Correct url rewriting rule for .htaccess? - php

I have a webshop in asp language that will be renewed to a php webshop. There are still many url's and links from the old webshop stored on different websites that I want to revert to the homepage of the new webshop.I'm looking for example for the correct rule to redirect the following url in my .htaccess file:
http://www.example.com/shopdisplayproducts.asp?id=15&cat=football to http://www.example.com
Could you show me this example, so I might be able to make the other redirects myself.
I have tried for example this, but without success:
RewriteRule ^shopdisplayproducts* index.php [R=301,L]
Thanks for your input
Regards,
Vicef

If you want a catch-all URL that will match regardless of the query string you could use
Options +FollowSymLinks -MultiViews
RewriteEngine On
RewriteRule ^shopdisplayproducts\.asp / [L,R=301]
If you want to match the query string as well you need to add two lines
Options +FollowSymLinks -MultiViews
RewriteEngine On
RewriteCond %{QUERY_STRING} id=15
RewriteCond %{QUERY_STRING} cat=football
RewriteRule ^shopdisplayproducts\.asp / [L,R=301]
While testing it's better to use R=302 instead of R=301 because browsers cache 301 responses, so if you change the rule you won't see the effect because the browser is still executing the cached result. When you use 302 you don't have this problem. So start with 302 and once it works replace that with 301.
Also, please be aware that redirecting everything to the homepage of a new site is almost never a good idea in terms of SERP ranking. If there is a new URL for a certain page it's better to rewrite to that URL. If there isn't, you might want to consider just letting it 404 so search engines will just remove them from their results.

htaccess redirect in wordpress

By using WordPress with Divi and custom php pages/scripts I ended with urls looking like this:
https://example.com/?day=today
https://example.com/?sport=1&league=123 (1=football and 123=premier_league)
I want to make them more user and SEO friendly and rewrite them in htaccess to:
https://example.com/?day=today ==> https://example.com/today
https://example.com/?sport=1&league=123 ==> https://example.com/football/premier_league
For the "day" link I tried this code, but it doesn't work
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^([0-9a-z\-\_]+)?$ /?day=$1 [L,QSA,NC]
</IfModule>
For the other example with sport and league I wanted to find a solution in which I will manually add old link and new link, tried redirect 301, but I think it can't work, right?
Redirect 301 https://example.com/?sport=1&league=123 https://example.com/football/premier_league
I also tried Redirection plugin in WP, but it created Rule which destroys page and makes error 500:
RewriteRule ?sport=1&liga=123 https://example.com/football/premier_league [R=301,L]
or
RewriteCond %{QUERY_STRING} ^sport=1&league=123$
RewriteRule ^$ https://example.com/football/premier_league [R=301,L]
which gaved address: https://example.com/premier_league/?sport=1&league=123
I was also wondering if I can make it with pure php, since in PHP I can easilly get proper strings for id's of the sports and leagues. Unfortunantelly changing "?sport=1&league=32758" into "?sport=football&league=premier_league" and then clean it with rewrite in htacces is not possible right now.
I'm not expecting whole code for both problems, I believe that some directions would be enough. I browse stack and google and coudn't find any examples with links that looks like mine, so example.com/?sport=1 not example.com/page?sport=1
After further investigation I believe the problem is in the way I'm opening my custom pages. I'm using shortcodes to initiate a script and inside the script my php code is included with parameters. I think that because of that I got to this page https://example.com/premier_league/?sport=1&league=123 which was pretty close, but not working.
Now my question is how to send those parameters to proper script but not into url.

301 redirect & htaccess RewriteEngine conflicting

My site uses RewriteEngine to hide variables in the URI as follows:
RewriteRule ^([^/\.]+)/?/([^/\.]+)/?$ page.php?theme=$1&pg=$2 [L]
This works fine, but as we're relaunching, we've got a few 301 redirects to handle as well. I've added these below my rewrite rules, here's an example:
redirect 301 /about/about-the-site https://www.mywebsite.com/about-us
The problem is, that it's redirecting but adding extra crap to the url string:
https://www.mywebsite.com/?theme=about&pg=about-the-site
Any idea why this would be happening?
Don't mix mod_alias and mod_rewrite rules as these 2 modules execute at different stages. Keep everything in mod_rewrite itself:
RewriteEngine On
RewriteRule ^about/about-the-site/?$ https://www.mywebsite.com/about-us? [L,NC,R=301]
RewriteRule ^([^/.]+)/?/([^/.]+)/?$ page.php?theme=$1&pg=$2 [L,QSA]
Also note extra ? in the target URL to strip any pre-existing query string. Make sure clear browser cache while testing it.

