I need to create the upload process where the user can upload multiple files at once, using the file field with html5 multiple attr. Name of the file must be saved in the associated model.
I can run successfully upload one file and save the file name in the photos table, across the field:
echo $this->Form->file('photos.name');
But if I want to enable upload more photos with
echo $this->Form->input('title'); // post title
echo $this->Form->input('maintext'); // post main text,
... etc
echo $this->Form->file('photos[].name',['multiple'=>true]);
I get into the problem, and try to understand where I make mistakes, but without success.
PostsController:
public function add()
{
$post = $this->Posts->newEntity();
if ($this->request->is('post')) {
$post = $this->Posts->patchEntity($post, $this->request->data);
if ($this->Posts->save($post)) {
$this->Flash->success(__('The post has been saved.'));
return $this->redirect(['action' => 'index']);
} else {
$this->Flash->error(__('The post could not be saved. Please, try again.'));
}
}
$this->set(compact('post'));
$this->set('_serialize', ['post']);
}
PostsTable:
$this->addBehavior('Upload');
$this->hasMany('Photos', [
'foreignKey' => 'post_id'
]);
UploadBehavior
All standard callbacks where I currently perform debug $data / $entity, but only in beforeMarshal i use:
$data = Hash::get($data,'name');
debug($data);
// debug output
[
'name' => 'HPIM3869.JPG',
'type' => 'image/jpeg',
'tmp_name' => 'C:\xampp\tmp\phpF02D.tmp',
'error' => (int) 0,
'size' => (int) 1295448
],
...
In beforeSave and afterSave
My form is OK, the data properly come in before Marshal method, if I upload 3 files, I also see the same number of debug outputs, but in beforSave and afterSave debug only show the first file like this:
debug($entity);
object(App\Model\Entity\Photos) {
'name' => [
'name' => 'HPIM3435.JPG',
'type' => 'image/jpeg',
'tmp_name' => 'C:\xampp\tmp\php5839.tmp',
'error' => (int) 0,
'size' => (int) 1517410
],
'post_id' => (int) 469,
'created' => object(Cake\I18n\Time) {
'time' => '2015-10-07T09:22:44+0200',
'timezone' => 'Europe/Berlin',
'fixedNowTime' => false
},
'modified' => object(Cake\I18n\Time) {
'time' => '2015-10-07T09:22:44+0200',
'timezone' => 'Europe/Berlin',
'fixedNowTime' => false
},
'[new]' => true,
'[accessible]' => [
'*' => true
],
'[dirty]' => [
'name' => true,
'post_id' => true,
'created' => true,
'modified' => true
],
'[original]' => [],
'[virtual]' => [],
'[errors]' => [],
'[repository]' => 'Photos'
}
Edit:
In the purpose of the test, I create such a form:
echo $this->Form->input('name',['value'=>'zzz']);
echo $this->Form->input('photos.0.name',['value'=>'zzz']);
echo $this->Form->input('photos.1.name',['value'=>'hhh']);
echo $this->Form->input('photos.2.name',['value'=>'fff']);
Also it only be saved the first result.
I need help to understand how to save multiple form data. Where I go wrong?
I think your field should be like this
echo $this->Form->file('photos.name.',['multiple'=>true]); //note dot notation at end of name. It will generate input name as array

I have a table that looks like this:
,====,==============,============,==========,
| id | contact_from | contact_to | message |
|====|==============|============|==========|
| 1 | 1 | 2 | some msg |
| 2 | 2 | 1 | reply |
'----'--------------'------------'----------'
I create a new row, doing this:
public function add()
{
$message = $this->Messages->newEntity();
if ($this->request->is('post') && $this->request->is('ajax')) {
$data = $this->request->getData();
$data['contact_to'] = (int)$data['contact_to'];
$data['contact_from'] = (int)$this->Auth->user('id');
$message = $this->Messages->patchEntity($message, $data);
if ($this->Messages->save($message)) {
echo json_encode(['status' => 'success']);
exit;
}
echo json_encode(['status' => 'error']);
exit;
}
}
And this is my hasOne association:
$this->hasOne('ContactFrom', [
'className' => 'Contacts',
'foreignKey' => 'id',
'bindingKey' => 'contact_from',
'joinType' => 'INNER',
'propertyName' => 'contact_from'
]);
$this->hasOne('ContactTo', [
'className' => 'Contacts',
'foreignKey' => 'id',
'bindingKey' => 'contact_to',
'joinType' => 'INNER',
'propertyName' => 'contact_to'
]);
As you can see, I pass an ID to a new row, however it saves everything, except the id's. When I debug($message) after the patchEntity call, it comes back like this:
object(App\Model\Entity\Message) {
'message' => 'asdfasdf',
'date_sent' => object(Carbon\Carbon) {},
'[new]' => true,
'[accessible]' => [
'contact_to' => true,
'contact_from' => true,
'message' => true,
],
'[dirty]' => [
'message' => true,
],
'[original]' => [],
'[virtual]' => [],
'[errors]' => [],
'[invalid]' => [],
'[repository]' => 'Messages'
}
It drops my ID's. I assume it's because I need to pass the Entity to it, but to save on db calls, how can I make it save the contact_to and contact_from id's to the table?
The names that you've choosen are causing a clash in the marshaller.
You cannot use the same name for the binding/foreign key and the property name, these two need to be different, as the former are ment to hold an identifier, and the latter is ment to hold either an entity, or an array that can be marshalled into an entity - neither of that applies to the value that you are passing, hence it will be discard.
You should ideally follow the CakePHP naming conventions, and append _id to your columns, ie name them contact_from_id and contact_to_id.

