qTranslate – Notice: Undefined index

Hi Ruson,

Patch is a command-line utility: https://en.wikipedia.org/wiki/Patch_%28Unix%29

I do not use patch from the command line, so I cannot help you with that. You can use this patch by just looking at the code changes it makes in the actual text of the patch (compare the + and – lines). Or you could use a text-editor with patch capabilities. I use Eclipse to this end.

The patch you mentioned does have a minor flaw: the function should return $locale and in the patched version it does not.
I have added a different patch to address the notice you found:

Does not help!

Notice: Undefined index: language in wp-content/plugins/qtranslate/qtranslate_hooks.php on line 148

I think the other parts of the patch you mentioned earlier needs to be applied too. I had a quick look at those and thought they were OK.

This problem was because of plugin W3C total cache, when i deleted it everything ok.

After installing WP Super cache the same problem =(

This is a strange issue; I had qtranslate working for some months. Today I disabled the plugin temporarily and when re-activating the plugin the mentioned “undefined index” notices start to pop up…

My solution/suggestion is to modify the qtranslate_hooks.php and call qtrans_init() when required. Like this:

(Starting at line 104)

function qtrans_useCurrentLanguageIfNotFoundShowAvailable($content) {
	global $q_config;
	// Add the following line:
	if( !isset($q_config['language']) ) qtrans_init();
	return qtrans_use($q_config['language'], $content, true);
}

function qtrans_useCurrentLanguageIfNotFoundUseDefaultLanguage($content) {
	global $q_config;
	// Add the following line:
	if( !isset($q_config['language']) ) qtrans_init();
	return qtrans_use($q_config['language'], $content, false);
}

Reason:
This warning occurs, when another plugin calls any of the filters that are hooked to qtrans_useCurrentLanguageIfNotFoundUseDefaultLanguage before the plugins_loaded action is called (like a plugin calling the bloginfo() function when it is loaded)
There should be no problem with the fix I post above, since the qtrans_init method will only execute the first time is is called

after adding this code just white screen and

Fatal error: Cannot redeclare qtrans_useCurrentLanguageIfNotFoundShowAvailable() (previously declared in /home/domains/public_html/wp-content/plugins/qtranslate/qtranslate_hooks.php:104) in /home/domains/public_html/wp-content/themes/evroluxe/functions.php on line 334

Ruson: The functions already exist, what I did mean is to only add this one line inside the both functions:

if( !isset($q_config['language']) ) qtrans_init();

(The rest of the code is just to tell you where to add this line)

Oh yeah, you are right, but I got another problem after adding the code…

Fatal error: Call to undefined function wp_get_current_user() in /home/evroluxe/domains/evroluxe.com/public_html/wp-includes/capabilities.php on line 1342

Hi all,

I have problems translating content on pages (edit page). It won’t update what I am translating? I don’t have any problems when it is a post I want to translate.

I blame my lack of experience working with WP. Tried debugging all day until this post.

FYI I have the latest updates of both qtranslate and WP.

Thanks

This was extremely helpful, cheers guys. Wish this issue would be fixed in the plugin update.
