Wordpress Themes - WP Forum at BFA
There will be no more development for Atahualpa (or any other theme), and no support. Also no new registrations. I turned off the donation system. I may turn the forum to read only if it gets abused for spam. Unfortunately I have no time for the forum or the themes. Thanks a lot to the people who helped in all these years, especially Larry and of course: Paul. Take care and stay healthy -- Flynn, Atahualpa developer, Sep 2021

style import causes php error

Hi,

after some playing around with my local test system, I decided to start installing the soon to be productive wordpress installation. So far I am running

WP 2.9.2
ATA 3.5.3
I have made several changes to the styling on my local installation. To reuse them, I exported them into an ata_XXXX_.txt file. I can also succesfully import this file into the WP installation on my server.

The problem is, that after the import the wordpress installation goes dead, i.e. I only get a blank screen, the HTTP response is zero bytes.

I have checked the logs of the server and I see the following error:

Code:
[Thu Oct 14 21:37:26 2010] [error] [client XXXX ] PHP Fatal error:  Cannot use object of type stdClass as array in /var/www/domain/htdocs/wordpress-2.9.2/wp-content/themes/atahualpa353/functions/bfa_theme_options.php on line 29
As said before - when I do not import the settings, everything is fine. Afterwards things break.

I will also attach the exported style file. Maybe this can help somehow.

Can anybody give me a hint as to what might cause this?

bye, Grimmi

ust imported it and it works fine. one difference, I'm on wp 3.0.1 not sure if I have any test 2.9.2 versions around...I'll look
Can you swap back to the defaule theme (go into the Atahualpa folder and rename index.php to index.old - then go to dashboard->appearances->themes and it should switch to the twenty-ten theme) Then rename index.old back to index.php and try activating atahualpa again.

I will try this on the weekend.

Out of interest: What version of PHP is your system running?

I am wondering if it might be a compatiblitiy issue between php versions.

Test system (where everything works): PHP 5.3.3
Prod system (where things fail): PHP 5.2.11 + Suhoshin(?)

I have started some debugging of this issue. By adding a var_dump like this in line 29:

Code:
$bfa_ata = get_option('bfa_ata4');
echo "<pre>";
var_dump($bfa_ata);
echo "</pre>";
I get an output starting with this for $bfa_ata:

Code:
object(stdClass)#114 (267) {
  ["use_bfa_seo"]=>
  string(2) "No"
  ["homepage_meta_description"]=>
  ...
EDIT:
The output from my dev system for this is:

Code:
array(267) {
  ["use_bfa_seo"]=>
  string(2) "No"
  ["homepage_meta_description"]=>
  string(0) ""
  ...
So, to me it seems like the error message as showed in my initial statement indeed is correct. The result of the get_option call is NOT an array, but an object. So it is reasonable that the following:

Code:
$bfa_ata_widget_areas = $bfa_ata['bfa_widget_areas'];
causes such an error, because it treats $bfa_ata like an array.

That still leaves me wondering why I don't see this on my test system. But at least it seems like this is a bug. Anybody with more PHP/atahualpa development experience who would like to give a statement on this?

OK, taking this further: If I change this to the correct OO syntax, i.e.

Code:
$bfa_ata_widget_areas = $bfa_ata->bfa_widget_areas;
The error is gone. Next error up ahead is:

Code:
[Fri Oct 15 17:42:18 2010] [error] [client 79.196.247.50] PHP Fatal error:  Cannot use object of type stdClass as array in /var/www/vierpfeile/htdocs/wordpress-2.9.2/wp-content/themes/atahualpa353/functions/bfa_get_options.php on line 526
There I can see the same problem. But in fact, the whole code uses the array syntax on $bfa_ata. So I do not believe that this is the real problem.

Question: Given the very "mutating" history of PHP - Does anybody know if this is another episode of the ever-changing PHP??? Maybe there's some kind of switch that forces my production system to behave like this?

BTW - now that I am back in front of the system: The exact version of the prod system's php is:

PHP Version 5.2.12-pl0 with suhosin 0.9.7

Maybe there are some known issues with this combination?

Well I just went back and did a test on a WP 2.9.2 and Atahualpa 3.5.3 and export/import works fine. This is with php 5.2.9

I added the
HTML Code:
echo "<pre>";
var_dump($bfa_ata);
echo "</pre>";
and I get an Array out.

So it seems that this is an environment issue. On one of your systems (and on two of mine), the line
HTML Code:
$bfa_ata = get_option('bfa_ata4');
returns an array and on the other it returns an object.

so we have
php 5.2.9 - returns an array
php 5.2.12-pl0 - returns an object
php 5.2.13 - returns an array
php 5.3.3 - returns an array

Thanks for investigating, Juggledad.

To be more precise, we have

So, to me the most likely culprit is suhosin. I will try to check this out further and report my findings.
