Hi,

Sorry if this is a dumb question, I'm new to this.

I have a form where i want the user to be able to upload an image from a form.  for the cffile i'm using

<cfif len(trim(form.ImageData))>

  <cffile action="upload"

     fileField="ImageData"

     destination="\uploads"

     nameConflict = "MakeUnique">

</cfif>

it works locally when i input the specific directory on my hard drive but when i use the above online i get an access denied error and it looks like it's trying to save it locally on c:\uploads

on my ftp i created an upload folder but I don't know what the 'destination' field typically looks like when you are trying to use cffile on a live site.  What information do i need from my web host to make this work? Like, does it involve an ip address?  I'm thinking some kind of username and password will be required.  does cffile have username password field too?  Basically, what shoudl cffile look like when you're using it ion a  live site

Thanks,

MIke

Here.. let's make this foolproof.  In your sites root folder, open the application.cfc, find the onRequestStart section and add the following:<cfset rootPath = "#REreplaceNoCase(ExpandPath('./'),'(.+[\\|\/]mymindsnotright.com\www)(.)+','\1','all')#" />This line will create a variable called rootPath, and no matter where in the folder structure the user goes, rootPath will always point to the root of the site.Then, depending upon where in your site the uploads folder is, you append that flow to t...

I think it has to be a fully-qualified filesystem path:

c:\directory\subdirectory\

Indeed, it does.  You need to put the full path from either the drive letter (C:\path\to\upload) on a Windows server, or /path/to/upload for a *nix server.  No relative paths allowed.

So, you could use ExpandPath('/') to find the current folder, and go from there.

This should work.

UPDATE: This will work IF the uploads folder is in the folder that the action page is in.

You don't need a username and password.  You need to know how the file structure is on the host server.

From the root of your site, where is the uploads folder?  Is it www.yoursite.com/uploads?  Is it www.yoursite.com/another/folder/then/uploads?

<cfset rootPath = "#REreplaceNoCase(ExpandPath('./'),'(.+[\\|\/]mymindsnotright.com\www)(.)+','\1','all')#" />

This line will create a variable called rootPath, and no matter where in the folder structure the user goes, rootPath will always point to the root of the site.

Then, depending upon where in your site the uploads folder is, you append that flow to the variable rootPath.

If it's /uploads, then the destination will be "#variables.rootPath#\uploads".

If it's /another/folder/uploads, then destination will be "#variables.rootPath#\another\folder\uploads".

That looks like you've messed up the structure for Application.cfc. You can't have anything after the closing cfapplication tag.

Dave meant "closing cfcomponent", of course. But I see that Wolf has also sorted that out with you in a later note.

If all this doesn't work (you point to the right path and STILL can't write to it), that will be yet another problem, about permissions. I'll share a separate note about that in a moment.

I would definitely contact tech support and ask them why access is denied.  That shouldn't be happening, unless they deny it for security purposes (as Charlie has pointed out).  In which case, they might have another folder for uploads.
