PHP - Notice: Undefined Variable & Call Stack

I'm getting the following notice:
Notice: Undefined variable: TotaalBerichten in
C:\Users\Sander\Documents\**********************\index.php on line 60
Is it because it is in the IF?
The code:

        //Aantal berichten totaal  
 if (!$ResultTotaalBerichten = @mysql_query("SELECT COUNT(1) FROM " . $db_prefix . "berichten"))
             {$foutmelding .= $Taal['errorConfiguratieFromDB'];}
         else
             {$TotaalBerichten = mysql_result($ResultTotaalBerichten, 0);
             $TotaalPaginas = ceil($TotaalBerichten / $aantalBerichtenPerPagina);}
         @mysql_free_result($ResultTotaalBerichten);

         //Var eersteBericht is het eerste bericht
         if (isset($_GET['eersteBericht']))
             {if (!is_numeric($_GET['eersteBericht']))
                 {$eersteBericht = '0';}
             else{$eersteBericht = $_GET['eersteBericht'];}}
         else{$eersteBericht = '0';}

        // Als er iets mis is met var eersteBericht, dan hem op 0 zetten
        if (($eersteBericht >= $TotaalBerichten) || ($eersteBericht < 0))   ///////////DIT IS LIJN 60
             {$eersteBericht = 0;}


EDIT: translated to english 

If i modify it to:

$TotaalBerichten=0; /////////////ADDED

The $TotaalBerichten is '0' while there IS a message in the database???

code is
Code: [Select]
<?php 
$limit=12;
if(isset( $_GET['page']))
$page=$_GET['page'];
if($page<=0) $page = 1;

else {$start=0;}
$sql=mysql_query("select * from tbl_gallery where status=1 And category_name='0'");
$count=mysql_num_rows($sql);
$totalcount=ceil($count/$limit);$start=($page-1)*$limit;
$s=mysql_query("select * from tbl_gallery where status=1 And category_name='0' limit $start, $limit");
while($result=mysql_fetch_array($s)){
$start++;

 ?>

please find the mistake

hello all, i have ran into another issue i get this message when i go onto my homepage

Notice: Undefined variable: layout in

i have the following includes on the main index page:

Code: [Select]
<?php
// Include Main Core File.
include '_class/core.php';

include 'layout/index.php';
?>

on the config file i have the varible it is refering too:

Code: [Select]
<?php
$layout = $url . "layout/";
?>

the actual file i get the error on (library.php)
Code: [Select]
<?php

class library extends core {

function advert() {

/*

// Change this to the total number of images in the folder
$total = "2";

// Change to the type of files to use eg. .jpg or .gif
$file_type = ".png";

is there a way to make it so it $layout works on any page or file as long as its in the includes?

thanks again.

I have a php page that is trying to pass a variable like this:

echo "<tr><td bgcolor='white'>" . $company_id . "</td><td bgcolor='white'><a href='companyusers.php?name=" . $company_name . "'>" . $company_name . "</a></td><td bgcolor='white'>" . $company_email . "</td><td bgcolor='white'>" . $company_status . "</td></tr>";

Then when some one clicks on that link they variable with it's value should go with the url and I'm trying to assign a variable like this:

$company_name = $_POST['name'];

It is not working!!! I get that "Notice: Undefined index: name in 'directory of page' on line 100"

Can someone help please?

Hello,
   I have the situation shown below in the code:

if(//condition is met)
{ $val = new Val();
  $valon = $val->check($_POST, array(.........));
}
if($valon->passes())
{ $use = new Use();
  ........
}
//check() and passes() both belong to class Val
public function check($source, $items = array())
{ ......................
  return $this;
}

I get the following warning and error:

Notice: Undefined variable: valon
and
Fatal error: Call to a member function passes() on a non-object

I can't see anything wrong with the code. check() returns an object of class Val which is assigned to $valon, $valon then calls a member function of class Val. Could you please help. Please let me know whether to include further code.

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.

Hi. I installed xampp to practice php scripting. Until today, it has worked fine, but now it says:
Notice: Undefined variable: text in E:\xampp\htdocs\Experiments\Tutorial\HelloWorld.php on line 6
What can I do to fix this? I'm told that variable don't need to be defined before being initialized, but that doesn't really mean much to me!
Please help

I have a form and a validation both on the same page, however I'm getting notices since I have undefined variables. How do I get around this?


Notice: Undefined index: submit in C:\xampp\htdocs\5dollar\register.php on line 10

Notice: Undefined index: password in C:\xampp\htdocs\5dollar\register.php on line 12

Notice: Undefined index: repeatpassword in C:\xampp\htdocs\5dollar\register.php on line 13

Notice: Undefined index: paypalemail in C:\xampp\htdocs\5dollar\register.php on line 14

$submit = $_POST['submit'];
$password = strip_tags($_POST['password']);
$repeatpassword = strip_tags($_POST['repeatpassword']);
$paypalemail = strip_tags($_POST['paypalemail']);
