[MODx] 10. Using Babel for Muti-languages support

1. Go to 'Extras' -> download and install 'Babel'.

2. Set up '.htaccess' file, currently, we set up three languages:

find '# The Friendly URLs part' in your .htaccess / ht.access file, replace the existing code with:

# The Friendly URLs part
# redirect all requests to /de/favicon.ico and /nl/favicon.ico
# to /favicon.ico
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(en|nl|de)/favicon.ico$ favicon.ico [L,QSA]
                          
# redirect all requests to /de/assets* and /nl/assets* to /assets*
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(en|nl|de)/assets(.*)$ assets$2 [L,QSA]
                         
# redirect all other requests to /de/* and /nl/*
# to index.php and set the cultureKey parameter
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(en|nl|de)?/?(.*)$ index.php?cultureKey=$1&q=$2 [L,QSA]

Basicly, it just redirect to favicon, assets folder & index.php to root directory.

Then if you have ht.access, you need to delete it and replace with .htaccess.

3. Go to system setting, set 'Use Friendly URL' to 'YES':

4. Create a new plugin call 'gateway':

<?php
        if($modx->context->get('key') != "mgr"){
            /* grab the current langauge from the cultureKey request var */
            switch ($_REQUEST['cultureKey']) {
                case 'nl':
                    /* switch the context */
                    $modx->switchContext('Nederlands');
                    break;
                case 'de':
                    /* switch the context */
                    $modx->switchContext('Deutsch');
                    break;
                default:
                    /* Set the default context here */
                    $modx->switchContext('web');
                    break;
            }
            /* unset GET var to avoid
             * appending cultureKey=xy to URLs by other components */
            unset($_GET['cultureKey']);
        }

5. Then click 'System Events' tab, scroll down to 'OnHandleRequest', select the checkbox.

6. Go to system -> 'Contexts', add two contexts 'Deutsch' & 'Nedelands':

7. In Context, right click 'Web', select 'update context', then clicik 'context settings' tab:

8. Add setting to it:

7. In 'Access Control List', right click the '(anonymouse)', select 'Update user group':

8. Reinstall the Babel to add de & nl into the language.
