Hierarchal Menu in PHP from Array -


alright, it's hump day, , brain's shot.

can tell me i'm doing wrong here, i'm trying build navigation list (hierarchal)

here's array:

array ( [0] => array     (         [contentid] => 1         [parentid] => 0         [linkalias] =>      )  [1] => array     (         [contentid] => 2         [parentid] => 0         [linkalias] => inner     )  [2] => array     (         [contentid] => 3         [parentid] => 2         [linkalias] => inner-2     )  [3] => array     (         [contentid] => 4         [parentid] => 3         [linkalias] => inner-21     )  )

and attempts @ recursive function:

    // parse out array displaying multi-level menu     private function parsemenu($menu, $parent = 0){         $ret .= '<ul>';         $ict = count($menu);           for($i=0; $i < $ict; ++$i){             if($menu[$i]['parentid'] == $parent){                                $ret .= '   <li>' . $menu[$i]['linkalias'];                 if($parent > 0){                     $ret .= parsemenu($menu, $menu[$i]['contentid']);                 }                 $ret .= '</li>';                             }         }         $ret .= '</ul>';         return $ret;     }

right now, returning:

<ul>     <li></li>     <li>inner</li> </ul>

it should showing

<ul>     <li></li><!-- yes intentional -->     <li>inner             <ul>                     <li>inner-2                             <ul>                                     <li>inner-21</li>                             </ul>                     </li>             </ul> </ul>

so.. doing wrong, , how can fix it?

make line ...

if($parent > 0){     $ret .= parsemenu($menu, $menu[$i]['contentid']); }

into ...

$ret .= $this->parsemenu($menu, $menu[$i]['contentid']);

you never calling function again because starting $parent = 0

$ret .= '</ul>'; if($ret == '<ul></ul>'){      return; } else {     return $ret; }

php - Calling a template part from a post -

i include iframe within post in wordpress. located inside content of post, meaning cannot in post template file, otherwise either before or after. i'd add facebook plugin within posts: <div id="socialwrap"><div class="fb-like" data-href="http://onlinearizonahomes.info" data-send="true" data-width="450" data-show-faces="true" data-font="arial"></div></div> i thinking of calling template part within post <?php get_template_part( 'social' ); ?> cannot use php within post without plugin (i'd avoid using plugin this). an alternative using javascript create html in post, seems unnecessary use of javascript. what best way add html within wordpress post? you can use shortcode. add functions.php function cudjex_fbshare( $atts, $content = null ) { global $post; $link = get_permalink($post->id); return '<div id="socialwrap...
