I have a question about your suggestion.
Would it not be easier to simply carry the sessionid from the php session
validation to the javascript?
Instead of: if(document.frmlogin.txtusername.value==)
{
alert(Please Enter Username.);
document.frmlogin.txtusername.focus();
return false;
Why would I want to re-enter the user name?
My common sense which maybe completely wrong say, YOU ARE VALIDATED IN
PHPBB via issetid, now post to (document.frmlogin.userid.value==)
This is why I am not catching your angle.
PhP makes so much more sense. This javascript integration is really giving
me a headache!
Suggestions?

I have been hunting all around that website you referred me too looking

Eh? I never sent you to a website.
See this code:
function validatelogin()
{
if(document.frmlogin.txtusername.value==)
{
alert(Please Enter Username.);
document.frmlogin.txtusername.focus();
return false;
}
if(document.frmlogin.txtpwd.value==)
{
alert(Please Enter Password.);
document.frmlogin.txtpwd.focus();
return false;
}
document.frmlogin.login.value=Success;
document.frmlogin.action=operation.php?mode=login;
return true;
}
You need to create a *similar* function (eg 'BBValidateLogin()') to
check different html field names.
For example:
function BBValidateLogin()
{
var f = document.forms[0];
alert('username is ' + f.username.value);
}
The username.value comes from this:
input type=text class=post
name=username size=25 maxlength=40 value= /
where you have name=username
So take the name=... and put a .value on the end.
Rinse, repeat until you have checked all of the fields you need to.
Return true for the form to submit.
Return false for it to NOT submit.

Hey!
.A little background:
We have a site that has already been made.. a couple of hundred pages displayed
via SMARTY templates, the site's in Swedish.
The navigation and other parts except for the center is taken care of by the
templates and other scripts... the center main text is taken from the
database(mySql) based on $page_id...its in a MySql TEXT field and has all the
html etc that will be displayed in the center of the page.
End of background..
Now they want to add a search function to the site... a simpe textbox where a user
enters a word or sentance and they get 20 results per page... with a x.xx % closest to your
query can anybody give me basic pointers on where to start?
Any links/software or articles too would be appreciated...
http://dev.mysql.com/doc/refman/4.1/en/fulltext-search.html
Start off with that, if they need something more complicated down the
line, revisit.

[PHP] SESSION LOST!
Hi Fellows, I am developing on a large project. Its containing a couple of ajax scripts. One day, my temporeary folder was full, because everytime i clicked some- where in the page, a new session file was created. So i decided, to change to a database driven session management. But it did not really help. Its possible to log into the site. You can do authoring or use the service as it should be, but after a little time, the session is just lost. Sometimes it takes ten minutes, sometimes just a few mouse clicks. Its very strange. But it never happens during the first clicks. Maybe somebody is able to help me.

Re: [PHP] getting $_ENV variables
Thanks Daniel, Greg, Richard,
I made a script with:
?php
print_r($_ENV);

and it results only into: Array ( ) nothing else ...
So it must be caused by a different environment ?
All I want is to check the $_ENV['OS'] within PHP scripts.

Subject: Re: [PHP] getting $_ENV variables
When I print_r($_ENV); from the CLI on 5.0.4 I get a bunch of results, no
problem but no $_ENV['OS'] variable. Further, when I check my phpinfo();
output, there are even fewer $_ENV variables printed than the CLI offers.
I'm not certain about this, Cor, but my guess is that PHP 5.x.x may have
altered the default $_ENV output to hide some of this information --- which is
a good thing, in my opinion, because then you won't just have some
run-of-the-mill script kiddie checking out the details of a box for known
security holes.
Of course, that doesn't necessarily stop ? passthru('uname -a').\n; ?
or checking the $_SERVER['SERVER_SIGNATURE'] variable for the OS
information so perhaps this response is just one of those white-bread
responses. Something to chew on, but you really don't get anything from it.

RE: [PHP] Re: session cookies enabled?
On 09 May 2007 16:36, [EMAIL PROTECTED] wrote: Ford, Mike writes: You can also set up php.ini and use the built-in sessions with http://php.net/session_start so that PHP will take care of this for you. That is what I was intending to do. How do I find out if whether or not the session cookie was accepted using the built-in sessions? I found no function for such a test. Check the SID constant after you've done session_start(). If it has an empty value, the session is using cookies; otherwise, it'll have a value of the form 'sessionname=sessionid', which is what is appended to the URL (or inserted in forms as a hidden value) to propagate the session-id. Interesting idea. This brings up a question. In order to decide whether to use cookies or SID the built-in sessions must be testing to see if the user's browser will accept the session cookies. How do they do that? By sending it out and checking to see whether it comes back on the next page. Assuming your setup is: session.use_cookies = On session.use_only_cookies = Off session.use_trans_sid = On Then the sequence is this: 1. The first page involving a session will *both* send the cookie *and* append the SID to URLs in the page. 2. So the next page request will return the SID, and if cookies are enabled also the cookie. 3. On starting the session for this page, PHP will first look for the cookie: if it's present, its value will be used and SID defined as empty; if not, the browser must not be accepting cookies, so the value from the URL query string is used and SID is defined with the matching string. 4. PHP now knows whether cookies are in use *for this request*, and *either* sends the cookie *or* appends the SID to URLs in the page. 5. Requests from this page will thus *either* return the cookie *or* include the SID as a URL get parameter. 6. Go back to 3. Note that with this setup, you will *always* get at least one request with the SID in the URL. Any site that doesn't do this has use_only_cookies turned on or/and use_trans_sid turned off. If they do it by the 2 page, send a cookie and see if it comes back to the second page method we have been talking about, then somehow, they are sureptiously inserting a forward to a non- existant page! Right? How do they do that? No, see above: they simply wait for the next regular page request to come in and see if the cookie came with it. Nothing surreptitious or super-clever. Cheers!

I've just about finished an ajaxish site but it wasn't fun. A lot of nesting javascript inside php calls, having to write the logic both in javascript and php and so on. The source looks ugly and was time consuming to debug. Thanks! Anything involving javascript development has several built in debugging facilities 1: Alert dialogs: You may find it a chore to learn how to use them effectively. But the current content of any variable can be displayed with an alert dialog. You have to pay attention to how strings are concatenated; with +, The actual variable name cannot be quoted. 2: Browser error reporting, in Netscape species, javascript console. Take a hint, all source code text should be formated for Unix/Linux ( line feed line endings) If you do scripting on a Classic Mac OS = OS9, the line endings are carriage; and Windows uses both carriage return and line feed. return. You will drive your self crazy cussing the console because it will not refer to lines containing syntax errors, but some disrelated lines. 3. View source window in browser to see exactly what the browser is getting on page load. 4. Forms: I have coded special forms just for the sake of development and debug of javascript apps. All globals are visible through out the script, WITH THE EXCEPTION OF SOME THAT ARE DEFINED IN SOURCED JS FILES; Opening a javascript window is in a function does not seem to register if the function is in a sourced file. 5. Patience, patience, patience, some masochism, Several large available paper back text books. No one will describe all you might need to know about issues like rollovers, DHTML, etc, Imagination and ingenuity, or the will to search and sift through others source code until you find what you are looking for, and then making it work for you. That's it, I have some suggestion that there are systems available for javascript but I have done without long enough to have my methods and approaches. One more thing, php and javascript work very well together. I have even written a function to display php variable values as javascript alert dialogs. It will not function as break points for php like it does with javascript, but at least you do not have to decipher php error smeared all over the screen. And Ajax, even though I have not cracked that particular aspect of javascript as yet, looks very worthwhile.

The $_ENV superb-global contains an array of environment settings, so it's not totally baffling that print_r() on it should return an array. The reason it is empty is because the variables_order setting in the php.ini has had it disabled. The default is: variables_order = EGPCS But it must have been changed to: variables_order = GPCS Dropping the E (Environment variables) will cause a print_r($_ENV) to be totally empty. Some hosts do this in order to hide the environment settings because they can contain sensitive information such as the CPU identifiers, etc. I've seen the 'cheaper' hosts (especially those hosting on Windows and/or Virtual Servers) disable this so you can't tell what kind of CPU they're using, or where their system drive is.

