OK, same project to re-purpose the Classifieds application in BEGINNING ASP 3.0 to a comicbook database ...
This is another brainteaser that should have been easy to resolve but just doesn't seem to work for me ... The original application includes a form page for editing the details of an "item". In my case the item is a comicbook. The page functions just fine as long as I stick with text fields, but I run into problems when I try to change a couple of the text fields into checkboxes.
So, here's the code of the Item.asp page with text fields:
Code:
<%
Dim blnNew
' detect whether the user is adding a new item or editing an existing one
Select Case Request.QueryString("Action")
Case "AddNew"
blnNew = True
Case "Edit"
blnNew = False
End Select
%>
<div id="fullwidth">
<%
If blnNew Then
Response.Write _
"<center><h1>Add an issue to the database</h1></center>" & _
"<center><p>Please add the following information for the issue you've just acquired</p> "
Else
Response.Write _
"<center><h1>Edit data for issue you already have</h1></center>" & _
"<center><p>Please edit the information for this item</p> "
Dim rsItem
Set rsItem = Server.CreateObject("ADODB.Recordset")
strSQL = "SELECT Title.titleName, Item.idItem, Item.issue, Item.[month], Item.[year], " & _
" Item.cond, Item.gcdb, Item.image, Item.cents, Item.have, Item.want, Item.note " & _
" FROM Title INNER JOIN Item ON Title.idTitle = Item.idTitle " & _
" ORDER BY titleName,month;"
rsItem.Open strSQL, objConn, adOpenForwardOnly, adLockOptimistic, adCmdText
End If
%>
<form action="addItem.asp" method="post">
<%
If blnNew Then %>
<input type="Hidden" name="idItem" value=""> <%
Else %>
<input type="Hidden" name="idItem" value="<%= Request("Item") %>"> <%
End If
%>
<table border='0'>

<td width=20% rowspan=8> </td>
<td align="right">Title:</td>

<input type="Submit"

<input type="Reset"></TD>
</TR>
</table>
</form>
The object here is to create a dual-purpose page that can be used to add new items to the database and to edit existing items.
My problem arises when I try to change the "cents", "have" and "want" fields to checkboxes. This bit of code almost works:
Code:
<td align="right">Cents:</td>
<td><% If rsItem("cents") then strChecked = " checked" End If %>
<input type="checkbox" name="cents" value="<%=rsItem("cents")%>"<%=strChecked%>>
</td>
<td> </td>
<td> </td>
</tr>
<tr>
<td align="right">Have:</td>
<td><% If rsItem("have") then strChecked = " checked" End If %>
<input type="checkbox" name="have" value="<%=rsItem("have")%>"<%=strChecked%>>
</td>
<td align="right">Want:</td>
<td><% If rsItem("want") then strChecked = " checked" End If %>
<input type="checkbox" name="want" value="<%=rsItem("want")%>"<%=strChecked%>>
</td>
(The variable "strChecked" is DIMmed further up the page!)
I say "almost" because it works fine (returns a checked checkbox when the related field in the database is checked) when I'm looking at an existing database entry, but it fails when I try to use it to add an entirely new item, with this error message:
Code:
Microsoft VBScript runtime error '800a000d'
Type mismatch
/publishing/comics/collecting/admin/item2.asp, line 107
If anyone knows how to solve this problem, I'd be ever so grateful ...
