Newb Question On Php Sessions

Hi - I'm using SESSION variables to keep track of customers who come onto the site to order stuff. For example $_SESSION['customerid'] all the incoming customers.

I also use SESSION variables with a different value for the managers to look at and keep track of customer data. eg : $_SESSION['customer']['firstname']

I am expecting many customers and managers to be simultaneously using the site.

QUESTION: Do I need to increment the SESSION variable in some way in order to avoid that a session gets overwritten, or will my SESSION variables keep track and keep everything separated by dint of the fact that they contain different values ?

so far my testing shows that things are working correctly, but I can only test with 3 / 4 virtual users in different browser windows .

So I wrote this code, what its supposed to do is draw an image on a grid space, based on its X,Y coordinates from a mySql database, compared to the player X,Y. Heres the code:

Code: [Select]
<table>
<tr>
<td>
<?php
//northwest
echo "nw";
$x1 = $_SESSION[x] - 1;
$y1 = $_SESSION[y] + 1;
$hasobject1 = mysql_query("SELECT * FROM objects WHERE x='$x1' && y='$y1'");
while($row = mysql_fetch_array($hasobject1))
{
$image = "space_228.gif";
$image = $row[image];
}
if(!empty($image)){
echo "<IMG SRC=$image WIDTH=64 HEIGHT=64 onerror='onImgError(this)>'";
}
else{
echo "<IMG SRC='space_228.gif' WIDTH=64 HEIGHT=64>";
}
?></td>
<td><?php
//north
echo "n";
$x2 = $_SESSION[x];
$y2 = $_SESSION[y] + 1;
$hasobject2 = mysql_query("SELECT * FROM objects WHERE x='$x2' && y='$y2'");
while($row = mysql_fetch_array($hasobject2))
{
$image = "space_228.gif";
$image = $row[image];
}
if(!empty($image)){
echo "<IMG SRC=$image WIDTH=64 HEIGHT=64 onerror='onImgError(this)>'";
}
else{
echo "<IMG SRC='space_228.gif' WIDTH=64 HEIGHT=64>";
}
?></td>
<td><?php
//northeast
echo "ne";
$x3 = $_SESSION[x] + 1;
$y3 = $_SESSION[y] + 1;
$hasobject3 = mysql_query("SELECT * FROM objects WHERE x='$x3' && y='$y3'");
while($row = mysql_fetch_array($hasobject3))
{
$image = "space_228.gif";
$image = $row[image];
}
if(!empty($image)){
echo "<IMG SRC=$image WIDTH=64 HEIGHT=64 onerror='onImgError(this)>'";
}
else{
echo "<IMG SRC='space_228.gif' WIDTH=64 HEIGHT=64>";
}
?></td>
</tr>
<tr>
<td><?php
//wesr
echo "w";
$x4 = $_SESSION[x] - 1;
$y4 = $_SESSION[y];
$hasobject4 = mysql_query("SELECT * FROM objects WHERE x='$x4' && y='$y4'");
while($row = mysql_fetch_array($hasobject4))
{
$image = "space_228.gif";
$image = $row[image];
}
if(!empty($image)){
echo "<IMG SRC=$image WIDTH=64 HEIGHT=64 onerror='onImgError(this)>'";
}
else{
echo "<IMG SRC='space_228.gif' WIDTH=64 HEIGHT=64>";
}
?></td>
<td><?php
echo "p";
//player
echo "<IMG SRC='spaceship_wire5.jpg' WIDTH=64 HEIGHT=64>";
?></td>
<td><?php
//east
echo "e";
$x5 = $_SESSION[x] + 1;
$y5 = $_SESSION[y];
$hasobject5 = mysql_query("SELECT * FROM objects WHERE x='$x5' && y='$y5'");
while($row = mysql_fetch_array($hasobject5))
{
$image = "space_228.gif";
$image = $row[image];
}
if(!empty($image)){
echo "<IMG SRC=$image WIDTH=64 HEIGHT=64 onerror='onImgError(this)>'";
}
else{
echo "<IMG SRC='space_228.gif' WIDTH=64 HEIGHT=64>";
}
?></td>
</tr>
<tr>
<td><?php
//southwest
echo "sw";
$x6 = $_SESSION[x] - 1;
$y6 = $_SESSION[y] - 1;
$hasobject6 = mysql_query("SELECT * FROM objects WHERE x='$x6' && y='$y6'");
while($row = mysql_fetch_array($hasobject6))
{
$image = "space_228.gif";
$image = $row[image];
}
if(!empty($image)){
echo "<IMG SRC=$image WIDTH=64 HEIGHT=64 onerror='onImgError(this)>'";
}
else{
echo "<IMG SRC='space_228.gif' WIDTH=64 HEIGHT=64>";
}
?></td>
<td><?php
//south
echo "s";
$x7 = $_SESSION[x];
$y7 = $_SESSION[y] - 1;
$hasobject7 = mysql_query("SELECT * FROM objects WHERE x='$x7' && y='$y7'");
while($row = mysql_fetch_array($hasobject7))
{
$image = "space_228.gif";
$image = $row[image];
}
if(!empty($image)){
echo "<IMG SRC=$image WIDTH=64 HEIGHT=64 onerror='onImgError(this)>'";
}
else{
echo "<IMG SRC='space_228.gif' WIDTH=64 HEIGHT=64>";
}
?></td>
<td><?php
//southeast
echo "se";
$x8 = $_SESSION[x] + 1;
$y8 = $_SESSION[y] - 1;
$hasobject8 = mysql_query("SELECT * FROM objects WHERE x='$x8' && y='$y8'");
while($row = mysql_fetch_array($hasobject8))
{
$image = "space_228.gif";
$image = $row[image];
}
if(!empty($image)){
echo "<IMG SRC=$image WIDTH=64 HEIGHT=64 onerror='onImgError(this)>'";
}
else{
echo "<IMG SRC='space_228.gif' WIDTH=64 HEIGHT=64>";
}
?></td>
</tr>
</table> Now what happens is it draws the image on a bunch of different spots. The object is at 0,0. It doesnt display the object if the object is out of range of the player, or the player is at 0,0. But if the player is near the object, it draws it on like half the grid spaces, and on some places everywhere but the players.

