Yes, i already revised the code and this works:
function post_object_navigation_shortcode() {
global $post;
// get the post/page id where post object field is added.
$course_id = get_field( 'lesson_of_course' );
// get current post id, this can be also a post object.
$current_post_link_id = get_the_ID();
// get all the post_link sub field values.
$post_objects = array();
if ( have_rows( 'lesson_listing', $course_id ) ) :
while ( have_rows( 'lesson_listing', $course_id ) ) :
the_row();
// check for rows (sub repeater)
if ( have_rows( 'section_repeater', $course_id ) ) :
while ( have_rows( 'section_repeater', $course_id ) ) :
the_row();
$my_field = get_sub_field( 'post_link' );
if ( ! empty( $my_field ) ) {
$post_objects[] = $my_field;
}
endwhile;
endif;
endwhile;
endif;
// get the current index of the current post object
$current_index = array_search( $current_post_link_id, array_column( $post_objects, 'ID' ) );
// output the previous post object title and link
if ( $current_index > 0 ) {
$previous_post = $post_objects[ $current_index - 1 ];
$post = get_post( $previous_post );
setup_postdata( $post );
$title = get_the_title();
$link = get_the_permalink();
echo '<a href="' . esc_url( $link ) . '">' . esc_html( $title ) . '</a>';
}
// output the next post object title and link
if ( $current_index < count( $post_objects ) - 1 ) {
$next_post = $post_objects[ $current_index + 1 ];
$post = get_post( $next_post );
setup_postdata( $post );
$title = get_the_title();
$link = get_the_permalink();
echo '<a href="' . esc_url( $link ) . '">' . esc_html( $title ) . '</a>';
}
wp_reset_postdata();
}
add_shortcode( 'lesson_navigation', 'post_object_navigation_shortcode' );
Hi, it not allow multiple selections, single selection for each post object (shared in 2nd reply).
Here what i have tried, seems to work now:
// Shortcode [post_grid]
if ( ! function_exists('post_grid_shortcode') ) {
function post_grid_shortcode( $atts ){
global $post;
if( have_rows('post_grid') ):
while( have_rows('post_grid') ): the_row();
// 2
$featured_posts = get_sub_field('ranking');
if( $featured_posts ):
$permalinkx = get_permalink( $featured_posts->ID );
$titlex = get_the_title( $featured_posts->ID );
$permalink = get_the_permalink();
$title = get_the_title();
echo '<a href="'.$permalink.'" class="11">'.$title.'</a>';
echo '<a href="'.$permalinkx.'" class="11">'.$titlex.'</a>';
endif;
//2
endwhile;
endif;
}
}
add_shortcode('post_grid', 'post_grid_shortcode');
This code seems to work but output sample-page and few blank HTML. It seems like i am missing something simple.
// Shortcode [post_grid]
if ( ! function_exists('post_grid_shortcode') ) {
function post_grid_shortcode( $atts ){
global $post;
if( have_rows('post_grid') ):
while( have_rows('post_grid') ): the_row();
// 2
$featured_posts = get_sub_field('ranking');
if( $featured_posts ):
//
foreach( $featured_posts as $post ):
setup_postdata($post);
//foreach( $featured_posts as $featured_post ):
$permalink = get_permalink( $featured_post->ID );
$title = get_the_title( $featured_post->ID );
?>
<a href="<?php echo esc_url( $permalink ); ?>" class="10"><?php echo esc_html( $title ); ?></a>
<a href="<?php the_permalink(); ?>" class="11"><?php the_title(); ?></a>
<?php
//endforeach;
endforeach;
wp_reset_postdata();
//
endif;
//2
endwhile;
endif;
}
}
add_shortcode('post_grid', 'post_grid_shortcode');
Here is the current setup in screenshot:
