 truncating a dlookup into a label?

CCS2 + PHP Templates

I wish to limit the amount of characters returned into a label (ie:30) so
that I can produce "snippetts" of a news story....

In other words I need to take the output from a dlookup and then truncate
the output to about 30 chars in a label.

"The pony went past the gate and then..." - sort of thing, when the full
dump is about 1000 chars ( a full story)

Please help? or point me to somewhere with a soilution!

Owen

Hello Owen,

The important thing here is to ensure that you get a snippet not truncated
in the middle of a word. You could use function similar to this one (add it
to your Common.php or wherever you prefer):

// -------------------------------------------------
function smart_truncate($str2cut, $trig_val=30){
$newstr="";

if(strlen($str2cut) <= $trig_val)
return $str2cut;

$newlen=strrpos(substr($str2cut,0,$trig_val)," ");
if($newlen>0)
$newstr=substr($str2cut,0,$newlen);
else
$newstr=substr($str2cut,0,$trig_val);

return $newstr."...";
}

// -------------------------------------------------

Set the $str2cut parameter to the story you want to get a snip from, and
optionally set $trig_val to the maximum length of the resulting string
(defaults to 30 chars.)

To use:

$full_story=CCDLookUp("content_field", "news_table", "id_field=xxx", $db);
$snip_story=smart_truncate($full_story);


Regards,

Sixto

I think I must be thick!

I get errors...when I run the ccs project.

Is there a suitable reference aywhere to help me understand what parameters
to put where to make this work perhaps?
