List posts in the wordpress theme customiser - php

Question

Hey there. I am creating a Wordpress theme and was wondering if anyone knew of a way to list one of my custom post types in the theme customiser. I have a custom post type called "slideshow" that has custom meta boxes etc and is designed just for slideshows. I would like to be able to list these posts in a dropdown inside the customiser. Ideally ending up with them in the array like this...
'the_id' => 'Slideshow post title',
$wp_customize->add_setting(
'slideshow-homepage',
array(
'default' => 'none',
)
);
$wp_customize->add_control(
'slideshow-homepage',
array(
'type' => 'select',
'priority' => 3,
'label' => 'Slideshow',
'description' => '',
'section' => 'homepage',
'choices' => array(
'somehow' => 'somehow',
'list' => 'list',
'all' => 'all',
'custom' => 'custom',
'post' => 'post',
'types' => 'types',
'of' => 'of',
'type' => 'type',
'slideshow' => 'slideshow'
),
)
);
Many thanks guys and girls. Lewis

Answer 1

use array_reduce
$wp_customize->add_control(
'slideshow-homepage',
array(
'type' => 'select',
'priority' => 3,
'label' => 'Slideshow',
'description' => '',
'section' => 'homepage',
'choices' => array_reduce(
get_posts( 'post_type=slideshow&posts_per_page=-1' ),
function( $result, $item ) {
$result[$item->ID] = $item->post_title;
return $result;
}
),
)
);
To add an empty field as well:
$posts = array_reduce(
get_posts( 'post_type=slideshow&posts_per_page=-1' ),
function( $result, $item ) {
$result[$item->ID] = $item->post_title;
return $result;
}
);
$none = array('' => 'None');
$choices = $none + $posts;
$wp_customize->add_control('slideshow_control', array(
'label' => __('Choose Slideshow', 'themename'),
'section' => 'slideshow_option',
'settings' => 'slideshow_settings',
'type' => 'select',
'choices' => $choices
));
