| // WORDPRESS function to get the sibling ID of a given post | |
| // this was created to avoid using a repetition patern like: | |
| // $current = $post->ID; | |
| // $parent = $post->post_parent; | |
| // $get_grandparent = get_post($parent); | |
| // $grandparent = $get_grandparent->post_parent; | |
| // $get_greatgrandparent = get_post($grandparent); | |
| // $greatgrandparent = $get_greatgrandparent->post_parent; | |
| // Like described in: http://andyweigel.com/great-grand-parent-ids-in-wordpress/ | |
| // this function takes in two arguments, the wordpress post object of the current page ($post) | |
| // and the $depth, this is the number of levels you want to go up so 1 is the parent, 2 is the grandparent ans so on... | |
| function get_siblings($post,$depth = 1) { | |
| $post_ID = $post->ID; | |
| $parent_ID = $post->post_parent; | |
| if ( $depth === 1 ) { | |
| return $parent_ID; | |
| } else { | |
| for ($i=2; $i <= $depth ; $i++) { | |
| if ( $i === 2 ) { $prev_sibling = $parent_ID; } else { $a = $i - 1; $prev_sibling = $sibling_ID_[$a]; } | |
| $get_sibling_ID_[$i] = get_post($prev_sibling); | |
| $sibling_ID_[$i] = $get_sibling_ID_[$i]->post_parent; | |
| } //endfor | |
| return $sibling_ID_[$depth]; | |
| } | |