Session Hell

Similar Tutorials

Short version of my question is going to be "why are my session variables vanishing?"

[ START not important Stuff ]

My (simplified) site layout looks like login_page.php ->page1.php->page2.php
login_page.php connects to mysql, to check login/pwd, and, if valid, sets the _SESSION id's/other credentials and then redirects to page1.php. page1.php has link to page2.php. Both page1 and page2 check against (require_once) an auth.php (authorization) and redirect to login_page.php if not logged in.
The auth.php file has the structu

session_start();
if(!isset($_SESSION['SESS_USER_ID'])|| other parameters){
//code
}

page2 has an AJAX load that pulls in a php file that includes various content (XML,text,.htm,etc.) That php file also requires auth.php

All of these things work.

[ END not important stuff ]

[Start important part]
Everything works. Session variables persist and are readable/accessible via all pages, as well as a Debug link (pop window that echos the $_SESSION vars.)
UNLESSS the user is inactive for more than a minute or two; At which point the session variables vanish.

Again, I can log in, Set the session variables, load multiple pages via AJAX (all of which are checked against the session variables...which means they have to exist) and generally everything works as expected. However, if I stop navigating/interacting with the site for more than a minute, or so, the session variables vanish (user id / other user credentials) and the I'm kicked back to the login the next time I click a link.

There is nothing but the initial mysql login that writes to the session variables. No code, on any other page, does anything but read the session.

My php ini file appears to have the correct location for my session.save_path.
The garbage collection is the defualt 1440
and the cache_expire is also the default 180

I'm hosted with fatcow (starting to regret that) with Debian/Apache/php5

Oh and, this happens on every browser on Linux, Mac, and Windows. But it doesn't seem to occur if I run it locally from xampp/lampp.

