Hello,
being new to codeigniter (and not feeling comfortable around OOP & MVC just yet), I struggling with a particular page element - main menu driven from a db table.
The db table is in attachment.
Here is what I wish to achieve:
1. read and return all items from table that have parent_id = 0 (or just all items and filter the array later)
2. check if there are any records in table where parent_id=id of current record
3. if there are none render in view as <li> element, if there are some render in view as <li class="dropdown"> element with css class
4. if subitems found read all that records from db that has a parent_id=id and render
pseudocode would be something like that:
Code:
$q_parent=db->query(SELECT * FROM tbl_menus WHERE parent_id=0);
$r_parent=db->records_array($q_parent);
for each ($r_parent){
$check = $r_parent['id'];
$q_child=db->query(SELECT * FROM tbl_menus WHERE parent_id=$check);
if ($q_child->numrows = 0){
echo '<li>'.$r_parent['display_name'].'</li>'; //render list element
} else {
echo '<li class="dropdown">'.$r1['display_name'].'<ul>'; //reder list element & open internal <ul>
$r_child=db->records_array($q_child);
for each ($r_child){
echo '<li>'.$r_child['display_name'].'</li>'; //render internal list element
}
echo '</ul></li>'; // close internal <ul> and dropown <li>
}
so far, using CI tutorials I am able to list the parent elements, bu nothing else
