I’ve been trying to transfer an html form, which I had working perfectly on a static html page, onto a WordPress page. WordPress insisted on adding multiple <br/> tags where I didn’t want them. Mutter.

Eventually, after much searching, I identified a parameter within wp-includes/formatting.php, which allows you to disable this irritating feature. If you open formatting.php and find the function wpautop you’ll see this:

function wpautop($pee, $br = 1)

Change this to:

function wpautop($pee, $br = 0)

Save the file and publish it back to your server and that’s it. Works fine in WP2.8.

Note: WP 2.8.3 overwrites formatting.php so this change needs redoing.
