Hi all,
I'm my view I am getting the following error:
Fatal error: Cannot use string offset as an array in ...

After adding this code:
echo $form->hidden('user_id', array('value'=>'37'));

The error is pointing to this code:
if($file['file']['error'] != 0) continue;

Just in case it helps ... here is the controller and view code:

/*****************************************/
/* Controller
/*****************************************/
<?php
class UploadsController extends AppController {
      
      var $name = 'Uploads';
      var $useTable = 'competitions_entry';
      var $components = array('RequestHandler','FileUpload');
      var $helpers = array('Html', 'Form', 'Javascript');
      
            
      function index() {
            $this->set('uploads', $this->Upload->find('all'));
            if($this->RequestHandler->isPost()) {
            $this->Upload->saveAll($this->data['Upload'], array('validate'=>'only')); // validation
            

            foreach($this->data['Upload'] as $number => $file) {
            if($file['file']['error'] != 0) continue; //do not save when PHP errors occur

            $this->Upload->create();
            if($this->Upload->save($file['file'],array('validate'=>false))) { // no need to validate now
            
            
            if(!$this->FileUpload->upload($file['file'])) {
            $this->Upload->delete($this->Upload->id); // remove the DB entry because there were upload errors
            }
            }
            }
            }
            }
            
} //end controller
?>


/**********************************/
/* The View
/********************************/
<?php
echo $form->create('Upload',array('type'=>'file', 'url' => 'uploads'));
echo $form->input('0.file',array('type'=>'file','label'=>'Image Upload: '));
echo $form->hidden('user_id', array('value'=>'37'));
echo $form->end('Submit');
?>

Hope you can help

Thanks

print_d($file);die();

right before the line

if($file['file']['error'] != 0) continue; //do not save when PHP errors occur

that will show you the actual array structure of $file

Change that line to:

echo $form->hidden('user_id');

I think what you should be doing is, before render in the controller, you should do:

Add this to your controller in the index() action:

$this->data['Upload']['user_id'] = 37

Not errors now but not saving to the table.

This is my controller now:

/*********************************/
/*  Controller
/********************************/
<?php
class UploadsController extends AppController {
      
      var $name = 'Uploads';
      var $useTable = 'competitions_entry';
      var $components = array('RequestHandler','FileUpload');
      var $helpers = array('Html', 'Form', 'Javascript');
      
            
      function index() {
            $this->set('uploads', $this->Upload->find('all'));
            
            if($this->RequestHandler->isPost()) {
            $this->data['Upload']['user_id'] = 37; //new line
            $this->Upload->saveAll($this->data['Upload'], array('validate'=>'only')); // validation
            
                foreach($this->data['Upload'] as $number => $file) {
            
            if($file['file']['error'] != 0) continue; //do not save when PHP errors occur

            $this->Upload->create();
            if($this->Upload->save($file['file'],array('validate'=>false))) { // no need to validate now
            
            
            if(!$this->FileUpload->upload($file['file'])) {
            $this->Upload->delete($this->Upload->id); // remove the DB entry because there were upload errors
            }
            }
            }
            }
            }
      
}
?>

and my view

/********************************************/
/*  View
/*******************************************/
<?php
echo $form->create('Upload',array('type'=>'file', 'url' => 'uploads'));
echo $form->input('0.file',array('type'=>'file','label'=>'Image Upload: '));
echo $form->hidden('user_id'); //Changed line
echo $form->end('Submit');
?>

The problem is that I have a file upload fuctionality which works fine and saves to the table. But when I upload the file I need to also add a couple of more fields to it, for example, the user_id.
I have tried  your last code as the only issue is that it's not saving the user_id value to the table. It's only inserting the image

Here is all the code:

/***********************************/
/* The Component
/*************************************/
<?php
class FileUploadComponent extends Object {
      var $components = array('RequestHandler');
      function upload($data) {
      $destination = 'img/uploads/'.$data['name']; // Create uploads folder and set proper permissions!
      if(move_uploaded_file($data['tmp_name'], $destination)) {
      return true;
      }
      return false;
      }
}
?>

/**********************************************/
/* The Model
/**********************************************/
<?php
class Upload extends AppModel {
var $name = 'Upload';
var $useTable = 'competitions_entry';
var $validate = array(
'file' => array(
'rule' => array('validateFile', false),
'message' => 'There is a problem with uploading the file.' //message
)
);
function validateFile($data, $required = false) {
$file = array_shift($data); // for easier handling
if ($required && $file['size'] == 0) return false; // If no file is uploaded
if ($file['error'] !== 0) return false;
return is_uploaded_file($file['tmp_name']); // If everything is fine
}
}
?>

/*****************************************/
/* Controller
/*****************************************/
<?php
class UploadsController extends AppController {
     
      var $name = 'Uploads';
      var $useTable = 'competitions_entry';
      var $components = array('RequestHandler','FileUpload');
      var $helpers = array('Html', 'Form', 'Javascript');
     
           
      function index() {
            $this->set('uploads', $this->Upload->find('all'));
            if($this->RequestHandler->isPost()) {
              $this->data['Upload']['user_id'] = 37; //new line ... not sure if in right place
            $this->Upload->saveAll($this->data['Upload'], array('validate'=>'only')); // validation
           

            foreach($this->data['Upload'] as $number => $file) {
            if($file['file']['error'] != 0) continue; //do not save when PHP errors occur

            $this->Upload->create();
            if($this->Upload->save($file['file'],array('validate'=>false))) { // no need to validate now
           
           
            if(!$this->FileUpload->upload($file['file'])) {
            $this->Upload->delete($this->Upload->id); // remove the DB entry because there were upload errors
            }
            }
            }
            }
            }
           
} //end controller
?>


/**********************************/
/* The View
/********************************/
<?php
echo $form->create('Upload',array('type'=>'file', 'url' => 'uploads'));
echo $form->input('0.file',array('type'=>'file','label'=>'Image Upload: '));
echo $form->hidden('user_id'); //NEW ... Not Saving to table
echo $form->end('Submit');
?>

This is all the code.
Hope you can help

thanks

Tried a var_dump on the view on data and got back null. That's after adding       $this->data['Upload']['user_id'] = 37; to the controller
