Ajax call within WordPress returning entire HTML page in response

The most frustrating thing is that this code was working then suddenly it startet returning an entire page of HTML rather than just the HTML code from the template below.
I'm calling an ajax function and passing it an object that looks like this (result of console.log(data)):
Here is my ajax function:
function mapResults (data) {
//console.log(data);
$.ajax({
type: 'post',
url: wp_ajax.wp_url,
data: {action: 'marker_in_viewport', resultsArray: data},
success: function(result) {
$('#map-results').html(result);
},
error: function(result) {
console.warn(result);
}
});
}
Here is the PHP code that handles the request:
<?php
add_action( 'wp_ajax_nopriv_marker_in_viewport', 'marker_in_viewport');
add_action( 'wp_ajax_marker_in_viewport', 'marker_in_viewport');
function marker_in_viewport() {
$locationResults = $_POST['resultsArray'];
$posts = get_posts(array(
'post_type' => 'accommodation',
'post__in' => $locationResults,
));
?>
<?php
//require result template
//require_once ('map-results.php');
if( $posts ) { ?>
<?php foreach( $posts as $post ) {
$id = $post->ID;
$title = get_the_title($id);
$location = get_field('location', $id);
$permalink = get_permalink( $id );
$rooms_available_from = get_field('rooms_available_from', $id);
$gallery = get_field('gallery', $id);
?>
<div class="col-md-4 accom-results-cont pb-3">
<?php if ($gallery) : ?>
<a href="<?= $permalink; ?>" title="Learn more about <?= $title; ?>">
<div class="accom-results-img-cont">
<img class="img-fluid" src="<?= $gallery['url']; ?>" alt="An image of <?= $title; ?>" >
</div>
<?php endif; ?>
<div class="accom-results-data-cont pr-3 pt-3">
<?php if ( $title ) : ?>
<p class="results-title"><b><?= $title ?></b></p>
<?php endif; ?>
</div>
</a>
</div>
<?php } ?>
<?php } ?>
<?php wp_die(); ?>
<?php } ?>
And in my page template I have the following div where I want the results to be populated:
<div id="map-results"class="row py-5"></div>
Any ideas what I have done wrong?

I revised your code. try the below code.
function mapResults (data) {
$.ajax({
type: 'post',
dataType : "json",
url: wp_ajax.wp_url,
data: {action: 'marker_in_viewport', resultsArray: data},
success: function(result) {
$('#map-results').html(result.data.html);
},error: function(result) {
console.warn(result);
}
});
}
You can use ob_start() and ob_get_clean().
add_action( 'wp_ajax_nopriv_marker_in_viewport', 'marker_in_viewport');
add_action( 'wp_ajax_marker_in_viewport', 'marker_in_viewport');
function marker_in_viewport() {
$locationResults = $_POST['resultsArray'];
$posts = get_posts(array(
'post_type' => 'accommodation',
'post__in' => $locationResults
));
ob_start();
if( $posts ) { foreach( $posts as $post ) {
$id = $post->ID;
$title = get_the_title($id);
$location = get_field('location', $id);
$permalink = get_permalink( $id );
$gallery = get_field('gallery', $id);
$rooms_available_from = get_field('rooms_available_from', $id);
?>
<div class="col-md-4 accom-results-cont pb-3">
<a href="<?php echo $permalink; ?>" title="Learn more about <?php echo $title; ?>">
<?php if ( $gallery ) : ?>
<div class="accom-results-img-cont">
<img class="img-fluid" src="<?php echo $gallery['url']; ?>" alt="An image of <?php echo $title; ?>" >
</div>
<?php endif; ?>
<div class="accom-results-data-cont pr-3 pt-3">
<?php if ( $title ) : ?>
<p class="results-title"><b><?php echo $title; ?></b></p>
<?php endif; ?>
</div>
</a>
</div>
<?php } }
$html = ob_get_clean();
wp_send_json_success(array(
'html' => $html
));
}
USEFUL LINKS
ob_start()
ob_get_clean()
wp_send_json_success()

