This is what I do for error checking:
ini_set('error_reporting', E_ALL | E_STRICT);
ini_set('display_errors', 'On');
ini_set('log_errors', 'On');
ini_set('error_log', 'error_log');
Is this:

2. An overkill?
3. OK?
4. OR, better served with this (and provide an example).

When I'm in development mode, I leave out the last two settings and take
my error messages from the screen. Simpler, quicker. I use an include
file that is based upon a switch. When it's on, I set my devl settings,
when not, I set my prod settings.

[PHP] Re: error checking a null array
From what I understand the simplest solution here would be to check to see
if you have $_POST['cb'] in the first place. That would indicate if
checkbox was selected or not. After, you have posted the form just do the
following test.
$check_box_exits = ((isset($_POST['cb']))? true:false);
hope this helps...

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 }

wtf are you smoking Jack? every checkbox that was checked will exist in the

because the values mere existance in the submitted data indicates it's chevckbox
was checked), if a checkbox does not exist in the $_POST array it wasn't
checked!!!
imagine you have 10 checkboxes named 'cb1' thru 'cb10' each with a value of '1',
upon submitting the form they are in, your script sees the following in the
$_POST
array...
$_POST = array('cb1' = '1', 'cb9' = '1', 'cb10' = '1');
which tells you 3 checkboxes were checked... namely 'cb1', 'cb9' and 'cb10'
now how hard is it to determine which we're not checked?
maybe I'm not seeing the problem but I get the impression that you are
over complicating things regarding checkbox.

You can pass those names in a hidden input field in the form,
something like this:
input type=hidden name=checkboxes value=one box, two box, three
box, four!

Yes, or you can make your life easier and use radio buttons instead - the
name:value is always passed without any need for the messing about which
checkboxes bring. However, if you wish to use checkboxes, Jochem and Dotan
are showing you the way.

no you don't, you want to go home and rethink your life ;-)

Well, for me, it is - because I don't know the names of the other check
boxes which were not checked because they were dynamically created, and
you wouldn't be the one who wrote the script that creates them dynamically
would you?
and if you hit the same URL 100 times you get the same checkboxes? (i.e. its
checkbox output is reproducable) ... of so you have the basis for dynamically
checking which
checkboxes where presented to the user by using the same logic/algorithm to
check for there exist on submit as you use to generate them in the first place.
if your smart/able (and it's posible) you will wrap this logic up in some kind
of function in order to not duplicate code/logic...
in fact you could just store all the names of these checkboxes in a
multidimensional
array in the session when you create them and use that as the basis to check
for [non]existance.
I don't have the knowledge sufficient to pass the NAMES of all
???
checkboxes through to $_POST so that I can search through and see which
have been answered and which ones not.
why is it important to know what was not checked?

Re: [PHP] Re: error checking a null array
AAarg.
Okay, thanks to all of you I've decided that any field name I need to
see will be sent to $_SESSION['required_fields'] and basta.
Then after the submit button is pressed, I am doing this:
reset($_SESSION['required_fields']);
foreach ($_SESSION['required_fields'] as $fieldname)
{
if (!isset($_POST[$fieldname]) || empty($_POST[$fieldname]))
{
$message[$fieldname]=1;
include_once(QUESTIONS . 'q.inc');
}
}//error check
And this is *almost* working: it seems to crap out after the first loop
through the $_SESSION['required_field'] array.
The array says:
Array ( [required_fields] = Array ( [0] = 1 [1] = 2 [2] = 3 [3] = 4
[4] = 1 [5] = 2 [6] = 3 [7] = 4 [8] = 1 [9] = 2 [10] = 3 [11] =
4 ) )
$_POST says:
Array ( [action] = [process]process [1] = [2] = 68 [3] = [4] = )
So you see, there's an answer specified for the value of question [2].
But $messages says only:
$message: array(1) { [1]= int(1) }
Why is it dying after the first loop through?
Thanks in advance

I can only swear this to the entire list:
Before I come here for help, each time, I echo and var_dump and print_r
until, yes, I need a doctor.
So by the time I come here, it's not laziness or lack of looking in the
manual, it's head-swirling confusion infused with incompetence and a
complete lack of programming experience at any time before April of this
year which leads me to come back again and again with relatively foolish
questions.
My problem before, for example: In my error check function, I placed the
include file (to return to the form) *within* the foreach loop, and then
I wondered why it only ran through once.
D'oh.

I would have thought so too, but empty doesn't seem to work if it's not
there at all, (I guess it figures, how can it be empty if it isn't
there) and isset doesn't work if the array is there but null. or
something like that. IN any case I've yet to get them working using
either. I probably should have said that!
