<input type="button">

One issue I found is that the closing tags for the ‘input’ ASP value tags have a stray closing slash between the ‘%’ and ‘>’, as in:
value=”"

This prevented the page from loading until corrected.

The major differences are TOP vs LIMIT (ie, select top 2 from table in MSSQL vs select * from table Limit 2 in MySql), multi-phrase column name ticking (ie, backticks vs [] brackets, and group by’s are not as strickt in mysql. Other than a few other advanced techniques (triggers, etc) the syntax is very similar.

In this particular example, the only thing that would need to be changed would be to change [zipcode] to `zipcode` (note, those are back ticks, not quote marks). You can also leave the ticks off completely as it is a single string (ie, the field name is not `zip code` with a space).

In this case for US-based 5-digit zipcodes, we should do something like this:

<%
Function digitsonly(teststr)
  dim isValid
  dim regEx
  
  isValid = True
  set regEx = New RegExp
  
  regEx.IgnoreCase = false
  
  regEx.Pattern = "^[0-9]{5}$"
  isValid = regEx.Test(teststr)
  
  digitsonly = isValid
  
End Function

zipcode = request("zipcode")

if len(zipcode) = 5 then
  if digitsonly(zipcode) = false then
    response.write "bad data"
    response.end
  else
    'do the query and the rest of the above ASP back end functions.
end if
%>

Unfortunately this was part of an intranet project at my last company where I am no longer employed. Thus, I don’t have access to the source code.

However, I did some copy paste action and made a full page of the posted code. This is untested as I don’t have ASP or MSSQL on my blog webserver.

I have added a link to the source in the orig post. Again, un-tested.

The best thing to do would be to store a session variable for the zipcode on the following page.

formactionpage.asp:

session("zipcode") = request.form("zipcode")

and in your form, pre-populate the value for the zip code:

<input type="text" name="zipcode" id="zipcode" value="<%= session("zipcode") %>" />

And finally, in the footer somewhere, call the javascript to iniitate the query. Note, it’s important that this JS happens AFTER the form field is populated from the session variable (thus, a window.onload call in the head section will most likely be problematic)

<script type="text/javascript">
function postload() {
  getZipcode(document.getElementById("zipcode"))
}

window.onload = postload;

This is un-tested and off the seat of my pants, so there may be some errors and/or typos

Hope this gives you some guidance. Good luck
