WordPress Hacks – How to Remove Date from Posts

WP Themes — Sat, 13 Jun 2009 07:53:32 +0000

If you want to remove date from appearing on your blog posts, just delete the following snippet of codes from the /wp-content/themes/index.php page.

1
2
3

If your theme has single.php, page,php, archives.php, find the codes and delete them too. As always, please make a backup of your files before deleting/editing anything.

On this site, we have the date displayed. But there are cases when you don’t want to display the date.

Display Today’s Date on your Blog

Want to show the date on your WordPress blog just anywhere? Well, here’s a simple little hack with just a little bit of code that you can place anywhere for the date to be shown.

Here’s that code, and you can place it anywhere that suits your needs:

You can futher format the date, but that seems like a little too much for me to get into. You can check out further documentation on that at the official php website.

Display the Author Who Edited a Post Last

Want to display the author who last edited any given post? Well, here’s some simple code you can use to have that show on all of your posts.

To first create the function for the task that we are going to do, copy and paste the following code into your theme’s functions.php file:

if (!function_exists('get_the_modified_author')) {
  function get_the_modified_author() {
    global $post;
    if ( $last_id = get_post_meta($post->ID, '_edit_last', true) ) {
      $last_user = get_userdata($last_id);
      return apply_filters('the_modified_author', $last_user->display_name);
    }
  }
}

if (!function_exists('the_modified_author')) {
  function the_modified_author() {
    echo get_the_modified_author();
  }
}

If you know what all of that mumbo-jumbo (php) means, then you should know that it’s as simple as pasting:

anywhere you want for the modified author of any given post. Just make sure that you put that code within you’re WordPress theme’s loop somewhere.

How to Get the Word Count in a Post

Keenan Payne — Tue, 07 Apr 2009 14:59:10 +0000

Thanks to WPRecipes, I have found an amazingly helpful tutorial how to get the word count in a post to show up on your index, or on your single page if you prefer. Here’s how we go about doing this.

Okay, first, open up your functions.php file in your themes directory, and paste the following code anywhere within:

function count_words($str){ $words = 0; $str = eregi_replace(" +", " ", $str); $array = explode(" ", $str); for($i=0;$i < count($array);$i++) { if (eregi("[0-9A-Za-zÀ-ÖØ-öø-ÿ]", $array[$i])) $words++; } return $words; }

Then, open up whereever you want the word count for your post to show up, be it the index.php or single.php, and paste this code anywhere within it:

Word count: post_content); ?>
And voila! The word count for your posts will be displayed!

How to Number Your Comments

Lets say you have a fairly popular blog, but you want to follow the discussions that go on in the comments section. Instead of depending on that small avatar to find where you posted, here is an easy way to number all of the comments made on a post. I have included this on my blogs, and it has been very well accepted by readers and users. Here’s how we will achieve this simple hack:

Open up your comments.php file, and find this line:

Then, put this code above what you just found:

It’s as simple as that. As far as I know this works with the new threaded commenting system in WordPress 2.7+, but if you have any problems, please leave a comment and I’ll see if I can fix it.

Thanks to Pro Blog Tutorials for this simple hack

How to Add the Author’s Gravatar in Posts

Keenan Payne — Thu, 26 Mar 2009 01:24:24 +0000

There are tons of sites out there that will use avatars along with usernames when displaying posts. On a WordPress blog, the easiest way to do that is by using gravatars. This is a site that is run by Automattic, and you can upload an avatar, that is then attached to your email address. This little hack will show your avatar to people on your site, but only if you are using the same email for your gravatar account and WordPress acount.

Just place this code in your index.php, and single.php, where you want the avatar to be displayed:

And it’s as easy as that!

How to Make Header Images Random

So you want to make the header images on your blog random huh? Well, you can do this extremely easy. Here are the steps to achieve this simple task.

1) Get the Images

Okay, get 4 images that you want to use on your blog. Here’s what I’ll be using:

header1.jpg

header2.jpg

header3.jpg

header4.jpg

Put all of these images in a folder called images in your theme folder. If you don’t have that folder yet, go ahead and create one now.

2) Randomizing the Images

Put this code in your header.php file just below the tag:

$header_image = rand(1,4); ?>

So if you more or less images, you can change 4 to whatever it is.

3) Randomizing in the Header

If you’re using a more professional WordPress theme, then more than likely the header image is going to be called in from the .css file using a header DIV. Well, you’re going to have to get rid of that, and use this old-school HTML technique.

Use this code to pull the header images into your theme:

/images/blogtop-.gif" alt="header" />

So that concludes our random header image tutorial for WordPress. You can pretty much use the same technique, but modify it a little bit, if you want to use this on a static HTML/CSS website, a forum, or maybe even another CMS!

How to add an “edit” link to all of your WordPress Posts

Keenan Payne — Fri, 20 Mar 2009 00:38:35 +0000

Sometimes you look at a post that you or a fellow author has published, and you see a little typo. Well, while you could go from there, to the admin dashboard, and then to the edit page, and then find the page, well, that’s just not much fun now is it? Well, here is a simple little design hack that you can use to have an edit link be posted on every post made on your blog so you can do those quick-edits anytime you need to.


    Edit Post

The current_user_can() function checks the level of the current user if you are logged in, and if you have sufficent permissions, then you can edit the post. I’m going to assume that you don’t want anybody that’s below an administrator to edit a post, so we are going to use current_user_can(’level_10′) to make sure that only administrators can edit said post.

You can change that to whatever you want, and what permissions the user must have to edit a post.

How to widgetize a WordPress blog theme

Keenan Payne — Wed, 18 Mar 2009 02:12:18 +0000

Okay, if you’re new to WordPress, more than likely all of the themes you are looking at using are widgetized. For that special occasion that your WordPress blog theme isn’t widgetized, here’s a simple way of how to hack your theme, and with just a little bit of code, you can widgetize your theme.

Here’s what the official page from Automattic says:

Instead of register_sidebar() you should use register_sidebars(n) where n is the number of sidebars. Then place the appropriate number in the dynamic_sidebar() function, starting with 1. (There are several other ways to use these function. See the API). You can even give your sidebars names rather than numbers, which lets you maintain a different set of saved sidebars for each theme.

You edit this in the functions.php file. If you don’t have a functions.php file, then you probably don’t have a widgetized theme. Here’s an example of some code that you could put in your functions.php file:

if ( function_exists(’register_sidebar’) )
register_sidebar();
?>

Then, right beneath the

|| !dynamic_sidebar() ) : ?>

Then, right above the closing

tag, put this code:

Pretty simple huh? Now that old-school WordPress theme that you are using is completely widgetized and customizable!
