https://developer.wordpress.org/reference/functions/wp_get_nav_menu_items/
In functions.php add the following code
function register_my_menu() {
register_nav_menu('my-new-menu',__( 'My New Menu' ));
}
add_action( 'init', 'register_my_menu' );
I after adding this code the new menu will started showing in admin (Appearance->menu)
We can register multiple menus at same time
register_nav_menus(
array(
'mnu-1' => 'Menu One',
'mnu-2' => 'Menu Two',
)
);
Call ‘ wp_nav_menu()’ wherever you want to display the newly created menu
I am just adding in footer.php
<div id="footer-2">
<?php wp_nav_menu( array( 'theme_location' => 'my-new-menu' ) ); ?>
</div>
ref: https://codex.wordpress.org/Function_Reference/register_nav_menu
ref : https://codex.wordpress.org/Function_Reference/register_nav_menus
Example 1
//Api full url : http://localhost/wordpress/wp-json/api/v1/getstuff
add_action( 'rest_api_init', function () {
register_rest_route( 'api', '/v1/getstuff', array(
'methods' => 'GET',
'callback' => 'myFunctionToGetStuff',
));
});
function myFunctionToGetStuff( $request ) {
return 'hello world' ;
}
Example 2 – Passing parameter
//Api url http://localhost/wordpress/wp-json/api/v1/get/author/{number}
add_action( 'rest_api_init', function () {
register_rest_route( 'api', '/v1/get/author/(?P<id>\d+)', array(
'methods' => 'GET',
'callback' => 'myFunctionToGetStuff',
));
});
function myFunctionToGetStuff( $request ) {
return $request['id'] ;
}
Example 3 – Passing multiple parameters
//url : http://localhost/wordpress/wp-json/api/v1/get/{parameter 1}/{parameter2}
add_action( 'rest_api_init', function () {
register_rest_route( 'api', '/v1/get/(?P<param1>[a-z0-9\-]+)/(?P<param2>[a-z0-9\-]+)', array(
'methods' => 'GET',
'callback' => 'myFunctionToGetStuff',
));
});
function myFunctionToGetStuff( $request ) {
return $request['param1']." ".$request['param2'];
}
Example 3- permission check
add_action( 'rest_api_init', function () {
register_rest_route( 'api', '/v1/get/sitemap', array(
'methods' => 'GET',
'callback' => 'api_function_to_get_sitemap',
'permission_callback' => function () {
return permissions_check();
}
));
register_rest_route( 'api', '/v1/get/page/(?P<page_slug>[a-z0-9\-]+)', array(
'methods' => 'GET',
'callback' => 'api_function_to_get_page_by_slug',
'permission_callback' => array( $this, 'permissions_check' )
));
});
function permissions_check(){
//permission check will perform here
return true;
}
$request in call back method is an object of ‘WP_REST_Request’ class this class contains methods like
get_header($key)
get_headers()
get_method()
etc.
we can call these methods with the help of $request object eg:- $request->get_headers()
Ref: https://developer.wordpress.org/reference/functions/register_rest_route/
keep the template file inside your /wp-content/themes/{your theme folder}/
<?php /* Template Name: min Custom Page */ ?>
<?php
get_header();
get_sidebar();
?>
<div id="container">
<?php while ( have_posts() ) : the_post() ?>
<h1 class="postitle"><?php the_title(); ?><hr /></h1>
<div class="content"><?php the_content(); ?></div>
<?php endwhile ?>
</div>
<?php get_footer(); ?>
Here the commented part is very important “/* Template Name: min Custom Page */”
this Template name will be displayed in template selection dropdown
Little bit advanced version. Here I have added Author details, date, edit link, Category, comments, next and previous post links
<?php
/*
* Template Name: Custom Page
* Description: Page template description
*/ ?>
<?php
get_header();
get_sidebar();
?>
<div id="container">
<?php while ( have_posts() ) : the_post() ?>
<h1 class="postitle"><?php the_title(); ?><hr /></h1>
<div class="content"><?php the_content(); ?></div>
<div class="postinfo">
Author: <span class="author"><?php the_author(); ?></span> on <span class="date"><?php the_date(); ?></span>
<span class="edit"><?php edit_post_link(__('edit?')); ?></span> <br>
Category: <span class="cat"> <?php the_category(', ') ; ?></span><br>
<span class="tags"><?php the_tags(); ?></span>
</div>
<?php wp_link_pages(array('before' => '<p><strong>Pages:</strong> ', 'after' => '</p>', 'next_or_number' => 'number')); ?>
<div class="navigation">
<div class="alignleft"><?php next_post_link('Newer: %link') ?></div>
<div class="alignright"><?php previous_post_link('Older: %link') ?></div>
</div>
<div class="comments">
<?php if (comments_open()) comments_template(); ?>
</div>
<?php endwhile ?>
</div>
<?php get_footer(); ?>
