PHP - This Is Wierd Scripted Is 100% Rigth Buth Output Not

Hi Everyone

I have a weird session issue going on and i'm not sure what is causing it.

Basically any sessions that i set are randomly expiring sooner than they should be. As a test I did the following:

Code: [Select]
<?php
session_start();
if(isset($_SESSION['views'])){
    $_SESSION['views'] = $_SESSION['views']+ 1;
}else{
    $_SESSION['views'] = 1;
}
echo "views = ". $_SESSION['views'];
echo '<p><a href="testpage.php">Refresh</a></p>';

?>

If i continue to click the refresh button, i sometimes get to 30 and then it starts at 1 again. Other times ill get to 20 and then back to 1. It has also sometimes skips a couple of counts from 7 to 11 as an example in one click.

Any one come across this before?

I have been reading up online and some have mentioned PHP upgrades from php4 to php5 cause some issues and specifically the hosting company changing the session.save_path.

If this was the case, it wouldn't even count to 10, would it?

Any help would be really appreciated.

thanks in advance

I'm using WampServer to test php pages locally.  I just started having this warning message show up:

Warning: session_start() [function.session-start]: open(c:/wamp/tmp\sess_3c3f4g0dhb6qu007v167pv1u45, O_RDWR) failed: Permission denied (13) in C:\wamp\www\page_include\index.inc.php on line 2

The warning shows up and I am directed to the login page.  The funny thing is, when I refresh the browser, the warning goes away and the page is directed to the page the user is directed to after they are signed in.  I haven't changed any of my code since everything was working fine.  Is this a problem with WampServer or possibly something that I should be looking at changing my code to fix?  Any suggestions?  Thanks.

Hello All,   I'm kinda new to PHP and web development and I seem to have a very wierd problem which is driving me nuts (for the last 2 days)...so I'd appreciate any and all help in getting it resolved.   Okay, so here's the problem:   In the code below, I used to have just the first statement below...which essentially accepted input as a textbox for a text field named qty_pkg (in the underlying MySQL table)...and that used to work just fine.   So then I decided to change the input type for that field to be a radio button, accepting one of two choices i.e. "UoM" or "Qty", and therefore I added the remainder of the code, whilst also commenting/remarking out the first statement.   What happens (when I added the radiobutton-related code) is that control no longer goes into the TRUE portion/logic of the "if ( !empty($_POST))" condition-check, but rather, it seems to go into the "ELSE/FALSE" portion of that conditional check. However, a record does get added to my table, even though I do not have an "INSERT INTO..." clause in the ELSE porition of that check. Also, what gets displayed on screen is as follows: ------------------------------------------------------------------------------------------------------------------------------------ Array() There's something wrong somewhere!!! Array() ------------------------------------------------------------------------------------------------------------------------------------   Now, if/when I comment/remark the radiobutton-related code, the "if ( !empty($_POST))" logic seems to work fine and the following is displayed on screen (which is what I expect): ------------------------------------------------------------------------------------------------------------------------------------ Array ( [datepicker] => 10/30/2014 [store_id] => 48 [new_store_name] => [item_id] => 5 [new_item_name] => [pkg_of] => 1 [price] => 1 [flyer_page] => 1 [limited_time_sale] => Array ( [0] => fri [1] => sat ) [nos_to_purchase] => 1 [create-and-add-more] => Create and Add More )
Notice: Undefined index: qty_pkg in /var/www/create.php on line 54
Array ( [0] => Array ( [item_id] => 5 [0] => 5 [item_name] => BD Cheese Strings [1] => BD Cheese Strings [section_id] => 7 [2] => 7 ) ) ------------------------------------------------------------------------------------------------------------------------------------   The other wierd thing is that if/when I now uncomment the first statement (which used to work just fine before) the "if ( !empty($_POST))" logic no longer seems to work the way it used to.   Does/can someone see something wrong with my code somewhere?

