourcefile = "$target2$pic";
$picsize = getimagesize("$target2$pic");
$source_x = $picsize[0];
$source_y = $picsize[1];

$dest_x = 100;
$dest_y = 100;


$targetfile = "$thumbs$pic";

$pathtofile = pathinfo($sourcefile);
$extension = $pathtofile['extension'];
$jpegqual = 75;

   if($extension=='jpg' || $extension=='jpeg' || $extension=='JPG') {
$source_id = imagecreatefromjpeg("$target2$pic");
$target_id = imagecreatetruecolor($dest_x, $dest_y);
$target_pic = imagecopyresized($target_id,$source_id,0,0,0,0,$dest_x,$dest_y,$source_x,$source_y);
imagejpeg($target_id,"$targetfile",$jpegqual);
}
if($extension=='gif') {
$source_id = imagecreatefromgif("$target2$pic");
$target_id = imagecreatetruecolor($dest_x, $dest_y);
$target_pic = imagecopyresized($target_id,$source_id,0,0,0,0,$dest_x,$dest_y,$source_x,$source_y);
imagegif($target_id,"$targetfile",$jpegqual);
}
if($extension=='png') {
$source_id = imagecreatefrompng("$target2$pic");
$target_id = imagecreatetruecolor($dest_x, $dest_y);
$target_pic = imagecopyresized($target_id,$source_id,0,0,0,0,$dest_x,$dest_y,$source_x,$source_y);
imagepng($target_id,"$targetfile",$jpegqual);
}



How could I change this to make the thumbnails maintain the aspect ratio but still be 100x100?

I have a problem of separating MySQL concatenated info, yet still maintaining their relationship to other arrays in the same order. First off here is the MySQL code:

Code: [Select]
$query ="SELECT report,";
$query.="GROUP_CONCAT(DISTINCT docID) AS docIDs, ";
$query.="GROUP_CONCAT(DISTINCT analyst) AS analysts, ";
$query.="GROUP_CONCAT(DISTINCT region) AS regions, ";
$query.="GROUP_CONCAT(DISTINCT country) AS countries, ";
$query.="GROUP_CONCAT(DISTINCT topic) AS topics, ";
$query.="GROUP_CONCAT(DISTINCT date) AS dates, ";
$query.="GROUP_CONCAT(DISTINCT event) AS events, ";
$query.="GROUP_CONCAT(DISTINCT link) AS links, ";
$query.="GROUP_CONCAT(DISTINCT province) AS provinces ";
$query.="FROM reports GROUP BY report ORDER BY dates DESC, docIDs DESC";
The most important thing is to get all attributes about each report. The thing is, each report can have as many records as it must, in order to store various types of information, like, if multiple analysts are working on the report, then each one saves their own record, but when retrieving these records MYSQL concatenates the records, to make it look to the analysts like this

Report 1 --- Josh, Rebecca --- Philippines

However, my problem is trying to display the reports by country... as you can see http://shoutkey.com/carriage. I have no idea about how to split up the countries, while maintaining their relationship to the $rows pulled from MySQL. I am gonna post the entire code, and let me know if anybody has any ideas.

Code: [Select]
$result = mysql_query($query);

$numrows = mysql_affected_rows();


$current = false;                 
while($row=mysql_fetch_assoc($result)) {
$dates = $row['dates'];
$analysts = $row['analysts'];
$provinces = $row['provinces'];
$topics = $row['topics'];
$regions = $row['regions'];
$countries = $row['countries'];
$reports = $row['report'];
$links = $row['links'];
$events     = $row['events'];

if (!$current){ //first call
echo "<h3><a href=\"#\">{$countries}</a></h3>"; //echo first call
  $current = $countries;
echo "<div>" ;//open content div
}
elseif($current != $countries){ // country has changed
echo "</div>"; //close previous content div
echo "<h3><a href=\"#\">{$countries}</a></h3>"; //echo subsequent countries
    $current = $countries;
    echo "<div><p>" ;//open content div
}


echo $analysts." ----- ".$provinces." ----- ".$reports;
echo "<br /><br />";

}
echo "</div>";
?>
    </div>       

Hi,

I have successfully implemented a master details page with the results aligned in columns linking to a details page.
I wish to maintain the recordID passed from the master details page and make the dynamic text, which reads
Shade
A tree that is capable of.....
in the attached screen shot a link to another details page referencing the same recordID.

