Display full post if only one post in category

Open your category template file and replace

<?php the_excerpt(); ?>

with

<?php
if ($wp_query->found_posts == 1)
	the_content();
else
	the_excerpt();
?>

I don’t have a category template… the closest I have is in custom_functions

/*this function allows for the auto-creation of post excerpts*/
function truncate_post($amount,$echo=true) {
	global $post, $shortname;

	$postExcerpt = '';
	$postExcerpt = $post->post_excerpt;

	if (get_option($shortname.'_use_excerpt') == 'on' && $postExcerpt <> '') {
		if ($echo) echo do_shortcode($postExcerpt);
		else return do_shortcode($postExcerpt);
	} else {
		$truncate = $post->post_content;

		$truncate = preg_replace('@\[caption[^\]]*?\].*?\[\/caption]@si', '', $truncate);

		if ( strlen($truncate) <= $amount ) $echo_out = ''; else $echo_out = '...';
		$truncate = apply_filters('the_content', $truncate);
		$truncate = preg_replace('@<script[^>]*?>.*?</script>@si', '', $truncate);
		$truncate = preg_replace('@<style[^>]*?>.*?</style>@si', '', $truncate);

		$truncate = strip_tags($truncate);

		if ($echo_out == '...') $truncate = substr($truncate, 0, strrpos(substr($truncate, 0, $amount), ' '));
		else $truncate = substr($truncate, 0, $amount);

		if ($echo) echo $truncate,$echo_out;
		else return ($truncate . $echo_out);
	};

/*this function allows for the auto-creation of post excerpts*/
function truncate_post($amount,$echo=true) {
	global $post, $shortname;

	$postExcerpt = '';
	$postExcerpt = $post->post_excerpt;

	if (get_option($shortname.'_use_excerpt') == 'on' && $postExcerpt <> '') {
		if ($echo) echo do_shortcode($postExcerpt);
		else return do_shortcode($postExcerpt);
	} else {
		$truncate = $post->post_content;

		$truncate = preg_replace('@\[caption[^\]]*?\].*?\[\/caption]@si', '', $truncate);

		if ( strlen($truncate) <= $amount ) $echo_out = ''; else $echo_out = '...';
		$truncate = apply_filters('the_content', $truncate);
		$truncate = preg_replace('@<script[^>]*?>.*?</script>@si', '', $truncate);
		$truncate = preg_replace('@<style[^>]*?>.*?</style>@si', '', $truncate);

		$truncate = strip_tags($truncate);

		if ($echo_out == '...') $truncate = substr($truncate, 0, strrpos(substr($truncate, 0, $amount), ' '));
		else $truncate = substr($truncate, 0, $amount);

		if ($echo) echo $truncate,$echo_out;
		else return ($truncate . $echo_out);
	};

Then place the condition around the function call inside whichever template used to display category pages. Like this:

<?php
if ( is_category() && $wp_query->found_posts == 1 )
	the_content();
else
	truncate_post();
?>

Ok, I just am not sure where to put it in that code specifically….

Can you paste your template file in https://wordpress.pastebin.com/ so I see where to put it?

/*this function allows for the auto-creation of post excerpts*/
function truncate_post($amount,$echo=true) {
	global $post, $shortname;

	$postExcerpt = '';
	$postExcerpt = $post->post_excerpt;

	if (get_option($shortname.'_use_excerpt') == 'on' && $postExcerpt <> '') {
		if ($echo) echo do_shortcode($postExcerpt);
		else return do_shortcode($postExcerpt);
	} else {
		$truncate = $post->post_content;

		$truncate = preg_replace('@\[caption[^\]]*?\].*?\[\/caption]@si', '', $truncate);

		if ( strlen($truncate) <= $amount ) $echo_out = ''; else $echo_out = '...';
		$truncate = apply_filters('the_content', $truncate);
		$truncate = preg_replace('@<script[^>]*?>.*?</script>@si', '', $truncate);
		$truncate = preg_replace('@<style[^>]*?>.*?</style>@si', '', $truncate);

		$truncate = strip_tags($truncate);

		if ($echo_out == '...') $truncate = substr($truncate, 0, strrpos(substr($truncate, 0, $amount), ' '));
		else $truncate = substr($truncate, 0, $amount);

		if ($echo) echo $truncate,$echo_out;
		else return ($truncate . $echo_out);
	};
}

You need to show me the template that’s using the function to display category posts (maybe archive.php), not the function itself.

Edit: Which theme are you using?

It is there.. thanks for all your help!!

No luck, huh?

Try this:

function truncate_post($amount,$echo=true) {
	global $post, $shortname, $wp_query;

	if ( is_category() && $wp_query->found_posts == 1 ) {
		if ($echo)
			echo get_the_content();
		else
			return get_the_content();
	} else {
		$postExcerpt = '';
		$postExcerpt = $post->post_excerpt;

		if (get_option($shortname.'_use_excerpt') == 'on' && $postExcerpt <> '') {
			if ($echo) echo do_shortcode($postExcerpt);
			else return do_shortcode($postExcerpt);
		} else {
			$truncate = $post->post_content;

			$truncate = preg_replace('@\[caption[^\]]*?\].*?\[\/caption]@si', '', $truncate);

			if ( strlen($truncate) <= $amount ) $echo_out = ''; else $echo_out = '...';
			$truncate = apply_filters('the_content', $truncate);
			$truncate = preg_replace('@<script[^>]*?>.*?</script>@si', '', $truncate);
			$truncate = preg_replace('@<style[^>]*?>.*?</style>@si', '', $truncate);

			$truncate = strip_tags($truncate);

			if ($echo_out == '...') $truncate = substr($truncate, 0, strrpos(substr($truncate, 0, $amount), ' '));
			else $truncate = substr($truncate, 0, $amount);

			if ($echo) echo $truncate,$echo_out;
			else return ($truncate . $echo_out);
		};
	}
}

I am sorry you are getting frustrated… I don’t know what file you are talking about – I am not a php expert. I am using Elegant Themes – Interphase, but I don’t know what file you would like…. sorry! ?? This may not be possible… ??

You’re using a premium theme so I can’t get it but you could try the modification I’ve just posted. Can’t guarentee it’ll work as I don’t know how the function is been used.
