Updating multiple records with ASP

I'm trying to update all returned records at the same time, where the checkbox is checked.
Something is missing from my code; would you please let me know how I could update the AutoStatus field of each selected record?
<%
set conn=Server.CreateObject("ADODB.Connection")
conn.Provider="Microsoft.Jet.OLEDB.4.0"
conn.Open(Server.Mappath("/DB/Autos.mdb"))

set rs = Server.CreateObject("ADODB.recordset")
rs.Open "SELECT * FROM Auto_Table", conn
%>

<html>
<head>
<title>All Requests</title>
<SCRIPT LANGUAGE="JavaScript">
<!-- Begin
var checkflag = "false";
function check(field) {
if (checkflag == "false") {
for (i = 0; i < field.length; i++) {
field[i].checked = true;}
checkflag = "true";
}
else {
for (i = 0; i < field.length; i++) {
field[i].checked = false; }
checkflag = "false";
}
}
// End -->
</script>

</head>
<body>

<form name="editor" method="post" action="Approval_send.asp">

<table border="1">
<tr>
<th>Employee Name</th>
<th>Emp.#</th>
<th>Auto Status</th>
<th><input type="checkbox" onClick="this.value=check(this.form.ID)"></th>
</tr>
<%
if not (rs.EOF or rs.BOF) then rs.movefirst
do until rs.EOF
%>
<tr>
<td><%=rs("EmpName")%></td>
<td><%=rs("Emp_Id")%></td>
<td><%=rs("AutoStatus")%></td>
<td><input type="checkbox" name="ID" value="<%=rs("ID") %>"></td>
</tr>
<%
rs.MoveNext
loop
rs.Close
conn.Close
%>
</table>


<br /><br />
<select name="AutoStatus">
<option value="Pending">Select Status</option>
<option value="Disapproved">Disapproved</option>
<option value="Approved">Approved</option>
</select>

<input type="hidden" name="Pipa" value="&#252">
<input name="ApprovedBy" type="hidden" id="ApprovedBy" value="<%=Request.ServerVariables("LOGON_USER")%>" />
<input type="Submit" name="Submit" value="Update" />
</center>
</form>

</body>
</html>

Hi baxtalo,
Not sure on this, just looking quickly over your code but it looks like you are trying to update the values in the Javascrip client-side? You cnanot do that.

I would make this change...
do until rs.EOF
%>
<tr>
<td><%=rs("EmpName")%></td>
<td><%=rs("Emp_Id")%></td>
<td><%=rs("AutoStatus")%></td>
<td><input type="checkbox" name="ID_<%=rs("ID").Value%>" value="1"></td>
</tr>
<%
rs.MoveNext


Then in the receiving page set all checkflags to false. Then run through each request field name received and it begins with "ID_" then you get the ID number from the name by using RIGHT('<fieldname>',LEN(<fieldname>)-3) and set the value to true (I am assuming the database has the field as a true/false value.

Do you follow that? If not let me know and I can toss together a fast version of the 2 pages to show you.

DOH! I see what you are doing. You want to change them IN the HTML based on the top one.
Make this function in the Javascript:
function checkLikeMe($) {
    var x = document.getElementsByName('ID');
    for (var y = 0; y < x.length; y++)
        x[y].checked = $;
}

Now change the top input checkbox to:
<input type="checkbox" onClick="checkLikeMe(this.checked)">

That ought to do it for you.

One question... How are you going to know what record to update on the receiving end? I think you may not have that one yet. Do you need more code to do that as well?
