wordpress and custom htaccess rules - php

I am looking over my code for 3 hours and I don't get it. I hope that you can help me.
I have a wordpress blog with Custom Post Types and Advanced Custom Fields installed. Its working pretty nice. I use a basic filter function over the custom fields as described here: http://www.advancedcustomfields.com/resources/creating-wp-archive-custom-field-filter/
To filter the custom fields I use the get-parameters form the url. So the url comes in the form like:
www.domain.tld/?post_type=movie&land=usa&typ=love&actor=kidman
Now I would like the have a pretty url in the form:
www.domain.tld/movie/usa/love/kidman
And hier comes the issue, I cant get the .htaccess right :(
My Code is:
AddHandler php56-cgi .php
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^movie/(.*)/(.*)/(.*)$ /?post_type=movie&land=$1&typ=$2&actor=$3 [L]
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
It's not working. The result is a 404. I believe is's a "wordpress-thing" that I don't get.
If I change the code to:
RewriteRule ^movie/(.*)/(.*)/(.*)$ http://www.domain.tld/?post_type=movie&land=$1&typ=$2&actor=$3 [L]
It works as a normal redirect.
If I change it to
RewriteRule ^movie/(.*)/(.*)/(.*)$ file.php/?post_type=movie&land=$1&typ=$2&actor=$3 [L]
where file.php is a non wordpress file, it works as well (It shows the content of file.php)
It seems that I'am not able to "call" a wordpress-specific file like index.php.
I hope you can help me, and thanks that you read through my non native english ;)

I solved my problem on my own :)
As always, the solution is pretty simple if know where to look.
I had a deep look into: http://codex.wordpress.org/Rewrite_API/add_rewrite_rule and http://codex.wordpress.org/Rewrite_API/add_rewrite_tag
Finally the coin dropped.
First I deleted every custom code I made in the .htaccess cause its not the location to solve my problem.
I added the following to my functions.php
function custom_rewrite_basic() {
add_rewrite_rule('^movie/(.*)/(.*)/(.*)?', 'index.php?post_type=movie&land=$matches[1]&typ=$matches[2]&actor=$matches[3]', 'top');
}
add_action('init', 'custom_rewrite_basic');
function custom_rewrite_tag() {
add_rewrite_tag('%land%', '([^&]+)');
add_rewrite_tag('%typ%', '([^&]+)');
add_rewrite_tag('%actor%', '([^&]+)');
}
add_action('init', 'custom_rewrite_tag', 10, 0);
After you edited your function.php don't forget to save the permalinks in your wordpress settings.
Now I have access to the "query_vars" in the template:
$wp_query->query_vars['land']
or the functions.php:
$query->query_vars[ land ]
It works perfect :)
Thank u anyway and have a nice weekend

