Should work here ...
Since the call below is ADDING to $xml you do need something existing 
to add to so what does that give?

Thanks Lester, that worked. I had just put that in the wrong place.

So basically, $xml is out of scope for this function and you are appending
to a nonexisting variable?

$xml is defined in other functions, just not in this function. $pos is 
irrelevant to the question - it is just the string position within the

Your email client is annoying, it doesn't quote.  Haha.

Anyway, so, you're loading up that array with arrays of arrays, here:

   1.
  $position = 1;
   2.

   3.
  while ($row = mysql_fetch_array
  
($result))
   4.
{
   5.
$_SESSION['fullRestaurantList'][$position] = $row;
   6.
$position++;
   7.
}
   8.

   9.
$_SESSION['totalNumberOfRestaurants'] = $position;

So, if you get 7 rows.  Your array will have:

Array => (Row 1 Data)
Array => (Row 2 Data)

.. etc

You do not have ['fullRestaurantList']['ID'].  In the page you're
referencing you use something like
$_SESSION['fullRestaurantList'][$i]['SomeValue'].  I assume $i is the
"Position" in the array, so you likely want to use
$_SESSION['fullRestaurantList'][$i]['ID'] to get the ID field from that row.

If you need a quick dump to better understand what data you have in your
session, try making a page called session_dump.php in the same directory
with this source:



That will give you a good idea of what your session array looks like,
and you should see clearly that ['fullRestaurantList']['ID'] does not exist.

Hope this helps!

So then you'll use mod_rewrite, since Apache needs to tell PHP how
to parse it.  Otherwise, Apache is going to be looking for /test/mail.

#.htaccess:
#
Options -MultiViews

RewriteEngine On

#
## Redirect to remove trailing slashes on extensionless URL requests
# If requested URL ending with slash does not resolve to an existing
directory
RewriteCond %{REQUEST_FILENAME} !-d

#  externally redirect to remove trailing slash.
RewriteRule ^(.+)/$ /index.php?s=$1 [QSA,L]


#
## Externally redirect clients directly requesting .php page URIs to
extensionless URIs
# If client request header contains php file extension
RewriteCond %{THE_REQUEST} ^[A-Z]{3,9}\ /[^.]+\.php\ HTTP

# externally redirect to extensionless URI.
RewriteRule ^([^.]+)\.php$ /index.php?s=$1 [QSA,R=301,L]


#
## Internally rewrite extensionless file requests to .php files ##
# If the requested URI does not contain a period in the final path-part
RewriteCond %{REQUEST_URI} !(\.[^./]+)$

#  and if it does not exist as a directory
RewriteCond %{REQUEST_FILENAME} !-d

#  and if it does not exist as a file
RewriteCond %{REQUEST_FILENAME} !-f

#  then add .php to get the actual filename.
RewriteRule (.+) /index.php?s=$1 [QSA,L]

# End .htaccess


You can figure out the rest yourself.  ;-P

Are you sure it's an array? Use print_r() or var_dump() on

could do this too:

$_SERVER['REQUEST_URI'] = 'It/Works';

   Well, that wouldn't address the issue of the code he gave on the

$_SERVER['REQUEST_URI'] into an array with explode() if it contains a
forward-slash ("/").

   What would be better in that case would be:

 0 ?
explode('/',$_SERVER['REQUEST_URI']) : $_SERVER['REQUEST_URI'];

if(is_array($data)) {
   // Handle as appropriate.
}

   However, that's not the best option as:

   1.) REQUEST_URI may not (though it should) have *any* forward
slashes in the URI passed to PHP by the HTTP server.
   2.) It leaves too much other stuff to be done.

