Re: [PHP] $_post and array question

[Amon]

Thanks for help Daniel Clark. I know i must use isset function but that was
not the issue. But thanks anyway:)

Curt Zirzow thanks for your reply also. But that has nothing to do with
reference. If you use reference or not.. it still would not result in an
error (hee... I want an error :P)

Matt Matijevich thanks for your reply as well :)
My function is already declared something like this:

function testX($testArr)
{
$arr_test = $testArr;
return $arr_test;
}
Even if you send a reference parameter ($testArr).. the outcome will not
result in an error.

I guess somehow PHP does something to the function argument if it does not
exist: creating it and give it the NULL value. But this should at least give
us a warning because it could result in unwanted code!

But i dunno know this for sure. Could anybody help me on this?

[PHP] $_post and array question

[Amon]

Best readers,

//PHP version: 4.3.6

I have question concerning the following issue:

I have a HTML input element of the type check.

input type=checkbox name=test_arr[]

let assum this checkbox is unchecked. The checkbox is part of a form.
Now we gonna submit this form (post) and gonna catch the POST variable
test_arr like this:

$arr_test = $_POST[test_arr];

This will result in a novice error Undefined index: 
Of course because test_arr does not exist. It's unchecked.

Now we gonna do the following:
We immediately put the $_POST[test_arr] into a function and then we assign
$_POST[test_arr] to $arr_test like this:

functionX($_POST[test_arr])
$arr_test = $_POST[test_arr];

Knowing that $_POST[test_arr]) does not exist.. this code will not result
in a error.

Is this a bug,error,etc? Should this not also produce a novice error?

Thanks for reading,
Amon

I think when you are doing this

functionX($_POST[test_arr])
$arr_test = $_POST[test_arr];

$_POST[test_arr] is a local variable to the functionX, not the $_POST
superglobal. (I might be wrong)

try to define you function like this:
functionX($testArr)
$arr_test = $testArr;

and call it like this:
$test = functionX($_POST[test_arr]); //you will probably get your
undefined index warning here

Re: [PHP] $_post and array question

[Daniel Clark]

I've done a couple things. One is to use isset() and check first.
The other is to add a hidden input field, that way something is always sent.


input type=hidden name=test_arr[]

input type=checkbox name=test_arr[]
input type=checkbox name=test_arr[]

* Thus wrote Amon ([EMAIL PROTECTED]):
 
 functionX($_POST[test_arr])
 $arr_test = $_POST[test_arr];
 
 Knowing that $_POST[test_arr]) does not exist.. this code will not result
 in a error.

Taks a look at the definition of functionX I bet it looks something
like:
  function functionX($var) { }

The same non-notice effect can be done like:

$var = $_POST['test_arr'];

This is more of a side effect of assigning by reference.
