I’ve been browsing the phx modifiers at http://wiki.modxcms.com/index.php/PHx/CustomModifiers and I was wondering if there was a way to show just the first paragraph? like phx:word_limit and phx:character_limit but something like phx:paragraph_limit?

Thanks!

Hi Hat-rack,

not sure if it’s 100% the right way to do it, but i just tested it, and it seems to work

create a new snippet and call it "phx:firstp" with the content of:

<?php
$firs_par = explode( '</p>', $output );
$firs_par_output = strip_tags( $firs_par[0] );
return '<p>'.( $firs_par_output ).'</p>';
?>

then in your Ditto Template-Chunk use it like this: [+content:firstp+]

going to test it further

Maybe

<?php
return strstr($output,'</p>',TRUE).'</p>';
?>

is faster. but im not sure. and its not tested. if you have content before the first "<p>" you can do something like that:

<?php
return strstr(strstr($output,'<p>'),'</p>',TRUE).'</p>';
?>

ah, thanks...i think strstr before_needle is only available from PHP 5.3 on (nicer solution though)