The array ($_ENV) exists, it is just the population of it that has been disabled, thus it's empty. Just in the same way that doing a print_r($_GET) will always display an empty array even if the query string is totally blank, or print_r($_POST) does the same, even though you didn't post a thing to the script. The super-globals I guess must just be created at run-time, and populated later on in the process, by which time the php.ini settings have been taken into account and stopped the action.

Within the constructor for Randimg you could set a local protected variable:
class Randimg
{
var $docroot = false;
function Randimg ()
{
$this-docroot = $_SERVER['DOCUMENT_ROOT'];
}
and then you can just reference $this-docroot from any of the Randimg

In PHP 5 could you create $docroot as a protected class constant, but in
PHP 4 the above will have to do.

As Rich pointed out you cannot have constants within a class in PHP4.
To answer the second part of your mail, one technique that I have seen
is something like the code below.
define('FOO_FILE_NOT_FOUND', 1);
define('FOO_FILE_NOT_READABLE', 2);
define('FOO_FILE_INVALID PATH', 2);
class Foo {
function render() {
if (! is_readable(...)) { return FOO_FILE_NOT_READABLE; }
}
}
Another way that is nice is Solar's way of handling locales.
Basically it uses strings such as 'SOME_ERROR_MESSAGE' which is
populated by an include file that contains the actual value to it. So
in this include file you create an array that contains key value pairs
of error codes and error messages.

Ahhh! Very interesting. Many thanks for the code example and explanation
-- that approach works for me.
I assume setting basic strings (i.e. settings) for my error messages
would be best done via:
class Randimg
{
var $msg_1 = 'This is a string';
var $msg_2 = 'This is another string';
function rand_img() { echo $this-msg_1; }
function foo() { echo $this-msg_2; }
}
It just seems so extraneous to declare those strings as vars... A class
constant sounds like the best approach.
I can't wait to start using PHP5! :D
Thanks again Rich! I really appreciate your time and expertise.
Have a great day and/or night.

I don't know if that's the *best* way, personally I'd not really do it
like that, but no-one can tell you it is 'right' or 'wrong' because it
depends on your application. For example if you only have a handful of
possible error messages (say 10) then there is nothing inherently
wrong with the above approach.
If you're talking about lots of error messages then under PHP 4 I'd
declare them as consts in a required() file.
define('APP_ERROR_1', 'This is an error message');
Then just use APP_ERROR_1 in the methods that need it. It's a bit messy
because you are creating consts all over the place, but it's an option
for you and at least it keeps them all in a single file and out of the
header of your class.
Another way might be to create a specific class that does nothing but
handle error messages / responses, then call that.
Cheers,
Rich

Hello all, I'am looking for an WSDL generator class. The aim is to generate an wsdl file to use with the soap extension. The generator will look at the included classes and print all functions (except maybe abstract or private) in a correct xml format. I tried this one which is great : http://www.schlossnagle.org/~george/blog/index.php?/archives/234-WSDL-Generation.htmlbut i have to modify a lot of code and it appears it's not maintained. So what do you do in order to create WSD? Is the soap extension or a PEAR classes will include this kind of function? Thanks Brice

[PHP] scrolling HTML tables
I hope it's not the wrong place to ask, but has anyone experience with scrolling HTML tables ? According http://www.w3schools.com/tags/tag_thead.asp The thead, tfoot and tbody elements enable you to group rows in a table. When you create a table, you might want to have a header row, some rows with data, and a row with totals at bottom. This division enables browsers to support scrolling of table bodies independently of the table header and footer. I don't want to reinvent the wheel in own software. Or is it better to ignore these tags because of bad browser support ? Thanks, Cor

