Get fatal error after when click enable

geexis

I am getting this "The addon could not be enabled because it generated a fatal error:" when trying to enable it.

Linc

What's the error?

hgtonight

If there is no error listed, right click on the enable button and open in a new tab. It should show up then.

hi, I am getting
Parse error: syntax error, unexpected T_FUNCTION in /.../forum/plugins/QnA/class.qna.plugin.php on line 415
Version 2.0.18.11
and latest v.1.2.1 QnA

peregrine

I don't get the error in 2.1, but I use php 5.3

Is there any reason why you don't upgrade to 2.1 and php 5.3 as well, eventually you will need to upgrade to 2.1 since it will be phased out in a year and you might as well use 2.1 if you can (alot more features available).
and php 5.3 and above have more functionality.

   $Comments = $Sender->Data['Comments']->Result();
         $Comments = array_filter($Comments, function($Row) {
            return strcasecmp(GetValue('QnA', $Row), 'accepted');
         });

what version of php do you use? probably more related to php version rather than vanilla version.

peregrine

PHP is older than 5.3. Anonymous function support wasn't available until 5.3

peregrine

you might need to change it to something like this for older php

I haven't tested it...
change from:

   // Remove the accepted answers from the comments.
      if (isset($Sender->Data['Comments'])) {
         $Comments = $Sender->Data['Comments']->Result();
         $Comments = array_filter($Comments, function($Row) {
            return strcasecmp(GetValue('QnA', $Row), 'accepted');
         });
         $Sender->Data['Comments'] = new Gdn_DataSet(array_values($Comments));
      }
   }

to

              // Remove the accepted answers from the comments.
              if (isset($Sender->Data['Comments'])) {
                 $Comments = $Sender->Data['Comments']->Result();
                 $Comments = array_filter($Comments, $this->ReturnValue($Row));
                 $Sender->Data['Comments'] = new Gdn_DataSet(array_values($Comments));
              }
           }


     public function  ReturnValue($Row) {
                return strcasecmp(GetValue('QnA', $Row), 'accepted');
             }

yes, I'm thinking about 2.1 but need to check rest of plugins before..
my previous version 1.0.8b now works just fine

peregrine

once again WHAT PHP version??? are you using.

even if you upgrade to vanilla 2.1 - you would still get error unless you modify code or upgrade to php 5.3

peregrine

see the changelog on this link.

http://php.net/manual/en/functions.anonymous.php

if you download the version check plugin - you can easily see what version of php you have.

or type php -v at the command line

really!

you should be able to change to 5.3 in cpanel or ask your host.

or try the code changes I suggested.

peregrine

@linc - this addon requires php 5.3 yet vanilla requirements are 5.2 for vanilla 2.1 and below !

grun

the changes above for 5.2 PHP works fine
many tnx!!!

Linc

Ah, looks like Todd got a little ahead of things and created a closure. Hm. I think I may need to branch the addons repo.

may be its a reasonably for older PHP versions, but I'll try to change for 5.3 anyway
thanks again!

Linc

I've branched addons so we can change Q&A to work with 2.1.

I am using PHP 5.3 and vanilla 2.1 stable. I was still unable to enable the plug-in

what version does the q&a plugin say for you @gexis? did you get it from github?

available from here:
https://github.com/vanilla/addons/tree/2.1

If you still get and error:

for debugging purposes only

you can enable and force the plugin to TRUE in your config.php by adding the line below or changing tot TRUE (if the line exists).

$Configuration['EnabledPlugins']['QnA'] = TRUE;

generally you don't want to force if you are not debugging (if the plugin won't enable via dashboard)

and also change

$Configuration['Debug'] = TRUE;

then report the error you get.

if you get the same error as above , then make these changes.
