is it possible to customize shortcode in theme -or- make new shortcode combining two shortcodes

Question

I'm sorry if i asking stupid question because as i not code /php expert ?

I usering gravityview to filter and display gravity from values.

[gravityview id="111" search_field="11" search_value="xyzes"]

Now I want to change search_value dynamically AS "current logged in user"

So I trying making new SHORTCODE but not good working or not good idea

add_shortcode( 'customcode' , 'wp_get_current_user_func' );

function wp_get_current_user_func( $atts ) { 
    $current_user = wp_get_current_user();

    return do_shortcode('[gravityview id="1111" search_field="16" search_value="$current_user = wp_get_current_user();"]');
}

MY Request please suggest me what right code or is there any way in backend I able to do as altering theme file?

Thank you so much in advance

You were close enough. Here is how you should do it:

add_shortcode( 'customcode' , 'wp_get_current_user_func' );

function wp_get_current_user_func( $atts ) { 
$current_user = wp_get_current_user();
$user_login = $current_user->user_login;
//return do_shortcode('[gravityview id="1111" search_field="16" search_value=".$user_login."]');
$shortcode = sprintf(
'[gravityview id="%1$s" search_field="%2$s" search_value="%3$s"]',
"1111",
"16",
$user_login
);
echo do_shortcode( $shortcode );
}

You were missing to retrieve $current_user->user_login from function wp_get_current_user()

$user_login = $current_user->user_login;

You can also print out the other values as in this example:

<?php
    $current_user = wp_get_current_user();
    /**
     * @example Safe usage: $current_user = wp_get_current_user();
     * if ( !($current_user instanceof WP_User) )
     *     return;
     */
    echo 'Username: ' . $current_user->user_login . '<br />';
    echo 'User email: ' . $current_user->user_email . '<br />';
    echo 'User first name: ' . $current_user->user_firstname . '<br />';
    echo 'User last name: ' . $current_user->user_lastname . '<br />';
    echo 'User display name: ' . $current_user->display_name . '<br />';
    echo 'User ID: ' . $current_user->ID . '<br />';
?>
