This isn’t exactly how the plugin’s designed to be used. There’s no functionality to limit the biography text to a set number of characters but I think there’s 2 ways you might be able to achieve this …
Both of these use the plugin’s shortcode, either in wildcard mode if you want the Biography Box for all your users displayed, or repeat the shortcode, once per required user.
1. If your user’s don’t have the Biographical Excerpt filled out in their profiles, configure the shortcode to use this via the type=excerpt
shortcode attribute. This will effectively emit empty biography text. Something along the lines of …
[wp-biographia user="*" type="excerpt"]
… assuming wildcard mode in this example.
Or …
2. Wrap the HTML emitted by the shortcode in a specially identified <div>
and then load some custom CSS to set wp-biographia-text
within that <div>
to have display: none
set. Something along the lines of …
<div class="restricted-bio">
<?php do_shortcode('[wp-biographia user="*"]'); ?>
</div>
… with CSS along the lines of …
.restricted-bio wp-biographia-text {
display: none;
}
I haven’t actually tried this, but in principle it should work though both work-arounds may need some tweaking. Hope this helps and makes sense
