Overview
This Extra Field Type is available in WordPress Creation Kit Hobbyist or Pro. The Country Select Field creates a dropdown list with all countries.
Creating a Country Select Field
To add a Country Select Field to a previously created Custom Meta Box, under the Meta Box Fields tab simply insert a Field Title and under Field Type make sure you select Country Select.
The Country Select Field contains options to customize it:
- Description – Allows you to specify a description for the Country Select Field
- Required – Select whether the field is required or not
- Default Value – Set a default value for the Country Select Field
Page, Post or Custom Post Type Edit Screen
This is how the Country Select Field we created above looks like in the Edit Screen:
Template usage
The following examples are for a Custom Meta Box with the “Group Name” argument “my_meta_name“. Make sure to replace this with the “Group Name” you have set up. The Custom Meta Box below is setup to be attached to “Events” custom post type.
Using the WCK Custom Fields API
The Country Select Field returns a string.
For a Single Meta Box
To output a value inside The Loop we use the function the_cfc_field()
1 | Country: <?php the_cfc_field('my_meta_name', 'country'); ?> |
To asign the value to a variable we use the function get_cfc_field():
1 | <?php $country = get_cfc_field('my_meta_name', 'country'); ?> |
For a Repeater Meta Box
To output all the “Country” entries from the repeater field we use the functions get_cfc_meta() and the_cfc_field():
1 2 3 4 5 | <?php foreach( get_cfc_meta( 'my_meta_name' ) as $key => $value ){ the_cfc_field( 'my_meta_name','country', false, $key ); } ?> |
To output a specific “Country” entry from the repeater field (e.g. the second entry), we use the function the_cfc_field():
1 | <?php the_cfc_field( 'my_meta_name','country', false, 1 ); ?> |
The index starts at 0 so that’s why we pass “1” to the function. For the first entry it would be “0”, the second is “1”, the third is “2” and so on…
Using the default WordPress functions
The Country Select Field returns a string.
For a Single Meta Box
1 2 3 4 5 | <?php $my_meta = get_post_meta( $post->ID, 'my_meta_name', true ); if( !empty( $my_meta[0]['country'] ) ) echo 'Value:'.$my_meta[0]['country']; ?> |
For a Repeater Meta Box
To output all the “Country” entries in the repeater field:
1 2 3 4 5 6 7 8 | <?php $my_meta = get_post_meta( $post->ID, 'my_meta_name', true ); if( !empty( $my_meta ) ){ foreach( $my_meta as $entry ){ echo $entry['country']; } } ?> |
To output a specific “Country” entry from the repeater field (e.g. the second entry):
1 2 3 4 5 | <?php $my_meta = get_post_meta( $post->ID, 'my_meta_name', true ); if( !empty( $my_meta[1]['country'] ) ) echo $my_meta[1]['country']; ?> |
The index starts at 0 so that’s why we pass “1” to the function. For the first entry it would be “0”, the second is “1”, the third is “2” and so on…
