I have a simple table layout with items that are sortable by clicking on little up and down arrows at the end of the row. We've all seen them in cms's etc...
I am using datamapper with this application
here is my moveup function in the controller:
Code:
//menu item move up function
function moveup($menu_id, $item_id){
$current = new Menu_item();
$current->where('id', $item_id)->get();
$new = $current->order - 1;
$moveup = new Menu_item();
$moveup->where('menu_id', $menu_id);
$moveup->where('order', $new)->get();
$order = $moveup->order;
$moveup->order = $order + 1;
$movedown = new Menu_item();
$movedown->where('id', $item_id)->get();
$order2 = $movedown->order;
$movedown->order = $order2 - 1;
if($moveup->save() && $movedown->save()){
$this->session->set_flashdata('success', 'Menu Item Moved up successfully');
redirect('menu_manager/menu_items/'.$menu_id);
}
else{
$this->session->set_flashdata('errors', 'Error: Menu Item could not be moved!');
redirect('menu_manager/menu_items/'.$menu_id);
}
}
This is how Iv done it before using ordinary php
Code:
function moveup($id,&$db)
{
$current = $db->get_var("SELECT intOrder FROM tblMenuItems WHERE intItemID = ".$db->mysql_prep($id));
$new = $current - 1;
$sql = "UPDATE tblMenuItems SET intOrder = intOrder + 1 WHERE intOrder = $new AND intMenuID = ".$db->mysql_prep($_GET['_menuid']);
$db->query($sql);
$sql = "UPDATE tblMenuItems SET intOrder = intOrder - 1 WHERE intItemID = ".$db->mysql_prep($id);
$db->query($sql);
}
I have the reverse for movedown but surly there is a more efficient way of doing this with datamapper? I know I could use fancy jquery drag n drop ect but just trying to keep this simple.
