Having trouble with Array of Checkboxes and FileUpload

[mfaisalnice]

I created a page that contains list of checkboxes in a loop like,

<input type=checkbox name='CHK[]' value=LoopValue>


I am posting this page to an another PHP page
where I have written
$chk = $_POST['CHK'];
print_r($chk);

and as a reasult it is showing me nothing.. while I have selected some checkboxes as well.
Same problem with <input type=file name=file>

This is all working in PHP 4 while it is not working in PHP 5.2.6.

[kows]

well, you didn't really post any code, but I made this script:

<pre>
<?php
  echo "php=" . phpversion() . "\n\n";
  print_r($_POST);
?>
</pre>
<hr />
<form method="post">
<?php for($i = 0; $i < 5; $i++): ?>
  <input type="checkbox" name="check[]" />
  <input type="file" name="file[]" />
  <br />
<?php endfor; ?>
  <input type="submit" value="submit" />
</form>

that script returns this example output for me:

php=5.2.9

Array
(
    [file] => Array
        (
            [0] => 
            [1] => 
            [2] => 
            [3] => 
            [4] => 
        )

    [check] => Array
        (
            [0] => on
            [1] => on
        )

)

remember, check boxes are either on or off; if they are on, they are set. if not, they aren't set (like in my example, I checked the first two checkboxes and not the last three). file inputs, however, are always set when present in a form.

[mfaisalnice]

Thanks..

OK I copied ur code and select some checkboxes and select some file... and thats what am I getting as a result

Array ( [campaign] => 1 [check] => [Submit] => Update )

[check] is blanked while i have selected some checkboxes
Its not even showing there is a file or somthing. and not showing selected checkboxes as well.

[SambaNeko]

I don't see how that can be output from kows' code; there's no "campaign" field, and "Submit" should have a value of "submit" if this were the result of kows' example...

Either post what you're using, or use kows' example exactly as-is and tell what happens.

[kows]

yeah, I'm not sure how you modified my code, but you definitely changed a bunch of it. you should now A) post whatever code you're actually using (we can't help you if we don't know what you're doing), and B) running the code that I originally posted without any modifications.

and just as a side note, there is no need to name your submit buttons unless you have multiple submit buttons for the same form. like in my code, all you need are the following attributes:

<input type="submit" value="submit" />

I'm not sure why, it's just a pet peeve of mine.

[mfaisalnice]

I dint change Kow's Code too much... his code is simple and i just put it as it is.. well you named a button or not dosent matter.. Campaign field was a combobox which dosent matter either... I am sorry i couldnt post the actuall code.. anyway
Thanks Guys...well.. I found the solution

I used GET instead of POST and all my checkboxes were available to me as an Array... i dont knw the reason.. but it worked that way

I found that the GOLBAL_VARIABLE is set to OFF in PHP 5 for security reason thats why I can not upload file and I can not see file box result on other page...
Well GLOBAL_VARIABLE is set to OFF in PHP 4 as well.. but Uploading a file worked in PHP 4 regardless the ON n OFF...

As soon as I will be able to turn it ON I will let you guys know... I hope my File Upload will work this way...

Many Thanks...

[SambaNeko]

I used GET instead of POST and all my checkboxes were available to me as an Array... i dont knw the reason.. but it worked that way

This means your form was probably set up as:

<form method="get">

...or just "<form>". In either case, the GET method is used to send and retrieve data. To use POST, do as kows did:

<form method="post">

As soon as I will be able to turn it ON I will let you guys know... I hope my File Upload will work this way...

Ugh, do you mean the "register_globals" setting? That's turned off by default in PHP 5 for good reason, and yours is not an appropriate reason to turn it on. Post your code and perhaps we can tell you how to fix your file upload without opening up a security hole.

That is because you have the method attribute of the form tag in you HTML either missing or set to "get". I recommend you change it to "post".

It occurs to me that you are changing things that you do not understand. This is one of the best ways to create a page with security flaws. I am also willing to bet that you are not properly validating your variables, which could also lead to security flaws.

Why is it that you cannot post your code? I am pretty sure there is nothing in it that we want to steal. At the very list, send it in a private message to kows or myself.

[SambaNeko]

It occurred to me, I bet I know what's wrong with your file upload. Your form tag needs to include this:

<form method="post" enctype="multipart/form-data">

[mfaisalnice]

OK here is my Coding Files... all your guidance is appreciated guys.

it is the first File that contains FORM

Now again it is working at my office and showing me FILE as well... I am using Windows XP, PHP 4

IT is not working on my client page and showing me only RADIO BUTTON ... CLIENT is using LINUX, PHP 5....

I think it has to do somthing with the Global Variable is set to OFF...in PHP 5

Please help soon guys

Thanks in Advance

[SambaNeko]

OK here is my Coding Files... all your guidance is appreciated guys.

it is the first File that contains FORM

So what result are you getting from this, if not the one you expect?... I tried this on my (PHP 5.2.6) server and it worked as expected - all form data (including file data) was received by the addmanufacturer.php script.

I believe there was also a recent thread concerning the storing of image data in a db... and why it's a bad idea.

As for your second example, print_r($_POST) will not show file data, because it's stored in a different array: $_FILES. So, add print_r($_FILES);

Are you Using LINUX OS???... well $_POST at least shows the FileName because I tried it with GET <form action='GET'> and $_GET were showing me the file name?

[SambaNeko]

Yes Linux. I'd still like to know what result you're actually getting; could you replace the entire contents of addmanufacturer.php with this code, and tell me what you get when you submit the form to it?

<?php
echo "php=" . phpversion() . "\n\n";
print_r($_REQUEST) . "\n\n";
print_r($_FILES) . "\n\n";
?>

[kows]

oop, remember that print_r() is a function that doesn't return output (but rather outputs itself), so make sure it's:

<?php
echo "php=" . phpversion() . "\n\n";
print_r($_REQUEST);
print_r($_FILES);
?>

like previously mentioned in this thread, though, if you're talking about register_globals when you say "global variable," that setting would have nothing to do with any of this. it would not affect anything you're doing, and it's a deprecated setting for good reason.

[mfaisalnice]

Kows,

Here is the result i got when I use your code..

CODE
==============
<?php
echo "php=" . phpversion() . "\n\n";
print_r($_REQUEST);
print_r($_FILES);
?>
============

RESULT
==================
php=5.2.6 Array ( [rdoFileType] => TabDel [Submit] => Save ) Array ( )
================



Hope you can help me soon.

Many Thanks

Some thoughts for you:

- make a file called phpinfo.php, and put this code in it:

<?php
phpinfo();
?>

This will generate a page with your server's PHP configuration settings. Do a Ctrl+F for "file_uploads" - is that set to "on"?

- also on the phpinfo file, look for "upload_max_filesize" and "post_max_size" and make sure the file you're trying to upload isn't bigger than those

- does your file name have any non-alphanumeric characters in it?

- your form has some Javascript that's running onclick of the submit buttons, and onsubmit of the forms - what are these scripts doing? Could you post them as well?

[mfaisalnice]

Hi SambaNeko

I tried the code u mentioned me..

file_uploads is SET to ON

Upload_max_filesize = 2M

post_max_size = 8M

my file does not contain any non-alphanumeric characters.

JAVA SCRIPT( I tried to remove every thing..and just the file box were there with FORM and it still dint work out)

JS was simple as below
function onSubmit()
{
if(form.textbox.value == "")
{
alert("You Must fill this text box");
}
}

RIGHT NOW... I have a simple page with a Filebox n submit button and the FORM Tag in it... and on the other page I see nothing in FILES array

Please help
