OK it might sound stange but I am facing a good challenge with wordpress.
when echoing the_permalink(); and checking the portfolio pages, I am getting a link something like this:
http://www.domain.com/?portfolio=test
(Where test is the portfolio name).
Is there any option to return the permalink trimmed to ?portfolio=test keeping out the domain url?
While asking, I think I got the answer already (trim()) but I would like to hear your ideas too.
every answer will be much appreciated!
You can obtain the permalink of a post by doing something like so:
<?php
function my_permalink() {
echo substr(get_permalink(), strlen(get_option('home')));
}
?>
The get_option method replaces the deprecated get_settings method, and allows you to retrieve named option values from the database:
http://codex.wordpress.org/Function_Reference/get_option
The 'home' value passed in to the get_option method will return the site URL.

On the WordPress site using Avada, My situation is very much similar to
https://stackoverflow.com/a/40250428/12323081
They have given the code to be added into functions.php, As per my understanding the code should go in the child theme of Avada, but I don't understand where this part of the code will go?
(Which template file should this code be added to?)
Once this is done, you can query for these variables in your template:
if ( get_query_var('firstName') ) {
echo get_query_var('firstName');
}
if ( get_query_var('lastName') ) {
echo get_query_var('lastName');
}
Once added, how can these parameters be called on Front End?
Any help will be highly appreciated.
After doing quite some R&D, there seems to be a very simple solution to get parameters from the URL in WP/Avada.
In order to achieve the result in my question, please use the Title element and then make use of the dynamic field 'Request Parameter' -> Param Type - Get -> Query Var - firstName

I don't know the exact meaning of the question but someone asked me this question in interview. I just want to know that there's something like that, we use any route algorithm in Wordpress?
This could be a trick question because routing would mean mapping an HTTP request to trigger specific function or method that would handle the request which is not something that WordPress does (there is a section about WordPress at the bottom). In simple word, you read the HTTP request information to decide what function is going to be triggered.
Bit more details in simple words
if you are building a PHP project from scratch and want to display specific content or trigger a method/function there are usually two option (without routing)
Using POST , GET or REQUEST variables and complex conditional statements to achieve what you want, so a result URL could be something like this
http://example.com/index.php?view=pubications&per_page=5
Setting a PHP file for each type of content
http://example.com/publications.php?per_page=5
However, if you created a Router (Routing algorithm as you named it or routing system) then pushed all requests to index.php and have the latter include let's say something like this:
// Include the Router class
require('classes/router.php');
// Include functions responsible for display our content
require('view/display.php');
I'll not go into how to build a router, just giving examples assuming that you already have one just to give you an idea how routing works.
So assuming you have a router and function to display a contact form for example, you'd also include something like this:
Router::add('/contact-us', get_contact_form(),'get');
Router::add('/contact-us', handle_contact_form(),'post');
Then initialize the Router
Router::initialize('/');
Again assuming you have a complete Router, the above function would tell the index.php file to handle HTTP requests on this URL differently:
http://example.com/contact-us
If it's the default request type GET, trigger this function get_contact_form(), but if the request type is POST trigger this one handle_contact_form() which will act and display content differently depending on your needs.
That's great because it would be instead of something like
http://example.com/index.php?page=contact-us
index.php content would handle the request differently since there is no router.
// Include functions responsible for display our content
require('view/display.php');
if( isset($_GET['page']) && $_GET['page'] == 'contact-us'){
echo get_contact_form();
}
if( isset($_GET['page']) && $_GET['page'] == 'contact-us' && isset($_POST['contact_submit']) ){
echo handle_contact_form();
}
Imagine how long and ugly this would look like if you have a lot of pages and a complex site.
So back to WordPress
If you have a new installation you'd notice that the URLs looks something like this:
http://example.com/?p=62
http://example.com/?cat=1
http://example.com/?author=3
So it would just take URL parameters then build a WP_Query based on that, if is p then look for posts in database by ID, if cat then look for categories by ID and so on... (that's the simple explanation, there is a lot going on of course in the back-end, but just to give an idea).
You might notice after changing permalink structure that the above examples would now look something like this:
http://example.com/post-slug
http://example.com/author/name
http://example.com/category/uncategorized
This might look like routing, but it isn't, let's go in a bit more details about how this works.
When requesting a (pretty-link) URL on WordPress, first thing that happens is that the .htaccess looks for a folder/file with same name on the server, if it exists it will served, if not, it would send that request to the index.php file which does one thing:
/** Loads the WordPress Environment and Template */
require( dirname( __FILE__ ) . '/wp-blog-header.php' );
loading the wp-blog-header.php file, which will make a small check to make sure the code only run once then the following:
// Load the WordPress library.
require_once( dirname(__FILE__) . '/wp-load.php' );
// Set up the WordPress query.
wp();
// Load the theme template.
require_once( ABSPATH . WPINC . '/template-loader.php' );
Let's not go deeper into these files, what's concerns us the most is what 'wp-load.php' and 'template-loader.php' does
wp-load.php
This one among other things, looks for wp-config, make sure everything is set correctly, then connect to the database, of course after a lot of initialization, setting up constants loading a lot files that handles different parts of WordPress structure. Part of this process is that WordPress tries to match the request URL with a large set of rule called rewrite rules which are set of regular expressions, when a match is found WordPress will translate that URL into a database query using [WP_Query][1] class which is located at wp-includes/class-wp-query.php and this class will save the query results among other things (query type...etc)
template-loader.php
This one handles the display part, it uses some WordPress function that make use of WP_Query (eg:is_home()) to find out what type of content is to be displayed, then loads the the correct template based on that, and finally the template will use WP_Query to show the result.
I need help with this: I need that the url of the downloadable products link with an external url. I´m trying to add a custom field and replace the filters woocommerce_product_file and woocommerce_product_file_download_path but it didn't worked, I think because I can´t call to the product data from the order. Someone did this? Thank you for your help!
The code doesn't works. Now is something like:
*function mostrar_campo_personalizado_en_order($file_id){
global $wpdb, $woocommerce;
echo get_post_meta($file_id, 'downloadable_url', true);
}
add_filter( 'woocommerce_product_file', 'mostrar_campo_personalizado_en_order', 10, 1 );
add_filter( 'woocommerce_product_file_download_path', 'mostrar_campo_personalizado_en_order', 10, 1 );*
I don´t know if I´m working in the correct way, I need to change the url of the downloadable products because woocommerce internally routed. Because I couldn't modify him, I intente removal and display a custom post field. The page is in a test server because the site is on line. The url of the tester server ishttp://lab.jus.raffles.com.ar/my-account/ but you need credential to come in:
user: paula
pass: 5VPeGgAHWzYX1T
As we all know the WordPress' feed url is www.mysite.com/feed.
I have edited the feed-rss2.php file to show thumbnails if a certain GET parameter is passed. See the code below:
<?php if($_GET['c'] == 'detailswiththumb') echo the_post_thumbnail( array(100,100) ); ?>
But when I open the feed address like this:
www.mysite.com/feed?c=detailswiththumb
The code doesn't work. Can the arguments be passed this way? Am I missing something? Please help.
Firstly, the function is get_the_post_thumbnail() not the_post_thumbnail().
Then, their is one more problem in your code, that you have to pass the post id to get its thumbnail (for more info see http://codex.wordpress.org/Function_Reference/get_the_post_thumbnail).
So, first you will have to extract the post id from somewhere and then only you would be able to get the thumbnail. But, I think it would be very tough, so try giving up this thought, for it would take you a lot of time and no living being is going to access that path.
There were browser cache issues. Even with Google Chrome's incognito window. Had to test it with passing fake arguments like...
www.mysite.com/feed?c=detailswiththumb&fakearguments=123
...to clear the cache. And the code is fine.
Sorry for wasting your time guys.
I was wondering which is the best approach to get the catgeory ID when listing the posts within a particular category. Normally, the urls look something like this : www.example.com/?cat=4 and it is pretty easy to get the id. However, I really need the urls to be routed like this www.example.com/categories/hotels . wordpress provides an easy way to do the "pretty" routing, however all of the GET paramater information is lost this way. In this case, the $_GET variable is assigned nothing. I need to be able to say $category = $_GET["cat"] or something like that
What is the easiest approach ?
Can you use the Wordpress get_the_category function to grab the ID (from member variable cat_ID) once you're in the template?
See http://codex.wordpress.org/Function_Reference/get_the_category
e.g.
foreach((get_the_category()) as $category) {
$id = $category->cat_ID;
// do something with $id
}
The thing is that the guy might not really want to associate categories with post ids. In this case, there's the global $wp->query_vars array that contains all the data coming from the GET request even when the routing has been "prettified"
What about the category base setting in the backend? "Configuration" > "Permalinks" and there the last paragraph. See here for docs.
