get_next_posts_link() and get_previous_posts_link() are for linking between pages of a paginated post archive.
For navigation between individual posts you want get_next_post_link() and get_previous_post_link(). Note the singular "post".
function myslug_render_post_navigation(){
echo get_next_post_link( __( 'Previous post' ) ) . ' | ' . ...

I've managed to print the error message by adding the following to the functions.php:
function exception_handler($exception) {
echo "Uncaught exception: " , $exception->getMessage(), "\n";
}
set_exception_handler('exception_handler');
For some reason logs did not include the error details before.
The error is call to undefined ...

Your code is fine to me, except you made a mistake here:
template_redirect('/product/channel-mcgilchrist');
WordPress does not have a function named template_redirect, only a hook with that name.
So you should have used either wp_redirect() or wp_safe_redirect() which are valid functions to perform URL/page redirections in WordPress.
wp_safe_redirect( '/...

You can check the current user role in the same action and apply "display none" for that specific user role
$user = wp_get_current_user();
if ( in_array( 'author', (array) $user->roles ) ) {
//The user has the "author" role
}

You have to think into the opposite direction: Don't pull the variables from the template, push them into it. Templates should be as simple as possible, the shouldn't know anything about the content of the rest of your code, for example function names.
In other words: use hooks.
In your template:
// the numbers are just context examples
do_action( 'something'...

You can't replace the function, but you can substitute it:
Copy the function to your child theme's functions file.
Rename the function.
Modify it as needed.
Find the template file that references it, such as header.php, and copy that to your child theme.
In your child theme's new template file replace the reference to the original function with your renamed ...

You need to get the term object first.
//Your meta field
$post_custom_title = get_post_meta($post_id,'car_name',true);
//Get the term object by id. change taxonomy_slug to the taxonomy you intend to use
$term = get_term_by( 'id', $post_custom_title, 'taxonomy_slug' );

$term_name = $term->name;

Hey so it is possible to do this, I wrote an article about it. You need to do it on the javascript side using the Gutenberg's data module api.
Here's the code that'll get this up and running for you.

Within the wp_get_document_title() function we have:
// If it's a search, use a dynamic search results title.
} elseif ( is_search() ) {
/* translators: %s: search phrase */
$title['title'] = sprintf(
__( 'Search Results for “%s”' ),
get_search_query()
);
so you could hook into the ...

From what we have to go on, it sounds as though your locations will become WooCommerce product categories (or tags). You can also create new categories if you're already using WooCommerce's default category.

You absolutely did not understand how the code from my previous answer works, yeah? The PHP ternary operator $result = $a ? $b : $c works the same way as the following construction:
if ( $a ) {
$result = $b;
} else {
$result = $c;
}
So the whole idea was to check if the get_user_meta(get_current_user_id(), 'last_name', true) function returns an ...

The first thing that i am not getting is $exclusive->y ? can you please share custom field settings that you have created?
And the second thing that i have found, you must have to put global $post; in the first line of the function :

function wpb_new_title( $title, $id ) {
global $post;

Use PHP ternary comparsion operator to check if get_user_meta() function returns blank or non-blank result:
function colaborador_nome($atts) {
if (is_user_logged_in() && !is_feed()) {
return ' '. (get_user_meta( get_current_user_id(), 'first_name', true ) ?: "Hi >No Name<, please settle your name in your account.")...

The issue here is that both the functions have the same name - colaborator_avatar().
Make sure that $new_user contains the current user. Else use get_current_user_id() like this:
get_user_meta( get_current_user_id(), 'first_name', true );
Show avatar and first name:
// show user avatar if logged in
function colaborator_avatar($atts)
{

I searched for 'wordpress get name of logged in user' and the first result gave wp_get_current_user, which will show logged in user first name. Examples of how to use from that page:

I fixed the issue myself by editing a line in functions.php and it no longer shows the error message for me. The error was:

The code exactly as you put it in your question works fine for me and does exactly what you suggested.
To make it work I had to make sure my WP post editor was in code editor mode as HTML or Visual Editor may create extra problems:

Not sure what you would need this for but this is how you take the data of the variable $result from the operation function to your shortcode:
operation();
function operation(){
$result=5+1;
return $result;
}
function my_function(){
$result = operation();
return (string)$result;
}
add_shortcode( 'my-shortcode', 'my_function' );

