CakePHP3 - Upload image file - php

Question

I am new in cakephp3. I have an Employee Table and I want to save an image path.
Below is my form in add.ctp
<?php echo $this->Form->create($employee, ['enctype' => 'multipart/form-data']); ?>
<fieldset>
<legend><?= __('Add Employee') ?></legend>
<?php
echo $this->Form->input('image_path', ['type' => 'file']);
echo $this->Form->input('first_name');
echo $this->Form->input('last_name');
echo $this->Form->input('birthday',
array(
'type' => 'date',
'label' => 'Birthday',
'dateFormat' => 'MDY',
'empty' => array(
'month' => 'Month',
'day' => 'Day',
'year' => 'Year'
),
'minYear' => date('Y')-130,
'maxYear' => date('Y'),
'options' => array('1','2')
)
);
echo $this->Form->input('address');
echo $this->Form->input('contact');
echo $this->Form->input('date_hired',
array(
'type' => 'date',
'label' => 'Date Hired',
'dateFormat' => 'MDY',
'empty' => array(
'month' => 'Month',
'day' => 'Day',
'year' => 'Year'
),
'minYear' => date('Y')-130,
'maxYear' => date('Y'),
'options' => array('1','2')
)
);
$status = array(
"employed" => "Employed",
"unemployed" => "Unemployed"
);
echo $this->Form->input('status', array('label'=>'Status', 'type'=>'select', 'options'=>$status));
?>
</fieldset>
<?= $this->Form->button(__('Submit')) ?>
<?= $this->Form->end() ?>
I want to make the upload function work in my EmployeesController.php. I have tried to save it using php move_uploaded_file but it is not working. Below is the controller.
public function add()
{
$employee = $this->Employees->newEntity();
if ($this->request->is('post')) {
$employee = $this->Employees->patchEntity($employee, $this->request->data);
$employee->user_id = $this->Auth->user('id');
if ($this->Employees->save($employee)) {
$this->Flash->success(__('The employee has been saved.'));
return $this->redirect(['action' => 'index']);
} else {
$this->Flash->error(__('The employee could not be saved. Please, try again.'));
}
if(!empty($this->data))
{
//Check if image has been uploaded
if(!empty($this->data['employees']['image_path']['name']))
{
$file = $this->data['employees']['image_path']; //put the data into a var for easy use
$ext = substr(strtolower(strrchr($file['name'], '.')), 1); //get the extension
$arr_ext = array('jpg', 'jpeg', 'gif'); //set allowed extensions
//only process if the extension is valid
if(in_array($ext, $arr_ext))
{
//do the actual uploading of the file. First arg is the tmp name, second arg is
//where we are putting it
move_uploaded_file($file['tmp_name'], WWW_ROOT . 'CakePHP/app/webroot/img/' . $file['name']);
//prepare the filename for database entry
$this->data['employees']['product_image'] = $file['name'];
}
}
//now do the save
$this->Employees->save($this->data) ;
}
}
$users = $this->Employees->Users->find('list', ['limit' => 200]);
$this->set(compact('employee', 'users'));
$this->set('_serialize', ['employee']);
}

Try this structure in your View
<?= $this -> Form -> create($employee, ['type' => 'file']) ?>
...
<?= $this -> Form -> input('image_path', ['type' => 'file', 'label' => __('Select Image')]) ?>
<?= $this -> Form -> input('first_name') ?>
...
<?= $this -> Form -> end() ?>
Controller
public function add()
{
$employee = $this->Employees->newEntity();
if ($this->request->is('post'))
{
$employee = $this->Employees->patchEntity($employee, $this->request->data);
$employee['user_id'] = $this->Auth->user('id');
//Check if image has been uploaded
if(!empty($this->data['employees']['image_path']['name']))
{
$file = $this->data['employees']['image_path']; //put the data into a var for easy use
$ext = substr(strtolower(strrchr($file['name'], '.')), 1); //get the extension
$arr_ext = array('jpg', 'jpeg', 'gif'); //set allowed extensions
//only process if the extension is valid
if(in_array($ext, $arr_ext))
{
//name image to saved in database
$employee['product_image'] = $file['name'];
$dir = WWW_ROOT . 'img' . DS; //<!-- app/webroot/img/
//do the actual uploading of the file. First arg is the tmp name, second arg is
//where we are putting it
if(!move_uploaded_file($file['tmp_name'], $dir . $file['name']))
{
$this -> Flash -> error(__('Image could not be saved. Please, try again.'));
return $this->redirect(['action' => 'index']);
}
}
}
//now do the save
if ($this->Employees->save($employee))
{
$this->Flash->success(__('The employee has been saved.'));
return $this->redirect(['action' => 'index']);
} else {
$this->Flash->error(__('The employee could not be saved. Please, try again.'));
}
}
$users = $this->Employees->Users->find('list', ['limit' => 200]);
$this->set(compact('employee', 'users'));
$this->set('_serialize', ['employee']);
}
