8: Undefined index: id_member

[extremenewbie]

I have been getting this error consistently in my forum, does anyone know what causes this and how to fix it?

8: Undefined index: id_member

Using:
SMF 2.0 RC1
No mods installed

The error comes up using both themes I have installed. 3column Theme and Clean Theme... I dont think it has anything to do with the theme...

Thanks in advance....

Having same problem after changing my forum from 2.0 to 1.1.8

[Tyrsson]

Can you please post the entire error message.

[extremenewbie]

Sure thing, now I'm getting more.... (or possibly had them and didn't notice)

Run this and then clear the error log and post the new errors so we can figure out exactly where they are coming from.

To disable template eval via phpMyAdmin ( What is phpMyAdmin? )

Code Select Expand

REPLACE INTO smf_settings
   (variable, value)
VALUES ('disableTemplateEval', '1');

Just a little info for ya that I picked up along the way about undefined_index errors...

undefined_index usually means that a variable is being called and it is null or empty.  Best practice to get rid of these warnings in your error logs is to check if it is not empty or if it isset and then perform the necessary code.  For example:

Code Select Expand


if (!empty($Hello_Member_ndt)) {

// Continue on...

}

if (!empty($mark_read_button)) {


}

// OR YOU CAN TRY THIS


if (isset(Hello_Member_ndt)) {
// Continue on...
}

if (isset(mark_read_button)) {
// Continue on...

}

I think it's came from Ajax Chat.. like on mine

[Tyrsson]

That is a default language string. Its found in the index.template.php and is defined in the index.english.php.

[Kimmie]

k here you go

[greyknight17]

Kimmie, is this issue resolved now?

Is this error only showing up when members view a board? Clear your error log and test it out to see what's triggering it.

Did you make any changes prior to this problem? Do you remember the last mod you installed? Try uninstalling the Thank-O-Matic mod to see if it helps.

[Kimmie]

Honestly, I had totally forgotten about this issue, and I am assuming its because I havent seen that error since then and/or because I hadnt had a response since i uploaded that file for [n3rve]

Give me a couple of days (will be busy with family/holiday tomorrow) and I will check on this and close the thread if necessary

[Arantor]

Are you still having trouble with this, or is it resolved now?

[Kimmie]

I havent had the error again so I am gonna assume its fine and will mark solved.

[Arantor]

extremenewbie, is this still an issue?

[rosspet]

I'm getting this error as well with SMF 2.0 RC1.2 . I cleared the error log, went to the home page then back to the error log and found:-

Cleared log, went to moderate then back to log. Six errors, 2 being the same Errors.template.php ones, 2 the same GenericMenu.template.php, and 2 new ones, both Themes/default/ModerationCenter.template.php (body_above sub template - eval?)
Line: 240 and line 239
..................................................

Any ideas please?

[Arantor]

So what mods do you have?

[rosspet]

1.     PortaMx v0.961     0.961
2.    EmailValidator    1.0

[Arantor]

Hmmm.

The problem is that it's not very clear where the errors are. The "eval" part is actually masking where the real error is.

Can you install Disable Template Eval, then tick the box it gives you. This will change the errors so we can see exactly where they are.

[rosspet]

Only one file showing now - Themes/clean/index.template.php lines 239 and 240

[Arantor]

Please can you attach that file here so we can take a look at it?

[rosspet]

OK

[rosspet]

Removed the reference to id_member in lines 239 and 240 as I can't find where it is set. Left template eval disabled, errors gone and all seems to be working OK.
Thanks.

[Arantor]

Interesting. There are two things that should be broken but aren't only on a technicality.

You could replace $context['id_member'] with $context['user']['id'] though which should also fix the issue.

[rosspet]

Thanks Arantor, tried your suggestion, unticked Disable template evaluation, everything works 

[Arantor]

You could leave it ticked, actually. There is a performance boost given too.

[Prosoi]

Hello!

I've same problem on my forum - SMF2.0 RC2. No mods installed.

Very strange. This error in the log came only from one user, a Global Moderator. But other users and Globals - no problem.

I know this is an old topic, but I'm seeing the same behavior. Just upgraded from 1.1.18 to 2.0.4 and I'm seeing this in my log:

same bug... how to fix?

[margarett]

Did you also upgrade from 1.1.x to 2.0.x?

[system1024]

Did you also upgrade from 1.1.x to 2.0.x?

yes - upgrade from 1.1.18 to 2.0.9

[margarett]

This is a known issue (not exactly an issue) and it will be fixed by itself. A quote about this issue:

The variable in question is $_SESSION['ban']['id_member'] - it's the only mention of id_member in that line, so it *must* be that.

SMF 1 to SMF 2 changed how ban-checking per session was done very slightly, the byproduct of which is this error. There's no point fixing it because it's just an extra check that would otherwise need to be carried out every so often, and it's only an issue during the 1.1 to 2.0 upgrade.

Once the session refreshes or the ban check refreshes - whichever first - the new values are generated, and the problem fixes itself. Saying to leave it for an hour simply ensured that the session would be cleared (the default is 20 minutes) so that the new session check would be done that fixed it