You can do this like bellow
// register shortcode

Do not use "about" as handle as it seems to be not unique and used by WordPress itself. I don't see the list of style handles is documented somewhere. Anyway, use something unique like 'rejaur-about':

if ( is_front_page() ) {
// enqueue front page styles

I don't really understand what you're trying to do. Why don't you just call the function inside the shortcode handler? This looks more like general PHP question.
Say we have a variable in our functions.php or wherever you define your shortcodes:
$another_var = doSomeFunctionThatReturnsData();
With modern anonymous functions, you can pass variables using the ...

This will depend on how your theme is structuring the templates for single.php (individual post view) but I'll show you what to look for and how to apply via CSS.

This may be a terrible way to go about population of a CF7 field... However, the way I have done so in the past is to use an identifier as the default value of the field you want to populate, for example {{cf7_year}}.
I would then use a mixture of PHP to query and get the values (if required), and format that result into a string that can in-turn be used in ...

I dont understand where are you calling from. I can give you an alternative solution that may or may not work in your case (since I don't fully understand your case):
This is your ajax-url on your site:

Usually we attach it to the JS to run AJAX calls:
wp_localize_script( 'THE_JS_THAT WAS_ENQUEUED', 'PARAMS', array( '...

That's not how filters work. Much like a filter in real life, something goes in, it gets changed, and the result goes out. Filters always take in a parameter and return something. They're an opportunity to change something
So if we take this:
$review_num_fetch = apply_filters('tourmaster_review_num_fetch', 5);
This means the plugin uses 5, but it has given ...

As of WordPress 5.4 _doing_it_wrong() is no longer marked private, so it looks like we can just use it.

Few possibilities here:
In index.php you find the_content() and replace it with:
$content = get_the_content( $more_link_text, $strip_teaser );
$content = apply_filters( 'the_content', $content );
$content = str_replace( ']]>', ']]>', $content );
$replace = array(
'autoplay=""' => ''
);
$text = str_replace(array_keys($replace), $...

In general programming, globals are bad practice:
You can't easily look at the use of a global in one place and see all the other uses, e.g. where it was set or will be read later.
You have many places to change the use of that variable if e.g. the use or format of it changes.
This makes it hard to make reliable changes to your code and to debug where/who ...

Well if u already use your variable in the global scope, you should also define it in the global scope, not inside the function.
You can then simply include the php file where u define ur global variable (lets call it source script) into the script u wanna use, with a simple include or require statement before using it. I precisely work like this too in my ...

It looks like wp_list_categories($args) will output directly when you call it, which is why the output comes out in a weird place. and ideally what you need is to capture the output and return it, but luckily wp_list_categories allows you to do this with the 'echo' parameter. Try:
$args['echo'] = FALSE;
return wp_list_categories($args);

Yes, this absolutely is possible. There are a couple of steps that you would need to take to get this working;
Check that the user is currently on the front page, you can use the is_front_page function for this, you may need to use is_home or even both depending on your configuration and requirements.
Check that the user is currently logged in, you can use ...

What do you consider to be the home page?
Do you want to change what is answering on the / url on your website?
If so, I think that you can use the init hook and use wp_redirect() function to send your user wherever you want based on the result of wp_get_current_user() result.
Something like that.

if ($user = ...

Three things to check:

No, there's no need to use wp_set_current_user().
I was wondering how to fire wp_head action if single post by certain
users (either by user ID or username)?
You can use $post->post_author to get the ID of the author of the post, and put the user ID list in an array, then just do in_array() to check if the author ID is in the ID list. For example:

There are several problems with your function. For example, $tablename points to a table that does not exist. And you don't need it anyway.

I don't think Wordpress knows to load or run anything from your registerProcess.php file, so what I would do is leave the register_user() function in that file, and then require_once it from functions.php and do the active part of the code - the if .. register_user() inside functions.php where it will be run. (This is probably a bad way to do this, but if it ...

As per my comment, I'm not sure why you'd want to do this, but it is possible.
You would use something like this for your CSS:

}
That's just your stylesheet targeting any class that starts with random-. You could change that to be whatever you want it to be, say entry- or whatever. You'll just need ...