Finally got this working after about a week of trying!!
Here is my AJAX Function inside js/script.js
$.ajax({
type: 'post',
//dataType: 'json',
url: map_ajax_obj.ajaxurl,
data: {action: 'marker_in_viewport', resultsArray: data, nonce: map_ajax_obj.nonce},
success: function(result) {
//console.log(result);
$('#map-results').html(result);
},
error: function(result) {
console.warn(result);
}
});
Inside my functions.php file I have enqueued and localised my wp-admin.php like this
function load_req_scripts()
{
wp_register_script( 'custom-js-script', get_template_directory_uri() . '/js/script.js', array( 'jquery'), '', true);
wp_enqueue_script( 'custom-js-script' );
wp_localize_script(
'custom-js-script', //I think this is a dependancy on the above script though not entirely sure
'map_ajax_obj',
array (
'ajaxurl' => admin_url('admin-ajax.php'),
'nonce' => wp_create_nonce('ajax_nonce')
)
);
}
add_action( 'wp_enqueue_scripts', 'load_req_scripts' );
require_once('ajax/accommodation-ajax.php'); //where to handle and return the data to the ajax call
here is the function in my accommodation-ajax.php file
<?php
function marker_in_viewport() {
$locationResults = $_POST['resultsArray'];
if (!empty($locationResults)) {
$posts = get_posts(array(
'post_type' => 'accommodation',
'post__in' => $locationResults
));
if( $posts ) {
foreach( $posts as $post ) {
$id = $post->ID;
$title = get_the_title($id);
$location = get_field('location', $id);
$permalink = get_permalink( $id );
$gallery = get_field('gallery', $id);
$rooms_available_from = get_field('rooms_available_from', $id);
?>
<div class="col-md-4 accom-results-cont pb-3">
<a href="<?php echo $permalink; ?>" title="Learn more about <?php echo $title; ?>">
<?php if ( $gallery ) : ?>
<div class="accom-results-img-cont">
<img class="img-fluid" src="<?php echo $gallery['url']; ?>" alt="An image of <?php echo $title; ?>" >
</div>
<?php endif; ?>
<div class="accom-results-data-cont pr-3 pt-3">
<?php if ( $title ) : ?>
<p class="results-title"><b><?php echo $title; ?></b></p>
<?php endif; ?>
</div>
</a>
</div>
<?php } //end for each
} //end if posts
} //end if not empty
else {
echo "No results found please search again!";
}
wp_die();
}
add_action( 'wp_ajax_nopriv_marker_in_viewport', 'marker_in_viewport');
add_action( 'wp_ajax_marker_in_viewport', 'marker_in_viewport');
As to why this now works compared to what I posted above I have no idea!! Could it be the NONCE? though I'm not using it to authenticate in the PHP function. Anyway hope this helps someone or my future self next time I'm banging my head against the wall with wordpress ajax calls.
UPDATE So this stopped working for me again then I realised that it was working when logged in as admin and not workign for logged out and all other users. Because this is a membership site I wanted to block anyone that wasn't an admin form the admin area. Didn't realise that this function was also blocking access to the admin-ajax.php file too. This was redirecting to the Homepage hence why the AJAX call was returning the entire page HTML.
SO I needed to update my function to include:
&& ( ! defined( 'DOING_AJAX' ) || ! DOING_AJAX )
to the following:
//block users from admin if not admin
function blockusers_wps_init() {
if ( is_admin() && ! current_user_can( 'administrator' ) && ( ! defined( 'DOING_AJAX' ) || ! DOING_AJAX ) ) {
wp_redirect( home_url() );
exit;
}
}
add_action( 'init', 'blockusers_wps_init' );

Don’t use wp_die() it’s returning html, use just die()

How can I change this javascript so it does target my code for this Ajax filter?

