Reading Variables CakePhp (assistance Needed)

Hi All,

I have a component which contains a variable and I need to read it from my controller.

Here is the code:

<?php
class FileUploadComponent extends Object {
      var $components = array('RequestHandler');
      
      function upload($data) {
            
            
            $folder = '203jfjg546650f0gf405764455887';
            
            mkdir md5($folder);
            
            
            
            $destination = 'img/uploads/'.md5($folder).'/'.$data['name'];
            if(move_uploaded_file($data['tmp_name'], $destination)) {
                  
                  return true;
            }  
            return false;
      }
}
?>

Can anyone help please?

Thanks

Which variable? $destination?

Make it a class property. See the code
class FileUploadComponent extends Object {
  //...

  protected $destination;

  public function upload($data) {
    //...
    $this->destination = 'img/uploads/'.md5($folder).'/'.$data['name'];
    //...
  }

  public function getDestination() {
    return $this->destination;
  }
}

// to access the variable:

$component = new FileUploadComponent();
$component->upload(...);
$variable = $component->getDestination();

Hi NetExpert... Couldn't get it to work but it's propably me ... I might have done something wrong.

Here is the actual component code.

Could you help me sort the code out so the variables can be accessed please?

Here is the code in full:

/***********************************/
* component
/***********************************/
<?php
class FileUploadComponent extends Object {
      var $components = array('RequestHandler');
      

      function upload($data) {
            
            
            $folder = '1223322';
            $tempdest  = 'img/uploads/';
            $random = rand(1111111111, 9999999999);
            
            mkdir($tempdest.''.$random.''.md5($folder));
            
            $fullpath = $tempdest.''.$random.''.md5($folder);
            
            
            $this->Cookie->write('rfname',$fullpath);
            
            $destination = 'img/uploads/'.$random.''.md5($folder).'/'.$data['name'];
            if(move_uploaded_file($data['tmp_name'], $destination)) {
                  
                  return true;
            }  
            return false;
      }
}
?>

Hope you can help.

Thanks

Tell me which variables you want to access please.

In general, declare each variable, you want to access, in the classes scope instead of in functions scope. If you declare them with public modifier (or without any), you will be able to access them in a $component->variable way.

Folder and destination please.

NetExpert-WarszawaCommented:
getDestination() and getFolder() will return the variables you want.
/***********************************/
* component
/***********************************/
<?php
class FileUploadComponent extends Object {
      var $components = array('RequestHandler');
      protected $folder;
      protected $destination;
      
      function upload($data) {            
            
            $this->folder = '1223322';
            $tempdest  = 'img/uploads/';
            $random = rand(1111111111, 9999999999);
            
            $fullpath = $tempdest.$random.md5($this->folder);
            mkdir($fullpath);                        
            
            $this->Cookie->write('rfname',$fullpath);
            
            $this->destination = $fullpath.'/'.$data['name'];
            if(move_uploaded_file($data['tmp_name'], $this->destination)) {
                  
                  return true;
            }  
            return false;
      }

  public function getDestination() {
    return $this->destination;

  public function getFolder() {

Can you give me a usage example so I can try it please?

I've tried using this on the controller:

$component = new FileUploadComponent();
$test = $component->getFolder();
                  echo $test;

It shows no errors but no results either.

I'm I doing it wrong?

Notice that variables receive their values in upload method.
$component = new FileUploadComponent();
$component->upload(array('name'=>'blablabla'));
$test = $component->getFolder();
echo $test;

It's perfect ... just 1 thing ... I'm getting an error .. seems like somthings broken in the component?

Notice (8): Undefined index:  tmp_name [APP/controllers/components/file_upload.php, line 21]

Any ideas pls?

NetExpert-WarszawaCommented:
Line 21 is:
$this->destination = $fullpath.'/'.$data['name'];
and 22:
if(move_uploaded_file($data['tmp_name'], $this->destination)) {

As you can see $data is an array and needs to have at least two indexes 'name' and 'tmp_name'.
$component = new FileUploadComponent();
$component->upload(array('name'=>'blablabla', 'tmp_name'=>'tmp_blabla'));
$test = $component->getFolder();
echo $test;
