Everyone, please don't forget (if you ever need this tip) that you can have as many [foundItem] loops in a results template as you want. Let's say you have a single [foundItems] loop on your results template but you want to use today's date somewhere INSIDE that loop.Well, instead of thinking that this will be a hassle, just 'end the loop', then display today's date with a [date] tag, then 'start another loop'. You can do all three steps simply by using:[/founditems] [date] [founditems]See what we're doing here? Instead of actually displaying today's date 'inside' your original [foundItems] loop, we display today's date 'outside the loop' by splitting the original [foundItems] loop into two separate [foundItems] loops ... so the entire page would actually have all the following tags:[foundItems] <--- some database field values inside this first loop [/foundItems] [date] <--- this gives you today's date [foundItems] <--- (more database field values inside this second loop [/foundItems]By the way, there's another way to get the very same results *within* the original [foundItems] loop (if you have some aesthetic reason for *not* splitting the original loop into two separate loops) ... but it requires setting variable values outside the loop and then using those values inside the loop. This 'variable' technique is more complicated and not necessary in most cases, but it can be done! :) ------------------------------------ To leave this talk list send an email to macjordomo@smithmicro.com with BODY unsubscribe WebDNA-Talk ------------------------------------ Associated Messages, from the most recent to the oldest:
