Notice: Undefined variable

[Klaus_Lo]

Hello! Help me please!

My site nice work on php version 5.2.12, but now php version is changed to 5.2.17 and some code is not working.

 

 

It showing error: 

 

"Notice: Undefined variable: newCode in ....../humancheck.php on line 29"

 

In file humancheck.php on line 29:

for($i=0; $i<$config_max_digits;$i++)	$newCode = $newCode.rand(0,9);

This variable, it seems, taken from another file - humancheck_showcode.php:

session_start();
$newCode = $HTTP_SESSION_VARS["newCode"];

And, in index.php file at the beginning of the file written:

require ('human_check/humancheck.php');

And, in index.php file below is written:

 <IMG src="humancheck_showcode.php">

When I call the index.php file it shows error.

So, I think, that variable "newCode" should be taken from file humancheck_showcode.php, but it don't do that.

Line 31 of that first snippet is not valid php at all. It looks more like JavaScript.

 

We need more context.

What's not valid about this?

	for($i=0; $i<$config_max_digits;$i++) $newCode = $newCode.rand(0,9);

Test:

$config_max_digits = 10;
$newCode = "CODE";
 
for($i=0; $i<$config_max_digits;$i++) $newCode = $newCode.rand(0,9);
echo $newCode;

Output: CODE9094108549

To be honest, I thought the same thing. It took me longer than it should to realize that was a concatenation character between $newCode and rand(). I thought the OP was attempting to mix JS and PHP.

The undefined variable message is coming from your humancheck.php script. Is the SESSION variable being read into that script?

 

Side note:

$HTTP_SESSION_VARS has been deprecated; you'll want to use $_SESSION instead. More information can be found here:
