Well, your basic logic is:

if ( they have a session )
{
   //output the menu
}
else
{
  //output the other menu

Hello once again, 

I have take my time to think on this for a while.

And I end up on the W3C recommendations about URIs: 
In a phrase: Keep it semantic, lifetime, and short.


Several questions arise at this moment:
I was having a url like this:
http://www.mysite.com/c_mycontroller/method/1/3/4/54

Where the numbers where Id's of categories or products. Well... 
this could be as far as we can get from the W3C recommendations. :s

So, let's say I short those urls to names, and I remove/hide(?)
from the URL the controller and method information's. 
We could end up on something like this:

http://www.mysite.com/categoryname/subcategoryname/subsubcategoryname/productname/

It's more semantic. But what if we have, 4 subcategories for example? This 
could get quite long. 


A possible solution to this, is to have something like this:
http://www.mysite.com/categoryname/subcategoryname/productname

In a way that we always get no more than 3 URI segments.
So, if the user navigates to a sub sub sub sub level on the hierarchy, the 
address could be:

http://www.mysite.com/categoryname/subsubsubsubcategoryname/productname




1) What are your thoughts on this? Should I follow this track on your opinions?


2) In order to be semantic, I intend to pass through the URI segments, NOT the 
Category id's but the Category names.
This will bring two issues (at least):
2.1) - I need to query the database, not by ID but by Name. (I'm not sure if 
they always be unique, I'm not sure if I will have a performance issue). As a 
note: This is a VERY little website. Nothing too fancy. 


2.2) I will grab the categories name from the database, and build the URL with 
those names, however, some category names will have INVALID chars, like á, ç, 
spaces... etc... What would be the best way of doing this? Having a new column 
on the database categories table with a "slug" field? Or, grab the category 
name, and prepare that name to be "url friendy" using a function for that? If 
it's possible to answer, where on a MVC structure would this function be?



Regards,
Márcio

Thanks a lot! Really.
I will now start coding based on all this information and see what I will get.

I'm sure that the designer will kill me later, by telling me... couldn't we

Think of it a bit like an online shop selling operating systems:

1) All the main OS's you sell are on the front page - Linux, MacOS &
Windows
2) User clicks on Linux, and is taken to the url /products/linux and
they are shown all the Linux OS's on offer (Fedora, SuSe, Ubuntu,
Knoppix, etc)
3) User clicks on Fedora and is taken to the URL /products/linux/fedora
and they are shown all the versions of Fedora up to 11
4) etc

The URL belies what section you are on, which makes it easy for the user
to remember, and easy for you to extract information from to know
exactly where the user is. Obviously in the above URLs I'm assuming
mod_rewrite is being used.

Ok. 

>so you only need to retrieve those that the user is interested in, which is 
>shown by what they click on.

The relation between click and the display of the corresponded array child 
elements, without using js, is the hardest to understand:
 
The user will click on a link / the URL will change / the new page will be 
loaded to the user / the information displayed on that page should be related 
with the element clicked on the first step. 

So, the next page, should know what we have clicked before, in order to display 
the information accordingly. 
One of the ways that this can be done, is by passing params over the URL. The 
URL param will tell us what element have we clicked, so it should be based on 
URL. Once we have that, we need to ask: as that value passed on the url a 
correspondent array element that contains children? If so, display them. 



(I realize my incapacity of talking technically, by referring to "pages" and 
other odd entities. I'm sorry for that).

Does the above makes any sense?

Thanks a lot,

That sounds about right yeah. You could also get a little bit clever and
only retrieve the rows from your db that will go to make the array
elements you'll need. It doesn't make sense to retrieve a full product
list each time someone visits the page, so you only need to retrieve
those that the user is interested in, which is shown by what they click
on.

Exactly.

Ok...

So the focus should not be on the click events, but on the URL changes.
 
Since it will be based on URL changes and not, on click/hover events, I can 
rely this navigation system entirely on php. Right?

If this is correct, the only think I need then, is to create a condition, to 
show/hide ul/li items based on:

a) the url changes.

OR

b) the existence or non-existence of child array elements that needs to be 
verified each time the user navigates to a page.



Is this correct?

I think the term drop-menu is bad in this case, as essentially what you
are saying is:

1) user is presented with the basic navigation menu
2) user clicks an item and page navigates somewhere else
3) because of the item user clicked in 2) display some extra menu items

That's not a menu, it's just a navigation bar that changes slightly
depending on where you are in the site...

[MEM]

Thanks a lot for your replies. 

Let's see if I understand, if not, please, let me know, I'm not that proficient 
in English. 
Second try, in order to accomplish this, I have to:


1) Generate the multidimensional array from query.

2) Generate the ul / li menu (echo + foreach) displaying all child elements as 
well.

3) Apply the anchor to the list items.
 
 3.1) Each anchor on this list should point to a new URL (I don't care if the 
page refreshes on this case).

