AMPScript中的IF语句

Question

我对if语句有一个小问题，因为它只填充最后一个elseif

%%[IF @Add3 == "Y" AND @Add4 == "Y" AND @Add5 == "N" THEN
        SET @WhichNom1 = "1"
        SET @WhichNom2 = "2"
ELSEIF @Add3 == "Y" AND @Add4 == "N" AND @Add5 == "Y" THEN
        SET @WhichNom1 = "1"
        SET @WhichNom2 = "3"
ELSEIF @Add3 == "N" AND @Add4 == "Y" AND @Add5 == "Y" THEN
        SET @WhichNom1 = "1"
        SET @WhichNom2 = "3"
]%%
@WhichNom1
@WhichNom2
%%[ENDIF]%%

当最后一个ELSEIF为TRUE时，上面的代码将显示两个变量。我需要做些什么来检查3个语句并为每个场景显示哪一个和哪一个?

Answer 1

只有当最后一个elseif为真时才打印变量

像这样移动它们:

...    
ELSEIF @Add3 == "N" AND @Add4 == "Y" AND @Add5 == "Y" THEN
        SET @WhichNom1 = "1"
        SET @WhichNom2 = "3"
]%%
%%[ENDIF]%%
@WhichNom1
@WhichNom2

所以它们在IF/ELSEIF之外。这样，它们将始终被打印出来，但是变量的设置将根据子句的不同而不同。

编辑:

如果您只希望在其中一条语句为真时打印变量，那么您将(如您所提到的)需要在If语句中打印它们，或者您可以:

SET @WhichNom1 = ""
SET @WhichNom2 = ""

在if语句之前，然后在它们之后:

IF @WhichNom1 != "" THEN @WhichNom1
IF @WhichNom2 != "" THEN @WhichNom2

所以你只有在它们被设置为"以外的东西时才会打印它们

Answer 2

我使用两个IF语句以稍微不同的方式对它进行排序

%%[IF @Add3 == "Y" AND @Add4 == "Y" AND @Add5 == "N" THEN
SET @WhichNom1 = "1"
SET @WhichNom2 = "2"
SET @Status = "T" 
ELSEIF @Add3 == "Y" AND @Add4 == "N" AND @Add5 == "Y" THEN
SET @WhichNom1 = "1"
SET @WhichNom2 = "3"
SET @Status = "T" 
ELSEIF @Add3 == "N" AND @Add4 == "Y" AND @Add5 == "Y" THEN
SET @WhichNom1 = "2"
SET @WhichNom2 = "3"
SET @Status = "T" 
ELSE
SET @Status = "F" 
ENDIF]%%
%%[IF @Status == "T" THEN]%%
@WhichNom1
@WhichNom2
%%[ENDIF]%%

Answer 3

Rob是正确的。此外，如果您想在AMPscript块之外打印@WhichNom1和@WhichNom2，您可能需要编写如下代码:

%%[
IF @Add3 == "Y" AND @Add4 == "Y" AND @Add5 == "N" THEN
SET @WhichNom1 = "1"
SET @WhichNom2 = "2"
SET @Status = "T" 
ELSEIF @Add3 == "Y" AND @Add4 == "N" AND @Add5 == "Y" THEN
SET @WhichNom1 = "1"
SET @WhichNom2 = "3"
SET @Status = "T" 
ELSEIF @Add3 == "N" AND @Add4 == "Y" AND @Add5 == "Y" THEN
SET @WhichNom1 = "2"
SET @WhichNom2 = "3"
SET @Status = "T" 
ELSE
SET @Status = "F" 
ENDIF
]%%
%%[ IF @Status == "T" THEN ]%%
%%= v(@WhichNom1) =%%<br />
%%= v(@WhichNom2) =%%
%%[ ENDIF ]%%
