Multiple Images Upload in CakePHP



In this post we will see how to uload multiple images in cakephp.I am going to show the additional code for multiple image handling for both the action Add and Edit.What all you need is to simply copy paste in your application according to needs.

My table : posts

CREATE TABLE `posts` (
`id` int(10) NOT NULL AUTO_INCREMENT,

`title` varchar(200) NOT NULL,

`body` text NOT NULL,

`image1` varchar(200), 

`image2` varchar(200), 

`image3` varchar(200),
PRIMARY KEY (`id`)
)

As you can see what are the fields of my 'posts' table.I have three fields for the images.Example: image1,image2,image3 etc.You may have different fields. Add the code given below for multiple image handling.

My uploaded images are stored in  app/webroot/img/uploads/posts  folder.I have one default image called 'no-icon.jpg' in the same folder which will be shown if the correct image is not available or in case of NULL value.

Controller : PostsController.php


Add Function

public function add() {

$this->Post->create();

if ($this->request->is('post')) {



// Image Handling code START //////

for($i=1;$i<4;$i++)

{

if(empty($this->data['Post']['image'.$i]['name'])){
unset($this->request->data['Post']['image'.$i]);
}
if(!empty($this->data['Post']['image'.$i]['name']))
{
$file=$this->data['Post']['image'.$i];
$ary_ext=array('jpg','jpeg','gif','png'); //array of allowed extensions
$ext = substr(strtolower(strrchr($file['name'], '.')), 1); //get the extension
if(in_array($ext, $ary_ext))
{
move_uploaded_file($file['tmp_name'], WWW_ROOT . 'img/uploads/posts/' . mktime().$file['name']);
$this->request->data['Post']['image'.$i] = mktime().$file['name'];
}
}
}
// Image Handling code END //////

  if ($this->Post->save($this->request->data)) 
  {
$this->Session->setFlash('Your post has been saved.');
$this->redirect(array('action' => 'index'));
}
else 
{
$this->Session->setFlash('Unable to add your post.');
}
}
}


Edit Function

public function edit($id=null){

if(!$id)

{

throw new NotFoundException(__('Invalid Post'));

}



$post=$this->Post->findById($id);
if(!$post)
{
throw new NotFoundException(__('Invalid Post'));
}
if(!empty($this->data))
{
$this->Post->id=$id;
                                
// Image Handling code START //////
for($i=1;$i<4;$i++)
{
if(empty($this->data['Post']['image'.$i]['name'])){
unset($this->request->data['Post']['image'.$i]);
}
if(!empty($this->data['Post']['image'.$i]['name']))
{
if(file_exists("img/uploads/posts/".$this->data['Post']['hiddenimage'.$i])){
  unlink("img/uploads/posts/".$this->data['Post']['hiddenimage'.$i]);
    }
$file=$this->data['Post']['image'.$i];
$ary_ext=array('jpg','jpeg','gif','png'); //array of allowed extensions
$ext = substr(strtolower(strrchr($file['name'], '.')), 1); //get the extension
if(in_array($ext, $ary_ext))
{
move_uploaded_file($file['tmp_name'], WWW_ROOT . 'img/uploads/posts/' . mktime().$file['name']);
$this->request->data['Post']['image'.$i] = mktime().$file['name'];
}
}
}
        // Image Handling code END //////
if($this->Post->save($this->request->data))
{
$this->Session->setFlash('Your Post has been Updated');
$this->redirect(array('action'=>'index'));
}
else
{
$this->Session->setFlash('Unable to update your post.');
}
}
if(!$this->request->data){
$this->request->data=$post;
}
}

To do this, at first we have to create a xml layout to hold the EditText fields. So create an android project and name it DatePickerExample. In the main.xml file just try to write this simple code....

How to construct a B+ tree with example

Image
A B+ tree contains n-1 search key values K1K2…….Kn-1 and have n pointers.   In a B+ tree the data are ordered  sequentially.  The leaf node may hold up to n pointers and must hold at least N/2 pointers. The root node must hold at least two pointers, unless the tree consists of only one node.  Now we construct a B+ tree. Construct a B+ tree for the following set of key values: (2,3,5,7,11,17,19,23,29,31) Assume that the tree is initially empty and values are added in ascending order. Construct a B+ tree where the pointer number is Four. Solution: When a node exceeds n-1 search key value then we split it into two nodes. First node contains (ceiling(n-1)/2) values.  2 nd node contains remaining node. Copy the smallest search key value of the second node to the parent node. Let's start, we know each node has N pointer and has N-1 search key values. In our example pointer number is 4, so the search key value is 4-1=3. So each node has 4 pointers and 3 search key val...

Conflict Serializability in database

Image
To maintains database state consistency we introduce serializability. Using serializability we can understand which schedule will ensure consistency, and which schedule will not. When we are capable of converting a concurrent schedule into a serial schedule then we cal it serializable schedule. A schedule is serializable if it is equivalent to a serial schedule. We divided this concepts into two parts 1. Conflict serializability  & 2. View serializability In this discussion I just clarify you the conflict serializability. Consider two instruction read, write and the data item A and B. When two instruction execute different data item such as read(A) and read(B), then we can swap the instruction without affecting the result of the schedule. But when the data item is equivalent to one another we need to consider following four condition.    a.   read (A ),    read ( A ).   they   don’t conflict.    b.   read ( Q),  ...
