url rewritten: https://exmaple.com/club-contact/MzYzOU1ZX1NFQ1JFVF9TVFVGRg==/officer
function custom_rewrite( $wp_rewrite ) {
$feed_rules = array(
'club-contact/(.+)' => 'index.php?page_id=3692&officer=' . $wp_rewrite->preg_index(1),
);
$wp_rewrite->rules = $feed_rules + $wp_rewrite->rules;
}
function custom_wp_querystring() {
add_rewrite_tag('%officer%','([^&]+)');
}
add_action( 'init', 'custom_wp_querystring');
add_filter( 'generate_rewrite_rules', 'custom_rewrite' );

add_rewrite_rule - suddenly stopped working (wordpress)

I have a url
example.com/sample-page/?amount=567
It initially worked ok, it redirects to:
example.com/sample-page/567
But after few days, i noticed its not working any more.
Its now redirecting to post without query var or get var
What could be the reason?? Is there any solution??
I used below codes in my functions.php file:
& I already flushed permalinks.
I am using custom post type
I have removed custom post type base from url using a plugin.
UPDATE
I just noticed Its due to empty post id/pagename.
So now, Question is how to get page name of current post...inside init function dynamically??
//https://developer.wordpress.org/reference/functions/wp_redirect/#comment-4109
add_action( 'init', function() {
global $wp;
$pagename = $wp->request;
add_rewrite_rule( ''.$pagename.'/([0-9]+)[/]?$', 'index.php?pagename='.$pagename.'&amount=$matches[1]', 'top' );
} );
add_filter( 'query_vars', function( $query_vars ) {
$query_vars[] = 'amount';
return $query_vars;
} );
function wpb_change_search_url() {
global $wp;
if ( ! empty( $_GET['amount'] ) ) {
wp_redirect( get_permalink( home_url( $wp->request ) ) . urlencode( get_query_var( 'amount' ) ) );
exit();
}
}
add_action( 'template_redirect', 'wpb_change_search_url' );

Wordpress plugin to create virtual page using rewrite rules

I'm creating a plugin that will need virtual pages to output content on the front end.
Here is my code:
add_filter( 'generate_rewrite_rules', function ( $wp_rewrite ) {
$wp_rewrite->rules = array_merge(
['my-custom-url/?$' => 'index.php?custom=1'],
$wp_rewrite->rules
);
} );
add_filter( 'query_vars', function( $query_vars ) {
$query_vars[] = 'custom';
return $query_vars;
} );
add_action( 'template_redirect', function() {
$custom = intval( get_query_var( 'custom' ) );
if ( $custom ) {
include plugin_dir_path( __FILE__ ) . 'templates/states.php';
exit();
}
} );
In the plugin I have templates/states.php and in that file I have:
<?php
$state = get_query_var( 'custom' );
echo $state;
?>
When I visit localhost/my-custom-url/somevariable I get a page not found from Wordpress. I've tried flushing my permalinks.
As I said in the comments
I have never used generate_rewrite_rule
The documentation on it is pretty weak too. But this key looks just like I would expect a Regular expresion to be. And, that makes sense as that is how real Mod Rewrite and Htaccess work.
add_filter( 'generate_rewrite_rules', function ( $wp_rewrite ) {
$wp_rewrite->rules = array_merge(
['my-custom-url/?$' => 'index.php?custom=1'],
$wp_rewrite->rules
);
} );
So this $ here matches the end of the string, this means your URL must end with my-custom-url with an optional / because of the ?.
When I visit localhost/my-custom-url/somevariable I get a page not found
That's not surprising as your URL does not end in a way that will match that pattern.
Test it yourself!
So you can just remove the $ you may or may not want to keep the / optional.
add_filter( 'generate_rewrite_rules', function ( $wp_rewrite ) {
$wp_rewrite->rules = array_merge(
['my-custom-url/?' => 'index.php?custom=1'],
$wp_rewrite->rules
);
} );
One note is this will make that match anywhere in the URL
Test this one
Hope it works.

Rewrite customly generated urls in wordpress

I'm using Wordpress, where I have used my custom designed template, so I'm using custom generated URL's in most cases.
I want my URL to look like: website_url/details/191/
I want to rewrite this to more SEO friendly. I don't know how to write rewrite rules in htaccess and could use your help.
add_filter( 'rewrite_rules_array','my_insert_rewrite_rules' );
add_filter( 'query_vars','my_insert_query_vars' );
add_action( 'wp_loaded','my_flush_rules' );
// flush_rules() if our rules are not yet included
function my_flush_rules(){
$rules = get_option( 'rewrite_rules' );
if ( ! isset( $rules['(details)/(\d*)$'] ) ) {
global $wp_rewrite;
$wp_rewrite->flush_rules();
}
}
// Adding a new rule
function my_insert_rewrite_rules( $rules )
{
$newrules = array();
$newrules['(details)/(\d*)$'] = 'index.php? pagename=$matches[1]&id=$matches[2]';
return $newrules + $rules;
}
// Adding the id var so that WP recognizes it
function my_insert_query_vars( $vars )
{
array_push($vars, 'id');
return $vars;
}
This is what I have added in my function.php but no change.

Stuck with custom URL REWRITE

I'm creating a custom url rewrite structure for my WordPress site.
First I had the following code to have url: /objekt/<GID> which loads objekt page and have query var GID.
add_action( 'init', 'objekt_url_rewrites_init' );
function objekt_url_rewrites_init(){
add_rewrite_rule(
'objekt/([A-Za-z_0-9]+)/?$',
'index.php?pagename=objekt&GID=$matches[0]',
'top' );
}
add_filter( 'query_vars', 'objekt_url_query_vars' );
function objekt_url_query_vars( $query_vars ){
$query_vars[] = 'GID';
return $query_vars;
}
Now, I need to change URL structure to /en/objekt/<GID>. So, I change
objekt/([A-Za-z_0-9]+)/?$
to
en/objekt/([A-Za-z_0-9]+)/?$
But its not working!
When I visit /en/objekt/<GID> it just redirects to /en/objekt/ and not getting any query var named 'GID'

WordPress Rewrite Plugin

Example Code:
function flush_rewrite_rules()
{
global $wp_rewrite;
$wp_rewrite->flush_rules();
}
function activate()
{
global $wp_rewrite;
createRewriteRules( $wp_rewrite );
flush_rewrite_rules();
}
function createRewriteRules( $rewrite )
{
global $wp_rewrite;
$new_rules = array( 'option/(.+)' => 'index.php?option=' . $wp_rewrite->preg_index(1) );
$wp_rewrite->rules = $new_rules + $wp_rewrite->rules; // ERROR HERE............
return $wp_rewrite;
}
add_action( 'generate_rewrite_rules', createRewriteRules );
register_activation_hook( file, activate );
Sometimes gives Fatal error: Unsupported operand types, but activates the plugin and doesn't stop it from working... What am I doing wrong here?
Probably either $new_rules or $wp_rewrite->rules is not an array at the moment you want to combine them.
You could add a test to see if they are arrays, and if not, initialize them as an empty array.
(Addition:
Why pass $rewrite as an argument, when you use a global to get the original variable?)
