Preserved Topic: Current URL

Not sure where to go here...no luck figuring out what I need from the manual.

I have a header file, with simple text link navigation, which is inlcuded by all of my content pages.

I want to determine which file is calling the inlcude (what the current page is) and adjust how the navigation is output accordingly.

How do I determine which file is currently being viewed?

Well, you didn't say which language, so I'm going to assume PHP. In PHP, you could check what $PHP_SELF is. That should be the document calling the URLs if you're using a page that calls various files. If you have something more complex like pages that call pages that call other pages, I'm not sure.

But $PHP_SELF should be the document in the URI

heh. Yes, PHP...always forget to specify that here.

I had actually searched the function lisst for 'php_self' as I seemed to remember seeing that...but hadn't thought to expand the search beyond the functions.

Thanks Pugzly =)

Well, in case it's helpful to anyone else, or in case anyone can see that i'm doing something either stupid or inefficient, here's what I did all in all -

<?php



$links = array

	(

	'/index.php' => ("Home"),	

	'/sketches.php' => ("Sketches"),

	'/links.php' => ("Links")

	);

	

$cur_page = $PHP_SELF;

$num_links = sizeof($links);

$sep = "&nbsp;&nbsp;-&nbsp;&nbsp;";



foreach ($links as $path => $text)

	{

	

	if ($cur_page != $path)

		{

		$a_open = "<a href=\"$path\">";

		$a_close = "</a>";

		}	



	else

		{		

		$a_open = "<span class=\"on\">";

		$a_close = "</span>";

		}

		

	echo "$a_open$text$a_close$sep";

	}

	

?>

Still being new to all this, it took a bit of thinking on my part to get this done. =)
It's rather simple, of course, but seems easy to expand upon for more complex structures.

Thanks again.

If you're on IIS, you won't have the luxury of $PHP_SELF. I wrote a workaround for this; anyone who needs it, give me an email.

Why is that? I locally run IIS and use $PHP_SELF



Elias,

Funny... not only have I run into a lack of $PHP_SELF in IIS, but I've seen numerous write-ups on the topic. Let me rephrase -- if you use IIS, you might not have $PHP_SELF.

hey DL 2 quick tips.

First you don't really need to set $PHP_SELF to $curr_path just use $PHP_SELF on it's own or if you use something like

$curr_path = basename($PHP_SELF);

you'll get just "index.php" etc without the slashes and just the file name if you are not in your home directory.
ie basename("/path/to/whatever.html")

returns just "whatever.html"

Which means you can get rid of some slashes which brings me to my second point. Your array is kinda backwards, it's not really a big issue as long as it works but genrally the way you want hashes (you're making a hash here) like so

$hash['key'] = "VALUE where this is all your wierd data";

you have it like :

$hash['VALUE where this is all your wierd data'] = 'key'

just a little backwards.



.:[ Never resist a perfect moment ]:.

Bit - the $cur_page I had initially imagined broader plans for, and had thought I would have to alter the info from the $PHP_SELF before using it...never went back to remove it.

The array itself had also started out larger and more complex, so it didn't seem so strange then. It looks kinda funny now though

Thanks for the tips - I'll switch those around.

Urk, I must have been half asleep when I wrote those earlier messages... what I meant was that $DOCUMENT_ROOT isn't found on IIS. $PHP_SELF works just fine.

DL-44,

the reason why you cannot find $PHP_SELF anyway in the function is, is because it's not a function. It is a predefined constant. hope that helps.

you should also check out getenv().
This functions get's enviroment variables, which not only
contain the url to the current script, but it's path and it's parameters (-> the stuff behind the ? in the url) as well.

so long,

(edit: typo in the only place that counts. the function name.)
