$this only makes sense in methods, not in functions

this is ok

class Foo {
     function bar() {
          $this->...

this is not

function some() {
    $this->

// edit: didn't notice he passes "$this" as parameter

advice: simply replace "$this" with "$somethingElse"

You will also get this error if you use self::bar() even inside Foo. – gcb Jan 19 '11 at 22:41
You will also get this error if you declare you method as static. All static methods are considered to be called outside the class scope – gcb Jan 19 '11 at 22:42

You cannot pass $this to a procedural function. $this is a reserved variable.

As per my comments. You want to use $this as passed variable and php doesn't allow it outside class methods body.

function DoEvents($obj) {

    global $_CONF, $_PAGE, $_TSM , $base;

    $jpp = $obj->vars->data["jpp"];

    $cache["departments"] = $obj->db->QFetchRowArray("SELECT * FROM {$obj->tables[job_departments]}");
    $cache["locations"] = $obj->db->QFetchRowArray("SELECT * FROM {$obj->tables[job_location]}");
    $cache["names"] = $obj->db->QFetchRowArray("SELECT * FROM {$obj->tables[job_names]}");
    $cache["categories"] = $obj->db->QFetchRowArray("SELECT * FROM {$obj->tables[job_categories]}");

yes ! thats the issue! how silly im! sorted just before your comment... you life saver too!! thanks a lot!!! super you guys are! — designer-trying-coding, Oct 29 '09 at 14:42

You have to make the object first.

   $object=new Myobject;
   DoEvents($object);
