I have a customized template that I am using and I am trying to get post from just one category to show on the front page. The code that is there looks like this:
<?php if (Themehave_random_posts()) : ?>
<?php while (Themehave_random_posts()) : $theme_queryRandom->the_post();
if(!@in_array(get_the_ID(), $showedPosts)){?>What would I change to control the category?
That's a custom function (i think), refer to your theme's functions.php.

Looking in functions I found this....`function Themehave_random_posts(){
global $wp_query, $shortname, $theme_queryRandom, $wpdb, $cx, $showedPosts, $ids;
if(!$theme_queryRandom){
$show = (int)get_settings($shortname."_randomCategoryPosts");
if(!in_array($show, $ids))
$ids[] = $show;
$theme_queryRandom = new WP_Query('category_name='.get_cat_name($show).'&orderby=rand&showposts=1');
}
$aux = $theme_queryRandom->have_posts();
if(get_the_ID())
$showedPosts[] = get_the_ID();
return $aux;
}`
Now Im more confused.
This part is a custom query...
WP_Query('category_name='.get_cat_name($show).'&orderby=rand&showposts=1');
You should, and i say 'should' be able to just edit that line to read...
WP_Query('category_name='.get_cat_name($show).'&orderby=rand&showposts=1&exclude=1,2,3');
Example above excludes categries 1, 2 and 3, if you wanted to exclude category 38 for example you'd do...
WP_Query('category_name='.get_cat_name($show).'&orderby=rand&showposts=1&exclude=38');

When I exclude the categories I dont want I get this error
Fatal error: Call to undefined function themehave_random_posts() in /backup/taaluxur/public_html/homes/wp-content/themes/freshblue-idea-10/home.php on line 6
It works if that change is not made though?
The error suggests that it does not recognise the custom function.

Yes, it works fine. line 6 is of course the intial code in post. Does something need to be changed there too for these to work together?
Perhaps you'd be better with creating a custom query.

Not sure how it would mesh with your custom template, but would a plugin work for you? Advanced Category Excluder lets you exclude categories from pages.

I appreciate the links but they coding examples are over my head. Ill try to plug in. But since this is semi custom code I doubt it would work.
