Yii2 301 redirect from raw url to SEO-friendly url in .htaccess doesn't work, need other solution

Question

I have site based on Yii2 advanced template, made for replacing old site that cannot be optimized for SEO.

SEO-friendly urls are enabled in Yii2's urlManager configuration.

For SEO purposes I should write near 20 301 redirects from old site for urls with raw query string with structures:

/index.php?p=var
/index.php?p=open_cat&cat_id=55

to SEO-friendly urls ('contoller','action','alias' are variables):

/controller/action/alias

I have tried:

In frontend/web/.htaccess:

RewriteEngine on

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d

Redirect 301 /index.php?p=open_cat&cat_id=55    http://example.com/controller/action/alias

RewriteRule . index.php

This method didn't work, page with /index.php?p=open_cat&cat_id=55 url responds 404 error.

In frontend/web/.htaccess:

RewriteEngine on

RewriteCond %{QUERY_STRING} p=open_cat&cat_id=55
RewriteRule ^index.php$ /controller/action/alias [L,R=301]

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d

RewriteRule . index.php

This method appends full path of index.php with raw route:

http://example.com/path-to-file-from-server-root/app/frontend/web/index.php?r=controller/action/alias

I don't know how to write correct redirect with Yii2 methods for raw url. Also problem is that old and new urls have nothing in common. I search unified solution for all redirects, because new urls are associated with different actions and controllers.

I would be glad for hint or solution. Thank you!

Thank you, but problem was from another side - pretty URL's are already configured on my site, I could not write correct rule in htaccess. Seems that solution is in redirect via headers in php code. — Daria Motorina, Jul 17 '16 at 17:44

Solution was taken from answer on this question.

I've created component RedirectComponent, included in frontend\config\main.php in components and bootstrap arrays:

<?php $params = array_merge(
    require(__DIR__ . '/../../common/config/params.php'),
    require(__DIR__ . '/../../common/config/params-local.php'),
    require(__DIR__ . '/params.php'),
    require(__DIR__ . '/params-local.php') );

return [
    'id' => 'app-frontend',
    'basePath' => dirname(__DIR__),
    'homeUrl' => '/',
    'bootstrap' => ['RedirectComponent','log'],
    'controllerNamespace' => 'frontend\controllers',
    'components' => [
        /* */
        'RedirectComponent' => [
            'class'=>'frontend\components\RedirectComponent',
        ],   
    ],
    'params' => $params, 
];

I've created method init() in RedirectComponent class (not sure in necessity on parent::init() in it):

public function init()
{
      /*redirect logic*/ 
}

I couldn't redirect to proper location via redirect() method, called through dynamically created controller and action, so I've redirected via native php header() function.
