Hi guys this is my first post on wpcult the great site Austin built.  Hope you guys find it usefull.

If you run a blog using the wordpress software then your blog is a target to hackers.  Below I will list some hacks and just how they can help you keep your business/site safe.

The following is  code to Block Bad Queries and protect your blog from malicious URL Requests.

Place the following code into a text file and name it what ever you like for example blockbadqueries.php upload it to your plugin folder and activate it in your wordpress admin just as you would any other Plugin

<?php
/*
Plugin Name: Block Bad Queries
Plugin URI: http://perishablepress.com/press/2009/12/22/protect-wordpress-against-malicious-url-requests/
Description: Protect WordPress Against Malicious URL Requests
Author URI: http://perishablepress.com/
Author: Perishable Press
Version: 1.0
*/
global $user_ID; if($user_ID) {
  if(!current_user_can(‘level_10’)) {
    if (strlen($_SERVER[‘REQUEST_URI’]) > 255 ||
      strpos($_SERVER[‘REQUEST_URI’], “eval(“) ||
      strpos($_SERVER[‘REQUEST_URI’], “CONCAT”) ||
      strpos($_SERVER[‘REQUEST_URI’], “UNION+SELECT”) ||
      strpos($_SERVER[‘REQUEST_URI’], “base64”)) {
        @header(“HTTP/1.1 414 Request-URI Too Long”);
 @header(“Status: 414 Request-URI Too Long”);
 @header(“Connection: Close”);
 @exit;
    }
  }
}
?>

 This Great plugin was made by Jeff Starr of Digging into WordPress

 

 

Protecting your blog with .htaccess 

.htaccess files have lots of possibilities. below is some code that will help protect your wordpress from modification of _REQUEST and/or GLOBALS and scripts injection.

 This is real simple just paste the following code into your .htaccess file. Always make a backup of your .htaccess before editing, better to be safe.

Options +FollowSymLinks
RewriteEngine On
RewriteCond %{QUERY_STRING} (\<|%3C).*script.*(\>|%3E) [NC,OR]
RewriteCond %{QUERY_STRING} GLOBALS(=|\[|\%[0-9A-Z]{0,2}) [OR]
RewriteCond %{QUERY_STRING} _REQUEST(=|\[|\%[0-9A-Z]{0,2})
RewriteRule ^(.*)$ index.php [F,L]

 

Thanks to Oussama for this great hack

    It’s not a very secure place, the internet, is it?! I can’t believe how much trouble I have to go to as a blogger to ensure everything is a) working and b) secure!

    Ah well!

    GREAT POST! Seriously.. I recently had a few sites down due to very similar issues. I think it was automated SQL Injections from the looks of things.. Anyhow – strong first post and good information to boot.

    Nice first blog post. Internet security in general is often overlooked as unneccesary. This is a fatal mistake, and WordPress users can fall foul of prey!

    More people need to know how to configure their .htaccess files. As a matter of fact, I just compared your recommended settings to my own – I need to make a few tweaks. Thanks for the informative article.

    Wow.. useful to know, I had no idea that there was this kind of issue with WP. I once had a script injection attack on a regular html web site I was running, and my web host gave me a javascript to put in the site which would protect it from those kinds of events in the future. I don’t quite understand all the terms you use – what’s a ‘malicious URL request’? Is that an automated request sent by a bot?

    This is something dangerous and can be very harmful for the wordpress users. I think wordpress should be careful about it otherwise it can have serious security problem.

    I’m constantly worried about securing my wordpress. I use the bad behavior plugin which I think is similar to the plugin in your post. I see hack attempts in my log files all the time but so far I think so good.

    WordPress needs no introduction because it is currently creating lots of waves on the internet at the moment. Some people had gotten their fingers burnt by activities of some online criminals that specialize in stealing information that are in other peoples’ sites and blogs.

    You must have the latest version of WordPress if you want to be protected. This plugin seems to be very easy to use. However I prefer the protection made from the .htaccess file, exactly like in this tutorial.

    You state that this code is to “block bad queries”. What exactly does that mean? How do you define a “bad query”?

    I know this thread is getting old now but WordPress hacking is still a real issue. We have a large number of sites built on WordPress and many of them have been hacked as recent as the last 2 weeks. Real bad hacks as well with the database wiped and everything. It’s a pain because WordPress is such a great platform to use and very popular with our clients – they love the easy CMS. Wish we could fix WordPress hacking once and for all…!

How to: Add a contact me via Skype™ button

Published

August 2, 2025

This little trick is really simple and easy. All you need to do is plug this line of code anywhere you would like to use the text.

<a onclick="return skypeCheck();" href="skype:austin.passy?call">Call me on Skype!</a>

That’s is, pretty simple huh? Just make sure you change skype:austin.passy to your user name!

Want a test? Well, please use the text button, as I was getting to many call’s and hangups: Call me on Skype! Message me on Skype!

Thanks to Shayne for this code!

Update:

I was reminded by Shayne that you will have to add this script into your header.php file:

<script type="text/javascript" src="http://download.skype.com/share/skypebuttons/js/skypeCheck.js">
</script>

That way if the user doesn’t have Skype, they will be prompted to download it if they would like :).

How to: show/hide a widget in WordPress with jQuery

In a previous post I talked about how to show/hide a single div html code with a search inside. Today I’d like to show you how I implemented jQuery into my new theme.

Published

2 weeks ago

on

July 25, 2025

By

As seen in the current theme, I am using jQuery to animate the show/hide or as known as the css style display: none;.

Since I am using a custom child theme on my site, and have Hybrid theme as my parent, the widgets or sidebar section is different than may be in your theme. But just apply the the style’s as follows to your theme.

First make sure that your WordPress site is calling jQuery, by plugging in this code into your header.php file above the <?php wp_head(); ?> text:

<?php wp_enqueue_script('jquery'); ?>

Then anywhere above the </head >, plug this code in:

<script type="text/javascript">
function toggleWidgets() {
	$('#primary h3.widget-title').addClass('plus');

	$('#primary h3.widget-title').click(function() {
		$(this).toggleClass('plus').toggleClass('minus').next().toggle(180);
	});

}
$(document).ready(function() {
	toggleWidgets();
}
</script>

That’s it. Pretty simple huh.

So lets go over what the code does.

$('#primary h3.widget-title').addClass('plus');

This line finds all <h3> tags with the class widget-title inside the ID parameter of #primary and adds a class of plus.

Then

$('#primary h3.widget-title').click(function() {
		$(this).toggleClass('plus').toggleClass('minus').next().toggle(180);
	});

Will apply a click function. When the H3 tag is clicked it will remove the class plus and add the class minus.

Then the code that says .next will then toggle the “next” element after the <h3> title.

Don’t know PHP that well?

Well here is a simple way to add a share script like fbshare.me to your site, via shortcodes.

Paste the following code in your functions.php file in order to create your shortcode:

function fbshare_script() {
     return '<div class="fbshare"><script src="http://widgets.fbshare.me/files/fbshare.js"></script></div>';
}
add_shortcode( 'fbshare', 'fbshare_script' );

Once done, you can display the facebook share button anywhere on your posts. In WordPress editor, make sure you are in HTML mode and insert the following: [fbshare].

When your post will be published, the shortcode will be replaced by the fbshare.me button.
