I have inherited a mess of a home-grown PHP framework that literally
fills the error_log with 100's of thousands of messages each day. First
order of business was rotating the logs, now we are working through each
error to solve them. This is a fairly basic error, but I for the life of
me cannot remember what the solution is.
I have a recursive function that reads from XML files and replaces xi:
include directives. It looks like this -
function includeXML($file, $locale, $url, $level = 1) {
// stuff
while(($line = fgets($fp)) !== false) {
if($pos === false) {
$xml .= $line;
} else {
includeXML('repository/' . $included, $locale, (int)$level
+ $pos - 1);
}
}
}
Why do I get the notice that $xml is an undefined index?
Because it's undefined. So is $pos. From what you've written above, both are
local to includeXML. But neither is passed in as a parameter, nor is global.
You can't initialise it within the function, it seems to me.
If $xml is supposed to be appended to and grown as you recurse up and down,
then you have two choices:
1) Make them global
2) Pass both as extra parameters to includeXML
In both cases, each needs to be initialised before the first call to the
recursive function
Solution (1)
$xml = '';
$pos = 0;// Presumably.
includeXML ($file, $locale, $url, 1);
...
function includeXML ($file, $locale, $url, $level = 1) {
global $xml, $pos;
// stuff
while(($line = fgets($fp)) !== false) {
if($pos === false) {
$xml .= $line;
} else {
includeXML ('repository/' . $included, $locale, (int)$level
+ $pos - 1);
}
}
}
Solution (2)
$xml = '';
$pos = 0;// Presumably.
includeXML ($xml, $pos, $file, $locale, $url, 1);
...
function includeXML ($xml, $pos, $file, $locale, $url, $level = 1) {//
Note the on the first parameter
// stuff
while(($line = fgets($fp)) !== false) {
if($pos === false) {
$xml .= $line;
} else {
includeXML ($xml, $pos, 'repository/' . $included, $locale,
(int)$level
+ $pos - 1);
}
}
}
BTW it seems to me that you'll have the same problem with $included unless
there's other code in includeXML that you've omitted.

There is obviously something else wrong. That's the purpose of isset(); Comment out your line and see what happens. I'd guess the real problem is later in your code when you are trying to do something with $HTTP_COOKIE_VARS[LoggedIn] even though your isset() test said it didn't exist.

[PHP] Re: undefined index and php
I tried this to set the value...
if (!isset($_POST['heading'])) {
$_POST ['heading'] = ;
}
because the following line give the notice 'undefined index' BEFORE the
submit button has been pressed..
? $heading_insert= stripslashes($_POST['heading']);?
What everyone else said, but also:
It's not good practice (in fact I don't even know if it's possible) to
modify the contents $_POST programmatically. It contains, as you no doubt
know, all of the variables POSTed to the script, generally by the submission
of a form with method=POST.
It would be better for you to assign the contents of $_POST to local
variables. Firstly, you will be able to do any necessary checks and
modifications (length, variable type, presence of illegal characters and so
on) at the point when you create the variable. This will save you time if
you need to use the value multiple times on the same page.
example:
$heading='';
if (isset($_POST['heading'])) {
$heading=$_POST ['heading'];
}

[PHP] Re: Undefined Index - is this how you declare get post?
settype(), isset(), and empty() checks will all bypass this, but there is no
need to have error reporting set that high ...
error_reporting(2047);

Hi List,
Since I started using error_reporting(E_ALL), I havent found (in my
opinion)
a good way to declare GET and POST variables when getting them from a form
or querystring. I have searched google and the docs for several hours now
without much luck.
?php
error_reporting(E_ALL);
// This line stops the error reporting, else I get - Notice: Undefined
index: i in.
$HTTP_GET_VARS[i]=;
if ($HTTP_GET_VARS[i] == ) {
include(myfile.php);
}
?
Is there a better way?
I have tried var $i (only for classes I've discovered)
settype($i, integer)
Thanks in advance.

What I'm doing wrong?
Undefined index: categorie
if ($_POST['categorie'] == New) {
You're not doing anything wrong. The problem here is that error_reporting
has notices on. The $_POST['categorie'] is not defined.
Change the error_reporting to excluse ERR_NOTICE, or use:
if ( isset( $_POST['categorie'] ) $_POST['categorie'] == 'New' ) }
// Your code here
}

Ealier (other versions of PHP) I have succesfully used the above

Or am I totally wrong?
This was just one example when I'm getting the message Undefined
index or Undefined variable etc. A lot of code which has
previously worked is now giving me loads of headache since I have to
rewrite everything.
Heh, that can be solved by setting the error_reporting in the php.ini to
E_ALL ~E_NOTICE
They can also be disabled by putting the line error_reporting( E_ALL
~E_NOTICE ) at the first (second, after the ?php) line in your code.

You get this error message whenever $_GET doesn't contain anything.
This accects the code shown above.
Ok, am i correct in assuming that it pops this message because $op is not
defined as anything yet?
If so,should i always just do this
$_POST['op'] = '';
$op = $_GET['op'];
switch ( $op )
{
//Code here
}
Or would it be better and more space efficient to do this
$op = isset($_GET['op']);
switch ( $op )
{
//Code here
}
Cause if i do that the Notice Message dissapears for some reason i yet fail
to grab.
This doesn't work since the result of isset($_GET['op']) is either true
or false, not a string value. You need to write it like this:
if (isset($_GET['op']) {
$op = $_GET['op'];
switch ($op)
{
//Code here
}
}
I would really appreciate if somebody could explain to me why the Notice
dissapears when using isset(), and also what is the best method to use
rather then the two shown above?
How do you guysgirls handle this?