4) Print all this on a nice way to the browser. (unobtrusive)

5) Apply js to:
 5.1) HIDE the elements that need to be hidden. 
 5.2) SHOW what needs to be displayed.


I don't want to have any onHover effect. The submenus will not appear on a 
onhover effect. 
They should appear when the user either clicks on a parent menu item, or 
navigates to a specific URL. 

Should this make me change this workflow somehow? 



Please have patience... :s

Thanks again,
Márcio

The JS part isn't for clicking at all.  Rather, it is for hovering.

Since IE doesn't have hover on any element besides the anchor, it is used to
mimic hovering in IE.

Use the following example to add the hover ability to your app.

Remember, JS is only used to create the ability for IE to hover over elements :)

NO!!!  don't do the following!

Now to satisfy the people that are going to ask the inevitable question "What if
JS is turned off??"

Show everything by default. Then, using JS, hide all that should be hidden and
go from their.

In that case, what you need to do is navigate to a new URL each time, as
there is no way you can change the URL at all. The only way to change it
without reloading is to alter the #anchor part of the URL, but that is
not too flexible.

RE: [PHP] dynamic menu with show hide capabilities - understanding possible workflow

[MEM]

Thank you all.
 
Ok. Please stay with me, cause I still have some doubts. 
Not only do I need to display the subitems on click but also, when the user 
clicks on one menu item, I need to change the URI as well.
Why? Because, each time the user clicks on a menu item (whateaver that item as 
childs or not), I want to display a list of products related to the clicked 
item.
 
So, I was trying to avoid js, because, I don’t know that much about js. 
However, I’d like to do it properly, so, the only way I was allowing the use of 
js, was by do not disabling the back button functionality and by allowing a add 
to favorites option as well, allowing the URI changing… O.o
 
Anyway, let’s face it: 
Js is my only option, could this be a nice workflow, for an unobtrusive 
solution?
 
 
1)  Generate the multidimensional array from query.
2)  Generate the ul / li menu (echo + foreach) displaying all child 
elements as well.
3)  Apply the anchor to the list items.
4)  Apply some js to that ul / li that: 
4.1) will be responsible for show/hide elements.
4.2) Will be responsible to show/hide elements only when some DOM node(?) as 
children.
4.3) Change the URI on click, so that some information can be showed based on 
uri segment. 
 
Can I have your help to fill the blanks here, or, if there are to many, just an 
orientation reference, in order to get started…
 
 
 
Thanks a lot once again,
Márcio

Everything there is feasible without Javascript except for the clicking part, 
which is pretty essential to what you want. Pure CSS-only menus are still 
unavailable because of IE, so using some Javascript is your only option really.

Is there a particular reason you are shying away from Javascript in this case? 
There are ways you can construct drop-down menus in a way that if Javascript is 
unavailable, then they fall back to becoming a bog-standard navigation bar.

Also, before anyone mentions them,  lists are not the same thing as a 
drop-down menu, and navigating to different parts of a document upon changing 
the selected option is actually breaking their default behavior, and can become 
confusing to people who expect them to work as select lists.

[PHP] dynamic menu with show hide capabilities - understanding possible workflow

Hello all,

I'm on my way to build my first dynamic menu using php.
However, each time I say this, people start jumping at me crying out loud:
"Jquery" .
I don't need js for this. Really. (At least, this is what I believe).

So I was wondering if It's possible to accomplish it, by using css and php
only.


If so, I'm wondering if something like this it's a good way for doing this:

1)
Generate a multidimensional array from database table containing categories
and subcategories.

2)
Create a css file with two classes one that shows, another that hides.

3)
Grab that array and: 
 3.1) print it recursively (no idea how to accomplish this)
 3.2) print it with some sort of class="showThis" inside the generated html
element.
 3.3) make a conditional somewhere (I really don't know where, and this may

elements, only when we click the parent element.

And here resides my main doubt: Is the point 3.3 feasible without the use of

The following will build a two-level menu as an unordered list, with the
second level appearing if its parent is selected. The variable "$gpid" is
grandparent id for a third level, which is not displayed in this menu. Some
checks are done in order to display a menu item differently if it is the
current page or an ancestor of the current page. (In the design I took this
example from, third level menus are shown in a different place.)

// build menu array
$menu_sql = "SELECT id, parentid, menuname, FROM pages";
$menu_result = mysql_query($menu_sql);
if (mysql_num_rows($menu_result) > 0) {
while ($menu_row = mysql_fetch_array($menu_result)) {
$menu_array[] = array($menu_row["id"], $menu_row["parentid"],
$menu_row["menuname"]);
}
}

// home id is 10
$id = isset($_GET["id"]) ? $_GET["id"] : 10;
$pid = isset($_GET["pid"]) ? $_GET["pid"] : 0;
$gpid = isset($_GET["gpid"]) ? $_GET["gpid"] : "";

// display menu
echo("");
foreach ($menu_array as $menu) {
// if the parent id is 0, menu item is main level
if ($menu[1] == "0") {
if ($menu[0] == $id || $menu[0] == $pid || $menu[0] == $gpid) {
echo("" . $menu[2] . "");
foreach ($menu_array as $menu2) {
if ($menu2[1] == $menu[0]) {
$subcount[] = $menu2[1];
}
}
if (count($subcount) > 0) {
echo("");
foreach ($menu_array as $menu3) {
if ($menu3[1] == $menu[0]) {
if ($menu3[0] == $id || $menu3[0] ==  $pid) {
echo("" .
$menu3[2] . "");
} else {
echo("" . $menu3[2] . "");
}
}
}
echo("");
}
echo("");
} else {
echo("" . $menu[2] . "");
}
}
}
echo("\n");

Re: [PHP] Dynamic menu not passing value to PHP?

