Heres our 'slick' error code, this is more used to generate static URL's from WebDNA databases, or redirect to a standard error page for a site. Might help some people though with the custom error stuff .. We run a modified errormessages.db which has an entry for TemplateNotFound as follows: TemplateNotFound [showif [fileinfo file=/interpret.inc][exists][/fileinfo]=T][text]show_error=F[/ text][text]hide_error_redirect=F[/text][include file=/interpret.inc][/showif][hideif [hide_error_redirect]=T][showif [fileinfo file=/error.html][exists][/fileinfo]=T][redirect /error.html][/showif][/hideif][hideif [show_error]=F]Error: template '[param1]' not found[/hideif] What this does in a nutshell: Looks for our interpret.inc file which is the connector to the database, if this exists, include it. If it doesn't exist check for an error.html in the root of the website directory, if that exists redirect to it. If it doesn't exist just show the standard template 'blah blah' not found error ... Then the interpret.inc file looks something like this .. example below shows usage for a product database and a request for a url such as http://www.domain.com/products/12345.html where 12345 is the ID of the product in the database. [search db=/db/products.db&eqPRODUCT_IDdata=[middle startafter=/products/&endbefore=.][thisurl][/middle]] [founditems] [text]write_error=F[/text] [!] ## Do not write to errormessages.txt --[/!] [include file=/templates/[product_template]] [/founditems] [showif [numfound]=0] [text]show_error=T[/text] [/showif] [/search] NOTE: you will need to create the /products/ folder on the server and leave it empty for the above to work - otherwise you will hit a webserver error page .. The above has proven itself to be very robust for us - we once took 127,000 page views in 2 hours on a site that uses the above method, the server ticked along nicely - a little slower than normal but it didn't have any problems. Adding code like this will also typically add 2-3 ticks to the generation of the page. I'm working on a caching system at the moment for this to allow our CMS to cache compiled pages so each one is not regenerated .. will let you know how that goes ;) If anyone has any questions - please yell out.
