Convert checkbox values from an array to a string

Question

I have a front end form with multiple checkboxes. Is it possible to convert the checkbox values from an array to a string before it's submitted to the database?

I want to save the checkbox values into a PlainText Craft field in the database.

If I try to submit the front end form checkbox values into a PlainText field currently, I get the error: trim() expects parameter 1 to be string, array given

It looks like perhaps using the join or merge filter may accomplish this but I'm not sure.

Answer 1

If you have access to jQuery in your project, you can do this.

Change the name of your checkboxes so craft doesn't look at them when the form gets posted and have a hidden input (named inline with your form) that you populate using using js.

This uses jQuery but you can convert to Javascript if needed. It's not perfect but it might get you on the way :)

Answer 2

If you need to do this in a twig template, the join filter will do the job.

Use {{ yourCheckboxesValues|join(', ') }} to print something like that : value1, value2, value3.
