What is the ACF add-on
The ACF add-on is an extension that makes it possible for the ACF plugin and WPSOLR to work in tandem. You can now use ACF fields with WPSOLR. This will allow you to create custom facets.
Install the ACF plugin
Install the Advanced Custom Fields plugin and activate it.
Create an ACF facet for WPSOLR
Click on “Custom Fields”, then on “Add new”
Choose a title for the new field group.
Add a new field. Choose a label and a name then choose the field type. Save when you’re done.
Then scroll down and choose where the field group will be applied. I chose to use it on WooCommerce Products. You can choose to use many other field types as well. Here i am going to choose the “Select” field.
Then modify the products.
Then head over to the WPSOLR plugin and make the necessary changes. Scroll down and read the rest of this guide to get a better understanding of the WPSOLR configuration that you need to do.
We can see there is exactly the number of products assigned in each choice and the products are displayed correctly when clicking on the “tshirt” checkbox.
Create additional ACF facets
We can create a lot more ACF facets that can fit your individual needs.
Add a repeater with two text fields
Add a new ACF field then choose a name. Then choose the field type, in this case i’m choosing the “Repeater” field type.
Add a repeater field. This will be a text field for the product type.
Then add another field for the product color. When you’re done save, then edit a product.
You should see something like this. Fill in the information then save. Then head for the WPSOLR admin.
Click on the “Data” section you will see later in this article.
Then select our new fields.
Choose “Filter”.
And select the new fields to use as filters.
Choose a label for the product color and a layout.
Then choose a label for the product type and a layout. Then test your website search.
As you can see we now have a new filter that can sort products by color and product type.
Add a repeater with fields for uploading files.
Create a field for the product manufacturer and select the repeater field type.
Then create two repeater field, one for the manufacturer history, the other one for the list of the total number of manufacturer products, then save.
Edit a product then upload the two files. Since we are dealing with files, we will not be able to generate a facet but if you search for a word that is contained in one of the files, you should find the right product.
As you can see, We ended up on the right product.
Add a repeater that contains another repeater and fields for uploading files .
Create a new field and choose the “Repeater” field type.
Create a sub repeater field and choose the “Repeater” field type again.
Add another sub field and choose the text field type.
Here I chose to add another text field.
Then add two other fields.
The two fields will both have the “File” field type. Save and edit a product.
Add the product title, the category and the two wikipedia files. Save and configure WPSOLR. Then test your website search.
The WPSOLR facets work correctly.
And website search works as well. Fabric was a word used in the Tshirt wikipedia page. We can see that WPSOLR returned the correct result.
Add a file field type
Add a new field. Choose a label and select the “File” field type. You can also choose the return value. You can return it as an array which return the data as an array, as a file url which returns the data as a string and as a file id which returns the data as an integer. This is useful if you want to use this field in your PHP code.
Edit a product and upload a file in the new field.
Now when you search for words used in the file, in my case “march 20”, WPSOLR should return the products that we uploaded the file too.
We can see that WPSOLR search is working well.
Add a clone field
Create a new field. Choose a label and pick the “Clone” field type. Then pick the field that you are going to clone. Choose the way you want to display the new field. When you’re done save and edit a product.

Add a new field then choose a label and select the “Flexible Content” field type.
Then choose a label for the new flexible content layout and select a layout. Then add a subfield. In my case it is a repeater.
Add a field inside the new repeater. Here I chose a text field.
And add a second field.
Add a second field in the flexible content layout.
Here i added a text field. Then i am going to add two new fields for the layout.
Next I am going to create a second flexible content layout.
Here I created a second layout with a new file field by clicking the “Add New” button.
Then i’m going to add two new fields.
I chose to use the file field type both times.
I added a new layout with a text field.
Then I added two other text fields. When you’re done save and edit a product.
