hey,
i used this great advice here for creating excerpts from a custom field:

https://toolset.com/forums/topic/i-would-like-to-show-a-excerpt-of-a-custom-user-field-that-i-have-created/

point is, my custom field is not WYSIWYG, but multiline textarea.

when i present it in the content template, without the excerpt shortcode, the breaks are there, e.g:

line one
line two
etc...

but when i use the excerpt shortcode, the breaks are gone, e.g:

line one line two etc...

this is the snippet:

function custom_trim_field( $atts, $content = null ) {
    // Extract any arguments passed
    extract( shortcode_atts( array(
        'length'    => 40, // Number of words to show
        'more'      => 'קראו עוד...',  // Text to show at the end of the filtered text
        'field'     => '',
        'postid'    => '0'
    ), $atts ) );
    global $post;
    if ( empty($field) ){
        return;
    }
    if ( !isset($post) ){
        return;
    }
    $field = types_render_field($field, array("raw"=>"true"));
 
    $excerpt_more_link = '&nbsp;<a href="' . get_the_permalink($postid) . '">' . $more . '</a>';
    $output = wp_trim_words( $field, $length, $excerpt_more_link );  // create the filter text
    return $output;  // return filter text
 
    //example: [trimfield length="100" more="Read more..." field="wysiwyg" postid="[wpv-post-id]"][/trimfield]
}
add_shortcode( 'trimfield', 'custom_trim_field' );

any ideas?

thx!

Hello. Thank you for contacting the Toolset support.

Well - can you please share problem URL where you want to display excerpt and what is your excerpt field with which you have issues that it does not render line breaks.

*** Please make a FULL BACKUP of your database and website.***
I would also eventually need to request temporary access (WP-Admin and FTP) to your site. Preferably to a test site where the problem has been replicated if possible in order to be of better help and check if some configurations might need to be changed.

I would additionally need your permission to de- and re-activate Plugins and the Theme, and to change configurations on the site. This is also a reason the backup is really important. If you agree to this, please use the form fields I have enabled below to provide temporary access details (wp-admin and FTP).

I have set the next reply to private which means only you and I have access to it.

Well - I've to change the code you added a bit.

I've moved the code you added to your theme's functions.php file to Toolset's custom code section

Here is the modified code:

// Put the code of your snippet below this comment.
function custom_trim_field( $atts, $content = null ) {
    // Extract any arguments passed
    extract( shortcode_atts( array(
        'length'    => 40, // Number of words to show
        'more'      => 'קראו עוד...',  // Text to show at the end of the filtered text
        'field'     => '',
        'postid'    => '0'
    ), $atts ) );
    global $post;
    if ( empty($field) ){
        return;
    }
    if ( !isset($post) ){
        return;
    }
    
	//$field = types_render_field($field, array("raw"=>"true"));
	$field = nl2br(get_post_meta($atts['postid'],'wpcf-'.$field,true));
	
 
    $excerpt_more_link = '&nbsp;<a href="' . get_the_permalink($postid) . '">' . $more . '</a>';
//    $output = wp_trim_words( $field, $length, $excerpt_more_link );  // create the filter text
	
 $words = preg_split("/[\n\r\t ]+/", $field, $length + 1, PREG_SPLIT_NO_EMPTY);
    if ( count($words) > $length ) {
      
        
        array_pop($words);
        $text = implode(' ', $words);
        $field = $field . $excerpt_more_link;
    } else {
        $field = implode(' ', $words);
    }
	
	 return $field;  // return filter text
 
    //return $output;  // return filter text
 
    //example: [trimfield length="100" more="Read more..." field="wysiwyg" postid="[wpv-post-id]"][/trimfield]
}
add_shortcode( 'trimfield', 'custom_trim_field' );

I can see that it works as expected now. Can you please confirm.
