I have a question regarding wp_rewrite, It doesn't display correctly,
I need to make this url
eduedu/wp-content/plugins/workwork/admin/templates/tcpdf/samp/flash.php
to
eduedu/generator
It works when using .htaccess, the problem is, that It doesnt work when place inside the plugin folder, the htaccess must be place in the root folder of wordpress. So I thought of using wp_rewrite.
Here is my code, I added this on the page when in it will redirect to
eduedu/wp-content/plugins/workwork/admin/templates/tcpdf/samp/flash.php
I'm not sure if its correct, any idea?
add_action('generate_rewrite_rules', 'cs_rewrite_rules');
add_filter('init', 'eduFlush');
function cs_rewrite_rules() {
global $wp_rewrite;
$new_non_wp_rules = array(
'^generator/?$' => 'eduedu/wp-content/plugins/workwork/admin/templates/tcpdf/samp/flash.php',
);
$wp_rewrite->non_wp_rules += $new_non_wp_rules;
}
function eduFlush(){
global $wp_rewrite;
$wp_rewrite->flush_rules();
}
Maybe something along these lines would help:
function site_router() {
global $url_array;
$url_array = explode("/",$_SERVER['REQUEST_URI']);
$route = $url_array[1];
$template_dir = 'wp-content/plugins/workwork/admin/templates/tcpdf';
switch($route) {
case 'generator':
load_template($template_dir.'/samp/flash.php');
die();
break;
}
}
add_action( 'send_headers', 'site_router');
It gets the current URL array (domain.com/url_array[1]), then it gets where you want to get the file from.
The switch gets the url, so domain.com/generator, and then loads in the template from the file you call.
You may need to change the url_array[1] to [2] if wordpress is in a sub-folder (domain.com/wp_root)

I am trying to implement a simple add_hook function using PHP but am coming across some trouble with updating the global array I have to store available/set hooks. If I use add_hook from main.php it works fine and I can add as many hooks as needed, but if doing the same thing from an included file, the $hooks var only updates from within the function.
main.php
require dirname(__FILE__) . '/includes/functions.php';
$hooks = array();
function add_hook($hook_name, $function)
{
global $hooks;
$hooks[$hook_name] = $function;
}
add_hook("hook_name", "some_function");
function execute_hook($hook_name)
{
global $hooks;
foreach ($hooks[$hook_name] as $function) {
if (function_exists($function[0])) {
call_user_func($function[0]);
}
}
}
function execute_hooks($hook_name)
{
global $hooks;
print_r($hooks);
if (array_key_exists($hook_name, $hooks)) {
execute_hook($hook_name);
}
}
print_r($hooks);
// Array ( [hook_name] => some_function )
// missing the array added from functions.php
functions.php
add_hook("build_admin_menu", "hd_modify_menu");
If I print_r at the end of the add_hook function, it will print the added hook, but I think the problem is that the "global" $hooks does not seem to update with the add_hook call from functions.php.
Can anyone explain to me why this is happening and what I can do to fix? Much appreciated!
Please check you code
require dirname(__FILE__) . '/includes/functions.php';
// $hooks = array();
The $hook array is reassigned after including functions.php . you need to comment/remove it. as shown above.
Hope this will help you
Suppose I have a clean wordpress install, with a basic custom theme.
In that theme, I have a custom page template which is just an iframe, which is pointed at a webapp on a different domain.
So suppose my wordpress install can be reached at http://example.com, and my page with the iframe template is located at http://example.com/members/.
I now want to add dynamic routes, so that all requests to http://example.com/members/login, or http://example.com/members/event/1 (for example) all go to http://example.com/members/ but pass the second part of the route ('/login', or '/event/1') to the iframe inside.
What would be the best way to accomplish this, without having to hack into Wordpress' internals?
I found this plugin: https://wordpress.org/plugins/wp-on-routes/ but much to my dismay I discovered that when I tried using it it completely overwrites Wordpress' built in routing, which meant I would have to manually re-add each and every URL (as I understand it, I'm not that accomplished in PHP), which is a no go as my client still needs to be able to post without manually editing php files.
