Hello, I need a bit more help with the code from this thread:

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?

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?

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...

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.
