Re: Formula to replace special characters - slug creation

We’re a film festival looking to pull the titles of our submissions in order to create slugs that can be used to create virtual posts on our WordPress site.

I need a way to parse just the text from the submission, with the ability to remove special characters (i.e. " ’ ! ? ; : @ # $ % ^ etc.).

I’ve gotten to this point so far:

LOWER(SUBSTITUTE({English Title}, " ", "-"))

This allows me to hyphenate the titles, but still includes special characters. Is anyone aware of a workaround for this, or do I need to manually create my slugs in this case?

Cheers!

For a long text field, you need to add another SUBSTITUTE layer that replaces \n with %0A

That worked - thanks so much Justin! :slightly_smiling_face:

There should be an easy-to-use function for this, really. It’s so common to generate slugs for url-related things.

@W_Vann_Hall FYI you should use ENCODE_URL_COMPONENT for url encoding, it’s different than slugs.

I’ve taken quite a good care to handle all ascii chars.

The formula posted by @W_Vann_Hall was made in September of 2018, before the ENCODE_URL_COMPONENT() function was added to Airtable.

That works well, thank you!

Hi, Above solution looks good, but how would you handle the duplicate text?

Curious about the solution.

Thanks in advance
