DateAdd () in a special format

Question

I tried all the ways to add a month to a specific date, and then return it in a specific format, but I'm at a loss. Here is my code, but I need to format it:

replace( formatdatetime( dateadd( "m" , 1 , request("date") ), 0 ) , "/" , "-" ) & "' )

request("date")is in format yyyyy-dd-mm hh:mm:ssand that i need a new date.

Answer 1

The following should work perfectly:

replace( formatdatetime( dateadd( "m" , 1 , cDate(request("date")) ), 0 ) , "/" , "-" )

Note the use of the function cDateto explicitly convert a value to a date.

Edit:

I deleted the last part of your code & "' ), otherwise it gave me an error.
