mod_latestnews : limited number of characters from the topic title

[ArXoS]

Hello Elxis

I need to edit mod_latestnews (to have a standard output wight) to limit the number of characters from the topic title that shows 
So, i changed the code (last lines)

from :

Code: [Select]

$link = sefRelToAbs( 'index.php?option=com_content&task=view&id='. $row->id . $Itemid );
?>
<li class="latestnews<?php echo $class_sfx; ?>">
<a href="<?php echo $link; ?>" class="latestnews<?php echo $class_sfx; ?>">
<?php echo $row->title; ?>
</a>
</li>
<?php
}
?>
</ul>
to :

Code: [Select]

   $link = sefRelToAbs( 'index.php?option=com_content&task=view&id='. $row->id . $Itemid );
   if (strlen($row->title) >52) {
      $title = substr($row->title, 0, 52).'...';
   } else {
       $title = $row->title;
   }
   ?>
   <li class="latestnews">
      <a href="<?php echo $link; ?>" class="latestnews">
         <?php echo $title; ?></a>
   </li>
   <?php
}
?>
</ul>
Its working great, but at the outlook, when the title is limited the last character is �... (not to all titles)
How can I avoid it ?



Thanks

If all things goes right You must use the strip_tags function.
Specifically ,

Replace the line :
$title = substr($row->title, 0, 52).'...';

with this one:
$title= substr(strip_tags($row->title),0,52).'...';

And tell me.

nope ... same results

The file must be encoded unicode UTF8  (no unicode signature BOM )
Before to save it check the properties

[ArXoS]

nope ... still same results 

[speck]

can you put the file so i check it??

There is a technique from that on mod_frondpage.php

Code: (php) [Select]

/**************/
/* LIMIT TEXT */
/**************/
public function limittext($txt, $textlimit) {
    $len = eUTF::utf8_strlen($txt);
    if ($len <= $textlimit) {
        return $txt;
    } else {
        $txt = eUTF::utf8_substr($txt, 0, $textlimit);
        $pos = eUTF::utf8_strrpos($txt,' ');
        if ($pos >0) {
        $txt = eUTF::utf8_substr($txt, 0, $pos);
    if ((($tpos = eUTF::utf8_strrpos($txt,'<')) >  eUTF::utf8_strrpos($txt,'>')) && ($tpos > 0)) {
  $txt = eUTF::utf8_substr($txt, 0, $tpos-1);
  }
}
        return $txt.' ...';
    }
}

ok, i think i got it.



i also added an option to admin panel to set the character limit


Its working, i hope it's correct

as i can see, the character length is not the one i set to admin panel. I set 60 characters length and the module returns only near the half. I guess this is because i use the command strlen instead of eUTF::utf8_strlen (as used in mod_frondpage.php)

Can someone help me finish the module with eUTF::utf8_strlen ?

Thanks

[speck]

i did some modifies and works fine.
test it!

In Elxis we use the eUTF class to handle multi-byte strings as PHP lacks of unicode support (it will be supported in PHP 6).

Instead of: substr, use eUTF::utf8_substr
Instead of: strlen, use eUTF::utf8_strlen
All the supported methods: includes/Core/utf8.class.php

As the eUTF methods are in general slow use them only when the string may contain unicode characters.

[ArXoS]

thank you elxis, the module works great. Thanks to the changes of datahell., i can set exactly the right limit with no mistakes ..

Spec, thank you too for your help. I tested your module, and it's also does the job. I placed an else parameter, because all the titles returned with dots
Thanks once more

Glad to solve this issue Arxos. Elxis has excellent unicode support many years now. By just searching Elxis core files you will find the answers to your problems as such tools are built-in.

Here is an example on how I limit strings:

$text = 'Sample text that we want to limit it down to 30 characters';
$text2 = (eUTF::utf8_strlen($text) > 30) ? eUTF::utf8_substr($text, 0, 27).'...' : $text;

$text2 has a maximum length of 30 characters (including 3 dots at the end).
