What you can do with WordPress<\/a> is limited only by your imagination and your ability to write or find the right piece of code. Today I’d like to share with you a couple of very useful snippets and tricks that can help you create custom functionality for your WordPress based website.<\/p>\n

Insert ads between posts<\/h2>\n

You’ve probably seen some websites place ads after, say, the 3rd post. Here’s how you can do it with just two lines of code.<\/p>\n

Find the following line of code in your loop (blog posts, category, tag…)<\/p>\n

<?php endwhile; ?><\/pre>\n
Just before<\/strong> this line, place the following code:<\/p>\n
<?php if(!$show_ads){ ?>\nInsert Code Here\n<?php $show_ads = 3; } ?><\/pre>\n
Replace Insert Code Here<\/strong> with your ad code or whatever you wish to appear after the 3rd post.<\/p>\n
Of course, if you prefer to put it after a 5th post or other, just change the number after $show_ads<\/strong>.<\/p>\n

Limit WP post revisions easily<\/h2>\n
Whenever you save a change in a WordPress post or page, the system saves a version of that post. This can easily bring a lot of junk in the database, especially if you tend to make many corrections or save frequently as you prepare a post.<\/p>\n
There are several plugins for removing revisions from the database, but there’s also a very easy way to limit the number of saved revisions for each post\/page.<\/p>\n
1 line of wp_config code is all you need:<\/p>\n
define( 'WP_POST_REVISIONS', 3 );<\/pre>\n
WP_POST_REVISIONS:<\/p>\n
