Cannot post hidden input after update PHP 5.3.8 to

Question

I upgrade my PHP v5.3.8 to v5.3.24. Since updating my script no longer works.

An input variable POST it's the problem.

Form source code here : http://pastebin.com/N4XKSQjR

The line problem is the following (last line):

<input type="hidden" name="count_result" value="416">

On my PHP processing form page (traitement.php) i recover this field like this:

 $count_result = $_POST['count_result'];

And i get this php error :

Notice: Undefined index count_result on line...

The script works without problems with PHP 5.3.8 but not with PHP 5.3.24.

Can anyone help me?

Thanks

Only solution I've been able to find, and based on the error I get while trying to duplicate the problem. Note, I tested this on PHP 5.4.x
The error:

Warning: Unknown: Input variables exceeded 1000

In my php.ini the line:

; max_input_vars = 1000

has been commented out - meaning it was defaulting to 1000. Prior to 5.3.9, this was not an option, therefore you didn't encounter the problem and it was unlimited ^^. With PHP >=5.3.9 it defaults to 1000, so to make your script compatible with so many inputs, you need to set that directive in PHP. I set it to 2000 and it worked perfectly.

Since you copied your old php.ini, it probably won't exist in there, so add:

max_input_vars = 2000

somewhere in there and it will at least work for your current example. ^^
