Here, you have to make sure the step with the upload, actually keep track of the uploaded file. What I use is a new index in the controller container. For example: $data =& $controller->container(); $data['uploads']['user_image'] = $filename; In the process action (used when the form is finished), I check if there is something in the 'upload' container and insert the value found in the database. I also suggest you extend the 'direct' action, or whatever action you use to switch from one page to another, so that it takes care of the uploaded file if the submitted page is the one with the upload. For example: If ($pagename == 'upload_page') { // Save the uploaded file and fill in the upload container } The above explanations are not related directly to your problem but they will probably help you. I'll add an example for handling uploads to the docs as soon as I can. > I've tried the following Code: > $file =& $this->addElement('file', 'pic1', 'Your > Pictore:'); > $this->addRule('pic1', 'Not an image', 'function', > 'CheckImage', > 'validation'); > > But validation::CheckImage() is never executed.

CheckImage is probably the right way to go if your function works. You maybe forgot to register the function before using it: function checkImage($elName, $value, $options = null) { return true; } $this->registerRule('checkimage', 'function', 'checkImage'); $this->addRule('pic1', 'Not an image', 'checkimage'); Good luck, Bertrand Mansion Mamasam
