How Do I Set the Page Title Dynamically?

by

Is it possible to change the page title with code?

For example, let’s say the page’s name is “Book your Order”, but I want to change it to “Book Order #123”.

I Google’d a bit and looked here and didn’t see anything. Anyone know of a plugin or hack?

wp_title returns the page title but doesn’t allow setting the page title:

There is no documentation on it but you could always apply a filter to the_title like this:

add_filter('the_title','some_callback');
function some_callback($data){
    global $post;
    // where $data would be string(#) "current title"
    // Example:
    // (you would want to change $post->ID to however you are getting the book order #,
    // but you can see how it works this way with global $post;)
    return 'Book Order #' . $post->ID;
}
