Working with ACF Blocks
In WordPress, Blocks are a page element that can be utilized to display data in a prespecified format. Using the ACF plugin, we are able to display data in Custom Blocks that we can create ourselves. In the example below, we are able to select data in the form of images, text, and URLs to display on our page.
However, these custom blocks can take a wide variety of different forms of data. This can be specified in the Field Groups sections under the ACF tab on the left sidebar, which allows us to create and edit custom blocks
The way this data is displayed on the page is decided by the accompanying code. This code can be found in the Theme Editor section under Appearance. Once here, navigate to the template-parts folder and then the blocks folder. This should contain a list of PHP files, which contain the accompanying format code for each of these custom blocks. This code allows you to modify how inserted data elements are presented.
