Invalid network operator not working

Question

For some reason, my triple statement assignment does not work for the second part of my array. Does anyone see what I'm doing wrong? It should just see if there is a value for the permalink field, and if not, then insert link_url into the array.

 function getSiteMap() { $this->db->select('site_menu_structures_links.id, site_menu_structures_links.link_name'); $this->db->from('site_menu_structures_links'); $this->db->where('site_menu_structures_links.status_id', 1); $this->db->where('site_menu_structures_links.is_category', 'Yes'); $this->db->order_by('site_menu_structures_links.sort_order'); $catQuery = $this->db->get(); if ($catQuery->num_rows()) { foreach ($catQuery->result() as $cats) { // Set the Main Category into the array $testArray[$cats->id] = array( 'id' => $cats->id, 'name' =>$cats->link_name ); $this->db->select('site_content_pages.permalink, site_menu_structures_links_children.id, site_menu_structures_links_children.link_url, site_menu_structures_links_children.link_name'); $this->db->from('site_menu_structures_links_children'); $this->db->join('site_content_pages', 'site_content_pages.id = site_menu_structures_links_children.site_content_pages_id'); $this->db->where('site_menu_structures_links_id', $cats->id); $this->db->where('site_menu_structures_links_children.status_id', 1); $this->db->order_by('site_menu_structures_links_children.sort_order'); $childrenQuery = $this->db->get(); if ($childrenQuery->num_rows()) { foreach ($childrenQuery->result() as $child) { $testArray[$cats->id]['children'][$child->id] = array( 'linke_url' => (empty($child->permalink)) ? $child->link_url : $child->permalink, 'link_name' => $child->link_name, ); } } } } return $testArray; } 

EDIT:

Also, there should not be 3 elements inside Social Array and not say what is. I am wondering if this is related to this connection. Here is my conclusion:

 Array ( [2] => Array ( [id] => 2 [name] => Roster [children] => Array ( [1] => Array ( [linke_url] => [link_name] => Superstars ) [2] => Array ( [linke_url] => [link_name] => Champions and Contenders ) [3] => Array ( [linke_url] => [link_name] => Title History ) ) ) [3] => Array ( [id] => 3 [name] => Events [children] => Array ( [4] => Array ( [linke_url] => [link_name] => Preview Next Event ) [5] => Array ( [linke_url] => [link_name] => Latest Event Results ) [6] => Array ( [linke_url] => [link_name] => Event Archives ) [7] => Array ( [linke_url] => [link_name] => Schedule An Event ) ) ) [4] => Array ( [id] => 4 [name] => Media [children] => Array ( [8] => Array ( [linke_url] => [link_name] => Photo Gallery ) ) ) [5] => Array ( [id] => 5 [name] => Social ) ) 

Answer 1

You have:

 'linke_url' => (empty($child->permalink)) ? $child->link_url : $child->permalink, 

I assume you meant 'link_url' and not 'linke_url' , so it looks like you are trying to do:

If $child->permalink empty, set 'link_url' to $child->link_url , but if $child->permalink not empty, set 'link_url' to $child->permalink .

I would recommend using the shortened version of the ternary operator ?: , which is the form: $a = $b ?: $c , which matches if $b is evaluated as true , i.e. if $b has any value, $a = $b , otherwise $a = $c . For you:

 'link_url' => $child->permalink ?: $child->link_url 

If $child->permalink has a value that will be used, otherwise the value of $child->link_url will be used. Good luck
