Why can't I override WP filter 'excerpt_more' through my theme child functions?
I can't seem to get my functions to work for changing the excerpt_more
Twenty Eleven parent theme filter .
I suspect it might actually be add_action( 'after_setup_theme', 'twentyeleven_setup' );
, but I even tried to remove_filter( 'excerpt_more', 'twentyeleven_auto_excerpt_more' )
get rid of the Twenty Eleven feature and yet my features don't change anything ...
You can help?
Here's the complete code for functions.php:
Here's the functions I added to /mychildtheme/functions.php
function clientname_continue_reading_link() {
return ' <a href="'. esc_url( get_permalink() ) . '">' . __( 'Read more... <span class="meta-nav">→</span>', 'clientname' ) . '</a>';
}
function clientname_auto_excerpt_more( $more ) {
return ' …' . clientname_continue_reading_link();
}
add_filter( 'excerpt_more', 'clientname_auto_excerpt_more' );
Thank,
Wasps

Ok, so after a lot of frustrations, I found a solution to this (I thought "Kids Themes" was meant to speed things up !?). I believe this works because "after_theme_setup" is triggered after the parent theme has been installed, which means you can remove / override Twenty Eleven features at this point.
If I understood correctly, according to this documentation, the Child Theme is fired first, then the parent, and then the after_theme_setup bit of code in the child.php Child Theme file:
http://codex.wordpress.org/Child_Themes#Using_functions.php
and
http://codex.wordpress.org/Plugin_API/Action_Reference/after_setup_theme
This is what's in my functions.php Child Theme file, hope this helps someone:
// ------------------------------------------------------------------
// // !AFTER_SETUP_THEME
// ------------------------------------------------------------------
/* Set up actions */
add_action( 'after_setup_theme', 'osu_setup' );
if ( ! function_exists( 'osu_setup' ) ):
function osu_setup() {
// OVERRIDE : SIDEBAR GENERATION FUNCTION - NO WIDGETS FOR THIS SITE
remove_action( 'widgets_init', 'twentyeleven_widgets_init' ); /* Deregister sidebar in parent */
// OVERRIDE : EXCERPT READ MORE LINK FUNCTION
function osu_readon_link() {
return '...<a href="'. get_permalink() . '" class="readmore">' . __( 'Read More...', 'clientname' ) . '</a>';
}
// Function to override
function osu_clientname_custom_excerpt_more( $output ) {
if ( has_excerpt() && ! is_attachment() ) {
// $output = trim($output);
$output .= osu_readon_link();
}
return $output;
}
remove_filter( 'get_the_excerpt', 'twentyeleven_custom_excerpt_more' );
add_filter( 'get_the_excerpt', 'osu_clientname_custom_excerpt_more' );
remove_filter( 'excerpt_more', 'twentyeleven_auto_excerpt_more' );
add_filter( 'excerpt_more', 'osu_readon_link' );
// OVERRIDE : EXCERPT LENGTH FUNCTION
function osu_clientname_excerpt_length( $length ) {
return 30;
}
remove_filter( 'excerpt_length', 'twentyeleven_excerpt_length' );
add_filter( 'excerpt_length', 'osu_clientname_excerpt_length' );
}
endif; // osu_setup

Your own answer complicates things and really shouldn't be necessary. I couldn't explain why my answers are because I found this in another answer. But in any case, you can ALWAYS override functions from the parent theme in the child theme, although sometimes you do need to use remove_filter()
OR in advance, as in this case, all you have to do is increase the priority of your added filter, in your case:
add_filter( 'excerpt_more', 'clientname_auto_excerpt_more', 11 );
This should do the trick. If not, increase the number. Thanks to this answer :