I want an Ajax filter for my WordPress catagories.
The script I show here is targeting a select dropdown, but I want to have some buttons instead.
My Javascript knowledge isn't 100%, so I don't know how I can change some to be able to use buttons instead of the dropdown.
Can you help me out here?
I tried to change the html code to input:radio, and then change the javascript to onclick, but it doesn't work. The filter keeps showing all.
The only way it works is with the dropdown.
The script I used was found on
http://dominykasgel.com/ajax-posts-filter/
The Javascript I used.
jQuery( ".js-category, .js-date" ).on( "change", function() {
var category = $( '.js-category' ).val();
var date = $( '.js-date' ).val()
data = {
'action': 'filterposts',
'category': category,
'date': date
};
$.ajax({
url : ajaxurl,
data : data,
type : 'POST',
beforeSend : function ( xhr ) {
$('.filtered-posts').html( 'Laden...' );
$('.js-category').attr( 'disabled', 'disabled' );
$('.js-date').attr( 'disabled', 'disabled' );
},
success : function( data ) {
if ( data ) {
$('.filtered-posts').html( data.projecten );
$('.js-category').removeAttr('disabled');
$('.js-date').removeAttr('disabled');
} else {
$('.filtered-posts').html( 'Helaas, er zijn geen projecten gevonden.' );
}
}
});
});
The php code I used for the functions.php
function ajax_filterposts_handler() {
$category = esc_attr( $_POST['category'] );
$date = esc_attr( $_POST['date'] );
$args = array(
'post_type' => 'projecten',
'post_status' => 'publish',
'posts_per_page' => -1,
'orderby' => 'date',
'order' => 'DESC'
);
if ( $category != 'all' )
$args['cat'] = $category;
if ( $date == 'new' ) {
$args['order'] = 'DESC';
} else {
$args['order'] = 'ASC';
}
$posts = 'Helaas, er zijn geen projecten gevonden.';
$the_query = new WP_Query( $args );
if ( $the_query->have_posts() ) :
ob_start();
while ( $the_query->have_posts() ) : $the_query->the_post();
get_template_part( 'includes/content-post' );
endwhile;
$posts = ob_get_clean();
endif;
$return = array(
'projecten' => $posts
);
wp_send_json($return);
}
add_action( 'wp_ajax_filterposts', 'ajax_filterposts_handler' );
add_action( 'wp_ajax_nopriv_filterposts', 'ajax_filterposts_handler' );
The code for in the archive.php file:
<div class="filter-wrap">
<div class="category">
<!-- <div class="field-title">Category</div> -->
<?php $get_categories = get_categories(array('hide_empty' => 0)); ?>
<select class="js-category">
<option value="all">alles</option>
<?php
if ( $get_categories ) :
foreach ( $get_categories as $cat ) :
?>
<option value="<?php echo $cat->term_id; ?>">
<?php echo $cat->name; ?>
</option>
<?php endforeach;
endif;
?>
</select>
</div>
</div>
<div class="filtered-posts">
<?php
if ( have_posts() ) :
while ( have_posts() ) : the_post();
get_template_part( 'includes/content-post' );
endwhile;
endif;
?>
</div>
The code for my content-post.php:
<article id="post-id-<?php the_id(); ?>" <?php post_class('clearfiks archive-projecten'); ?>>
<a href="<?php the_permalink() ?>"><h3><?php the_title(); ?></h3>
</article>

How to add owl carousel to front page

I'm using a pre made theme for my site. I would like to add an owl carousel to the top of my front page that displays the most popular posts from the last month on my site. The pre made theme already comes with owl carousel. So my question is how can I add the carousel to my front page now? I found the owl carousel widget in the plugins file so I tried adding the widget to my front page but I don't think I added it right because nothing changed. Does anyone have any suggestions for how I could achieve this?
here are my full theme files if needed - https://www.dropbox.com/s/624p2sdn2i0jsqf/novablogshare.zip?dl=0

#user6738171 I believe you do not need to the_widget("owl_Widget"); Just build the html you would like to show(using php) and then call the carousel with JQuery like so:
jQuery(document).ready(function($){
$(".homepage-slides").owlCarousel({
items: 1,
nav: true,
dots: false,
autoplay: true,
loop: true
});
});
Please read documentation for the correct structure of carousel items https://github.com/OwlCarousel2/OwlCarousel2. If you need help for building the carousel let me know. :-)

Something like this:
<?php
?>
<div class="homepage-slides">
<div>
<?php the_post_thumbnail('thumbnail', array('class' => 'thumbnail')); ?>
<?php the_title(); ?>
<?php the_excerpt(); ?>
</div>
</div>
<?php
And the jquery from above. Inside the loop of course

Try this code it loops through the posts with the custom query you provided and puts them out accordingly. The only thing you should have to do is calculate how many posts you want to show and edit the carousel count.
<?php
$month = date('m');
$year = date('Y');
$new_query = new WP_Query( array('posts_per_page' => $carousel_count, 'meta_key' => 'wpb_post_views_count', 'orderby' => 'meta_value_num', 'order' => 'DESC','monthnum'=>$month,'year'=>$year ));
?>
<?php if ( $new_query->have_posts() ) : ?>
<div class="homepage-slides">
<?php while ( $new_query->have_posts() ) : $new_query->the_post(); ?>
<div>
<?php the_post_thumbnail('thumbnail', array('class' => 'thumbnail')); ?>
<?php the_title(); ?>
<?php the_excerpt(); ?>
</div>
<?php endwhile; wp_reset_postdata(); ?>
</div>
<?php else : ?>
<p><?php _e(); ?></p>
<?php endif; ?>
<script>
jQuery(document).ready(function($){
$(".homepage-slides").owlCarousel({
items: 4,
nav: true,
dots: false,
autoplay: true,
loop: true
});
});
</script>

Can you remove wordpress post tags with js/php after certain date (ACF date time picker)?

