How to get URL of current page displayed?
I want to add custom PHP code to ensure that whenever a page on my site loads in my browser, the URL of that page is echoed to the screen. I can use
echo get_permalink(), but that does not work on all pages. Some pages (e.g. my homepage) display several posts, and if I use
get_permalink() on these pages, the URL of the displayed page is not returned (I believe it returns the URL of the last post in the loop). For these pages, how can I return the URL?
Can I attach
get_permalink() to a particular hook that fires before the loop is executed? Or can I somehow break out of the loop, or reset it once it is complete?
