[Resolved] PHP Version Upgraded to 4.3.2 | Now Receiving Undefined Errors

Gary_Kambic

Hello,

My Web Hosting company finally upgraded their version of PHP from 4.0.3 to 4.3.2.

Now I am receiving the following error on variables passed with a POST from one of my pages:

"PHP Notice: Undefined index: checkbox2 in /hermes/data11/b364/tnevni/subscribe_send_preview.php on line 29"

I added the following line of code at the top of the page:

$checkbox2 = $_POST['checkbox2'];

I'm still receiving the error.

I assume they have Register Globals turned OFF in the php.ini.

Any help would be appreciated, thanks, Gary

do you have any other variables that would need the

$variable = $_POST['variable'];

conversion, maybe post some of your code

Gary_Kambic

This is the page with the post (abbreviated):

---------------This the page it calls when Submitted:
$checkbox2 = $_POST['checkbox2'];

if ($checkbox2 == "ON") {
$valid_email_address_one = "no";
$valid_email_address_two = "no";
if ( ($homeownername2) == "" ) {
$error_status = "yes";
$error_message .= "<table width=\"760\" border=\"0\" cellspacing=\"0\" cellpadding=\"0\">
<tr>
<td height=\"20\" width=\"20\"><img src=\"images/red_triangle.gif\"></td>
<td height=\"20\" align=\"left\" valign=\"middle\"><font size=\"2\" face=\"Verdana, Arial, Helvetica, sans-serif\"><strong>HOMEOWNER [2] NAME FIELD IS BLANK</strong></font></td>
</tr>
</table>"; }

I receive errors on all my variables that are arranged or passed like this now. Ever since they upgraded last night I've been receiving these notices. I understand that 4.3.2 is more particular than 4.0.2, I'm just trying to figure out how to adjust the code to accomodate the new version.

Thanks for the help

just try doing

echo $_POST['checkbox2'];

Gary_Kambic

Thanks, I'll try it and will let you know. Gary

I tried the statement and I still receive the error:
It did echo out "ON" which is correct because I did indeed check the box.

PHP Notice: Undefined index: checkbox2 in /hermes/data11/b364/tnevni/subscribe_send_preview.php on line 30

Any other thoughts?

I've researched most the forums and there really isn't any good answer. Seems like most people are having the same trouble. Gary

This error is because you are doing $POST[checkbox2] instead of $POST['checkbox2'].

It needs to be a string in the [] not a CONSTANT.

It is because the error message settings in php.ini have changed for 4.3.2.

This is the current code in the called page:

$checkbox1 = $POST['checkbox1'];
$checkbox2 = $POST['checkbox2'];
$checkbox3 = $POST['checkbox3'];
$checkbox4 = $POST['checkbox4'];
$checkbox5 = $POST['checkbox5'];
$checkbox6 = $POST['checkbox6'];

This is the output when executed:

PHP Notice: Undefined index: checkbox6 in /hermes/data11/b364/hintsforhomes/subscribe_send_preview.php on line 34
PHP Notice: Undefined index: checkbox5 in /hermes/data11/b364/hintsforhomes/subscribe_send_preview.php on line 33
PHP Notice: Undefined index: checkbox4 in /hermes/data11/b364/hintsforhomes/subscribe_send_preview.php on line 32
PHP Notice: Undefined index: checkbox3 in /hermes/data11/b364/hintsforhomes/subscribe_send_preview.php on line 31
PHP Notice: Undefined index: checkbox2 in /hermes/data11/b364/hintsforhomes/subscribe_send_preview.php on line 30

Notice that no error is displayed for checkbox1 because I checked that box on the calling page. The value is "ON" when the box is set.

I seem to be getting the errors when null is passed.

Thanks for the reply. Any thoughts?

Checkboxes only get sent if they are clicked.

if( isset( $_POST['checkbox6']) )
    $checkbox6 = $_POST['checkbox6'];

HalfaBee

Gary_Kambic

if( isset( $POST['checkbox1']) )
$checkbox1 = $POST['checkbox1'];
if( isset( $POST['checkbox2']) )
$checkbox2 = $POST['checkbox2'];
if( isset( $POST['checkbox3']) )
$checkbox3 = $POST['checkbox3'];
if( isset( $POST['checkbox4']) )
$checkbox4 = $POST['checkbox4'];
if( isset( $POST['checkbox5']) )
$checkbox5 = $POST['checkbox5'];
if( isset( $POST['checkbox6']) )
$checkbox6 = $POST['checkbox6'];

We just seem to be going in circles. I placed the code and I receive the same error.

I'm very confused. How do I change the null condition in the variable before the system checks the statement and gives me the error? Do I need to do something in the calling page before the "Submit" ?

HalfaBee

Try this then

if (array_key_exists("checkbox6", $POST ))
$checkbox6 = $POST['checkbox6'];

The other works fine for me ( on windoze server ).

What error are you getting now?

This works fine on both a unix host and windoze.
I even set
error_reporting = E_ALL
in php.ini to see what happens.

You can always use import_request_variables() or extract() to do the same thing.

You will still have problems if you test a value that has not been set you may have to set them before the extract();

It worked when I did then following: Just moved "" into the variable on the else consition. Thanks again, you got me here!

if( isset( $POST['checkbox1']) )
$checkbox1 = $POST['checkbox1'];
else
$checkbox1 = "";

if( isset( $POST['checkbox2']) )
$checkbox2 = $POST['checkbox2'];
else
$checkbox2 = "";

if( isset( $POST['checkbox3']) )
$checkbox3 = $POST['checkbox3'];
else
$checkbox3 = "";
if( isset( $POST['checkbox4']) )
$checkbox4 = $POST['checkbox4'];
else
$checkbox4 = "";
if( isset( $POST['checkbox5']) )
$checkbox5 = $POST['checkbox5'];
else
$checkbox5 = "";
if( isset( $POST['checkbox6']) )
$checkbox6 = $POST['checkbox6'];
else
$checkbox6 = "";

Well, maybe I spoke too soon. When I tried it in another script it didn't work. If you wouldn't mind taking a look:

<?php

$menu = $GET_['client_url'];

if( isset( $GET['client_url']) )
$client_url = $GET['client_url'];

if($menu)
{
header("Location: $client_url");
exit;
} else
{
?>

PHP Notice: Undefined variable: GET_ in /hermes/data11/b364/tnevni/menu.php on line 3

I substituted GET for POST, but I also tried it with POST and I also put the isset condition before $menu = $GET_['client_url'];

???

HalfaBee

You must be overtired. 🙂

$GET not $GET

HalfaBee

Gary_Kambic

PHP Notice: Undefined index: client_url in /hermes/data11/b364/hintsforhomes/menu.php on line 3

<?php

$menu = $_GET['client_url'];

if( isset( $GET['client_url']) )
$client_url = $GET['client_url'];

if($menu)
{
header("Location: $client_url");
exit;
} else
{
?>

Boy, this is driving me crazy, and yes I'm very tired. It's been one hullava day! :-)

Time for a debug ( and a coffee ).

Put print_r( $_GET ); at the start and see what is being returned.

HalfaBee

Gary_Kambic

Coffee, Hmmm, not a bad idea!

Here's the output:

Array ( [action] => login )

Gary_Kambic

Actually it's giving me errors on the GET and the variable $action:

PHP Notice: Undefined index: client_url in /hermes/data11/b364/hintsforhomes/menu.php on line 3
PHP Notice: Undefined variable: action in /hermes/data11/b364/hintsforhomes/protection.php on line 26
PHP Notice: Undefined variable: action in /hermes/data11/b364/hintsforhomes/protection.php on line 21
PHP Notice: Undefined index: client_url in /hermes/data11/b364/hintsforhomes/menu.php on line 3

Menu.php calls protection.php where the login is validated, if OK, it returns to menu.php and continues the script:

Protection script:

if( isset( $POST['action']) )
$action = $POST['action'];

if ($action == "logout")
{
include($logout_page);
exit;
}
else if ($action == "login")
{
/ echo "login_email_address: " . "$login_email_address" . "<br>"; /
if ($login_email_address == "")
{
include($invalidlogin_page);
exit;
}
else
{

Menu script:

<?php
print_r( $GET );
$menu = $GET['client_url'];

if( isset( $GET['client_url']) )
$client_url = $GET['client_url'];

if($menu)
{
header("Location: $client_url");
exit;
} else
{
?>

<?php
include("protection.php");
