<?php 
$count = 1;
if (have_posts()) : while (have_posts()) : the_post(); if($count == 1) : ?>
<div id="featurd_post">
<div class="ftrd_image">
<?php woo_get_image('image',455,245,' '.$GLOBALS['align']); ?>   </div>
<div class="fix"></div>
<div class="ftrd_entry">
<h2 class="title">
<a href="<?php the_permalink() ?>" rel="bookmark" title=""><?php  the_title(); ?></a></h2>

&#2346;&#2338;&#2375; ', 'shreshthbharat'); ?>)</a>
</div></div>     
<?php else : ?>

<div id="post">
<div class="post_image">
<?php woo_get_image('image',455,245,' '.$GLOBALS['align']); ?>   </div>

</div></div>

please guide.

Answer 1

Try to go in a completely different way about that and this code to your functions.php

// Variable excerpt length.
function dynamic_excerpt($length) { // Variable excerpt length. Length is set in characters
global $post;
$text = $post->post_excerpt;
if ( '' == $text ) {
$text = get_the_content('');
$text = apply_filters('the_content', $text);
$text = str_replace(']]>', ']]>', $text);
}
$text = strip_shortcodes($text); // optional, recommended
$text = strip_tags($text); // use ' $text = strip_tags($text,'<p><a>'); ' if you want to keep some tags
$text = mb_substr($text,0,$length).' ...';
echo $text; // Use this is if you want a unformatted text block
//echo apply_filters('the_excerpt',$text); // Use this if you want to keep line breaks
}

Now when ever you want an excerpt in your theme use this line:

<?php dynamic_excerpt(125); ?>

125 is the length of you characters in this case...

Since this uses "mb_substr" its also great when using hebrew / arabic / chinese or any other langaues which has its characters being count differently.. so.. all around the best solution.

Hope this helps...

Answer 2

After playing with your code, I don't see any bugs with the excerpt() function.

I am guessing your problem is with your post excerpt - are you sure you have set up the excerpt for your "featured" post to be longer than 90 characters? If you haven't set an excerpt, WordPress will auto-create one for you.

If it helps, this is what I'm using: You can edit it the way you need it.

/** 
 * Sets the post excerpt length to number of words, except for some pages.
 *
 * @param int $length The current excerpt length.
 * @return int The new excerpt length in words.
--------------------------------------------------------------------- */
    function abc_excerpt_length($length) {
      // startpage
      if (is_home()) {
        return 5;
      }
      // search result page
      if (is_search()) {
        return 10;
      }
      // in the feed
      if (is_feed()) {
        return 20;
      }
      // on every other page
      return 40;
    }

    add_filter('excerpt_length', 'abc_excerpt_length');
