I have written a custom shortcode (see below) and placed it in the functions.php file of my child theme.
The aim of the shortcode is to retrieve the title of a previously created custom post. In this case the custom post type I created is titled 'publications_test' from the ID of the post.
For example, [testshorctode id=427] would output the title of the post whose ID is 427. Unfortunately, the code is producing a WSOD and I'm not sure where I am going wrong.
Any help would be greatly appreciated. I am by no means a web developer, so I apologize for any obvious error.
function register_shortcodes() {
add_shortcode( 'testshortcode', 'testshortcode_function' );
}
add_action( 'init', 'register_shortcodes' );
function testshortcode_function($atts) {
extract( shortcode_atts(
'post_type' => 'publications_test',
'post_status' => 'publish'
'id' => '',
);
global $post;
$string = '';
$query = new WP_Query( $atts );
if( $query->have_posts() ){
$string .= '<ul>';
while( $query->have_posts() ){
$query->the_post();
$string .= '<li>' . get_the_title() . '</li>';
}
$string .= '</ul>';
}
wp_reset_postdata();
return $string;
}

Reset to default 2 extract( shortcode_atts(
'post_type' => 'publications_test',
'post_status' => 'publish'
'id' => '',
);
The above is wrong. You have an array inside that function but it's not in an actual array. Try this instead:
extract( shortcode_atts(array(
'post_type' => 'publications_test',
'post_status' => 'publish',
'id' => '',
), $atts, 'testshortcode');
