如果页面无法回显自定义标题

Question

i have a posttype to which i have a page templates assigned using plugin custom posttype page template, so that my posts having img attachments in the posttype are displayed using a particular template. In my header.php i have code

if ( is_page_template ( 'page-book.php' ) )
                { $currenturl=$_SERVER['REQUEST_URI'];
                  $booktitle = str_replace("http://mybooks.com/books/", "", $currenturl);
                  $booktitle = str_replace("-", " ", $booktitle);
                  $booktitle = strtoupper($booktitle);
                  echo $booktitle;
                }

but it echoes the url of the post in the title instead of the custom echo

how do i get it to echo the custom title

Answer 1

This line $currenturl = $_SERVER['REQUEST_URI']; of your code only return string that is part of the URL.

For example, the given url http://mybooks.com/books/title it return /books/title and when you try to replace it with an empty string nothing is replace because str_replace function doesn't find a match.

For you to get the trailing part of the url, you can use basename

For example

echo basename($currenturl);

It will return the last part of the url and that is

title.
