PHP - Destroy Session When Browser Is Closed

what would be the best way to
automate/force session destroy and cookie erase
i have a facebook iframe, with facebook login which gets the activation token
now the user is not logged out from the login script after he logs out of facebook.

any ideas how to force cookie timeout without a logout button?

im playing with
Code: [Select]
<?php
session_start();

//Global User Object Var
//loggedInUser can be used globally if constructed
if (isset($_SESSION['userCakeUser'])) {
$obj = casttoclass('stdClass', $_SESSION['userCakeUser']);
$_SESSION['userCakeUser'] = $obj;

$_SESSION['start'] = time(); // taking now logged in time
$_SESSION['expire'] = $_SESSION['start'] + (1 * 60) ; // ending a session in 1 minute
}
if(isset($_SESSION["userCakeUser"]) && is_object($_SESSION["userCakeUser"]))
{
$loggedInUser = $_SESSION["userCakeUser"];
}
?>

Hi Everyone,

I wonder if somebody could help me. I have been at this for hours and am really struggling.

I have a timer which I have set up for a quiz.  The quiz opens in a javascript shadow box.  When the quiz is opened a session variable for the timer is set up to keep track of the time. 

What I need is for this session variable to end when the shadow box is closed. I have a onClose hook to peform actions when the shadow box is closed which is in javascript.

Obviously I cannot end the session variable in the javascript function due to js being client side and php being server side.

Has anyone any suggestions how I can resolve this issue.

I need to end this session variable as if the user exits the quiz and then selects another quiz to do the timer uses the current time session rather than assigning the new time value for that particular quiz.

Thanks in advance.

OK, I'm nearing the end of a very long chat project and I have one last hurdle to jump, I've saved this task to the near end because I thought it would be a problem as I have no idea what to do or where to start. The problem is exactly what is said in the subject title.

I have looked into JavaScript options such as "onbeforeunload" but that is just BAD.

The login is controlled by sessions, so when the user closes the browser, the session is ended, but data in the database says different, cookies are not an option I'm afraid.

I've had an idea that if I create a special account (or a few) and always leave these accounts logged in, they can check if a user has been inactive for a certain period of time, and then run queries to change things, I know this sound odd but maybe I will not have to create these accounts but general accounts that people make will be able to do this for me, without them even knowing.

Please help, any ideas, suggestions, logic or methods that you think will help will be great.

Thanks.

I made a bug which caused endless loop and endless printing.
When I noticed that, I closed the browsers tab, fixed the bug, open a new tab and re-run.
I was assuming the server would start from the beginning, but instead I noticed that some variables were active and the program continued from where it stopped.
How can I make the program to stop when the client tab is terminated?

hey guys, I am trying to setup a session for a filter  , I have a button that the user can click on or off, the button starts off but when the user clicks on it a new session starts and it stays on until the user clicks it again to turn it off or when the browser sessions ends... Any help is welcome, thanks guys, you are the best   

Hi, i m playing arround with php sessions and just started afew testing on it (i never actually used them so i m discovering something new) and i would like to know how can you terminate an PHP Session without closing your browser. For testing i did this small code, just to see the behavior:

Code: [Select]
<?php
    session_start();
    $id = session_id();
    echo $id;
    session_unset();
    session_destroy();
?>

The code above seens only to kill the $_SESSION's variables but what i would like is to Kill the PHPSESSID cookie/session cookie. is there anyway you can achive that? thanks in advance

My code below, i already imagedestroy($newimage)... but i'm not sure if i should be destroying $oldimg as well? Any thoughts?


$newimg = imagecreatetruecolor($sizeA,$sizeA) or die('Problem In Creating image');

$background = imagecolorallocate($newimg, 255, 255, 255);

imagefilledrectangle($newimg, 0, 0, $sizeA, $sizeA, $background);

$oldimg = imagecreatefromjpeg($source)or die('Problem In opening Source Image');

imagecopyresampled($newimg,$oldimg,0,$move,0,0,$sizeA,$new_height,ImageSX($oldimg),ImageSY($oldimg)) or die('Problem In resizing');

imagejpeg($newimg,$s1DIR,90) or die('Problem In saving');

imagedestroy($newimg);

Hi guys,

I'm having a problem with destroying Cookies in IE8 (maybe other versions of IE but this is the one I'm testing on).

