combining truncate and replace

I am trying to remove the commas from my meta_keywords variable and replace them with nothing "" in this line

Code:

{$_meta_keywords|truncate:"130":"":false|escape}

and truncate it to the 5th word. (I haven't started on the "5th word" part) This is what I was trying without much success along with a couple of other variations.

Code:

{$_meta_keywords|replace:",":""|truncate:"130":"":false|escape}

Anyone know how to do that?

Re: combining truncate and replace

I got replacing the commas worked out and truncating to the 100th character while keeping the last full word intact. Looks like this now.

Code:

{$_meta_keywords|truncate:"100":"":false|replace:',':''|escape}

using this to create unique alt tags for my logo image on each page. The alt tag will match with the first few words of my meta_keywords on each page.

Re: combining truncate and replace

I was wondering if anyone knows if it is possible to truncate a string but to do it at the first "," instead of at a certain number of characters? For example

scented candles, votives, candle holders

would be shown only as

scented candles

thanks

Re: combining truncate and replace

You can create a custom Smarty modifier, e.g. like this:

1. create a new Smarty modifier plugin -> "include/templater/plugins/modifier.mymodifier.php" with the following content:

PHP Code:


		
			
<?php 

if (!defined('XCART_START')) { header("Location: ../../../"); die("Access denied"); } 

function smarty_modifier_mymodifier($param) {
   $param = explode(',', $param);
   $param = isset($param[0]) ? $param[0] : $param;
   return $param;
} 

?>

2. add further use something like:

{$_meta_keywords|mymodifier}
