Tips & Tricks
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 rel="nofollow" href="http://gravatar.com" title="Get a Gravatar today!"><?php gravatar(); ?></a> <?php } ?>
Tips & Tricks
Echo custom fields in any category
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.
Tips & Tricks
Disable caching of your site or post
I talked about Disabling search engine on search pages in a previous post using the meta tag
. Today lets go over the web bots Cached copy of your site. If you are working on builder your blog, or have a temporary site up, use the following code:
<meta name="robots" content="noarchive">
This will tell any bot to follow your site, index it, but prevents a cached copy of this page from being available in the search results.
Tips & Tricks
Disable search engine on search pages
A good idea when trying to get the most out of your blog is usging the meta tag to tell the web bots to search & index your site. But for good SEO you should apply this code in your header.php
file of your WordPress blog.
<?php if(is_search()) { ?> <meta name="robots" content="noindex, nofollow" /> <?php }?>
This will keep your site from getting a hit from bots over duplicate entries. 🙂
