Can I bring custom dynamic content from posts into a query loop?

I *could* create an ACF, add it into Elements, create a place with a Headline block where I could manually add the time in the post editor directly after publishing the post and seeing what the estimated reading time says on the single post page, but that seems like a "fix it with tape" kind of solution.

Hi Michelle,

Can you provide the link to your Blog page? I'll check how it's currently set up.

You may use the Private Information field for this: https://docs.generatepress.com/article/using-the-premium-support-forum/#private-information

Thanks. Yes, here is my Blog page. (It's under maintenance, so you'll have to log in.) My credentials are below.

That's odd. Your code should take into account the entire article.

Can you try this code instead to test?:

function tu_estimated_reading_time() {
    $post = get_post();
    $content = $post->post_content;
    $wpm = 300; // How many words per minute.

    $clean_content = strip_shortcodes( $content );
    $clean_content = strip_tags( $clean_content );
    $word_count = str_word_count( $clean_content );
	$m = floor($word_count / 200);
    $s = floor($word_count % $wpm / ($wpm / 60));
	if($m < 1) {
		$time = $s . ' second' . ($s <= 1 ? '' : 's');
	} else {
		$time = $m . ' minute' . ($m <= 1 ? '' : 's') . ', ' . $s . ' second' . ($s <= 1 ? '' : 's');
	}
	
    return $time;
}

add_filter( 'generate_post_author_output', function( $output ) {
    $output .= '<span class="read-time">Reading time: ' . tu_estimated_reading_time() . '</span>';

    return $output;
} );

Let us know how it goes.

I put the new code in and found that it doesn't pull up the time; It just leaves the shortcode [reading-time]...

Oh. I see what's the issue. Sorry, I didn't notice you're using a static page for your Blog Page.

You need to add the estimated time differently to make it work.

First, instead of a Shortcode Block, add a GB Headline Block instead.

Give it a text of Placeholder and a class cu-estimated-time.

Adding Custom Classes: https://wordpress.com/support/wordpress-editor/adding-additional-css-classes-to-blocks/

Then, add this Snippet:

function tu_estimated_reading_timeb() {
    $post = get_post();
    $content = $post->post_content;
    $wpm = 300; // How many words per minute.

    $clean_content = strip_shortcodes( $content );
    $clean_content = strip_tags( $clean_content );
    $word_count = str_word_count( $clean_content );
	$m = floor($word_count / 200);
    $s = floor($word_count % $wpm / ($wpm / 60));
	if($m < 1) {
		$time = $s . ' second' . ($s <= 1 ? '' : 's');
	} else {
		$time = $m . ' minute' . ($m <= 1 ? '' : 's') . ', ' . $s . ' second' . ($s <= 1 ? '' : 's');
	}
	
    return $time;
}

add_filter( 'render_block', function( $block_content, $block ) {
    if ( !is_admin() && ! empty( $block['attrs']['className'] ) && strpos( $block['attrs']['className'], 'cu-estimated-time' ) !== false ) {
		$myreplace1 = 'Placeholder';
		$myinsert1 = tu_estimated_reading_timeb();
        $block_content = str_replace( $myreplace1, $myinsert1 , $block_content );
    }

    return $block_content;
}, 10, 2 );

Adding PHP: https://docs.generatepress.com/article/adding-php/#code-snippets

Let us know how it goes.

Hello. I added the text and class, plus the code snippet and received this message:

Don't Panic
The code snippet you are trying to save produced a fatal error on line 73:

is_readable(): open_basedir restriction in effect. File(/dev/urandom) is not within the allowed path(s)

That's odd. Can I try to add the code myself to your site so I can see the error firsthand?

Yes, go ahead.

I was able to add it in Code Snippets.

Now, just add a GB Headline Block with text Placeholder and a class cu-estimated-time. Example: https://share.getcloudapp.com/WnuZJZkX

That worked! Now all that's left is making the single post page estimated times match the time stated on the blog page.

Which format do you prefer - the one currently on the Blog Page or the one on the Single Post Pages?

I like the format on the single post pages the best - "4 min read". Most important though is that the estimated times agree. My current post says 4 minutes and 52 seconds on the blog page, and 4 minutes on the single post page.

I see. Replace the code I added in Code Snippets with this:

function tu_estimated_reading_timeb() {
    $post = get_post();
    $content = $post->post_content;
    $wpm = 250; // How many words per minute.

    $clean_content = strip_shortcodes( $content );
    $clean_content = strip_tags( $clean_content );
    $word_count = str_word_count( $clean_content );
    $time = ceil( $word_count / $wpm );

    return $time . ' min read';
}

add_filter( 'render_block', function( $block_content, $block ) {
    if ( !is_admin() && ! empty( $block['attrs']['className'] ) && strpos( $block['attrs']['className'], 'cu-estimated-time' ) !== false ) {
		$myreplace1 = 'Placeholder';
		$myinsert1 = tu_estimated_reading_timeb();
        $block_content = str_replace( $myreplace1, $myinsert1 , $block_content );
    }

    return $block_content;
}, 10, 2 );

That should make them identical.
