Assign an image to post ID
This snip assigns an image to each unique post ID from Wordpress, which in this case I have made a gif. If you put a file in the image folder in your root directory of your Wordpress install called 8.gif – the 8th post you made on your blog will be assigned that image wherever you place this code. If there is no image for that id (you haven’t put a file called 8.gif in yet) it assigns the image called logo.gif. You can change any of the directories, file extensions, and the alternative image name to suit your own needs. You can find the post ID by looking in manage posts from your dash. You should use this code in template files.
<?php
$image = “$id.gif”;
if(is_readable(“./images/$image”))
{
echo “<img src=’/images/$image’ alt=’alt tag’ />”;
}
else
{
echo “<img src=’/images/logo.gif’ alt=’alt tag’ />”;
}
?>
To Separate the Trackbacks
Open comments.php, and search for the following line:
<?php foreach ($comments as $comment) : ?>
After it, paste the following:
<?php $comment_type = get_comment_type(); ?>
<?php if($comment_type == 'comment') { ?>
Now look for:
<?php endforeach; /* end for each comment */ ?>
And before it, paste:
<?php } /* End of is_comment statement */ ?>
This will display your comments without any trackbacks or pingbacks. To add a second comments loop for the trackbacks.
Look for the following line:
<?php else : // this is displayed if there are no comments so far ?>
And before it, paste this:
<h3>Trackbacks</h3>
<ol>
<?php foreach ($comments as $comment) : ?>
<?php $comment_type = get_comment_type(); ?>
<?php if($comment_type != 'comment') { ?>
<li><?php comment_author_link() ?></li>
<?php } ?>
<?php endforeach; ?>
</ol>
Grab Category Name
This PHP snippet will get the category of the current post and place it in line where the code is inserted. It would be useful to add a heading or phrase that relates to the category.
<? $cat = get_the_category(); $cat = $cat[0]; echo $cat->cat_name;?>
Dynamic List That Pulls The Most Recent Posts
A Wordpress function often used in sidebars that displays the most recent posts as a list. Replace 3 with how many items you want in your list.
<?php get_archives(‘postbypost’, 3); ?>
Make Your Wordpress Header Image Clickable
Replace the starting div tag for the header with this:
<div id="header" onclick="location.href='http://www.pingable.org/';" style="cursor: pointer;">

I think the “assign an image to a post” code could be very useful with some creativity. Thanks.
Mike
Thanks for the great PHP information. I have been looking for a way to separate trackbacks. I will be implementing this into my blog.

I don’t quite get the “Grab Category Name” thing but I’m sure I’ll figure it out.
Simon
@video Game: If you wanted to add a title or text in your template that had the category name of the category of page it was on, you could use that code.

Thanks the get archives function was exactly what I was after (took about 90 mins of searching!).
Great post.

I found the first one to be the most useful one
Very cool! I’ll try to implement something similar with my new soon-to-code-by-myself WP theme

Man I’ve been searching far and wide for the way to seperate trackbacks from comments. Thanks for finally putting my mind at ease brother.

This is a little jem of a link. I find myself searching for these same code snippets from time to time!

Some good snippets. I like the fact you also told how to modify the wordpress code for your own use. Most people list code or link and never go through how you can change them for your own use.
Keep up the good work always something good on your site.
Nick from no win no fee claims
Very useful information. Making your header logo clickable as a homepage link is certainly worth doing. Thanks
tony from Register domian names
Making image a link with alt tags is one i would always do. I also like the code for trackbacks.
malcolm coles from wordpress duplicate content
Presumably you can combine the image tip and category tip to add a unique image to each category page?

I like the one that pulls the last post. Seems to help alot in seo and makes it easier for people to find more posts they like.
jack from exon mobil
Thanks i like the post title and last post codes. They help make site more seo and easier to navigate.

It’s not working.
DV from Pico RG
Thanks for the code dude, it can be very useful since many have Wordpress installed as the default CMS script
