I am trying to use ajax for a Load more posts button on a Custom Post Type
In my functions file I have this:
add_action('rest_api_init', 'custom_api_get_news');
function custom_api_get_news(){
register_rest_route( 'news', '/news', array(
'methods' => 'GET',
'callback' => 'custom_api_get_news_callback'
));
}
function custom_api_get_news_callback($request){
$posts_data = array();
$paged = $request->get_param('page');
$paged = (isset($paged) || !(empty($paged))) ? $paged : 1;
$posts = get_posts( array(
'post_type' => 'news',
'status' => 'published',
'posts_per_page' => 6,
'orderby' => 'post_date',
'order' => 'DESC',
'paged' => $paged
));
foreach($posts as $post){
$id = $post->ID;
$post_thumbnail = (has_post_thumbnail($id)) ? get_the_post_thumbnail_url($id) : null;
$post_cat = get_the_category($id);
$posts_data[] = (object)array(
'id' => $id,
'slug' => $post->post_name,
'type' => $post->post_type,
'title' => $post->post_title,
'featured_img_src' => $post_thumbnail,
'category' => $post_cat[0]->cat_name
);
}
return $posts_data;
}
In my js file I have:
$('#loadButton').click(function() {
let pull_page = 1;
let jsonFlag = true;
if(jsonFlag) {
jsonFlag = false;
pull_page++;
$.getJSON("/wp-json/news/all-posts?page=" + pull_page, function(data){
if(data.length){
var items = [];
$.each(data, function(key, val){
const arr = $.map(val, function(el) {
return el
});
const post_url = arr[1];
const post_title = arr[3];
const post_img = arr[4];
const post_cat = arr[5];
const post_class = (class_counter == 2) ? 'post adjust' : 'post';
let item_string = '<div class="news__holder">' + post_img + '</div>';
items.push(item_string);
});
if(data.length >= 6){
$("#news-archive").append(items);
} else {
$("#news-archive").append(items);
$("#load-more").hide();
}
} else {
$("#load-more").hide();
}
}).done(function(data){
if(data.length){
jsonFlag = true;
}
});
}
});
And on the archive page:
<?php
$paged = (get_query_var('paged')) ? get_query_var('paged') : 1;
$args = array(
'post_type' => 'news',
'post_status' => 'publish',
'posts_per_page' => 6,
'order_by' => 'post_date',
'order' => 'DESC',
'paged' => $paged
);
$news = new WP_Query( $args );
if( $news->have_posts() ) :
?>
<section id="news-archive" class="news">
<?php while( $news->have_posts() ): $news->the_post(); ?>
<div class="news__holder">
<?php the_post_thumbnail(); ?>
<p class="news__holder__date"><?php the_date(); ?></p>
<h3><?php the_title(); ?></h4>
<?php the_excerpt(); ?>
<a href="<?php the_permalink(); ?>">Read More</a>
</div>
<?php endwhile; wp_reset_postdata(); ?>
</section>
<?php
if($news->post_count < 6) {
} else {
?>
<section id="load-more" class="load-more">
<div class="load-more__holder">
<button id="loadButton" type="button" name="button">Load More Posts</button>
</div>
</section>
<?php } ?>
<?php endif; ?>
The problem I am having is when I click on the Load More button I am getting an error in the console of GET http://localhost:8888/una/wp-json/news/all-posts?page=2 404 (Not Found)
I am not sure if this matters but I had seen on a few other posts some people having trouble with this part but mine is returning the json fine if you go to http://localhost:8888/una/wp-json/news -- Below is what is shown at this url. Any ideas on how to solve this error?

Reset to default 1The URL you're using is not the URL that you've registered.
This code:
register_rest_route( 'news', '/news', array(
'methods' => 'GET',
'callback' => 'custom_api_get_news_callback'
));
Registers this URL:
http://localhost:8888/una/wp-json/news/news
But you're sending requests to
http://localhost:8888/una/wp-json/news/all-posts
Nowhere in your code have you defined an all-posts endpoint.
You either need to change /news in register_rest_route() to /all-posts, or the /all-posts in your URL to /news. They need to be the same.
