单浏览多个图像上传
首先，我想尽你所能感谢你们的贡献和帮助。
现在我想问一些事情，也许不是什么大问题，但即使我已经尝试了很多不同的方法，我也找不到解决它的方法。
所以要详细解释..我有一个 typology_pictures 表，它有id | typology_id | pic_path。
当用户想要创建一个新的typology_picture时，它会显示如下：
因此，用户选择这些图片所包含的类型，当他眉毛时，我想让他选择多个图像。 当他按下提交时，所有图像都插入数据库中，每个图像都在一个新行中，但 typology_id 是相同的，只是pic_path是不同的。
所以模型是这样的：
<?php
App::uses('AppModel', 'Model');
/**
* TypologyPicture Model
*
* @property Typology $Typology
*/
class TypologyPicture extends AppModel {
public $name = 'TypologyPicture';
public $primaryKey = 'id';
public $displayField = 'typology_id';
public $validate = array(
'id' => array(
'blank' => array(
'rule' => 'blank',
'on' => 'create',
),
),
'typology_id' => array(
'numeric' => array(
'rule' => array('numeric'),
'message' => 'Chose the Typology this pic belongs to?',
),
'notEmpty' => array(
'rule' => array('notEmpty'),
'message' => 'Select The typology where these picture belongs to? ',
'on' => 'create',
),
),
'pic_path' => array(
'uploadError' => array(
'rule' => 'uploadError',
'message' => 'The Typology Image upload failed.',
'allowEmpty'=>false,
'on' => 'create',
),
'fileSize' => array(
'rule' => array('fileSize', '<=', '3MB'),
'message' => 'Cover image must be less than 3MB.',
'allowEmpty'=>false,
'on' => 'create',
),
'processTypologyImageUpload' => array(
'rule' => 'processTypologyImageUpload',
'message' => 'Unable to process cover image upload.',
'allowEmpty' => TRUE,
),
),
);
//The Associations below have been created with all possible keys, those that are not needed can be removed
/**
* belongsTo associations
*
* @var array
*/
public $belongsTo = array(
'ItemTypologyPicture' => array(
'className' => 'Typology',
'foreignKey' => 'typology_id',
'conditions' => '',
'fields' => '',
'order' => ''
)
);

// This new function Doesent Upload the Picture or Image unless the Record is inserted in DB.

chmod(WWW_ROOT . $dir, 0777);

unlink($img);
return true;
} else { $this->data[$this->alias]['pic_path'] = $this->image['TypologyPicture']['pic_path'];}
return true;
}
// this is a Global variable that im gonna use it inside my function
private $TypologyPicture;
public function beforeDelete($cascade = true) {
// first we grab slider id, and we pass it's data the the variable.
$this->TypologyPicture = $this->find('first', array('conditions' => array('TypologyPicture.id' => $this->id)));
return true;
}
public function afterDelete() {
//$dir = 'img/uploads/typology/images/'; /*<=== DO NOT EDIT*/
$dir = 'img' . DS . 'uploads' . DS . 'typology' . DS . 'images' . DS;

$img = WWW_ROOT . $dir . $this->TypologyPicture ['TypologyPicture']['pic_path'];
unlink($img);
return true;
}
return true;
}
}
添加操作的控制器：
public function add() {
$this->layout='typology_add';
if ($this->request->is('post')) {
if (!empty($this->data)) {
$this->TypologyPicture->create();
if(empty($this->data['TypologyPicture']['pic_path']['name'])){
unset($this->request->data['TypologyPicture']['pic_path']);
}
if ($this->TypologyPicture->saveAll($this->data))
{
$this->Session->setFlash(__('The profile has been saved', true));
$this->redirect(array('action' => 'index'));
} else
{
$this->Session->setFlash(__('The profile could not be saved. Please, try again.', true));
} // END OF TypologyPicture->save
} // END OF THE !empty();
if (empty($this->data)) {
$this->data = $this->TypologyPicture->read(null, $id);
}
}
$typologies = $this->TypologyPicture->ItemTypologyPicture->find('list');
$this->set(compact('typologies'));
}
观点如下：
<?php echo $this->Form->create('TypologyPicture', array('type'=>'file')); ?>
<legend><?php echo __('Add Typology Pictures'); ?></legend>
<?php
echo $this->Form->input('id');
echo $this->Form->input('typology_id');
echo $this->Form->input('pic_path', array('label'=>'Picture','type'=>'file'));
?>
<?php echo $this->Form->end(__('Submit')); ?>
我真的很高兴你的帮助。
感谢名单！
修改
这是我到目前为止编写的代码！
public function add() {
if ($this->request->is('post')) {
$dir = 'img' . DS . 'uploads' . DS . 'typology' . DS . 'images' . DS;
for($i=0;$i<count($this->request->data['TypologyPicture']['pic_path']['name']);$i++){
if(empty($this->data['TypologyPicture']['pic_path'][$i]['name'])) {
unset($this->request->data['TypologyPicture']['pic_path'][$i]['name']);
}
if(!empty($this->request->data['TypologyPicture']['pic_path'][$i]['tmp_name'])){
$allowedExts = array('jpeg', 'png', 'jpg', 'gif','tiff');
$value = explode(".", $this->data['TypologyPicture']['pic_path'][$i]['name']); // Here we grab the name of the file with the extension
$extension = strtolower(array_pop($value)); //extension
if(in_array($extension, $allowedExts)){
if ($this->data['TypologyPicture']['pic_path'][$i]['error'] <= 0) {
chmod(WWW_ROOT . $dir, 0777);
move_uploaded_file($this->data['TypologyPicture']['pic_path'][$i]['tmp_name'], WWW_ROOT . $dir . mktime().$this->data['TypologyPicture']['pic_path'][$i]['name']);
$this->request->data['TypologyPicture']['pic_path'] = mktime().$this->data['TypologyPicture']['pic_path'][$i]['name'];
}
}
}
$this->TypologyPicture->create();
if ($this->TypologyPicture->save($this->data)){
$this->Session->setFlash(__('The profile has been saved', true));
$this->redirect(array('action' => 'index'));
} else {
$this->Session->setFlash(__('The profile could not be saved. Please, try again.', true));
} // END OF ItemPicture->save
}
}
$typologies = $this->TypologyPicture->ItemTypologyPicture->find('list');
$this->set(compact('typologies'));
}
我还将输入字段更改为：
echo $this->Form->input('pic_path.', array('label'=>'Picture','multiple'=>'multiple' ,'type'=>'file'));
为了支持多文件选择。但似乎没有什么工作......
我得到一个：
请求已被黑洞错误：在此服务器上找不到请求的地址'/ cesifull / typology_pictures / add'。
任何建议......任何人！

能够通过单个文件输入选择多个文件是HTML5功能，因此您编写的任何解决方案都很可能涉及HTML5。如果您不想使用HTML5，那么人们也可以为多个图像上传制作Flash和Java插件。
