passing paramaters to asp pages 1

harpconn · Mar 31, 2003

I need to pass a textstring and an array from one asp page to another. They are created by program code, not by form input.

I am getting various errors, including "type mismatch" even though I have identical Dim statements in each page.

Here's my test code. Please tell me what I'm doing wrong.

PAGE1
-------
<%@Language=VBscript%>
<%Option Explicit%>

<html>

<head>
<title>TempTest</title>
</head>

<body>
<%
Dim MyList, MyArray(5), I

MyList = "abcde"
For I = 1 to 5
MyArray(i)= I
next
%>
[<a href="

http://www.wildmind.net/~wildmindbooks/temptest2.asp?MyList2=MyList&MyArray2=MyArray">Pass

Paramaters</a>]

</body>

</html>
--------------------------------------------------------

PAGE 2
<%@Language=VBscript%>
<%Option Explicit%>

<html>

<head>
<title>TempTest2</title>
</head>

<body>
<%
Dim MyList2, MyArray2(5), I2

MyList2 = request.querystring("MyList&quot

response.write "*** DEBUG: MyList2 = " & MyList2 & " "

MyArray2 = request.querystring("MyArray&quot

For I2 = 1 to 5
response.write MyArray2(I2) & " "
next

%>
</body>

</html>

I am betting your getting the value "MyList" for your querystring variable MyList2 and the value "MyArray" for the QueryString variable MyArray2

The problem here is that your never actually outputting those ASP variables into the HTML. What you need to do is write the values of those variables into the link. The MyList variable will be easy because you can simply write it out like so:

Code:

mypage.asp?MyList2=<%=MyList%>

The array is a little more difficult because you cannot pass arrays inside the querystring, only strings. The easiest solution would be to use the Join function to Join the array into a delimited astring. Then on the second page you could use the Split function to split the string back into an array:

Code:

Dim arrStr
arrStr = Join(myArray,&quot;,&quot;)    'join together with comma delimiter
%><a href=&quot;myPage.asp?myArray=<%=arrStr%>&quot;>My Link</a><%

Then on the next page:
Dim myArray, arrStr
arrStr = Request.QueryString(&quot;myArray&quot;)
myArray = Split(arrStr,&quot;,&quot;)   'split on comma delimiter

Hope this helps,

That took me a long way. Thanks. Both the strings are getting across OK. But I'm still getting a "type mismatch" error on the second pages split line 19. So I don't end up with an array on page 2.

I don't understand why. Here's the revised code:

PAGE1
---------------
<%@Language=VBscript%>
<%Option Explicit%>

<html>

<head>
<title>TempTest</title>
</head>

<body>
<%
Dim MyList, MyArray(5), arrString, I

MyList = "abcde"

For I = 0 to 4
MyArray(I)= I
next

arrString=Join(MyArray,",&quot

%>

[<a href="

http://www.wildmind.net/~wildmindbo...%=MyList%>&MyArray2=<%=arrString%>">Pass

Parameters</a>]

</body>

</html>
----------------------
PAGE 2
<%@Language=VBscript%>
<%Option Explicit%>

<html>

<head>
<title>TempTest2</title>
</head>

<body>
<%
Dim MyList2, MyArray2(5), arrString2, I2

MyList2 = request.querystring("MyList2&quot

response.write "*** DEBUG14: MyList2 = " & MyList2 & " "

arrString2 = request.querystring("MyArray2&quot

response.write "*** DEBUG17: arrString2= " & arrString2 & " "
MyArray2=Split(arrString2,",&quot

For I2 = 0 to 4
response.write MyArray2(I2) & " "
next

%>
</body>

</html>

Thanks. You're the greatest!
