[PHP] MySQL Login Setup not working with PHP

[Tim Burgan]

I've installed a bundle from ( www.fireworks.com.au ) that includes PHP,
MySQL and Apache all pre-configured.

All is working OK, except that I'm trying to access a table in my database
using the following PHP code:



The problem is that I don't know what my USERNAME or PASSWORD for MyDQL are.
How do I find this information out?

I thought it was in the 'my.ini' file, but with this installation there
doesn't seem to be one.

Alternatively, does anyone know of a very simple tutorial that explains
STEP-BY-STEP of how to install Apache, PHP and MySQL to run on a local
machine.. that even I can understand.

Thanks

[PHP] secure code

[Tim Burgan]

Hello,

I'm wondering if you can recommend any resources that discuss writing secure
code and how to put the best methods in place to prevent hackers.

I'm particularly looking at resources from the web coding perspective, not
securing a server.

Or, what things to you do to 'block' hackers.

Thanks

[PHP] Planning a new job

[Tim Burgan]

Hello,

I'm wondering what processes everyone has before quoting a web programming /
design job?

Do you have a face-to-face meeting with the client?

What questions do you ask?

What information should be found-out about the job?

Do I then go away and draw up a quote? or a quote and a proposal?

Any help would be wonderful, thanks.

[PHP] PHP forms that are valid XHTML

[Tim Burgan]

Hello,

I'm *very* new to PHP. I am working through the 'Professional PHP
Programming' book by Worx.

In their forms they use the name attribute (ie. name="example") instead of
XHTML's id attribute (ie. id="example").

If I use 'name' my results display on the next page after the submit
button is pressed, but if I change it 'id' the results do not display.

How can I fix this?

Thanks

Re: [PHP] PHP forms that are valid XHTML

[Tim Burgan]

Thanks for your replies.

The name attribute is depreciated in XHTML for use with the input tag and
has been replaced with the id attribute.

The name element can still be used in the form tag though.

What I'm looking for is something similar to ASP's
GetElementByID("example");

Thanks

[PHP] function to remove all \" from a variable

[Tim Burgan]

Hello,
I'm using FCKeditor to edit content on my site.
But the content it produces escapes all the  " (double quote) characters 
from my HTML, and replaces it with \" (backslash-double quote).

Is the a function that I can use to change it back?
Does str_replace() do it.. if so is this how I use it:
str_replace('\"', '"', $_POST['FCKeditor1']);

On my page, all my content is updated via a textarea online.
If I include PHP code embeded with my HTML in the textarea, the database 
converts it to plain text, instead of code that can be used. It doesn't 
convert < to < though, it's still in the database as <, just when 
it's read out again.. it don't work!

[PHP] Why does PHP have __toString() and not just toString()

[Tim Burgan]

Hello,
I'm a University student studying Java, but I also do some freelance web 
design - so naturally I do a fair bit of PHP which seems to be very 
similar to Java.

Usually I just code PHP as I need it, but down the track get REALLY 
annoyed when I need to edit or update my code. It's hard to follow and 
doesn't really have any order.

Then it came to me - why don't I code PHP with classes and plan my PHP 
like I do with Java. So today I looked into the PHP manual to find out 
about classes and objects in PHP.

I'm wondering, why does the toString() of classes have two underscored 
preceding it [e.g. __toString()], as opposed to Java's normal toString()?

What's the purpose of the two underscores in PHP's classes?
Thanks

[PHP] Fatal error: Call to a member function on a non-object

[Tim Burgan]

Hello,
I have a database driven (MS Access 2000) PHP website that runs fine on 
my localhost (Apache, WinXP, PHP 4.3.9), but when I upload it to the web 
host (IIS, PHP 4.3.10) and try to access a page I receive the following 
error:

Fatal error: Call to a member function on a non-object in 
c:\XXX\inc\dbConnOpen.php on line 17

The file in question contains code that forms a connection to the 
database. I've used this EXACT same code on this same website for the 
last 8 months (both on localhost and web host) with no problem.. then 
when I upload the WHOLE site again.. it doesn't work.

Here's the contents of the above file:
/* Open database connection */
  $db_connection = new COM("ADODB.Connection") or die("Cannot start ADO");
  $db_connstr= "DRIVER={Microsoft Access Driver (*.mdb)};DBQ=" .
realpath("directory/database.mdb") . ";DefaultDir=" .
realpath("directory");
  $db_connection->open($db_connstr);  // THIS IS LINE 17
Can anyone shed some light onto what this error means in plain english, 
and possible what I can do.

Thanks for your time.. I'm in a bit of a pickle.

[PHP] strange sessions

[Tim Burgan]

Hello,
I'm experiencing a weird thing regarding sessions - that I'm using for 
user authorisation.

I have a page that the "public" can view (index.php) that includes a 
login button. When the login button is clicked a new window pops-up and 
asks for username and password. The user is then logged-in. The parent 
page then detects using sessions that the user is logged-in and includes 
the text and link "Joe Bloggs: [logout]".

All the public content on this website is viewed via index.php. For 
example, a URL to "about us" or "contact details" may be 
index.php?keyword=about or index.php?keyword=contact.

The a user is not logged in, all links within the page work fine, but 
when the user IS logged in, a hyperlink from one page to another page 
(whose URL contains a different 'keyword') doesn't work. The browsers 
address bar updates to reflect the new page, but the web page never 
changes (even when I physically type a different 'keyword' into the 
address bar). Changing physical files (ie. index.php to main.php) does work.

