Hi,
\nThe learning curve continues!
\nI am trying to create a child function.php, I have looked at the Codex page and just need some clarification please.<\/p>\n

There are two changes I wish to make to my child theme, neither radical, more me being fussy and also to help me understand better how things work.<\/p>\n

I know how to delete the text I don’t want in the function.php file of the parent, however after an upgrade it obviously reverts back. I therefore want to create a child .php<\/p>\n

The parent .php looks like this;<\/p>\n

function pinboard_current_location() {\n\tglobal $pinboard_page_template;\n\tif ( ! ( is_home() && ! is_paged() ) && ! is_singular() || isset( $pinboard_page_template ) ) {\n\t\tif( is_author() )\n\t\t\t$archive = 'author';\n\t\telseif( is_category() || is_tag() ) {\n\t\t\t$archive = get_queried_object()->taxonomy;\n\t\t\t$archive = str_replace( 'post_', '', $archive );\n\t\t} else\n\t\t\t$archive = ''; ?>\n\t\t<hgroup id="current-location">\n\t\t\t<h6 class="prefix-text"><?php _e( 'Currently browsing', 'pinboard' ); ?> <?php echo $archive;<\/code><\/pre>\n
The text I wish to remove is on the last two lines; ‘Currently Browsing’<\/p>\n
How much\/little of the above code do I need to put into the child .php?<\/p>\n
Finally, on the Codex page it says I can declare conditionally, it gives this as an example. <\/p>\n
if ( ! function_exists( 'theme_special_nav' ) ) {\n    function theme_special_nav() {\n        \/\/  Do something.\n    }\n}<\/code><\/pre>\n
Is this relevant for the following addition I wish to make;<\/p>\n
function replace_howdy( $wp_admin_bar ) {\n $my_account=$wp_admin_bar->get_node('my-account');\n $newtitle = str_replace( 'Howdy,', 'Hello', $my_account->title );\n $wp_admin_bar->add_node( array(\n 'id' => 'my-account',\n 'title' => $newtitle,\n ) );\n }\n add_filter( 'admin_bar_menu', 'replace_howdy',25 );<\/code><\/pre>\n
[Please post code & markup between backticks or use the code button. Your posted code may now have been permanently damaged by the forum’s parser.]<\/em><\/p>\n
If so what would I replace the ‘theme_special_nav’ with, or have I got that totally wrong?<\/p>\n
Long query I know, sorry.  I am trying to find a local ‘buddy’ to mentor me on things WordPress!<\/p>\n
Cheers<\/p>\n
