Why is this upload file code not working in CakePHP

Question

I have a problem with the upload of files in CakePHP 2.1. In fact, I always have the error:

Column not found: 1054 Unknown column 'Array' in 'field list'.

for the view:

<?php echo $this->Form->create('Ecole',array('enctype' => 'multipart/form-data')); ?>
<?php echo $this->Form->input('Ecole.logo_ecole', array('type'=>'file','class'=>'','label'=>'')); ?>

When I remove array('enctype' => 'multipart/form-data') I don't have the error but the upload don't work either.

For the controller:

if(!empty($this->data))
{    
  debug($this->data);
  $ext  = 'jpg';

  // Save success
  if($this->Ecole->save($this->data))
  {      
    // Destination folder, new filename and destination path
    $dest_folder = IMAGES . DS . 'galleries' . DS . $this->Ecole->id;
    $new_filename = $this->Ecole->id. '.' .$ext;
    $dest_path = $dest_folder . DS . $new_filename;

    // Check if destination folder exists and create if it doesn't
    if(!is_dir($dest_folder))
    {
      mkdir($dest_folder, 0755, true);
    }

    // We move the picture and rename it with his id
    if(move_uploaded_file($this->data['Ecole']['logo_ecole']['tmp_name'], $dest_path))
    {
      // Show success flash message
      $this->Session->setFlash(__('Picture successfully added !', true), 'default', array('class' => 'success'));
        echo  "<script>  parent.location.reload(true); parent.jQuery.fancybox.close(); </script>";
    }
    // Move failed
    else
    {
      // Delete picture
      //$this->Ecole->delete($this->Ecole->id);

      // Show error flash message
      $this->Session->setFlash(__('Error occurred while adding picture !', true), 'default', array('class' => 'error'));
    }
  }
  // Save failed
  else
  {      
    // Show error flash message
    $this->Session->setFlash(__('Error occurred while adding picture !', true), 'default', array('class' => 'error'));
  }
}

Can anyone explain what I'm doing wrong and how to do it right?

Answer 1

to do multipart/form-data, you have to specify it this way with the helper

 <?php echo $this->Form->create('Ecole', array('type' => 'file')); ?>

The type can be 'post', 'get', 'file', 'put' or 'delete' . Please see the sections Options for create here in the FormHelper documentation !

Answer 2

It's probably because you're trying to save the array cake generates when uploading a file ( $this->data['Ecole']['logo_ecole'] is an array). Are you meaning to save only the filename to the database?

i have modify your code please take a look

and please not remove array('enctype' => 'multipart/form-data') this line in form

<?php

if(!empty($this->data))
{    
    debug($this->data);
    $ext  = 'jpg';


      // Destination folder, new filename and destination path
    $dest_folder = IMAGES . DS . 'galleries' . DS . $this->Ecole->id;
    $new_filename = $this->Ecole->id. '.' .$ext;
    $dest_path = $dest_folder . DS . $new_filename;

    // Check if destination folder exists and create if it doesn't
    if(!is_dir($dest_folder))
    {
      mkdir($dest_folder, 0755, true);
    }

    $image='';

    // We move the picture and rename it with his id
    if(move_uploaded_file($this->data['Ecole']['logo_ecole']['tmp_name'], $dest_path))
    {
        $image = basename($this->data['Ecole']['logo_ecole']['name'])

        // Show success flash message
        $this->Session->setFlash(__('Picture successfully added !', true), 'default', array('class' => 'success'));
        echo  "<script>  parent.location.reload(true); parent.jQuery.fancybox.close(); </script>";

    }else
    {
      // Delete picture
      //$this->Ecole->delete($this->Ecole->id);

      // Show error flash message
      $this->Session->setFlash(__('Error occurred while adding picture !', true), 'default', array('class' => 'error'));
    }   


    $this->data['Ecole']['logo_ecole'] = $image;

      // Save success
      if(!$this->Ecole->save($this->data))
      {      
        // Show error flash message
        $this->Session->setFlash(__('Error occurred while adding picture !', true), 'default', array('class' => 'error'));
      }

}