I use BlueImp jQuery plugin to upload multiple images in follow scenario:
User open add or edit Albums page, select images and procces upload via ajax method. This work fine, image data (name, size, model, field,..) are stored in related images table without foreign key.
Ajax return id of recent uploaded image, and js create (captions, position) inputs for that file.
User fill other form fields, and click submit.
Problem, if user create new album or edit/update exist one wich not contain images, application does not update foriegn key for new images. But if album contain images, and user add new one to album, after save post cakephp add / update foreign key to new images records.
Debug output:
// first time add images, does not update FK
[
'name' => 'A4',
'images' => [
(int) 116 => [
'caption' => '',
'position' => '1',
'id' => '116'
]
],
'id' => '4',
'user_id' => '1',
'active' => '1'
]
// album has one image, we add new one, CakePHP Update FK for new images
[
'name' => 'A4',
'images' => [
(int) 117 => [
'caption' => '',
'position' => '1',
'id' => '117'
],
(int) 118 => [
'caption' => '',
'position' => '2',
'id' => '118'
]
],
'id' => '4',
'user_id' => '1',
'active' => '1'
]
AlbumsController add method:
public function add()
{
$album = $this->Albums->newEntity();
if ($this->request->is('post')) {
$album = $this->Albums->patchEntity($album, $this->request->data,['associated' => ['Images']]);
if ($this->Albums->save($album)) {
$this->Flash->success(__('The album has been saved.'));
return $this->redirect(['action' => 'index']);
} else {
$this->Flash->error(__('The album could not be saved. Please, try again.'));
}
}
$users = $this->Albums->Users->find('list', ['limit' => 200]);
$this->set(compact('album', 'users'));
$this->set('_serialize', ['album']);
}
Albums Table:
$this->hasMany('Images', [
'foreignKey' => 'foreign_key',
'conditions' => [
'Images.model' => 'Albums',
'Images.field' => 'upload'
],
'sort' => ['Images.position' => 'ASC']
]);
Images Table:
$this->belongsTo('Albums', [
'foreignKey' => 'foreign_key',
'joinType' => 'INNER'
]);
I use same approach in the cakephp 2 apps, and work without problems.

Q: How to update foreignKey?
I'm not sure is this correct way, but it's work for me.
AlbumsTable
public function afterSave(Event $event, Entity $entity, ArrayObject $options)
{
if (isset($entity)) {
$images = TableRegistry::get('Images');
$images->query()
->update()
->set(['foreign_key' => $entity->id])
->where([
'foreign_key IS NULL',
'model' => 'Albums'
])
->execute();// conditions
}
}
I'm having the hardest time with saving multiple records. I've tried a million things, but I end up with the same problem: my records are not saved and I can't see any errors. Bear in mind that I'm new to cakephp and a novice coder.
Am I missing something obvious and crucial?
Table:
$this->table('splits');
$this->displayField('id');

$this->belongsTo('Accounts', [
'foreignKey' => 'account_credit_id',
'joinType' => 'INNER'
]);
Controller:
$splits = $this->Splits->newEntity();
if ($this->request->is('post')) {
$splits = $this->Splits->newEntities($this->request->data());
debug($splits);
foreach ($splits as $split){
$this->Splits->save($split);
}
}
$transactions = $this->Splits->Transactions->find('list', ['limit' => 200]);
$accounts = $this->Splits->Accounts->find('list', ['limit' => 200]);
$this->set(compact('split', 'transactions', 'accounts'));
$this->set('_serialize', ['split']);
Template:
echo $this->Form->input('Splits.1.transaction_id', ['options' => $transactions]);
echo $this->Form->input('Splits.1.amount', ['type' => 'float']);
echo $this->Form->input('Splits.1.account_id', ['options' => $accounts]);
echo $this->Form->input('Splits.2.transaction_id', ['options' => $transactions]);
echo $this->Form->input('Splits.2.amount', ['type' => 'float']);
echo $this->Form->input('Splits.2.account_id', ['options' => $accounts]);
echo $this->Form->input('Splits.3.transaction_id', ['options' => $transactions]);
echo $this->Form->input('Splits.3.amount', ['type' => 'float']);
echo $this->Form->input('Splits.3.account_id', ['options' => $accounts]);
Debug on $splits:
[
(int) 0 => object(App\Model\Entity\Split) {
(int) 1 => [