So my website lists upcoming film screenings in my area.
I'm using the ACF date time picker to only show posts/film screenings that are in the future in the wordpress loop.
I have tags filtering the results dynamically using ajax (thanks to https://www.bobz.co/ajax-filter-posts-tag/) except there are tags that aren't relevant to the results because they belong to posts that are older than the current date (past screenings).
*For example on the website, the 'animated film festival' is still coming up with the other tags.
I don't know if it's possible to delete a posts tags with PHP (within the post template while it loops through other posts) - and to delete the posts tags if the ACF date time field for that post is older than the current date.
I haven't found much luck googling this and I am a bit of a noob so...
This is my site: http://pigcine.pamrosel.com/
This is what I'm doing in my functions.php file at the moment:
// Get all tags and display
function tags_filter() {
$tax = 'post_tag';
$terms = get_terms( $tax );
$count = count( $terms );
if ( $count > 0 ): ?>
<div class="post-tags">
<?php
foreach ( $terms as $term ) {
$term_link = get_term_link( $term, $tax );
echo '' . $term->name . ' ';
} ?>
</div>
<?php endif; }
// Script for getting posts
function ajax_filter_get_posts( $taxonomy ) {
// Verify nonce
if( !isset( $_POST['afp_nonce'] ) || !wp_verify_nonce($_POST['afp_nonce'], 'afp_nonce' ) )
die('Permission denied');
$taxonomy = $_POST['taxonomy'];
// WP Query
$args = array(
'tag' => $taxonomy,
'post_type' => 'post',
'posts_per_page' => -1,
'meta_key' => 'datetime',
'orderby' => array(
'datetime' => 'ASC'
),
);
// If taxonomy is not set, remove key from array and get all posts
if( !$taxonomy ) {
unset( $args['tag'] );
}
$query = new WP_Query( $args );
if ( $query->have_posts() ) : while($query->have_posts()) : $query>the_post();
$today = date('Y-m-d H:i:s', strtotime('+9 hours'));
$event_date = get_field('datetime');
if (strtotime($today) <= strtotime($event_date)) {
?>
<div class="sl">
<div class="sl_closed">
<div class="col-2-8"><div class="modulepad">
<p><?php the_field('datetime'); ?></p>
</div></div>
<div class="col-3-8"><div class="modulepad">
<p><?php the_title(); ?><br>
<?php $wpmovieinput = get_field('movie_title'); $movie = imdb_connector_get_movie($wpmovieinput); echo implode(", ", $movie["directors"]); ?>
</p>
</div></div>
<div class="col-3-8"><div class="modulepad">
<p><?php the_field('location_name'); ?><br>
<?php $wpmovieinput = get_field('movie_title'); $movie = imdb_connector_get_movie($wpmovieinput); echo implode(", ", $movie["countries"]) . " "; echo $movie["released"] . " "; echo implode(", ", $movie["runtime"]); ?>
</p>
</div></div>
</div><!--SL_CLOSED-->
<?php } endwhile; ?>
<?php else: ?>
<h2>No posts found</h2>
<?php endif;
die();

How to save PHP variable in loop after AJAX requests more posts?

I have been looking at this code for far too long and am getting nowhere so hopefully someone can help me!
I am building a wordpress site, and for the main blog page, I want to display the content as tiles, but every 3 or 7, I want to display a promo content post-type. I can do this fine, but when I add a Load More Posts button, it resets the counter that I have keeping track of my extra promo content back to 0, therefore only showing the first 2 promo pieces over and over with each new load.
I would appreciate any help. I'm going in circles now.
the important parts of the home.php file :
<div class="blog-post-tiles">
<?php
//variables
$counter = 0;
$promo_counter = 0;
$args = array(
'post_type' => 'promo',
);
//$postlist = new WP_Query( $args );
$postlist = get_posts($args);
$posts = array();
foreach ( $postlist as $post ) {
$promo_posts_array[] += $post->ID;
}
?>
<?php if ( have_posts() ) : ?>
<?php $query = new wp_query( $query_string.'&cat=-16' );
while ( $query->have_posts() ) : $query->the_post() ?>
<?php
// print post loop
get_template_part( 'template-parts/content', get_post_format() );
$counter++;
//display promo content ever 3rd or 10th spot
if (($counter == 3) || ($counter % 10 == 0) || ($counter % 10 == 3)) {
if ($promo_counter < count($promo_posts_array)){
$print_post = $promo_posts_array[$promo_counter];
$promo_thumbnail_src = wp_get_attachment_image_src( get_post_thumbnail_id($print_post), array( 200,200 ), false, '');
?>
<div class="posts_page_tile promo-tile" id="id-<?php echo $print_post; ?>">
<div class="entry-content">
<div class="promo-image" style="background-image:url('<?php echo $promo_thumbnail_src[0]; ?>'); background-color:<?php echo get_post_meta($print_post, 'bgcolor', true) ?>">
<h3><?php echo get_the_title($print_post); ?></h3>
<div class="promo_button_white_border"><?php echo get_post_meta($print_post, 'cta', true); ?>
</div>
</div>
</div>
</div>
<?php
}
$promo_counter++;
wp_reset_postdata();
}
?>
<?php endwhile; ?>
I'm using this load more posts plugin.
