How to add Excerpt or truncate a textarea in search page result

[Edward Ver]

Hello everyone,

I made a search page and it's working fine. But, I want to truncate the output the textarea of the search result text. 

I want to limit the output of the "maintext" in the result page. Thanks in advance.

 echo "<div class='summary'>$match->maintext</div></li>";

There are several ways to truncate text.

1. In CSS, see https://developer.mozilla.org/en-US/docs/Web/CSS/text-overflow
2.  In PHP, https://www.php.net/manual/en/function.substr.php
3.  In ProcessWire, https://processwire.com/api/ref/sanitizer/truncate/

Number 3 is my choice
