Conditional comments for the length of a post (4 posts)

    I would like to include extra content alongside each post based on the length of the post, i.e. if a post is under 500 characters, show a short banner. If it's over 500, show a medium size banner. And if it's over 1000 characters, show a long banner, etc.

    My site is http://dotneil.com . I plan to put this additional content in the <dl> to the left of each post - so it will be in the Loop. I'm okay with conditional comments for pages, sidebars etc, i.e. <?php if(is_single())?> etc, but I don't know how to make conditional comments work via queries against the length of a post.

    I think this would make quite a handy plugin if it had a simple interface for choosing the character increments (i.e. 500 words) and the content rendered at each increment, especially if it's implemented in the traditional sidebar via a widget...or maybe this plugin exists and I just don't know about it!?!

    On my WordPress site, I've borrowed some code from The Engineered Boulderer’s Word Count Plugin. Define this function once anywhere before you want to use it:

    <?php
    function word_count($display = false) {
        global $wpdb, $id;
    	$post = $wpdb->get_var("SELECT post_content FROM $wpdb->posts WHERE ID = $id");
    	$post_content = apply_filters('the_content', $post);}
    	$words = trim(strip_tags($post_content));
    	if( $words == '' ) {
    		$wordcount = 0;
    	} else {
    		$words = explode(' ', $words);
    		$wordcount = count($words);
    	}
    	if( $display ) {
    		echo $wordcount; }
    	else {
    	return $wordcount; }
    } ?>

    I use it to customize the size of the font, depending on how long the post is. Shorter posts get a lot more balance that way. I'm sure you could adapt my code for your purposes:

    <?php if(function_exists('word_count')) {
    	$words = word_count();
    	if (200<$words && $words<=240) echo 'style="font-size:98%"';
    	elseif (240<$words && $words<=285) echo 'style="font-size:97%"';
    	elseif (285<$words && $words<=360) echo 'style="font-size:95%"';
    	elseif (360<$words) echo 'style="font-size:94%"';
    }
    ?>

    Wow. Neat idea.

    I would like to try making different sidebars depending on length of post. That would be pretty cool to help prevent a short post -- long sidebar appearance.