I'm at a total loss as to ideas for my next debugging step and any suggestions would be much appreciated.

Having A Hell Of A Time With Arrays - Need Some Help Please.

Ok, I will explain first what I am trying to do, and show you how I am going about it, which isn't working

I have a table set up. It has missing ID numbers, such as, 1 2 3 6 7 8 11 12 ..etc.

I am trying to pull a random ID number from all valid ID numbers. (Meaning, I don't want to get an ID of a record that is no longer there, so skip all the missing ID's)

This is for a cron job to change which record is being shown each day, randomly. I figured, logically, the best way to do this would be to pull all the valid ID's into an array, and then use array_rand($id_array,1); to pull one random ID number out of the array.

So, I tried using this code:
Code: [Select]
//Set variable as an array
$id_array = array();

//Populate array with valid ID's
$sql="SELECT ID FROM riddles";
$result=mysql_query($sql,$db) or die(mysql_error());
while($row = mysql_fetch_array($result,$db))
{
$id_array[] = $row['ID'];
};
print_r(array($id_array));

$new_rotd=(array_rand($id_array[0],1));

I am running into 2 problems with this code. First, when I print_r the array, I get the following:

Quote

Array ( => Array ( => [1] => [2] => [3] => [4] => [5] => [6] => [7] => [8] => [9] => [10] => [11] => [12] => [13] => [14] => [15] => [16] => [17] => [18] => [19] => [20] => [21] => [22] => [23] => ) )

The numbers are not correct. It is the correct number of total records, but it is not putting the correct ID number in there.

2) When I try and pull a random number out of the array, I get an error saying the First argument has to be an array. It IS an array?!

I need to get this working, so any help would be much appreciated. To summarize I need to:
Pull all valid ID #'s out of the table and put them in an array. Pull one random number out of that array and set it as variable: $new_rotd

I need to rewrite this php statement

When I try to do this

Hi All,

Im modifying someone elses PHP code (survey tool) (and i havent done PHP for years) Basically the code exports to an external csv file to a file called export.csv
However everytime i get it to export, it creates copies. ie it will export to export(2).csv and export(3).csv.

How can i make it so that it exports and overwritesa/ammed the existing export.csv file?

I had a look at the code and i believe this code below is doing the exporting but not sure

code doing the export ( i think)

Code: [Select]
<?php

include('classes/main.class.php');
include('classes/special_results.class.php');

$survey = new UCCASS_Special_Results;

echo $survey->results_csv(@$_REQUEST['sid'],$_REQUEST['export_type']);

?>
The class that it uses to export

Code: [Select]

Newb Preg_match Problem

Similar Tutorials

Hi, preg_match isn't working the way I feel it should.

The idea, when i finally get this script working, is to echo an order form back to the client (so they can see what they've ordered). At the moment I'm just trying to get the product description for each ordered product.

$aryOrder:
prodCode[6722] with a value of (for instance) 2
prodCode[6724] with a value of (for instance) 1
etc
(only ordered products present in the array)

prodDB.txt
6722 Hydrocolloid Blister Care
6724 Toe Spreader
etc
All products present in text file (prode code Description)

BUT I get an echo with no matches for any ordered product (or any prod for that matter) i.e.
no match: 6724, 6724 TOE SPREADER
when clearly, the product code (6724 $aryItem) is present in the text file line ($line_of_text).

I just don't get it!

foreach($aryOrder as $aryItem => $qty) {
     $file_handle = fopen("prodDB.txt", "r");
     while (!feof($file_handle)) {
     $line_of_text = fgets($file_handle);
     if (preg_match($aryItem, $line_of_text))
     {
     echo "Matched! $aryItem, $line_of_text QTY: $qty <br>";
      }
      else
      {
      echo "no match: $aryItem, $line_of_text <br>";
     }
     }
     fclose($file_handle);
}

I'm completely new to PHP, trying to work it out from the manual, so I've probably made a very basic mistake, and may even be going about this in entirely the wrong way.
Any help much appreciated,
Steve

Newb: Post (?) To A Remote-url Form Help.

