Newbie Question!

When I go to mysite.host.com/catalog, the following error comes up:

Fatal error: Call to undefined function: tep_session_name() in /home/vhosts/mysite.host.com/catalog/includes/application_top.php on line 137

Lines 136-140 of application_top.php have been pasted below. Please help me resolve this error. Thanks in advance.

// set the session name and save path
tep_session_name('osCsid');
tep_session_save_path(SESSION_WRITE_DIRECTORY);

// set the session cookie parameters

Best Regards

Pete

P.S. In your replies, please keep in mind i'm a newbie, thanks again.

justpete · January 18, 2005

I have been told that this refers to the function in catalog/includes/functions/sessions.php

function tep_session_name($name = '') {
? if (!empty($name)) {
? ? return session_name($name);
? } else {
? ? return session_name();
? }
}

Apparently, it is supposed to indicate that the fundtion code is missing.

If so, what should I do about it?

You should check your functions directory for the file :D

You have probably had a bad upload - the file either does not exist or is zero bytes in size.

Which file should i search for. What should i do if i find it?

justpete · January 18, 2005

Nope, nothing out of the ordinary in the functions directory.

avoisin · January 18, 2005

You could start by checking the DIR_WS_FUNCTIONS variable that resides in catalog/includes/configure.php, which points also to DIR_WS_INCLUDES. For my system, I have the following for those:

  define('DIR_WS_INCLUDES', 'includes/');
 define('DIR_WS_FUNCTIONS', DIR_WS_INCLUDES . 'functions/');

Perhaps one of these isn't going to the right place? That error suggests it can't find the sessions.php file at all, so it's probably looking in the wrong place.

justpete · January 18, 2005

Lines 26-29 show that the 'DIR_WS_FUNCTIONS' in catalog/includes/configure.php

Don't think there's an error there.

define('DIR_WS_INCLUDES', 'includes/');
 define('DIR_WS_BOXES', DIR_WS_INCLUDES . 'boxes/');
 define('DIR_WS_FUNCTIONS', DIR_WS_INCLUDES . 'functions/');
 define('DIR_WS_CLASSES', DIR_WS_INCLUDES . 'classes/');

So, what could it be. Just to note also, I implemented a register_globals contribution when i first downloaded OSCommerce. Any further help would be greatly appreciated.

<{POST_SNAPBACK}>

all I can deduce is that you tried to install register_globals modification and made some errors there. So I suggest to UN-install the modifications, restore the old files because it seems that your sessions.php file is no longer what it should be.

justpete · January 18, 2005

Thats what i'm trying to avoid because it takes ages. Thanks anyway. Can anyone find any other errors?

justpete · January 18, 2005

I just don't know what's wrong with line 137 in application_top.php!!!

January 18, 2005

There is nothing wrong with line 137 - it is calling a function from the sessions.php file which is not there (either the function is no longer there or the file is zero bytes in size) - replace the sessions.php file (backup your old if you have modified it), then see what happens :D

Matti

justpete · January 18, 2005

If i replace sessions.php with an old version, will i have to go through the installation process again? Will the configure.php files change? Moreover, is it possible to get rid of this function, if replacing the file still causes errors. If so how?

Thanks alot for all ur help

justpete · January 18, 2005

I replaced it session.php , and still the same error appears. How can i just get rid of this function.

justpete · January 18, 2005

I have pasted the sessions.php file below for your viewing. What are the errors and how should i correct them?

So, is that any help?

justpete · January 18, 2005

Someone must know how to easily resolve this issue...

Someone must know how to easily resolve this issue...

<{POST_SNAPBACK}>

Have you checked your application_top code above line 137?

justpete · January 18, 2005

I don't know what to check. Can someone please see if sessions.php is okay. Cheers.

justpete · January 18, 2005

Surely sombody must know!

justpete · January 18, 2005

Where are the PHP experts?!?

avoisin · January 18, 2005

You've got this in your code, which is different from your original code post:

// <<< END REGISTER_GLOBALS  function tep_session_name($name = '') {
  if (!empty($name)) {
    return session_name($name);
  } else {
    return session_name();
  }

which is wrong. You goofed when doing the install, and have commented out the function name! It should read:

// <<< END REGISTER_GLOBALS  
function tep_session_name($name = '') {
  if (!empty($name)) {
    return session_name($name);
  } else {
    return session_name();
  }
}

As to where the PHP experts are, they are right here - but you need to be patient with everyone, this is a free environment, and we certainly aren't getting paid to monitor the forums! Patience is a virtue ... :)

Hope this helps.

justpete · January 18, 2005

Thanks very much indeed. The error has gone. Just like to further stress how grateful I am to everyone for helping out.

Cheers.
