hi,
I have checkboxes beging dynamically generated. to seperate tasks in
error checking I have added he arrays not just to $_POST but to
$_POST[cb] so names (derived from question numbers) are for example:
$_POST[cb][7]
A dump of $_POST would therefore include something like
["cb"]=> array(1) { [7]=> array(1) { [0]=> string(3) "124" } }
So I did this:
//error checking for checkboxes
foreach ($cb as $cbkey => $cbvalue)
{
foreach($cbvalue as $cbkey2=>$cb_answers)
{
if( !array_key_exists($_POST[$cbkey], $cb));
{
$message[$cbkey]=1;
}
}
}
This almost works. The problem is that if someone doesn't check a
checkbox, NOTHING related to the checkbox gets sent to $_POST; if I
insert a hidden value of something, then that hidden value gets passed
whether the user inputs something or not, since I need an entirely
server-side solution. Is there a way to send something to tell the error
checker whether for example $_POST[cb][7] is empty or null, so I can set
the error message to one if it's empty?
Dump of $_POST with no checkboxes checked
$_POST:
array(4) { ["action"]=> string(7) "process" ["cat"]=> string(1) "2"
["rs"]=> array(3) { [5]=> string(0) "" [6]=> string(0) "" [9]=>
string(0) "" } ["b"]=> string(8) "Continue" }
Dump of $_POST with checkboxes checked
array(5) { ["action"]=> string(7) "process" ["cat"]=> string(1) "2"
["cb"]=> array(2) { [7]=> array(5) { [0]=> string(1) "3" [1]=>
string(3) "124" [2]=> string(3) "125" [3]=> string(3) "127" [4]=>
string(3) "131" } [8]=> array(3) { [0]=> string(3) "141" [1]=>
string(3) "145" [2]=> string(1) "4" } } ["rs"]=> array(3) { [5]=>
string(0) "" [6]=> string(0) "" [9]=> string(0) "" } ["b"]=>
string(8) "Continue" }
Thanks so much In advance
