I have created a function to make these all these values the same

Here it is:

function my_bp_signup_blog_url_value() {
echo my_bp_get_signup_blog_url_value();
echo my_bp_get_signup_blog_title_value();
echo my_bp_get_signup_username_value();
}
function my_bp_get_signup_blog_url_value() {
$value = '';
if ( isset( $_POST ) )
$value = $_POST;

return apply_filters( 'my_bp_get_signup_blog_url_value', $value );

}
function my_bp_get_signup_blog_title_value() {
$value;
if ( isset( $_POST ) )
$value = $_POST;

return apply_filters( 'my_bp_get_signup_blog_title_value', $value );
}
function my_bp_get_signup_username_value() {
$value;
if ( isset( $_POST ) )
$value = $_POST;

return apply_filters( 'my_bp_get_signup_username_value', $value );
}

It sets the values, but the required errors comes up. What is wrong with my function or what is a better way to do it.

thanks ahead of time
