I am trying to display data from a database based on the logged in user in laravel.
If there is data for one user everything works well but if another user adds data to the table I get the error Cannot use object of type stdClass as array
Here is how I am getting the data in controller
public function viewBookings() {
$allProducts = Booking::get()->where('client', Auth::user()->name);
$products = json_decode(json_encode($allProducts));
foreach ($products as $key => $val) {
$service_name = Service::where(['id' => $val->service])->first();
$service_fee = Charge::where(['id' => $val->charge])->first();
$service_status = Status::where(['id' => $val->status])->first();
$products[$key]->service_name = $service_name->name;
$products[$key]->service_fee = $service_fee->total;
$products[$key]->service_status = $service_status->name;
}
return view('client.booking.view_bookings')->with(compact('products'));
}
The error is indicated at this line
$products[$key]->service_name = $service_name->name;
I have tested it by deleting the data for the other user and all works fine but If I return the other users data to the table I get that error
I would suggest removing this line
$products = json_decode(json_encode($allProducts));
and simply use
$products = $allProducts;
since what you are doing with the json_decode is the one creating the problems

I needed to to add / update field collections to node entities without updating the node entities. I tried two ways listed in https://www.drupal.org/node/1842304 and http://alexrayu.com/blog/saveupdate-field-collection-without-nodesave but none of them seems to be working exactly the way I want.
I tried as follows:
$node = node_load($nid);
$field_collection_item = entity_create('field_collection_item', array('field_name' => 'field_college_rating_data'));
$field_collection_item->setHostEntity('node', $node);
$field_collection_item->field_text1['und'][0]['tid'] = $form_state['input']['field_text1']['und'];
$field_collection_item->field_text2['und'][0]['value'] = $form_state['input']['field_text2']['und'];
$field_collection_item->save();
It added a field collection but it updates the node.
I also tried to alter the field collection form submit and used custom submit handler as follows:
function own_custom_field_collection_submit($form,$form_state) {
$field_collection_item = field_collection_item_form_submit_build_field_collection($form, $form_state);
$field_collection_item->save(TRUE);
drupal_set_message(t('The changes have been saved.'));
$form_state['redirect'] = $field_collection_item->path();
}
I have copied this code from core field collection module to change the default argument to "TRUE" in the save function. It added the field collection but didn't associated with the parent node.
I need to save the field collection separately since my node entity form is very large with 50 to 60 fields and field collections and I don't want to update it as many times as I add / update any field collections to the node.
Any help will be much appreciated.
Thanks
You have to pragmatically relate your field collection to the host entity by the following code.
$field_collection_item = field_collection_item_form_submit_build_field_collection($form, $form_state);
$field_collection_item->save(TRUE);
$host_entity = $field_collection_item->hostEntity();
$lang = 'und';
if (isset($host_entity->nid) && isset($host_entity->vid) && isset($lang) && isset($field_collection_item->item_id) && isset($field_collection_item->revision_id)) {
$query = db_select('field_data_field_text1', 'fd');
$query->addExpression('max(fd.delta)', 'total_row');
$query->condition('fd.entity_id', $host_entity->nid);
$max_delta = $query->execute()->fetchField();
if (isset($max_delta)) {
$max_delta = $max_delta + 1;
} else {
$max_delta = 0;
}
db_insert('field_data_{field_collection}')->fields(array(
'entity_type' => 'node',
'bundle' => '{node_type}',
'entity_id' => $host_entity->nid,
'revision_id' => $host_entity->vid,
'language' => $lang,
'delta' => $max_delta,
'field_text' => $field_collection_item->item_id,
'field_text_revision_id' => $field_collection_item->revision_id
))
->execute();
}
Replace your content type and field type in { } and then you just have your field collection relate to your host entity.