I am checking to see if the referrer of the site is not itself, and if not, delete all cookies with the cookie domain.

if ($_COOKIE['exp_last_visit'] < mktime("23", "59", "59", "12", "03", "2010")) {
if (!strstr($_SERVER['HTTP_REFERER'], $_SERVER['HTTP_HOST'])) {
foreach ($_COOKIE as $key => $value) {
setcookie($key, $value, time()-10000, "/", ".domain.com");
}
}
}

This works in Chrome and FF, but of course, not IE8.
If anyone could shed any light on this I'd be really grateful!

Hey guy's i have a script i did a few months ago and now noticed that it is doing its job but keeps the old file ..so i got the image a few times but on a different angle...

 

how can i optimize this code to delete the old image when doing the rotation?

 

<?php
session_start();
include_once 'dbconnect.php';
if (!isset($_SESSION['userSession'])) {
	header("Location: index.php");
}

$degrees = -270;
$path = $_GET['Folder'];
$file =$_GET['Pic'];
$fileid =$_GET['id'];

$image = $path.'/'.$file;
$imageN = $path.'/New_'.$file;
//load the image
$source = imagecreatefromjpeg($image);

//rotate the image
$rotate = imagerotate($source, $degrees, 0);

$NewImg='New_'.$file ;

//set the Content type
//header('Content-type: image/jpeg');

//display the rotated image on the browser
//imagejpeg($rotate);
imagejpeg($rotate,$imageN,100);
//free the memory
imagedestroy($source);
imagedestroy($rotate);
$sql = "UPDATE Coupon_list SET product_image_thumb = '$NewImg' WHERE id = '$fileid'";

if (mysqli_query($DBcon, $sql)) {
   echo "Rotation ok";
echo('<script language="Javascript">opener.window.location.reload(false); window.close();</script>');

} else {
   echo "Error Rotating: " . mysqli_error($DBcon);
}
mysqli_close($DBcon);
?>

I am using a WordPress theme that uses some of its own functions besides WP functions.

Let me make clear from the start that when I say "Multiple Checkboxes" in the paragraphs below I am NOT talking about checkboxes that each hold a single value.  I am talking about one Checkbox field that allows multiple values to be selected and puts those values into an array with one Name value and stores the output in a string in a single mysql table field.

Right up front, what I need during the Edit Ad functions is the inbuilt function that will Delete the previous Array of values in any multiple checkbox when the ad is updated. Right now updating the ad works for every situation except NO values selected or for Unchecking all previously selected values in a Multiple Checkbox.  If I have, for example, 4 checkboxes selected and unselect all of them before submitting the edited ad it will return the last saved array of values but not an Empty array with no checkboxes selected.

This theme has a Form Builder with a Custom fields builder used by the admin to create forms for a classified ads website. According to which category of ad the Ad creation procedure will show different forms, with different fields.

I had to manually create the capability to generate multiple checkboxes...so that the different multiple checkboxes when selected and updated to the mysql table might hold a variety of values in a comma-delimited array. That works fine.

When the Ad is edited on its own page, (outside of the Wordpress admin dashboard) the problem is that if a user would uncheck all checkboxes in a particular multiple checkbox then the unselected state does not overwrite the previous array of values. What returns after editing is the previous selected values.

I have tried jquery functions but none of them are working the way I had hoped.

so one type of checkbox might have a hypothetical value like this  "name="cp_checkbox_help[]" and if three options are selected then on submit the value could be--- name="cp_checkbox_help[Sunday,Monday,Tuesday]"

I use implode and explode to store the array as comma separated and retrieve the array for editing or display.

I guess I need to create a Null or empty value as a default that only changes when selections are made.

But, since I use implode and explode to make the array "pretty" I don't know if simply specifying nothing will erase a whole array on update.

