Hello, I need a bit more help with the code from this thread:
https://toolset.com/forums/topic/limit-characters-display-in-view-for-custom-wysiwyg-field/

The code works if the characters in the wysiwyg field are not links... but mine are links. What shall I change in the code to make it work for links?

Thanks.

Hello. Thank you for contacting the Toolset support.

Well - what you mean when you say you have links with wyswyg?

Could you please share screenshot?

[PZ]

Sure.

Well - is it possible for you to send me access details and problem URL where you've added the limit character shortcode so I can check what's going wrong there.

*** 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 would like to know here:

Will your author field have only one author with one anchor tag respectively - as I understand you want to restrict the author name - correct?

What if you try to use following code in order to get anchor tag caption:

 preg_match_all('/<a .*?>(.*?)<\/a>/',$content,$matches);

Actually, sometimes I have more than one author in that field and what I want to limit is the overall number of characters. Like in the attached screenshot.

And I'm not sure where to put this code you gave me...

[Minesh]

Could you please check now. I've adjusted the shortcode as given under:

add_shortcode('limit_content', 'trim_shortcode');
 function trim_shortcode($atts, $content = '') {
    $content = wpv_do_shortcode($content);
    $length = (int)$atts['length'];
  
    preg_match_all('/<a .*?>(.*?)<\/a>/',$content,$matches);
  
   
   
    $content = join(" ",$matches[1]);
   
   
    if (strlen($content) > $length) {
        $content = substr($content, 0, $length) . '…';
    }
  
    // Strip HTML Tags
    $content = strip_tags($content);
  
    return $content;
}

Works!!! Thank you sooooo much 🙂 You're amazing.