Thank you for reading.
You can add routing using the add_rewrite_rule hook like so:
function custom_rewrite_rule() {
add_rewrite_rule('members/([^/]+)/([^/]+)/?$',
'index.php?memberspage=$matches[1]&event_id=$matches[2]',
'top');
}
add_action('init', 'custom_rewrite_rule', 10, 0);
You may need to create several depending on the URLs you rewriting. You can then use the URL parameters in your template to load the appropriate page in your iframe.
I managed to find a solution for my problem, thanks to Fencer04's suggestion. I found this page: https://developer.wordpress.org/reference/functions/add_rewrite_rule/ where I found an example that was close enough to my problem to work.
So in functions.php:
function custom_rewrite_rule(){
$page_id = 318; // replace this ID with the page with the iFrame template
$page_data = get_post($page_id);
if(!is_object($page_data)){
return; // all other pages don't have to support custom deeplinks
}
// catches deeplinks 1 level deep, i.e.: /members/profile
add_rewrite_rule(
$page_data->post_name . '/([^/]+)/?$',
'index.php?pagename=' . $page_data->post_name . '&memberspage=$matches[1]',
'top'
);
// catches deeplinks 2 levels deep, i.e.: /members/profile/edit
add_rewrite_rule(
$page_data->post_name . '/([^/]+)/([^/]+)/?$',
'index.php?pagename=' . $page_data->post_name . '&memberspage=$matches[1]&members_param=$matches[2]',
'top'
);
// catches 3 levels deep, i.e. /members/profile/edit/confirm
add_rewrite_rule(
$page_data->post_name . '/([^/]+)/([^/]+)/([^/]+)/?$',
'index.php?pagename=' . $page_data->post_name . '&memberspage=$matches[1]&members_param=$matches[2]&members_param2=$matches[3]',
'top'
);
}
add_action('init', custom_rewrite_rule);
Next I added filters for the new query_vars:
add_filter('query_vars', function($vars) {
$vars[] = "memberspage";
$vars[] = "members_param";
$vars[] = "members_param2";
return $vars;
});
And then in my template-iframe.php, I can access these parameters like so:
<?php
// get query strings
global $wp_query;
$page = $wp_query->query_vars['memberspage'];
$params = $wp_query->query_vars['members_param'];
$params2 = $wp_query->query_vars['members_param2'];
$membersBaseURL = 'http://members.domain.com/';
$iframeURL = $membersBaseURL;
if(isset($page)){
$iframeURL = $iframeURL . $page . '/';
}
if(isset($params)){
$iframeURL = $iframeURL . $params . '/';
}
if(isset($params2)){
$iframeURL = $iframeURL . $params2 . '/';
}
?>
<iframe id="iframeLeden" src="<?php echo($iframeURL) ?>" frameborder="0"></iframe>
So now if I go to http://www.domain.com/members/login, it'll show me the correct static WP page, with inside an iframe that shows the page http://members.domain.com/login/ .
I'm trying to change the og:url content on specific posts but I am unsure how to implement my changes from the functions.php file.
I have tried doing this using the content I have found on the internet but believe it has been updated since then.
I have updated the class-opengraph.php file in the the wordress-seo plugin folder which works, please find my edits below:
public function url() {
$url = apply_filters('wpseo_opengraph_url',
WPSEO_Frontend::get_instance()->canonical(false));
if (is_string($url) && $url !== '' ) {
if (is_page(32721)) {
$this->og_tag('og:url', esc_url('testing'));
} else {
$this->og_tag( 'og:url', esc_url( $url ) );
}
return true;
}
return false;
}
It's not good to modify the plugin files directly because when you update the plugin, you will lose all your changes to those files.
There are two solutions that I have found to do such thing.
You get the instance of the class WPSEO_Frontend, then update it's options for the og:url.
e.g.
$object = WPSEO_Frontend::get_instance();
$object->options['og_url'] = esc_url( $url );
This can be added before the wp_head()
You can use add_filter to hook a function to the filter action. We use the filter action below.
