How to convert page slug string into Title string for breadcrumbs?

There are some simple php functions to do this.

// Change hypens to whitespace
$title = str_replace( '-', ' ', $title );
// Capitalise every word in your title
$title = ucwords( $title );

You can find documentation for these functions on php.net
https://php.net/manual/en/function.ucwords.php
https://php.net/manual/en/function.str-replace.php

Good luck!

THANK YOU FOR YOUR QUICK REPLY, BUT PHP IS NOT MY STRENGHT AND I HAVE NO IDEA HOW TO DO IT.
THAT LINE THAT I ADDED
” $link[‘slug’] = get_post_field( ‘post_name’, get_post() ); ”
WAS A PURE MIRACLE THAT I FOUND IT AND IT WORKED.
I HAVE INCLUDED THE SNIPPET WHERE THE MAGIC HAPPENS. IF YOU CAN PLEASE TELL ME WHERE AND WHAT TO INCLUDE, I WOULD BE VERY GREATFUL. THANK YOU

Hey toddius,

You should never alter a plugin file itself. If you’ll update the plugin you’ll lose your modifications.

You can modifie the plugin with hooks or filters.

This code should do your trick;

function my_breadcrumb_filter() {
	$link['slug'] = get_post_field( 'post_name', get_post() );

	// Change hypens to whitespace
	$breadcrumb = str_replace( '-', ' ', $link['slug'] );
	// Capitalise every word in your title
	$breadcrumb = ucwords( $breadcrumb );

	return $breadcrumb;
}

add_filter('wp_seo_get_bc_title', 'my_breadcrumb_filter' );

You can put this snippet in your functions.php or in a custom plugin.
