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

    When I had my hosting company, one of my client’s blogs kept getting hacked. I fixed it a half a dozen times before told him that he has to fix his own issues – pointed him to posts like this around the internet.

    Good stuff!

Creating a custom widget

Published

September 1, 2025

By

Today let’s learn a simple quick trick on how to create a custom widget. For my example I will show you how I created my Showcase widget located in the middle, to the right of the posts.

First under your functions.php file type in the following:

<?php // Custom Widget
function MyCustomWidget() { ?>
<li class="widget">
    <h2 class="heading">Latest Showcase</h2>
        <ul>
        	<?php include(TEMPLATEPATH . '/includes/showcase.php'); ?>
        </ul>
</li>

<?php }

register_sidebar_widget('The Custom Widget for Showcase', 'MyCustomWidget'); ?>
  • Always make sure your code is between the <?php and ?> for it to work.
  • Once we call the function, the rest is assuming html code that you may or may not need.
  • For instance, you may just put in a picture and call it a day. But my code starts with <li< because my sidebar’s start and end with <ul<.
  • Any way, once your done, just set the final “register_sidebar_widget('the widget title', 'the name of the function');“

That’s it! Now you have a custom widget with what ever you want!

Display custom url if comment authors url is blank

Here is a nifty trick for your comments.php template. If someone comes to your site and leaves a comment but doesn’t leave a url back to there site, the default link that is shown in place of the php code comment_author_url is the current page link.

That might not look good. So, here is a little trick that I just implemented into my site. Besides installing the twittar plugin and pulling Twitter avatars I wanted to use the image itself for the authors url like. But if the author doesn’t have a Twitter avatar or a Gravatar it will display a default Gravatar that I set. If the default Gravatar is shown, usually the author will not leave a url link.

I would like to link the image to Gravatar.com so that they can get an image attached to their email address. So.. here is the code:

<?php if($comment->comment_author_url != "") { ?>
<a href="<?php comment_author_url(); ?>"><?php gravatar(); ?></a>
<?php } else { ?>
<a href="http://gravatar.com" title="Get a Gravatar today!"><?php gravatar(); ?></a>
<?php } ?>

Echo custom fields in any category

Published

Here is a neat trick. Say you want to show a custom field in you post or in a certain categories post. There is a simple code you need to write in order to accomplish this:

<?php $image = get_post_meta($post->ID, "image", $single = true); ?>
<?php if($image != '') : if(in_category(7)) { echo ''; } else { ?>
<img src="<?php echo $image ?>" alt="<?php the_title(); ?>" /></a>

In the example above I am calling the variable $image and telling the server that it equals the value of “image” inside get_post_meta or “custom field” of the current post.

Then we are asking if that variable $image doesn’t equal nothing or != and if it is in the category id of 7, echo what ever is in the single quotes (which is nothing in this example), otherwise show the <img> and the value inside “image” which should be the location of the image.

Update: Thanks to Austin from PressedWords for pointing out his trick, from the comment below.
