PHP - Undefined Index Problems

Undefined Index Problems	View Content

So, for the past couple of years or so I've been using CodeIgniter to develop my PHP applications... which may have been a mistake. As of late, I've been trying to get away from frameworks and am developing an application purely on my own. I never had this problem with CI, but whenever I try to determine if a variable/index has been defined, I get an error. For example, if I use an if statement to see if a session index called "mid" was defined, I get a PHP error saying that it's undefined. Is there any way to get around this?

Code: [Select]
<?php
if($_SESSION['mid']){
echo $inbox;
} else {
echo 'Your not logged in!';
}
?>

Strange Undefined Variable And Undefined Index Notices

Similar Tutorials

View Content

Hello,

I have just upgraded my wampserver and with it MySQL, PHP and PhpMyAdmin versions. And my scripts, which ran normally before, not burst hundreds of undefined variable and undefined index notices. I realize it's "notices", not "errors" but this is quite irritating. I believe it might be due to some upgrade in PHP scripting rules or something but I don't know what. I hope you can help me.

The first type of notice is "undefined variable". This function will return the notice if I remove the bold red line, where I define the variable as empty before I use it in the loop. I didn't need to do this before.
function statistics($array) {

[color=red][b]$list = '';[/b][/color]

if(is_array($array)) {
foreach($array as $name => $value) {
// Rip out the name of the client.
$list .= "<li>".$name." - ";
// set an integer so we know how many tier2 values we have read.
$x = 0;
foreach($value as $difference => $sum_total) {
// if this is the more than the first tier2 values, use a '+' between the units.
$list .= (++$x > 1) ? " + ".$sum_total." ".$difference : $sum_total." ".$difference;
}
// close the line out.
$list .= "</li>";
}
}
return $list;
}

To avoid the 10+ like notices on the page I declare them empty before the variable's first occurrence. But this sounds stupid to me. Wasn't this one of PHP's benefits, not to have to declare the variable before using it?

I also get about 30+ undefined index notices, e.g.
Quote

Notice: Undefined index: COMPANY XXX in F:\wamp\www\Project Management\main.php on line 37

Notice: Undefined index: USD in F:\wamp\www\Project Management\main.php on line 37

Notice: Undefined index: USD in F:\wamp\www\Project Management\main.php on line 41

Here are those lines:
$income_total = calculate("income");
foreach($income_total as $row) {
$clientID = $row['clientID'];
$clientname = $row['clientname'];
//$client = "<a href=\"index.php?page=Client&do=view&clientID=$clientID\">".$clientname."</a>";
$client = "<a href=\"index.php?page=Project&do=view&sortby=$clientID\">".$clientname."</a>";
$currency = $row['currency'];
$client_sum = $row['client_sum'];
$year_sum = '';
$year_sum += $client_sum;
$income = '';
$income[$client][$currency] += $client_sum;

$income_list = statistics($income);
$income_all = '';
$income_all[$currency] += $client_sum;
}

Line 37 is: Quote

$income[$client][$currency] =

It's the values assigned to $client and to $currency that seem to cause the notice.

How do I deal with this? I don't just want to turn error/notice display off, I want to resolve this issue.

Undefined Index And Undefined Offset?!

my current code:

Code: [Select]
$Townsearch = $_REQUEST['rsTown'];
list($Town, $County) = split('[,]', $Townsearch);
ltrim($County,1);

I am getting undefined index and undefined offset, so I tried this:

Code: [Select]
if $_REQUEST['rsTown'] == ''{
$Townsearch = '';
} else {
$Townsearch = $_REQUEST['rsTown'];
}
but this brought back: Parse error: syntax error, unexpected T_VARIABLE, expecting '(' in D:\retroandvintage.co.uk\wwwroot\main.php on line 6

Can someone please help?

hi,
I need help really badly for my PHP-Postcard Script. Basically it sends the card out but the URL does not work, I get the following error message:

The URL is not valid and cannot be loaded

It also states that

Hi everyone! This is my first post.
Anyways I have been reading my amp book to learn apache mysql and php, but I ran into a bit of a problem that I cant figure out.
I will attach my 3 files for everyone to see.

I get this error after loading the login.php file and trying to type in the username and passowrd
From what I can gather the username is ok, but there is an issue on line 9 where the password authentication is located which has me baffled. I can't find any syntax errors....

I've gotten different "Notices" for "Undefined Index."

For different $_POST['vars'], I've corrected with adding an isset() at the top of my if condition.

I'm stumped now for how to approach my current notice. Am tempted to just block errors on my server, but don't believe that is really fixing it.

I've added a multiple select array to my form. I pass it correctly and access it fine. Only thing, for checking with error checking, if it is blank, the form will repopulate. If checked, the data passes correctly. If there are no selections, then I get the Undefined Index error from PHP.

I wrote a routine to check if it is null, but that doesn't seem to do it.

I want to check that it is not null, and if it is, then repost the form. If I put in isset(), it would never go past. If I don't put isset(), then it will cry with the error.

Any Thoughts?

Hi there i keep getting an error: Notice: Undefined index: ShipYard in C:\wamp\www\SWB2\test3.php on line 160

Heres the relevant select query:
Code: [Select]
// COUNT SHIPYARDS
$colname_shipyard = 'Empire';

mysql_select_db($database_swb, $swb);
$query_shipyard = sprintf("SELECT SUM(ShipYard) FROM planet WHERE PlayerName = %s", GetSQLValueString($colname_shipyard, "text"));
$shipyard = mysql_query($query_shipyard, $swb) or die(mysql_error());
$row_shipyard = mysql_fetch_assoc($shipyard);
$totalRows_shipyard = mysql_num_rows($shipyard);

The error is pointing to:
Code: [Select]
echo $row_shipyard['ShipYard'];Im a bit of a noob and have tried changing to:
Code: [Select]
echo $row['ShipYard'];
When i do this i get a different error: Notice: Undefined variable: row in C:\wamp\www\SWB2\test3.php on line 159

The row ShipYard is in a table called planet but its not suppose to be indexed or unique.

Am I missing something here??

Thanks

<?php
define ('page', 'page');

switch($_GET[page])

I've got this on my page index.php

$rand = $_SESSION['rand'];
if (empty($rand)) {
srand((float)microtime()*1000003);
$rand = rand();
$_SESSION['rand'] = $rand;
}

On all my other pages i've got this

<?php unset($_SESSION['rand']) ?>

The problem is that if I go to any other page than index it will unset the session 'rand'. If I then go back to index.php I get this error 'Notice: Undefined index: rand'

is there a way to get around this?