Filter: 'wpseo_opengraph_url' - Allow changing the OpenGraph URL
e.g.
function update_og_url($url) {
return "http://www.yoursampleurl.com";
}
add_filter('wpseo_opengraph_url', 'update_og_url', 10, 1);

I am searching a solution to add a custom template for plugin on short code. But I am unable to do it successfully.
I have made a template folder in my plugins folder and put a custom template in it. I want to show this template by putting a short code. For this I have written following piece of code.
function wp_parse_login()
{
add_action('template_redirect', 'my_template');
function my_template()
{
include ('template/login.php');
exit;
}
}
add_shortcode('parse_login_page','wp_parse_login');
but it's not working. I have include this file to my main plugin file. I think I am leaving some hooks.
Here an adapted example from WordPress Codex
function wp_parse_login() {
ob_start();
include ('template/login.php');
return ob_get_clean();
}
add_shortcode('parse_login_page','wp_parse_login');
You first set a page template in DB Like:
$table_post_meta = $wpdb->prefix.'postmeta';
$meta_data = array(
'post_id' => $post_id, (Get dynamically post id of a page)
'meta_key' => '_wp_page_template',
'meta_value' => 'template/login.php' (Give the file path)
);
$wpdb->insert($table_post_meta,$meta_data) or die(mysql_error());
The you write in your this code in your template page:
function wp_parse_login() {
ob_start();
include ('template/login.php');
return ob_get_clean();
}
add_shortcode('parse_login_page','wp_parse_login');
Hope you find your solution.
My website having feature requirement of blogging. I have to make blog which would look same like my website appearance.
How to combine CodeIgniter and Wordpress blogging(only) functionality such that it should look like within same website?
I have seen this question: Wordpress template with codeigniter. But didn't got much clue.
Seems like a bit of overkill.
Why not use a Restful service like json_api to retrieve your posts, then copy over the css file(parts)?
You do this you will need to create 2 files and modify 2 existing functions. One function is in CodeIgniter and the other is in Wordpress.
Here are the steps.
1.) Open your configs/hooks.php file and create a pre_controller hook as follows:
$hook['pre_controller'] = array(
'class' => '',
'function' => 'wp_init',
'filename' => 'wordpress_helper.php',
'filepath' => 'helpers'
);
2.) Create a new file in your helpers directory called 'wordpress_helper.php', and add the following code to it:
/**
*
*/
function wp_init(){
$CI =& get_instance();
$do_blog = TRUE; // this can be a function call to determine whether to load CI or WP
/* here we check whether to do the blog and also we make sure this is a
front-end index call so it does not interfere with other CI modules.
*/
if($do_blog
&& ($CI->router->class == "index" && $CI->router->method == "index")
)
{
// these Wordpress variables need to be globalized because this is a function here eh!
global $post, $q_config, $wp;
global $wp_rewrite, $wp_query, $wp_the_query;
global $allowedentitynames;
global $qs_openssl_functions_used; // this one is needed for qtranslate
// this can be used to help run CI code within Wordpress.
define("CIWORDPRESSED", TRUE);
require_once './wp-load.php';
define('WP_USE_THEMES', true);
// Loads the WordPress Environment and Template
require('./wp-blog-header.php');
// were done. No need to load any more CI stuff.
die();
}
}
3.) Open wp-includes/link-template.php and made the following edit:
if ( ! function_exists('site_url'))
{
function site_url( $path = '', $scheme = null ) {
return get_site_url( null, $path, $scheme );
}
}
4.) Copy url_helper.php from the CodeIgniter helper folder to your APPPATH helper folder
and make the following edit:
if ( ! function_exists('site_url'))
{
function site_url($uri = '', $scheme = null)
{
// if we are in wordpress mode, do the wordpress thingy
if(defined('CIWORDPRESSED') && CIWORDPRESSED){
return get_site_url( null, $path, $scheme );
}else{
$CI =& get_instance();
return $CI->config->site_url($uri);
}
}
}
The steps above will allow you to dynamically load either your CI app or your WP site based on some simple filtering. It also gives you access to all CI functionality within WP of that is something you can use.