   Instead, check out:





I'm not positive that does exactly what I want... What I'm really  
going for is given this URL:


purl.mysupersite.com/test/mail

"test" refers to a record in the database.
"mail" refers to a file on the server which is included when "mail" is  
present. Otherwise the main page is used.

actually at that point it's not an array... it's just loading

[PHP] Undefined index error

[Jason Pruim]

So sometimes I end up with issues that are so simple I should be able  
to fix it but for some reason I end up asking a stupid question to  
the list... So... Here goes :)


Here is the error:

Notice: Undefined index: 2 in /home/raosetc/public_html/purl/p.php on  
line 19


and here is Line 19:

$data = explode("/", $_SERVER['REQUEST_URI']);


When you first hit the site you to go something like:  
purl.mysupersite.com/YourNameHere


If you went to: purl.mysupersite.com/YourNameHere/ (Notice the  
trailing /) there would be no error...


Now I know it's just a undefined index error and I can safely ignore  
it since it works just fine. All I have to do is turn off the error  
reporting and it's gone... But I want to write good code...


Any Suggestions?

The isset function does not give an error if you pass it a non-existant 
variable. Are you sure it's this line that's causing the undefined index 
error?

If you use something like:
$_POST['password']
$_COOKIE['password'] // this is a REALLY Bad Idea
$_GET['password'] //bad idea
$_SESSION['password']
.
.
.

but you don't actually *HAVE* a 'password' in the array, then you will
get that error message.

Your assumption that you have some kind of password is invalid.

Check first:

if (isset($whatever['password'])){
  //rest of your code in here.

Yes, you're probably trying to get a value from an array by using a
key that isn't in the array.
Something like this:
 "test", "foo"=>"bar");
$value = $array['password']; // Key "password" doesn't exist!
?>

Check the line number and print out the array with var_dump/print_r to
see what's in the array..

[PHP] Undefined index error

[Christian Cantrell]

I'm getting this error in my Apache log file, and I can't figure out why:

Undefined index:  password in /path/to/file.php on line 82

Some searching on Google turned up a bunch of questions, but no answers.
Any idea what this warning message is referring to?

This bit of code is getting run BEFORE the submit button has been
pressed.

In that case, $_POST itself is not defined, much less $_POST['heading']

You really shouldn't be stuffing values into $_POST.  Think of it as a
read-only variable that the browser sends TO you.

Here are some options:

OPTION 1:


OPTION 2:


Some people think the ternary operator is "confusing" or "obscure" or
whatever.  Others think it's a perfectly natural operator.  YMMV

[PHP] undefined index and php

[Ross]

Before someone advises me to 'google' my question. I have and can't find a 
PHP.net example either.

I have turned off registered globals and am updating my scripts so they work 
but I keep getting an undefined index problem using $_POST

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..

Probably because $quantity IS 0, then the vars used in the else {} is
never set, but still in the script.

Try setting these before the if statement:

$pieces = array(); 
$formatted_price = 0;
$pricecode = 0; // this one is never set? Or set earlier in the script?

The trouble is I get a NOTICE that tells me the indexes 1 to 4 have not been

What is the output of:

Hmm. upload_tmp_dir was unset. The php.ini says that in this case the
systems default tempoary directory is used. So I guessed it would be
/tmp, because php also saves the session data there. Now I set the
upload_tmp_dir explicit to /tmp and it works.

So where on linux systems is the default tempoary directory set?

I would not recommend turning down the error reporting level. This might
lead to unexpected behaviour in your application and makes it hard to back
track errors.

Always develop with error reporting set to E_ALL. You may set a lower level
for your production environment and disable the display of errors:
ini_set('display_errors', 0);

That's not an error.  Three ways to solve this...
1)  Turn down your error reporting level.
2)  Declare your variables before using them
$_SESSION['user_status'] = NULL;
echo ( $_SESSION['user_status'] );
3)  Code for variables that may not exist
if ( isset ( $_SESSION['user_status'] ) ) {
echo ( $_SESSION['user_status'] );

Or any combination of the three.

I have a form which call a php file when click on the submit button :



First this runs correctly when i click on the submit buttom then the file 
recherche.php is executed and the result is displayed.
I modify the design of my pages in order to display result into frames. So i create a 
frameset named recherche.php which contains
two frames "rech_haut.php" and "rech_bas.php".

