  Hello,
  
  If you want to create cron you need to create a script with query from post above, eg. create_friendly_url.php
  Next add executing of this file in cron like this: php /path/to/file/create_friendly_url.php
  
  Maybe my module will help you: https://github.com/evox95/mbgplr
  
  If you want me to write such a cron task for you, write to me: contact@bestcoding.net
  
  Regards

Hello,
Thank you for your article.
Would you have the same query to update all descriptions produced from one language (FR id 1) to all other languages (X6)?
Thanks

Hello,
Thanks again for your scripts!
I have a problem with your module that generates the product URLs.
When a product has a character accented in its name (French name), the rewritten url stops literally before that accent.
Do you have a solution to avoid this problem?
Thank you in advance.

In fact, it’s the apostrophes that are problematic …
Ex: name of product is VEILLEUSE PROJECTEUR D’ÉTOILES
and the url rewrite is truncated before ‘ÉTOILES
Would you have a solution?

  Have you tried using the above query instead of the module?

That’s not it yet …
The problem is accentuated uppercase characters

Reply
Bruce says:

15/11/2017 at 17:33

yes it’s the same result
My product name is : VEILLEUSE PROJECTEUR D’ÉTOILES
And the URL friendly is (with your module or your sql code) : veilleuse-projecteur-d
I would like URL friendly : veilleuse-projecteur-d-étoiles

Thanks

  Hello,
  My script removes everything which is not not number (0-9) or small letter (a-z) and replaces uppercase letters (A-Z) into lowercase (a-z).
  I think it’s not a good idea to have accented characters in URL.
  If you want I can add replacing accented characters into standard ASCII characters (a-z).

“If you want I can add replacing accented characters into standard ASCII characters (a-z).”

Yes, I would like it if you do not mind. 🙂

At worst, we turn uppercase accented characters letters into lowercase characters not accented

Hello,
I try this :
IF i >= 192 AND i <= 223 THEN
ITERATE label;
END IF;
But is not good 🙁
Product name : POKÉBOX NOËL 2017
Url rewrite : pokÉbox-noËl-2017
I would like : pokébox-noël-2017 or pokebox-noel-2017

Thanks
