Hey there guys.

Ok thing is I really suck at php and I'm trying to exlude a post, or possible a category, either one would work, from a random post widget I have.

If you check out the site you can see the widget on the right side (random paranormal movies) is displaying my sticky welcome message at the top.

I know the category id and post id and have tried a few things to no avail.

Anyway any help would sure be welcome:

<?php

/*

Plugin Name: Simple Random Posts Widget

Plugin URI: http://infobak.nl/si...for-wordpress//

Version: 1.26

Description: Widget which displays random posts

*/

define("DefNoOfPosts", "5"); // default number of random posts to display

class SimpleRandomPostsWidget extends WP_Widget {

function SimpleRandomPostsWidget()

{

parent::WP_Widget( false, 'Simple Random Posts', array('description' => 'Random posts widget') );

}

function widget($args, $instance)

{

global $NewSimpleRandomPosts;

$title = empty( $instance['title'] ) ? 'Simple Random Posts' : $instance['title'];

echo $args['before_widget'];

echo $args['before_title'] . $title . $args['after_title'];

echo $NewSimpleRandomPosts->GetSimpleRandomPosts( empty( $instance['ShowPosts'] ) ? DefNoOfPosts : $instance['ShowPosts'] );

echo $args['after_widget'];

}

function update($new_instance)

{

return $new_instance;

}

function form($instance)

{

?>

<p>

<label for="<?php echo $this->get_field_id('title'); ?>"><?php echo 'Title:'; ?></label>

<input type="text" name="<?php echo $this->get_field_name('title'); ?>" class="widefat" id="<?php echo $this->get_field_id('title'); ?>" value="<?php echo esc_attr($instance['title']); ?>" />

</p>

<p>

<label for="<?php echo $this->get_field_id('ShowPosts'); ?>"><?php echo 'Number of entries:'; ?></label>

<input type="text" name="<?php echo $this->get_field_name('ShowPosts'); ?>" id="<?php echo $this->get_field_id('ShowPosts'); ?>" value="<?php if ( empty( $instance['ShowPosts'] ) ) { echo esc_attr(DefNoOfPosts); } else { echo esc_attr($instance['ShowPosts']); } ?>" size="3" />

</p>

<?php

}

}

class SimpleRandomPosts {

function GetSimpleRandomPosts($noofposts)

{

rewind_posts();

query_posts('orderby=rand&showposts='.$noofposts);

if (have_posts()) :

echo '<ul>';

while (have_posts()) : the_post();

echo '<div id="post-'.get_the_ID().'"><li><a href="'.get_permalink().'">'.get_the_title().'</a></li></div>';

endwhile;

echo '</ul>';

endif;

wp_reset_query();

}

}

$NewSimpleRandomPosts = new SimpleRandomPosts();

function SimpleRandomPosts_widgets_init()

{

register_widget('SimpleRandomPostsWidget');

}

add_action('widgets_init', 'SimpleRandomPosts_widgets_init');

?>

Use the minus "-" sign when assigning ID's in the WP_Query array.

Example

<?php $query = new WP_Query( array( 'post_type' => 'post', 'post__not_in' => array( 2, 5, 12, 14, 20 ) ) ); ?>

Those ID's in the array of "post__not_in" are what can be generally excluded.

All of your custom querying options are on this page in the WordPress Codex.

Thanks again mate for the help.

What is confusing me though is that does the plugin which the original code is from write into the query file? Do I have to go into the query.php file and make the changes in there or can i make them in the original plugin file?

Sorry man you got me a little lost here. Coding has never been my strong suit.

no the plugin is using wp_query (query.php)

just edit the code directly, edit the plugin.

Either from the files or admincp>plugins>edit

The code I posted is from the plugin.

I also can't find any obvious place where I could stuff the exlude or that is the -.

You think I might have to include the line he mentioned before inside the code:

<?php $query = new WP_Query( array( 'post_type' => 'post', 'post__not_in' => array( 2, 5, 12, 14, 20 ) ) ); ?>

Replace:

query_posts('orderby=rand&showposts='.$noofposts);
with:
query_posts(array('orderby' => 'rand', 'posts_per_page' => $noofposts, 'post_not_in' => array(2,5,12,14,20) ) );
