Question

I am building a gallery in WordPress and I’m trying to grab a specific part of my URL to echo into the id of a div.

This is my URL:

http://www.url.com/gallery/truck-gallery-1

I want to isolate the id of the gallery which will always be a number(in this case its 1). Then I would like to have a way to print it somewhere, maybe in the form of a function.

Answer 1

You should better use $_SERVER['REQUEST_URI']. Since it is the last string in your URL, you can use the following function:

function getIdFromUrl($url) {
    return str_replace('/', '', array_pop(explode('-', $url)));
}

@Kristian ‘s solution will only return numbers from 0-9, but this function will return the id with any length given, as long as your ID is separated with a - sign and the last element.

So, when you call

 echo getIdFromUrl($_SERVER['REQUEST_URI']);

it will echo, in your case, 1.
