Re: [PHP] Jpgraph troubles

> I can see what headers are sent.  What is the url of the image?

I checked using curl -I and found that the correct headers are being sent. I 
found out it was because I didn't have a certain library I needed included 
within the graph script.

Thanks for your help anyway,
Cheers,
Jord

Jpgraph does that for you I think. As I said before, the script works when you 
access it directly, but not when it's through an img tag.

[PHP] Jpgraph troubles

[Jordan Elver]

Hi,
I've been creating some graphs using jpgraph and they work really well when I 
view them directly i.e. directly through the script. My problem comes as soon 
as I try to display them using the  tag within another page. When I do:



I can't get it to display. It just shows the broken image icon.

Any ideas whaty may be causing that?

TIA,
Jord

[PHP] Repeating Templates

[Jordan Elver]

Hi,
I checked the archives for this but couldn't find a simple answer.
I'm working on my own templating class. Mainly as a learning experience, but 
also because I only want something really simple.

I sort of know how to do simple variable substitution. I have something along 
the lines of this below. 

$name = 'Bob';

$page = new Template;
$page->assign('NAME', $name);
$page->display();

Which assigns the variable to a template variable like {NAME}.
So, that's fine. What I don't know how to do is repeat bits of templates. Say, 
from a db query or something. How can I repeat the rows for all the data?
Any tutorials or advice would be appreciated. Hope my question is clear :)

TIA,
Jordan

[PHP] More OOP

[Jordan Elver]

Hi guys,
After your previous advice. I have been looking at some more OOP for my 
application. Is this the sort of way a proper OOP application should be 
constructed?

I want to use smarty as my template language as well, how could I integrate 
that?

";

// get connections details
list($host, $username, $password, $type) = $details;

// connect to the database
if($connection = mysql_connect($host, $username, $password)) {

$this->raise_error();
}
}
}

class Login extends Database {

function Login() {

echo "Hello, I'm the Login class";

// connect to the database
$this->connect();
}
}

$c = new Database;
$c->connect();

Any pointers would be great :)

Cheers,
Jord

I was hoping someone would say that :)
How could I code that though. I've only just started with OOP and don't 
understand how I can inherit methods to classes? Is it a good idea to create 
a new object within each class which, for example, needs to do database stuff 
or should I inherit the methods?

I haven't found any clear examples of this kind of OOP, only the real basics 
(which I still need help with by the way :) ).

Thanks for your help,

[PHP] OOP

[Jordan Elver]

Hi,
I've been doing a little OOP lately and have a few questions.
I want to build an application, there a re lots of elements to the 
application: Authentication, Database, Presentation, Error Handling etc.

Now, I want to code this cleanly and make it reusable. So, a class for each of 
these elements would be a good idea? Say I have an Authentication class. It 
has to run on it own. Should I build database, error methods into each of my 
classes? That seems to defeat the point in the first place?

At the moment I seem to struggling with how to do somthing right and well, 
rather than the actual code :)

Thanks for any advice you can give,
Jord

[PHP] Authentication programming

[Jordan Elver]

Hi,
I'm about to start a new project which will require a login system. The system 
should allow for different types of access on a per page basis. I'm going to 
achieve the login system using sessions, which I have done before.

My problem is that I don't want to have to do much login checking on the 
actual pages within the system. I would like it to be included and handled 
oustide of the main application.



So, you set the permission for the individual page. I would also like to do 
this as a class, which I am not experienced in. I haven't found any very 
elegent solutions to this. Could anyone point out some urls or anything to 
show me in the right direction?

Cheers,
Jord

[PHP] Checking Checkboxes using Arrays

[Jordan Elver]

Hi,
This is doing my head in.
I'm printing out a lot of countires from a db and i want to select the 
countries (check their checkboxes) if they are equal to a particular country 
variable I have set or if they appear in an array. My code is:

$european_union = array('24', '17', '1', '58', '74', '80', 
'73', '83', '101', '103', '119', '144', '164', '186', '193', '212');
print_r($european_union);

if(mysql_num_rows($europe_result) > 0) {

while(list($id, $country) = 
mysql_fetch_array($europe_result)) {


if(($id == $register_country_of_origin) || 
(in_array($id, $european_union))) {

echo"\t $country\n";

} else {

echo"\t $country\n";

}
}

Can anyone give me some tips because if i select a country which is not in 
the array, it still checks all the boxes of the countires in the array?!

I hope this is making sense, I thikn this is what I want ;-)

Thanks,

Jord

[PHP] Session and header()

[Jordan Elver]

Hi,
I've got a login script that uses sessions. To end a login session, I simply 
delete the session variables and do a session_destroy() which seems to logout 
everyone ok. The problem comes when I do a header() call afterwards to 
redirect after logging out.

It seems the header() call stops my logging out working correctly?! Does 
anyone have an idea of why header would interfere with seesion functions?

