Multiple Values in RealUrl

Question

When I got multiple values in my URL of the same name
e.g …&tx_myext_pi1[crit][]=1&tx_myext_pi1[crit][]=2…
and I want to have it multiple times in my RealUrl-ified URL
like …/crit/title-of-crit-1/crit/title-of-crit-2…
it's not working.
I only get …/crit/title-of-crit-1… and …/crit/title-of-crit-2… is missing

…&tx_myext_pi1[crit][]=1…
translates to …/crit/title-of-crit-1/… and
…&tx_myext_pi1[crit][]=2…
translates to …/crit/title-of-crit-2/… so that part is working. But not multiple values.

Is this impossible to do with RealUrl? Should I make a userFunc? How?

My RealUrl Conf

// …
'postVarSets' => array(
    '_DEFAULT' => array(
        'crit' => array(
            array(
               'GETvar' => 'tx_myext_pi1[crit][]',
               'lookUpTable' => array(
               'table' => 'tx_myext_domain_model_crit',
               'id_field' => 'uid',
               'alias_field' => 'title',
               'languageGetVar' => 'L',
               'languageExceptionUids' => '',
               'languageField' => 'sys_language_uid',
               'transOrigPointerField' => 'l10n_parent',            
               'autoUpdate' => 1,            
           ),
       ),
    ),
),
// …

Answer 1

Is this impossible to do with RealUrl?

Yes, is impossible to achieve this using RealUrl. The problem is that you are using array in the query string.

Answer 2

You can merge your values in one string

Like this:

/crit/title-of-crit-1,title-of-crit-1

Or

/crit/title-of-crit-1+title-of-crit-1

And split it when you need. by , Or + or another special character.

For example Drupal uses this rule for multiple values in views moudle.
