[Resolved] Calling icl_get_languages causes crash in wordpress 3.5

This is the code i use in my functions.php

define( 'TEMAURL' , get_bloginfo( 'template_url' ) );
define( 'ABSTEMA' , dirname( __FILE__ ) );
define( 'SHORTNAME' , strtolower( substr( get_bloginfo( 'name' ) , 0 , 1 ) . substr( get_bloginfo( 'name' ) , -1 ) ) );
define( 'THEMENAME' , get_bloginfo( 'name' ) );
define( 'ARRAY_LANG' , serialize( icl_get_languages() ) );
add_theme_support( 'post-thumbnails' );
add_post_type_support('page', 'excerpt');
register_nav_menu( 'topmenu', 'Top Menù' );

If i comment this out

define( 'ARRAY_LANG' , serialize( icl_get_languages() ) );

everything is going to work fine.

Thanks Harshad for your reply:

i did exactly what you said to do, and the only output in error_log.txt is

[18-Dec-2012 13:59:04 UTC] PHP Notice:  Undefined index: name in /web/htdocs/www.enuage.it/home/wp-includes/query.php on line 3569

That output is also visible when wp_debug is set to true.

If it can help you, im going to attach my home status when icl_get_languages is declared and when it is commented out.

Hi Harshad,

unfortunately i can't give you those details, but i can give you some information about debugging:

I tried WP 3.4.2 with the latest version of wpml and string translator, and it works fine.

Upgrading WP from 3.4.2 to 3.5 causes the crash of the frontend when i declare that define.

I suppose, then, some incompatibility with the new WP.

I'll attach my results as image and i'll send to your email the theme i'm using.

Ok, with the new version you sent to me, it doesn't crash in 3.5

Hovewer icl_get_languages() returns " a:0:{} " when defined in functions.php, but i guess it's not a big problem to solve

The theme is always the same.

I'll attach the output.

I switched to Twenty Twelve and added that code in functions.php of the theme itself at the very top ( as you can see in the attachment) ; the output is the same: " a:0:{} "

Very very strange. I've installed wp 3.5 and just wpml on a remote server ( maybe wamp was not configurated properly ) and still that array is empty.

However i find that declaring

define( 'ARRAY_LANG' , serialize( icl_get_languages() ) );

outside functions.php ( like header.php ) , makes

print_r( ARRAY_LANG )

to work fine.

Also i tried this, in function.php this time:

function test(){
if( function_exists( 'icl_get_languages' ) )
	define( 'ARRAY_LANG ' , serialize( icl_get_languages() ) );
}
add_action('wp_head','test');

and in this case the array is NOT empty.

My issue is half resolved, by the way

Well, at the moment i can use the serialized array only when it is declared into an output hook, such as wp_head.

However declaring that costant inside functions.php, without any hook, or if i use other hooks, such as init o after_theme_setup, it doesn't make the array to be assigned

This is my screenshot.
