PDF Issues In IE
im having issue opening pdf's in IE, im basicly outputting a pdf to a browser by reading the file in then printing it out. The headers set are

header('Content-Type: application/pdf');
header('Content-Length: '.$file_size);
header('Content-Disposition: inline; filename="document.pdf"');

now this works fine on the local server in both IE and Firefox, however when i try and put it on the live server IE just asks wether i want to open or save "Adobe Acrobat Control for ActiveX". It works fine in firefox.

the headers sent on the live server show as

HTTP/1.0 200 OK
Date: Fri, 22 Dec 2006 12:11:25 GMT
Server: Apache/1.3.33 (Unix)
Cache-Control: no-store, no-cache, must-revalidate, post-check=0, pre-check=0
Content-Disposition: inline; filename="document.pdf"

Pragma: no-cache
X-Powered-By: PHP/4.4.4
Content-Length: 229287

has anyone come accross the same problem and possibly a soloution?

Php 4/5 Issues
I'm building a website, and I've been using Php 5 on my computer. I found out, however, that my hosting company still uses php 4. I uploaded my php files anyway, and they don't seem to be working. Does anyone know a good place to find what in my Php files may not be compatible with Php 4?

Legal Issues With Php ?
I made a commercial application using php and mysql database. Now i am interested in legal issues regarding commercial distribution of that software. I intend to sell that php code (distribute my .php files only). As I understand, it is free to me, right ? Meaning php+mysql are free to use, I do not have to pay fees to authors of php and mysql ? Can you direct me to read some more articles on legal issues, or anything I need to know before selling my softweare?

Issues With Mail()
I basically wrote an auto emailer that will send a welcome email to a new user and then update the db to say that the mail had been sent in order to avoid sending a million emails.

The problem is this.. mail() doesn't always return true when an email has been sent successfully... I know this because I tested it on myself a number of times last night. In faact, I am not sure the mail() function has ever returned true after a successful exicution.

Now I really have no idea if the emails are being sent of not since the mail() function returns false all the time and I know that atleast some of the time mail is being sent but I can not be certain that it is always being sent due to mail() returning false.

Having Some Date Issues
I'm creating a "power rankings" page and I have the database set up like this:

rank_id ¦ date ¦ player_id ¦ rank

I list each player and rank with the date (8 in total for each week).

I can get current rankings (or archived rank if viewing old rankings) with no problem. The problem I have is when I try to view the previous rank. I can't get the previous week to the one I'm viewing to work.

this is the code I current have. I need to change the "Get previous power8 date" section so that it gives me the date prior to either the current date, or the date given in the url.

//Get current power8 date
if(!empty($_GET)){
$current_power8 = $_GET['date'];
} else {
$query_current = "SELECT date
FROM power8
GROUP BY date
ORDER BY date DESC
LIMIT 0,1";
$current = mysql_query($query_current, $connectDB) or die(mysql_error());
$row_current = mysql_fetch_assoc($current);
$current_power8 = $row_current['date'];
}

//Get previous power8 date
$query_previous = "SELECT date
FROM power8
GROUP BY date
ORDER BY date DESC
WHERE date < $current_power8
LIMIT 0,1";
$previous = mysql_query($query_previous, $connectDB) or die(mysql_error());
$row_previous = mysql_fetch_assoc($previous);
$previous_power8 = $row_previous['date'];

I get an error with this: "WHERE date < $current_power8"

What can I do differently?

Security Issues?
I'm new to PHP but have read enough to know to ask the experts before implementing anything. I want to allow non-registered visitors to submit data via a form. That data would not be immediately viewable on the website (I would review and edit before adding the data to the rotation). The visitor would get a 'thank you' page upon submission (no posted data displayed back to them). Is there any danger to my database in allowing just text to be inserted? In other words, are there malicious things that malicious people could do with a text form? I'm not allowing image or file uploads or anything else.

Upgrade To 4.3.10 Issues?
I got an email from my web host stating that they are going to upgrade
their PHP on the server from 4.3.8 to 4.3.10.

Are there any known problems with this upgrade that need to be addressed
in the PHP scripts I use? I'm sure there will always be some small
glitches in an upgrade like this but I'm looking for any info on the
scale of any "register globals = off" type changes.

