我正在尝试使用Uploader插件来创建一个结构，其中User模型可以使用Avatar模型上传它的头像，我已多次阅读说明但是当我尝试$this->Uploader->upload('Avatar.filename')时，我没有得到任何验证错误，但上传方法失败了。
以下是我编写User模型
<?php
class User extends AppModel {
public $name = 'User';
public $hasOne = array(
'Profile' => array(
'className' => 'Profile',
'conditions' => '',
'dependent' => true,
'foreignKey' => 'user_id',
'associatedKey' => 'user_id'
),
'Avatar' => array (
'className' => 'Avatar',
'foreignKey' => 'user_id',
'dependent' => true
)
);
public $validate = array(...);
// other stuff not relevant here...
?>
这是Avatar模型
<?php
class Avatar extends AppModel {
public $name = 'Avatar';
public $actsAs = array (
'Uploader.Attachment' => array (
'Avatar.filename' => array(
'name' => 'setNameAsImgId', // Name of the function to use to format filenames
'baseDir' => '', // See UploaderComponent::$baseDir
'uploadDir' => 'files/avatars/', // See UploaderComponent::$uploadDir
'dbColumn' => 'filename', // The database column name to save the path to
'importFrom' => '', // Path or URL to import file
'defaultPath' => '', // Default file path if no upload present
'maxNameLength' => 500, // Max file name length
'overwrite' => true, // Overwrite file with same name if it exists
'stopSave' => true, // Stop the model save() if upload fails
'allowEmpty' => true, // Allow an empty file upload to continue
'transforms' => array (
array('method' => 'resize', 'width' => 128, 'height' => 128, 'dbColumn' => 'name')
) // What transformations to do on images: scale, resize, ete
)
),
'Uploader.FileValidation' => array (
'Avatar.filename' => array (
'maxWidth' => array (
'value' => 512,
'error' => 'maxWidth error'
),
'maxHeight' => array (
'value' => 512,
'error' => 'maxWidth error'
),
'extension' => array (
'value' => array('gif', 'jpg', 'png', 'jpeg'),
'error' => 'extension error'
),
'filesize' => array (
'value' => 5242880,
'error' => 'filesize error'
)
)
)
);
public $belongsTo = array(
'User' => array(
'className' => 'User',
'foreignKey' => 'user_id',
'conditions' => '',
'order' => ''
)
);
public function setNameAsImgId ($name, $field, $file) {
/**
* Format the filename a specific way before uploading and attaching.
*
* @access public
* @param string $name - The current filename without extension
* @param string $field - The form field name
* @param array $file - The $_FILES data
* @return string
*/
// devo ricavare l'id dell'immagine appena creata per rinominare il file
return $name;
}
}
?>
这是UsersController方法的edit
<?php
App::uses('CakeEmail','Network/Email');
CakePlugin::load('Uploader');
App::import('Vendor', 'Uploader.Uploader');
class UsersController extends AppController {
public $name = 'Users';
public function edit ($id) {
$this->User->id = $id;
if (!$this->User->exists()) {
throw new NotFoundException ('Nessuna corrispondenza trovata per questo utente');
}
if (!$id) {
$this->set('flash_element','error');
$this->Session->setFlash ('Utente non valido');
}
$this->User->recursive = 1;
$this->set('user', $this->User->read());
if ($this->request->is('post')) {
$this->User->id = $this->request->data['User']['id'];
if (!$this->User->exists()) {
$this->set('flash_element','warning');
$this->Session->setFlash('Nessun utente trovato con questa corrispondenza');
}
if ($this->User->save($this->request->data)) {
$this->request->data['Profile']['user_id'] = $this->User->id;
$conditions = array(
'conditions' => array(
'Profile.id' => $this->request->data['Profile']['id']
)
);
if ($this->User->Profile->save($this->request->data, $conditions)) {
if (!empty($this->request->data['Avatar']['filename'])) {
$this->request->data['Avatar']['user_id'] = $this->User->id;
if ($this->User->Avatar->save($this->request->data)) {
$avatar = $this->User->Avatar->find('first', array(
'conditions' => array('Avatar.user_id' => $this->User->id)
));
$ext = Uploader::ext($this->request->data['Avatar']['filename']);
$filename = $avatar['Avatar']['id'].'.'.$ext;
if ($this->User->Avatar->save('Avatar.filename')) {
$this->set('flash_element','done');
$this->Session->setFlash('Avatar changed successfully');
debug('saved successfully');
} else {
debug('not saved');
$this->set('flash_element','warning');
$this->Session->setFlash('Avatar not saved on the server');
}
} else {
$this->Session->write('flash_element','error');
$this->Session->setFlash('Avatar data not saved on the server');
$this->redirect(array('action'=>'index'));
}
} else {
$this->Session->write('flash_element','done');
$this->Session->setFlash('Data successfully saved, avatar not changed');
$this->redirect(array('action'=>'index'));
}
} else {
$this->set('flash_element','error');
$this->Session->setFlash('Error on saving Profile data to the server');
}
} else {
$this->Session->write('flash_element','error');
$this->Session->setFlash('Error on saving User data to the server');
$this->redirect(array('action'=>'index'));
}
}
}
}
?>
在view文件中我有这个
<?php
echo $this->Form->create('User', array ('class' => 'form'));
echo $this->Form->input('User.id', array ('type'=>'hidden', 'value'=> $user['User']['id'],'label'=> false, 'id' => 'id'));
echo $this->Form->input('User.username', array ('label'=> false, 'value' => $user['User']['username'], 'id' => 'username', 'after' => '<div class="message">Message for username field'));
echo $this->Form->input('User.email', array ('label'=> false, 'value' => $user['User']['email'], 'id' => 'email', 'after' => '<div class="message">Message for email field</div>'));
echo $this->Form->input('UserOptions.id', array ('type'=>'hidden', 'value'=> $user['UserOptions']['id'],'label'=> false, 'id' => 'UserOptions.id'));
$attributes = array ('value' => $user['UserOptions']['avatar_type'], 'empty' => false);
$options = array('0' => 'This site', '1' => 'Gravatar');
echo $this->Form->select('UserOptions.avatar_type', $options, $attributes);
/* avatar code */
echo $this->Form->input('Avatar.id', array ('type'=>'hidden', 'value'=> $user['Avatar']['id'],'label'=> false, 'id' => 'Avatar.id'));
echo $this->Form->input('Avatar.filename', array('type' => 'file'));
/* end avatar code */
echo $this->Form->input('Profile.city', array ('label'=> false, 'value' => defaultValue ('City', $user['Profile']['city']), 'id' => 'city', 'after' => '<div class="message">Message for city field</div>'));
echo $this->Form->input('Profile.country', array ('label'=> false, 'value' => defaultValue('',$user['Profile']['country']), 'id' => 'country', 'after' => '<div class="message">Message for country field</div>'));
echo $this->Form->input('Profile.url', array ('label'=> false, 'value' => defaultValue('http://', $user['Profile']['url']), 'id' => 'url', 'after' => '<div class="message">Message for url field</div>'));
echo $this->Form->input('Profile.description', array ('label'=> false, 'value' => defaultValue('Description',$user['Profile']['description']), 'id' => 'description', 'after' => '<div class="message">Message for description field</div>'));
echo $this->Form->submit('Modifica', array('id'=>'edit'));
echo $this->Form->end();
?>
在Controller中，数据的每个部分都是saved，直到我到达$this->Uploader->upload('Avatar.filename', array('overwrite' => true, 'name' => $filename))，我才会收到一般错误。
这个插件似乎是最好的方法，没有写大量的代码，但我不知道如何使用它。 我不确定代码有什么问题，你可以帮我解决问题吗？
答案 0 :(得分：0)
我发现了问题，我忘记了两件事：
在view页面中，我忘记了'type' => 'file'
<?php
echo $this->Form->create('User', array ('class' => 'form', 'type' => 'file'));
?>
我习惯使用1.3版本，因此缺少app/Config/bootstrap.php配置：
<?php
CakePlugin::load('Uploader');
?>
现在有效！
