#1: class and global

Posted on 2005-03-19 02:07:05 by Mister Jack

Hi,

I'm trying to use a global object (declared at a upper level), but all I
got is :
Call to a member function on a non-object in
/home/pooly/public_html/templeet/modules/freedb.php on line 16

part of the code is :
$freedb =& new freedbaxs();
Function return_freedb_search($array)
{
global $freedb;
[snip]
$freedb->freedb_search($txt);

so, can I access an object allocated outside a function ? this
functionis meant to be a wrapper for that class, because I cannot access
directly.
thanks for you help,

I don't see an error in this code, perhaps you should give us a bit more
information.

Hmm, perhaps your problem is the failed connection to your database. Can
you verify this?

The initialisation seems to be ok, since :

Function return_freedb_search($array)
{
global $freedb;
$freedb =& new freedbaxs();
[snip]
$freedb->freedb_search($txt); //line 16...
}

works
and also


$freedb =& new freedbaxs();
$freedb->freedb_search("ploplop");
Function return_freedb_search($array)
{
global $freedb;
[snip]
//$freedb->freedb_search($txt); //line 16...

}

those line are all in a PHP file which is include if needed, by
parsing the template file.
So the file is include (then
$freedb =& new freedbaxs();
should be executed)

and return_freedb_search is call a bit later. Everythin has always
worked fine, but this is the first time I tried with an object, and
all i got is this error. that's really strange, and I really don't
have a clue about what is going on. (is the object disapearing ? )

there is no database connection involved here. if I displace the
$freedb =& new freedbaxs();
inside the function it's works.

I should give a try with a dummy object. (but the constructor, only
initialize empty array)

Ok, I've tried with a dummy class :

class dummy {
var $yank;
Function dummy()
{
$this->yank = "test dummy";
}
}

and the problem is exactly the same.
i've done
print_r($dummy);
is works ok outside the function, but inside print_r($dummy) doesn't
return anything, like $dummy wasn't existing, even tough I declared it
to be global... So the class n itself doesn't have anything to do with
it.
I'm really stuck with this. Is there any incompatibiliy with class and
global declaration ?
btw, I'm using PHP 4.3.10-8
thanks for your help,

Ok, i've found a workaround. So contrary to what is stated apparently
in the documentation I had to declara the variables explicitely
"global" to make it working and to create the object and assign
_without_ reference.

to sum up :

global $freedb;
$freedb = new freedbaxs();
function return_freedb_search($array)
{
global $freedb;
[snip]
$freedb->freedb_search($txt);
}

this is the one working.