Well I have a script that executes a scan on a system set to run infinitely, and I need it to echo out a message each time it loops through, but I don't want it to echo out the message with the next loop message below it, and the next one below that etc... I've tried using the flush(); function and been messing around with that with no luck. For security reasons I don't want to release any of the processing code, but here is the basic construction of the script:

<?PHP
***PROCESSING AND SCAN CODE***
***PROCESSING AND SCAN CODE***
***PROCESSING AND SCAN CODE***
***PROCESSING AND SCAN CODE***
$RepeatIt = -1;
for($g=1; $g!=$RepeatIt+1; $g++)
{
***PROCESSING AND SCAN CODE***
***PROCESSING AND SCAN CODE***
***PROCESSING AND SCAN CODE***
***PROCESSING AND SCAN CODE***

$ScanMessage = ":.:.: SCANNING THE HITLIST FOR MOBSTER: ".$MobName." (SCAN #$g) :.:.:"."<br/><br/>";
echo $ScanMessage;

***PROCESSING AND SCAN CODE***
***PROCESSING AND SCAN CODE***
***PROCESSING AND SCAN CODE***
***PROCESSING AND SCAN CODE***
}
?>

At the moment it's returning:

:.:.: SCANNING THE HITLIST FOR MOBSTER: DEUS EX DESTROYER (SCAN #1) :.:.:

:.:.: SCANNING THE HITLIST FOR MOBSTER: DEUS EX DESTROYER (SCAN #2) :.:.:

:.:.: SCANNING THE HITLIST FOR MOBSTER: DEUS EX DESTROYER (SCAN #3) :.:.:

:.:.: SCANNING THE HITLIST FOR MOBSTER: DEUS EX DESTROYER (SCAN #4) :.:.:

So what I want it to do is just delete the scanning message and replace it with the next scan message so while running this script you would see just the number increment on the same line.

Any suggestions?

Thanks.

Hi all,

Is there a simple way to log the command output of a linux console?

This command locks up my screen. It is a screen on an Aastra IP phone.

$command = 'logsave /var/www/html/aastra/test.log ls';

shell_exec($command);


Thanks!

I have created a PHP page where the contents are pulled from DB. Is there a way that I can save the file with the output and stylesheet to PDF with a click of a button.

Hey folks,

I have made a cart for buying drinks. I also made an sql database. But when I click on the email button, I receive an email but only with the id of the products. I would like to have an output with the id of the product, but also the name of the product ( the name of the column in sql is also 'name')

this is my code and you can check it out on  http://fhcs.be/cart-demo3/

Hi. I found a code online but unfortunately, the data is retrieved via variables. How can i convert this code to retrieve the data from database instead. Thank you in ADVANCE!

Code: [Select]
var members = [
    ['Steven B. Ayres', '1911-1913', 'New York', 'Independent Democrat', '1861-1929'],
    ['William Augustus Ayres', '1915-1921 1923-1934', 'Kansas', 'Democratic', '1867-1952'],
    ['William Hanes Ayres', '1951-1971', 'Ohio', 'Republican', '1916-2000']
];

help me.
i have an index.php file in admin folder.
this is the code inside the file:
Code: [Select]
<?php
?>

Or any other code
and i get output 0 ,
but if i echo something else then i get the string has output,

help find out what is the problam please!!!

I'm not getting any errors but I"m not getting the output I'm expecting. When it gets the characterIDList values if there is a value for that field it needs to take that value then explode it and get the ID and characterName of each of the values so say the value inside of characterIDList was 2,3 then for each of those values it would find the characterName and ID of the value and be able to put each of them as a LI inside the UL.  I was hoping I could have the charactersQuery separate because I use it for the dropdown.

Code: [Select]
$newsQuery = "

        news.categoryID,
        news.newsTitle,
        news.newsPicture,

        LEFT JOIN categories
            ON news.categoryID = categories.ID

$newsResult = mysqli_query ( $dbc, $newsQuery ); // Run The Query
echo $newsQuery;
$row = mysqli_fetch_array ( $newsResult, MYSQL_ASSOC );
$characterIDList = $row[ 'chracterIDList' ];

$characterIDList = explode(',',  $characterIDList);