(I've cross posted at the MySQL list as well)
Here's an example with a simple table:
describe collection;
+--+-+--+-
+-++
| Field| Type| Null | Key |
Default | Extra |
+--+-+--+-
+-++
| id | bigint(20) unsigned | | PRI |
NULL| auto_increment |
| receiver_id | bigint(20) unsigned | | MUL |
0 ||
| set_type_id | int(2) unsigned | | |
0 ||
| card_id | int(3) unsigned | | |
0 ||
| completed_set_id | bigint(20) unsigned | | |
0 ||
| created_on_gmt | datetime| | | -00-00
00:00:00 ||
+--+-+--+-
+-++
I want to end up with two PHP arrays. One for set_type_id = 22 and
one for set_type_id=21.
(1) one query method:
SELECT * from collection WHERE set_type_id=22 OR set_type_id=21;
...do query...
while( $row = $this-db-fetch_array_row() ){
if ($row['set_type_id'] == 21){
$array_a[] = $row;
} else {
$array_b[] = $row;
}
}
(2) two query method:
SELECT * from collection WHERE set_type_id=22;
...do query...
while( $row = $this-db-fetch_array_row() ){
$array_a[] = $row;
}
SELECT * from collection WHERE set_type_id=21;
...do query...
while( $row = $this-db-fetch_array_row() ){
$array_b[] = $row;
}
Which method is better? Take a hit using MySQL or take a hit using PHP?

I really don't think you'd notice any difference, unless your table contains
a large amount of data and is not properly indexed. And if that were the
case, you'd notice a hit on just one query anyway.
I'd stick with the 2 query model, but instead of creating arrays, just loop
through the query results to output your data, no sense looping to make an
array when you're just going to end up looping through the array to output;
that seems redundant to me :P
Just my $.02

[PHP] GET variable unexpectedly assigned to session variable
Let's try to make a long story short. I'm writing a (not too complex) system visible to authorized users only. My users are stored in a MySQL database table with usr_id and usr_typ (user type) among other fields. When a user logs in, I retrieve those values from the database and store them into separate session variables: $_SESSION[usr_id] = $rs[usr_id]; $_SESSION[usr_typ] = $rs[usr_typ]; When the user visits a restricted page, I read those session variables to validate the user. So far so good. Problem started when I added a new script named usr_frm.php. This page accepts the user's id and type from the query string, like this: $id = (integer)$HTTP_GET_VARS[id]; $usr_typ = (integer)$HTTP_GET_VARS[typ]; The call comes from a list of users displayed by another script, usr_lst.php, like this (within a loop, of course): print(a href='usr_frm.php?id=.$row[usr_id].typ=.$row[usr_typ].'); Problem is, that, once the page usr_frm.php have been hit, the session variable $_SESSION[usr_type] gets changed (unexpectedly) to exactly the same value passed to the script via GET variable typ. But even worse: this code works perfectly well on my developer machine (Windows) but in doesn't on the actual server (Linux). I realized that the server uses a different PHP configuration, specially: register_globals set to ON. I already got them to change this value to OFF... but this did not solve the problem. I will appreciate any help, suggestion, idea currently I am (honestly) clue less... Thank you in advance. --Armando--.

Re: [PHP] GET variable unexpectedly assigned to session variable
Armando;
First, you can just change these:
$id = (integer)$HTTP_GET_VARS[id];
$usr_typ = (integer)$HTTP_GET_VARS[typ];
to:
$id = $_GET['id'];
$usr_typ = $_GET['typ'];
Second, I see that you're using $row[] variables for your MySQL result
sets but where and how are the $rs[] values populated?

[PHP] PHP sorting csv array output
Hello all, I have a question concerning .CSV array sorting. I have tried googling for an answer and have tried different techniques, but nothing seems to works as I would like it to work. Here is my situation: Test file is located here: http://veanndesign.com/test.php I would like to be able to sort the output by the Time Zone (or any other fields). Here is how my code looks like: http://veanndesign.com/test.html I believe that I need to get all the data from the .csv file dumped into 1 array, and I guess I am struggling at that point. I have tried using foreach inside of the while loop, but it doesn't seem to work. So what is the best and/or right way to sort this type of data? Hopefully, this email makes sense.

