[PHP] Other Notice problem...
This is not the same question i asked yesterday. When i set error_reporting = E_ALL and display_errors = On in my php.ini, i get the next message: Notice: Undefined variable: varname in . How can i fix this problem without setting error_reporting = E_ALL ~E_NOTICE and/or display_errors = Off, or what way do you think is the best to resolve this problem?

Re: [PHP] Other Notice problem...
This usually means that you're using a variable without having initialized it. For example $a = $b + 1; will give you that warning if no value is assigned to $b prior to this line. It's PHP's way of telling you that you might be doing something wrong. Perhaps if you post some of your code we can help better?

But it's the same answer ;-)
If you want to be completely warning-and-notice-free, you need to define
the variable before accessing it:
// this will give a notice
echo $undefined_var;
// and this won't
$define_var = 'some data, or simply put null here';
echo $defined_var;
The same holds true for array indices:
$test_array = array('One', 'Two', 'Three');
// this will give a notice
echo $test_array[3];
// and this won't
echo $test_array[2];
// and this won't as well
if (array_key_exists(3))
echo $test_array[3];
Get the idea? IMHO it's complete overkill with PHP to predefine variables
since they're auto-initialized with NULL when used first. These notices are
only for the development cycle, to aid us in spotting a problem where you
expect some data to be there, but it aint because the variable name has
been mistyped...

Re: [PHP] Other Notice problem...
My code is:
?php
some code.
if ($status == ADD) {
some code ...
...
...
}
?
The message is: Notice: Undefined variable: status in
I'm going to explain how my script work.
I have an php page (addProduct.php) with an input form. I have 2 buttons
(add and cancel) and a hidden control with name=status. If i press the add
button, the page submit the form data to the same page (form
action=addProduct.php) with status hidden control name set to ADD, so the
if statement its true only if i press the add button.
I see the message when i call the page to add the data not when i submit the
data.
How can i fix the problem? or there is another best way to do this?

Re: [PHP] Other Notice problem...
Try
if (isset ($status) $status == 'ADD')
instead... this should take care of the error--IF you're sure that the
fact that the $status variable is not set at that point is ok.

Ahhh your $status variable should be a form variable? Well, as pointed
out many times the last days, register_globals is OFF by default since PHP
v.4.something. Either turn register_globals on in your PHP.ini (bad and
deprecated, read the security bulletins), or you refer to the _POST array:
if ($_POST['status'] == ADD)
if the data is not set (the status control empty), you'll still get a
notice about an undefined array index, so you might
if (array_key_exists('status', $_POST)) {
switch ($_POST['status']) {
case 'ADD':
break;
default:
echo 'Unsupported status!';
}
}
else echo 'No status sent!';

Re: [PHP] Other Notice problem...
The array_key_exists or isset is a good solution.
About your comment, i have the register_globals=on.
I have 2 questions:
1.- What's the relation to have register_globals=off with this notice
message?
2.- I read the security comment about register_globals=on in the php.ini,
but i set to on because if i set to off, i can't pass GET variables to other
page. how can you pass GET variables to other page without setting
register_globals=on?

About your comment 1:
if i have register_globals=on, why $status is not be set by PHP?
well _then_ we have 2 possibilities:
1) your form input field isn't named status but rather Status or
STATUS - take care of the case here, PHP is case sensitive with variables
and associative indices.
2) Your form simply submits _nothing_ in this field - check your JavaScript
(perhaps it is disabled?)
About your comment 2:
if i have 2 pages: p01.php and p02.php,
with p01.php code:
...
a href=p02.php?pp=2link/a
...
and p02.php code:
...
echo $pp;
If i have register_globals=off, then when i click the link, in p02.php page,
the echo command display nothing.
If i have register_globals=on, then the echo command displays the value buy
this way is deprecated.
How can i run the script without problems having register_globals=off?
?php
$parms = null;
foreach ($_GET as $p=$v) {
if ($parms) $parms .= '';
$parms .= $p=.urlencode($v);
}
?
...
a href=p02.php??php=$parms?
This will do what you want (untested, but should work)
