PHP - Browser And $_session Data Now I Remember It Now I Don't Behavior

Hi folks,

I have an initial redirect page which directs to my main page, sending two reference variables as $_GET parameters:

Code: [Select]
header("Location: /ob/index.php?id=".$id."&ref=".$ref);
The first thing this main page does is include a file which checks for those two values:

Code: [Select]
if (substr_count($_SERVER['HTTP_ACCEPT_ENCODING'], 'gzip')) ob_start("ob_gzhandler"); else ob_start();
session_start();
error_reporting(E_ALL);

if (isset($_GET['id']) && isset($_GET['ref'])){
$_SESSION['id'] = $_GET['id'];
$_SESSION['ref'] = $_GET['ref'];
}
if(!isset($_SESSION['id']) || $_SESSION['id']=="" || !isset($_SESSION['ref']) || $_SESSION['ref']==""){
echo ("This service requires a valid ID to run - your session may have expired, please refresh your browser to try again.");
exit;
}
The main page loads fine - meaning that the $_SESSION variables have been set correctly. However, when the next page loads (including the same file), the $_GET values obviously aren't there but the $_SESSION variables should be intact. I am getting fails every time though in Opera and Safari (have checked in IE, FF and Chrome and all seems well).

However, if I then refresh the browser - in both Opera and Safari - the next page loads fine and the $_SESSION variables are correctly set.

Any ideas on this at all?

Many thanks in advance,

Rich

hey gang:

i have a number of variables stored in the $_SESSION array and wanted to know how i can keep them handy for use AFTER PayPal has done it's thing.  to help clarify, the desired process here is client fills out form. clicks PayPal button. form data is then used to create some documents which are then sent to client.  i have the flow working but without the PayPal part because i'm not sure how to preserve the form data while PayPal does it's thing so i can use it when PayPal is done.  am i making sense?  i'd like to steer away from client-side cookies because of security issues and our paranoid client insists on it...

bah.  first the JSON shuffle from JavaScript to PHP and now this PayPal mess. 

any help is MOST welcome.  TIA!

WR!

The below should choose the radio button that is set by the $_SESSION variable or default to 3. However, it's defaulting to 1.

Code: [Select]
$content.='
<p class="form_item"><label>Product Rating:</label><br />
<div class="rating_radio"><input type="radio" name="review_product_rating" value="1"';
if(isset($review_product_rating) && $review_product_rating=="1"){$content.='checked';}
$content.=' /> <br />1</div>
<div class="rating_radio"><input type="radio" name="review_product_rating" value="2"';
if(isset($review_product_rating) && $review_product_rating=="2"){$content.='checked';}
$content.=' /> <br />2</div>
<div class="rating_radio"><input type="radio" name="review_product_rating" value="3"';
if(isset($review_product_rating) && $review_product_rating=="3" || !isset($review_product_rating)){$content.='checked';}
$content.=' /> <br />3</div>
<div class="rating_radio"><input type="radio" name="review_product_rating" value="4"';
if(isset($review_product_rating) && $review_product_rating=="4"){$content.='checked';}
$content.=' /> <br />4</div>
<div class="rating_radio"><input type="radio" name="review_product_rating" value="5"';
if(isset($review_product_rating) && $review_product_rating=="5"){$content.='checked';}
$content.=' /> <br />5</div>
<div class="worst">(Worst)</div><div class="best">(Best)</div>
</p>

I'm figuring it's because it's multiple if statement (with no elseif) so it's evaluating the first if and being set to true. I tried changing everything else after the first one to elseif, and it's throwing an unexpected T_ELSEIF error.

I'm trying to have a running total of the number of views an image gets. My test file works perfectly every time. The actual file, image_win.php, does not and after much testing can't see what's wrong. This files STRANGENESS: the first two views count fine, with 1 added the total in the field image_visit. But every time after that 2 is added to the total in image_visit. Very bizarre.

Thanks for taking a look -Allen
Code: [Select]
<?php
////////TEST IMAGE_WIN //////////THIS WORKS
include_once "scripts/connect_to_mysql.php";
include_once "scripts/paths.php";
$art_id = 372;
$QUERY="SELECT user_id FROM artWork WHERE art_id = '$art_id'";
$res = mysql_query($QUERY);
$num = mysql_num_rows($res);
if($num >0){

while($row = mysql_fetch_array($res)){ 
     $owner_id = $row['user_id'];
    }
}
mysql_query("UPDATE userInfo SET image_visit = image_visit +1  WHERE user_id = '$owner_id'"); 
?>

<?php 
//////// image_win.php  /////////THIS DOES NOT WORK
$user_id=$_SESSION['user_id'];
include_once "scripts/connect_to_mysql.php";
include_once "scripts/paths.php";

$art_id = $_GET['art_id'];

MOD EDIT: code tags added.

First let me explain my code.
It comprises of three php files.

inc_fn_header_and_menu.php,  contains the HTML and CSS header details and it initializes the session via session_start();

 

This  is later included in project_status.php] .

 

In project_status.php] , I have included another file project_status_app.php which contains a HTML form.

 project_status.php:

<?php
 include 'inc_fn_header_and_menu.php';
function includeFile($file,$variable) {
    $var = $variable;
    include($file);
}
if (isset($_GET['id']) && $_GET['id']!="") {
    $pid    = $_GET['id'];
    $_SESSION['pidForApproval'] = $_GET['id'];
    $query = 'SELECT * FROM `profile` WHERE pid ='.'\''.$pid.'\'';
    $result=mysqli_query($db,$queryToRetrievePP) or die("There are no records to display ... \n" . mysqli_error());
    foreach ($result as $row) {
        $status = $row['status'];
    }        
}
...........some PHP and HTML code.......
	<div id="customerPurchaseApprovalForm">
<?php  
  echo '<p>APPROVAL FOR CUSTOMER PURCHASE</p>';
  $discountApprovalStatus = "Granted";
  if ($discountApprovalStatus == "Granted") {  
 
  includeFile("project_status_app.php",$highestannualvalue);
  } else {
     //.........
  }

In project_status_app.php I am attempting to retrieve pidForApproval from the $_SESSION array.

<?php
        // put your code here  UPDATE `pp` SET `customer_purchase_remarks` = 'hahaha' WHERE `pp`.`id` = 207;
        
        if ($_SERVER['REQUEST_METHOD'] == 'POST') {
            include '../../inc/fastlogin.php';      
            $sql = "UPDATE pp SET customer_purchase_remarks ='{$_POST['remarkstxt']}' WHERE pp.pid='{$_SESSION['pidForApproval']}'"; 
            $result = mysqli_query ( $fastdb, $sql ) ;
            if (mysqli_affected_rows($fastdb) != 1) { 
               $_SESSION['err_cpa_rmks'] = "<p>Error while updating WHERE id='{$_SESSION['pidForApproval']}'</p>";
                //echo "<p>Error while updating WHERE id='{$_POST['pidForApproval']}'</p>".mysqli_error($fastdb);                 
            } else { 
                $_SESSION['suc_cpa_rmks'] = "<p>Records was updated successfully.</p>";
                //echo "Records was updated successfully."; 
            }
            header ("location: project_status.php?id="$_SESSION['pidForApproval']);
            exit();
        }    
        
        ?>

When I load  project_status.php,  project_status_app.php is supposed to display the form. Once the user fills in the form the and the submit button has been pressed, the UPDATE statement is supposed to run and then it is supposed to navigate back to project_status.php?id=FA142. But the update is failing and the when the project_status.php is loaded back, the url looks like this http://localhost/fast/project_status.php?id= . The id is empty. It is supposed to be something like this http://localhost/fast/project_status.php?id=FA142. With the id being populated at the 

header ("location: project_status.php?id=".$_SESSION['pidForApproval']);

I suspected that my $_SESSION['pidForApproval'] is not being populated in project_status.php but I echoed back $_SESSION['pidForApproval'] in that file itself and I can see it is being populated. Hence, I suspect that the $_SESSION['pidForApproval'] is not being passed to project_status_app.php. I have already attempted to include session_start(); clause in project_status_app.php but that gives an error, stating that the session has already started, in inc_fn_header_and_menu.php. Can someone help me as to why the $_SESSION['pidForApproval'] is not being passed on to the project_status_app.php file. Thank you.

Missing some information.

Hello everyone, I am working on a form that is similar to a shopping cart system and I am thinking of creating a button that submits the checked value and saves them to a $_SESSION variable. And also a link that links to a cart.html that takes the values of a $_SESSION variable. I am have trouble figuring what tag/attribute should I use in order to achieve that.   Right now my code attached below submits the checked values to cart.html directly. However I want my submit button to save the checked box to a $_SESSION variable and STAY on the same page. And then I will implement a <a> to link to the cart.php.   I researched a little bit about this subject and I know it's somewhat related to ajax/jquery. I just wanted to know more about it from you guys. I appreciate your attention for reading the post and Thanks!   Below is the form that I currently have:

<form name= "finalForm" method="POST" action="cart.php">
<input type="Submit" name="finalSelected"/>

<?php foreach($FinalName as $key => $item) {?>
<tr>
<td><input type="checkbox" name="fSelected[]" value="<?php echo htmlspecialchars($FinalID[$key])?>" />
<?php echo "$FinalID[$key] & $item";?>
</td>
</tr>
<?php } ;?>

Below is the code for cart.php

<?php
require ('connect_db.php');
if(isset($_POST['finalSelected']))
{
	if(!empty($_POST['fSelected']))
	{
		$chosen = $_POST['fSelected'];
		foreach ($chosen as $item)
			echo "aID selected: $item </br>";
		$delimit = implode(", ", $chosen);
		print_r($delimit);
	}

