I'm making a course plugin for a university in England. I'm looking to put some default placeholder text in the main post content area, on the admin side. Its the rich text editor I want it to go behind. I might just be typing the wrong words, but can't find it here... preferably a non js thing...

Basically something like 'Use this area to write an introduction to the course...'.

You can change 'post' to which ever post type you want to apply the default content to.

add_filter( 'default_content', 'wpse57907_default_content', 10, 2 );
function wpse57907_default_content( $content, $post ) {
    if ( 'post' == $post->post_type )
        $content = 'Use this area to write an introduction to the course...';

    return $content;


I'm not sure you can add placeholder text to tinymce editors. The followng method will add a placeholder to the underlying textarea (you can view it on the 'html', soon to be 'text' tab):

function wpse57907_add_placeholder( $html ){
    $html = preg_replace('/<textarea/', '<textarea placeholder="my place holder text" ', $html);
    return $html;

But this does not appear on the visual editor (as I say, I'm not sure placeholders work with TinyMCE - if someone knows how, please comment.).

Hey Stephen, thanks for quick response that's almost exactly what I'm looking for except do you know any way to make it like placeholder text? So it will disappear as soon as they focus in the field? –  danbrown Jul 9 '12 at 15:35
I've updated my answer... –  Stephen Harris Jul 11 '12 at 19:39
TinyMCE is an iframe with regular HTML and contenteditable if I remember this correct. The only way to let text act like a HTML5 placeholder is some (probably fragile) JavaScript. –  toscho Jul 11 '12 at 19:50
Oh ok thanks, the first method does the job anyway, I'm probably being a bit OCD about it. Cheers for the answers :) –  danbrown Jul 13 '12 at 8:13
