Fatal Error after Installing!

August 9, 2005

Fatal error: Call to undefined function: link_session_variable() in A:\www\webshop\includes\functions\sessions.php on line 95

What is wrong ?

Im running a PHP4+ server with OSCMS2.2 and Register Globals "OFF" Contrib.

The Installation runs fine but when i view the page this is what?s shown.

Any ideas ?

Oh yea.. A: is not the Scratch drive :P

It looks as though the session has not started. Above that code there is already a reference to link_session_variable, so if it was not recognised then the error would have shown on line 77.

You lost me there :blush:

Ive pasted the code as it is after the Register_Globals_Off Contrib and as it was modded before installation.

Well ive patched that up and now i face yet another problem <_<

Parse error: parse error, unexpected '}' in a:\www\webshop\includes\functions\sessions.php on line 83

Fatal error: Call to undefined function: tep_session_name() in a:\www\webshop\includes\application_top.php on line 145

any ideas or should i just eraze all and start over ?

1. Deleting all old code.

2. Download another fresh OSCms2.2 install

3. Patch with a Register Globals OFF patch

or what do you guys think..

You have a simple typo in \includes\functions\sessions.php - I would just fix that.

Looks like you have an extra curl bracket on line 83 :-"

<{POST_SNAPBACK}>

So when i change all return $success; to $success

and all $nothing = 0 to $nothing

i get:

Parse error: parse error, unexpected '}' in a:\www\webshop\includes\functions\sessions.php on line 83

Fatal error: Call to undefined function: tep_session_name() in a:\www\webshop\includes\application_top.php on line 158

In line 83 i find a } and when i delete it i get this:

Parse error: parse error, unexpected T_FUNCTION in a:\www\webshop\includes\functions\sessions.php on line 85

Fatal error: Call to undefined function: tep_session_name() in a:\www\webshop\includes\application_top.php on line 158

Line 85 says: function tep_session_register($variable) {

and Line 158 says: $GLOBALS[$var_name] =& $nothing;

Just tell me it?s simpler to reinstall the whole shop and the n apply the Register globals patch ?

Thing is that i started like this....

My webhotel dosent support script?s wuth Register globals set to ON because of the unsecure injection possibillity...

so i installed the shop this way..

1. i downloaded the OSCms2.2 from you guys "A clean install"

2. i downloaded the contrib Register globlas OFF and patched the code..

3. i uploaded it all "Patched and ready to my webhotel"

4. i ran the installation... then i got the errors above...

The missspelling and extra lines and extra chars must come from the contrib..

because i shure didn?t edit any lines myselve :P

Which Register Globals Patch did you install? There is the original one, where you have to appy the edits yourself to the pages - and this is a long install and it's dead easy to make an error or two. This is why I put them all together into a set of Register Globals Patch Files - specificlly for new installs. All you have to do is to overwrite the default files with the patched files and you're good to go.

The link to the ready-made patched files is below my name.

If you already used that contribution of mine then there's a problem somewhere else that's affecting it (providing you installed all of the files from my contribution) - because no one else has a problem after installing this contribution.

I think it was the long install where you had to edit meny specific files...

so ill just end this with a "Ill delete all files and install a fresh ms2.2 with your patch instead :P

hope that saves me bounch of time :D

ill try to post a result afterwards :thumbsup:
