5 WordPress PHP Code Snippets

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;">

www.pingable.org

  7. @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.

  13. Very useful stuff. I don’t know how many times I have had to go searching for the same little code snippets!

  14. 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.
