Custom "continue reading" in Twentyten

Yes to all three.

I tried searching for the content in the SQL database – and searching for the field name – I can’t find either, but they MUST be there somewhere.

Could there be a problem with the way the loop calls the function?:

<div class="entry-content">
				<?php the_excerpt( __( 'Continue reading <span class="meta-nav">&rarr;</span>', 'twentyten' ) ); ?>
				<?php wp_link_pages( array( 'before' => '<div class="page-link">' . __( 'Pages:', 'twentyten' ), 'after' => '</div>' ) ); ?>
			</div><!-- .entry-content -->

the_excerpt() has no parameter – the above code is and was always unexplained to me.

the ‘read-more’ text for the excerpt comes from a function in functions.php of the twenty ten theme:

/**
 * Adds a pretty "Continue Reading" link to custom post excerpts.
 *
 * To override this link in a child theme, remove the filter and add your own
 * function tied to the get_the_excerpt filter hook.
 *
 * @since Twenty Ten 1.0
 * @return string Excerpt with a pretty "Continue Reading" link
 */
function twentyten_custom_excerpt_more( $output ) {
	if ( has_excerpt() && ! is_attachment() ) {
		$output .= twentyten_continue_reading_link();
	}
	return $output;
}
add_filter( 'get_the_excerpt', 'twentyten_custom_excerpt_more' );

and this:

/**
 * Returns a "Continue Reading" link for excerpts
 *
 * @since Twenty Ten 1.0
 * @return string "Continue Reading" link
 */
function twentyten_continue_reading_link() {
	return ' <a href="'. get_permalink() . '">' . __( 'Continue reading <span class="meta-nav">&rarr;</span>', 'twentyten' ) . '</a>';
}

if you haven’t changed anything there, my suggested code should work (i would hope – tested in a child theme)

you could paste the code of your functions.php into a https://wordpress.pastebin.com/ and post the link here for someone to check.

Thanks

I appreciate this, I also hope it will help others.

Functions.php is saved at: https://wordpress.pastebin.com/wPVm5Q9M

this is the full functions.php of your child theme?

have you changed anything in the functions.php of your parent theme, the Twenty Ten?

you can also try:

-change to the Twenty Ten theme and add the code directly into the functions.php of that theme;

-deactivate all plugins, and when that solves the problem, re-activate one plugin after the other to see which triggers the problem.

a link to your site might help to investigate this problem.

Yes, that’s it for functions.php – I had others previously, but have since stripped it back to nothing.

I’m sure nothing is changed in the parent Twenty Ten functions, but to make certain, I’ll reload a fresh file.

I’ll try making the change to the parent function.php file later – maybe later today.

First I’m going to deactivate plug-ins and investigate this as a potential problem.

My site is https://billbennett.co.nz

Definitely not a plug in problem…just deactivated and nothing changed

Moving the code to the parent functions.php didn’t seem to make any difference.

i am at my limits, to what to suggest.
i tried my suggested code locally in the twenty ten theme, and in a child theme; as well online in my twenty ten child theme based blog.
no problems.
however, each installation is unique, and the non-working might be caused by something that seems totally unrelated.

an alternative way is to edit all occurrances of
<?php the_content( __( 'Continue reading <span class="meta-nav">&rarr;</span>', 'twentyten' ) ); ?>
in loop.php (copied into the child theme; occurs twice – lines 110 and 138) to include the custom field text; for instance so:

<?php $read_more = get_post_meta($post->ID, 'cont_read', true);
$read_more = $read_more ? $read_more : 'Continue reading';
the_content( __( $read_more . ' <span class="meta-nav">&rarr;</span>', 'twentyten' ) ); ?>

and add a section in functions.php of the child theme:
for instance: https://wordpress.pastebin.com/8EuqBfbH

Thanks Alchymyth. I think you’ve already gone well beyond the call of duty.

I’ll give this other suggestion a try later.

This is now working, along the way I had to swap out the references to

<?php the_content

to

<?php the-excerpt

but that fixed it. Maybe this was the problem in the first place?
