Franky57 on "How to override wp_list_pages and wp_list_bookmarks without modify core code ?"

Hi all !

I am finding a way to override some core functions of WordPress (wp_list_pages and wp_list_bookmarks) within my function.php theme file because I am so tired to always modify core code when I update WordPress.

In the way to make easier my css styling, I proceed of this changes in post-template.php and bookmark-template.php core file.

In one hand, I added in the $default array of the post-template.php wp_list_pages function the following parameters:

'before' => '', 'after' => ''

in the way to modify the Walker_Page start_el method at line 1062 from:

$output .= $indent . '<li class="' . $css_class . '"><a href="' . get_permalink($page->ID) . '">' . $link_before . apply_filters( 'the_title', $page->post_title, $page->ID ) . $link_after . '</a>';

to:

$output .= $indent . '<li class="' . $css_class . '">' . $before . '<a href="' . get_permalink($page->ID) . '">' . $link_before . apply_filters( 'the_title', $page->post_title, $page->ID ) . $link_after . '</a>' . $after;

(as we can see these parameters in the wp_list_bookmarks function)

In the other hand, I added in the $default array of the bookmark-template.php _walk_bookmarks and wp_list_bookmarks functions the following parameter:

'relativepath' => 0

in the way to modify the part of code at line 102 in _walk_bookmarks function from:

if ( $bookmark->link_image != null && $show_images ) {
	if ( strpos($bookmark->link_image, 'http') === 0 )
		$output .= "<img src=\"$bookmark->link_image\" $alt $title />";
	else // If it's a relative path
		$output .= "<img src=\"" . get_option('siteurl') . "$bookmark->link_image\" $alt $title />";

	if ( $show_name )
		$output .= " $name";
	} else {
		$output .= $name;
}

to:

if ( $bookmark->link_image != null && $show_images ) {
	if ( $relativepath == 0 ) {
		if ( strpos($bookmark->link_image, 'http') === 0 )
			$output .= "<img src=\"$bookmark->link_image\" $alt $title />";
		else // If it's a relative path
			$output .= "<img src=\"" . get_option('siteurl') . "$bookmark->link_image\" $alt $title />";
	} else {
		$output .= "<img src=\"" . wp_make_link_relative($bookmark->link_image) . "\" $alt $title />";
	}

	if ( $show_name )
		$output .= " $name";
} else {
	$output .= $name;
}

(I need to have relative path for the src attribute of my img tag and I don't find on other way even with hooks and filters)

I know it's dangerous to modify core code but I don't find on internet the way to obtain what I needed without hacking WordPress core files.

Is anybody have an idea to get around my hacking code ?

Thanks
