您必须从 post_loader 函数以 JSON 形式返回数据。我已经清理了一点,但仍然是一团糟。
// LOAD DEFAULT VALUES FROM DEFAULT TOUR
add_action('wp_ajax_post_loader', 'post_loader');
function post_loader() {
$post_id = $_POST["post_id"];
$args = array(
'p' => $post_id,
'numberposts'=> -1, // Fetch all posts...
'post_type'=> 'location_tour', // from the 'location_tour' CPT...
);
$location = new WP_Query( $args );
if ( $location->have_posts() ) :
while ( $location->have_posts() ) :
$location->the_post();
$title = the_field('title');
$description = the_field('description');
// You have to return data as json
wp_send_json([
'title' => $title,
'description' => $description
]);
//wp_reset_postdata();
endwhile;
endif;
// Why do you need this inside this function?
// add_action('acf/prepare_field/name=default_tour', 'post_loader');
}
JS
jQuery(document).on( 'click', '#data_fetch', function( dohvati ){
dohvati.preventDefault();
var post_id = jQuery('.acf-row .selection .values ul li span').data('id'); // This takes the post ID from the selected Post(Location/Tour) in the Relationship field
jQuery.ajax({
url: the_ajax_script.ajaxurl, //The URL that we set for the wordpress admin-ajax.php
type: "POST",
dataType: 'json',
data: {
action: 'post_loader', // This is the name of the php function
post_id: post_id,
},
success: function(data){
console.log(data)
jQuery("#acf-field_5cb991a9337db-row-0-field_5cbeabc041c8a").val(data.title); //This is replacing the title field - but the variables are missing
jQuery("#acf-field_5cb991a9337db-row-0-field_5cbeab8f41c89").val(data.description); //This is replacing the description field - but the variables are missing
},
error: function(error){
console.log(error)
},
});
});
