The Display Eventbrite plugin allows regular expressions in some shortcode options. This enables powerful filtering and matching rules that some developers may need.
The expression can be a simple text string e.g. Singing which will display all events with Singing anywhere in the title. Note this is case sensitive.
You can also use a regex without the delimiters ( if you want to use delimiters use / )e.g. /singing/i for case insensitive or ^ Singing for all titles staring with Singing or ^(Singing|Shouting) for example using regex or structure etc or any regex features ( you can check your regex at sites like https://regex101.com/ ).
Except as regex can include [ ] a.g ^[Ss]inging the reg ex has to be url-encoded – you can use the input field below to generate the encoded field e.g. ^[Ss]inging becomes %5E%5BSs%5Dinging
To help urlencode there is a simple form below, input the expression and encode it.