Similar Tutorials

A couple months back, I asked on a gaming forum if anyone knew of a website that would track your *Steam Wishlist and email you when one of your wishlist games went on sale.
No one at the time knew of a **solution, so I decided to buy "PHP, MySQL and Javascript" and try to roll my own.

I managed to get the basics working.

After the basics, I started thinking about fun stuff I could do with the data I collected from Steam regarding the games that go on sale regularly.
The first part of my code file_get_content's the ***sale page(s) of games, and sucks out the games name, regular price, sale price, and the games homepage URL on Steam.
This is enough to accomplish my basic task.

The second part is where I need help, and that's getting more details on the game.

The additional details I want to get about the game include its Publisher and Developer, and to get that detail I need to go to the games homepage URL I previously got from the global sale page.

The issue is this: Some games have an age-restriction limitation, and you have to fill out a date form before entering the games homepage.
An example of one of those pages would be: http://store.steampowered.com/agecheck/app/1250/

I want to be able to POST a legal age to the above URL, and then (this is where I'm hazy) "re-load" the same URL, authorized by my previous POST.
Is that possible?

* Steam is a digital download service for computer games.
** Subsequently, there was another website found. But I was well into developing my solution and having fun.
*** Example: http://store.steampowered.com/search/?specials=1

Php Newb: How Can I Get Absolute Path For Images?

Similar Tutorials

I'm working on an email template system where my client will go to a page and copy & paste the source code into their crm system.

I'm trying to find a way to automatically replace the image path without the use of echo if possible.

I've figured this out already with this script:

Code: [Select]
<?
function GetFileDir($php_self){
$filename = explode("/", $php_self); // THIS WILL BREAK DOWN THE PATH INTO AN ARRAY
for( $i = 0; $i < (count($filename) - 1); ++$i ) {
$filename2 .= $filename[$i].'/';
}
return $filename2;
}
?>
But I don't wanna have to go in and put Code: [Select]
<?php echo GetFileDir("http://".$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI']); ?> before all the image paths.

So basically anywhere that src="images/whatever.jpg" is listed it will replace "images/" with "http://www.mydomain.com/images/whatever.jpg"

is it possible to do this without having to place code before "images" ?

Json Newb... Can't Parse This String

Similar Tutorials

I'm trying the fetch some geocode data from mapquest. Google doesn't like me right now. I keep running into the query_limit. So I want to set a back up that will go into production when I get that error from the big G.

I have my api key and I can put the string in a var.
Code: [Select]
$geocode = file_get_contents($url)

I selected json as the output and when I echo $geocode... here is the first portion of the string....(I want lat & lng)

Code: [Select]
renderOptions({"results":[{"locations":[{"latLng":{"lng":-112.35984,"lat":34.58752},.....
Now for the life of me, I can't do anything with it.
I've tried json_decode() with the true argument there and not.
Code: [Select]
$output = json_decode($geocode, true);
$output = json_decode($geocode);
vardump($output) is NULL.

So, I thought, well maybe I don't need to decode it, but I can't figure out how to parse it.

I'm lost. This admittedly is my first attempt as trying to work with a jason object, but jeesh, it doesn't seem like it should be that hard.
Can someone start me in the right direction?

Newb: Table Merge Issues

Hi there,

I'm new to this (2 days into it) but I've managed to rummage together 2 tables, and PHP to input into the database. My issue now is that I want to merge one of the two tables into the other. I've managed to do this, but for some reason I'm getting duplicate entries from the 2nd table.

Code:
//mysql connection

$query = "SELECT ArticleDescription, URL FROM top_web_articles"or die ("query is messed up");

   $result = mysql_query($query);
   while ($line = mysql_fetch_array($result, MYSQL_ASSOC)) {

mysql_query("INSERT INTO web_articles (ArticleDescription, URL) SELECT ArticleDescription, URL FROM top_web_articles") or die ("Failed merge!");
}
echo ("Successful merge!");
?>

Does anyone have any suggestions as to where I went wrong?

Thanks in advance,
