301 Redirect issue with existing rule. Please help! thanks

[gevork]

Hi Everyone,

 

Firstly Happy Holidays! :D

 

I was hoping to move some old pages to new ones after a category change using .htaccess

 

here is what i coded;

 

redirect 301 /blue-jeans-p-17.html http://www.domain.com/blue-jeans-different-p-22.html?

 

but this just forwards to this;

 

product_info.php

 

because above in my htaccess I have another rule that is complicating things...

 

RewriteRule ^(.*)-p-(.*).html$ product_info.php?products_id=$2&%{QUERY_STRING}

(I need this rule for my ulitmate seo install)

 

My question is how do I override or sort out this problem so that the old URL's with -p- in them can be forwarded to whatever new urls I want without complications (or going to product_info.php).

 

Many Thanks in advance!!

Have you tried moving your new redirection entry ahead of the old one? It sounds like the old one (pattern: ^(.*)-p-(.*).html$) is being processed before the new one (pattern: /blue-jeans-p-17.html).

I think people use .htaccess and RewriteRules too much it is resource intensive and dangerous if wrong. It is simply done with a small PHP script ..

 

1) Create a new file in catalog/includes/ called redirects.php containing ..

 

<?php
 $redirects = array();
 /**
 * Redirect Seo Uris
 * 
 * The first uri is the target (to be redirected), the second is the actual redirect.
 */
 $redirects['my-old-product-p-2439.html'] = 'my-new-product-p-3938.html';

 $redirects['my-old-category-c-3937.html'] = 'my-new-category-c-4485.html';
?>

 

2) Create a new file in catalog/includes/classes/ called redirects_301.php containing ..

 

<?php
 class redirects301 {

   var $redirects = array();

   function redirects301(){
     if ( is_readable( DIR_WS_INCLUDES . 'redirects.php' ) ){
       include_once DIR_WS_INCLUDES . 'redirects.php';
       $this->redirects = $redirects;
     }
     $this->doRedirects();
   }

   function doRedirects(){
     if ( !empty($this->redirects) ){
       foreach ( $this->redirects as $target => $redirect ){
         if ( false !== strpos( $_SERVER['REQUEST_URI'], $target ) ){
           $this->redirect( $redirect );
         }
       }
     } 
   }

   function redirect( $redirect ){
     $uri = HTTP_SERVER . DIR_WS_CATALOG . $redirect;
     session_write_close();
     header( "HTTP/1.0 301 Moved Permanently" );
     header( 'Location: ' . $uri );
     exit;
   }
 }
?>

 

3) catalog/includes/application_top.php

 

Find ...

 require(DIR_WS_FUNCTIONS . 'html_output.php');

 

Add immediately BELOW ..

 

  // FWR Media 301 redirects
 include_once DIR_WS_CLASSES . 'redirects_301.php';
 $redirects = new redirects301();

 

Now open up catalog/includes/redirects.php and make sure you understand how to create the keys and values of the array in order to create future redirections. Delete the dummy array and put in its place your own.

 

Done ..

 

You can now create product redirects with valid 301 redirection whenever you need to.

A cleaner way of writing the redirects.php array is as follows: -

 

  $redirects = array( 'my-old-product-p-2439.html'] = 'my-new-product-p-3938.html',
                     'my-old-category-c-3937.html'] = 'my-new-category-c-4485.html',
                     'my-old-category-c-57.html'] = 'my-new-category-c-1252.html' );

 

But the one in the script, I believe, the average user would find easier to understand.

Hi Guys,

 

Thank's for you and Phil's responses. Firstly Phil the order doesnt seem to have any effect on how its processed in the .htaccess file.

 

I have created your script and everything worked perfectly until firefox said this;

 

This web page has a redirect loop.

 

The web page at http://www.domain.com/changed-t-shirt-url-p-101.html has resulted in too many redirects. Clearing your cookies for this site or allowing third-party cookies may fix the problem. If not, it is possibly a server configuration issue and not a problem with your computer.

 

explorer stays on an constantly loading white page.

 

a url with a product id that doesn't exist works and redirects like a dream!

 

Turning off the product in admin doesnt work, changing the products id doesnt work.

 

Many thanks in advance,

 

G

No reason at all for this to create a loop

 

The first item in the array (key) should be the target that you wish to be 301 redirected.

 

The second item in the array (value) should be the redirected destination uri.

 

So for example if you had an old product that no longer exists the url of which was ..

 

http://www.mysite.com/catalog/my-old-product-p-23.html

 

And the the new product to be redirected to being ..

 

http://www.mysite.com/catalog/my-new-product-p-85.html

 

the array would be ..

 

  $redirects['my-old-product-p-23.html'] = 'my-new-product-p-85.html';

 

I can't see any reason for a redirect loop in there (unless you have retained the .htaccess redirect)

Hi,

I Just wondered how we would redirect these on a 301 in a similar way:

 

http://www.mysite.co...ex.php?cPath=30

http://www.mysite.co...php?cPath=30_32

http://www.mysite.co...products_id=121

 

I have a few old categories and products I want to get google off and I wish to delete another category and move things around so don't want to be getting 200s when they should be 301s.

 

I didn't want to go to the bother of adding this mod if it will only work on SEO uris....

 

will this work?

 

 
$redirects = array( 'index.php?cPath=30'] = 'index.php?cPath=32',
'product_info.php?products_id=121'] = 'product_info.php?products_id=324' );

 

Thanks

I'm trying to make this work as it seems the cleverest way to deal with the 301s in OsC, however i get this:

 

Warning: session_start() [function.session-start]: Cannot send session cookie - headers already sent by (output started at... etc

 

Any ideas?

 

Thanks
