Tell us what you are trying to do?

I'm developing a directory site that will take input from user forms on the front-end. One of the custom fields in this form is for a bio (or introduction) section. I used a custom field for this rather than the standard WordPress content field because I don't want the user to have access to the wysiwyg editor; I want to keep content uniform...

The challenge I have is, when I go to create my front-end grid for displaying directory results, I'm unable to limit the number of words/characters that are output from the (bio/intro) custom field. I'd like these blocks to only show ~20 words, just to keep the grid clean. Basically, I'd like to control this custom field's output similar to the way we can configure the standard WordPress excerpt. Is there a way to do that? If not, is there a way for me to use the standard WordPress content field without the user seeing/accessing all the styling options?

Thank you for contacting us and I'd be happy to assist.

To limit the output from any field to a certain number of words, you can register a custom shortcode:

function word_trim_custom_func( $atts, $content = null ) {
	$a = shortcode_atts( array(
		'words' => '20',
		'more' => '...',
	), $atts );

	return wp_trim_words( apply_filters('the_content', $content), $a['words'], $a['more'] );
add_shortcode( 'word_trim_custom', 'word_trim_custom_func' );

The above code snippet can be included through either Toolset's custom code feature ( ref: ) or through the active theme's "functions.php" file.

After that, you can use this new shortcode in your template through a "Fields and Text" block, like this:

[word_trim_custom words="40" more="...."][types field='post-text-area'][/types][/word_trim_custom]

Please note, how I've used the Toolset Type fields shortcode to show the content from a "post-text-area" field, inside the new custom shortcode ( [types field='post-text-area'][/types] ) and set the limit of words to 40 and the more text that is appended at the end to '....'.