Hide get parameters names from the URL

I know this can be done using Rewrite engine but I am unable to do this
This is my .htaccess file
# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
# END WordPress
I have this url www.mysite.com/report?page=my-report-name
Now what I want to acheive is this : www.mysite.com/report/my-report-name
The file where I am accessing this get variable name page is reports.php and its not in my root directory
Path to my file is : root/themes/fount/intel/reports.php
Can anyone help?
Try this code,
<IfModule mod_rewrite.c>
Options +FollowSymlinks
RewriteEngine on
RewriteBase /
# /anything/anything -> anything.php?url=anything
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^([A-Za-z0-9_])/([^/]*)$ /$1.php?url=$2 [L]
</IfModule>
If the page.php filename will always be the same, then do it like this:
<IfModule mod_rewrite.c>
Options +FollowSymlinks
RewriteEngine on
RewriteBase /
# /page/anything -> page.php?url=anything
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^page/([^/]*)$ /page.php?url=$1 [L]
</IfModule>
Thanks!
Updated answer
To add a routing which points to an external handler PHP file, the following snippet should be used:
function wprre_add_rewrite_rules() {
global $wp_rewrite;
// pattern with regexps
$wp_rewrite->add_external_rule( '^wp_report/([\w\d-]+)/?', PATH_TO_THE_EXTERNAL_HANDLER.'report.php?report_name=$1' );
}
add_action('init', 'wprre_add_rewrite_rules');
You can spot one difference in the parameter handling between add_external_rule() and the add_rewrite_rule. You must use the match selector as the Apache uses it in this case.
This snippet must placed in a file which is always loaded by your plugin or theme. If you write a plugin it can be the main plugin file. In case of theme development it can be the main functions.php file.
The custom GET parameter registration is working as it was mentioned in the Original answer.
IMPORTANT
After you edited the rewrite rules via code (external or internal both) you must go to the Permalink settings page in the admin panel and click to the Save button without any changes. This is necessary, because this will flush the rewrite rules and the WP will write into the .htaccess file the rules.
This is the reason why I recommend you to hook on the plugin activation event and register the rewrite rules then and immediately run a flush_rewrite_rules() command.
NOTES
The problem with the original answer was that, the add_rewrite_rule() function only works if you route to the default basic index.php. You can only modify the parameters, but you can not route to an external file.
Original answer
I think you should use the WordPress API to achieve this. You will need to add a rewrite rule and tag in you theme or plugin with this syntax:
!! Disclaimer this is only working to route to the basic index.php !!
For the routing, add a rewrite rule which points to your PHP file.
function custom_rewrite_basic() {
add_rewrite_rule('^report/([\w-]+)/?', 'index.php?page=$matches[1]', 'top');
}
add_action('init', 'custom_rewrite_basic');
If you want to use a query parameter which is not in the standard WP parameter list, you need to add that custom parameter name.
function custom_rewrite_tag() {
add_rewrite_tag('%page%', '([^&]+)');
}
add_action('init', 'custom_rewrite_tag', 10, 0);
Be aware to you use built in parameters if you do not use as the WP API.
In this Codex article you find more details about the topic:
https://codex.wordpress.org/Rewrite_API/add_rewrite_rule
For troubleshooting and deeper dive understanding you might to check this Codex article too, which describes the proper rewrite rule usage. Because some in circumstances you need to reset the rewrite rules (plugin activation / deactivation).
https://codex.wordpress.org/Function_Reference/flush_rewrite_rules
Finally this solution worked for me
I have added this in my functions.php file that is in our theme folder
function rewrite_photo_url(){
add_rewrite_rule('^report/([^/]*)/?','index.php?page_id=2671&value=$matches[1]','top');
}
function register_custom_query_vars($query_vars){
$query_vars[] = 'value';
return $query_vars;
}
add_action('init','rewrite_photo_url');
add_filter('query_vars','register_custom_query_vars');
and then in my php file I use get_query_var('vale') to get my parameter value

How to convert get strings to slug?

