Cffunction adn cffile upload

[Guest]

Hello to everyone !

I have a problem to upload a file with cffunction :

i created a cfc with a function 'upload' :
<cffunction name="upload" access="remote" returntype="void">
<cfargument name="image_big" type="any" required="no">
<cffile action="upload" fileField="#arguments.image_big#" destination = "mylocation" nameConflict="overwrite" accept="image/*">
</cffunction>

but it doesn’t work with out submitting the form .. pleas help ..
thanks !

I believe you need to have the file submitted via a form if you want to use the <cffile action="upload" fileField=""> method of cffile. Otherwise, how will the server gain access to the file itself?