And when i click on buttom submit in order to display the result i have this notice 
message : 

Undefined index: numcpte in c:\inetpub\wwwroot\rech_haut.php on line 66

For information, i have not this error when the file recherche.php is a simple file 
without frames !!!

Adjust your error_reporting() level so these notices don't show up.

If you know which variables are required per 'function' that is being
called wrap an if around these variable declarations in blocks.  You
will still have ifs, but you should have a lot fewer.  If by function
you mean actual functions then you could move these lines to the top of
their respective functions.

You can either:

1. put @ in front of each variable, e.g.
$adminID = @$_ENV['HTTP_REMOTE_USER'];
2. change your error reporting level:
error_reporting(E_ALL ^ E_NOTICE);

[PHP] Undefined index???

[irinchiang]

Hi all, 

I keep getting this error:

Notice: Undefined index: tutor_id in /usr/local/..

What does "undefined index" exactly mean?? I did a search on the web but 
couldn't find any solutions. 

The line that cause this error is as follow:

$tutor_id = $_POST["tutor_id"];

.
.
.
.if($action == "edit")
{
$sql = mysql_query ("SELECT * FROM tutor WHERE tutor_id='$tutor_id'");

$row = mysql_fetch_array($sql);

etc.

Hope to get some help here soon...thanks in advance.

Thanks in advance.

isset() is your friend.

if(isset($HTTP_GET_VARS['i']) && $HTTP_GET_VARS['i'] == '')
{ include('myfile.php'); }
This will not trigger any warning, even under E_ALL.

In response to some of the other posts, developing at E_ALL is a good 
idea as it'll help you spot potential problem areas.

Also, even though you have a form element defined, it may not always 
appear in $HTTP_GET_VARS/$_GET (post, etc). One example are checkboxes. 
If no boxes are checked, the variable is never created and this is the 
way to check.

error_reporting(E_ALL) tells me that I have an indefined index, but as Jon
Kriek pointed out,
perhaps reporting "all" the errors is not such a "good thing".

Why would you want to declare a GET or POST variable in the first place?
You'd be overwriting whatever value was stored from the form.

Also, depending on your version of PHP you should be using $_GET and
$_POST and not $HTTP_GET_VARS or $HTTP_POST_VARS.

These are not errors, but notices, you can get around it using:
if(isset($i) && array_key_exists($GLOBALS, $i)) echo $GLOBALS[$i];

or you might prefer setting error_reporting to not display notices

[PHP] undefined index....property.

[Bruce Levick]

I have just setup my localmachine to see how our site runs on php 4.2.
It currently runs on 4.1 on the server. I am only fairly new to this so
I have come across a slight hurdle.

At first logging in as a user to the database was giving "undefined
variable" error. Have read up on this and fixed it by turning on
register_globals. So that's sweet. Although my other form page is for
joining up, which sends variables to another page and then in turn sends
the info to the database. The info that the user fills out gets passed
ok cept  I get two errors output to the page.

//filled out info and clicked send.

Notice: Undefined index: license in c:\inetpub\wwwroot\php\config.php on
line 51

Notice: Undefined property: num_rows in
c:\inetpub\wwwroot\php\adcjoin.php on line 67


//

This is my action on the submit page






The undefined property is in the
adcjoinpage.php

$db->query("SELECT Username FROM global WHERE
(Username='".$Username."')");

if ($db->num_rows>0){

array_push($error,"Choose another username, this
name is reserved\n");

$flag = 1;

}


///attatched to adcjoin.php

require("connect.php");


//
Config file called on by connect.php contains a license variable.
//

I Am not quite sure why it is outputting these two errors. I have not
changed anything from downloading it off the serverapart from
targeting the database on my local machine now. Is it possibly a session
error??

If anybody has any thoughts please pass them on.

Cheers Bruce

[PHP] Undefined index, Undefined variable, Undefined constant....