Authentication Issues
Well not exactly authentication issues, i am having an issue that is driving me crazy. On my page's index i have three frames. One frame for the top (banners and such), a left frame (for navigation), and a right frame for the body of the site. My problem is that in the left frame I have a php script to determine whether someone's logged in or not (using cookies).

If the person is not logged in, the table displays a login for, but if they are logged it says "welcome <user>". Thus far everything works perfectly. The place where i am having issues is when the user isn't logged in it shows the form, then they proceed to log in. Upon successful authentication i have the login script doing something like this

Unicode Issues...
I was wondering if anyone could give me some suggestions to an issue that I am having. Basically, I have a simple form posting the field results to a database, and a method of editing the data that is being entered. So, I have a user typing out unicode lets use the trademark symbol (&#8482 -> ™.

The data is Posted to the form processing page and is entered into the database as the actual unicode (as it is typed out). The issue is that when the code is in edit mode, it exists in the page source as unicode (as it was typed into the form), but displays to the user as the symbol, which is also correct. The problem is that when I hit submit and Post the data to the processing page, the symbol is being Posted not the actual code for the symbol, which was originally typed into the input box and which existed in the source code of the edit input box's value.

Is there anyway to escape this, and on what end (the edit form display or the edit form's processing page)? I already played with the utf8_encode/decode fucntions with no results. I would also consider htmlentites(), but haven't tried as of yet.

DOMXML Issues
I've been stabbing at this for the past hour and I figured it out, but
there's some erratic behavior under certain conditions that I think I
should mention...

I used tidy to clean up an html document before reading it into an xml
document via DOMDocument->loadXML(). When I load the page via
loadXML(), the XPath won't return values at all for queries other than
"//" "*" or "." (such as //a, etc)

When I switch to DOMDocument->loadHTML(), it works fine.

I was wondering if anyone could give me a reason for this. It works
now, so I'm not complaining, just there was nothing in TFM to lead me
to believe this behavior would arise.

PHP And SELECT Box Issues
I have an input form for which I've created a "matrix" for user input.
Basically, the user chooses a radio button and then through javascript, a
select box is displayed to define a value for that radio option, like so:

Choice: (Radio1) type: (select box1)
Choice: (Radio1) type: (select box2)
Choice: (Radio1) type: (select box3)
Choice: (Radio1) type: (select box4)
Choice: (Radio1) type: (select box5)

I know, it looks confusing and is ;)

Now the problem is weird:

After a record is stored, I want to also pull out the data and repopulate
this form with it. I've used the "checked" attribute to define the correct
radio button, and the "selected" attribute to define the selected dropdown
value. This works properly and appears in my HTML properly however when I
make a new choice in the drop-down select box, the value designated as
"selected" always takes precedence when the form is posted.

I really need the user to be able to modify the selct box for the radio
button that has been checked, or to pick a new radio button and then choose
options from that associated select box. For the sake of orderly
presentation, this is the easiest method I have found but for PHP, I need
to override the "selected" value if something new has been chosen.

To clarify a bit further, here's an example of the HTML to visualize
things:

<html>
<head>
<title>Select Box problem example.</title><meta http-equiv="Content-Type"
content="text/html; charset=iso-8859-1">
<script language="JavaScript" type="text/javascript">
<!--
function hide(id){
if (document.getElementById && document.createTextNode){
spans=document.getElementById
('mainform').getElementsByTagName('span');
m=document.getElementById('mainform');
for (i=0;i<spans.length;i++){
m.getElementsByTagName('span')
[i].style.visibility='hidden'
m.getElementsByTagName('p')
[i].style.background='#eee'
m.getElementsByTagName('p')
[i].style.borderColor='#ccc'
}
if(id!='none'){
m.getElementsByTagName('span')
[id].style.visibility='visible'
m.getElementsByTagName('p')
[id].style.background='#ffc'
m.getElementsByTagName('p')[id].style.borderColor='#
000'

problem i'm having is that my memory usage just after creating less
than 5 graphs is already at 3.5 megs, and i need to create over 100

suggestions on how alleviate this problem?

Session Issues
I'm building a simple login form with a "remember me" checkbox. I've done
this before, just keeping the username and a hash of the password in a
cookie, and changing the expiration of the cookie based on the checkbox, but
this time I want to use sessions instead.

There's another site I was looking at which gives you a session cookie
immediately. When you log in, log out, quit the browser, or anything, the
cookie still contains the same session id, whether or not you checked the
remember me box. So the session hasn't expired, yet they still have the
"remember me" functionality.

