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&amp;do=view&amp;clientID=$clientID\">".$clientname."</a>";
$client = "<a href=\"index.php?page=Project&amp;do=view&amp;sortby=$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.

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?

thanks

please help!

I am getting undefined index and offset when I duplicated my SEARCH page for when logged in

here is my code
