Eureka !!!

I searched for a long time and now I found a solution to one of the main problems, facing WordPress developers. Everyone usually thinks, what CMS WordPress initially, the standard assembly really can’t do anything and you need to write separate plugins, but today I want to argue with this.

To make it clearer, I will tell on the task, who is standing in front of me now.

Create a real estate website. I took from the Internet a theme that was intended for a real estate website, but she was able to filter data by only one criterion (prices, number of bedrooms, meterage … ). All of these criteria are separate categories in WordPress.. It turns out that I have a task to make a non-standard request, which will output data, which are in several categories.

By default, to display from one category in WordPress, it is enough to make a request through the URL

https://e-romanova.com/?cat=16

In my case, it is necessary to write a small code in a file, containing a data output loop. I have this file index.php. Replace the code:

New code including filtering:

‘category__and‘ => array(8,25) – 8 and 25 these are the categories by which we will filter. The result will be records that are in both categories. posts_per_page – amount of time spent on the page.

order by – sort by field ‘title‘.

order – shows, that sorting should be in reverse order (DESC).

And then the matter of technology, create a form and make a POST request. Getting data from a request, just put it in the right place.
