PHP passes variables it initalizes, not all.
You should check if the variable is set with the "isset" function.
Anyway, if you want. post your code, and I'll take a look at "line 27", wich
should be referring to an "array element" corresponding to a non-selected
checkbox.

Take this for an example :

This script fills part of a form with checkboxes named C1,C2, ect

   $cnt=0;
   for ($i=1;$i<=$n_alunos;$i++) {
    if ($cnt==0) {
     print "<tr>";
    }
    print "<td><input type=\"checkbox\" name=\"C$i\" value=\"on\">Aluno
$i</td>";
    $cnt++;
    if ($cnt==$colunas) {
     print "</tr>";
     $cnt=0;
    }
   }

This script receives the result from the previous form, and checks wether
checkbox C2 is set or not

if (!empty($_POST['C2'])) {
$b = $_POST['C2'];
}
else {
$b = "vazio";
}


An example ...

Try this

<?

    $i = 0;
    echo '<form>';
    echo '<input type="checkbox" name="temp['.$i++.']" value="3124">';
    echo '<input type="checkbox" name="temp['.$i++.']" value="6345">';
    echo '<input type="checkbox" name="temp['.$i++.']" value="456243">';
    echo '<input type="checkbox" name="temp['.$i++.']" value="45">';
    echo '<input type="checkbox" name="temp['.$i++.']" value="6756">';
    echo '<input type="checkbox" name="temp['.$i++.']" value="4567">';
    echo '<input type="submit" name="submit" value="test">';
    echo '</form>';


//Then in PHP whether the box is checked or not your indexes are
correct.

print_r($temp);
?>

<input type="checkbox" name="temp[0]" value="2352">
<input type="checkbox" name="temp[1]" value="47856">
<input type="checkbox" name="temp[2]" value="478">

When submitted this will create an array in PHP.  

This is the output of a test run

Array
(
    [0] => 3124
    [3] => 45
    [4] => 6756
)

Notice the indexes.

while (list ($key, $val) = each ($temp)) {
    echo "$key => $val<br />\n";
}

Must be whitout coffee, but don't see the point.
The passing of check boxes comes from the fact of selecting them or not.
I tried to insert your code and got nowere. How do you see if in between
those boxes, one in the middle is set ?

First some data about my setup:
PHP 4.2.3 (I bet nothing has changed till PHP 4.3.2 regarding 
sessions) running on Windows 2K server

My PC:
Windows 98 SE
Browser:
IE 6.0.2600.0000

Now, the problem occurs when using sessions and header 
('Location: ...');

test1.php
/**********************/
<?
  session_save_path ('c:/winnt/temp/'); //making sure that the path 
is correct, I override any value set in php.ini
  session_start ();

  $_SESSION ['someVar'] = 'Hello';
  session_write_close (); //saving session data and closing it
  header ("Location: http://hqserver/....../test2.php";);

  //echo '<a href="http://hqserver/....../test2.php";>To 
test2.php</a>';
?>

test2.php
/**********************/
<?
  session_save_path ('c:/winnt/temp/');
  session_start ();
  var_dump ($_SESSION);
?>

So, when I first open browser and go to test1.php I get redirected to 
test2.php and see this output:
array(0) { }
When I edit the link in IE linkfield from test2.php (rememeber.. 
there was a redirect) to test1.php and open it once again, I get:
array(1) { ["someVar"]=> &string(5) "Hello" }

If I comment out header in test1.php and uncomment the HTML hyperlink 
and go to test2.php using it, it works from the first time.


Thanks for any help solving this issue.

Cheers,
Donny

I'm not sure of in which version of PHP there was a problem like the one i'm describing, but i remember very well that i've made a Javascript redirector to place in the end of the page (after the session manipulation) to force the current page to go to the browser whole and then in the browser be redirected to the new page where the session was needed...

Hope to have been usefull (and perceptible, from my english ;) )

Thanks Luis,

I had this idea in mind, but still... maybe someone knows a way how to
achieve same effect without using JavaScript? Not that I don't like it but
that there should be some way.


PS. Your english is just as great as mine :D

One of the things that can be happening is that the server is sending 
the "location:" before the session data in the header... and when the 
browser gets it, simply forgots the session data.

I'm not sure of in which version of PHP there was a problem like the one 
i'm describing, but i remember very well that i've made a Javascript 
redirector to place in the end of the page (after the session
