This is my database structure: http://www.awesomescreenshot.com/image/733881/57d01b042ca99b9a36dde90dd6640cdc I would like to loop through all the child elements (those who's parent_id is set to the data_id within the same table). Therefore those with "parent_id" as "0" are parents, and those with parent_id with a number in it is a child. I would like help creating a function that will generate tables, with the table itself as the parent, and all the rows within it would be children of that parent. There is only one layer of depth in this project (one parent and one child layer always. ). Can anyone help, or would want a more detailed description? Thank you, and looking forward to a reply.

Hi Guys, I have the below code that I am trying to make work correctly, basically it creates a menu structure and then should only make the parent active if the page you are on belongs to that parent. at the moment the structure is wrong as it is adding too many <ul> entries for each menu. this is what it currently does: <ul id="nav"> <li class="active"><a href="admin.php">System Settings</a> <ul id="nav"> <li><a href="reports.php">Reports</a></il> </ul> <ul id="nav"> <li><a href="memblst.php?opt=createuser">Create User</a></il> </ul> </li> </ul> This is what it should be: <ul id="nav"> <li class="active"><a href="admin.php">System Settings</a> <ul> <li><a href="reports.php">Reports</a></il> <li><a href="memblst.php?opt=createuser">Create User</a></il> </ul> </li> </ul> $MENU["SYSTEMS"] = array ( 'parent'=>true, 'enabled'=>true, 'text'=>'System Settings', 'link'=> 'admin.php', 'sub_modules' => array('REPORTS','CREATE_USER') ); $MENU["REPORTS"] = array ( 'parent'=>FALSE, 'enabled'=>true, 'text'=>'Reports', 'link'=> 'reports.php', 'sub_modules' => array() ); $MENU["CREATE_USER"] = array ( 'parent'=>FALSE, 'enabled'=>true, 'text'=>'Create User', 'link'=> 'memblst.php?opt=createuser', 'sub_modules' => array() ); $MENU["MEMBER_LST"] = array ( 'parent'=>FALSE, 'enabled'=>true, 'text'=>'Member List', 'link'=> 'memberlst.php', 'sub_modules' => array() ); $MENU["SYSTEM_LOGS"] = array ( 'parent'=>FALSE, 'enabled'=>true, 'text'=>'System Logs', 'link'=> 'syslog.php', 'sub_modules' => array() ); function show_menu(&$MENU,$subIndex=false){ $menu_string = ''; $menu_string .= '<ul id="nav">'; if(!$subIndex){ foreach($MENU as $item) { if( $item['enabled']&&$item['parent'] ) { $_subString=""; if(!empty($item['sub_modules'])){ foreach($item['sub_modules'] as $sub){ $_subString .= show_menu($MENU,$sub); } } $menu_string .= '<li class="active"><a href="'.$item['link'].'">'.$item['text'].'</a>'.$_subString.'</li>'; } } }else{ if(@$MENU[$subIndex]['enabled']&&!@$MENU[$subIndex]['parent']) { $_subString=""; if(!empty($MENU[$subIndex]['sub_modules'])){ foreach($MENU[$subIndex]['sub_modules'] as $sub){ $_subString .= show_menu($MENU,$sub); } } $menu_string .= '<li><a href="'.$MENU[$subIndex]['link'].'">'.$MENU[$subIndex]['text'].'</a></il>'.$_subString; } } return $menu_string.'</ul>'; } echo show_menu($MENU);

Hi there! I am currently trying to edit a wordpress theme, and with my limited knowledge, I got stuck first thing., I have just added a subpage to a page on my blog for the first time, and would love to display a list in the sidebar on the parent that displays the parent itself, and all children. On the childpages, this same list (parent+children) should be visible. So, let's say I have a page called: contact, with subpages like 'route' and 'form', it should look like this, on the parentpage (contact) and the children: Contact Route Form On pages that do not have children, there should be no list. Looking through the wordpress codex, I found the following code to add to my sidebar.php: <?php //if the post has a parent if($post->post_parent){ //collect ancestor pages $relations = get_post_ancestors($post->ID); //get child pages $result = $wpdb->get_results( "SELECT ID FROM wp_posts WHERE post_parent = $post->ID AND post_type='page'" ); if ($result){ foreach($result as $pageID){ array_push($relations, $pageID->ID); } } //add current post to pages array_push($relations, $post->ID); //get comma delimited list of children and parents and self $relations_string = implode(",",$relations); //use include to list only the collected pages. $sidelinks = wp_list_pages("title_li=&echo=0&include=".$relations_string); }else{ // display only main level and children $sidelinks = wp_list_pages("title_li=&echo=0&depth=1&child_of=".$post->ID); } if ($sidelinks) { ?> <h2><?php the_title(); ?></h2> <ul> <?php //links in <li> tags echo $sidelinks; ?> </ul> <?php } ?> This works perfect on a child page, displaying child and parent in a neat linkable list. But on the parent page it only displays the child. How can I also add the parent there? Thank you in advance for your help!

I have a multi-dimensional array (something as below). What am trying to do is find a specific value, and if that value has children, list only those children. So for example, if am searching for slug's "test", then all of "test's" children list on the page. "Test2" has no children, so none listed. If am searching for "/test/sub" (the slug), and since it has children, I wanted to show all of the children (eg. "sh", "rd", "co"). I have only a code for checking a multi-dimensional array, but am lost as to how to go beyond that. function in_array_r($needle, $haystack, $strict = true) { foreach ($haystack as $item) { if (($strict ? $item === $needle : $item == $needle) || (is_array($item) && in_array_r($needle, $item, $strict))) { return true; } } return false; } Array ( [test] => Array ( [children] => Array ( [2] => Array ( [parent] => 4 [title] => Sub [slug] => test/sub/ [id] => 2 [children] => Array ( [3] => Array ( [parent] => 2 [title] => sh [slug] => test/sub/sh [id] => 3 ) [27] => Array ( [parent] => 2 [title] => RD [slug] => test/sub/rd [id] => 27 ) [145] => Array ( [parent] => 2 [title] => cO [slug] => test/sub/co [id] => 145 ) ) ) [8] => Array ( [parent] => 4 [title] => sub2 [slug] => test/sub2 [id] => 8 ) [19] => Array ( [parent] => 4 [title] => sub3 [slug] => test/sub3 [id] => 19 [children] => Array ( [20] => Array ( [parent] => 19 [title] => child1 [slug] => test/sub3/child1 [id] => 20 ) [21] => Array ( [parent] => 19 [title] => child2 [slug] => test/sub3/child2 [id] => 21 ) ) )
