How To Select Text From Content

I have tried searching for this, but I'm really unsure what I would use as a query to find the answer on these forums, so please forgive me if I've missed something. My question is as follows.

I am including the introtext from content in my template. I want to format this text, specifically I want to apply a span tag to the first letter. This styling gives me a really large first letter, and the rest of the font regular text. So far I have this.

[[*introtext:limit=`1`]]

In between the span tags on my template. The rest of this is where I'm getting hung up. I want to have the rest of the introtext follow that immediately, HOWEVER, I want it to be introtext minus the first letter (since I've already inserted/made it huge). Basically

 [[introtext:-firstletter]]

If I could code colloquially

Is there any way to do this??? I'm fairly new so if you can be specific with what I should look at, it would be appreciated.

create a new snippet (substring):

$options=explode(',',$options);
return count($options)>1 ? substr($input,$options[0],$options[1]) : substr($input,$options[0]);

and use it this way:

<span>[[*introtext:substring=`0,1`]]</span>[[*introtext:substring=`1`]]

just added this here:

Very nice.

Being a speed freak, I would be inclined to do it with a single snippet call and no output modifiers:

[[!MyIntroText]]

<?php
/* MyIntroText snippet */

$txt = $modx->resource->get('introtext');

return '<span class="FirstLetter">' . substr($txt, 0, 1) . '</span>' . substr($txt, 1);

You could also make it more generic (so it could be used with other fields, (e.g., description or content):

[[!FirstLetter? &field=`introtext`]]

<?php
/* FirstLetter snippet */

$txt = $modx->resource->get($scriptProperties['field']);

return '<span class="FirstLetter">' . substr($txt, 0, 1) . '</span>' . substr($txt, 1);

Hey guys,

Thanks for helping out a noob here. I'm really surprised how supportive the forums are here... was on a drupal forum (when I still used that clunker) asking for something similar and I got nothing as quick or too the point. You guys definitely solved my problem that my 2 hours of research sure couldn't ;-)

Muchly appreciated

Greg
