5.7 file upload example? (working, but seems ‘sketchy’)

I have been watching the 5.6 tutorial videos and trying to translate 5.6 instructions into 5.7… but I am lost when it comes to uploading files.

I managed to get it working, but I am not very confident that this is the best/right way…

relevant parts of controller
<?php namespace Application\Controller\SinglePage ;
use Loader;
use PageController;
use Concrete\Core\File\Importer as Importer;
class MyImages extends PageController {     
        $form = Loader::helper('form');
public function update() {
         $fi = new Importer();
         $myFileObject = $fi->import($pathToFile,$nameOfFile);     

<form method="post" action="<?= $this->action('update') ?> " enctype="multipart/form-data">
File: <?= $form->file('myImage') ?>
<?= $form->submit('submit', 'Save') ?>

ok, I can confirm it's not completely correct because when I add


i get

Whoops \ Exception \ ErrorException (E_ERROR)
Call to undefined method Concrete\Core\File\Version::isError()
    // run when we call setAttribute(), instead of saving through the UI
    public function saveValue($obj)
    if (!is_object($obj)) {
    $obj = File::getByID($obj);
    $db = Loader::db();
    if (is_object($obj) && (!$obj->isError())) {
    $db->Replace('atFile', array('avID' => $this->getAttributeValueID(), 'fID' => $obj->getFileID()), 'avID', true);

sooo... now I'm completely lost :( I added the 'Image/File' attribute to the user.

I see that $fv is getting returned from concrete/src/File/Importer.php

if (!($fr instanceof File)) {
            // we have to create a new file object for this file version
            $fv = ConcreteFile::add($sanitizedFilename, $prefix, array('fvTitle' => $filename), $fsl);
            $fr = $fv->getFile();
    } else {
            // We get a new version to modify
            $fv = $fr->getVersionToModify(true);
            $fv->updateFile($sanitizedFilename, $prefix);
    return $fv;

So the $fv object is returned into $myFileObject, and the code in concrete/attributes/image_file/controller.php is clearly looking for isError
if (is_object($obj) && (!$obj->isError())) {

The only place I see isError defined is in concrete/src/File/File.hp
     * @deprecated
public function isError()    {
        return false;

So I do not understand why, if $fr is NOT an instance of File (which we know because it passes the “ if (!($fr instanceof File)) {“ condition, why is isError() being called? Or, in more simple terms… how do I fix this?

In general the importer code looks totally correct (apologies that we haven't gotten the updated docs for this but it should be very similar to 5.6.x):

I think the issue is that this is returning a \Concrete\Core\File\Version object, not a \Concrete\Core\File\File object. So $myFileObject isn't actually a file object. You pass this version object into the setAttribute() method, and it really ought to be a file object you pass.

Try this:

$file = $myFileObject->getFile();
$this->myUI->setAttribute('picture', $file);

Now, for developers' sanity we probably ought to detect whether you're passing in a file object or a version object, since we could handle both of them easily and the error that gets thrown isn't tremendously helpful, but I believe that's what's going on.

Thanks for the info...

def in the rigth directions... i no longer get an error, but nothign is saved... so s little bit closer but still not actually working.

Also, when I print_r($file), should I be seeing the entire session object? because that is what I see. was expecting some smaller.

public function update_data() {
        if ($this->myUI instanceof UserInfo) {
            $fs = FileSet::getByName('test garbage');
            $fsp = new Permissions($fs);
            $fsp = FilePermissions::getGlobal();
            if ($fsp->canAddFiles()) {
                $pathToFile = $_FILES['myImage']['tmp_name'];
                $nameOfFile = $_FILES['myImage']['name'];                
                $fi = new Importer();
                $myFileObject = $fi->import($pathToFile, $nameOfFile, true);
                if (is_object($myFileObject)) {
                    $file = $myFileObject->getFile();
//  with the following line, no error but nothing is saved to the attribute (but the file is uploaded into FM
                    $this->myUI->setAttribute('favorite_picture', $file);
//  with the following line, "Call to undefined method Concrete\Core\File\Version::isError() "

That's really strange. I just tried this using a setAttribute call on a user info object with a file object and it worked. This will only work with the first line of code in your example, not the second.

I would try adding some debug code and exit; into the concrete/attributes/file/controller.php "saveValue" method. That method is one of the last run to insert the actual association between the file object and the attribute.
