The following is just to build a select menu from a table query result
set.
It sort of works, but doesn't return the first row in the result set,
ie if
I have the following rows in the table 'cats';
id title
==========
1 Pears
2 Oranges
3 Apples
4 Bananas
echo "<select name=\"cats\">";
$result = mysql_query("select * from cats order by title");

The resulting select menu will only include Bananas, Oranges, Pears.
Am I missing something terribly obvious to one less newbie than me?

on index.php, are you including directly the file passed by content?
if you are vulnerable, the autor of your index.php is the one to blame,
not php hehe
if safe mode is on, you may be immune to this asu.txt, but dont relly on
it against everything else that can be done

I need to use PHP to pull the first page from a Word Document and then
print it to the screen. It doesnt have to be fancy, so even if just the
text is pulled that would be fine (although formatting would be grand
too).
Anyone got any ideas? I cant use the COM object since Im running this on a
linux machine, and I have limited access to installation of 3rd party
software because I am using shared hosting. Classes would rock, or
anything really.
I was thinking about converting it to text somehow, and then just pulling
the first 50 lines or so - but I dont know how to convert it to text...
What do you all think?

Here is a snippet of sample code I have that uses wvWare[1] to display a
Word doc. You should be able to pass it through shell_exec[2]. It is
not perfect but does a decent job of keeping formatting.
passthru(WV_HTML_PATH . ' "' . FILES_HOME_DIR . $file . '" -');

Try $_SERVER['REMOTE_HOST']
Also, if apache is not configured with HostnameLookups On this won't be
set. You can get the IP from: $_SERVER['REMOTE_ADDR']

You're right, the addr is what I really want, and
_SERVER["REMOTE_ADDR"] works, but when I tried the _SERVER["REMOTE_HOST"],
it is still empty, so my web host must HostnameLookups OFF. Problem solved,
and "thanks" to all!

Hello,
the following code shows my problem:
<?php
class MyElement extends DomElement {
function __construct($name) {
parent::__construct($name);
}
}
$doc = new DomDocument();
$node = new MyElement("test");
$node = $doc->appendChild($node);
$node->setAttribute("xmlns", "http://www.somedomain.de/";);
print("Namespace: '" . $node->namespaceURI . "'");
$xmlCode = $doc->saveXML();
print("<pre>" . htmlspecialchars($xmlCode) . "</pre>");
?>
the output would be:
> Namespace: ''
> <?xml version="1.0"?>
> <test xmlns="http://www.somedomain.de/"/>
As you can see it is impossible to set the namespace manually! I tried to
set it with the help of a DomNamespaceNode-object but those objects are no
"real" nodes (why!?!) and the consequence is that you couldn't append such
a node with $node->appendChild($domnamspacenode_object); ...
Further it isn't possible to use the function $doc->createElementNS(...)
because this function returns a domelement-object but i want the element to
be my own MyElement-object.
So how to get a namespace in my node???
thanks in advance,
vivi

I am not sure if PHP 5 has many changes from PHP 4, however have you
tried calling set_namespace[1]?
$node->set_namespace('http://www.somedomain.de/');

PHP Newbie,
I'm trying to find out if a username already appears in my database.
I have two users in my table, one is colin so when I enter a username of
colin I would normally under ColdFusion anyway just to something like:
<cfif $query_qUsername.RecordCount GT 0>
User already exists do something else, like throw the user back an error.
</cfif>
My Query works
$query_qUsername = "SELECT * FROM users WHERE username = '$username'";
I've tried a number of different things here and everything either comes
back with nothing, or throws an error.
$num_rows = mysql_num_rows($query_qUsername);
echo $num_rows; // this comes back with nothing, I was expecting a numeric
of 1

Hi,
Do a select query with a COUNT() in it....
if you dont understand that read the php manual for accessing the database
and lookup the mysql COUNT

First, consider echo $query_qUsername to ensure that it contains what you
think it does. Second, consider using mysql_error() after your call to the
database to show the text of any error returned by mysql.

$query_qUsername is a String
mysql_num_rows want a result resource as argument
You have no result till you do mysql_query

Andre,
Thank you, I had read the manual, understanding it fully when you've been
coding in another language is another matter.
I had relied on DreamweaverMX to create the Database connection which meant
I didn't really understand how it was returning the results.
I was able to output the results by altering the code DreamweaverMX had
created.
Thanks, now using the database query method you showed, I've been able to
get the number of rows returned.
However, whenever I change the username I still get a row count of 1 ?
<?php
if (isset($_POST["USERNAME"])) {
$username = $_POST["USERNAME"];
$result = mysql_query("SELECT count(uid) FROM users WHERE username =
'$username'")
or die("Invalid query: " . mysql_error());
$num_rows = mysql_num_rows($result);
echo $username ." \n". $num_rows;
}
?>
echo $username
returns the username entered into the field before the submit button is hit.
$num_rows;
always returns one numeric 1 even though there is no username like $username
in the database ??????
Have I missed something?

i think the query: "SELECT count(uid) FROM users WHERE
username='$username'", will give a one row result, that row will have
one field, and that field is the number of rows that match the where
clause (you are using count(uid))
if there is no match, the result will be a row, with a field, with 0 as
value
mysql_num_rows return the number of rows of the given result
you can do this:
$result = mysql_query("SELECT count(uid) FROM users WHERE username = '$username'")
> or die("Invalid query: " . mysql_error());
$num_rows = mysql_result($result, 0, 0);
or this:
$result = mysql_query("SELECT uid FROM users WHERE username = '$username'")
> or die("Invalid query: " . mysql_error());
$num_rows = mysql_num_rows($result);
i think the first one is better

You will need to build php yourself, take a look at configure --help:

Hi folks. I'm wondering if anyone out there can point me in the
direction of a good tutorial/article on how to implement authentication
using Kerberos in a PHP application running on Apache 2.0.
I've googled and searched the lists but I can't find any tutorials or
articles which fully explain this.
Does anyone have any suggestions?

hi!
i'd like to redirect a person to another page but after a certain time interval
has elapsed. this is because i have a generic error displaying page and i would
like the person to go to this page, stay there for like 10 seconds and then be
redirected to the index page.
i was using header("url") to redirect the user.
but how do i get that to happen after a certain time interval.

You can't view the page and have PHP redirect it. You would need to use a

You can sleep() the script, but no output will be sent to the browser.
If you want them to view the 'error' page, ie output to the browser for
the user to read, you cannot use php to redirect them after that. Use
JavaScript. PHP == ServerSide, JavaScript == ClientSide.

hi!
i have a login page that after validating the login and passwords does something
like
// initiate a session
session_start();
// register some session variables
session_register("SESSION");
// including the username
session_register("SESSION_UNAME");
$SESSION_UNAME = $login;
// redirect to protected page
header("Location:manager.php");
when i try to run this at home with my apache 1.3.27 i get the following errors:
Warning: session_start() [function.session-start]:

make a directory on your C drive called Temp than set the php.ini
setting as
session.save_path = "C:\Temp"/tmp

I am not sure if PHP 5 has many changes from PHP 4, however have you

Vivian, it's not possible the set the namespace according to the W3C
standard, except with createElementNS(). As Adam said, in PHP 4, there
was the option set_namespace, which isn't ported to PHP5 (yet).
Maybe we should port that function as well, to allow some deeper level
manipulation of the namespaces...
Currently, I don't have a solution to your problem, except porting
setNamespace to PHP5...

Porting the setNamespace function to PHP5 would be nice. Another solution
could be the possibility to append a namespace-node (is the
domnamespacenode class currently used by any functions?) or the
setAttribute checks wether some "xmlns"/"xmlns:" attribute is set and
updates namespaceUri itself... would be more W3C standard compliant.
without the functionality to set the namespace it will never be possible to
overwrite the createElementNS of domdocument, as the following example
shows:
<?
class MyElement extends DomElement {...}
class MyDocument extends DomDocument {
function createElement($name, ...) {
$element = new MyElement($name, ...);
return $element;
}
function createElementNS($uri, $name, ...) {
$element = new MyElement();
// here you should set the Namespace...
// ...unfortunatly impossible
// that would be nice
$element->setNamespace("http://...";);
// -> maybe you get into trouble with "NO MODIFICATION ALLOWED
ERROR"!!
// because node isn't appended
// or something like
$element->setAttributeNS("http://www.w3c.org/2000/xmlns";,
"xmlns",
"http://mydomain.de/";);
// -> maybe you get into trouble with "NO MODIFICATION ALLOWED
ERROR"!!
// because node isn't appended
return $element;
}
}
?>
i think because of the problems with the MODIFICATION ERRORS while node
isn't appended, it would be best if you could define the node-namespace
with the third argument of DomElement::__construct($name, $value, $uri =
"defaultUri")...
it would be VERY nice if you think about such solutions...
thanks a lot,

JW> What is horrible about that style? IMO doing this:
Consistency. The majority of code you can download will not use this
notation. Although PHP coding standards are subjective as best, you
still won't find any advocating this technique. Pick a style and stick
to it. It's usually best if that style at least matches something like
the official PHP documentation.

To me this is a mess and I would never advocate this style. Code on
the same line as a php delimiter does not make for easy reading.

I wouldn't have done it like that either, although its closer.
<?php

{
...
}
?>

Of course it does, especially when combined with the other factors I
listed. If the book you're learning from doesn't teach good coding
practise - what will? It's not something you're "born" with.