The detailspage2.php would look the same as the screenshot except the Shade text and description below will be highlighted, which I can do, there will be a new image and a new image description.  All other dynmaic elements on the page will remain the same.

I tried to simply save as my detailspage.php to detailspage2.php and create a link to detailspage2.php. It linked to detailspage2.php but none of the record info showed up in their respective table cells.

I have all the names desc's, images, etc setup in a table in my database.

Please let me know what code and other info you need to help me out with this procedure.

Thanks.

Any help or suggestion would be appreciated

I am having trouble resolving an error.

Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /home/s519970/public_html/header.php:27) in /home/s519970/public_html/admin/login.php on line 2

 What I can gather is I can't use "header (Location: 'admin.php')" after i've used session_start(). I have tried to replace the header (Location: 'admin.php') with this:

                echo "<script>document.location.href='admin.php'</script>";
      echo "<script>'Content-type: application/octet-stream'</script>";

I've been trying to read up on solutions but haven't been able to get it sorted. If anyone can offer some advice that would be greatly appreciated as im new to php.

Code: [Select]
<?php
  session_start();
  if(isset($_SESSION['user']))

                echo "<script>document.location.href='admin.php'</script>";
echo "<script>'Content-type: application/octet-stream'</script>";
?>

<div id="loginform">

<td><input type="password" name="password" /></td>
</tr>
<tr>
<td colspan="2" align="right"><input type="submit" name="login" value="Login" /></td>
</tr>
</table>
</form>

</div>
I have tried using require_once('yourpage.php'); before my <head></head> tags in the header document where I've specified the html information but this doesn't seem to work. I've been advised to use ob_start("ob_gzhandler"); but I am not sure how to implement this.

Any advice is greatly appreciated!

I'm making a simple login system with MySQL and PHP (very simple, I'm just starting with PHP). The MySQL portion is done, but I need to ensure only people who are logged in can see certain content.

To check if people are logged in, my website checks that they have the $_SESSION['user'] variable set. If it is set, then it lets them continue through the website, if not, it tells them to login. Is that enough security, or can people simply inject a session cookie into their browser to spoof that they are logged in?

My idea was to generate a session key cookie when they login (just a random string of letters and numbers) and store that in the database, then on every page, check to make sure their session key is the same thing that's in the database. Is this necessary? It seems expensive.

hi everyone.

i'm wondering what the best way is to create a session variable and pass it to an iframe.
i need to do something along these lines, but it doesn't seem to pass the ID. Any hints on how i should accomplish this?

Code: [Select]
session_start();
  $_SESSION['ID']=$_GET['ID']; // id from previous page
$ID=session_id();

 <iframe src="iframepage.php?ID=<?php echo $ID; ?>" style="width:680px; height:200px;" noresize="noresize" frameborder="0" border="0" scrolling="Yes" allowtransparency="true" /> </iframe>

PHP date and time function is not showing correct time on my local system

I have the following php code

date_default_timezone_set("Africa/Lagos");

$date = date('d-m-y h:i:s');

echo "Server Time ".$date ."<br>";

echo "The time is " . date("h:i:sa")."<br>";

$current_datetime = date("Y-m-d") . ' ' . date("H:i:s", STRTOTIME(date('h:i:sa')));

echo "Current time1: ".$current_datetime . "<br>";

 

Output

Server Time 21-05-21 09:55:39
The time is 09:55:39am
Current time1: 2021-05-21 09:55:39

 

Expected Output

Server Time 21-05-21 10:55:39
The time is 10:55:39am
Current time1: 2021-05-21 10:55:3

 

Any help would be appreciated.
