How to get a "node" value from URL using arg(0)?

Question

I have this problem in getting a value from URL.

First I've created an url alias for a certain articles.

In example, from this /node/899 the alias I've created it's /news/investments/899

Then when I use arg(0) which is to get the value of first parameter which is "news" I get a result "node". The url alias works.

Answer 1

You can get aliased path using drupal_get_path_alias API Function..

$alias_path = drupal_get_path_alias();
$alias_arguments =  explode('/', $alias_path);
print $alias_arguments[0];

Answer 2

As you are using url alias ,you wont be able to get it using arg(0),Because your actual url is http://sitename.com/node/899

You can access the 'news' using request_uri function like as follow

$url_parts = explode('/',request_uri());

You can get 'news' in $url_parts[1]

Hope this will work for you

Answer 3

with this code you'll get the alias of the node/1. Then you can take the part you need with explode function.

drupal_get_path_alias('node/1');

if you want to get the alias of the current path, just write

drupal_get_path_alias();