Re: [PHP] PHP sorting csv array output
When you load your data into your array, you can use the timezone (or whatever field you're using to sort) as the array key, then use ksort(). Check the see also for a bunch of other types of sorting you can do. When it comes to the multisorts and user defined sorts, I'm at a bit of a loss..hah.. just never had to use them so they're still a bit mystical to me. -TG http://us2.php.net/manual/en/function.ksort.php = = = Original message = = = On 5/10/07, Daniel Brown [EMAIL PROTECTED] wrote: One place to start reading, Anna, would be the PHP manual for the fgetcsv() function, which is specifically for CSV parsing. http://www.php.net/fgetcsv Thanks for your quick reply Daniel.

[PHP] sqlite if query changes to empty on a loop
Hello,
I have a loop on an sqlite query which checks $domain until the status of

However when all the $domain items have been deleted I need the script to
stop.. regardless of how many querys the loop
still has to run. So I want to detect when its empty and then stop.
I have this... which does not work.

$db = sqlite_open(whois.sqlite);
$x = 0;
while ($x 9000) {
$result = sqlite_query($db, SELECT * FROM whois ORDER BY id);
// if (!$result) {
if (empty($result)) {
echo No data;
} else {
while ($row = sqlite_fetch_array($result)) {
$domain = $row['name'];
echo $domain;
$x++;
usleep(40);
}
}

[PHP] PHP MySQL
Hi Everyone,
I know this isn't strictly a PHP question, and I apologize in advance
for that. I'm trying to setup a website for some of my customers that
would allow them to update a database on their schedule, making it
easier for us to have the most up to date info, and taking some of
the work off of us.
Right now, the question I have is, how would I be able to select
certain records to be deleted (Or moved to another table called
deleted)? Is it as simple as looping through the database, having
them check a checkbox, and then hit a remove button?
As I go, I will be adding a login screen to it, and hopefully
protecting against SQL injection attacks... But right now, I'm still
just learning and trying.
The SQL syntax is easy enough for me to figure out, but the php is
throwing me off right now...
I'm running PHP 5.2.0
MySQL 5.0.24A
Any points to the right documents are greatly appreciated as well as
sample code :)
Currently here is the code I'm working with on the page to display it:
$link = mysql_connect($server, $username, $password)
or die('Could not connect: ' . mysql_error());
echo 'Connected successfully BR';
mysql_select_db('legion') or die('Could not select database' .
mysql_error());
echo 'DB selected BR';
$result = mysql_query(SELECT * FROM current) or die(mysql_error());
while($row = mysql_fetch_array($result)) {
$FName = $row[FName];
$LName = $row[LName];
$Add1 = $row[Add1];
$Add2 = $row[Add2];
$City = $row[City];
$State = $row[State];
$Zip = $row[Zip];
$Date = $row[Date];
echo $FName, $LName, $Add1, $Add2, $City, $State, $Zip, $DateBR;
};
I'm sure there is an easier way to do that as well... But this way
worked :)

I don't know WSDL - at all - don't want to know it -- shouldn't have to know it. Grrr. Sadly I had the same frustrating experience you did and ultimately ended up using this WSDL_Gen tool too. What do you have to modify? It worked fine for me for int, float, string, and array -- although it's kinda wonkey with a hash as it turns it into an array -- well something does. G. Not sure if that's a SOAP feature or a bug or what. All the other solutions (for lack of a better term) required just as much messaging to even get going. WSDL_Gen was quick and dirty and got my app up and running in a few hours. We use Ruby to talk to PHP5 via SOAP.

return $this-method_foo($foo1, $foo2, $foo3);
}
function method_foo($x, $y, $z) {
/* Do stuff... */
return $x.$y.$z;
}
}
Hopefully my syntax is decent... I am guessing the approach I take
depends on the needs of my script. Setting local protected variables
seems like it would work well for my latest project, but is that bad
programming practice to rely upon local protected variables when it
comes to passing variables between methods?
Seems like I have always read/heard that it is best to explicitly pass
variables as function parameters... vs throwing around globals.
Sorry if silly questions. :)
Thanks again!
Cheers,

