Using php 5.2.13
PHP Fatal error: Using $this when not in object context in
/home/xxx/public_html/xxxactex/x/lib/User.class.php on line 227
I have a hard time understanding "object context" right now 
It's easier for me to understand HTML...
I intentionaly broke the lines arround line 227.
There goes the code :
PHP Code:
function listUsers($start=0, $count, $order ='user_lastname', $dir='ASC'){
$sql = new MySQL_class();
$sql->Create();
$users = array();
$qry = ' SELECT u.user_id, u.user_firstname, '
. ' u.user_lastname, u.user_email, u.user_status,'
. ' u.user_created '
. ' FROM tblUsers u '
. ' ORDER BY ' . $order . ' ' . $dir
. ' LIMIT ' . $start . ',' . $count ;
$sql->Query($qry);
if($sql->err_no != 0){
*****line 227[COLOR=black]*** [/COLOR] [COLOR=black]$this->err_no = $sql->err_no;[/COLOR]
$this->err_msg = $sql->err_msg;
}
for($i=0; $i<$sql->rows; $i++){
$sql->Fetch($i);
$user = new User();
$user->user_id = $sql->data['user_id'];
$user->user_lastname = $sql->data['user_lastname'];
$user->user_firstname = $sql->data['user_firstname'];
$user->user_email = $sql->data['user_email'];
$user->user_created = $sql->data['user_created'];
$user->user_status = $sql->data['user_status'];
$users[$i] = $user;
}
return($users);
}
Thanx for your help.

User pastebin or some similar site to paste all the User.class.php
It's ok for now to replace this:
$this->err_msg = $sql->err_msg;
with this:
$err_msg = $sql->err_msg;
This way your site will work, but errors will not be shown.

Thanx for the replies.
Here's the complet user.class.php code...
here's also what sean1984 gave in reply.
PHP Code:
class User_Class_Name extends .... {
public $[COLOR=black]err_no[/COLOR] = 0;
public $err_msg = NULL;
function listUsers($start=0, $count, $order ='user_lastname', $dir='ASC'){
.....
if($sql->err_no != 0){
[COLOR=black]$this->err_no = $sql->err_no;[/COLOR]
$this->err_msg = $sql->err_msg;
}
....
}
}
May you tell me where the above parts go ?
I feel terrible for asking so much, and thanx again :(

How do you call this listUsers function?
If you are calling it as static then you will see the error you have.
PS. If you are coding on php 5.2.13 you have to pay attention to the class rules.
You have to specify public, private or protected methods for your variables and functions.
And you have errors in your function declarations. (ex):
Code:
function listUsers($start=0, $count, $order ='user_lastname', $dir='ASC'){
The variable in red should be defined too if previous variable predefined. |
