Image upload and display not work- Cakephp

I'm trying to add upload image for every connected user

But I can't upload to databse

Error message :

Cannot convert value of type array to string

Edit : When I try update The User profile from (profile function) I get message :
Notice (8): Uninitialized string offset: 0 [COREsrcViewHelperUrlHelper.php, line 174]

But when I update the profile From the Users (edit function) works fine

UsersController.php

public function edit($id = null)
{
$this->viewBuilder()->setLayout('user');
$user = $this->Users->get($id, [
'contain' =>
]);
if ($this->request->is(['patch', 'post', 'put'])) {
if ($this->request->data['password'] == '') {
unset($this->request->data['password']);
}
$user = $this->Users->patchEntity($user, $this->request->data);

if ($this->Users->save($user)) {
$this->Flash->success(__('The user has been saved.'));
return $this->redirect(['action' => 'index']);
} else {
$this->Flash->error(__('The user could not be saved. Please, try again.'));
}
}
unset($user->password); // Unset the password so nothing is loaded or displayed in the form
$roles = $this->roles;
$this->set(compact('user', 'roles'));
$this->set('_serialize', ['user']);
$this->set('user_session', $this->request->getSession()->read('Auth.User'));
}


public function profile()
{
//Set Title
$this->set('title', 'Profile');
// Set the layout.
$this->viewBuilder()->setLayout('user');
$this->set('user_session', $this->request->session()->read('Auth.User'));

$Users = TableRegistry::get('Users');

$user_data = $Users->get($this->request->session()-
>read('Auth.User.id'));
if($this->request->is('put') AND !empty($this->request->getData()) )
{


$userdata = $Users->patchEntity($user_data, $this->request->getData(), [
'validate' => 'update_profile'
]);

if($userdata->errors())
{
// Form Validation TRUE
$this->Flash->error('Please Fill required fields');
}else
{
$user_data->name = $this->request->getData('full_name');
$user_data->username = $this->request->getData('username');
$user_data->email = $this->request->getData('email');
$user_data->image = $this->request->data['image']['names'];

//upload image
if(!empty($this->request->data['file']['names'])){
$filename = $this->request->data['file']['names'];
$url = Router::url('/', true) . 'img/' . $filenames;
print_r($url);
exit();
$uploadpath = 'img/';
$uploadfile = $uploadpath . $filenames;
if (move_uploaded_file($this->request->data['file']['tmp_name'], $uploadfile)) {
$user = $this->Users->newEntity();
$user_data->names = $filenames;
$user_data->image = $url;
}
}
// Form Validation FALSE
if($Users->save($user_data))
{
// User Session Update
$this->request->session()->write('Auth.User.name', $user_data['full_name']);
$this->request->session()->write('Auth.User.username', $user_data['username']);
$this->request->session()->write('Auth.User.email', $user_data['email']);
$this->request->session()->write('Auth.User.image', $user_data['image']);
$this->redirect('/Users/Profile');
$this->Flash->success('User has been Updated.');

}else{
$this->Flash->error(__('Unable to update user!'));
}

}
}

$this->set(compact('user_data'));
$this->set('_serialize', ['user_data']);
}


UsersTable.php

public function validationUpdate_profile(Validator $validator)
{
$validator
// User Funll Name Validation
->notEmpty('full_name')
// User Phone Validation
->notEmpty('email')
->allowEmpty('image')
->allowEmpty('image_dir');
return $validator;
}


Profile.ctp
Im not sure about this either

Notice (8): Uninitialized string offset: 0 [COREsrcViewHelperUrlHelper.php, line 174]

<?= $this->Html->image($user_data->image, ['alt' => 'User image','style' => 'height: 250px; width: 100%; display: block;']); ?>

echo $this->Form->create($user_data, ['type'=>'file']);
echo $this->Form->input('image', ['value' => $user_session['image'], 'type'=>'file']);

Two things

1) The way your code is written, the image upload block never gets called.

Lets assume you move the block to a place where it gets called. This worked on my setup. Note, I had to make a few changes to get it to work (like remove Route and change $this->request->getData to $this->request->data).

2) $this->request->data['image'] is an array. If you're trying to save the file name in $user_data->image you have to get $this->request->data['image']['name'].

Paste this in the proper area:

}else
{
$user_data->name = $this->request->data('full_name');
$user_data->image = $this->request->data['image']['name'];


//upload image
if(!empty($this->request->data['image']['name'])){
$filename = $this->request->data['image']['name'];
$url = WWW_ROOT . 'img/' . $filename;
$uploadpath = 'img/';
$uploadfile = $uploadpath . $filename;
if (move_uploaded_file($this->request->data['image']['tmp_name'], $uploadfile)) {
$user = $this->Users->newEntity();
$user_data->name = $filename;
$user_data->image = $url;
}
}

// Form Validation FALSE
if($Users->save($user_data))


I use this little block of code to help me figure out where the data for your image was being saved.

This is why I changed your ['file'] to ['image'].

I always use this to see if my data is coming through from my form or not.

if($this->request->is('put') AND !empty($this->request->getData()) )
{
echo '<pre>';
print_r($this->request->data);
print_r($_FILES);
echo '</pre>';
die;


Thank you it worked !
