Frontier Tutorials / Writing an ObjectNotFoundHandler / Mode 2 Example

Mode 2 Example

A redirect is accomplished by calling mainResponder.redirect or by throwing a redirect scriptError (generally faster).

Your script could either redirect to a fixed, hardcoded URL or calculate the new URL based on the values of lastNomad and remainingPath.

This is the simplest way for the ObjectNotFoundHandler script to work.

The Example

In this example, we will redirect to a page-not-found page with a site search form.

Create the Script and the Reference

In your #tools table, create a script called "PageNotFoundRedirect". It should look like this:

on PageNotFoundRedirect() local pageTbl = html.getPageTableAddress() lastResolvedAdr = pageTbl^.lastNomad remainingPath = pageTbl^.remainingPath newUrl = "http://" + pageTbl^.host + "/onfhTutorial/pageNotFound" scriptError( "!redirect " + newUrl )

At the top level of your site, set the value of "#objectNotFoundHandler" to the address of your new "PageNotFoundRedirect" script. PageNotFoundRedirect is now your objectNotFoundHandler script.

Again at the top level of your site, create a new wptext entry named "pageNotFound", with the following contents:

#title "Page Not Found" <h1>{title}</h1> <p>We're sorry, the page you requested was not found.</p> <p>You may have mis-entered the URL. If not, you may be able to find the page you want via the "Site Outline" or via the search form below.</p> <p> {string( forms^.search )}

Now go back to your browser and reload the page ("http://localhost/onfhTutorial/notThere"). Your page should resemble the following:

Your "page not found" page can be as simple or complex as you like.
