    We have a custom field search working very well through the use of your plugin. However, we want to try and limit the user’s input to 5 characters maximum so that they are funnelled directly towards the correct results – in this case, a postcode search of no more than four characters and a space.

    Is this doable?

    Thanks in advance

    I believe yes, with an additional code. First try putting this into the functions.php file in your active theme directory:

    This code will append a script to the page footer, which then sets the maximum input value of the input field to 5 characters only. While it doesn’t do an input validation, but at least it limits the number of characters.

    If you also want redirection when there is a valid results, then try the following code as well:

    This should redirect the page without showing the results, when there is at least one available.

    Let’s hope these will work.
