hey I'm having a problem with a bit of code, it's long so I shortened it to the problem area.

class my_class extends Connect {
 var $connection;

 function set_conn() {
  //this creates a connection and works as tested by another script
  $this->connection = new Connect();
 }
 function get_conn() {
  return $this->connection();
 }
 function get_data( $query ) {
  if(!isset($this->connection)) {
   print "Error connecting to the database";
  } else {
   $i = 0;
   $get = $this->connection->Query($query);
   while($data = $this->connection->FetchArray($get)) {
    $result[$i++] = $data; 
   }
  }
   return $result;
 }
}

Then I have on my main script the following :

$config = new my_class();
$config->set_conn();
$functions = new my_class2();
$functions->grab('','','');//this is all ok

then I have another class that extends that class

class my_class2 extends my_class {
  function grab($type, $limit='10', $cat='1') {
  switch($type) {
   case 'most_viewed_home':
    $q = "some query";
    my_class::get_data($q); //or $this->get_data(q);?
   break;
  }
}

the problem is, for some reason $connection is no longer set when I use the grab function. all I get is Error connecting to the database. I'm sure I'm missing something silly, however I can't work it out. Can anybody see the problem?

the problem is that the conection is initialized for config object ... but when you declare the new object functions you dont have a conection made for that object ... hope this makes some sense

basicly they are 2 separate objects .... it doenst matter if the are from inherited classes. $config has a conection opened ... $functions doesnt ...

you can either make a new conection for the functions object .... or add an if in the get_data functions that checks if there is a conection opened if not opens it
