Question

How can I limit the text to say 100 characters from the get_post_meta tag?

I need to grab the text in this style:

<?php echo get_post_meta($relationship->ID, 'company_description', true ); ?> 

This is how I would normally limit the text but I don’t know how to combine it with the syntax above:

<?php echo substr($fields->company_description,0,100) . "..."; ?>

The most readable way:

$text = get_post_meta($relationship->ID, 'company_description', true);
echo substr($text, 0, 100) . "...";

Then of course, you could also nest the function calls, which probably sucks in terms of readability:

echo substr(get_post_meta($relationship->ID, 'company_description', true), 0, 100) . "...";

By the way: If company_description might contain raw HTML, you’ll probably want to run strip_tags() over it before getting a substring – not stripping HTML would get you in trouble in the long run otherwise.

$text = strip_tags(get_post_meta($relationship->ID, 'company_description', true));
echo substr($text, 0, 100) . "...";
