Custom Page Title Shortcode within another Shortcode

Question

I use this function to obtain the title of post page in the content area:

function myshortcode_title( ){
return get_the_title();
}
add_shortcode( 'page_title', 'myshortcode_title' );

So, I have a plugin that when I use this shortcode below it read the text beetween the shortcode:

[responsivevoice voice="UK English Male"] Wonderful World [/responsivevoice]

So, what I'm doing and it's my question also is how can I put the "page title shortcode" within responsivevoice shortcode like this?

[responsivevoice voice="UK English Male"] [page_title] [/responsivevoice] 

(It should get the title of the post page, but it doesn't work).

Answer 1

Choose one of the following options, and add the code snippet after:

add_shortcode( 'page_title', 'myshortcode_title' );

Option #1: [responsivevoice2]

add_shortcode( 'responsivevoice2', 'responsivevoice2' );
function responsivevoice2( $atts = array(), $content = '' ) {
    if ( $content = do_shortcode( $content ) ) {
        return RV_add_bblisten( $atts, $content );
    }
    return '';
}

Sample usage:

[responsivevoice2 voice="UK English Male"] [page_title] [/responsivevoice2]

This Shortcode allows you to use the [page_title] or any other Shortcodes in the text to be spoken.

Option #2: [responsivevoice_page_title]

This Shortcode will always use the page title (or the title of the current post) as the text to be spoken. With this Shortcode, you don't need the [page_title] Shortcode anymore.

add_shortcode( 'responsivevoice_page_title', 'responsivevoice_page_title' );
function responsivevoice_page_title( $atts = array() ) {
    if ( $page_title = get_the_title() ) {
        return RV_add_bblisten( $atts, $page_title );
    }
    return '';
}

Sample usage:

[responsivevoice_page_title voice="UK English Male" /]
