[SOLVED] Smarty Truncate Problem

So this is a strange one...

I have a news summary that looks like this:

Code:

{if $entry->content}
<div class="newstext">
{eval var=$entry->content|truncate:100}
<p><a class="readmore" href="{$entry->moreurl}">read more &rarr;</a></p>
</div>
{/if}

My tags are inside the article, which outputs:

Code:

<div class="newstext">
<p>As part of our commitment to ensure you reach your personal Health Goals, (company name) have...
<p><a class="readmore" href="#thelink">read more &rarr;</a></p>
</div>

Problem is, as you can see the trailing is truncated too, meaning that the page doesn't validate! And I potentially will have display issues too.

Anybody have an idea how to make it NOT truncate the trailing tag? I've looked everywhere!

Thanks in advance.

The problem is not knowing where the is going to end, if it has 2 paragraphs or ? but you could add after the summary truncate call in the summary template...

The summarize, and truncate modifiers are designed to work with text, not html. They count characters, or words... they don't care about what markup is there.

If you want to display the first N characters of 'text' you have to convert the html to text first.

|strip_tags|truncate

should do the trick.

Perfect...

Code:

|strip_tags|truncate

Worked a treat! Thank you.

If you want to truncate just the first sentence you can use the modifier below which I recently came across. Just copy the code and upload to /lib/smarty/plugins name it modifier.first_sentence.php

In you smarty tag just use |first_sentence

Calguy how about adding this as one the core tags as it is pretty useful.

Code:

<?php 
/** 
 * Smarty plugin 
 * @package Smarty 
 * @subpackage plugins 
 */ 


/** 
 * Smarty first_sentence modifier plugin 
 * 
 * Type:     modifier
 * Name:     first_sentence 
 * Purpose:  trim a string to the first sentence 
 * @link http://www.phpinsider.com/smarty-forum/viewtopic.php?t=10170 
 * @author   Boots 
 * @param string 
 * @return integer 
 */ 
function smarty_modifier_first_sentence($string) 
{ 
    // find periods with a word before but not after. 
    preg_match('/^.*[^\s]\.(?!\w)/U', $string, $match); 
    return $match[0]; 
} 

/* vim: set expandtab: */ 

?>
