How do I disply an array inside a custom post type?

Question

I tried to create a table output with the content of a custom post.

I can echo my city properly:

<span style="font-weight: bold;">city: </span>
<?php echo get_post_meta($post->ID, 'ptn_plaats', true);?>

But with this next line I get echo me ARRAY instead one of the options !!

<span style="font-weight: bold;">Systeem :</span>
<?php echo get_post_meta($post->ID, 'ptn_systeem', true);;?>

How can I echo the contents of my custom post type?

Answer 1

You got ARRAY echos because you saved array on post meta,

Just check array values of meta data like:

print_r( get_post_meta($post->ID, 'ptn_systeem', true) );

and echo it like:

foreach( (array) get_post_meta($post->ID, 'ptn_systeem', true) as  $option):

    echo $option . "<br>";

endforeach;

Please go through serialize array concept in wp.In your postmeta it is storing data in serialised form if you are getting an array. Either you can loop through the array or to fetch a single record use the array key.