.htaccess RewriteEngine converting links without changing links

I'm on my begining of learning PHP and very first steps of .htaccess, most of my new web is about main category and few subcategories.
Here are links examples i had before working out .htaccess RewriteEngine:
example.com/index.php?cat=email
example.com/index.php?cat=about&show=some
with help of .htaccess RewriteEngine i've convered them to:
example.com/email/
example.com/about/some/
Here is part of .htaccess:
RewriteRule ^([A-Za-z0-9-]+)/$ index.php?cat=$1 [L]
RewriteRule ^([A-Za-z0-9-]+)/([A-Za-z0-9-]+)/$ index.php?cat=$1&show=$2 [L]
RewriteRule ^([A-Za-z0-9-]+)$ index.php?cat=$1 [L]
RewriteRule ^([A-Za-z0-9-]+)/([A-Za-z0-9-]+)$ index.php?cat=$1&show=$2 [L]
Now problem is that most of content have inside links like: "example.com/index.php?cat=about&show=some" Changing them all is option, but anyway... is there anything else could be done? I heard of some .htaccess option that autoconverts links to format you need without changing them manualy, so all links in PHP pages will be the same, but once user gets page loaded, links will be like (example.com/about/some/) Is there anything like that, or is there any other option to leave original link without changing them all?
Cheers!
Links on your site are created with your PHP scripts, Apache with htaccess can't magically change all this links in a raw.
Now what you can do, is redirect old URL to the new ones using htaccess, with a 301 redirection.
For example, if someone click on example.com/index.php?cat=email, Apache will redirect (= the URL will be changed and there will be another HTTP request) to example.com/email/, and then rewrite this to index.php?cat=email
Add this to your htaccess :
RewriteCond %{REQUEST_FILENAME} index.php$
RewriteCond %{QUERY_STRING} cat=([a-zA-Z0-9-]+)
RewriteRule ^ http://example.com/%1/? [L,R=301]
Anyway I strongly recommend you to change the links directly in your code, because even if the solution I've just explained should works (not tested), it's not really healthy to use redirection when you can avoid them.

Rewrite URLS in Wordpress site

I have some old SWF that has fixed links inside, so I need to rewrite all the links to redirect to new site I build on Wordpress.
I actually need to redirect all links that have FID=<123> to /me_<123> (that's the permalink I created for all pages I need to redirect)
For example:
http://kavor.org.il/KavOr07/Templates/showpage.asp?DBID=1&LNGID=2&TMID=843&FID=1997
Needs to go to http://kavor.org.il/me_1997
I tried to put this in .htaccess:
^FID=([^/.]+)/?$ /me_$1 [R]
but it has no effect and also for some reason slows down the entire site loading.
I know that Wordpress has its own rewrites so maybe it's interefering.
I would be glad for some help with that I got pretty lost in all the mod_rewrite rules...
To match query string you will need a RewriteCond with %{QUERY_STRING}
Try this rule:
RewriteCond %{QUERY_STRING} (^|&)FID=([^&]+) [NC]
RewriteRule ^KavOr07/?$ /me_%1? [L,R=302,NC]

Forcing urls to rewrite/redirect?

This rewrite methode works, but its not Forcing urls to rewrite/redirect to the new urls.
I use this:
RewriteEngine on
RewriteRule ^page/([^/\.]+)$ search.php?q=$1
i can access rewrited urls (project/page/etc..) , but old urls/links (search.php?q=etc) still accessible without redirect.
note: i use $_SERVER variants to creating urls, and on localhost.
You have to rewrite project/page to search.php? in order to hide the ugly urls.
And redirect search.php? to project/page in order to make the canonical urls the only way to access that resource.
In your code there is no mention of the redirect, you're just rewriting.
Think of it this way
rewrite hides the ugly urls behind canonical urls (it hides them, it doesn't eliminate them);
redirect responds to the browser with a message like "search.php? has moved to project/page, try that link instead" and the browser follows the new link;
To redirect so called ugly URLs to SEO friendly URL you would need another Rewrite rule. Have your .htaccess code like this:
Options +FollowSymLinks -MultiViews
# Turn mod_rewrite on
RewriteEngine On
RewriteBase /
RewriteRule ^page/([^/\.]+) search.php?q=$1 [L,QSA,NC]
RewriteCond %{THE_REQUEST} ^[A-Z]{3,}\s/+search\.php\?q=([^\s]+) [NC]
RewriteRule ^ page/%1? [R=302,L]
Once you have verified that it's working fine change R=302 to R=301.
You'd need a [R=301] on the rewrite rule to turn it into a client-side redirect. Otherwise it's purely an internal rewrite and the client will never see the url getting changed.
e.g.
RewriteRule ^page/([^/\.]+)$ search.php?q=$1 [R=301,L]