Bounty Note: I've found my solution for my question using add_rewrite_rules. I will reward the bounty to anyone who can provide me with the same solution in apache RewriteRules format.
I've read How can I create friendly URLs with .htaccess? but it still difficult and complicate to me.
I am running WordPress Multisite, and I have a sub domain website cp.example.com and I'm writing a php app on this sub domain.
I have a website address that is looks like this:
http://cp.example.com/sales.php?id=12345&userid=123456&uid=83hkuhdqhuhd873xsuhdqwiuhdiq
Is it possible for me to let user access the website via:
http://cp.example.com/sales/12345/userid/123456/83hkuhdqhuhd873xsuhdqwiuhdiq
And if I were to do that will php still be able to do $_GET on the values?
e.g $_GET['id'], $_GET['userid'] and $_GET['uid']?
I'm using WordPress for my base, but i'm writing the app end, using a different table.
I'm trying to avoid using custom post type just to achieve the above.
I've tried the following.
Create a template file view_sales.php in view_sales.php I will require $_GET['id'], $_GET['userid'] and $_GET['uid'] in order to retrieve info from mysql.
in view_sales.php I've also used a different header file and have get_header('sales');
in header-sales.php I've added the following code gotten from the above stack overflow page.
$path_components = explode('/', $_GET['url']);
$id=$path_components[0];
$userid=$path_components[1];
$uid=$path_components[2];
I created a new wp page with slug sales so now the website is
http://cp.example.com/sales/?id=123456&userid=123456&token=98917397219372iheu1i
I only have one .htacess website in my /public_html/example.com domain since it's a multisite so I added the code suggested above to my .htaccess and now it looks like this.
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
# add a trailing slash to /wp-admin
RewriteRule ^([_0-9a-zA-Z-]+/)?wp-admin$ $1wp-admin/ [R=301,L]
RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^ - [L]
RewriteRule ^([_0-9a-zA-Z-]+/)?(wp-(content|admin|includes).*) $2 [L]
RewriteRule ^([_0-9a-zA-Z-]+/)?(.*\.php)$ $2 [L]
RewriteRule . index.php [L]
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*)$ index.php?url=$1 [QSA,L]
</IfModule>
Nothing is working at the moment, still redirecting to the ugly url.
Edited:
I've tried the following
RewriteCond %{HTTP_HOST} !^cp\.example\.com [NC]
RewriteRule ^listing/([a-z0-9]+)$ listing/?action=$1 [L,NC]
RewriteRule ^view/([a-z9-9]+)$ view/?id=$ [L,NC]
I tried different variants of all the above but nothing works.
Edited for add_rewrite_rule method which i tried
function pa_custom_rules() {
add_rewrite_rule('^/listing/([^/]+)/$', 'index.php?pagename=listing&action=$matches[1]', 'top');
}
add_action('init', 'pa_custom_rules');
Printed the rewrite array and I can see the new rule
[^/listing/([^/]+)/$] => index.php?pagename=listing&action=$matches[1]
Visiting index.php works but going to /listing/test/ fails. It returns 404 error.
Finally solved problem which bothered me for last few days.
It appears Rewrite rules for specific domains does not work.
If you wish to change
http://subdomain.example.com/listing?action=add(e.g. or DEL or VIEW)
of a Wordpress MULTISITE to
http://subdomain.example.com/add/ (e.g.or DEL or VIEW)
you have to not only add rewrite rules, but it's also compulsory to rewrite/add the tag to query_var.
You need to add the following to function or create a plugin to initiate it once.
function pa_custom_rules() {
add_rewrite_rule('listing/(.*)$', 'index.php?pagename=listing&action=$matches[1]', 'top');
add_rewrite_tag('%action%', '(.*)');
}
add_action('init', 'pa_custom_rules');
once done you will be able to access http://subdomain.example.com/listing/add
In your page (in this case, my page name is 'listing'), you will no longer get 404 error and you can get the value of "action" (in this case Add/Del/View) by using
http://subdomain.example.com/listing/**add**
$a = get_query_var('action');
echo $a; //prints **add**
Note: You cannot get the value of action using $_GET like how RewriteRule works, but this should be able to get most things done.
I can keep working on wordpress and get all my customise beautiful links and throw away my last 3 days of work exploring Laravel and Symfony3. Thank God.
I have a website that is like this
http://cp.example.com/sales.php?id=12345&userid=123456&uid=83hkuhdqhuhd873xsuhdqwiuhdiq
Is it possible for me to let user access the website via
http://cp.example.com/sales/12345/userid/123456/83hkuhdqhuhd873xsuhdqwiuhdiq
Yes, its possible, e.g.:
RewriteEngine On
RewriteRule ^sales/(\d+)/userid/(\d+)/([a-z0-8]+)$ sales.php?id=$1&userid=$2&uid=$3 [L,NC]
And if i were to do that.. will php still be able to do $_GET on the
values?
e.g $_GET['id'], $_GET['userid'] and $_GET['uid']
Yes, of course php will be able do that.

Rewriting a query string to different directory in wordpress

I feel like I've tried everything to get this to work, but my currently-limited knowledge of wordpress may be responsible.
I want to modify part of a query string in a url, so
/my_site/wp-admin/admin.php?page=events
will redirect to:
/my_site/wp-admin/admin.php?page=espresso_events
These urls are hard-coded within the plugin, but I want to be able to define my own query string that will point to the url, adding any additional query parameters onto the end.
function plugin_activate()
{
global $wp_rewrite;
$wp_rewrite->flush_rules();
}
function remove_espresso_url()
{
add_rewrite_rule('page=events&(.*)$',
'wp-admin/admin.php?page=espresso_events&$matches[1]',
'top'
);
}
register_activation_hook(__FILE__, 'plugin_activate');
add_action('init', 'remove_espresso_url');
The rule is appearing in $wp_rewrite->non_wp_rules. I've tried various rule variations, and even entirely different rules, but nothing works. I've checked my local server settings and url rewriting is enabled, and my .htaccess file is fine as well.
I've also installed the Monkeyman Rewrite Analyzer plugin, and my rewrite rules aren't appearing in there at all.
Here's the resulting value from wp_rewrite->mod_rewrite_rules()
RewriteEngine On
RewriteBase /event_espresso/
RewriteRule ^index\.php$ - [L]
RewriteRule ^page=events&(.*)$ /event_espresso/wp-admin/admin.php?page=espresso_events&$matches[1] [QSA,L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /event_espresso/index.php [L]
Edit: This appears to be because I'm trying to rewrite the query string, however what I need to do is use RewriteCond %{QUERY_STRING}, but I'm not sure Wordpress allows me to add new rewrite conditions.
I finally resolved the problem.
For the sake of brevity, I'll just link to my new question, where I've posted the answer; Custom .htaccess rewrite rules in wordpress not executing

