WordPress查询自定义帖子类型的自定义字段

Question

I have a custom post type 'orders' and there are a few custom fields attached to this post type.

When I query all orders like so:

$orders = new WP_Query( array( 'post_type' => 'orders') );

I don't get all the data I wish to get.

I have a tab custom field with a repeater in it. And I kinda need the data from the repeater. Anyone knows why I don't get this data in the dump of $orders ?

Should my query be something else to get all this data?

EDIT

I've managed to query this array:

Array
(
    [0] => Array
        (
            [0] => Array
                (
                    [attractie] => WP_Post Object
                        (
                            [ID] => 41
                            [post_author] => 1
                            [post_date] => 2016-02-29 14:30:33
                            [post_date_gmt] => 2016-02-29 14:30:33
                            [post_content] => <h2>Title!</h2>
                            Content.
                            [post_title] => Post Title
                            [post_excerpt] => 
                            [post_status] => publish
                            [comment_status] => closed
                            [ping_status] => closed
                            [post_password] => 
                            [post_name] => post-name
                            [to_ping] => 
                            [pinged] => 
                            [post_modified] => 2016-04-07 14:39:41
                            [post_modified_gmt] => 2016-04-07 14:39:41
                            [post_content_filtered] => 
                            [post_parent] => 0
                            [guid] => url
                            [menu_order] => 0
                            [post_type] => attracties
                            [post_mime_type] => 
                            [comment_count] => 0
                            [filter] => raw
                        )

                    [start] => 0930
                    [end] => 1200
                )

            [1] => Array
                (
                    [attractie] => 
                    [start] => 0930
                    [end] => 1200
                )

        )

With this code:

$orders = new WP_Query( array( 'post_type' => 'orders') );

foreach ( $orders->posts as $all ) {
   $fields[] = get_field( 'planning', $all->ID );
}

What I basically need now is the post_title value from the attractie WP_Post Object and the start and end values.

So far so good, you are already creating custom query:

$loopargs = array( //in the array are arguments for custom query            
   'post_type' => 'orders', //your CPT
   'posts_per_page' => -1, //lets make WP show them all
   'orderby' => 'date', // newest
   'order' => 'DESC', //to the top
); 
$query = new WP_Query($loopargs);

Now let us loop through it:

while ($query->have_posts()) : $query->the_post(); //the_post loads for you current post in loop so that you can use functions like the_title(), the_content(), etc..

about ACF Plugin:

the_field('your_field_name'); //will output field content directly the_field('your_field_name'); //will output field content directly get_field('your_field_name'); //returns value from your custom field get_field('your_field_name'); //returns value from your custom field get_fields(); //returns array of your fields get_fields(); //returns array of your fields

Note that those ACF plugin functions will work in loop only, in our case when we set up the post with the_post() in while loop everytime. Otherwise you need to pass POST_ID as second (in first two) and as first parameters in ACF functions.

Also not that we have to reset your query after every custom one. And of course to end up our loop.

endwhile; 
wp_reset_query();

EDIT

To access elements in your array from question you would do this:

$title = $array[0][0]['attractie']->post_title;
$start = $array[0][0]['start'];
$end = $array[0][0]['end'];

But this is really NOT the way you should do it.

Answer 2

There is a method to get acf fields try using like this

$orders = new WP_Query( array( 'post_type' => 'orders') );
foreach ( $orders->posts as $allPosts ) {
$field     = get_field( 'your field name', $allPosts->ID );
}

Answer 3

use get_post_custom function for getting list of custom Fields

get_post_custom($post_id);