Did you somewhere saw this Table.index.field style being used, or did you just tried something and hoped it would work?
When saving many records respectively creating many entities, the expected format is a numerically indexed array that holds the data for the individual records, just as shown in the docs
Cookbook > Database Access & ORM > Saving Data > Converting Multiple Records
When creating forms that create/update multiple records at once you
can use newEntities():
[...]
In this situation, the request data for multiple articles should look
like:
$data = [
[
'title' => 'First post',
'published' => 1
],
[
'title' => 'Second post',
'published' => 1
],
];
So your inputs should not use the table name, but just the index and the field name, like
echo $this->Form->input('0.transaction_id', /* ... */);
echo $this->Form->input('0.amount', /* ... */);
echo $this->Form->input('0.account_id', /* ... */);
echo $this->Form->input('1.transaction_id', /* ... */);
echo $this->Form->input('1.amount', /* ... */);
echo $this->Form->input('1.account_id', /* ... */);
echo $this->Form->input('2.transaction_id', /* ... */);
echo $this->Form->input('2.amount', /* ... */);
echo $this->Form->input('3.account_id', /* ... */);
Try this:
$splits = TableRegistry::get('splits');
$entities = $splits->newEntities($this->request->data());
foreach ($entities as $entity) {
$splits->save($entity);
}
Try this example to insert multiple recored in cakphp 3.x
$passwords = $this->request->data('password_id');
foreach ($passwords as $password) {
$data = [
'event_id' => $this->request->data('event_id'),
'password_id' => $password
];
$eventPasswordAll = $this->EventPasswordAll->newEntity();
$this->EventPasswordAll->patchEntity($eventPasswordAll, $data);
$this->EventPasswordAll->save($eventPasswordAll );}
I hope it is useful to your question
please reviwe it, Thanks !
If you’d like to process all the entities as a single transaction you can use transactional():
Although using a loop, "transations" avoids errors if the "save" does not work.
// In a controller.
$articles->getConnection()->transactional(function () use ($articles, $entities) {
foreach ($entities as $entity) {
$articles->save($entity, ['atomic' => false]);
}
});
Converting Multiple Records - CakePHP 3
I am trying to use CakePdf to generate a pdf file within CakePHP. I have a function in the CourseGradesController called viewReport. I want viewReport to allow you to select a student from a select field, and then upon submitting the form, it will generate a PDF with the appropriate data. If I put the data into a table and do not try to make a PDF, the page will display correctly, so I don't think that is the problem. In bootstrap.php, I have
CakePlugin::load('CakePdf', array('bootstrap' => true, 'routes' => true));
Configure::write('CakePdf', array(
'engine' => 'CakePdf.WkHtmlToPdf',
'options' => array(
'print-media-type' => false,
'outline' => true,
'dpi' => 96
),
'margin' => array(
'bottom' => 15,
'left' => 50,
'right' => 30,
'top' => 45
),
'binary' => '/var/www/cakephp/app/Plugin/CakePdf/Vendor/WkHtmlToPdf',
'orientation' => 'landscape',
'download' => false
));
I have the WkHtmlToPdf folder moved into /var/www/cakephp/app/Plugin/CakePdf/Vendor/WkHtmlToPdf, so the lib and include folders are in that directory.
In the viewReport function of CourseGradesController, I have
function viewReport($id = null)
{
$this->CourseGrade->id = $id;
if (!$this->CourseGrade->exists())
{
throw new NotFoundException(__('Invalid invoice'));
}
$this->pdfConfig = array(
'orientation' => 'portrait',
'filename' => 'Invoice_' . $id
);
$this->set('invoice', $this->CourseGrade->read(null, $id));
...
}
If I navigate to /courseGrades/viewReport, I get the error "Error: The requested address '/cakephp/courseGrades/viewReport' was not found on this server."
If I naviate to /courseGrades/viewReport/1.pdf, then I just see a completely blank screen.
I would strongly recommend the use of this plugin for this kind of work.

For some reason my allowed_values_function never gets called when showing a field on a user bundle. Code:
function get_business_units()
{
$options = entity_load('business_unit', FALSE, NULL, FALSE);
$opt = bu_to_list_values($options);
return $opt;
}
function MYMODULE_enable()
{
if (!field_info_field('field_user_business_unit')) {
$field = array(
'field_name' => 'field_user_business_unit',
'type' => 'text',
'settings' => array(
'allowed_values' => array(),
'allowed_values_function' => 'get_business_units',
)
);
field_create_field($field);
// Create the instance on the bundle.
$instance = array(
'field_name' => 'field_user_business_unit',
'entity_type' => 'user',
'label' => 'Business Unit',
'bundle' => 'user',
'required' => FALSE,
'settings' => array(
'user_register_form' => 1,
),
'widget' => array(
'type' => 'options_select',
),
);
field_create_instance($instance);
}
}
The field is created, and even displayed on the users "edit" page when editing their info. But the only value is "Select" or "None". My method is never called (I even placed a debug point). This is all in MYMODULE.install file.
The problem is: 'type' => 'text'.
You have to use: 'type' => 'list_text'.
Allowed values is meaningless for a text type.
Your get_business_units() function needs to be in the MYMODULE.module file; the .install files aren't included in a normal Drupal bootstrap.
Have you tried
drush features-revert MYMODULE ?
