You’d have to run it through a filter. The hook is category_description

Example:


<?php
/*
Plugin Name: 15 Word Category Description
Version: 0.1
Plugin URI: http://txfx.net/code/wordpress/
Description: Limits the category description to 15 words
Author: Mark Jaquith
Author URI: http://txfx.net/
*/

function txfx_limit_cat_description($text) {
$excerpt_length = 15; // number of words
$text = strip_tags($text); // otherwise we could cut off in the middle of a tag
$words = explode(' ', $text, $excerpt_length + 1);
if (count($words) > $excerpt_length) { // only filter if we need to
array_pop($words);
array_push($words, '[...]');
$text = implode(' ', $words);
}
return $text;
}

add_filter('category_description', 'txfx_limit_cat_description');

?>

You should open a support ticket with your host… tell them you need a MySQL database with user/pass/db/host info.

Try Owen Winkler’s Role Manager plugin [1] and give your role the missing capabilities.

If you are getting a message telling you that you don’t have permission to do something, then it’s a permissions issue. WordPress has soles (administrator, editor, author, etc) and those roles have capabilities (edit_posts, edit_links, etc). If it says you can’t do something than your user must belong to a role that lacks the capability.

You can try the Role Manager plugin to add the necessary capabilities to your user… assuming that your user can edit_users

Some people have found that the force upgrade script I wrote fixes some permissions issues.

GPC is automatically slashed by WP. Use stripslashes() before updating the option, because update_option() will try to add slashes again.

Put this in a hacks or plugin file. Then just do <?php if (in_category_recursive_up(24)) {

It works by first checking the categories that they post has for a match. It then takes each category and “digs up” (basically asking each one, “who’s your daddy?”) until it either runs out of categories (false) or finds a match (true). I haven’t tested it too much, but initial tests indicate that it works.


function in_category_recursive_up($cat_id=0) {
if ( !is_single() )
return false;
$cats = get_the_category();
if ( !count($cats) ) // error: no cats defined!
return false;
foreach ( (array) $cats as $cat ) {
if ( $cat->cat_ID == $cat_id ) { // match!
return true;
}

if ( in_category_dig_parents($cat->category_parent, $cat_id) )
return true;
}
return false;
}

function in_category_dig_parents($cat_id, $look_for) {
if ( !$cat_id )
return false;
if ( $cat_id == $look_for )
return true;
$cat = get_category($cat_id);
return in_category_dig_parents($cat->category_parent, $look_for);
}

Right after the first wp_mail() call, put this:


wp_mail(get_option('admin_email'), $subject, $defaultmessage, $headers);
