Checkboxes [Archive]

Dec 3rd, 2000, 02:51 PM

Okay, so I have this site where it displays the working directories files with a checkbox for each file. If you check the box and hit "delete" it deletes the file from the server (kinda like geocities file manager). Does anyone know how refferr to each of the CHECKED checkboxes and their names? Here's my code:

Music.asp

<%@ Language="VBScript" %>

<html>

<head>

<%

'Define the File System Object and set variables
'FSO = FileSystemObject

Dim FSO, Folder, FolderContents, FileItem
Set FSO = CreateObject("Scripting.FileSystemObject") 'Create FSO
Set Folder = FSO.GetFolder("C:\muzak\soul") 'Declare folder to have contents displayed
Set FolderContents = Folder.Files

%>

<title><%= Response.Write(Folder.Name) %></title>

<style type="text/css">

body, table {color:#000000; font-family:Verdana; font-size:11px}

</style>

</head>

<body background="/images/bground.gif" bgcolor="#ffffff" text="#000000" marginheight="0" topmargin="0">

<form action="Confirm.asp" method="post">
<table border="0" cellpadding="4" cellspacing="0">
<tr><td bgcolor="darkgray" align=left>
</td><td bgcolor="darkgray" align=left>
<font size="2"><b>File</b></font>
</td><td bgcolor="darkgray" align=left>
<font size="2"><b>Size (mb)</b></font>
</td></tr>

<%

'Display each file's name and size with a checkbox

Response.Write("<font size=5>Contents of: " & Folder & "<p>")

Dim FileSize

For Each FileItem In FolderContents
FileSize = Round(FileItem.Size / 1000000, 1) 'Converts file size into MB, rounds to tenth place
Response.Write("<tr><td bgcolor=lightgrey align=left>")
Response.Write("<input type=checkbox name=" & FileItem.Name & " value=" & FileItem.Name & ">")
Response.Write("</td><td bgcolor=lightgrey align=left>")
Response.Write(FileItem.Name) 'Displays file name
Response.Write("</td><td bgcolor=lightgrey align=right>")
Response.Write(FileSize) 'Displays file size in MB
Response.Write("</td></tr>")
Next

%>

</td></tr>
<tr><td colspan=3>
<input type="submit" value="Delete">
</td></tr>
</table>
</form>

</body>

</html>

-----------------------------------------------------------------------------------------------------------------------

Confirm.asp

<%@ Language="VBScript" %>

<html>

<head>
<title>Warning!</title>

<style type="text/css">

Dim Checked, FilesToDelete

Checked = 0 'Set number of checked to zero
For Each Checked In Request.Form
thisvalue = Request.Form(Checked)
If thisvalue = "on" Then

End If
If FilesToDelete > 1 Then
FileNum = "files"
Else
FileNum = "file"
End If
Next

<fotn size="3"><b>Are you sure that you want to delete the following <%= Response.Write(FileNum & "?") %></b></font>

<%

'Display all the files checked

Response.Write(thisvalue & "<br>")

%>

<input type="button" value="No, take me back" onClick="location='Music.asp'">
<input type="button" value="Yes, proceed" onClick="location='Delete.asp'">

I usually give them all the same name and refer to them by index in the collection.

Are you trying to access the checkboxes on server side or client side as the syntax is different...

But i want to delete the files that are coralated with the checked boxes...do you know what I mean? Only the ones that are checked get deleted. How would I set a collection up and then tie that into the orrigional files they represent?

I typically will put the unique identifier for the line into a hidden input tag and refer to it in the same manner (by index).

For me, that means putting the Primary Key into the input tag but you could just as easily put the filename in it.

If you have a group of the same tags repeated with a loop, you should give the tags the same name (same name for each row, not column of course) and refer to them by index. That also allows you to loop through the elements much easier than if they each had their own unique name.

how do I access them by index?
