using define will make a constant which is available anywhere - so you don't need the $smarty->

once you have defined it you can access it anywhere. (good practice to use uppercase for constants - helps you identify them in your code)

Can you give an example please?

Do you mean do this
[code]
$smarty = new Smarty();
DEFINE('SMARTY', $smarty);
[/code]
Then inside a class function i do[code]SMARTY->blah();[/code]
Elaborate a little more please.

Ok what i want to do is define one variable and use it throughout the whole class and it's functions.
Say it's smarty. How can i do[code]$smarty = new Smarty();[/code] once and use it regulary throughout my functions in the class without having to define it every time in every function?

Example:

Somehow i define smarty and then

[code]class MyClass{
    function MyFunction(){
          $smarty->define('var', $var);
    }
}[/code]

I used IPB many times before and never had any hacking problems. I think it's great software.

[Need help with this.]

What am i missing?

My MySQL class code:

[code]function assoc_array($sql){
$this->do_connect();
$sql_result = mysql_query($sql) or die(mysql_error());
if (!$sql_result)
        {
            $sql_error = mysql_error();
            echo "<br>";
            echo "<p>".$this->mysql['gen_error']."</p>"; 
            return(false);
        }
        else
        {
            $info = mysql_fetch_assoc($sql_result);
            return ($info);
        }
[/code]

And in my actual class the code is:

[code]function members_main(){
$smarty = new Smarty();
$mysql = new mysql();
$sql = "SELECT * FROM `user` WHERE username = '".$_SESSION['user']."' LIMIT 1";
$info = $mysql->assoc_array($sql);
$smarty->assign('full_name', $info['name']);
$smarty->assign('username', $info['username']);
$smarty->assign('email', $info['email']);
}
[/code]

it basicly shows up blank in smarty, means it doesnt work. Whats wrong?

The session does work i checked.

[Once again, need help.]

Ok i am trying assign a var to smarty though my class.

Here is the code:
[code]function members_main(){
$smarty = new Smarty();
$sql = "SELECT * FROM `user` WHERE username = '".$_SESSION['user']."' LIMIT 1";
$mysql = new mysql();
$info = $mysql->assoc_array($sql);
$smarty->assign('name', $_SESSION['user']);
}

function member_page(){
$smarty = new Smarty();
switch($_GET['do']){
default:
$this->members_main();
$smarty->display('main.members.tpl');
break;[/code]

Where you see [code]$this->members_main();[/code] if i replace that with [code]$smarty->assign('name', $_SESSION['user']);[/code] It works fine. But if i do it through [code]$this->members_main();[/code] it doesn't work. What am i doing wrong?

[SOLVED: Need help!]

Sorry i didn't mention that before i started my class i have

[code]include("config.php");

//Global mysql variable.
global $mysql;[/code]

[SOLVED: Need help!]

Sorry if it's noobish but i am just learning classes and i just can't get this fixed.

Basicly i wrote a mysql class and now have hell of errors saying it does not let me connect to the database, is it me or am i doing something wrong. I use WAMP so i use root for username... no password, localhost and db name is correct as well.

Here is the MySQL class.(part of it)

[code]class mysql {

//MySQL var

var $mysql = array();

//MySQL settings.

function settings(){
//MySQL settings.
$this->mysql['host'] = $mysql['host'];
$this->mysql['user'] = $mysql['user'];
$this->mysql['pass'] = $mysql['pass'];
$this->mysql['dbname'] = $mysql['dbname'];
//MySQL errors.
$this -> mysql['con_error'] = "<b>MySQL encountered a severe error while trying to connect to the host</b>n";
        $this -> mysql['db_error'] = "<b>MySQL encountered a severe error while trying to use the database</b>n";
        $this -> mysql['gen_error'] = "<b>MySQL Error: <b>Due to a database error this page cannot be displayed</b>n";
}

//MySQL connect function.

function do_connect(){

$this->settings();

$connect = mysql_connect($this->mysql['host'], $this->mysql['user'], $this->mysql['pass']);
$db = mysql_select_db($this->mysql['dbname']);

if(!$connect){
echo "<br>";
echo $this->mysql['con_error'];
}elseif(!$db){
echo "<br>";
echo $this->mysql['db_error'];
}
}

//MySQL query function

function sql_run($sql){
$this->do_connect();
$res = mysql_query($sql);
if(!$res){
echo "<br>";
echo $this->mysql['db_error'];
}else{
return($res);
}
}

//MySQL mysq_num_rows function.

function num_rows($sql){
$this->do_connect();
$now = $this->sql_run($sql);
$res = mysql_num_rows($now);
if(!$res){
echo "<br>";
echo $this->mysql['db_error'];
}else{
return $res;
}
}[/code]

Please help, what am i doing wrong?

[Help a guy with classes :D]

Okay someone helped me at the other forum, thank you tho.

[adding variables into url like 'index.php?action=1']

If you are using html then it should be

[code]<a href="?action=1">Click here</a>[/code]

Try that, works for me.

[Help a guy with classes :D]

I want it to echo the contacts in rows. Okay i'll ask in the smarty forum after i figure out what to put in the class first.

[Help a guy with classes :D]

I am coding a simple guest book and i haven't made classes related to Smarty yet so i need help.

My code is as follows:

[code]function show_contacts($user_id){
$this->mysql = new mysql();
$sql = "SELECT * FROM `contacts` WHERE 'owner' = '".$user_id.'"'";
$this->contacts = $mysql->assoc_aray($sql);
while($this->contacts){
//what here ?
}
}[/code]

That is the code inside a class, i also made a mysql class before that but what do i have to put where it says "what here?" and what do i put in a .tpl file in smarty in order for it to list the contacts? :)

Thank you.
