Question

I'm having some problems setting up Number of posts to show on Home Page. When I set the Number of Posts to show in theme options it reverts back to 3. I want to change the number of posts from 3 to 5.

Here is the code block on my home.php which I think needs a bit refinement.

-->

  <?php $recent = new WP_Query("cat=".get_theme_mod('featured_top_left')."&showposts=".get_theme_mod('featured_top_left_num')); while($recent->have_posts()) : $recent->the_post();?> <?php if( get_post_meta($post->ID, "thumb", true) ): ?> <a href="<?php the_permalink() ?>" rel="bookmark"><img class="thumb" src="<?php bloginfo('template_directory'); ?>/tools/timthumb.php?src=<?php echo get_post_meta($post->ID, "thumb", $single = true); ?>&amp;h=<?php echo get_theme_mod('featured_top_left_thumb_height'); ?>&amp;w=<?php echo get_theme_mod('featured_top_left_thumb_width'); ?>&amp;zc=1" alt="<?php the_title(); ?>" /></a> <?php else: ?> <?php endif; ?>

According to Wordpress Manual :

showposts (int) - number of post to show per page. Deprecated as of Version 2.1 in favor of 'posts_per_page'.

So , if you're version is >2.1 you should edit the code and replace showposts with posts_per_page in the WP_Query .

        <?php $recent = new WP_Query("cat=".get_theme_mod('featured_top_left')."&posts_per_page=".get_theme_mod('featured_top_left_num'));

UPDATED CODE.
