Wikka: Fatal error: Call to a member function on a non-object

Fatal error: Call to a member function on a non-object

Description of the problem

Received this error today (march 25 2005)

Fatal error: Call to a member function on a non-object in /var/www/emp.empornium.us/wikka/formatters/wakka.php on line 186

I had copied the FormattingRules page to my own wiki (you really should include it with your install). I disabled html embedding in wiki pages in the wikka.config.php with the line

"double_doublequote_html" => "disabled",

i deleted a section at the end of FormattingRules wherei guess a cohort had included brief html embed instructions. When i clicked Store, the resulting page (which would have displayed the complete edit) gave the above error.

It's wierd because any attempt EXCEPT by /edit to parse that page at all results in that error. Even history.

I discovered that the error occurs on use of double double quotes to escape from the wikitext renderer. We run with magic quotes off, but adding set_magic_quotes_runtime(1); to the top of formatters/wakka.php produced the same error

Suggestions?

Yes, that is what happened. Do you know of any way other than

&quot

to use quotes in wikka without them appearing as question marks? --Jmax1632

Possible solution

It might help to change the
$allowed_double_doublequote_html = $wakka->GetConfigValue("double_doublequote_html");

to
$allowed_double_doublequote_html = $this->GetConfigValue("double_doublequote_html");

or
$allowed_double_doublequote_html = $wakka->config["double_doublequote_html"];

in formatters/wakka.php. This just a blind guess though. -- TimoK
- Ok, I just tried some things on my own wikka - the first change most propably doesn't change anything for you, since it produces the error you get when I make it. On further thinking (aka after some coffein) it was really stupid, since there is no $this at that place. Question: Does GeShi work for you? Or using % % without the space at all? (Please test on a simple page with no html or anything else, just one line of to-be-hilighted code) -- TimoK
  - It seems the
    global $wakka;
    
    is ignored. I found a similar problem here∞ and it was beeing solved by globaling the object before its creation and not creating it by reference. Applied to wikka this means you need to go into your wikka.php and change the line
    $wakka =& new Wakka($wakkaConfig); # create object by reference
    
    to
    $wakka = new Wakka($wakkaConfig); # create object NOT by reference
    
    and add a
    global $wakka;
    
    in front of it. (Sorry for needing three edits to come up with this, I just shouldn't try to solve problems I can't 'live-test' that early in the morning.) -- TimoK

Solution

When "double_doublequote_html" => "disabled" configuration is set, the current version of wikka then refers to the incorrect class when parsing ddq.

FIND in formatters/wakka.php

return $this->htmlspecialchars_ent($matches[1]);

REPLACE WITH

return $wakka->htmlspecialchars_ent($matches[1]);

This statement is never touched as long as "double_doublequote_html" => is not set to "disabled"

Thanks JavaWoman for your solution, thanks TimoK for trying.

Ah well, I should stick to those things I can test or where I know the code 100% :) --TimoK
