I am working on a project and have a HTML page that asks users for userID and password before going to an ASP page. I am trying to figure out how to validate that the ID is numeric and the same password is entered twice.
I was also wondering if the code goes on the ASP page or the HTML page.
If anyone has any ideas, it would be greatly appriciated.
Thanks

  maker = &quot;login.asp?rp=&quot; & Request.Form(&quot;goto&quot;) & &quot;&type=1&quot;
  sql = &quot;select * from usermaster where userID = '&quot;& Request.Form(&quot;userid&quot;) &&quot;' and password = '&quot;& Request.Form(&quot;pwd&quot;) &&quot;';&quot;
  set rs = server.CreateObject(&quot;ADODB.RecordSet&quot;)
  rs.Open sql, con, 1, 3
  if rs.EOF = true then 
 'here is where if no username is found then   
 Response.Redirect maker
  else
 'if username is found then
   session(&quot;username&quot;) = Request.Form(&quot;userID&quot;) 
   Response.Redirect &quot;play_match.htm&quot;
  end if 
 rs.Close 
 set rs = nothing

Hi Davy770,
Here is simple code:

<html>
<head>
<title>Login</title>
</head>
<BODY>
<SCRIPT LANGUAGE=&quot;JavaScript&quot;>
<!--
function validate()
{
var errormessage='';
for ( var i=1; i <= document.forms[0].ID.value.length;i++)
{
if (isNaN(parseInt(document.forms[0].ID.value.substring(i-1,20))))
errormessage='ID is corrupt!\n'
}
if ((document.forms[0].password1.value) != (document.forms[0].password2.value))
errormessage='Must be same password!\n'
if (errormessage!=&quot;&quot;) alert (errormessage);
else
{
return true;
}
return false;
}
// -->
</SCRIPT>

<form ACTION=&quot;default.asp &quot; METHOD=&quot;post&quot; onSubmit=&quot;return validate();&quot;>
<table border=&quot;0&quot;>
<tr>
<td ALIGN=&quot;right&quot;>ID:</td>
<td><input TYPE=&quot;text&quot; NAME=&quot;ID&quot; size=&quot;20&quot;></td>
</tr>
<tr>
<td ALIGN=&quot;right&quot;>Password:</td>
<td><input TYPE=&quot;password&quot; NAME=&quot;password1&quot; size=&quot;20&quot;></td>
</tr>
<tr>
<tr>
<td ALIGN=&quot;right&quot;>Repeat password:</td>
<td><input TYPE=&quot;password&quot; NAME=&quot;password2&quot; size=&quot;20&quot;></td>
</tr>
<tr>

<td ALIGN=&quot;right&quot;></td>
<td>
<input TYPE=&quot;submit&quot;>
<input TYPE=&quot;reset&quot;> </td>
</tr>
</table>
</form>
</body>
</html>

Best regards,

I agree with IR. The validation should be done on your HTML page form BEFORE it is submitted to your ASP page. That way, the validation is done client side, and should be quicker than submitting the information and then having to deal with invalid information.