Thanks
I am trying to modify a field collection in a node that already exists so I can change an image on the first element in an array of 3. The problem is, the hostEntity info is not set when I do a entity_load or entity_load_single so when I do a:
$field_collection_item->save(true); // with or without the true
// OR
$fc_wrapper->save(true); // with or without the true
I get the following error:
Exception: Unable to save a field collection item without a valid reference to a host entity. in FieldCollectionItemEntity->save()
When i print_r the field collection entity the hostEntity:protected fields are indeed empty. My field collection is setup as follows:
field_home_experts
Expert Image <--- Want to change this data only and keep the rest below
field_expert_image
Image
Expert Name
field_expert_name
Text
Expert Title
field_expert_title
Text
Here is the code I am trying to use to modify the existing nodes field collection:
$node = getNode(1352); // Get the node I want to modify
// There can be up to 3 experts, and I want to modify the image of the first expert
$updateItem = $node->field_home_experts[LANGUAGE_NONE][0];
if ($updateItem) { // Updating
// Grab the field collection that currently exists in the 0 spot
$fc_item = reset(entity_load('field_collection_item', array($updateItem)));
// Wrap the field collection entity in the field API wrapper
$fc_wrapper = entity_metadata_wrapper('field_collection_item', $fc_item);
// Set the new image in place of the current
$fc_wrapper->field_expert_image->set((array)file_load(4316));
// Save the field collection
$fc_wrapper->save(true);
// Save the node with the new field collection (not sure this is needed)
node_save($node);
}
Any help would be greatly appreciated, I am still quite new to Drupal as a whole (end-user or developer)
Alright so I think I have figured this out, I wrote up a function that will set a field collection values:
// $node: (obj) node object returned from node_load()
// $collection: (string) can be found in drupal admin interface:
// structure > field collections > field name
// $fields: (array) see usage below
// $index: (int) the index to the element you wish to edit
function updateFieldCollection($node, $collection, $fields = Array(), $index = 0) {
if ($node && $collection && !empty($fields)) {
// Get the field collection ID
$eid = $node->{$collection}[LANGUAGE_NONE][$index]['value'];
// Load the field collection with the ID from above
$entity = entity_load_single('field_collection_item', array($eid));
// Wrap the loaded field collection which makes setting/getting much easier
$node_wrapper = entity_metadata_wrapper('field_collection_item', $entity);
// Loop through our fields and set the values
foreach ($fields as $field => $data) {
$node_wrapper->{$field}->set($data);
}
// Once we have added all the values we wish to change then we need to
// save. This will modify the node and does not require node_save() so
// at this point be sure it is all correct as this will save directly
// to a published node
$node_wrapper->save(true);
}
}
USAGE:
// id of the node you wish to modify
$node = node_load(123);
// Call our function with the node to modify, the field collection machine name
// and an array setup as collection_field_name => value_you_want_to_set
// collection_field_name can be found in the admin interface:
// structure > field collections > manage fields
updateFieldCollection(
$node,
'field_home_experts',
array (
'field_expert_image' => (array)file_load(582), // Loads up an existing image
'field_expert_name' => 'Some Guy',
'field_expert_title' => 'Some Title',
)
);
Hope this helps someone else as I spent a whole day trying to get this to work (hopefully I won't be a noob forever in Drupal7). There may be an issue getting formatted text to set() properly but I am not sure what that is at this time, so just keep that in mind (if you have a field that has a format of filtered_html for example, not sure that will set correctly without doing something else).
Good luck!

I was still getting the error, mentioned in the question, after using the above function.
This is what worked for me:
function updateFieldCollection($node, $collection, $fields = Array(), $index = 0) {
$eid = $node->{$collection}[LANGUAGE_NONE][$index]['value'];
$fc_item = entity_load('field_collection_item', array($eid));
foreach ($fields as $field => $data) {
$fc_item[$eid]->{$field}[LANGUAGE_NONE][0]['value'] = $data;
}
$fc_item[$eid]->save(TRUE);
}
I hope this helps someone as it took me quite some time to get this working.
I am trying to write a function that will get me the names of the required fields from the drupal database. Then, so I can write one validation function for alerting the user that he/she has not entered in a required field.
You can get this quite easily using the field_info_instances() function:
$instances = field_info_instances('node', 'invoice');
$required = array();
foreach ($instances as $field_name => $instance) {
if ($instance['required'] == 1) {
$required[] = $field_name;
}
}
To get the field type you need to query for the field not the instance. In the loop you can call:
$field = field_info_field($field_name);
$type = $field['type'];
I'm stuck on a problem that I've researched for several days with no luck and the answers here are usually spot on.
I have custom module code that adds a node from form supplied data:
$edit = array();
$edit['uid'] = $user->id;
$edit['name'] = $user->name;
$edit['status'] = 1;
$edit['taxonomy'] = array($term_id);
$edit['title'] = $Title;
$edit['body'] = $body;
etc...
and then saved with:
node_invoke_nodeapi($edit, $nType);
node_validate($edit);
if ($errors = form_get_errors()) {
print_r($errors);
}
$node = node_submit($edit);
node_save($node);
This all works perfectly. But I'm trying to add location data to each node based on a supplied (sanitized) zip field.