[Dennis Martin Ong]

Got it sorted out now

>>This will select all the items if either $sltCat or $txtSearch is empty.

>>Janet

'%$txtSearch%' would always evaulate as '%%' in Mysql when the txtSearch
field is empty thus resulting in Mysql selecting everything in the database
making the the "category='$sltCat'" redundant...

I've rewritten it as:

if(empty($txtSearch)){
 $query_rsCat= "SELECT * FROM inventory WHERE category='$sltCat'";
}
else {
 $query_rsCat="SELECT * FROM inventory WHERE item_name LIKE '%$txtSearch%'";
}

to circumvent this and it worked..

Thanks Janet for pointing this out...and thanks all for the help

[PHP] Dynamic menu not passing value to PHP?

[Dennis Martin Ong]

Hi,

I'm trying to create a page where a user can choose to view products by
category by selecting a drop down menu or he can choose to do a search
against the item name. The script seems to work but I'm puzzled cos the
mysql query seems to be querying all the category while it is suppose to
match it via the selected option value from the dynamic menu. Is there
something I've missed out cos it seems like the $sltCat which is suppose to
pass the selected option value when the form is submitted is not passing the
correct value, resulting in the mysql query throwing out all the info when
it is supposed to only throw info when category match $sltCat..

Thanks in advance for the help

Re: [PHP] Dynamic menu from DB

[Marek Kilimajer]

I don't know about the flash part, but submenus are simple. Your menu 
items table needs a "parent" column, where the id of the parent menu 
item, but for top level menus (Flash static menu) it will be 0. Then 
first select all menu items with parent=0 and as you loop throught the 
result result, recursively get all child elements.
This function will get you started:

get_childs($menu_id) {
   $resp=array();
   $res=mysql_query("SELECT * FROM menu_items WHERE 
menu_parent_id='$menu_id'");
   if(mysql_num_rows($res)) {
   for($i=0;$tmp=mysql_fetch_array($res); $i++) {
   $resp[$i]['menu']=$tmp; // ['menu'] will contain info about 
particular menu item
   $resp[$i]['childs']=get_childs($tmp['menu_id']); // ['menu'] 
will contain all childs of this menu items, each child will again 
contain ['menu'] and ['childs'] etc.
   }
   }
   return $resp;
}

$menu_tree = get_childs(0);

echo '';
print_r($menu_tree);
echo '';

Re: [PHP] dynamic menu possible?

[Nikola Veber]

Whell, you could use that php script for getting file names and put links toward 
those files in a layer, which can be controled with java. If you are not a java 
expert, 
you can do it with macromedia dreamweaver + extensions. I don't know java, but I 
made a layer based site at http://www.okspartak.f2s.com/moj/
The best thing is that extensions are free ! If you are not sure in the number of 
files, you can use those ext. to make a scrollable meny, which can be a very 
attractive detail.

Cheers
Nikola

This is script for writing all files located in a folder:

$folder = "c:/borland/";
$dir = opendir($folder);
while ($file = readdir($dir)) {
 echo $file."";
}

[PHP] dynamic menu possible?

[LRW]

Hi all.
I was wondering if a situation I'll describe below is possible. If it is,
I'm hoping someone could point me to the topics I would need to study to
learn how to do it. I hate to say that right now I don't have the time to
read the Manual or any books cover-to-cover to figure it out...but I do want
to learn how to do things on my own. So if someone could just tell me what
the items I'd need to study are called, I'd really appreciate it.

What I want to do is have a drop-down menu where the options are files
located in a folder on the server that changes as items are added to or
removed. Then the user can select an item from the menu, submit, and that
page will load.
Did that make sense?
So I have 1.htm and 2.htm and 3.htm in a folder. A selectable menu reads the
folder and lists those three files as options. The user can click on it and
submit and that page will load. And if I add 4.htm, the menu will add that
to the drop down on its own.

That that's not possible, how close can I get to something like that?
An example of something close to that I found on www.megatokyo.com . They
have a dropdown menu where a user selects an item and gets sent to that
page. A URL from one attempts shows as
http://www.megatokyo.com/index.php?date=2001-09-04 . How is that done?

Again, if I could just be pointed to the related PHP concepts I'll take it
from there.
Thanks!
