Link ID in wordpress url - php

Question

Currently I am working on a wordpress website, but I stumbled upon a little problem.
I am using wp_page_menu to make a navbar to get to my other pages. Now it directs me to www.mysite.com/sport, but I need it to direct me to www.mysite.com/sport#header or www.mysite.com/sport/#header.
Does anyone know how I can do this?
I tried using different plugins, or changing the slug or permalink, but this didn't give me the result I wanted.
Thanks for helping guys!

Answer 1

Ok. Here is your code. I just override default walker of wordpress. Please focus on text #header in this code.
If you worry about this code. So you can go to file: ...wp-includes/post-template.php at line 1238. It same code but I have add #header after get_permalink().
Hope that help.
class WPSE_HasHeader_Custom_Walker extends Walker_Page {
function start_el( &$output, $page, $depth = 0, $args = array(), $current_page = 0 ) {
if ( $depth )
$indent = str_repeat("\t", $depth);
else
$indent = '';
extract($args, EXTR_SKIP);
$css_class = array('page_item', 'page-item-'.$page->ID);
if( isset( $args['pages_with_children'][ $page->ID ] ) )
$css_class[] = 'page_item_has_children';
if ( !empty($current_page) ) {
$_current_page = get_post( $current_page );
if ( in_array( $page->ID, $_current_page->ancestors ) )
$css_class[] = 'current_page_ancestor';
if ( $page->ID == $current_page )
$css_class[] = 'current_page_item';
elseif ( $_current_page && $page->ID == $_current_page->post_parent )
$css_class[] = 'current_page_parent';
} elseif ( $page->ID == get_option('page_for_posts') ) {
$css_class[] = 'current_page_parent';
}
$css_class = implode( ' ', apply_filters( 'page_css_class', $css_class, $page, $depth, $args, $current_page ) );
if ( '' === $page->post_title )
$page->post_title = sprintf( __( '#%d (no title)' ), $page->ID );
/** CHANGE LINK HERE **/
$output .= $indent . '<li class="' . $css_class . '">' . $link_before . apply_filters( 'the_title', $page->post_title, $page->ID ) . $link_after . '';
if ( !empty($show_date) ) {
if ( 'modified' == $show_date )
$time = $page->post_modified;
else
$time = $page->post_date;
$output .= " " . mysql2date($date_format, $time);
}
}
}
wp_list_pages(array(
'sort_column' => 'menu_order',
'title_li' => '',
'echo' => 1,
'walker' => new WPSE_HasHeader_Custom_Walker()
));

Thanks Mere Development. I thinks this is same idea with him but it much more simple in your case. Like this:
$link = wp_list_pages(array(
'sort_column' => 'menu_order',
'title_li' => '',
'echo' => 0,
));
echo preg_replace('/<a(.*)href="([^"]*)"(.*)>/', '<a$1href="$2#header"$3>', $link);

Christian's answer is great, and it got me thinking about alternative ways to do this, especially ones that allow you to use your wp_page_menu() function as originally requested. So here's another approach using a filter.
Add this function before your wp_page_menu() call, or in functions.php
function wp_list_pages_addhash($output) {
$dom = new DOMDocument;
$dom->loadHTML($output);
$links = $dom->getElementsByTagName('a');
foreach ($links as $link) {
$link->setAttribute('href', $link->getAttribute('href') . '#header');
}
$output = $dom->saveHTML();
return $output;
}
add_filter('wp_list_pages', 'wp_list_pages_addhash');
Then use your wp_page_menu call as you were originally in your theme:
wp_page_menu();
Explanation: It finds every href attribute of every link in the output of wp_list_pages and adds '#header' to the end. wp_page_menu in turn uses wp_list_pages to create output.
