yet another upload script, however this time it let you control
some things that most script won't handle, for example it can
check images width and height.
upload script is attached in the zip file.
sample code using this upload script:
as you can see, in the Uploader code you can control theCode:<!-- #include file="ShadowUploader.asp" --> <% Dim objUpload If Request("action")="1" Then Set objUpload=New ShadowUpload If objUpload.GetError<>"" Then Response.Write("sorry, could not upload: "&objUpload.GetError) Else Response.Write("found "&objUpload.FileCount&" files...<br />") For x=0 To objUpload.FileCount-1 Response.Write("file name: "&objUpload.File(x).FileName&"<br />") Response.Write("file type: "&objUpload.File(x).ContentType&"<br />") Response.Write("file size: "&objUpload.File(x).Size&"<br />") Response.Write("image width: "&objUpload.File(x).ImageWidth&"<br />") Response.Write("image height: "&objUpload.File(x).ImageHeight&"<br />") If (objUpload.File(x).ImageWidth>200) Or (objUpload.File(x).ImageHeight>200) Then Response.Write("image to big, not saving!") Else Call objUpload.File(x).SaveToDisk(Server.MapPath("Uploads"), "") Response.Write("file saved successfully!") End If Response.Write("<hr />") Next Response.Write("thank you, "&objUpload("name")) End If End If %> <form action="<%=Request.ServerVariables( "Script_Name" )%>?action=1" enctype="multipart/form-data" method="POST"> File1: <input type="file" name="file1" /><br /> File2: <input type="file" name="file2" /><br /> File3: <input type="file" name="file3" /><br /> Name: <input type="text" name="name" /><br /> <button type="submit">Upload</button> </form>
maximum upload size (total of all files plus form data) and
the upload take place once you initialize the upload object.
however, the files will not be saved to disk until
SaveToDisk method is called!
you can check file type by ContentType or FileName, and you
can check if the file is valid image by checking the ImageWidth
or ImageHeight: if they're -1 it's not valid image.
- fixed file name problem - thanks Shem for pointing on this problem.
- fixed problem causing you could not use Response.Redirect
after you saved the uploaded files - thanks Shemzilla!
- changed the code so that passing new file name without
extension will use the original extension.
- changed the code so that it would append extension of
original file to the given fie name, if this given file name does
not have any extension.
