Hello,
I would appreciate a lot If somebody can help me with the Tree View In Listbox solution:
(http://forums.yessoftware.com/posts.php?post_id=71501)
I placed the function list_categories() at the end of Common.php, then in the Open event of the page but I always get: page not found. I take out the function and the page is found. Is a page with a record form to create an article.
Please bear in mind that I am not an object oriented programmer. I was only testing if I can get the tree of the categories before I change my code to submit the selected category value.
Thanks a lot
joejac
Here is the code:
1.- in HTML the Label:
<tr class="Controls">
<th>Categorias</th>
<td>{my_tree_menu}</td>
</tr>
2.- this is my full file articulos_events.php
<?php
//BindEvents Method @1-AA8F8EEC
function BindEvents()
{
global $articulos;
$articulos->my_tree_menu->CCSEvents["BeforeShow"] = "articulos_my_tree_menu_BeforeShow";
}
//End BindEvents Method
//articulos_my_tree_menu_BeforeShow @31-9311207E
function articulos_my_tree_menu_BeforeShow(& $sender)
{
$articulos_my_tree_menu_BeforeShow = true;
$Component = & $sender;
$Container = & CCGetParentContainer($sender);
global $articulos; //Compatibility
//End articulos_my_tree_menu_BeforeShow
//Custom Code @32-2A29BDB7
// -------------------------
//-- BEGIN Menu tree for articulos.php
function list_categories() {
$names=array();
$cats=array();
global $dyn_menu;
$dyn_menu = "";
$db = new clsDBConnection1();
//- $db = new clsDBcms();
$dyn_menu .="<select name=\"category\">";
// adjust the query below with the proper field names and table name
// DON'T change the 'id', 'name' and 'parent' aliases in the query!
$SQL = "SELECT categoria_no AS id, categoria_nombre AS name, parent_categoria_no AS parent FROM categorias";
$result = $db->query($SQL);
//while ($row = mysql_fetch_assoc($result))
while ($db->next_record())
{
//$names[$row['id']] = $row['name'];
//$cats[$row['id']] = $row['parent'];
$names[$db->f("id")] = $db->f("name");
$cats[$db->f("id")] = $db->f("parent");
}
display_options(hierarchize($cats, 0), $names);
$db->close();
$dyn_menu .="</select>";
return $dyn_menu;
}
function hierarchize(&$cats, $parent) {
$subs = array_keys($cats, $parent);
$tree = array();
foreach ($subs as $sub) {
$tree[$sub] = hierarchize($cats, $sub);
}
return count($tree) ? $tree : $parent;
}
function display_options(&$tree, &$names, $nest = 0) {
global $dyn_menu;
foreach ($tree as $key => $branch) {
$indent = $nest ? str_repeat('--', $nest) . '| ' : '';
$dyn_menu .="<option value=\"$key\">$indent{$names[$key]}</option>\n";
if (is_array($branch)) {
display_options($branch, $names, $nest + 1);
}
}
}
//-- END Menu tree for articulos.php
$articulos->my_tree_menu ->SetValue(list_categories() );
// -------------------------
//End Custom Code
//Close articulos_my_tree_menu_BeforeShow @31-52ED58BF
return $articulos_my_tree_menu_BeforeShow;
}
//End Close articulos_my_tree_menu_BeforeShow
?>
