Hi,

I have just a question about weblink components. We would like to show a characters limit. It's possible ? if, what we can do to add the code and where.  ;D

Thank you very much for you help.

In PHP for UTF-8 encoded strings using Elxis eUTF class:

<?php
$word = 'This is a really looooooooooong string';
echo (eUTF::utf8_strlen($word) > 20) ? eUTF::utf8_substr($word, 0, 17).'...' : $word;
?>

For Latin encoded strings you can use the standard php functions (faster)

<?php
echo (strlen($word) > 20) ? substr($word, 0, 17).'...' : $word;
?>
