asp dropdown list with a condition

229 New Member
Hi, Would anyone know how to populate an asp dropdown with a dependant condition.

I need this dropdown to select only artists, ie from the authortwo field where in another field, ie extrathree, the word yes is written.



Expand|Select|Wrap|Line Numbers
  1.   <form method="Post">
  2.       <div>
  3. <select onChange="window.location='' + this.options[this.selectedIndex].value">
  4. <OPTION VALUE = 'artists'>&nbsp;artists</Option>
  5. <OPTION>-----------------------------------------------------</Option>
  6. <%        
  7.     Set oRs=Server.CreateObject("adodb.recordset")
  8.     strSQL = "SELECT DISTINCT AuthorTwo FROM tblGreetingPostCards ORDER BY AuthorTwo"
  9.     oRs.Open strSQL, conn        
  10.  
  11.     Do while not oRs.EOF
  12.         if Request.Form("GreetingPostCards") = oRs("AuthorTwo") then 'if this is the selected one then display as selected
  13.             Response.Write "<OPTION VALUE = '" & oRS ("AuthorTwo") & "' SELECTED>"
  14.             Response.Write oRs("AuthorTwo") & "</Option>"
  15.             oRs.MoveNext 
  16.     else
  17.             Response.Write "<OPTION VALUE = 'http://www.mysite.com/artgallery.asp?AuthorTwo=" & oRs ("AuthorTwo") & "'>&nbsp;"
  18.             Response.Write oRs("AuthorTwo") & "</Option>"
  19.             oRs.MoveNext 
  20.         end if
  21.     loop        
  22.     %>
  23. </SELECT>
  24. </div>
  25.   </form>
somehow to combine another condition like


Expand|Select|Wrap|Line Numbers
  1.                                     <%
  2. If InStr(rsCard("extrathree"),"yes") > 0 Then
  3. %>
  4.  
  5.  
  6.  
  7. <I><a href="portfol.asp?authortwo=<%=rsCard("authortwo")%>" title="">info&nbsp;</I><a>
  8. <%
  9. Else
  10. %>
  11.  
  12. <%
  13. End If
  14. %>  
Any help would be great.
Thanks in advance

Hello fran7,

I am having a hard time understanding what you are trying to do. I really would like to help you out. Can you give a better example on what you are trying to accomplish? The more detail you can provide in this case is better. No need for posting anymore code just what you wish to accomplish in detail.

Here is a stab at trying to answer your questing with what I have read above.

Why don’t you just extend your SQL syntax to add in the condition of the field “extrathree” equaling the word “yes” like this:

Expand|Select|Wrap|Line Numbers
  1. SELECT DISTINCT AuthorTwo FROM tblGreetingPostCards WHERE extrathree = ‘yes’ ORDER BY AuthorTwo

Also Richard, this really has nothing to do with your question, just a helpful observation. I see that you are trying to categorize things within your drop down like so...

Expand|Select|Wrap|Line Numbers
  1. <OPTION VALUE = 'artists'>&nbsp;artists</Option>
  2. <OPTION>-----------------------------------------------------</Option>
  3.  
Google <OPTGROUP>

EG:
Expand|Select|Wrap|Line Numbers
  1. <select>
  2.    <optgroup label="Artists">
  3.       <option value="Artist1">Artist 1</option>
  4.       <option value="Artist2">Artist 2</option>
  5.       <option value="Artist3">Artist 3</option>
  6.    </optgroup>
  7.

Dear Mark, Thanks for the reply.

I hope I can explain better. Basically the dropdown list I have above works fine. But I need it to be populated only by the artists who have " yes" written in another field called "extrathree ".

Summary
I have a field called authortwo with all my artists names.
I have another field extrathree where selective artists have a "yes" written. Those without the "yes" at the moment are left blank but I could fill them with "no" for example.

So the problem is to populate the dropdown with only those artists names with "yes" written in the field "extrathree "

Any help would be great.
Thanks
Richard

Hi Richard,

I think CroCrew already answered your question didn't he? If you change your SQL string to:

Expand|Select|Wrap|Line Numbers
  1. strSQL = "SELECT DISTINCT AuthorTwo FROM tblGreetingPostCards WHERE extrathree = 'yes' ORDER BY AuthorTwo"
Then only the authors with yes next to their name in the column extrathree will be selected and included in your drop down.

Or is it something else you are after?

Let us know,

Dr B

Yes, CroCrew answered your question accurately fran7 - I was merely making a non-related observation ;)
