Limit characters in description and show a link to read more

shimazakinori · August 23, 2023, 6:56pm

Hi! I would like to write a hook in function.php which allows me to display up to a limit of characters in the listing page. And if it’s longer than threshhold, I would like to redirect to a URL.

I am testing with this code below but it’s not working. Am I doing something wrong?

My guess is in the ‘hivepress/v1/forms/…’ part.

Thank you for your attention.

//Limit Characters

add _filter (
'hivepress/v1/forms/listing_description',
'hivepress/v1/forms/listing_CustomURL',  //This is a custom attribute
function ($description, $CustomURL) {
    // Check if the description has more than 250 characters
    if (strlen($description) > 250) {
        // Trim the description to 250 characters
        $trimmed_description = substr($description, 0, 250);
        
        // Append ellipsis (...) to indicate that the description was truncated
        $trimmed_description .= '...';
        $trimmed_description .= ' <a href="' . esc_url($CustomURL) . '">Read more</a>';

        
        return $trimmed_description;
    } else {
        // Return the original description if it's 250 characters or less
        return $description;
    },
1000
}

Unfortunately it will not work this way, there’s no such hook. The best way is overriding the listing/view/page/listing-description.php template part via a child theme, then you can customize it’s HTML accordingly (this template part shows the description on the listing page).
