I am having trouble figuring out how to attach an uploaded image to a node in my form submit handler. I've been searching for a while now and nothing I've tried has worked. For instance:

$image = $form_state['storage']['image'];
unset($form_state['storage']['image']);
$image->status = FILE_STATUS_PERMANENT;
$file = file_save($image);
$node->field_image['und'][0] = $file;

does not work.

Any help on this would be much appreciated. Thanks.

  • If I recall correctly you need $node->field_image['und'][0] = (array) $file; and then you need to call node_save($node); after that.

  • @Jaypan I have tried that as well. I've been at this for over an hour, and have tried basically everything on Google.

  • @Jaypan Well, first off, I get "undefined index storage" so I've replaced that with ["values"]["image"]. But the uploaded image does not get attached to the node. I've tried a var_dump($form_state['values']['image']) (as well as ['storage']), but that gives me an empty string. And no matter what I do, I don't get an image attached to the node.

    What is the form element defined as? If it's type 'file', then the uploaded data will be part of the $_FILES global. Usually it's better to create the element as type 'managed_file' though, in which case the value in the submit will be the file ID of the uploaded file, and you don't need to touch the $_FILES global.

It's been a while since I've done this but this link should be a good start. File Load

Assuming $form_state['storage']['image'] is the image's fid, what you may want to do is. 

$image = $form_state['storage']['image'];
$file = file_load($image);

// Change status to permanent.
$file->status = FILE_STATUS_PERMANENT;

// Save.
file_save($file);

// add image back
$node->field_image['und'][0] = $image;

Depending on what your doing you may want to add the file to the usage table. Details here. File Usage Add

    Thank you. This finally worked after switching to 'managed_file' as the type.

  • No problem, I forgot about that being necessary. Glad you worked it out.
