plugin to hide selection of text from post from frontpage

Question

is there any plugin that will add new quicktag, says:

[hidetext]some text to hide[/hidetext]

and any text inside those tag is hidden from frontpage/archive/etc. It only shown on single post page.

Answer 1

add_shortcode( 'hidetext', 'my_hidetext_shortcode' );
function my_hidetext_shortcode( $atts, $content = '' ) {
    if( is_single() )
        return $content;
    else
        return;
}

Docs: add_shortcode(), is_single()

Solution is untested.

Answer 2

A slight modification on the function above. You'll want to use is_singular('post') instead, unless you also want to target other areas

add_shortcode( 'hidetext', 'rkv_hidetext_shortcode' );

function rkv_hidetext_shortcode( $atts, $content = null) {
    if( is_singular('post') )
        return $content;
    else
        return;
}

tested and works.
