Need Help With Adjusting Related Posts Wordpress Plugin

[Hens00]

Hello

I have a site here (http://www.thingsaboutphones.com), which I would like to use a Related Posts plugin.

The plugin is great, but when activated it gives related posts both on the home page as well as the indidual post pages - I only want the plugin to work for indivual post pages.

Can someone show me what to remove/edit from the plugin code?:)

The code is:

<?php
/*
Plugin Name: Aizatto's Related Posts
Plugin URI: http://blendworx.com/aizattos-related-post-plugin/
Description: Returns a list of the related entries based on active/passive keyword matches.
Author: Ezwan Aizat Bin Abdullah Faiz

Try this
add_action('activate_aizatto_related_posts.php', 'aizatto_related_posts_install');
if(!is_home())
{
add_filter('wp_head', 'aizatto_related_posts_css');
add_filter('the_content', 'aizatto_related_posts_pop');
}
add_action('admin_menu', 'aizatto_related_posts_admin_menu');(put it in place of the code at the end of the plugin)

[Hens00]

Thank you Jay, I tried adding the code but unfortunately the related posts still appear on the home page as well as in the post pages?

[JAY6390]

Try changing the
if(!is_home())
to
if(!is_front_page())

[Hens00]

Sorry dude, when I changed it, I get an error message:


Fatal error: Call to undefined function s_front_page() in /home/choosemo/public_html/thingsaboutphones/wp-content/plugins/aizatto_related_posts.php on line 256

[JAY6390]

That's because you have put s_front_page instead of is_front_page (note the I before the function name)

[Hens00]

Ok I tried again using the correct code....and no luck. The plugin activates this time, but the related posts still appear.

I have been looking around for more help and have tried changing the 'frontpage' tag to 'single', and that doesnt work either :confused:

[JAY6390]

You tried
if(is_single()) not if(!is_single()) I hope. If that doesn't work, I'm not sure what's wrong sorry

[Hens00]

Ahh man I tried it with both the ! included and also without...and its the same :(

Thanks for you help anyway dude.

[JAY6390]

No probs. While I know my php, I'm not too familiar with the way wordpress implements its plugins so it was more guesswork than actual know how with the suggestions

[juust]

one german dude has one that only shows on single post-pages
http://www.rene-ade.de/inhalte/wordpress-plugin-relatedposts.html#more-168

another one might be adding an exit to the actual main function :

function aizatto_related_posts() {
global $wpdb, $post;

if(is_home()) exit;


that might do the trick.