As soon as I click 'logout' which destroys the user's session, 
everything returns to normal.

Is there something I'm missing here?
Thank you for your time.
Regards
Tim

Re: [PHP] strange sessions

[Tim Burgan]

Hello,
Here's a link to a website demonstrating my problems: 
<http://www.timburgan.com/problems/>
You can download the code from the site or here: 
<http://www.timburgan.com/problems/files/site.zip>

I'm experiencing some weird issues with sessions, and because I'm quite 
new to PHP and sessions.. I'm a bit lost. My use of headers also seems 
to be playing up.

I'd really appreciate it if someone has time to assist me, look at my 
code, and solve some of my problems that are described below.

On my website, there are 3 types of users:
  1. Students
  2. Staff
  3. Admin
There are many students, and students are able to login and edit their 
own page, but they have no rights to edit other student pages, staff 
pages, or any other pages.

There are many staff members, and staff are able to login and edit their 
own page, but they also have no rights to edit other student pages or 
staff pages. BUT THEY ARE ALLOWED TO EDIT ANY OTHER PAGES.

The admin is also staff member, but they are given admin status and 
therefore able to edit anything - including any students, staff, or content.

When someone logs-in successfully, they are taken to the editing page. 
If the editing page is then closed and the user tries to navigate the 
site as any normal "non-logged-in user" would (by clicking the 
navigation links), the address bar in the browser changes, but the 
content stays the same and doesn't change.

Also, when someone logs-in successfully, they are taken to the editing 
page. If the editing page is then closed they are returned to the 
original page they were trying to edit. If the user then clicks [edit 
this page] again, it says they do not have permission to edit this 
page.. even though they do!

By the way- to login, staff are Joe (username & password are both: joe) 
and Simon (username & password are both: simon). Students are Tim 
(username & password both: tim), and Grace (username & password both: 
grace).

Thank you very much for your time and assistance.
I cannot thank you enough.

[PHP] php style guides

[Tim Burgan]

Hi everyone,
What 'rules' do you follow about styling/formatting your PHP code? Do 
you follow a guide that is available online?

I generally have my own preference for formatting like
if ( condition )
{
   statements;
}
for all conditional statements and loops, as opposed to
if (condition) {
   statements;
}
But what I'm really wanting to get everyones thoughts about is in regard 
to combining PHP with HTML.

I used to do:
test
but just tried
test';
  echo 'blah';
?>
which I find it's much easier to read to code.
What do other people do and for what reason? What are the 
advantages/disadvantages to doing it certain ways?

Thanks for your time.

 echo '
 
 if ( $_SESSION['createStudent_expireYear'] == $today_year + $i )
 {
echo ' selected="selected"';
 }
 
 echo '>'. $today_year + $i .'';

 0"0
 1" selected="selected"1
 2"2
 3"3
 4"4

/* Query the database */
$db_sql = 'SELECT id, expiry, permissions FROM tblStudents UNION ALL

[PHP] Session errors when uploaded to host

Hello,
I've developed my site, and tested on a web host (Apache, PHP 4.3.9).
Now I've uploaded to a different host (IIS, PHP 4.3.1) where I want to 
keep it, and I get session error messages like:

Warning: session_start() [function.session-start 
]: 
open(/tmp\sess_30f6794de4b0d80b91035c6c01aae52d, O_RDWR) failed: No such

- headers already sent by (output started at 
E:\W3Sites\ywamsa\www\timburgan\index.php:9) in

My code on line 9 is: This is the first line of my code
session_start();
My code on line 12 is: This is the second line of my code
header("Cache-control: private");
Is there any solution to this?
Tim

PS. I looked up session_start() in the PHP manual, and found this 
comment that may offer a solution that I've pasted below. Will this 
work? Are my problems a bug with PHP and IIS?

[START QUOTE]
*tech at insights dot net dot au*
17-Oct-2004 04:28
|I am sure anybody that is trying to use IIS and PHP is throughly 
annoyed with the session_start() bug that recreates a new session every 
time it is accessed.

The problem is the session_id isn't passed before the session_start() so 
it creates a new session. So a simple sollution is:

$id = 473483478383834;
session_id($id);
session_start();
Another way that is a bit more dynamic using a Cookie to hold the 
session_id:

if (isset($SessID)){ session_id($SessID); }
session_start();
header("Cache-control: private"); // IE 6 Fix.
setcookie("SessID", session_id(), time() + 3600); 

There are probably much better ways of doing this but for use with my 
offline Win/IIS setup it seems to be fine.

[PHP] Writing a PHP Web application

[Tim Burgan]

Hello,


What are the options to get code to run on the server (every XX
minutes), without any user interaction, etc.
Example 1: If I have a directory that contains files, can I write a
script that will delete all files older that 5 days?
Example 2: If I write an email web application, and the user wants to
send an email to 50 people, can I write a script that will send emails
individually XX seconds apart from each other, but have the progress
interfaced with the web page the user is on so they can see the
percentage progress of sent emails.

Is this possible? How do I do such things?
Are there any resources available that can help me with this?

Also,  back to the email example, is it possible that once an email is
composed and sent, that the web application can scan the email for
viruses, then show a message to the user if a virus was found in their
email, if no virus found, the email is then sent to the users as above.

How would I scan an email for viruses (or spam?)? And, scan it only once
so that system resources are not used to scan unnecessarily for every
recipient?

Any help would be greatly appreciated.


Thanks