Here is some of the code used to see how I get what I get--

This displays the checkboxes that I create and name and fill with different values--


case 'checkbox':
 ?>
<?php 
$options = explode(',', $result->field_values);
 echo '<div id="checkboxes"><table width="100%" border="0" cellspacing="0" cellpadding="5">
  <tr>
    <th colspan="2" scope="col">' . $result->field_label. '</th>
  </tr>';
$myvals= explode(',', $post_meta_val);
foreach ($options as $option) {
 {
 ?> 
              
              <tr>
    <td width="4%"><input style="display:inline-block; float:left;" type="<?php echo $result->field_type; ?>" name="<?php echo $result->field_name; ?>[]" class="checkbox<?php if($result->field_req) echo ' required'?>" id="<?php echo $field_label; ?>" value="<?php echo $option; ?>" <?php foreach ($myvals as $myval)
{ if (in_array($myval, array($option), true)) {echo 'checked="yes"';}}?>/></td>
    <td width="96%"style="vertical-align:top; text-indent: 7px; text-align: left;" ><?php echo $option . '</td>
  </tr> ' ?>   



<?php
             }     } echo '  </tr>
</table></div><div class="clr"></div>';
 break; 



Following is the main part of the code that updates the Ad form--



  // update the ad and return the ad id
    $post_id = wp_update_post($update_ad);



    if($post_id) {

        // now update all the custom fields
        foreach($_POST as $meta_key => $meta_value) {
            if (cp_str_starts_with($meta_key, 'cp_'))
if (cp_str_starts_with($meta_key, 'cp_checkbox_charley'))
$meta_value= implode(',', $_POST['cp_checkbox_charley']);
if (cp_str_starts_with($meta_key, 'cp_checkbox_help'))
$meta_value = implode(',', $_POST['cp_checkbox_help']);
if (cp_str_starts_with($meta_key, 'cp_checkbox_hello'))
$meta_value= implode(',', $_POST['cp_checkbox_hello']);
                //echo $meta_key . ' <--metakey <br/>' . $meta_value . ' <--metavalue<br/><br/>'; // for debugging
                update_post_meta($post_id, $meta_key, $meta_value);
        }

        $errmsg = '<div class="box-yellow"><b>' . __('Your ad has been successfully updated.','cp') . '</b> <a href="' . CP_DASHBOARD_URL . '">' . __('Return to my dashboard','cp') . '</a></div>';

    } else {
        // the ad wasn't updated so throw an error
        $errmsg = '<div class="box-red"><b>' . __('There was an error trying to update your ad.','cp') . '</b></div>';

    }

    return $errmsg;

}

Back on the Edit Ad page this is the Submit


                        <p class="submit center">
                            <input type="button" class="btn_orange" onclick="window.location.href='<?php echo CP_DASHBOARD_URL ?>'" value="<?php _e('Cancel', 'cp')?>" />&nbsp;&nbsp;
                            <input type="submit" class="btn_orange" value="<?php _e('Update Ad &raquo;','cp') ?>" name="submit" />

I have a feeling what I need is just a couple of lines to detect no posted values and then... but if one checkbox array has 6 values in it and another checkbox array has only 3 values, for example, do I need to count each specific checkbox for number of values and then overwrite or will one function completely delete the previous array and its commas?

I would really appreciate some expert assistance here!

I have a class I use to handle my various DB objects.  I want to close any connections, if needed, in my destructor.  I want to do this even though I already know the connection has been closed previously.  What I am looking for is a way to test the $connection variable I have to see if it's in need of closing.  I can't figure out how to do this.


if (isset($this->connection))
{
    echo "is set";
}
   
if ($this->connection)
{
    echo "here";
}


The above would output "is set" and "here", because in both tests say the already closed connection is still there.  Can anyone offer any help?

i have a script that wrote which updates fields in a mysql database with millions of rows. it just uses a while loop for each row.

now the problem is that i forgot to add something to the script, but i already visited the .php file in my browser.

i closed the browser and when i refresh the database it still seems to be running even though i closed the browser the script was running on....

is this because the script is still cached in the memory or what? how can i stop it?
