Is there a way to call the character count of a placeholder and use that in a conditional output modifier?

As an example: If the content of an article/resource is greater than a certain number of characters, it won't just add ellipses, but also show a link to the full article? This is what I have now, but I can't figure out how to use character count for conditional statements.

[[+content:ellipsis=`300`]]

Is this possible?

Thanks guys!

Hi maroonlover,
you could write a snippet that does this stuff for you.
Simple Example:

<?php
$output = $input;
$nChars = 200;
if(strlen($input) > $nChars){
 $output = substr($input,0,$nChars);
 $output .= '... <a href="'.$modx->makeUrl($articleId).'">read</a>';
}
return $output;

Then call your snippet like this:

[[snippet? &input=`[[+content]]` &articleId=`[[+id]]`]]

Could do that with output modifiers if you want to, tho a snippet would probably be more flexible:

[[+content:len:gt=`200`:then=`<a href="[[~[[+id]]]]">Read more</a>`:else=`That's all folks!`]]
