I am using this code:

for($x = 0;$x<100;$x++) {
		$list_array[ $x ]['year'] = get_post_meta($list_posts[$x], 'copyrightyear', true);
		$list_array[ $x ]['imdb'] = get_post_meta($list_posts[$x], 'imdb_rating', true);
		$list_array[ $x ]['title'] = get_the_title($list_posts[$x]);
		$list_array[ $x ]['url']   = get_the_permalink($list_posts[$x]);
		
	}
	
	echo wp_json_encode( array( 'items' => $list_array ) );
	return wp_json_encode( array( 'items' => $list_array ) );

I have tried esc_html(get_the_title($list_posts[$x])); as well.

But somehow the output is not showing the correct format. It’s showing [&-#8217;], [&-#038;], etc.

How do I modify the output?
Regards

I am having problems trying to access to my site. This is the message:

Fatal error: Call to undefined function wp_json_encode() in /usr/home/doordresserblog.com/web/wp-includes/class.wp-scripts.php on line 186

I have downloaded the file class.wp-scripts.php but I don’t really know what I have to do with it.

Could you help me please?

Thank you!

I’m working in a wordpress project with two custom post type (documentaries and scenes) and a custom taxonomy (production). Each documentary has many scenes, and I’d like to display a map with all theses scenes in the scene view. So I create two custom fields for scene’s post type: longitude and latitude.

I choose to use Leaflet.js directly, without any plugin. So I enqueued all css and js libraries to my theme, and wrote the following code in a template part, following these instructions from Andy. But this lines brakes my page.

The main idea is to create a new WP_Query() selecting only the scenes which shares the custom taxonomy, iterate throught the results and add an array with desired data (name, url, lng and lat) to a previously defined array called ‘geodata’.

Can some of you review what is wrong please?

<?php
/**
 * @package Illes de futur
 */
?>

<section id="scene-map">

	<div id="map" style="heigth: 440px; border: 1px solid #aaa;"></div>

	<?php

	  	$terms = get_the_term_list( $post->ID, 'production' );
	  	$id = get_the_ID();

	  	$args = array(
	  		'post_type' => 'scene',
	  		'tax_query' => array(
	  			'taxonomy' => 'production',
	  			'field' => 'slug',
	  			'terms' => $terms,
	  			),
	  		'exclude' => $id
	  		);

		$geodata = array();

		$geolocated_scenes = new WP_Query($args);

		if( $geolocated_scenes->have_posts() ) :

			while( $geolocated_scenes->have_posts() ) : $geolocated_scenes->the_post();

				$geodata[] = [
					'name' => get_the_title(),
					'url' => get_post_permalink(),
					'lat' => get_post_meta( the_ID(), 'latitude', true ),
					'lng' => get_post_meta( the_ID(), 'longitude', true ),
				];

			endwhile;

			wp_reset_postdata();

		else : ?>

			<p><?php __('This scene has not geolocation data', 'illles_de_futur'); ?></p>

		<? endif;

		echo wp_json_encode( $geodata );

	?>

	<script type="text/javascript">

		var map = L.map( 'map', {
			center: [20.0, 5.0],
			minZoom: 2,
			zoom: 2
		});

		L.tileLayer( 'https://{s}.mqcdn.com/tiles/1.0.0/map/{z}/{x}/{y}.png', {
			attribution:'&copy; <a href="https://osm.org/copyright" title="OpenStreetMap" target="_blank">OpenStreetMap</a> contributors | Tiles Courtesy of <a href="https://www.mapquest.com/" title="MapQuest" target="_blank">MapQuest</a><img src="https://developer.mapquest.com/osm/mq_logo.png" width="16" height="16" />',
			subdomains: ['otile1' , 'otile2' , 'otile3' , 'otile4']
		}).addTo( map );

		for ( var i=0; i < geodata.length; ++i )
		{
			L.geodata( [geodata[i].lat, geodata[i].lng] )
				.bindPopup( '<a href="' + geodata[i].url + '">' geodata[i].name + '</a>' )
				.addTo( map );
		}

	</script>

Thanks in advance!!!

Reading a bunch of things, but need specific direction on how to resolve this. I’m unable to login to the WordPress backend because the same error applies.

Thanks in advance.

I reinstalled all wp unless content and config, but the error continue.
