Re: [WebDNA] [lookup] fails when using [url] to wrap a value for potential "&" char?
This WebDNA talk-list message is from 2009
It keeps the original formatting.

interpreted = N
texte = John,I url the values in lookups all the time.The behavior you see could be explained if [ccc] already contains a url'ed value. For example:[text]ccc=[url]&[/url][/text][lookup db=^db/aaa.db&lookInField=bbb&value=[URL][ccc][/ URL]&returnField=ddd¬Found=eee]This will not find the value "&" because the value got url'ed twice, and the second time encoded the % sign as %25, so the lookup would unurl once and therefore look for the literal string "%26" instead of the desired "&".Brian FriesBrainScan SoftwareOn Aug 14, 2009, at 3:41 PM, John Butler wrote:> I am really surprised to see this behavior:>> This:> [lookup db=^db/aaa.db&lookInField=bbb&value=[URL][ccc][/ > URL]&returnField=ddd¬Found=eee]> returns:> eee>> But this:> [lookup db=^db/ > aaa.db&lookInField=bbb&value=[ccc]&returnField=ddd¬Found=eee]> returns:> the value I expect (the value for [ddd] in the found record).>> So then won't the latter (working) lookup break when the 'bbb' field > may contain an "&" char (when we don't use [url])?!>> I can work around with [search].. but what if I need the speed of > the [lookup]?>> --> Can anyone confirm this?
