When I am in page A (or one of it's children) I wish to show it's one level of
children like so:
Page A
Child 1
Child 2
etc...
Page B
When I am in page B (or one of it's children) I wish to show it's one level of
children like so:
Page A
Page B
Child 1
Child 2
etc...
Do you get the picture?
I have a db with link url, id, parent id and title
does any one know of a simple function or something to do this for one level?
I wrote the code below for a menu system like this on a recent project:
--
// declare class (s)elect (l)ist
class sl
{
var $query;
var $result;
var $row;
function set_query($new_value)
{
$this-query = $new_value;
}
}
// create object (c)ategory (s)elect (l)ist
$csl = new sl();
// create object (s)ubcategory (s)elect (l)ist
$ssl = new sl();
// set query for object csl to display main categories
$csl-set_query(SELECT ID, Name FROM Categories WHERE ParentID=0);
$csl-result = mysql_query($csl-query);
// display the menu
while ($csl-row = mysql_fetch_array($csl-result))
{
$ParentCatID=$csl-row[ID];
if ($csl-row[ID] == $MainCatID)
{
echo(p class=\menuselected\ .
a href=$PHP_SELF?MainCatID=$ParentCatID .
$csl-row[Name] . /a/p\n);
// set query for object (s)ubcategory (s)elect (l)ist
$ssl-set_query(SELECT ID, Name, ParentID FROM Categories .
WHERE ParentID=$MainCatID);
$ssl-result = mysql_query($ssl-query);
// display subcategories (submenu)
while ($ssl-row = mysql_fetch_array($ssl-result))
{
$ParentCatID = $ssl-row[ParentID];
$ChildCatID = $ssl-row[ID];
if ($ssl-row[ID] == $SubCatID)
{
echo(p class=\submenuselected\ .
a href=$PHP_SELF?MainCatID= .
$ParentCatIDSubCatID=$ChildCatID .
$ssl-row[Name] . /a/p\n);
}
else
{
echo(p class=\submenu\ .
a href=$PHP_SELF?MainCatID= .
$ParentCatIDSubCatID=$ChildCatID .
$ssl-row[Name] . /a/p\n);
}
}
}
// finish main category display
else
{
echo(p class=\menu\ .
a href=$PHP_SELF?MainCatID=$ParentCatID .
$csl-row[Name] . /a/p\n);
}
}

Main menu categories have a ParentID assignment of 0 in the db. A select is
done of all ID Name in the Categories table where ParentID=0. The menu is
displayed with names linked to recalling the script and passing the variable
$MainCatID -- the ID of the category. When the script is called with
$MainCatID set (when a main menu category is selected), the menu name with
ID matching $MainCatID is assigned a style class to distinguish visually
that it's selected. Also at this point another selection is done from
Categories where ParentID=$MainCatID, thus creating the list of
subcategories for the selected main category. The subcategories are also
displayed with links back to the script passing the variable $MainCatID
again plus the variable $SubCatID. When the script is called with $SubCatID
set, the submenu name with ID equal to $SubCatID is also class-styled to
indicate the selection.
The main page display (in this case for a products catalog) is generated by
other selection queries based on $MainCatID and $SubCatID.

RE: [PHP] Nested Menu Help
I found a way of doing this in order to show the home button when
browsing the site, but not when seeing the home page. What I do, is to
set two menus like this:
If ($browse == yes)
{
a href=index.phphome/a
}
a href=page1.php?browse=yespage 1/a
a href=page2.php?browse=yes page 2/a
a href=page3.php?browse=yes page 3/a
Notice how the links to other pages have the browse=yes set. You could
do something like this by building two menus (A and B) so PHP will read
something like browse=a or browse=b and fetch the right buttons from the
DB using different queries.
I know there must be an easier way, but so far, this is what I came with
which suites my needs very well.
