数据名称未使用CakePHP Form保存到db

I am making an admin tool, for the site I am making, that allows the admin to make image uploads to a folder at the server, that stores images for a gallery. The file is being uploaded correctly but the image name isn't being placed on the database. The name should be placed at the table "gallery_images", on the "path" field. How can this be fixed?

I am using CakePHP 2.4.4

Controller

    <?php
class AdminsController extends AppController{

    public $components = array('RequestHandler');
    public function admin_index(){
        if(!$this->Session->check('Admin')){
        $this->Session->setFlash('Está a aceder a uma zona restrita. Por favor faça Login.');
        $this->redirect(array(
                                'controller' => 'admins',
                                'action' => 'login'));
        }
        $this->layout='admin_index';
    }
    public function add_foto() {            
        if(!$this->Session->check('Admin')){
        $this->Session->setFlash('Está a aceder a uma zona restrita. Por favor faça Login.');
        $this->redirect(array(
                                'controller' => 'admins',
                                'action' => 'login'));
        }
        $this->layout='admin_index';
        $file=$this->request->data['gallery_images']['path'];
        if($this->request->is('post') || $this->request->is('put')){
                $this->Admin->create();
            $this->Admin->save($file);
            move_uploaded_file($this->data['gallery_images']['path']['tmp_name'], $_SERVER['DOCUMENT_ROOT'] . '/html/PushUp_app/app/webroot/img/gallery/' . $this->data['gallery_images']['path']['name']);
                     if($this->Admin->save($this->request->data)){
                     $this->Session->setFlash(__('Ficheiro carregado com sucesso!'));
            }
        }
        //$this->Admin->id = $id;
        //$this->Post->save($data=array($this->data['Admins']['path']), $params=array('fieldList'=>'path'));
        //$this->Post->saveField('path', $this->data['Admins']['path']);
            /*if ($this->ModelName->save($this->request->data)) {
                $this->Session->setFlash('Data Saved!');
            }*/
        //if($this->request->is('post')){
        //  $this->Admin->save($this->request->data);
            //}
        //}
    }
}
    ?>

View

    <h2>Adicionar Fotografia</h2>
    <?php
echo "<br>";
echo $this->Form->create('Admin',array('type'=>'file'));
echo $this->Form->file('gallery_images.path');
echo "<br>";
//echo $this->Form->submit();
echo $this->Form->end('Guardar');
//validação é feita no AdminsController
    ?>

    Controller

        <?php
        class GalleryController extends AppController {
    
        public function admin_upload_image(){
            $this->layout = 'admin_index';
            if($this->request->is('post') || $this->request->is('put')) {
              /*  $file = $this->request->data['gallery_images']['path']['name'];*/
            $file = array(
                    'GalleryImage' => array(
                    'path' => $this->request->data['gallery_images']['path']['name']
                                            )

    admins db table is:

    • model Admin, your app file: ../app/Model/Admin.php,
    • controller in your app file: ../app/Controller/AdminsController.php,
    • action/function add_foto() in Your controller AdminsController.php.

    gallery_images db table is:

    • model GalleryImage, your app file: ../app/Model/GalleryImage.php,
    • controller in your app file: ../app/Controller/GalleryImagesController.php

    Read more about Cake naming conventions: http://book.cakephp.org/2.0/en/getting-started/cakephp-conventions.html


    1. - SAVE ONE TABLE

    If You want to save data to gallery_images, You have to create form for GalleryImage, like:

    VIEW: ../app/View/GalleryImages/add_foto.ctp

      echo $this->Form->create('GalleryImage', array('type' => 'file')); // << db table gallery_images        
              // ...
          echo $this->Form->input('admin_id', array('value' => $admin_id)); // << id of db table admins
              // ...
          echo $this->Form->file('path'); // << your field of db table gallery_images
              // ... 
      echo $this->Form->end('Guardar');
    

    CONTROLLER: ../app/Controller/GalleryImagesController.php

    public function add_foto() {
        // ...  
        // debug($this->request->data); die(); // << You can see Your data  
        if($this->request->data){
            // ...
            $this->GalleryImage->save($this->request->data);
            // ...
        };
        // ...
    }
    


    2. SAVE MANY TABLES

    If You want to save data to db table admins and gallery_images in the same time (one form). You have to use $this->YourModelName->saveAll($this->request->data), read more:http://book.cakephp.org/2.0/en/models/saving-your-data.html

    and You have to define model relations/link models: belongs_to/has_many first, like:

    MODEL: Admin.php:

    var $hasMany = array(       
                    'GalleryImage' => array(
                        'dependent' => true 
                    ),
                 );
    

    MODEL: GalleryImage.php

    var $belongsTo = array('Admin');
    


    Then VIEW: .../Admins/add_foto.ctp

    echo $this->Form->create('Admin', array('type' => 'file')); // << db table gallery_images
        // ...
        echo $this->Form->input('Admin.id', array('value' => $admin_id)); // << id of db table admins
        echo $this->Form->input('Admin.name');
        echo $this->Form->input('Admin.surname');
        // ...
        echo $this->Form->input('GalleryImage.0.admin_id', array('value' => $admin_id)); // << id of db table admins
        echo $this->Form->file('GalleryImage.0.path'); // << your field of db table gallery_images
        // ... 
        echo $this->Form->input('GalleryImage.1.admin_id', array('value' => $admin_id)); // << id of db table admins
        echo $this->Form->file('GalleryImage.1.path'); // << your field of db table gallery_images
        // ...
    echo $this->Form->end('Guardar');
    

    And CONTROLLER: ../Controller/AdminsController.php

    public function add_foto() {
            // ...      
            if($this->request->data){
                // ...
                $this->Admin->saveAll($this->request->data);
                // ...
            };
            // ...
        }
    

    Hope this help.
