 Call to a member function read() on a non-object..
Hi,
I am trying to make a xml-rpc client & server for the oscommerce script. but when i m trying to invoke it, it is giving me this error
Code:
PHP Fatal error: Call to a member function read() on a non-object in C:\\Program Files\\EasyPHP 2.0b1\\www\\oscommercev3\\includes\\classes\\database.php on line 487
Line 487 of database.php is this
PHP Code:
function execute() {
global $osC_Cache;
if (isset($this->cache_key)) {
if ($osC_Cache->read($this->cache_key, $this->cache_expire)) {
$this->cache_data = $osC_Cache->cached_data;
$this->cache_read = true;
}
}
There is a file application_top.php which instantiate $osC_Cache.
when i include application_top.php in normal php functions file, it works perfectly but when i use in xmlrpc server file then it gives me above error.
Can anybody suggest me a solution??

PHP is saying that there is NO function called "read" in the "$osC_Cache" object. So my guess is that your xml-rpc is not including the "$osC_Cache" object file the right way.
I recommend a var_dump or something to see if $osC_Cache is empty. If it is, you will know you need to check your require()/include() code. Also, If the file that makes the $osC_Cache obj is not being included - it won't even be an obj - just a null variable.

no I dont do PHP at all and im a .net guy but I thought that error means that the object hasnt been instantiated (sp?) yet.
You need to create a new instance of the object. now i have NO idea wha the hell global $x means. lol
how do i know this: i was debugging oscommerce for a friend yesterday. this guy has a done a lot for me ,and even i know i have no idea for php i decided to take a look at it. I think i broke it, but fixed it temp.
I was getting that same error (different file, line) though, and i looked at it and it said
if something = true {
$x = new y
}
$x -> blah.
and i just took the if statement out and it worked lol

Yes, that is what I said. If there is no function read() in that object AND YOU KNOW FOR A FACT THERE SHOULD BE - then that means the object was not created and so you didn't included the file that makes it.
in other words,
PHP Code:
$osC_Cache = null;
Also masfenix, "global" means bring a variable/obj/array from outside the function - inside so that function can work with it.

There is application_top.php file which is initializing osC_Cache
PHP Code:
require('include/classes/cache.php');
$osC_Cache = new osC_Cache();
the problem is when i include application_top.php in normal plain php file, it initialize osC_Cache & works perfectly but when i put same file in my xmlrpc server.php file it give me this error.

Well, you have to look back over your require('include/classes/cache.php'); code because some how that obj is NOT being created.
Is there anything that might over-write it?
Did you try a var_dump to see what that obj had in it by the time it makes it to your code?
Did you try making a "core.php" that every script calls that will handle all the included for your files? Like:
PHP Code:
<?php
require($db);
require($file1);
require($file2);
...
?>
So all files will have the same way of including?

My tip - When trying to debug something echo\print EVERY variable from inside the method to see if the values are what you expected. If they - Echo every variable from OUTSIDE the method to see if it's what you expected.

echo/printing is useless on Objects.
Use var_dump: php.net/var_dump
