File upload validation

[eluser]pistolPete[/eluser]
You access $_data before the validation ran, so $_data is empty.
So you can get the values of the uploaded file like this:

Code:

if($this->form_validation->run() == FALSE)
{                
    ....
}
else
{
    print_r($this->_data);
    ...
}

where does the “1” come from?

The "1" is the return value of print_r():

If you would like to capture the output of print_r(), use the return parameter. If this parameter is set to TRUE, print_r() will return its output, instead of printing it (which it does by default).

By the way:
How do you repopulate the form data if validation failed?
Have a look at the set_value() function: user_guide/libraries/form_validation.html#repopulatingform
Using this function you could omit code like that:

Code:

//send back to the view
$attributes['prod_name'] = $this->input->post('prod_name');
$attributes['prod_descr_long'] = $this->input->post('prod_descr_long');
$attributes['prod_aff_link'] = $this->input->post('prod_aff_link');
