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

    Thanks for that.

    Wanted to say, people nowadays who are using scripts that are bought or available for free, completely ignore the fact that these scripts might actually be vulnerable, and think they are not because some company makes them.

    A successful webmaster should always put security on the top of his priorities, update his software and check it for vulnerabilities regularly.

    Welcome Miguel! Your first post is a goodie, and what better subject to look at than security. If you leave the back door open you may turn around to find the pantry empty! Nobody deserves that, and paying attention to your security at home as well as on your website is a must to prevent unauthorized access and subsequent damages or losses.

    I’ll keep my eyes open for future posts from you. Enjoy, and good luck with your blogging. Writing is inspiring and sharing your knowledge with others is very gratifying.

    Hi!

    My Blog was hacked a few months ago. This deleted my footer.php and instead I got a footer.php with only invisible Spamlinks in it.
    I don’t know how long this file has been on my blog because it didn’t attract any attention from me. Who takes daily care about his page footer?

    So my question: are the above mentioned queries the only one which can cause problems?

How to: Add a contact me via Skype™ button

Published

on

August 2, 2025

By

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

1 week 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.
