Zrobilem tak, jednak nie działa:
foreach ($children[$parent] as $option){
if ($loop &&(( $parent > $root_id ))){
Cały kod funkcji przed zmianami:
while ($loop && ( ( $option = each($children[$parent]) ) || ( $parent > $root_id ) )) {
if ($option === false) {
$parent = array_pop($parent_stack);
// HTML for menu item containing childrens (close)
$html[] = str_repeat("\t", ( count($parent_stack) + 1 ) * 2) . '</ul>';
$html[] = str_repeat("\t", ( count($parent_stack) + 1 ) * 2 - 1) . '</li>';
} elseif (!empty($children[$option['value']['id']])) {
$tab = str_repeat("\t", ( count($parent_stack) + 1 ) * 2 - 1);
// HTML for menu item containing childrens (open)
$this->html[] = sprintf(
'%1$s<li><a href="%2$s">%3$s</a>',
$tab, // %1$s = tabulation
$option['value']['link'], // %2$s = link (URL)
$option['value']['title'] // %3$s = title
);
$this->html[] = $tab . "\t" . '<ul class="submenu">';
array_push($parent_stack, $option['value']['parent_id']);
$parent = $option['value']['id'];
} else
// HTML for menu item with no children (aka "leaf")
$this->html[] = sprintf(
'%1$s<li><a href="%2$s">%3$s</a></li>',
str_repeat("\t", ( count($parent_stack) + 1 ) * 2 - 1), // %1$s = tabulation
$option['value']['link'], // %2$s = link (URL)
$option['value']['title'] // %3$s = title
);
}
// HTML wrapper for the menu (close)
$this->html[] = '</ul>';
return implode("\r\n", $this->html);
}
}
