Hello,

First of all, sorry for my bad english, i'm french..

Yesterday, i've downloaded the newest Firefox, installed it. I run my local website (on a local network), and i found a bug.

When in PHP, i said :

if ($_POST['object'] == "") {$_POST['object'] == "NULL";}

Problem : $_POST['object'] doesn't return "NULL" but return "" (empty string)
The only solution i've found is to backup to Firefox 3.6..

Do you already know about this bug ?

Thanks a lot.

Reproducible: Always

Please can you attach a testcase URL.

Also, could you see if the issue occurs if using Firefox in safe mode:
http://support.mozilla.com/kb/Safe+Mode

How about with a new, empty testing profile? (Don't install any addons into it)

What do you try to submit? Do you have a testcase?

Sorry iphone wrong touch :p

well, i'll try when i'll return to work on Monday.

Ed : whats a testcase url ?

Mounir : i'm trying to submit INT & Strings. The page worked good with firefox 3.6 so it's not a developement error. In PHP, i said if there's no number for 'object' i assigned NULL value. I've also try the function : empty.

The problem is that i don't know why updating to v4 changed the result.. Coincidence with html5 ?

Comment 5

[Ed Morley [:emorley]]

I meant do you have a URL where we can test the bug, in order that the regression range can be found?

Also, perhaps try going to about:config and flipping html5.parser.enable to false and seeing if that makes a difference (remember to set it back to true afterwards).

Ed : no i don't have because, as i said up, it's a local website..

I'll this afternoon (if i can) or tomorrow, every solutions you gave.

Any luck with comment 5?

Does this still occur when using Firefox 4.0.1 and a clean profile?

Hi Demigen,

Can you please attach a minimal test case, so I can test this on my end?

Also, can you please test this on the latest Firefox release (44.0.2) or latest Nightly (47.0a1, https://nightly.mozilla.org/) and tell me if this still reproduces for you ? When doing this please use a new fresh Firefox profile, maybe also in safe mode (https://support.mozilla.org/en-US/kb/troubleshoot-and-diagnose-firefox-problems).

Thanks,
Cosmin

Hi Demigen,

It would be great if you can provide a part of code and steps to reproduce, so I can test this on my end. Also, it would be helpful if you post the error. What do you mean by v39.9 solved your problem?

Thanks,
Cosmin.

Comment 17

[Cosmin Muntean [:cmuntean], Ecosystem QA]

Hi Demigen,

I have tried to test this on my end, with a localhost server using XAMPP and NetBeans. I have run the code with NetBeans but there is an error at line 17 on function "require_once()" (see atachement). If I delete this line, the page loads without error. Then, if I write anything in the input fields and I press the "Rechercer" button I have got this error at line 39 on function "NumberExist()"(see attachment). Please provide a functionally test case in order to test this.  

Thanks,
Cosmin.

Hi Cosmin,

Well "NumberExist()" is just a function to be sure that enter's number is in database, so you can skip this function or simulate it.

Have a nice day,

Demg
