Toby Cox a écrit : Lawrence I tend to use functions where I have a complicated bit of logic (either within or without a search context), more often when I would prefer no white space in between lines you can do it like this [hideif [myVar]=1][!]<!-- comment here to avoid generating line break --> [/!][text]myNewVar=100[/text][!] [/!][/hideif] is the same as this [function name=generateNewVar] [hideif [myVar]=1] [text scope=global]myNewVar=100[/text] [/hideif] [return][/return] [/function][generateNewVar] I find the 2nd one easier to read. It is especially handy when generating XML, I find. Alternatively I would use it for text translation - [translateMyText textToTranslate=[myDateVar]&language=french] - and MySQL functions - somehow it's easier to print out [findMyRecords myVar=1] than do all the steps necessary for Normally a repeated bit of logic where the output is always in the same format, but small input elements change is where I would use it most. In the example you have given, I would almost always write this as inline code. If, however, you wanted to have a find function that always printed the results out in the same manner, you could do the following: [function name=getResults] [search db=[whichDb].db&&neSKUdata=[blank]] [founditems] [return]<div class"myclass">[SKU]-[name]</div>[/return] [/founditems] [showif [numfound]=0] [return]Nothing to see here[/return] [/showif] [/search] [/function] and on your page <div class="resultsContainer"> [getResults whichDb=myDb] </div> and again somewhere else <div class="resultsContainer"> [getResults whichDb=anotherDb] </div> Hope this helps....

Toby, I'm trying to understand in which case I should use the [function] or not. Your example is clear, It looks like it would be nice to have all the webdna code in separate files, and have only the result called in the page, that would make page codes clear. for the break/stop the documentation says : "'The [return] context does NOT 'break out' of a function call, so it is possible to use one or more [return] contexts to 'tailor' the functions output. " Kenneth, how would you use an array with this kind of search function? Thanks Lawrence

Toby, I'm trying to understand in which case I should use the [function] or not. Your example is clear, It looks like it would be nice to have all the webdna code in separate files, and have only the result called in the page, that would make page codes clear. for the break/stop the documentation says : "'The [return] context does NOT 'break out' of a function call, so it is possible to use one or more [return] contexts to 'tailor' the functions output. " Kenneth, how would you use an array with this kind of search function? Thanks Lawrence