I have gmap and location modules installed and working. When I add the zip directly using the drupal content editor it all works. Even the views gmap. So i know versions and mods are all correct.
I've used this:
$location = array(
'country' => 'US',
'postal_code' => $zip,
);
$locationID = location_save($location);
and this:
$location['country'] = "US";
$location['postal_code'] = $zip;
$locationID = location_save($location);
with and without the country element.
And then in the node data init section (above) this:
$edit->locations[0]['lid'] = $locationID;
or
if($locationID) $edit['field_location'][0]['lid'] = $locationID;
or
if($locationID) $edit['location'][0]['lid'] = $locationID;
But none of this works. The submit will go through ok actually but no location data is saved. And no errors thrown.
Any help with this would be greatly appreciated.
I did get this to work, (in case anyone is having the same issue and stumbles upon this), by creating the node first and then adding the location data to the node with:
$locations = array();
$locations[0]['postal_code'] = $zip;
$criteria = array();
$criteria['nid'] = $node->nid;
$criteria['vid'] = $node->vid;
$criteria['genid'] = 'NAME OF NODE TYPE HERE';
location_save_locations( $locations, $criteria );
I guess location_save_locations is the correct way of doing it, not location_save.
Following your approach, as exposed by the wider location_save_locations() at line 4, you can update a location with location_save($locations[$key], TRUE, $criteria).
A few notes:
location_save return the lid of the saved location, or FALSE if the location is considered "empty."
Clean your cache or query the database ( mysql> SELECT * FROM location ORDER BY lid DESC limit 6 ) for a fresh view of the new entity location (ie: node_load data may be cached).
Alternatively, if you are handling an entity with a location field, you may try something cleaner like:
// Updated the location.
$node->field_location['und'][0] = $location;
// Save the node.
node_save ($node);
I needed to create a custom select list for the user registration page that pulls a SQL query from nodes I need to link to users. I have successfully accomplished this task.. :)
However, when I submit the value, I can't seem to control where the value is stored. In fact, I can't store the value at all. I have created a custom field for my value, but only the new field name is stored, and it is serialized and stored in the Data column of the user table.
Below is my code, I've commented my issues in it. Any help would be appreciated!
<?php
// $Id$
//create the additional user form field, a select list named "account_name"
//then calls the next function to populate it.
function accountselect_user($op, &$edit, &$account, $category = NULL) {
if ($op == 'register' || 'edit')
$fields['Information']['account_name'] = array(
'#type' => 'select',
'#title' => 'Account',
'#description' => t('Select the account to which the contact belongs'),
'#options' => accountselect_getclubs() ,
);
return $fields;
}
//contains query to pull results to select list...this part is working
function accountselect_getclubs() {
$return = array();
$sql = 'SELECT DISTINCT `title` FROM node WHERE type = \'accounts\' ';
$result = db_query($sql);
while ($row = db_fetch_array($result)) {
$return[] = $row['title'];
}
return $return;
}
//CAN'T GET THIS PART TO WORK - query to update the row - the uid = 29 is for
//testing puposes. Once I get the test value to work
//the test value I will worry about updating the correct user.
function accountselect_submitaccount() {
$sql = "UPDATE users SET account = \'value\' WHERE uid = \'29\'";
db_query($sql);
drupal_set_message(t('The field has been updated.'));
}
//I SUSPECT THE PROBLEM IS HERE...call the submitaccount function.
//I have tried hook_form_alter as well...
function accountselect_submit(&$form, &$form_state) {
if($form_id == 'user-register')
drupal_execute('accountselect_submitaccount');
}
Have you checked Drupal's logs? It should be throwing errors, as this is not a valid query.
$sql = "UPDATE users SET account = \'value\' WHERE uid = \'29\'";
Should be:
$sql = "UPDATE users SET account = 'value' WHERE uid = '29'";
Additionally, in:
function accountselect_submit(&$form, &$form_state) {
if($form_id == 'user-register')
drupal_execute('accountselect_submitaccount');
}
$form_id is never defined.
You say you've created the field in the database, but it must match the name of the Drupal field to be automatically handled. You've got two different names for it - account_name in the Drupal field, but account in the database. Make them consistent and it should be automatically handled, no submit functions required.
