Uploading and saving a file programmatically to Drupal nodes - drupal

Question

I am trying to create a node based on a custom form submission. Everything works great except for the images that get uploaded.
I can capture them fine and set them in the form object cache. When I pass the data into the function to create the node, I get this error:
"The specified file could not be copied, because no file by that name exists. Please check that you supplied the correct filename."
I also receive the error multiple times, despite only submitting one or two images at a time.
Here is the code I am using. $uploads is passed in and is an array of file objects returned from file_save_upload() in a previous step:
if (isset($uploads)) {
foreach ($uploads as $upload) {
if (isset($upload)) {
$file = new stdClass;
$file->uid = 1;
$file->uri = $upload->filepath;
$file->filemime = file_get_mimetype($upload->uri);
$file->status = 1;
$file = file_copy($file, 'public://images');
$node->field_image[$node->language][] = (array) $file;
}
}
}
node_save($node);
I also tried this:
if (isset($uploads)) {
foreach ($uploads as $upload) {
$upload->status = 1;
file_save($upload);
$node->field_image[$node->language][] = (array) $upload;
}
}
}
node_save($node);
The second causes a duplicate key error in MySQL on the URI field. Both of these examples I saw in tutorials, but neither are working?

For Drupal 7, I played around with this quite a bit and found the best way (and only way that I've got working) was to use Entity metadata wrappers
I used a managed file form element like so:
// Add file upload widget
// Use the #managed_file FAPI element to upload a document.
$form['response_document'] = array(
'#title' => t('Attach a response document'),
'#type' => 'managed_file',
'#description' => t('Please use the Choose file button to attach a response document<br><strong>Allowed extensions: pdf doc docx</strong>.'),
'#upload_validators' => array('file_validate_extensions' => array('pdf doc docx')),
'#upload_location' => 'public://my_destination/response_documents/',
);
I also pass along the $node object in my form as a value
$form['node'] = array('#type' => 'value', '#value' => $node);
Then in my submission handler I simply do the following:
$values = $form_state['values'];
$node = $values['node'];
// Load the file and save it as a permanent file, attach it to our $node.
$file = file_load($values['response_document']);
if ($file) {
$file->status = FILE_STATUS_PERMANENT;
file_save($file);
// Attach the file to the node.
$wrapper = entity_metadata_wrapper('node', $node);
$wrapper->field_response_files[] = array(
'fid' => $file->fid,
'display' => TRUE,
'description' => $file->filename,
);
node_save($node);
}

i used your code to upload a file in the file field to a content("document" in my case) and it's worked. Just had to add a value for field_document_file 'display' in the code.
here is the exact script i used:
<?php
// Bootstrap Drupal
define('DRUPAL_ROOT', getcwd());
require_once './includes/bootstrap.inc';
require_once './includes/file.inc';
drupal_bootstrap(DRUPAL_BOOTSTRAP_FULL);
// Construct the new node object.
$path = 'Documents/document1.doc';
$filetitle = 'test';
$filename = 'document1.doc';
$node = new StdClass();
$file_temp = file_get_contents($path);
//Saves a file to the specified destination and creates a database entry.
$file_temp = file_save_data($file_temp, 'public://' . $filename, FILE_EXISTS_RENAME);
$node->title = $filetitle;
$node->body[LANGUAGE_NONE][0]['value'] = "The body of test upload document.\n\nAdditional Information";
$node->uid = 1;
$node->status = 1;
$node->type = 'document';
$node->language = 'und';
$node->field_document_files = array(
'und' => array(
0 => array(
'fid' => $file_temp->fid,
'filename' => $file_temp->filename,
'filemime' => $file_temp->filemime,
'uid' => 1,
'uri' => $file_temp->uri,
'status' => 1,
'display' => 1
)
)
);
$node->field_taxonomy = array('und' => array(
0 => array(
'tid' => 76
)
));
node_save($node);
?>

Kevin, that's what I found in the Drupal doc's under http://drupal.org/node/201594 below in the comments. But I am not sure at all. I try the same, so please let me know what you found out.
$path = './sites/default/files/test.jpg';
$filetitle = 'test';
$filename = 'test.jpg';
$node = new StdClass();
$file_temp = file_get_contents($path);
$file_temp = file_save_data($file_temp, 'public://' . $filename, FILE_EXISTS_RENAME);
$node->title = $filetitle;
$node->uid = 1;
$node->status = 1;
$node->type = '[content_type]';
$node->language = 'und';
$node->field_images = array(
'und' => array(
0 => array(
'fid' => $file_temp->fid,
'filename' => $file_temp->filename,
'filemime' => $file_temp->filemime,
'uid' => 1,
'uri' => $file_temp->uri,
'status' => 1
)
)
);
$node->field_taxonomy = array('und' => array(
0 => array(
'tid' => 76
)
));
node_save($node);
