TYPO3和RealURL的混合语言网址

Question

I have setup RealURL for generating the url's but it is generating mixed language url's after changing the language. After clearing cache and don't changing language the urls stay in the active language, no problem. But after changing the language the url's become mixed. The language preset and page name stay correct but the description is a mix between two languages. For example the link urls below are generated on the same page:

/de/anzeige/kategorie/1/vorrat/all.html (this is correct)
/de/anzeige/categorie/1/voorraad/all.html (mix between german & dutch)

Looks like a cached problem? I fixed it now by making all combination between the languages in the realurl config file, but this makes the file to complex.

In the realurl config file I'm using the following code in the beginning to do the languages selection:

$lang = substr($_SERVER['REQUEST_URI'], 1, 2);

if($lang=='de') {
    $cat = 'kategorie';
    $alias = 'COALESCE(name_de, name_en, name_nl)';
}
else {
    $cat = 'categorie';
    $alias = 'COALESCE(name_nl, name_en, name_de)';
}

This part is used in the postVarSets to get the category name from the database. Could it a problem on how I get the category name from the database?

$cat => array(
     array (
         'GETvar' => 'extension[catname]',
                    'lookUpTable' => array (
                        'table' => 'database_table',
                        'id_field' => 'uid',
                        'alias_field' => 'uid',
                        'addWhereClause' => ' AND NOT deleted',
                        'useUniqueCache' => '1',
                        'useUniqueCache_conf' => array (
                            'strtolower' => '1',
                            'spaceCharacter' => '-',
                        ),
                    ),
                ),
                array (
                    'GETvar' => 'extension[catname]',
                    'lookUpTable' => array (
                        'table' => 'database_table',
                        'id_field' => 'uid',
                        'alias_field' => $alias,
                        'addWhereClause' => ' AND NOT deleted',
                        'useUniqueCache' => '1',
                        'useUniqueCache_conf' => array (
                            'strtolower' => '1',
                            'spaceCharacter' => '-',
                        ),
                    ),
               ),
         ),
   ),

Answer 1

It looks like you did not create a translation of your actual page in the page tree. The language identifier is still "de" in both of your links. So first step is to create a translation.

Next step is to make your extension support multiple languages, which will add some language_* fields to your table. If done correctly, you can created translations of your categories without having multiple languages in one database record. You will end up with having one record per language.

Next, you need to add the language config to your realurl config like in the news extension :

    array(
            'GETvar' => 'tx_news_pi1[news]',
            'lookUpTable' => array(
                'table' => 'tx_news_domain_model_news',
                'id_field' => 'uid',
                'alias_field' => 'title',
                'addWhereClause' => ' AND NOT deleted',
                'useUniqueCache' => 1,
                'useUniqueCache_conf' => array(
                    'strtolower' => 1,
                    'spaceCharacter' => '-',
                ),
                'languageGetVar' => 'L',
                'languageExceptionUids' => '',
                'languageField' => 'sys_language_uid',
                'transOrigPointerField' => 'l10n_parent',
                'autoUpdate' => 1,
                'expireDays' => 180,
            ),
        ),

Then you're done :-)
