Adding more and more plugins can bloat out your WordPress installation, so one alternative is to use straight coding. You can customise your WordPress blog and add new features without worrying about plugins, widgets and themes using these simple code snippets. If you don’t have a WordPress blog yet, check out our one-click WordPress<\/a> install, or sign up for web hosting or reseller hosting.<\/p>\n

Display Random Links<\/h4>\n

If you have a lot of links to other websites and not very much space, you can show random links in your WordPress sidebar rather than displaying all of them at once. To do this, open up your sidebar.php file (either in the WordPress theme editor or via FTP). Then define your existing list to show random links by using \u2018rand\u2019 in the tag, e.g.<\/p>\n

<\/p>\n

<?php wp_list_bookmarks('limit=10&orderby=rand'); ?><\/p>\n

<\/code><\/p>\n

You can change the \u201810\u2019 to the number of links you want to display.<\/p>\n

Block other IPs from the admin area<\/h4>\n

This handy snippet will only allow static IP addresses of your choosing to access the admin directory. Just make sure that you plan ahead if you change blogging locations a lot. It\u2019s ideal for extra protection against hackers, and can be used for multi-user blogs as well.<\/p>\n

1.Using FTP, open your \/wp-admin\/ folder and find the .htaccess file (if you don\u2019t have one, upload an empty .txt file and rename it to .htaccess \u2013 don\u2019t edit the one in your root WordPress folder).<\/p>\n

2.Paste the following code:<\/p>\n

AuthUserFile \/dev\/null<\/p>\n

AuthGroupFile \/dev\/null<\/p>\n

AuthName “WordPress Admin Access Control”<\/p>\n

AuthType Basic<\/p>\n

 <\/p>\n

<\/p>\n

order deny,allow<\/p>\n

deny from all<\/p>\n

# whitelist Admin’s IP address<\/p>\n

allow from xx.xx.xx.xxx<\/p>\n

# whitelist User 1’s IP address<\/p>\n

allow from xx.xx.xx.xxx<\/p>\n

# whitelistUser 2’s IP address<\/p>\n

allow from xx.xx.xx.xxx<\/p>\n

 <\/p>\n

<\/LIMIT><\/p>\n

<\/code><\/p>\n

Include any IP addresses where the x\u2019s are and remove\/add extra lines as you wish, then save the file. To give anyone else access to the admin panel in the future, you\u2019ll have to go into the .htaccess file again and add them manually.<\/p>\n

Customise the logo on your WordPress login page<\/h4>\n

Bored of the same WordPress logo on the login screen? Change the image to anything you like with this snippet. It\u2019s particularly good to make your login screen more consistent with your website\u2019s design or company image and adds more interest to multi-user blogs. If you manage multiple blogs, changing the logo is also helps identify them instantly.<\/p>\n

Open function.php and include this code, then change \/images\/custom-login-logo.gif to the URL of your image.<\/p>\n

function my_custom_login_logo() {<\/p>\n

echo '<\/p>\n
