Multiple instances of nivo slider plugin

Question

I’m using Wordpress as a CMS for this site

http://www.seadragon.co.uk/new_site/portfolio.html

...and it’s the first time I’ve ever used wordpress so sorry if I get the terminology wrong....

My client needs to be able to add new projects (case studies) to the portfolio section, and each of them can have it’s own slideshow.

I thought they could create a new post category for each project slideshow, and then a new page for each project.

The problem I have is how to get my client to associate the post category with the project page (so I can pull the correct category posts in to the slideshow dynamically). I thought maybe I could try and get them to use the same naming convention for the category she creates (for the project sildeshow) and the page she creates (for the project)? Does this sound like it’ll work? Is there a better way I can do this, or another plugin that would be better suited.

Here’s the code from my portfolio template... currently the categoryID is hard coded in the query.

<div id="slider">
            <?php
            //Reset Query
            //wp_reset_query();
            global $wp_query;
            $query = "post_type=post&cat=5";
            $wp_query = new WP_Query( $query );

            if ( have_posts() ) : while ( have_posts() ) : the_post(); 

                echo get_the_post_thumbnail($post->ID, 'large');
                ?>

            <?php 
            endwhile; endif;
            ?>
              </div>

            <script type="text/javascript">
            $(window).load(function() {
            $('#slider').nivoSlider();
            });
            </script>

Hope that makes some sense?

Many thanks.

A better solution would be to create a "Project" post type and a custom taxonomy to separate the different types of projects.

I recently did this on my own website because I wanted a way to keep my projects separate from the rest of my content. I used jQuery cycle instead of Nivo but the concept is the same.

Custom post types have a built in user interface so it wont be confusing for your client to add new projects.

It will also allow you to customize the way the "Projects" are displayed using a single-project.php template file.

I won't go into how to register post types because The Codex explains this very well but I will show you how to get all the attached images to the post and display them in the slider.

<?php   
//The following code is for a sample single-post_type.php
?>
<?php get_header(); ?>
<div id="content">

<?php if (have_posts()) : while (have_posts()) : the_post(); ?>
    <div id="post-<?php the_ID(); ?>" <?php post_class(); ?>>
        <h1 class="project-title"><?php the_title(); ?></h1>
        
        <div class="entry">
            <div id="slider">
        
                <?php
                // This gets all the images attached to the current post inside the loop
                    $args = array(
                    'post_type' => 'attachment',
                    'posts_per_page' => -1,
                    'post_status' => null,
                    'post_parent' => $post->ID
                    ); 
                $attachments = get_posts($args);
                if ($attachments) {
                    foreach ($attachments as $attachment) {
                 
                echo wp_get_attachment_image($attachment->ID,'medium', false);
                }
                    } ?>

            </div> <!-- /slider -->
            
        <?php the_content(); ?>
        
    </div> <!-- /post -->   

    <?php endwhile; else: ?>
    <p><?php _e('Not Found','your_theme_name'); ?></p>

    <?php endif; ?>
    
</div>
<?php get_sidebar(); ?>
<?php get_footer(); ?>
