Trying to modify "Read more" link in parent theme - php

Question

My parent them has a custom "Read more" function. I want to change the text and add to my child theme function.php.
Here is parent them function
add_filter( 'excerpt_length', 'newslite_excerpt_length', 999 );
if ( ! function_exists( 'newslite_implement_read_more' ) ) :
function newslite_implement_read_more( $more ) {
$flag_apply_excerpt_read_more = apply_filters( 'newslite_filter_excerpt_read_more', true );
if ( true !== $flag_apply_excerpt_read_more ) {
return $more;
}
$output = $more;
$read_more_text = __('continue reading','newslite');
if ( ! empty( $read_more_text ) ) {
$output = ' <div class="read-more-text">' . esc_html( $read_more_text ) . '</div>';
$output = apply_filters( 'newslite_filter_read_more_link' , $output );
}
return $output;
}
endif;
add_action( 'excerpt_more', 'newslite_implement_read_more' );

Answer 1

I would just remove their function, and create your own custom one.
add_action( 'excerpt_more', 'custom_newslite_implement_read_more', 9999 );
function custom_newslite_implement_read_more( $more ) {
remove_filter( 'excerpt_length', 'newslite_excerpt_length', 999 );
$flag_apply_excerpt_read_more = apply_filters( 'custom_newslite_filter_excerpt_read_more', true );
if ( true !== $flag_apply_excerpt_read_more ) {
return $more;
}
$output = $more;
$read_more_text = __('read more','newslite'); // change read more to whatever you want
if ( ! empty( $read_more_text ) ) {
$output = ' <div class="read-more-text">' . esc_html( $read_more_text ) . '</div>';
$output = apply_filters( 'custom_newslite_filter_read_more_link' , $output );
}
return $output;
}

Answer 2

Try code:
function new_excerpt_more($more) {
global $post;
return '… ' . 'Read More »' . '';
}
add_filter('excerpt_more', 'new_excerpt_more');

Answer 3

I copied the parent function (everything inside the if statement) to my child functions.php file. then simply changed the text string. This worked.
function newslite_implement_read_more( $more ) {
$flag_apply_excerpt_read_more = apply_filters( 'newslite_filter_excerpt_read_more', true );
if ( true !== $flag_apply_excerpt_read_more ) {
return $more;
}
$output = $more;
$read_more_text = __('More','newslite');
if ( ! empty( $read_more_text ) ) {
$output = ' <div class="read-more-text">' . esc_html( $read_more_text ) . '</div>';
$output = apply_filters( 'newslite_filter_read_more_link' , $output );
}
return $output;
}