Thank,

How can I access each of these variables, check if they are empty, then add

[PHP] Printing out usernames and logins

[Jordan Elver]

Hi,
I'm trying to print out a list of usernames and the times they logged in. 

I want to print it out like:

joe
fred
frank

Then when you click on one of the names it show just there login times, like 
this, so if I click on fred it prints out:

joe
fred
- 
- 
- 
frank

But it doesn't continue printing out the rest of the usernames after it's 
finished printing freds logins.

Any ideas would be appreciated.

The code seems to have something to do with the second query, I think :-( 

The code I'm using is below.

Thanks,

Jord

db_connect();
$sql = "SELECT id, username FROM users";
$result = @mysql_query($sql);

if(@mysql_num_rows($result) > 0) {

echo'This is a list of Members who have Logged In to their account with 
times and dates:';

while(list($id, $username) = mysql_fetch_array($result)) {

echo"$username\n";

if($username == $user) {

$sql = "SELECT UNIX_TIMESTAMP(time) AS time FROM user_logins 
WHERE user_id = $id ORDER BY time DESC";
$result = @mysql_query($sql);

while(list($time) = mysql_fetch_array($result)) {
echo date('h:i a l d F', $time)."\n";
}
}
}

} else {
echo error('No one has Logged In yet!');
}

[Jordan Elver]

Hi Richard,
Thanks for the advise. I was just wondering what other people do.
I don't think I'll worry about it too much ;-)

[PHP] Retrieving and Printing Categories

[Jordan Elver]

Hi,
I've got a load of records that are in different categories.
What is the best way to get all the records or selected records and print 
them in such a way that they are grouped (on the page) in their relevent 
category, like:

Fruit
-> Apples
-> Pears
-> Bananas

Vegetables
-> Carrots
-> Cabbages

etc, etc.

Sometime my categories are ina dfferent table, don't know if this matters?
How can I do this?

TIA,

Jord

Re: [PHP] DOCUMENT_ROOT

[Jordan Elver]

Thanks for the reply,
I'm not using virtual hosts on my local machine but I am on the production 
machine. What should DOCUMENT_ROOT return? I though it returns the directory 
of the current script. So if I had a site in 
/usr/local/apache/htdocs/cha/script.php then I would expect DOCUMENT_ROOT to 
return /usr/local/apache/htdocs/cha/, is that right?

Is it posible to setup a virtual host on localhost?

Cheers,

Jord

[PHP] Site Structure

[Jordan Elver]

Hi,
I have a site structure like:

-> root
---> includes
---> admin
---> images

I'm using headers and footers and they are in the includes directory. My 
pages in the root directory include the files like:

include('includes/header.inc');

Thats woprks fine, but i want to be able ti use the same headers and footers 
in the admin directory but, of course, the paths are going to be wrong.

How can i get around this?

Any ideas,

Jord

[PHP] Updating Sessions

[Jordan Elver]

Hi,
I've got a multi page form and I'm using sessions to keep track of all the 
variables between the pages.  SO I fill in page one of the form and add the 
variables to a session. Then I can go on completeing the rest etc. 

My problem is that I want my users to be able to go back to the pages they 
have already visited and edit the data (in the form) and then undate the 
variables in the session. But I can't update the session, so I thought if I 
called session_unregister and then session_register again then that would 
work, but it doesn't? 

How can I get around this?

Thanks for any help,

Jord

[PHP] Selecting Dates

[Jordan Elver]

Hi,
I'm trying to select records based on dates.
I have a table with dates in the format 2001-04-08 and I'm using the query:

SELECT name, description, date_time FROM events WHERE YEAR(date_time) = 2001 
AND MONTH(date_time) = 04 AND DAYOFMONTH(date_time) = 08

But it doesn't yield any records? I don't really understand why? It seems to 
be the last bit 'DAYOFMONTH(date_time) = 08' which cause a problem because if 
I leave it out of the query, it selects all records for a particular month in 
a particular year as expected.

Cheers,

Jord

[PHP] Best way to check if a query succeeded

[Jordan Elver]

Hi,
i was just wondering what you guys do to check if a wquery suceeded or not?
I know about mysql_num_rows() and mysql_affected_rows(), just wondered what 
you guys do?

I normally do something like:

$sql = "SELECT something FROM table";
$result = mysql_query($sql);
if(@mysql_num_rows($result) > 0) {
echo'Query Suceeded';
} else {
echo'Query failed';
}

[PHP] Login System with access levels

[Jordan Elver]

Hi,
I've got a db with a username and password in it. I can let people log in, 
like SELECT * FROM table WHERE username = username AND password = password.

But how can I add an access level column so that I can have different levels 
of security. So admin's can read everything, but users can only read certain  
sections. 

How could I add to my db and structure a query? 

Any ideas would be good,

[PHP] DB Abstraction

[Jordan Elver]

Hi,
I thought it was about time I started using a db abstraction class. Problem 
is, there are so many out there that I don't which one to start using?

I've heard of ADODB (I think).

Anyone have any suggestions?

Cheers,

Jord
