WordPress: display posts by category ID. Solution with code & example.

Hello Guy!

Often in many blogging sites, you will see two or three columns of the most important categories. Recently I had to do this for a blog. It was a little bit cumbersome and time consuming. So, I would like to share the solution so that you can kill the time waste trying yourself in case you do not know how to do it. In this solution, I show 5 posts at maximum from my chosen three categories.

Let us start and let me show how to do it.

Step One: See the sample what would be the output

In the above image, you will notice that the first category has enough posts, so it can fetch 5 (five) posts for us. But in second column and third column, there are only three posts because those categories do not have more than three posts. And what I want to say at this point is – although we will try to get 5 posts from each category, we will not get enough in case that category has less than 5 (five) posts and this is done automatically.

Step Two: Adding custom function

Now open the functions.php file inside your theme directory and insert these two functions. If there is none, create a functions.php file. And at this point, please remember that all the functions and coding in this file are automatically added during the code execution.

Note that the function names are self descriptive.

Step Three: Embed code in your file(s)

Now open your footer.php file or any other file and add this code. In 99% cases, you may need to customize this small piece of code. The first three lines are category IDs.

Step Four: Link your CSS code

I have put the above CSS code in my style.css file. In 99% cases, you may need to customize according to your requirements.

Step Five: Test everything by opening the link

Now test you code and we are done!

Thank you for reading.

WordPress: get page id and content with example & code

Hey Guys!

Often I see people coming to my site searching with the terms wordpress get page id, wordpress get page content or something similar. I think wordpress developers face situations when they need to get page or post information in customized way. It happened to me too and I would like to share it with others since often people are coming to search this information.

Well. It is very easy and we can solve it quickly.
OK. Now let me show you how to get these information.

Remember one thing that is important for wordpress data fetching of this kind. Your posts and pages information is saved in a single database table and that is wp_posts. The wp_ is the prefix of you database and may differ. But most of the times the database table name is wp_posts and other times it is YourCustomPrefix_posts. We are going to fetch data from this table.

WordPress – print page id:

There is a built-in wordpress function using which you can print the post or page id. When you call this, this directly prints this inforation in your page without the need to use the built-in PHP echo or print function. Remember to keep it in the while loop.

WordPress – get page id:

There is a global variable post which contains the related information of the currest post or page. The name of the variable is: $post and it is actually an object. You can access information just as you access variables from an object. Remember to keep it in the while loop.

You can print all the information in the $post object to see all the variables and their values that is contains.

WordPress – get page content:

Now you know you can get the page or post content from $post->post_content variable. But if you echo or print them, they may look somewhat without formatting. So, you need to use PHP built-in nl2br() function to look the content as it is.

WordPress – get any information of your page or post:

You know you can print all information to check all the available variables and their values through using PHP’s built-in var_dump() function. Suppose you need to get the post title, post type and posting time. We can get them easily in this way.

Please notice that post_title, post_type and post_date are all several database fields from wp_posts table of our wordpress database.

Very easy. Right? And that is all for getting the page or post information.

Thank you for reading.
