WP-DenyHost

This is a plugin that will block a spammer if he already has been tagged as a spammer. I use it together with the Akismet plugin. Akismet tags the spammer, and wp-denyhost prevents him from adding more comment spam.

Core functionality :

define('PS_DENYHOST_THRESHOLD', 5);
function ps_denyhost() {
    global $wpdb;

    $suspect = $this->get_IP();
    $count = (int) $wpdb->get_var("SELECT COUNT(comment_ID) FROM $wpdb->comments WHERE comment_approved = 'spam' AND comment_author_IP = '$suspect'");

    if ($count > PS_DENYHOST_THRESHOLD) {
        exit;
    }
}
add_action('init', 'ps_denyhost');

Download / install: http://wordpress.org/extend/plugins/wp-denyhost/

Sandbox Skin Editor

Note: This is work in progress, when the editor is done, it will be announced here.

I’m coding a skin editor for the sandbox theme. The code will be gpl, so you can adjust it to other themes, but I will only support the sandbox theme.

Here’s a demo of the prototype: http://soderlind.no/demo/skineditor.php

v1.0 will:

  • support both WordPress 2.x and MU
  • have a preview
  • allow you to save a style to a temporary file prior to publishing it (for testing)
  • in MU, save the style to wp-content/blogs.dir/$wpdb->blogid/css
  • filter the saved css to prevent xss

btw, if you don’t know the Sandbox theme, have a look here: http://www.plaintxt.org/themes/sandbox/. It is one of the easiest/best themes to use as a building block for creating your own themes using css.

    }

    if ($rs['items_count'] < = 0) {
        echo "Sorry, no items found in the RSS file :-( "; }
    } else {
        echo "<!-- It's not possible to reach RSS file -->";
    }
}

GeoIP

This plugin might exist allready, but I couldn’t find it using google, so here it is

The plugin gives you four functions you can use in your blog:
get_geoip_country_code and get_geoip_country_name returns the the visitors country code / name

the_geoip_country_code and the_geoip_country_name echos the the visitors country code / name

INSTALLATION:

1) Extract the plugin into your WordPress plugins directory.

2) Download the free GeoIP country database from MaxMind , and extract it into your plugins/GeoIP directory

3) Optional, If you need country flags, you’ll find them here: http://www.maxmind.com/download/geoip/database/flag.zip

4) Activate it on the Plugins tab of the WordPress admin console.

SAMPLE USE:

<img src="/flag/<?php echo
strtolower(get_geoip_country_code())?>.gif" alt="<?php
the_geoip_country_name()?>" />

NOTE, If you have full access to your server and it’s running Apache, you should take a look at the mod_geoip
