<?php
$url = explode('/',$_SERVER['REQUEST_URI']);
$dir = $url[1] ? $url[1] : 'home';
?>
<body id="<?php echo $dir ?>">This would turn http://domain.tld/blog/home into “blog” (the second level of the URL structure). If at the root, it will return “home”.
Here is an alternate method:
<?php
$page = $_SERVER['REQUEST_URI'];
$page = str_replace("/","",$page);
$page = str_replace(".php","",$page);
$page = str_replace("?s=","",$page);
$page = $page ? $page : 'index'
?>This would turn http://domain.tld/blog/home into “domaintldbloghome”, which is far more specific. It also will remove “.php” file extensions and the default WordPress search parameter.
More Secure Method
function curr_virtdir($echo=true){
$url = explode('/',$_SERVER['REQUEST_URI']);
$dir = $url[1] ? $url[1] : 'home'; // defaults to this if in the root
$dir = htmlentities(trim(strip_tags($dir))); // prevent injection into the DOM through this function
if ($echo) echo $dir;
return echo $dir; // ie. curr_virtdir(false)
}
function get_curr_virtdir(){
curr_virtdir(false);
}Returns the “middle” directory value:
On https://css-tricks.com it would return “home”
On https://css-tricks.com/snippets it would return “snippets”
On https://css-tricks.com/forums/viewforum.php?f=6 it would return “forums”
The strip_tags() and htmlentities() functions prevent malicious code from being insterted into the URL and ran, e.g.
<body id="foo"><script>alert("Booo");</script>Usage for IDing the body:
<body id="<?php curr_virtdir(); ?>">Other usage:
<?php
if ( get_curr_virtdir() == "store" ){
echo "Welcome to our awesome store !";
} elseif ( get_curr_virtdir() == "home" ){
echo "Welcome home :-)";
} else {
echo "Welcome on some other page";
}
?>
Hmm, I used simplier code, without throught on security. I should reconsider this.
This was very helpful. Im using the alternate method (second one from the top). How would I keep the id selector to the first two directories. Say I have: domain.com/products/ramps/singlefoldramps.html
Would return id=”productsramps” and not use the third dir in the id tag?
I tend to use the . This also gives a lot of usefull information, similar to theese examples:
http://codex.wordpress.org/Template_Tags/body_class
Getting a syntax error on line6 of the secure version:
return echo $dir; // ie. curr_virtdir(false)
Any ideas?
Removed the “echo” – seems to have sorted it.
function curr_virtdir($echo=true){
$url = explode(‘/’,$_SERVER[‘REQUEST_URI’]);
$dir = $url[1] ? $url[1] : ‘home’; // defaults to this if in the root
$dir = htmlentities(trim(strip_tags($dir))); // prevent injection into the DOM through this function
if ($echo) echo $dir;
return $dir;
None of this tips works for me, can you help me guys?
My problem is, I have a site with two subdirectorys, I wanna output
example.com/dir1/dir2
example.com/dir1/dir2/dir3
The second and third directories always change. How can the ID be just the second directory (dir2)?
Thank you in advance!
Any way to get rid of the .php from the body id?
