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

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
be related with the recursion doubt), in order to display the children
elements, only when we click the parent element.
And here resides my main doubt: Is the point 3.3 feasible without the use of
js?
I just need some directions please,
Regards,
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, <select> 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.

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.

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 :)

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.

I've always gone the route of having the drop-downs just accompany a
standard, regular, functioning navigation bar. That way, if someone has
Javascript turned off, they are still able to use a standard, regular,
functioning navigation bar.

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

Any pointers in the right direction would so very much appreciated.

Try instantiating a Memcached instance, not a Memcache instance.
They're two different PECL extensions!

Hi
That just auto-instantiates an empty object?
> cat memcached.php
<?php
$memcache = new Memcached;
print_r($memcache);
?>
> php memcached.php
Memcached Object
(
)
I have used the $m=new Memcache; syntax on another server, which works fine.
Or have I mixed up my libraries somehow?

They're actually two different classes from two different PECL
extensions. Memcached is the newer (imo better) extension written by
Andrei (at digg) to use libmemcached. Memcache is the older, entirely
custom (no external deps) PECL extension that's been around forever.
So, I'm guessing you have Memcache on one machine and Memcached on
another. They have slightly different APIs, so I'd make sure you're
aware of which one you're using. :)

Thanks
Any chance you could show me the way?
This is how I installed the PECL extension:
> pecl download memcached
> tar zxf memcached-1.0.0.tgz
> cd memcached-1.0.0
> phpize
> ./configure
> make
> make install
Does that look like the right one? Did I miss something?

That'll install the Memcached extension, which is the one I'd usually
recommend and the one that I use. I don't see anythign wrong with
using that one or that way of installing it, but I was just saying
that the method names and parameters are different from the older
extension and to just be aware of that.
Old extension: http://us2.php.net/manual/en/book.memcache.php
New extension: http://us2.php.net/manual/en/book.memcached.php
The naming confusion is unnecessary but it exists so there's not
really too much you can do about it :P

I have the following xml with standard tags changed to [ and ] to
prevent mail clients from encoding it as html.
[?xml version="1.0"?]
[resultset errors="0" results="86"]
[result id="20080922133104871678" lastinspected="9/29/2009
0:00"]0.4[/result]
[result id="20080922133104871678" lastinspected="8/28/2009
0:00"]1.1[/result]
. . .
I am using the simplexml_load_string to read it in to an object and
execute the following code
$xml = simplexml_load_string($content);
foreach($xml as $Result){
print_r($Result);
foreach($Result->attributes() as $i => $v){
$$i = $v;
print "Attr: $i = '$v'\n";
}
}
that all works fine. Problem is I can't figure out how to get the
acutual value (0.4 and 1.1). I also don't know why I can't simply do
something like....
$id = $Result->attributes()->id;
the output of this looks like ....
SimpleXMLElement Object
(
[...@attributes] => Array
(
[id] => 20080922133104871678
[lastinspected] => 9/29/2009 0:00
)
[0] => 0.4
)
Attr: id = '20080922133104871678'
Attr: lastinspected = '9/29/2009 0:00'
SimpleXMLElement Object
(
[...@attributes] => Array
(
[id] => 20080922133104871678
[lastinspected] => 8/28/2009 0:00
)
[0] => 1.1
)
Attr: id = '20080922133104871678'
Attr: lastinspected = '8/28/2009 0:00'
How do I read the [0] value? $Result[0] gives me nothing.

Hi all!
This is my first mail, I hope I will use this mailing list in the correct
mode.
One of main advantages of SQL in the concorrent access of many script to the
same database.
I would like improve similar functions to the SimpleXML module.
In particular, I want modify the simplexml_load_file() function adding the
interaction with the flock() function.
What do you think about?

This works if you know the name of the class. What I'm looking for is a way to
get one of the sub classes and initialize it dynamically.

You may be able solve this with a simple class_exists() (pseudo-code ahead):
if(class_exists($var)) {
$class = new $var;
} else {
$class = new FourOhFour;
}

I'm confused. If you don't know the name of the child class, how are
you going to know which one to instantiate? Are you going to pick one
at random?
What you're trying to do can probably be accomplished, but I can't
shake the feeling we're trying to solve the wrong problem here.

This script only works for loaded classes .
If your script has autoloader then there is no way to know the declared
classes before you declare them.
error_reporting( E_ALL | E_STRICT );
Class Foo {}
Class Bar extends Foo {}
Class Baz extends Foo {}
Class Beer extends Bar {}
Class Pier extends Bar {}
function get_subclasses($class)
{
$sub = array();
foreach(get_declared_classes() as $name )
{
$rClass = new ReflectionClass($name);
if( $rClass->isSubclassOf( $class ))
{
$sub[] = $name;
}
}
return $sub;
}
print_r( get_subclasses( 'Foo' ));
print_r( get_subclasses( 'Bar' ));

Just having FUN, do not take me serious : )
function getInstanceRandom()
{
$classes = get_declared_classes();
$index = array_rand( $classes );
return new $classes[ $index ]();
}
$obj = getInstanceRandom();
echo get_class( $obj );
This is way you NEVER know which class you will instantiate!

Hi all. I'm not sure if this is really a PHP question or specific to XAMPP,
or windows in general...
I have XAMPP including PHP 4.29 running on a Vista machine.
When I use a form to upload a file, using $_FILES['uploadedfile']['name']
and move_uploaded-file($_FILES['uploadedfile']['name'], $targetpath) strange
effects happen.
The file is uploaded to the target directory just as it should.
But when I access this directory as a network share on a different machine,
the file is not visible.
When I go to delete the file, or the entire uploads folder, the file is not
deleted, nor the folder. If the folder contains anything I put there
manually (ie. not uploaded as above) that is deleted, but the uploaded
content remains.
This reminds me a bit of "symbolic links" behaviour but I'm really stumped
if that's the case.
Any ideas?

This sounds more like a windows permissions problem than PHP or XAMPP
related. Make sure the user that is connecting to the network share
has rights to view files on the windows box. It sounds like the user
that is running XAMPP has full control (or at least read/write/delete)
to that directory, but the user connecting to the network share
doesn't.

Yeah, definitely sounds like a permissions issue.
I'm not much of a windows admin, but this looks like it might help:
