Smarty

[gtgibson]

Is there a way using smarty to truncate at the first instance of a character or string? Obviously easy enough to do in PHP using a combiantion of substr() and strstr(), but would like to do this from a template.

specifically, I want to show an article and show it as a truncated version, cut off after the first paragraph. So i want to truncate at the first in stance of '\n'. Any ideas?

Obvioulsy in this instance, if '\n' is not found, it should display the whole string.

Cheers

{$text|regex_replace:"/(.*?)\n.*$/s":"\$1"}

but maybe it's worth to write a little modifier to encapsulate this:

[modfier.first_paragraph.php][php:1:c79588648c]<?php
function smarty_modifier_first_paragraph($str, $delim="\n") {
return preg_replace('/^(.*?)'.preg_quote($delim).'.*$/s', '$1', $str);

}

?>[/php:1:c79588648c]

or maybe with strpos and substr, YMMV.

OK, your first solution will be fine.

you don't need to register the modifier. put it in a file called "modifier.[modifier_name].php" in your plugins-directory and ensure the function in it is named "smarty_modifier_[modifier_name]". smarty will autoload and register it for you as soon as a template uses it.
