Suppose there is a page, Games and there are children of this page WarCraft, Half Life, Counter Strike. How to get me all the id pages of children? The fact is that you need to create a lot of parents and children. And that all the time not to look somewhere where id, I want them to just somewhere output, or receive, indicating "Parent". How to do this?

Use the get_page_children () function
<?php // ΠΠΎΠ»ΡΡΠΈΠΌ ΡΡΡΠ°Π½ΠΈΡΡ, ΠΏΠΎ ΠΊΠΎΡΠΎΡΡΠΌ Π±ΡΠ΄Π΅Ρ ΠΈΠ΄ΡΠΈ ΠΏΠΎΠΈΡΠΊ $my_wp_query = new WP_Query(); $all_wp_pages = $my_wp_query->query(array('post_type' => 'page')); // ΠΠ° ΠΏΡΠΈΠΌΠ΅ΡΠ΅ ΡΡΡΠ°Π½ΠΈΡΡ Ρ id = 2 $page_id = 2; // Π€ΠΈΠ»ΡΡΡΡΠ΅ΠΌ ΡΡΡΠ°Π½ΠΈΡΡ ΠΏΠΎΠ»ΡΡΠ΅Π½Π½ΠΎΠ³ΠΎ ΡΠ°Π½Π΅Π΅ ΠΌΠ°ΡΡΠΈΠ²Π° $all_wp_pages ΠΈ Π½Π°Ρ

- Thanks for your code, it does not work, I substituted the ID of the pages, the parents, the children were not output. - KernelByte
- it's strange because everything worked fine for me - alenkins
- I do not have, inserted in single.php where the post is displayed, and nothing. Inserted different pages of pages, too. Checked, array "$ page_childrens" and it is empty! maybe somewhere there is an error in getting the children page. - KernelByte

But thanks, in the meantime, I found the answer on another source, and I didnβt redid the code a lot, let's say I brought it to a normal view, and output the results.
<?php function get_all_pages($page_title) { $page = get_page_by_title($page_title); if (empty($page)) return array(); $children = new WP_Query( array( 'post_type' => 'page', 'post_parent' => $page->ID, 'fields' => 'ids', 'posts_per_page' => -1 //ΠΠΎΠΊΠ°ΠΆΠ΅ΠΌ Π²ΡΠ΅Ρ

Thanks for the help.
