PHP - Manual Php Session Timeout?

When a user logs on, I authenticate them with a session.  How do I use php to determine the time until the session will expire?  I realize I could go into the ini file but is there a php code that can query this info and echo it back?

I have a form that is very long.  Sometimes the logged-in user will spend over 20 minutes on this screen and then when they hit submit, the session has already expired and they are redirected to the login screen and anything on that form is lost.
Is there a way to reset the session timeout to zero everytime they either click the screen with the mouse, or type something into a form field (without submitting the form)?  Not sure if this would only work with javascript or if there is php code that I would put in the beginning of the action.php that looks for whether the session has timed out and if so, add the form contents to the database first before logging them out?  A php solution like that would be preferable to a javascript one.
But also if the sessiopn has already expired, then the action.php script would be less secure if I put the code there because then anyone not logged in could use that page so that's probably not the solution.  Best solution would be to reset the session timer whenever they click ont he screen or start typing in the form.

Hello All,

I have a PHP web application which will refresh itself(ajax calls connecting to the server and get the latest data) periodically. These also update the Database-based session handler class. i.e. There is NO UPDATE to the session data but the timestamp is constantly updated.


Our problem is that garbage collection does not kick in as it looks at the difference between timestamp and session_gc.maxlifetime. So, if  and the user is not interacting with the application.

Now my question is how can I force the timeout even though refreshing happens but the user is not interacting with the application and there are "phantom" session updates made by these ajax calls.

Please let me know. Thanks.

hi
i am reading about sessions in the php manual.
what does this mean:
If register_globals is disabled, only members of the global associative array $_SESSION can be registered as session variables. The restored session variables will only be available in the array $_SESSION.
?

Where in the PHP manual can I find information about input validation? I looked and I seem to not find it.

I am intending to create my own email input validation.

Hello all,

My knowledge in PHP is growing everyday as I try out more stuff but I really didn't understand this bit :
"Note: Please note that the ternary operator is a statement, and that it doesn't evaluate to a variable, but to the result of a statement. This is important to know if you want to return a variable by reference. The statement return $var == 42 ? $a : $b; in a return-by-reference function will therefore not work and a warning is issued in later PHP versions. ".

taken from the page : http://www.php.net/manual/en/language.operators.comparison.php

From what I understood, if I was to use a ternery condition in the return statement, and return a referenced variable as a result, it
shouldn't work?

So this shouldn't work?

$int = 10;

function testReturn(&$referencedVariable) {
return (1==1) ? $referencedVariable : FALSE;
}

echo testReturn($int);


But it does. Anyways i'm pretty sure I didn't understand this right, so help with this is really appreciated

Hello forum.
I'm new here, but I've been reading and finding useful things for a while now.

I'm still new to PHP and I need a little help.

I'm doing a school project and I have some things I want to do, but do not know how to write it down in PHP.

I think I'll ask a lot of questions this week, and I hope I will get some help..

For start I want to ask this:

I've been using Code: [Select]
mysql_fetch_array() for doing loops and populating check-boxes. And everything's working fine.. but what I want is to control the actual loop by clicking buttons. Let's say first time a while-do is run, my check-boxes get populated from the database and every other loop the next data from the table is added.. pretty straightforward.
I want to be able to populate once, then click "next" and the new data to be added and so on..
Code: [Select]
<?php
$tema = mysql_query("SELECT * from questions")or die(mysql_error());

function answer1($string)
{
$string1 = explode("/", $string);
echo $string1[0];
}
function answer2($string)
{
$string1 = explode("/", $string);
echo $string1[1];
}

while ($row=mysql_fetch_array($tema))
{
echo mysql_fetch_array($tema);
$tip=$row["tip"];
if ($tip==2)
{
$id=$row['prasanje_id'];
$question=$row['question'];
$answer=$row['answer'];
?>
   <label> <?php echo $question?></label><br>
   <input type="checkbox"  name="CheckboxGroup1" value="checkbox" id="CheckboxGroup1_0" />
      <?php answer1($tekst) ?></label>
    <label>
      <input type="checkbox"  name="CheckboxGroup1" value="checkbox" id="CheckboxGroup1_1" />
      <?php answer2($tekst) ?></label>
<?php
}
}
?>I want an alternative to the while-do loop..
Is it possible to do this?

Thanks!!

Hello,
I have a wordpress site using Thesis 2.1 theme and I am displaying "excerpts" for each post on homepage.. I don't want to add <!-- more --> to each post and I want to show sth different, sth more valuable on the homepage to my readers.. Thats why I use excerpts.

I added this line of code to my custom.php file:

function new_excerpt_more($more) {
global $post;
return ' <a href="'. get_permalink($post->ID) . '">Continue Reading...</a>';
}
add_filter('excerpt_more', 'new_excerpt_more');

It added a "continue reading.." link to the posts that I haven't yet defined excerpt.. So, If nothing is written on the excerpt area of that post, it shows some part of the post and adds a "continue reading.." link to it on the homepage. But if I have written sth in the excerpt area of the post, it does shows the excerpt, but doesn't add the "continue reading.." link at the end..
I will be happy if you may help me on this, this drives me nuts currently! [/size]

MERGED

So basically, what I am trying to do is, adding read more tag to custom excerpts which we define manually.
Here is another code I tried but had no luck again!

//* Changing excerpt more - only works where excerpt IS hand-crafted
function manual_excerpt_more( $excerpt ) {
	$excerpt_more = '';
	if( has_excerpt() ) {
    	$excerpt_more = '&nbsp;<a href="' . get_permalink() . '" rel="nofollow">[Read more]</a>';
	}
	return $excerpt . $excerpt_more;
}
add_filter( 'get_the_excerpt', 'manual_excerpt_more' );

Hello I have the following error:

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'FROM players WHERE ((NOT inactive_player) AND ((players.Player_Last_Name = 'p' at line 3

I think my error is in the statement below...


    Code: [Select]
echo "1";
$getNewPlayers =
"SELECT players.Player_number,
players.Player_name,
FROM players
WHERE ((NOT inactive_player)
AND ((players.Player_Last_Name = 'player_find%')))
ORDER BY player_name";
$rsNewPlayers = mysql_query($getNewPlayers, $link) or die (mysql_error());
$varNewCount = mysql_num_rows($rsNewPlayers);
echo $varNewCount['Player_name'];


Can you tell me where the error is and how I might go about to fix it?

Thanks,

Hi, I have been trying to make a page which shows a number of thumbnails, populated by images and text from a database, this I got working perfectly fine, but as I am now trying to make it so users can log in and edit or delete each one, it has all started to go a bit wrong and I was wondering if anyone could spot why?!?

It is currently bringing up this message on the screen:

I was looking at the manual:   http://php.net/manua....precedence.php   And I notice that the parenthesis () operator and print operator are missing from the list. Why so? I would like to know where these operators fall in the precedence and associativity chart.

$pastelink = "<br /><a href='view.php?paste=$lol&language=$language'>$name</a>";
mysql_query("INSERT INTO recent (url) VALUES ('$pastelink')");


That query won't run, however if I do this:


$test = $_POST['name'];
//$pastelink = "<br /><a href='view.php?paste=$lol&language=$language'>$name</a>";
mysql_query("INSERT INTO recent (url) VALUES ('$test')");


It will run, is this because of the single quotes in $pastelink?

& If so, how can I fix it?

I am trying to use this: http://php.net/manual/en/function.xml-parse-into-struct.php to parse this:

Code: [Select]
<?xml version="1.0" encoding="utf-8"?>
<PaymentNotification xmlns="http://">
  <PaymentMethod>card</PaymentMethod>
<Hash>12345KKLS</Hash>
<Payments>
    <Payment>
      <PaymentID>709750ba-b9b6-44c4-9812</PaymentID>
      <Amount>70</Amount>
      <Currency>USD</Currency>
      <Date>2011-05-11T07:41:44.957</Date>
      <StatusID>4</StatusID>
    </Payment>
    <Payment>
      <PaymentID>e0c66bae-c423-43c6-b896</PaymentID>
      <Amount>50</Amount>
      <Currency>USD</Currency>
      <Date>2011-05-11T07:42:13.55</Date>
      <StatusID>2</StatusID>
    </Payment>
  </Payments>
</PaymentNotification>

...but can't work out which numbers to use. I only need to grab the payment ID where the statusID is 4 (for each one as could be 1 or more per xml message).

It's very complicated http://php.net/manual/en/function.xml-parse-into-struct.php