How do you do that?

I'm thinking of tricks surrounding saving the time they logged in and
whether they chose the checkbox, but all of them would log a user out
eventually if they sat on the same page for too long.

Compiling Issues
I'm having issues compiling php v4.2.2 on Redhat 9.0. The goal
ultimately is to compile in mcrypt support, but that's a bit down the
road from here. I've chased down the dependencies for the configure
options below (I think), but it still won't configure.

It appears to be choking on MySql (v3.23.54). The error I get is
something like:

/usr/bin/ld : cannot find -lmysqlclient

However, /etc/ls.so.conf appears to point to the correct directory:
/usr/bin/mysql, the contents of which are listed below.

PHP Cookies Issues
I am calling an application which needs some cookies to be set to function properly. The appln sets some cookie parameters on login and on furthur calls it require these cookies to follow.

I was successful in storing the cookies as a txt file using CURL. But in the furthur calls , how to pass that?

from curl tutorial i came to know that the cookies are automatically passed to the furthur calls. But how can i check that? If i have one variable Jsessionid in the cookies test, how can i check whether that variable remains the same in the next call?

Also, setting the cookies in the header and calling an url like http://xyz.com?JsessionId=abcd are same or not?

PHP $_GET Issues
I'm not sure if this is out of scope for this forum, because it also entails a little bit of SQL. If this is out of scope, please let me know. Here is a bit of my code:

$isbn = $_GET['isbn'];
if ($_POST['_submit_check']) {
if ($_POST['yes_no'] == 'yes') {
$delete_sql = "DELETE FROM lounge WHERE isbn = $isbn";
$db->query($delete_sql);
print "Entry deleted";
} elseif ($_POST['yes_no'] == 'no') {
print 'Entry not deleted'
}
} else {
print "Cannot process form";
}

I am trying to delete a record from a MySQL database. I am getting some information from the url: www.domain.com/delete.php?isbn=123 and use that isbn=123 as part of the SQL statement. I can print the $_GET['isbn'] on the screen and it works. The SQL query works in phpmyadmin when I use isbn = 123, but it won't work when I assign the $_GET['isbn'] to a variable named $isbn. I think I am having some problems putting these two things together. I can post more code if needed.

Unicode Issues
I'm playing around with an OpenID implementation, which uses cURL to send/retrieve the relevant data. The actual OpenID bit is working nicely, I can authenticate just fine. The problem, however, is when I use the Simple Registration Extension to retrieve a nickname from the ID server.

The nickname (and everything else, really) is supposed to be sent accross in UTF-8 format. For some reason, however, it seems like curl_init() is converting to a different character set, causing validation to fail for nickname's with non-Latin characters (like the ÃƒÂ» in my nickname). I've tried just about everything, including curl_init( utf8_encode( $url ) ); but nothing seems to work.

Login Issues
I'm working on getting a new user registered into both phpbb and into an opensource game called phpdiplomacy (can be found on sourceforge). I've gotten far enough where I can get the user registered/inserted into both databases. But when I attempt to login in to the game, I'm told I have a bad password. Although the encrypted pass in both the phpbb table and games table is the same. I'm not sure, but the game's config file contains the following, which may be affecting the game login:

var $random='enter30charactarshereplease'
/*
This is used to salt hashes, and the md5 hash of this is appended to the directory
that errors are logged to. *This should be long ( ~30 charecters), random, contain lots of weird charecters, etc* If this isn't changed or is predictable it is a serious security risk.

Issues With SWITCH
Alright. I have a form on let's say, page 1 and the form contains a dropdown with numbers as values.

IE:
<select size="1" name="store">
<option value="1">Auburn</option>
<option value="2">Camillus</option>
<option value="3">Canandaigua</option>
<option value="4">Colonie</option>
<option value="5">Cortland</option>
<option value="6">Great Northern</option>
<option value="7">Liverpool</option>
<option value="8">New Hartford</option>
<option value="10">Oneonta</option>
<option value="12">Shoppingtown</option>
<option value="13">Vestal</option>
<option value="14">Watertown</option>
</select>

