How to Add Ads after Read More Tag in WordPress

ads-after-more-tag

Today, this site finally reaches a new milestone, 500+ page views/day. Even though it’s very low, I decided to add ads in this blog.

This blog uses full content in archive, and I’m breaking long content using manual “read more tag” (not using excerpt).

Note: You can add more tag using the editor toolbar or using <!--more--> in text editor.

I want to add the Ads in all blog post after read more tag, so technically when visitor click the read more, they will see ads on the top of the page.

It’s tricky because when we use the_content filter, WordPress already transform <!--more--> tag into HTML tag, something like <span id="more-1325"></span>. Here’s the code:

f(x) Photo Tag Admin Page

When I write f(x) Photo Tag plugin, I think it’s best to put the menu under “Media” because it’s simpler, and also make sense.

Sometimes we want to add custom post type admin menu as sub-menu item on other post type or under settings page, because it make sense (not all post type need to be parent menu), and I like this approach because it make WordPress Admin cleaner.

And Here’s how I do that:

How to update get_currentuserinfo() for WordPress 4.5+

0

In one of my plugin, f(x) Profile Dashboard Widget, I use get_currentuserinfo() to get current user data, apparently it’s deprecated in WP 4.5.

Here’s the code I use to replace it with wp_get_current_user(): while maintaining backward compatibility.

Previous Code:

global $current_user;
get_currentuserinfo();

New Code (WP 4.5):

if( function_exists( 'wp_get_current_user' ) ){
    $current_user = wp_get_current_user();
}
else{
    global $current_user;
    get_currentuserinfo();
}

Responsive Fixed Width Sidebar: Why and How?

layout-percentage-width

In responsive design, usually we use percentage width for sidebar and content width. It’s easy to do. For example 60% content with 40% sidebar. So both Content and Sidebar width will scale using this ratio.

This approach is widely use, but I don’t personally like it. I prefer to have a fixed width sidebar, like this:

layout-fixed-width-sidebar

Implementing fixed width sidebar in responsive design is actually possible (even though it’s  a little tricky).

In this post I will cover both 2 column and 3 column layout with full example.

Note: I’m not using JS to create the layout, And I also did not use calc() CSS because a lot of browser don’t support this yet.

But why use fixed width sidebar?

Here are several reasons why we might want fixed width sidebar: Read More Responsive Fixed Width Sidebar: Why and How?

Short Korean Drama Series For Your Precious Time

0

I watch a lot of Korean Drama. Probably around 50+ titles so far. It’s my guilty pleasure.

I watched several US series like “Friends”, “How I Met Your Mother”, “Big Bang Theory” and all was fun only in first couples season. If the series is popular they will keep it going until it turn bad and no one enjoy it. They will end the series with a bad after taste (most of the time).

I prefer Korean Drama because usually only contain one season and that’s only 12-20 episode. But series in this list is even shorter. Only max 3 episodes.
