“Are there any articles published after February 10th that were written by Pippo? ”

Here, simply using the knowledge we already have, it is possible to create an indefinite number of custom cycles within the same page, this example would be very useful for a magazine-style theme!

Obviously my main intent is to show you how to create custom Loops in the simplest way possible and in fact in this article I have only talked to you about the configuration that allows australia phone number data us to separate the articles based on the saving category, but a WP_Query instance can be customized in many ways, all indicated within the Codex .

I am not interested in going into detail and explaining to you one by one the parameters that you can use, also because perhaps a whole day would not be enough! Instead, I would like to make you reflect for a moment on the operations that are performed and why I recommend you use this class.

You should always keep in mind that every time you use WP_Query you are doing some operations with the database, in a few words you are telling WordPress something like:

“ Do you check if there are any items in the Shoes category in the database? If you find something, return the first X items to me .”

or



Each of these operations uses a lot of your server's resources , resources that slow down the loading of your website, so think carefully about how many queries your project will need and what solutions you could use to improve the performance of your server.

The nice thing is that by using this class, unlike the functions presented at the beginning of the article, you use the correct syntax that WordPress itself uses to create its own cycles and this means that if you install a plugin that optimizes the performance of your server, such as any plugin to manage the cache, it will be able to optimize your code too.

This will not be possible if you use MySQL queries or other older solutions because they will not respect the standards of this platform and to be able to optimize the added features you will have to write more custom code.

Conclusions
Knowing how to use WP_Query correctly requires a lot of practice and you can't rely on reading a single article. Don't be discouraged if you have difficulty with your first experiments or get unexpected results, this class is really very powerful and I can assure you that since I discovered it I have never stopped using it .
