Question

CFFILE Design Example

Asked by: jturkington

Advise on how to accomplish the following would be much appreciated: -

I have a new user form which adds in a users details, once entered this then moves to a second screen where the newly created users ID is stated at the top of the page eg..    USER09. On the 2nd page also is a file upload box with prompts the user to upload a word document.

What i want to achieve is the following : -

The user can only upload a word document that has the same name as there newly created ID eg USER09.doc
The file is to be stored to the webservers location c:\docs
An error is to be displayed top the user if the word documents name doesnt match with their userid

Any code on how to achieve this for the second page would be much appreciated


Cheers

JT

This is what i would do. Dont worry about the name of the file they are unloading.. it can be anything.. so you know how to get the file uploaded to the server..

for eg..

<cffile action="upload" filefield="formfield" destination="something" nameconflict="makeunique">
 <!--- this is where u wil rename the file --->

<cfset userfile = file.ServerFile>
<cffile action = "rename" source="expandPath(userfile)" destination="expandPath(user09.cfm)">

 

by: jturkingtonPosted on 2005-06-03 at 06:46:04ID: 14139489

Sorry didnt explain myself properly...

I need the user to physically name their word document to the name of their userid for validation  purposes. So there should be no renaming of the file at all.

If the uploaded word document doesnt match the userid - fail
No name duplications are allowed

Any code on how to perform this would be much appreciated

 

by: adonis1976Posted on 2005-06-03 at 07:55:04ID: 14140254

You can use some kind of javascript for this:

say onSubmit of the form, you have a validate function:

function validate() {
<cfoutput>
if (#listlast(form.formfile_filedname.value,"\") != '#new_username#.doc' ) {
alert ("rename ur file" );
return false;
}
</cfoutpur>
return true;
}

 

by: jturkingtonPosted on 2005-06-03 at 08:00:31ID: 14140317

I would prefer to use server side as javascript could be disabled..

Is it possible to : -

upload the file
perform filename validation check
delete file if error occurs

 

by: adonis1976Posted on 2005-06-03 at 08:06:05ID: 14140372

yeah something like this:

pass the user name as a hidden input ..

<cffile action="upload" filefield="formfield" destination="something" nameconflict="makeunique">
 <!--- this is where u wil rename the file --->

<cfset userfile = file.ServerFile>
<cfif userfile NEQ 'username.doc'>
<cffile action="delete" file="expandPath(userfile)">
<cfoutput>you did name the file properly </cfoutput>
</cfif>

 

by: Dain_AndersonPosted on 2005-06-03 at 08:11:03ID: 14140430

<cffile action="upload" filefield="formfield" destination="something" nameconflict="makeunique">

<CFSET RequiredName = "#Form.UserID#.doc">
<CFIF Compare(File.ClientFileName, RequiredFileName) NEQ 0>
    <!--- do something here, such as CFLOCATION back to the form --->
<CFELSE>
    <cffile  action="delete"  file="full_path_name">
</CFIF>

Dain's code is the first post that actually works as advertised.

Are you trying to make sure that the client doesn't forget their new ID?  Because I don't see any other function this filename check could perform, as it does nothing whatsoever to hinder a hacker.
