Apache Mod Rewrite old URL pattern to new one

Question

I'm newbie in Apache Mod Rewrite stuff, I need help to write a rule:

Old pattern:

/{category_id}/{from}/{category_slug}-{page}/{id}/detail-{slug}

New pattern:

/{category_id}-{from}-{category_slug}/{id}-{slug}

The REGEX rules for params are:

    id:             \d+
    category_id:    \d+
    slug:           "^[a-z0-9-]+"
    category_slug:  "^[a-z0-9-]+"
    from:           "^[a-z0-9-]+"
    page:           \d+

I need to write the .htaccess rule to automaticaly redirect old pattern URLs to new ones with a permanent redirect 301.

Example Old URL:

/2/categorie/tables-bureaux-1/213/detail-secretaire-des-annees-60-domino

Expected new URL:

/2-categorie-tables-bureaux/213-detail-secretaire-des-annees-60-domino

For the moment, I've tried this but it doesn't work:

RewriteCond %{THE_REQUEST} /([0-9]+)/([a-z0-9-]+)/([a-z0-9-]+)-([0-9]+)/([0-9]+)/detail-([a-z0-9-]+) [NC]
RewriteRule /%1-%2-%3/%5-%6$ [R=301,L]

I'm using the PHP Symfony2 framework which already have this .htaccess rule - so I'm not sure where to write the new one:

RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*)$ app.php [QSA,L]

Thanks for your help.

Try this simplified rule:

RewriteCond %{THE_REQUEST} /([0-9]+)/([a-z0-9-]+)/([a-z0-9-]+)-([^-]+)/([0-9]+)/detail-([^\s?]+) [NC]
RewriteRule ^ /%1-%2-%3/%5-%6? [R=301,L,NE]

Make sure this rule is placed as very first rule in your main .htaccess file.