[PHP] reading private properties (print_r)
Hi, I dislike the output of print_r(), so I desited write my own print_r(). I need this funktion for debugging issues, and therfor it is nice to have the private attributs, which are normaly hidden. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] What is the best way to protect the PHP page that returns the AJAX data?
Like most sites, someone needs to join up to use mine. I'm using a wee-bit-o-AJAX to pull some results from a database and display them dynamically. For the AJAX to work, it has to hit a script that's accessible from the htdocs tree right? Effectively it's just a (JavaScript initiated) GET URL request correct? For example, index.html calls http://example.com/gimmedata.php?query=foo That in turn returns a JS formatted array which is eval() in JS and rendered on the page. (over simplified I know) My question is, how do you protect gimmedata.php since it's sitting out there sans normal web headers and stuff? Can it include session_start() and do all that wonderful checking to make sure the user is logged in before just happily doling out my precious data? What is the proper, secure, sanctioned and AJAX/PHP blessed way to do this? I could set up a test environment and hack up something I'm sure -- and probably will if I get too impatient, but nobody seems to address this issue in any examples, they just do it as if information is *gasp* free. I'm a PHP guru, but I am also an AJAX novice. From what I gather, the return is really in XML transport format and all the magic of converting to/from XML is transparent to me. I worry that putting other headers or whatever may corrupt that? -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Ah, well Chapter 6, page 144-145 have helped clear-up a little bit of my
confusion:
...snip...
Here's a simple class definition of the Person class that shows the
$this variable in action:
class Person {
var $name;
function get_name() {
return $this-name;
}
function set_name($new_name) {
$this-name = $new_name;
}
}
As you can see, the get_name() and set_name() methods use $this to
access and set the $name property of the current object.
...snip...
Declaring Properties
In the previous definition of the Person class, we explicityly declared
the $name property. Property declaration are optional and are simply a
courtesy to whoever maintains your program. It's good PHP style to
declare your properties, but you can add new properties at any time.
...snip...
You can assign default values to properties, but those default values
must be simple constants:
var $name = 'J Doe'; // Works
var $age = 0; // Works
var $day = 60*60*60; // Doesn't work.
...snip...
So, I think I was getting a bit confused with the var variables... But
now it looks like it is not bad practice to get and set object
properties, and it almost sounds like it is good practice (though, not
required) to declare these properties (var variables) for other
eyeballs/programmers.
Man, I love programming in PHP. I just wish I were better at it! :D
K, gonna go practice some on these new techniques.
Cheers,
Micky

Re: [PHP] sorting via PHP or MySQL?
A somewhat more extensible version of the 1 query method:
http://www.garfieldtech.com/blog/php-group-by
If you will only ever have 2 values there, then either method is probably
fine. The php group by method (above) is more extensible if you're going
to have a variable or arbitrary number of groups, though.
Cheers.

I want to end up with two PHP arrays. One for set_type_id = 22 and
one for set_type_id=21.
(1) one query method:
SELECT * from collection WHERE set_type_id=22 OR set_type_id=21;
...do query...
while( $row = $this-db-fetch_array_row() ){
if ($row['set_type_id'] == 21){
$array_a[] = $row;
} else {
$array_b[] = $row;
}
}
(2) two query method:
SELECT * from collection WHERE set_type_id=22;
...do query...
while( $row = $this-db-fetch_array_row() ){
$array_a[] = $row;
}
SELECT * from collection WHERE set_type_id=21;
...do query...
while( $row = $this-db-fetch_array_row() ){
$array_b[] = $row;
}
Which method is better? Take a hit using MySQL or take a hit using PHP?

RE: [PHP] What is the best way to protect the PHP page that returns the AJAX data? [solved]
Thanks for the suggestion and concern. Fear not, I'm a PHP Guru as mentioned. I
never said that I execute the code directly like
that. Perhaps my query keyname was a bit misleading. Would
http://example.com/gimmedata.php?id=3foo=barmap=on have been more
clear? I also am not so silly as to run unchecked variables into my SQL
queries, nor do I not check for mismatched ' ; and other
injection attempts in my database wrapper. ;-)
Anyways none of that is the point. I wanted to know how to prevent a random
person from hitting that same gimmedata.php using their
own parameters (valid or not)
Since I wrote this initial email, I've done some testing, and much to my glee,
it seems they work just like any other page, so
therefore putting a simple session_start() and testing if the user is logged
in, etc is quite effective.