Now, the form get's directed to page 2 and I have this code:

switch ($_POST[store]) {
case 1:
$stadr = "1234 duffy ave";
$cszip = "New York, NY";
$phnum = "111-222-3333";
case 2:
$stadr = "1234 duffy ave";
$cszip = "New York, NY";
$phnum = "111-222-3333";
case 3:
$stadr = "1234 duffy ave";
$cszip = "New York, NY";
$phnum = "111-222-3333";
case 5:
$stadr = "1234 duffy ave";
$cszip = "New York, NY";
$phnum = "111-222-3333";
case 6:
$stadr = "1234 duffy ave";
$cszip = "New York, NY";
$phnum = "111-222-3333";
case 7:
$stadr = "1234 duffy ave";
$cszip = "New York, NY";
$phnum = "111-222-3333";
case 8:
$stadr = "1234 duffy ave";
$cszip = "New York, NY";
$phnum = "111-222-3333";
case 10:
$stadr = "1234 duffy ave";
$cszip = "New York, NY";
$phnum = "111-222-3333";
case 12:
$stadr = "1234 duffy ave";
$cszip = "New York, NY";
$phnum = "111-222-3333";
case 13:
$stadr = "1234 duffy ave";
$cszip = "New York, NY";
$phnum = "111-222-3333";
case 14:
$stadr = "1234 duffy ave";
$cszip = "New York, NY";
$phnum = "111-222-3333";
}
PLEASE NOTE that each case has a different address I just changed it for the sake of posting it here. Now, when I run through page 1 and hit submit it always displays case 14's variables. So, I went and I put an echo statement at the top (ie: echo $_POST[store]; ) and it returns the proper values. I just cannot figure out why It' not working. Please, any advice would be very much appreciated!

Obviously im missing something fundamental here. Can anyone point me in the right direction?

Inlcude() Issues
I am trying to do

include("theme/menu.php?index");

what this would do it run the menu.php page and because ?index is there the menu.php page would recognize that the $_GET['index'] is set and then generate the code for the index menu. This also works with $_GET['section'] and $_GET['project']. Since there is going to be 3 different menus, but the top and bottom of all those menus are the same and it saves on number of PHP pages.

I saw fit to just make one menu file. Except well as we all know or, like me, seem to find out; PHP will not let you run a $_GET when including a file. Is there a way to by pass this or another way I can pass the information to the menu.php page. For testing I'm using a $_SESSION['MENU'] = 'index'; variable but I hate to have to keep doing that. Or is that my only hope to get this to work?

Register_shutdown_function Issues
I was astounished by the idea behind register_shutdown_function(), since it was the perfect solution for my problems with a web system developed in PHP.

The problem, as I've soon discovered, is that the function registered by this command is always called, meaning that even if a PHP script ends normally the shutdown function is called, messing everything up - since my registered function is intended to unregister sessions and so on IF a script dies abnormally.

Is there a workaround on this? I mean, I'd love that the function is still called if the user closes the browser or hits the stop button. The problem is I don't want it to be called if a script ends normally. Maybe I can do something with exit(int status) ?

Even if I can do something with exit(), what about if a script redirects to other, via the header() function?

Some Header() Issues
I am having a bit of problems with the header() function. I am trying to do a simple script that redirects to a certain case id. Javascript (location.href) is not possible (at least not with my knowledge of javascript) since it has to work on Windows 2003 Server, and it ignores/blocks/prevents this javascript. So, I turned to header() and with the respective ob_start() and ob_end_flush() it works well in standard. Works:

header("Location: list.php");

Does not work:
header("Location: list.php?id=$id");
(simply assume $id is a number)

Is there anything I have missed regarding header? Can i get this to work or can it be done in another way?

Performance Issues
I am running a fairly large php/mysql app. In total it is only about
100 or so separate php files, but it is large because I have multiple
clients and each currently gets their own directory with a copy of each
of these files, which adds up quickly. Code:

Issues With A Check Box
I set up a field in a table in a database as follows:

enum('Yes', 'No') with a default of Yes

On a php page I have the following form:

<input type="checkbox" name="contact" CHECKED/>

and then I have this to check the form input and to create the quiery

$contact = isset($_REQUEST['contact']);

$query = "INSERT INTO contest (contact) VALUES ('$contact')";

My problem is that when the user keeps the box checked a record of YES stays in the database but when they uncheck it, nothing appears in the DB...where I would like it to say "No" instead of being null...

Any way to fix this? Is it a DB thing or a script thing?
