validating files

[FSonaglioni]

Hi , how can i validate if a user attaches a valid type of&nbsp;&nbsp;file using an &lt;input type=file?&gt; , cause if i submit the form&nbsp;&nbsp;and that field is empty&nbsp;&nbsp;it returns me a message error when triying to upload the file! <br><br>and then using a &lt;cffile&gt; how could i rename this file (because using cfffile with the option &quot;MAKEUNIQUE&quot; )generates a unique filename for the upload .<br><br>Thanks in advance!!

You can set the ACCEPT parameter to the mime type of the type of file you want, like<br><FONT FACE=monospace><b><br>&lt;CFFILE ACTION=&quot;Upload&quot; FILEFIELD=&quot;TheFile&quot; DESTINATION=&quot;c:\web\uploads\&quot; ACCEPT=&quot;text/html&quot; NAMECONFLICT=&quot;MakeUnique&quot;&gt;<br></b></font><br>If you do not want to use the ACCEPT parameter (you just want to check an extension, you could do something like:<br><FONT FACE=monospace><b><br>&lt;CFFILE ACTION=&quot;Upload&quot; FILEFIELD=&quot;TheFile&quot; DESTINATION=&quot;c:\web\uploads\&quot; NAMECONFLICT=&quot;MakeUnique&quot;&gt;<br><br>&lt;cfif file.ClientFileExt is &quot;htm&quot; or file.ClientFileExt is &quot;html&quot;&gt;<br><br>&nbsp;&nbsp;&lt;cfset filename=file.ServerFile&gt;<br>&nbsp;&nbsp;&lt;cfset directoryname=file.ServerDirectory&gt;<br><br>&nbsp;&nbsp;&lt;cfif file.FileWasRenamed&gt;<br>&nbsp;&nbsp;&nbsp;&nbsp;&lt;cfset cfilename=file.ClientFileName&gt;<br>&nbsp;&nbsp;&nbsp;&nbsp;&lt;cfset cfileext=file.ClientFileExt&gt;<br>&nbsp;&nbsp;&nbsp;&nbsp;&lt;cffile action=&quot;rename&quot; source=&quot;#directoryname#\#filename#&quot; destination=&quot;#directoryname#\#cfilename#1.#cfileext#&quot;&gt;<br>&nbsp;&nbsp;&lt;/cfif&gt;<br><br>&lt;cfelse&gt;<br><br>&nbsp;&nbsp;&lt;cffile action=&quot;delete&quot; file=&quot;#directoryname#\#filename#&quot;&gt;<br><br>&lt;/cfif&gt;<br></b></font><br>There is one problem with this code in that if you upload a file called file.htm and it already exists, it will be renamed file1.htm whether or not file1.htm already exists.&nbsp;&nbsp;You should probably do a more thorough check for this condition....<br><br>Also, I can't remember off the top of my head whether file.serverdirectory returns the path with a trailing backslash or not.&nbsp;&nbsp;If it does, you should take the backslashes out...<br><br>Hope this helps.
