The server waits until the file appears on disk
numero = 190WaitForFile will wait a specified number of seconds (default 30) until the file appears. The template will not finish executing and the HTML will not be returned to the visiting browser until the WaitForFile finishes.
Example[waitforfile file=ICVer001.ans]Some WebDNA to parse the ICVerify answer file format and do something important with it[/WaitForFile]You can write WebDNA that learns if the WaitForFile timed out:
[text]succeeded=F[/text][waitforfile file=FileToWaitFor.txt]Some WebDNA to execute if the file is found[text]succeeded=T[/text][/waitforfile][showif [succeeded]=T] File was found! [/showif][showif [succeeded]=F] File was not found! [/showif]The value of [succeeded] becomes either T or F, depending on whether or not the [waitforfile] succeeded in finding the file on disk before the timeout expired.