}
if(isset($delimit))
{
$cartSQL = "SELECT * from article where aID in ($delimit)";
$cartQuery = mysqli_query($dbc, $cartSQL) or die (mysqli_error($dbc));
while($row = mysqli_fetch_array($cartQuery, MYSQLI_BOTH))
{
	$aTitle[] = $row[ 'name' ];
}
}
?>

<table>
	
		<?php if(isset($delimit)) { 
		$c=0; foreach($aTitle as $item) {?>
		<tr>
		<td>
			<?php echo $aTitle[$c]; $c++;?>
		</td>
		</tr>
		<?php }}?>
</table>

not sure if this will find an answer but I am posting anyway. Any help is appreciated....my coder has left the team and no matter how I invite her to come and do some bug squashing, her new schedules won't fit a re-visit into my little aplication...I am eager to delve into the codes at my very low knowledge of php. I have initiated reading and is still trying to teach myself...but of course not as fast as the app needs the patch...here's the meat:

hi all,

does anyone know the name of the following
its a way to make a huge string than can have variables in it.

look a bit like this but couldnt remember the right syntax, nor the name so was kinda hard to look on google.

ABC>>>
   some stuff inside
ABC;

I want to save live data into file. My script fetch the data (one by one) and save it into file by amend method. The live data is not regular and every time it must be checked if the value has been updated or it is still the last value. One way to do so is to read the last line of the file and compare it with the fetched value. But in this case, I need to read the file for every check.

Is there a way to remember the last value and compare it with the coming value? to write only new value into the file.

Hi,

I'm creating a remember me feature for my site which obviously sets a cookie and when the visitors loads the site again,he would already be logged in.

This is a part of the code which is related :
Code: [Select]
$login_email = request_var('login_email', '');
$login_password = request_var('login_password', '');
$login_remember = (isset($_POST['remember']) && $_POST['remember'] == 1) ? true: false;

setcookie('login_email', $_POST['login_email'], time()+60*60*24*365, '/','localhost',false);
setcookie('login_password', md5($_POST['login_password']), time()+60*60*24*365, '/','localhost',false);
HTML:
Code: [Select]
<strong class="normal"><input type="checkbox" name="remember" value="1">Remember</strong>

Hey guys not sure what this is called but does anyone have more information on it. Ok when you visit a part of a site or a profile or what ever??  :S:S and you redirect them to login how can u then send them back to where they was when they have logged in?

hope someone can help.

Time to ask a stupid question. I have a remember me cookie being set for my login page but I'm wondering what I need to do so that the next time the user comes back to the login page it already has the checkbox checked and the username in the username field which is the cookie.

I am wondering how to keep a checkbox checked?

I have the folllowing code and it is outputting the correct info, but when i tick checkbox, and then click box "SAVE Days and Recipes Chosen" the checkbox doesn't get set.

<?php
for($i = 0; $i < $rows; $i++) {
?>
<tr>
<?php
    for($j = 0; $j < $columns; $j++) {
            echo "<TD><font color='8678E9'>" . $data[$i + ($j * $rows)] . "</font></TD>\n"; ?>
            <td><input type='checkbox' name=$R1 <?php  if($R1=="checked"){$R1=="checked"; echo $R1;}
                                                        elseif($R1=="unchecked"){$R1=="unchecked"; echo $R1;} ?>

                <?php
    }
    echo "</TR>\n";

It is the following part that i cuurently  need help with

            <td><input type='checkbox' name=$R1 <?php  if($R1=="checked"){$R1=="checked"; echo $R1;}
                                                        elseif($R1=="unchecked"){$R1=="unchecked"; echo $R1;} ?>         

I haven't looked at the other checkbox part of

            <td align="centre"><input type="checkbox" name="ch1[]" method="POST" value=<?php echo $data3[$i + ($j * $rows)]?>,1 >M<br>           
                <input type="checkbox" name="ch1[]" value=<?php echo $data3[$i + ($j * $rows)]?>,2 method="POST">Tu<br>

Appreciate any suggestions

Hi guys,

I wonder if any if you could help me: I have created a login page with "remember me" function... The page will redirect either to Admin Page or User Page depends their 'level'.

But when I logged in as Admin and checked the box "remember me" and close all the browser to see IF the "remember me" work.

When I open a new browser - and go to the index page - it is okay, I can view the page.... but it redirect me to the USER page NOT Admin page.

Does anyone know why this happens?

Okay, this is a head scratcher for me...

About 10-15 years ago, there was this framework that seemed to be pretty popular in the LAMP work for quickly building websites.  (I think it was written in PHP.)

The thing I recall about it was that it you could create your own markup tags to markup up fields using curly brackets { }.

I wish I could be more specific but this is all that is coming to mind.

Any clues of what I might be thinking about?
