If that's not really the case and you're just counting the paragraphs then there's easier ways.</p> <p>Here's one..<br /> <pre><code>$paragraphs = explode(&#39;&lt;p&gt;&#39;,$post-&gt;post_content); $paracount = count($paragraphs); unset($paragraphs); echo $paracount; unset($paracount);</code></pre> <p>If that's not what you're attempting to do then why are you dividing the content up into an array? </p> http://wordpress.org/support/topic/281512#post-1108452 Thu, 18 Jun 2009 13:49:05 +0000 nzahn 1108452@http://wordpress.org/support/ <p>All right ... solved it; if someone is interested here is the fixed code:</p> <p>In the loop<br /> &lt;?php if ( have_posts() ) : while ( have_posts() ) : the_post(); ?&gt;</p> <p>&lt;?php $content = $post-&gt;post_content;<br /> $paragraphs = explode('&lt;p&gt;', $content);<br /> $i = 0;<br /> foreach ($paragraphs as $number){<br /> $i++;<br /> $q = $i - 1;<br /> if ($i == 0) {<br /> echo $q.$number;<br /> }<br /> }?&gt;</p> <p>&lt;?php endwhile; else: ?&gt;<br /> &lt;p&gt;&lt;?php _e('Sorry, no posts matched your criteria.'); ?&gt;&lt;/p&gt;<br /> &lt;?php endif; ?&gt;<br /> simple enough? btw. this does column splitting by &lt;p&gt; can be any tag though; hope this helps anyone. </p> http://wordpress.org/support/topic/281512#post-1108326 Thu, 18 Jun 2009 12:04:27 +0000 nzahn 1108326@http://wordpress.org/support/ <p>Well ... I am having a slight problem (of course); I am trying to filter content and explode it - it works great in 2.7 Kubrik and yes it does not work in 2.8 Kubrik; the code in its basic looks like this:</p> <p> `&lt;?php $content = apply_filters('the_content', $post-&gt;post_content );<br /> $paragraphs = explode('&lt;p&gt;', $content);<br /> $i = 0;<br /> foreach ($paragraphs as $number){<br /> $i++;<br /> $q = $i - 1;<br /> if ($i == 0) {<br /> echo $q.$number;<br /> }<br /> }?&gt;`</p> <p>the content looks like this:</p> <p>&lt;p&gt;First Paragraph&lt;/p&gt;&lt;p&gt;Second Paragraph&lt;/p&gt;</p> <p>If you do this it should not display anything - in 2.7 it behaves right; 2.8 shows content from the <code>$post-&gt;post_content</code> which makes me think that apply_filters does not do its work correctly; I tried looking it up, but nothing found in the documentation of wordpress 2.8; any help would be wonderful. Thanks upfront. </p>
