Add Font-Select Drop Down to Visual Editor

Add the font-select menu to the 2nd row of buttons (revealed with the Kitchen Sink button)

If some items aren’t removed from the second row, the buttons won’t fit nicely on a 1024×768 screen.

See WordPress’s default buttons in wp_tiny_mce()

add_filter('mce_buttons_2', 'add_fontselect_row_2' );

function add_fontselect_row_2( $mce_buttons ) {
        find the keys of the buttons to be sacrificed
    $pastetext = array_search( 'pastetext', $mce_buttons );
    $pasteword = array_search( 'pasteword', $mce_buttons );
    $removeformat = array_search( 'removeformat', $mce_buttons );

    unset( $mce_buttons[ $pastetext ] );
    unset( $mce_buttons[ $pasteword ] );
    unset( $mce_buttons[ $removeformat ] );

        insert the new dropdown where the sacrificed buttons used to be
        alter as needed
    array_splice( $mce_buttons, $pastetext, 0, 'fontselect' );
    return $mce_buttons;

But if you’re adding the 3rd row, you’re probably clear (unless you have other plugins that are adding buttons).

add_filter('mce_buttons_3', 'add_fontselect_row_3' );

function add_fontselect_row_3( $mce_buttons ) {
    $mce_buttons[] = 'fontselect';
    return $mce_buttons;

Currently, any buttons added to the 3rd or 4th rows will always be visible (Kitchen Sink only shows/hides the 2nd row) – but a patch has been submitted to correct this, hopefully it’ll be committed.

However, if you’ll probably want to clean up the font options – remove fonts that you’ll never use (or should never be used).

add_filter('tiny_mce_before_init', 'restrict_font_choices' );
function restrict_font_choices( $initArray ) {
    $initArray['theme_advanced_fonts'] = 
        'Andale Mono=andale mono,times;'.
        //'Arial Black=arial black,avant garde;'.
        'Book Antiqua=book antiqua,palatino;'.
        //'Comic Sans MS=comic sans ms,sans-serif;'.
        'Courier New=courier new,courier;'.
        'Times New Roman=times new roman,times;'.
        'Trebuchet MS=trebuchet ms,geneva;'.
        //'Wingdings=wingdings,zapf dingbats'.
    return $initArray;
