Multiple File Upload in cakephp by one user and save the images name  in one column in database :

Hello readers, This is a small blog on how to upload multiple file in cakephp. This is very simple and useful code, hope this code will be helpful for our users. 

Step 1: Create a table  named  users in your database

CREATE TABLE `images` (
`id` int(11) NOT NULL PRIMARY KEY,
`name` VARCHAR(45) ,
`email` VARCHAR(255)

);

Step 2:  Next create a form having  input type file and  multiple, set enctype'=>'multipart/form-data. code will be like:

<?php echo $this->Form->create('User', array('enctype' => 'multipart/form-data'));?>

  echo $this->Form->input('image.', array('type'=>'file', 'multiple'));

Step 3: Now make a function in your controller (ex-UsersController) and add  the following code

  $n = count($this->data['User']['image']);
         
                    if(!empty($this->request->data['User']['image']))
                    {
                      
                        for($i= 0;$i < $n; $i++){
                        $file=$this->data['User']['image'];
        
                        $ary_ext=array('jpg','jpeg','gif','png'); //array of allowed extensions
                        $ext = substr(strtolower(strrchr($file[$i]['name'], '.')), 1); //get the extension
                            if(in_array($ext, $ary_ext))
                            {
                            move_uploaded_file($file[$i]['tmp_name'], WWW_ROOT . 'upload/' . time().$file[$i]['name']);
                            $name = time().$file[$i]['name'];
                            $name_arr[$i] = $name;
                                       
                                                                          
                            }
                        }
                  
                        $name_str=implode(',', $name_arr);
                    }
                        $this->request->data['User']['image'] = $name_str;