[Jens Winberg]

I'm having trouble with the newest version of PHP (4.2.2).
For example in a page I'm using the following code:
if ($_GET['action'] == "logout") {
   //do something
}

But I'm getting an error message that says:
...log_message reports: PHP Notice:  Undefined index:  action in

Ealier (other versions of PHP) I have succesfully used the above code, but do 
I now have to rewrite the code like this:
if (isset($_GET['action']) AND $_GET['action'] == "logout") {
   //do something
}

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.

Please, I need some help.

Re: [PHP] Undefined index error

[Michael Sweeney]

If you try to access a form variable that hasn't been set, you get an
undefined index. Try checking with something like 
if(isset($_POST['SortBy'])) {
   // do something with 'SortBy'
}

In any case, you'll get the undefined index warning anytime you try to
read an array index that hasn't been set.

[PHP] Undefined index error

[Shu Chow]

I'm using the superglobal $_POST array to access URL 
parameters passed to my page. I was getting undefined 
constant errors in my error_log file, and found that I 
needed to quote the variables in the array. 
  $_POST['SortBy'] etc. Now, it appears that I've just 
traded the undefined constant errors for undefined index 
warnings. Everytime a page hits a page with url 
parameters, it triggers a warning in the error_log file. 
What's triggering these undefined index errors? I suppose 
I could lower the logging level in php.ini, but I'd rather 
code properly than to hide the problem. Thanks!

If there is not a get variable in the url you will get the warning.

If there is not a get variable callled "op" you should still get the 
warning.

Now $op will be a boolean assigned the value true (if there is a get 
variable called "op" in the url) or false if not. As $op will have a 
value then there is no warning.

What I tend to do when I have an optional item of data is:

if (isset($_GET["op"])) [
$op = $_GET["op"];
}
else
{
$op = "no value";// set to something you can test for in 
your switch statement.
}
though there may be a better way.

[PHP] Undefined Index

[Jürgen]

It's me again, i don't mean to be a bugger, but i really like to learn as
much as possible, that's why i ask (or will ask so many questions).

Consider the following (i shortened this a lot, but it will do the trick)

$op = $_GET['op'];
switch ( $op )
{
 case "admin":
  DoLogin();
  break;

 default:
  ShowHomepage();
  break;
}

PHP shoots a Notice Message telling me that there is an undefined index
Undefined index: act in g:\apache_web\intern\looney\index.php on line 177

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.
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 guys&girls handle this?

Thanks a lot in advance for your time and patience!

Best regards from Vienna,
Jürgen

RE: [PHP] Undefined index?

[Philip Olson]

If one has :

  $arr = array('a','b','c');

And calls upon the following :

  $arr[b]   (as opposed to $arr['b'])

Then the following will result :

Warning: Use of undefined constant b - assumed 'b' in ./tmp.php on line 13
Warning: Undefined index: b in ./tmp.php on line 13

Always use quotes around the keys/indexes within associative arrays
otherwise the constant is looked for first and unexpected results are
possible.  Now if we have (which you most likely did) :

  $arr['d']

Then we get the following as index 'd' does not exist within the array :

Warning: Undefined index: d in ./tmp.php on line 13

A similar error is created when doing this :

  echo $iamnotset;

  if ($iamnotset) {

Which results in :

Warning: Undefined variable: iamnotset in ./tmp.php on line 11

Using something similar to isset() helps combat that :

  if (isset($iamnotset)) {


All of the above errors (Notices) are of the E_NOTICE type.  If E_NOTICE
is turned on within the error_reporting setting within php.ini (or via a
call to the error_reporting() function or ...), then you'll see it
otherwise you will not.  I'm not sure why Notices say "Warning: ..." but
they do :-)

Typically one turns errors up during development, and down during
production use.  And, it's not uncommon to see this question come about
within various support forums/lists for various PHP applications.

Regards,
Philip

RE: [PHP] Undefined index?

[Adrian Ciutureanu]

If I know well, "Undefined index" is a warning, not an error.
If you have
error_reporting = E_ALL
in php.ini (not error_reporting = E_ALL & ~E_NOTICE)
$a = array('a' => 'xxx', 'b' => 'yyy');
and you try to access $a['c'], then PHP will report that you are trying
to access an undefined index array.
