Link issue

    Hello,

    I'm trying to create links on my website which depend on the folder you are in. Like for instance, if I'm at mysite/somepage.php the link would just be index.php and if I'm at mysite/anyfolder/somepage.php the link would be ../index.php.

    I know I can call the url like this:
    $url= $_SERVER['PHP_SELF'];

    But then ? It would be nice if you could take all the text in betwoon two slashes. Like this: let's say your url is mysite/folder/subfolder/page.php and you would be able to split this url into mysite, folder, subfolder and page.php.
    Is there a command to do this or a work around?

    Thx in advance,,

    Yes this is very easy to split a path into its folders or parts. You have to just use php explode function and you are done. In this case code will be.

    
$path="mysite/anyfolder/somepage.php";
$pathAry= explode("/",$path);
//Now above statement will remove slash from path and save each part of text
// in between as an array element like following
//$pathAry[0] contains "mysite"
//$pathAry[1] contains "anyfolder"
//and so on.
    PHP:
    You can use this function for exploding on base of more than one character. Following link explains it all

    Hope it is helpful. :)

    Since it's still a forum I'm gonna post my code here to help other people,, Following code is a php file which is being included in all my other pages, I think it's an easy way to manage all your links at once. I use this like a 'top' on my page with a few quick links, news items..

    <body>
<?
	function setPath($url){
		$path = $_SERVER['PHP_SELF'];
		$seperated = explode("/",$path);
		$size = count($seperated);
		
		$url_up = "../" . $url;
		$present = false;
						
		for($i=0; $i<$size; $i++){
			if(($sep[$i] == "poll") || ($sep[$i] == "admin")){
				$present = true;
				break;
			}
			else{
				$present = false;
			}
		}
		if($present == true){
			echo($url_up);
		}
		else{
			echo($url);
		}
	}
?>
	<ul> 
		<li><a href="<? setPath("cg_poll.php#poll_2"); ?>" target="_self" class="item_top">» Poll, Party</a></li>
		<li><a href="<? setPath("cg_poll.php");?>" target="_self" class="item_top">» Test poll added</a></li>
		<li><a href="<? setPath("index.php#news?");?>" target="_self" class="item_top">» Site online</a></li>
	</ul>
</body>
    Code (markup):
    How it works:
    *The variable $url_up simply takes the path up one folder by adding "../" to the url. You can easily change this variable - let's say to variable $url_down - so it takes you one folder down by adding "foldername/" to it. If you do that, echo($url_up) needs to be echo($url) and echo($url) needs to be echo($url_down).
    *Read previous posts in this topic, then you'll understand that if(($sep[$i] == "poll") || ($sep[$i] == "admin")) means I'm in the poll or admin folder on my site. So for people with other folders, change/add condition here.
    *In your actual html code (under href) the php function is being called.

    Hoop this makes sense,, :D
