How can I create a new page when I enter a new product in my database, or hide the parameter inside a normal /.../ ?
In this example I will sell Sandles with the product-id 101010
I do not want to use parameters like in the following example:
example.com/shop?productid=101010
But I would like the new page to be
example.com/shop/sandles
First of all you'll need be able to fetch product not by some numeric ID (101010), but by url segment like this 'my-unique-product-name' (upgrade your server side code)
Now you should have something like this working:
example.com/shop?url=my-unique-product-name
then add to your .htaccess something like this:
RewriteRule ^shop/([A-Za-z0-9-_]+])$ shop.php?url=$1 [L]
It tells your server to process URL-s like example.com/shop/my-unique-product-name in a same way as example.com/shop?url=my-unique-product-name, if that makes sense to you.