Wordpress add rewrite rule to point to plugin file

Firstly, I have tried several different suggestions from other stackoverflow users but I haven't had any luck.
I'm trying to build a kind of api from inside a plugin. The task is to let an external system call a URL within my plugin in order for it to initiate an internal procedure.
Currently I have a class which has a contructor. This is inside that constructor.
add_action( 'init', 'my_rewrite' );
function my_rewrite() {
global $wp_rewrite;
$plugin_url = plugins_url( 'my-api.php', __FILE__ );
$plugin_url = substr( $plugin_url, strlen( home_url() ) + 1 );
add_rewrite_rule('/my-api/(.*)', $plugin_url ,'top');
$wp_rewrite->flush_rules(true);
}
This then generates a RewriteRule in my htaccess file.
RewriteRule ^/my-api/(.*) /wp-content/plugins/my-api/classes/my-api.php [QSA,L]
Below is the whole .htaccess file for context
# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteRule ^/slurp-api/(.*) /wp-content/plugins/slurp/classes/my-api.php [QSA,L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
# END WordPress
For whatever reason when I visit site.dev/my-api I see a 404 page rather than the echo statement that should run from my-api.php
The dev site is being run through mamp pro if that is any help.
Any pointers as to why this rewrite isn't playing fair would be greatly appreciated.
Thanks
Remove the leading forward slash from the original request
RewriteRule ^my-api/(.*) /wp-content/plugins/my-api/classes/my-api.php [QSA,L]
And make sure the file my-api.php exists at the location you give in the rewrite target:
/wp-content/plugins/my-api/classes/my-api.php
So as not to intentionally give it a non-existent target.
As #Starkeen mentions in the comments, you can remove the leading forward slash from the target also, like this
RewriteRule ^my-api/(.*) wp-content/plugins/my-api/classes/my-api.php [QSA,L]
So, after much tinkering I came upon the correct answer.
I changed this line to
add_rewrite_rule('my-api', $plugin_url ,'top');
I tried many variations on this but this one finally worked. Thanks for the help.

URL $_GET will not work

I have a problem I never had and I can't find the reason.
I moved my site to another host and now it doesnt "read" the $_GET variables.
I have this url: http://whatever.com/path?filtro=si&provincia=Santa+Fe&localidad=Rosario
And if I call this:
$localidad = $_GET['localidad'];
$provincia = $_GET['provincia'];
$filtro = $_GET['filtro'];
echo $localidad;
echo "hola";
echo $provincia;
echo $filtro;
Nothing prints except "hola", so there is no PHP error.
Here's my .htaccess:
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
Im working on a Wordpres site, perhaps it has something to do with Permalinks or something, Im really lost. Thank you very much, I appreciate your help.
EDIT
I renamed my .htacces so it wont read it and the page broke, so I went to permalink settings in wordpress and set them to
- Post Name http://luminias.com/index.php/example-page/
And now IT WORKS, but, now this is thw url:
http://whatever.com/index.php/path/?filtro=si&provincia=Santa+Fe&localidad=Rosario
And it prints all the $_GET, but I need that "/index.php/" gone..
Add add_rewrite_tag function in your function.php for all parameter :
function custom_rewrite_tag() {
add_rewrite_tag('%localidad%', '([^&]+)');
}
add_action('init', 'custom_rewrite_tag', 10, 0);
And you can call your parameter in template using
$wp_query->query_vars['localidad']
Here is the full documentation
Note that using $_GET on a rewritten URL will not work, even if the
rewrite includes the querystring variables. You must use $wp_query.
